Quando si verifica una sovratensione, il limitatore di sovratensione scollega immediatamente l'alimentazione. Questo tipo di protezione contro le sovratensioni is particularly intelligent, complex, and naturally more expensive, and is generally rarely used. This kind of protezione contro le sovratensioni 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 protezione contro le sovratensioni. 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 protezione contro le sovratensioni electrical circuit, which does not disconnect the power circuit when the protezione contro le sovratensioni is generated, but embeds the surge voltage, digesting and absorbing the kinetic energy of the protezione contro le sovratensioni. 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 protezione contro le sovratensioni are the live wire neutral-to-ground and the neutral-to-ground, that is, common mode suppression. Differential mode protezione contro le sovratensionis are used to embed, digest and absorb surge voltages between live and neutral. Likewise, common mode protezione contro le sovratensionis are also used to embed live-neutral-to-ground surge voltages. Generally speaking, for protezione contro le sovratensionis with lower requirements, the assembly of protezione contro le sovratensionis is sufficient, but common mode surge protection must be added in some places with stronger regulations.
