3 Product description


Product descriptionThis chapter contains an overview of the design and function of the product.

Function descriptionDuring each diverter switch operation, the OF 100 oil filter unit automaticallyhandles cleaning and, together with the combined filter cartridge, also dryingof the on-load tap-changer's insulating oil.

The flange connections for oil feed are located on the bottom cover of thepump unit, and the flange connections for oil return are located on the topcover. The pump draws in the insulating oil via the suction pipe of the on-load tap-changer and via the pipe for the forward flow. The insulating oil en-ters the tank of the pump unit and is pressed through the filter cartridge bythe pump, see also [► 52].

The cleaned insulating oil, or in the case of the combined filter cartridge thecleaned and dried insulating oil, leaves the pump unit via the return pipe andflows back through the return pipe connection to the on-load tap-changerhead.

In the standard version of the OF 100 oil filter unit, a pressure switch whichis set at the factory to 3.6 bar is used for remote signaling of the workingpressure. At a pressure of 3.6 bar, the pressure switch closes a signalingcontact and indicates that the limit value has been reached.

When the standard oil filter unit starts up at a low oil temperature, the pres-sure switch may trip due to the higher oil viscosity.Ignore this message when the oil temperature is under 20 °C.

The oil viscosity is greater and thus the working pressure is also higher attemperatures under 20 °C.

Special model with temperature switch

To prevent the pressure switch from issuing erroneous signals at tempera-tures below 20 °C, the pressure switch signal can be suppressed below20 °C at the request of the customer by an extra built-in temperature switch.

Model for cold weather operation

The model for cold weather operation is recommended for regions where thetemperatures may fall below 5 °C in the OF 100 oil filter unit or in the pipes.A thermostat which switches the oil filter unit to permanent operation whentemperatures fall below 0 °C is used for this purpose. The oil filter unit re-mains in permanent operation until the oil temperature exceeds +5 °C.

Performance features

The product is characterized by the following properties:▪ maintenance-free▪ clear piping routing▪ monitoring of permissible operating pressure▪ simple removal of filter insert▪ the OF 100's entire electrical control system is in the motor-drive unit

housing (standard model)

Criteria for operation

Use of an oil filter unit with paper filter cartridge is recommended for theoperation of on-load tap-changers in transformers with an annual number ofswitching operations of more than 15,000. The maintenance intervals cantherefore be extended.

Using an oil filter unit with combined filter cartridge also reduces the oil'swater content. NOTICE! If the combined filter cartridge is stipulated by themanufacturer in order to maintain particular dielectric properties of the insu-lating oil, paper filter cartridges must not be used.

If the oil filter unit is used in the oil cooling system, the use of combined filtercartridges is mandatory.

If necessary, on-load tap-changers already in operation can be retrofittedwith an oil filter unit following consultation with Maschinenfabrik ReinhausenGmbH.

To prevent deposits in the oil filter system, all the oil in the on-load tap-changer must be circulated at least twice after every tap-change operation.This is ensured by the oil filter unit's minimum pump run time:

On-load tap-chang-er

Minimum pump run time after each tap-change operation

Type V 30 minutesType M, MS 30 minutesType R, RM 60 minutesType T 60 minutesType G 90 minutes

Table 8: Factory setting of the minimum pump run time of the oil filter unit with paperor combined filter cartridge for various types of on-load tap-changers

Cleaning and dryingThe oil filter unit is used for cleaning or for cleaning and drying the insulatingoil in on-load tap-changers.

3.1.1

3.1.2

3.2



It can be equipped with a choice of a paper filter (for cleaning) or a combinedfilter (for cleaning and drying).

NOTICE Damage to oil filter unit and on-load tap-changer!The filter cartridge clogs up during the cleaning process.► Change the filter cartridge when the working pressure is greater than

3.6 bar at an oil temperature of more than 20 °C.

See Page [► 16] for the criteria applicable to use of the oil filter unit.

Cleaning insulating oil with paper filter

When on-load tap-changers are used under extremely difficult operatingconditions, e.g. in industrial transformers for furnace or electrolyte applica-tions (large number of switching operations, constant heavy loads and fre-quent overloading), arcing will contaminate the insulating oil relatively quick-ly.

The oil filter unit with paper filter cartridge is intended for these operatingconditions. The paper filter cleans solid particles out of the insulating oil. Thenumber of oil changes which are otherwise needed at short intervals for highswitching frequencies can be reduced.

The specific contamination of the insulating oil depends on the following fac-tors:▪ oil volume available [liters]▪ switching work [kWs]▪ frequency of switching operations

Cleaning and drying insulating oil with combined filter

When the on-load tap-changer is used in areas where humidity is extremelyhigh and the temperature in the oil conservator usually falls below the dewpoint every day, an increased water content in the insulating oil and an accu-mulation of water in the carbon deposited on the insulating materials can oc-cur. This will deteriorate the insulating properties of the on-load tap-changer.

