Nitrogen gas-insulated ring network cabinet

Abstract

The invention discloses a nitrogen gas-insulated ring network cabinet, which comprises a housing, wherein the left side of the housing is fixedly connected with a gas tank; the left side of the inner wall of the housing is fixedly connected with incoming line insulators; the left sides of the incoming line insulators sequentially penetrate through the housing and the gas tank and extend to the outside of the gas tank; circuit breakers are fixedly connected with two sides of the inner wall of the housing and the bottoms of the incoming line insulators; isolation switches are fixedly connected with the left side of the inner wall of the housing and the bottoms of the circuit breakers; the right side of each isolation switch is connected with an isolation knife; each isolation switch is movably connected with the corresponding circuit breaker through the corresponding isolation knife; outgoing line insulators are fixedly connected with the front surface of the inner wall of the housing and the bottoms of the isolation switches; the front surfaces of the outgoing line insulators penetrate through the housing and extend to the outside of the housing; and earthing switches are fixedly connected with the right side of the inner wall of the housing. The gas tank is filled with a nitrogen gas, so that the ring network cabinet is safer and more environment-friendly, and the problem that a traditional ring network cabinet is not environment-friendly is solved.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a nitrogen-insulated ring network cabinet. Background technique [0002] The ring network cabinet is a group of electrical equipment for transmission and distribution that is installed in a metal or non-metal insulated cabinet or made into an assembled interval ring network power supply unit. Its core part uses load switches and fuses. It has simple structure, small size, It has the advantages of low price, improved power supply parameters and performance, and power supply security. It is widely used in distribution stations and box-type substations in urban residential quarters, high-rise buildings, large public buildings, factories and enterprises, and other load centers. All network cabinets use sulfur hexafluoride gas to fill the air tank. Sulfur hexafluoride gas is an artificial inert gas. It is widely used in high and medium voltage power equipment at present, but sulfur hex...
