High voltage complete distribution equipment, also known as high-voltage complete distribution cabinet, is a high-voltage distribution equipment supplied by a manufacturer and assembled on site. This device divides the main electrical circuit into multiple unit circuits, with each unit integrating circuit breakers, isolation switches, transformers, and protection control equipment in a single cabinet. Multiple switch cabinets can be combined to form the distribution system of power plants and substations.
It can be divided into metal enclosed, metal enclosed armored, metal enclosed box, SF6 enclosed combination electrical appliances and other types according to structural characteristics. According to the installation method of the circuit breaker, it can be divided into fixed and handcart types, and according to the installation environment, it can be divided into indoor and outdoor types. The device is equipped with a "five prevention" interlocking function, which prevents misoperation through mechanical or electromagnetic locking, ensuring safe operation.
