Како функционираат уредите за заштита од пренапони?

Кога ќе се појави пренапонски напон, заштитникот од пренапони веднаш го исклучува напојувањето. Овој вид на заштитник за пренапони is particularly intelligent, complex, and naturally more expensive, and is generally rarely used. This kind of заштитник за пренапони 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 заштитник за пренапони. 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 заштитник за пренапони electrical circuit, which does not disconnect the power circuit when the заштитник за пренапони is generated, but embeds the surge voltage, digesting and absorbing the kinetic energy of the заштитник за пренапони. 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 заштитник за пренапони are the live wire neutral-to-ground and the neutral-to-ground, that is, common mode suppression. Differential mode заштитник за пренапониs are used to embed, digest and absorb surge voltages between live and neutral. Likewise, common mode заштитник за пренапониs are also used to embed live-neutral-to-ground surge voltages. Generally speaking, for заштитник за пренапониs with lower requirements, the assembly of заштитник за пренапониs is sufficient, but common mode surge protection must be added in some places with stronger regulations.