The combined filter cartridge not only filters contaminating solid particles outof the insulating oil but also reduces the water content to a residual amountof less than 10 ppm. The oil monitoring required can be reduced, and undercertain circumstances the oil conditioning needed during maintenance maybe omitted.

The combined filter cartridge is equipped with a paper filter on the outside(filter grain size approx. 9 µm) and filled with a drying agent on the inside(granules approx. 4 kg).

3.2.1

3.2.2



NOTICE Damage to combined filter cartridge!The combined filter cartridge's drying agent is very hygroscopic. Damage tothe air-tight package will destroy the combined filter cartridge very quickly!► Check transport container with combined filter cartridge for damage.► Be sure to store the combined filter cartridge carefully in its air-tight

package.► Do not remove the combined filter cartridge from the transport container

until immediately before installation and commissioning.

Do not store combined filter cartridges for more than 4 years.Otherwise the trouble-free function of the filter unit cannot be guaranteed.

Packaging

Purpose

The packaging is designed to protect the packaged goods during transport,loading and unloading as well as periods of storage in such a way that no(detrimental) changes occur. The packaging must protect the goods againstpermitted transport stresses such as vibration, knocks and moisture (rain,snow, condensation).

The packaging also prevents the packaged goods from moving impermissi-bly within the packaging. The packaged goods must be prepared for ship-ment before actually being packed so that the goods can be transportedsafely, economically and in accordance with regulations.

Suitability

The packaging is suitable for▪ all common types of transportation▪ stackability - 1000 kg/m2 top surface

The packaged goods are packed in a stable wooden crate. This crate en-sures that the shipment is secure when in the intended transportation posi-tion and that none of its parts touch the loading surface of the means oftransport or touch the ground after unloading.

The packaged goods are stabilized inside the crate to prevent impermissiblechanges in position.

The sealed packaging surrounds the packaged goods on all sides with a PEfoil. The product is protected using desiccant. The PE foil is bonded after thedrying agent is added and any remaining air is extracted. This can be seenon the form-fit of the PE foil.

telephone and in writing, and prepare a damage report.▪ Observe the time periods applicable to such actions in the respective

country. Inquire about these in good time.

With hidden damage, it is very hard to make the transportation company (orother responsible party) liable. Any insurance claims for such damages canonly be successful if relevant provisions are expressly included in the insur-ance terms and conditions.

Storage of shipmentsPackaged goods with a functional sealed packaging can be stored outdoorswhen the following conditions are complied with.

Selection and arrangement of the storage location should meet the followingrequirements:▪ Stored goods are protected against moisture (flooding, water from melt-

ing snow and ice), dirt, pests such as rats, mice, termites and so on, andagainst unauthorized access.

▪ Store the crates on timber beams and planks as a protection against ris-ing damp and for better ventilation.

▪ Carrying capacity of the substrate under the goods is sufficient.▪ Entrance and exit paths are kept free.

Check stored goods at regular intervals. Also take appropriate action afterstorms, heavy rain or snow and so on.

Protect the packaging foil from direct sunlight so that it does not disintegrateunder the influence of UV rays, which would cause the packaging to lose itssealing function.

If installation of the product is delayed beyond the normal time frame, suita-ble measures must be taken without delay. The following measures can beused:▪ Correctly regenerate the drying agent and restore the sealed packaging.▪ Unpack the packed goods and store in suitable storage space (well ven-

tilated, as dust-free as possible, humidity < 50 % where possible).

10. Attach the connecting flange to the return pipe connection.11. Open stop-cocks for feed and return.



12. Vent tank at return flange.


13. Vent the feed pipe connection (suction pipe connection) on the on-loadtap-changer head.

Figure 14: Vent screw on on-load tap-changer head

14. Once work is complete, check oil level on on-load tap-changer oil con-servator and top up oil if necessary (amount depends on type of on-loadtap-changer). NOTICE! Ensure that the oil in the on-load tap-changeroil conservator is between the "Minimum" and "Maximum" marks, other-wise there is a risk of explosion from impermissible amount of oil in theon-load tap-changer oil system!

The pipe system must be vented at all points where air pockets could be lo-cated due to the laying of the pipe system.



Paper filter cartridge (4.8 kg)

For further commissioning of the paper filter cartridge, proceed as follows:1. Perform test run by actuating rotary switch S30.2. Vent again after performing the test run.3. Perform function test

with closed stop-cock for the return pipe.During operation of the oil filter unit, the manometer must indicate apressure of more than 3.6 bar.

Note the connection diagram applicable to your unit model, from page[► 59] onwards.

4. If the pressure is lower than this, check the motor voltage's phase se-quence on the oil filter unit's connection: U-V-W, clockwise. If the phase sequence differs from normal, the motor (3 AC) will not startdue to the return stop in the anti-friction bearings.

