equal potential in the joint between different zones. The protected

zone divided into several lightningproof zones (LPZ).

LPZ0A zone: all objects in this zone may be strike by direct lightning

and carry full lightning current, electromagnetic field strength has

no attenuation.

LPZ0B zone: withi n the relevant scope of selected grounder radius

in this lightning-proof zone, the objects may not be strike by direct

lightning, but electromagnetic field strength has no attenuation.

LPZ1 zone: the objects in this zone are impossibly strike by lighting,

lighting current on conductors and electromagnetic field strength

are attenuated, the attenuation degree is determined by field

solutions in the buildings.

devi ce, to limit surge current, overvoltage,

over-current occurred in the power system

due to some reasons, working in the system

of AC 50Hz, rated voltage 380V and bel ow

mounted on 35mm railway, compared with

normal combination of fuse + SPD module,

there has following advantages:

Residual voltage reduce more than 50%, for

normal combination, fuse body and connected

conductor have inductance, and will result

in residual voltage, but MBD1-R series

almos t has no residual voltage at this case,

therefore it can get better result of protecting

equipment.

Easy installation, saving space, saving

Quicker response speed, comprehensive

performance being improved.

Better N point: no matter which step of circuit,

there has shortest distance for discharging

surge current, residual voltage decrease more.

Explanation Of SPD Technical Term

Voltage Switching Type SPD

SPD that it shows high impedance when there has no surging, and

becomes low impedance while surging voltage occurs. Voltage

switching type SPD generally composed of discharging gap, gas

discharging tube, thyratron (silicone controllable rectifier) and

three-ending bidirectional silicone switching element. Sometimes

it also call "short circuit type SPD" .

Voltage Limiting Type SPD

SPD that it shows high impedance when there has no surging, but

the impedance will decrease gradually while surging current and

voltage rise up. Common non-linear element: piezoresistance,

and clamping diode. Sometimes it also call "Clamping SPD".

Combination SPD

SPD constructed of voltage switching and voltage limiting elements.

The characteristics curve can take on the characteristics of voltage

switching or limiting type, or both.

Modes Of Protection

Protective element of SPD can be connected between phase line

to phase line (L-L), phase line to earth (L-PE), phase line to neutra l

line (L-N), neutral line to earthing line (N-PE) or their combination.

These connections call protection modes.

SPD Disconnector

The device that isolates SPD from power supply network

(interior and / or outer).

Nominal Discharge Current

The 8/20 wave current peak that passing by SPD, used for grading

SPD under class II test, or prospective treatment of SPD class I,

II test.

Explanation Of SPD Technical Term

Voltage Switching Type SPD

SPD that it shows high impedance when there has no surging, and

becomes low impedance while surging voltage occurs. Voltage

switching type SPD generally composed of discharging gap, gas

discharging tube, thyratron (silicone controllable rectifier) and

three-ending bidirectional silicone switching element. Sometimes

it also call "short circuit type SPD" .

Voltage Limiting Type SPD

SPD that it shows high impedance when there has no surging, but

the impedance will decrease gradually while surging current and

voltage rise up. Common non-linear element: piezoresistance,

and clamping diode. Sometimes it also call "Clamping SPD".

Combination SPD

SPD constructed of voltage switching and voltage limiting elements.

The characteristics curve can take on the characteristics of voltage

switching or limiting type, or both.

Modes Of Protection

Protective element of SPD can be connected between phase line

to phase line (L-L), phase line to earth (L-PE), phase line to neutra l

line (L-N), neutral line to earthing line (N-PE) or their combination.

These connections call protection modes.

SPD Disconnector

The device that isolates SPD from power supply network

(interior and / or outer).

Nominal Discharge Current

The 8/20 wave current peak that passing by SPD, used for grading

SPD under class II test, or prospective treatment of SPD class I,

II test.
