Когато възникне пренапрежение, защитата от пренапрежение незабавно изключва захранването. Този вид защита от пренапрежение is particularly intelligent, complex, and naturally more expensive, and is generally rarely used. This kind of защита от пренапрежение is generally made of current sensor. The composition of the control board and the lock. The purpose of the current sensor is to detect whether the grid voltage has fluctuations in the защита от пренапрежение. When the control board loads the surge voltage data signal of the current sensor, the lock is operated immediately, as the conduction of the actuator control circuit. There is another защита от пренапрежение electrical circuit, which does not disconnect the power circuit when the защита от пренапрежение is generated, but embeds the surge voltage, digesting and absorbing the kinetic energy of the защита от пренапрежение. This type of circuit is usually placed inside a circuit board, such as a switching power supply circuit. Surge protector class 1. Cross-border marketing is between the live wire and the neutral wire, that is, the differential mode suppression power circuit. The second and third level jumpers of the защита от пренапрежение are the live wire neutral-to-ground and the neutral-to-ground, that is, common mode suppression. Differential mode защита от пренапрежениеs are used to embed, digest and absorb surge voltages between live and neutral. Likewise, common mode защита от пренапрежениеs are also used to embed live-neutral-to-ground surge voltages. Generally speaking, for защита от пренапрежениеs with lower requirements, the assembly of защита от пренапрежениеs is sufficient, but common mode surge protection must be added in some places with stronger regulations.