5. Check tripping value of pressure switch.The return pipe is choked by closing the stop-cock slowly. If the pres-sure switch is electrically connected the tripping pressure can be readfrom the manometer during signal output. In standard cases, the trippingpressure is 3.6 bar.

6. Set pump run time on time relay K29.The pump run time setting on time relay K29 is matched to the oil con-tent of the on-load tap-changer oil conservator and is undertaken in thefactory depending on the type of oil filter unit.Particular operating conditions may require a different pump time to beset.

7. Output a pulse on the motor-drive unit to check whether the oil filter unitautomatically starts when the motor-drive unit starts up.

Combined filter cartridge (14 kg including transport container)

For the criteria for mandatory use of an oil filter unit with combined filter car-tridge, see page [► 16].

NOTICE Damage to combined filter cartridge!The combined filter cartridge's drying agent is very hygroscopic. Moistureabsorbed from the surrounding air will damage the combined filter cartridge!► Only carry out the tasks of filling the tank with oil and installing the filter

cartridge in quick succession and without any interruptions just beforecommissioning the oil filter unit.

Only use new mineral insulating oil for transformers as per IEC 60296 (Spec-ification for unused mineral insulating oils for transformers and switchgear)with a dielectric strength of ≥ 60 kV/2.5 mm and a residual water content of≤ 12 ppm.

6.3.1

6.3.2



Ensure that the oil quality is not affected by dirty filling equipment.

If an on-load tap-changer has already been in operation and an oil filter unitis being retrofitted, the insulating oil and insulating materials surrounded bythis oil (diverter switch insert and inner surface of oil compartment) must bethoroughly cleaned before commissioning.

For further commissioning of the combined filter cartridge, proceed as fol-lows:1. Perform test run by actuating rotary switch S30.2. Vent again after performing the test run.3. Perform function test

with closed stop-cock for the return pipe.During operation of the oil filter unit, the manometer must indicate apressure of more than 3.6 bar.

Note the connection diagram applicable to your unit model, from page[► 59] onwards.

4. If the pressure is lower than this, check the motor voltage's phase se-quence on the oil filter unit's connection: U-V-W, clockwise. If the phasesequence differs from normal, the motor (3 AC) will not start due to thereturn stop in the anti-friction bearings.

5. Check tripping value of pressure switch.The return pipe is choked by closing the stop-cock slowly. If the pres-sure switch is electrically connected the tripping pressure can be readfrom the manometer during signal output. In standard cases, the trippingpressure is 3.6 bar.

6. Set pump run time on time relay K29.The pump run time setting on time relay K29 is matched to the oil con-tent of the on-load tap-changer oil compartment and is undertaken in thefactory depending on the type of oil filter unit.Particular operating conditions may require a different pump run time tobe set.

7. Output a pulse on the motor-drive unit to check whether the oil filter unitautomatically starts when the motor-drive unit starts up.

Monitoring water content in insulating oil

After commissioning, the oil filter unit must be operated continuously for24 hours.

Monitor the drying properties of the combined filter cartridge by taking oilsamples at regular intervals.

Replace the combined filter when the measured water content of the insulat-ing oil exceeds 20 ppm. During commissioning and subsequent operation,check the water content and dielectric strength. Depending on the water

6.3.3



content established, proceed in accordance with flow chart [► 54]. Herethe standard procedure (water content and dielectric strength of the insulat-ing oil are both in the permissible range) is highlighted with bold lines.

Take oil samples for this standard procedure at the following intervals:▪ 1st oil sample 30 minutes after commissioning▪ 2nd oil sample 24 hours after commissioning▪ Further oil samples at 2-year intervals

To take an oil sample, proceed as follows:1. Switch off the OF 100 motor protective switch.2. Remove oil sample valve lock.3. Remove screw cap.4. Open oil sample valve.5. Take oil sample (take as much as needed by the lab).6. Close oil sample valve.7. Refit lock (with warning sign).8. Fit screw cap.9. Switch on OF 100 motor protective switch.

NOTICE Damage to the on-load tap-changer!Damage to the on-load tap-changer by actuating with damp oil.► Ensure that the silica gel breather for the on-load tap-changer oil con-

servator is in perfect condition!The breather prevents the ingress of dampness.

Record the oil temperature each time an oil sample is taken:

Regardless of the criteria related to water content, the dielectric strength ofthe insulating oil must be greater than 40 kV/2.5 mm as measured in accord-ance with DIN VDE 0370-1.

If one of the following factors is present, replace the filter cartridge:▪ Operating pressure greater than 3.6 bar at oil temperature of 20 °C▪ Water content after 24-hour filter operation not below 20 ppm▪ Dielectric strength after 24-hour filter operation < 40 kV/2.5 mm
