Lorsqu'une surtension se produit, le parasurtenseur déconnecte immédiatement l'alimentation électrique. Ce genre de parasurtenseur is particularly intelligent, complex, and naturally more expensive, and is generally rarely used. This kind of parasurtenseur 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 parasurtenseur. 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 parasurtenseur electrical circuit, which does not disconnect the power circuit when the parasurtenseur is generated, but embeds the surge voltage, digesting and absorbing the kinetic energy of the parasurtenseur. 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 parasurtenseur are the live wire neutral-to-ground and the neutral-to-ground, that is, common mode suppression. Differential mode parasurtenseurs are used to embed, digest and absorb surge voltages between live and neutral. Likewise, common mode parasurtenseurs are also used to embed live-neutral-to-ground surge voltages. Generally speaking, for parasurtenseurs with lower requirements, the assembly of parasurtenseurs is sufficient, but common mode surge protection must be added in some places with stronger regulations.
