TRSX series power lightning protection box is mainly used for weather, transportation, post and telecommunications,
computer network, power distribution box, residential, railway and other fields.Power supply prevents thunder B,C,D, are
the three levels, according to the IEC (international electrotechnical commission) partition of lightning protection, multi-level
protection theory, class B belongs to the first level of lightning protection lightning protection device, can be applied to
building the ark of the main distribution:class C belongs to the second level of lightning protection lightning protection device,
applied to the structure of the shunt power distribution cabinet; D belongs to the third level of lightning protection lightning
protection device,TRSX lightning protection box effectively restrain the road from the ac power supply cord into the induction
lightning waves, and electrostatic damage to protect electrical equipment from lightning strike.
Structure and Principle
Lightning protection box in parallel to the protected equipment front-end, under the condition of normal operating voltage,
power supply lightning protection box in a high impedance state, does not affect the normal work of the circuit. When there is
pulse surge line lightning strike, power lightning protection box in the nanosecond time conduction, quickly put the overvoltage
of diarrhea in the earth, when the pulse over-voltage disappears, power lightning protection box and automatic recovery to a
high resistance state, does not affect the line power supply.
