Como funcionam os dispositivos de proteção contra surtos?

Quando ocorre um surto de tensão, o estabilizador desconecta imediatamente a fonte de alimentação. Este tipo de protetor de surto is particularly intelligent, complex, and naturally more expensive, and is generally rarely used. This kind of protetor de surto 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 protetor de surto. 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 protetor de surto electrical circuit, which does not disconnect the power circuit when the protetor de surto is generated, but embeds the surge voltage, digesting and absorbing the kinetic energy of the protetor de surto. 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 protetor de surto are the live wire neutral-to-ground and the neutral-to-ground, that is, common mode suppression. Differential mode protetor de surtos are used to embed, digest and absorb surge voltages between live and neutral. Likewise, common mode protetor de surtos are also used to embed live-neutral-to-ground surge voltages. Generally speaking, for protetor de surtos with lower requirements, the assembly of protetor de surtos is sufficient, but common mode surge protection must be added in some places with stronger regulations.
