Product Description
HXGN-12 series switchgear (ring main unit) box-type fixed AC metal-enclosed ring main unit switchgear (referred to as ring main unit) is used in the power supply system for breaking load current, short-circuit current and closing short-circuit current. The ring network cabinet is equipped with a vacuum load switch, and the operating mechanism is a spring operating mechanism, which can be operated manually or electrically. The grounding switch and the isolation knife are equipped with manual mechanisms, which are strong in complete sets, small in size, and non-combustible in the ring network cabinet, and have reliable "five-proof" functions.
The ring main unit is used in the power distribution system of AC 10KV and 50Hz. It is widely used in urban power grid construction and renovation projects, industrial and mining enterprises, high-rise buildings and public facilities. in the substation.
The skeleton of HXGN-12 ring network switchgear is assembled from domestic and foreign technical profiles; the overall structure of the cabinet is firm, the top of the cabinet is the busbar room, and the front of the busbar room is the instrument room, which is separated by metal plates. The middle and upper part of the body is the installation position of the load switch, and the lower part is the installation position of the cable inlet and outlet lines and other components (such as current and voltage transformers); there are metal partitions between the cabinets and bushings between the busbar compartments to ensure that each Safe operation of the power supply unit; doors and terminal seals are sprayed with electrostatic powder. The above treatment methods and materials are used to make the switchgear shell have strong anti-corrosion performance; the cabinet body has a complete device to prevent electrical misoperation; the cabinet body is small in size, occupies a small area, compact in structure, safe and reliable; The protection level of the shell reaches IP4x; This ring network cabinet complies with the relevant standards of IEC420 and GB3906-91.
