I:product description

TRSX series power supply lightning protection boxes are mainly used in meteorology, transportation, post and telecommunications, computer networks, electricity, residential distribution boxes, railways and other fields. Power supply lightning protection is divided into three levels: B, C, and D. According to the IEC (International Electrotechnical Commission) zoning lightning protection and multi-level protection theory, Level B lightning protection is the first level of lightning protection device and can be applied to main equipment in buildings. On the distribution cabinet: Class C lightning protection is a second-level lightning protection device, which is used in branch distribution cabinets of buildings; Class D lightning protection is a third-level lightning protection device, and the TRSX lightning protection box effectively suppresses radiation from AC power lines. to protect electrical equipment from induced lightning strikes and static electricity damage.

 

II:Main structure and working principle

The lightning protection box is connected in parallel to the front end of the protected equipment. Under normal operating voltage, the power supply lightning protection box is in a high resistance state and does not affect the normal operation of the circuit. When a line is struck by lightning and pulse overvoltage occurs, the power supply lightning protection box quickly turns on within a nanosecond, releasing the overvoltage to the earth. When the pulse overvoltage disappears, the power supply lightning protection box automatically returns to its high resistance value. status and does not affect the line power supply.
