Low voltage switch cabinet Fundamentals training materials vacuum switchgear basics in actual use multiple vacuum breaker into the metal cabinet, composed of high voltage switchgear. In addition to the circuit breaker switchgear, also install play the role of isolation circuit isolating switch, from the security role of the grounding switch, measure or protection from the effects of current and voltage transformers, from the over-voltage arrester or protective effect RC absorber, but also install secondary circuit components and circuits, connection of cables or overhead lines can be used for relay into the cabinet, the switch cabinet as a function of a combination of a relatively independent power distribution equipment. In switching stations, transmission lines power plant substation, receives power user terminal substations are extensive use of various switchgear. About 10 years ago, equipped with less oil circuit breaker switchgear occupies almost a monopoly in the country, but with the rise of a vacuum circuit breaker, low oil switch refuse gradually back seat. Since 1993 made 'oil-free transformation' requirements since, also contributed to this trend, some provinces even banned the continued use less oil switch refuse in the city grid and key users of the station building, Dengfeng City High Low-voltage switchgear, the old station will gradually be replaced with a vacuum switch less oil switchgear. LCC HSBC cabinet details 110KV GIS system control cabinet sheet metal structure of the body frame thickness 2.5 front and back sides are open, the front door is a single door, low voltage switch cabinet how? , The back door of double doors, easy installation and maintenance. In addition to the front and rear door, the whole cabinet welding as a whole, good sealing effect in the two mounting plates connected by a hinge and cabinet Marina frame, low voltage switch cabinet installation, disassembly and convenient low voltage switch procurement, installation, operation and maintenance manual activities otherwise a mounting plate fixed to the sides of the cabinet at the side of the beam is installed, you can adjust the position of the front and rear, can be installed on both sides of the electrical device housing protection rating.: IP54. High and low voltage switchgear, learning Connaught Electrical and Mechanical, Dengfeng City, Henan conventional low voltage supplied by Connaught Electrical and Mechanical Equipment Co., Henan Xi Connaught Electrical Equipment Co.
