ເມື່ອເກີດແຮງດັນໄຟຟ້າ, ເຄື່ອງປ້ອງກັນກະແສໄຟຟ້າຈະຕັດການເຊື່ອມຕໍ່ການສະຫນອງພະລັງງານທັນທີ. ປະເພດນີ້ ເຄື່ອງປ້ອງກັນກະແສໄຟຟ້າ is particularly intelligent, complex, and naturally more expensive, and is generally rarely used. This kind of ເຄື່ອງປ້ອງກັນກະແສໄຟຟ້າ 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 ເຄື່ອງປ້ອງກັນກະແສໄຟຟ້າ. 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 ເຄື່ອງປ້ອງກັນກະແສໄຟຟ້າ electrical circuit, which does not disconnect the power circuit when the ເຄື່ອງປ້ອງກັນກະແສໄຟຟ້າ is generated, but embeds the surge voltage, digesting and absorbing the kinetic energy of the ເຄື່ອງປ້ອງກັນກະແສໄຟຟ້າ. 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 ເຄື່ອງປ້ອງກັນກະແສໄຟຟ້າ are the live wire neutral-to-ground and the neutral-to-ground, that is, common mode suppression. Differential mode ເຄື່ອງປ້ອງກັນກະແສໄຟຟ້າs are used to embed, digest and absorb surge voltages between live and neutral. Likewise, common mode ເຄື່ອງປ້ອງກັນກະແສໄຟຟ້າs are also used to embed live-neutral-to-ground surge voltages. Generally speaking, for ເຄື່ອງປ້ອງກັນກະແສໄຟຟ້າs with lower requirements, the assembly of ເຄື່ອງປ້ອງກັນກະແສໄຟຟ້າs is sufficient, but common mode surge protection must be added in some places with stronger regulations.
