power level explosion-proof box for lightning protection
Characteristics:
1.Digitalization, anti-explosion, anti-dust, anti-water, anti-corrosion, anti-flaming
2.Superior performance, small volume, modulization, excellent airtight property, attractive appearance
3.Safe and reliable in use, easy and simple in installing
4.Telesingnalling. Have installed the telesignalling port, user can monitor the operating state through the monitoring interface; avoid the damage caused by no monitoring.
5.Sparkgap protection, pass 10/350us test
6.Low residual voltage, large current capacity, quick response
7.Guide line connection status indicator
8.Recover by itself, do not affect normal power supply
Application:
In the frond part protection of the power system, install among the LPZ0, LPZ1, and LPZ2 surfaces, bleed part of the energy, and limit the overvoltage in a certain range.
Operating Principle:
Under normal circumstance, the SPD is in a high impedance condition, when the power grid line suffers the direct, indirect lightning stock or other instant overvoltage, in nanoseconds, the SPD can realize the low resistance conducting state, bleed the instant energy into the earth, meanwhile, limits the overvoltage in a protection level. When the instant overvoltage disappear, SPD return into the high impedance condition, thus do not affect the normal operation of the power grid line.
