Description

Technical Field

[0001] The utility model relates to the technical field of arc protection, and more specifically, to an arc protection device. Background Art

[0002] In current life, arc protection device is a new type of protection developed in recent years with the development of optoelectronic technology. It takes current and arc as the main criteria. Compared with traditional protection, it adds arc as a criterion. It is suitable for 35 kW substations and medium and low voltage switch cabinets. It mainly solves medium and low voltage bus failures caused by arc short circuits. Arc protection means that the power system can cause arc due to various short circuit reasons. The arc will burst at a speed of 300 meters per second and destroy any material on the way. As long as the system is powered on, the arc will always exist. For example, an arc protection device described in the prior art publication number (CN114221303A) is installed and fixed in a specified position through a fixing plate and a fixing hole, and the working line is connected to the circuit board. When the equipment is working, when arc light is transmitted from the working line, the information transmission module on the circuit board transmits the arc light information to the arc light sensor. The arc light sensor senses the appearance of the arc light, and the arc light sensor transmits the information to the arc light signal conversion module.

[0003] When the above-mentioned device is working, by setting a spring limit structure and an unlocking mechanism, the entire equipment can be quickly installed and disassembled, and the traditional screw connection method is broken away, which is beneficial to practical application and operation. However, its structure is relatively complex. When the protector is disassembled, the internal movable plate is easily offset when the pull ring is pulled, making it inconvenient to disassemble the protector. Utility Model Content
