[0002] The power distribution cabinet technology of power engineering is an important field in the power system. The distribution cabinet is usually composed of a cabinet, circuit breaker, disconnector, mutual inductor, electric meter, etc. The cabinet is the basis of the distribution cabinet, which is used to install electrical components and protect the inside of the equipment. The electrical principle of the distribution cabinet mainly involves the measurement and control of parameters such as current, voltage, and power factor. By using mutual inductors, ammeters, voltmeters and other equipment, these electrical parameters can be monitored in real time and adjusted and controlled as needed. In power engineering, the application of distribution cabinets is very extensive. They are installed in various power facilities, such as substations, power plants, industrial plants, etc., to distribute electrical energy to various electrical equipment. At the same time, the distribution cabinet also undertakes important tasks such as protecting circuits and preventing the spread of electrical faults.
