عند حدوث زيادة في الجهد ، يقوم واقي زيادة التيار بفصل مصدر الطاقة على الفور. هذا النوع من حامي الطفرة is particularly intelligent, complex, and naturally more expensive, and is generally rarely used. This kind of حامي الطفرة 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 حامي الطفرة. 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 حامي الطفرة electrical circuit, which does not disconnect the power circuit when the حامي الطفرة is generated, but embeds the surge voltage, digesting and absorbing the kinetic energy of the حامي الطفرة. 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 حامي الطفرة are the live wire neutral-to-ground and the neutral-to-ground, that is, common mode suppression. Differential mode حامي الطفرةs are used to embed, digest and absorb surge voltages between live and neutral. Likewise, common mode حامي الطفرةs are also used to embed live-neutral-to-ground surge voltages. Generally speaking, for حامي الطفرةs with lower requirements, the assembly of حامي الطفرةs is sufficient, but common mode surge protection must be added in some places with stronger regulations.
