[0002] In traditional manufacturing processes, when batches of equipment need to be powered on for testing, this design aims to solve the problem of quickly powering on batches of equipment and reducing frequent secondary wiring in the power cabinet. The traditional method of wiring equipment for power-on requires wiring at both the power supply end and the power consumption end through OT terminals, which is time-consuming, labor-intensive, and inefficient. Furthermore, multiple secondary wirings in the power cabinet may expose electrical equipment and operating personnel to higher safety risks. Utility Model Content

[0003] This utility model provides a safety-protected power distribution cabinet, developed for rapid, safe, and efficient power connection during batch equipment commissioning in traditional equipment manufacturing. The cabinet features six independently controllable aviation sockets (expandable as needed), each equipped with a dual-color indicator light for clear monitoring of the circuit's operating status. Each aviation socket is equipped with an air switch; in case of a malfunction, each air switch protects the equipment in that circuit without affecting the power supply to other equipment being commissioned. The sockets have a quick-locking screw mechanism to prevent loosening and poor contact. It also boasts an IP67 protection rating, effectively providing waterproof, dustproof, and corrosion-resistant protection.

[0004] The technical solution of this utility model is: a safety protection power distribution cabinet, including multiple branch circuits with independent controllable aviation sockets, and each branch circuit is connected in series with a current detection module, an air switch and a red and green dual-color indicator light that can confirm the operating status of the branch circuit.

[0005] A molded case circuit breaker is connected in series on the main line to switch the power supply of the power distribution cabinet on and off.

[0006] The aviation socket, current detection module, air switch and molded case circuit breaker are all installed on the electrical mounting plate inside the power distribution cabinet;

[0007] The red and green dual-color indicator lights are installed on the cabinet door of the power distribution cabinet;

[0008] The power distribution cabinet is also equipped with an electromagnetic door lock to interlock the cabinet's locking mechanism and prevent misoperation.

[0009] Furthermore, a voltmeter is installed on the door of the power distribution cabinet to confirm the output voltage level of the power distribution cabinet.

[0010] Furthermore, the power distribution cabinet is also equipped with an emergency stop button switch that can forcibly output an electromagnetic door lock opening signal through the controller.

[0011] Furthermore, a universal transfer switch for voltmeter commutation measurement control is also installed on the cabinet door of the power distribution cabinet.

[0012] Furthermore, it is also equipped with industrial portable plug cables for connecting the power distribution cabinet and equipment for power transmission.

[0013] Furthermore, the industrial removable plug cable has an IP67 protection rating.

[0014] Furthermore, the aviation socket features a quick-locking spiral mechanism and has an IP67 protection rating.

[0015] Furthermore, there are at least 6 branch circuits.

[0016] The beneficial effects of this utility model are: during use, the device only requires wiring at the equipment end, and the power supply end can be directly plugged into the industrial fixed straight-body aviation socket in the power cabinet using an industrial mobile aviation plug cable. This device is easy to plug and unplug during use, facilitating equipment debugging, maintenance, and parts replacement. It is safe, efficient, convenient, and flexible in use.

[0017] The distribution cabinet has six independently controllable aviation sockets (expandable as needed), each equipped with a dual-color indicator light for clear visibility of the branch's operating status. Each socket is also equipped with an air switch; in case of a fault, each switch protects the equipment in that branch independently without affecting the power supply to other equipment being tested. The socket features a quick-locking screw mechanism to prevent loosening and poor contact. It also has an IP67 protection rating, effectively providing waterproof, dustproof, and corrosion-resistant protection.

[0018] This connection method improves work efficiency. To ensure safety, an electromagnetic lock is installed on the cabinet door. The cabinet door can only be opened for plugging and unplugging operations when each branch is not in operation, which is especially important in scenarios where equipment needs to be frequently replaced or debugged.
