Khi xảy ra điện áp đột biến, bộ bảo vệ đột biến sẽ ngắt nguồn điện ngay lập tức. Trường hợp này tăng Bảo vệ is particularly intelligent, complex, and naturally more expensive, and is generally rarely used. This kind of tăng Bảo vệ 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 tăng Bảo vệ. 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 tăng Bảo vệ electrical circuit, which does not disconnect the power circuit when the tăng Bảo vệ is generated, but embeds the surge voltage, digesting and absorbing the kinetic energy of the tăng Bảo vệ. 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 tăng Bảo vệ are the live wire neutral-to-ground and the neutral-to-ground, that is, common mode suppression. Differential mode tăng Bảo vệs are used to embed, digest and absorb surge voltages between live and neutral. Likewise, common mode tăng Bảo vệs are also used to embed live-neutral-to-ground surge voltages. Generally speaking, for tăng Bảo vệs with lower requirements, the assembly of tăng Bảo vệs is sufficient, but common mode surge protection must be added in some places with stronger regulations.
