The fan distribution box can be used in the power supply of equipment, which can reasonably distribute the electric energy, so as to facilitate the opening and closing operation of the circuit. Among the safety protection levels, the fan distribution box has a higher safety protection level, and people can directly see the conduction state displayed on the circuit. At ordinary times, the main purpose is to cooperate with the use of the fan. For some other equipment that needs electricity, the fan distribution box can supply power to it. In the distribution box equipment, there is also a start stop button, so that the equipment that uses electricity can be effectively started and stopped. If the equipment fails during the work, the fan distribution box can provide power to it, The fan distribution box can check the equipment through the signal indicator, check whether it is in normal operation, and protect the equipment using electricity.
