Rail transit lightning protection
Surge protector, also called lightning arrester, is an electronic device that provides safety protection for various electronic equipment, instruments and communication lines. When a sudden current or voltage is suddenly generated in the electrical circuit or communication line due to external interference, the surge protector can conduct shunt in a very short time, thereby avoiding the damage of the surge to other equipment in the circuit.

Rail transit lightning protection

working principle:

Surge protection device (Surge protection Device) is an indispensable device for lightning protection of electronic equipment. It was often called
"Surge arrester" or "overvoltage protector" is abbreviated as SPD. The function of the surge protector is to limit the instantaneous overvoltage that penetrates into the power line and signal transmission line within the voltage range that the equipment or system can withstand, or to Lightning current leaks to the ground to protect the protected equipment or system from damage.
The type and structure of the SPD are different for different purposes, but it should include at least one non-linear voltage limiting element. The basic components used in surge protectors are: discharge gap, gas-filled discharge tube, varistor, suppression diode and choke coil.
