Dema ku voltaja hilkişînê çêbibe, parêzvana hilavêtinê tavilê dabînkirina hêzê qut dike. Ev cure parêzvana derzê is particularly intelligent, complex, and naturally more expensive, and is generally rarely used. This kind of parêzvana derzê 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 parêzvana derzê. 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 parêzvana derzê electrical circuit, which does not disconnect the power circuit when the parêzvana derzê is generated, but embeds the surge voltage, digesting and absorbing the kinetic energy of the parêzvana derzê. 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 parêzvana derzê are the live wire neutral-to-ground and the neutral-to-ground, that is, common mode suppression. Differential mode parêzvana derzês are used to embed, digest and absorb surge voltages between live and neutral. Likewise, common mode parêzvana derzês are also used to embed live-neutral-to-ground surge voltages. Generally speaking, for parêzvana derzês with lower requirements, the assembly of parêzvana derzês is sufficient, but common mode surge protection must be added in some places with stronger regulations.
