The Working Principle and Classification of Surge Protector
Ⅰ. The surge protection device working principle
Surge protection device is an indispensable device in lightning protection of electronic equipment. In the past, it was often called "lighting protector" or "over-voltage protector", abbreviated as SPD. The function of surge protection device is to limit the instantaneous over-voltage of the power line and signal transmission line to the voltage range that the equipment or system can withstand, or to drain the powerful lightning into the ground to protect the equipment or system from being damaged by impact.
The type and structure of surge protection device by CHENZHU, a reliable company specializing in safety and automation system vary for different purposes, but it should contain at least one nonlinear voltage limiting element.
Ⅱ. Types of surge protection device
Surge protection device is classified according to its working principle:
The categories of surge protection device by use are:
- ACpower surge protection device, DC power protection device, switch type power protection device and so on.
