P+F Pepperl+Fuchs surge protection, explosion-proof like a cow

The basic components of P+F Pepperl+Fuchs surge protector include: discharge gap, gas-filled discharge tube, varistor, suppression diode and choke coil. Surge protectors are used for overvoltage protection, such as lightning strikes, operating overvoltages, etc., through surge absorbers to limit the voltage range and protect the equipment. The main function of the safety barrier is to limit the energy on the loop to make it lower than the energy for igniting explosive dangerous objects to prevent explosion.

P+F Pepperl+Fuchs surge protector is also called "lightning arrester" or "overvoltage protector" in English abbreviated as SPD. The function of the surge protector is to limit the instantaneous overvoltage that enters the power line and signal transmission line within the voltage range that the equipment or system can withstand, or to leak strong lightning current into the ground to protect the protected equipment or system from Damaged by impact. Surge is to limit the input and isolate the large current and high voltage from the field; the safety barrier is to limit the output, which converts the non-intrinsically safe signal in the cabinet into intrinsically safe signal output. A surge protector is a device that protects the power grid from lightning strikes and large current surges. The function of the surge protector is to limit the instantaneous overvoltage that enters the power line and signal transmission line within the voltage range that the equipment or system can withstand, or to leak strong lightning current into the ground to protect the protected equipment or system from Damaged by impact. The type and structure of a surge protector are different for different purposes, but it should at least contain a non-linear voltage limiting element.
