[0003] The existing Chinese patent with authorization announcement number CN220822277U discloses a safety protection power box; it includes a cabinet body, a cabinet door and a control device, the control device includes a power socket, a control transformer, a rail, a circuit breaker, a control PLC, a terminal block and a heat dissipation component. When in use, the power socket is used for overall power on-off control, the control transformer is used to control the PLC working power supply, and indicator lights and control buttons are installed on the cabinet door for manual control and automatic control operations. Before use, the corresponding circuit connections are made according to the circuit diagram to form a control system. When the equipment is in use, only a single electrical cabinet is set up to achieve control, which reduces costs. At the same time, control by controlling the PLC can obtain better stability, which will also be more conducive to automatic control use, thereby optimizing the equipment volume during use.
