Obviously, a surge backup protector is not the same as a surge protector.
(SPD) 不能切断工频短路电流时，过电流保护电器动作，把浪涌保护器 (SPD) 从并联线路中断开，使 SPD 不会引起过热而导致火灾、爆炸等事故，同时可保证电源的持续供电。 Functionally speaking, the surge backup protector selectively cuts off the passing power frequency current and lightning current. Generally, if the disconnector fails, when the surge protector (SPD) cannot cut off the power frequency short-circuit current, the overcurrent protection The electrical appliances operate to disconnect the SPD from the parallel line, so that the SPD will not cause overheating and cause fire, explosion and other accidents, and at the same time can ensure continuous power supply.
SPD 有雷电流通过时，这个外置脱离器不会出现误脱扣，使电气设备防雷始终处于有效状态。 At the same time, when the SPD has a lightning current passing through, this external disconnector will not trip by mistake, so that the lightning protection of electrical equipment is always in an effective state.
In short, the surge backup protector protects the surge protector to a certain extent and adds a safety insurance to the entire circuit. SPD 监测时安全断电。 It also facilitates the need to safely power down when monitoring SPD . SPD 和电路增加安全性。 Generally, the surge backup protector is installed at the front of the surge protector to increase the safety of the SPD and the circuit.
Surge protector is a device used to protect electrical and electronic equipment from being damaged by lightning electromagnetic pulses. It can be said that it is the "protector" of many modern high-tech products and protects the safety of circuits and equipment during lightning strikes.
