[0002] At present, the main technologies for electrical fire prevention of power equipment are circuit breakers and leakage protection devices, and electrical fires are still the main source of fires. The mainstream circuit breaker protection can only protect against short circuits, but is powerless against arc faults, which have less energy but are also fire hazards, and cannot be discovered in time when they fail. On the other hand, there are a lot of false operations in leakage protection, which makes it impossible for power users to work normally. Therefore, arc fault detection and alarm protection devices are used to provide real-time protection against arc faults;
[0003] When installing the existing arc fault identification device, a large number of bolts and nails are needed to fix it. After long-term use, the bolts and nails will produce rust spots, which will increase the burden on the dismantling personnel when the arc fault identification device needs to be dismantled.
