The traditional fault arc detector is generally arranged on a guide rail in a final-stage distribution box and arranged at the rear end of a circuit breaker or a leakage protector, and the fault arc detector is clamped on the guide rail in the distribution box and connected to a circuit to be protected between a circuit breaker and a load. With the increase of the types and the number of electric equipment, in order to avoid the damage of fault electric arcs to the electric equipment, the number of lines needing to use fault electric arc detectors is also increased continuously, the number of the fault electric arc detectors needing to be installed on corresponding distribution box guide rails is also increased, the accommodation capacity of the original distribution box is exceeded, and therefore a distribution box special for installing the fault electric arc detectors has to be additionally increased, the maintenance difficulty of the electric arc detectors and other electric equipment in the distribution box is increased, the maintenance cost is also increased, and therefore the customer acceptance is low. Meanwhile, the traditional fault arc detector is an independent product and comprises a power supply system, an arc inspection system, a bus system, an audible and visual alarm and the like, the cost of a single fault arc detector is higher, the total cost is increased along with the increase of the installation quantity of a distribution box, and the fault arc detector is also one of the reasons for low customer acceptance.
