Abstract
The utility model provides a novel circuit breaker used for a 10 kv inflatable cabinet, which comprises insulation supporting parts, a gas tank, a supporting part of a circuit breaker body, an outgoing line sleeve pipe and a connecting copper bar, wherein a vacuum arc-extinguish chamber is mounted inside each insulation supporting part, and the insulation supporting part is made of epoxy resin through the automatic pressure gelation process technology (APG), the three-phase insulation supporting parts provided with the vacuum arc-extinguish chambers are respectilvey fixedly mounted on the supporting part of the circuit breaker body, the supporting part of the circuit breaker body is fixed on the front plate of the gas tank through a screw, and sulfur hexafluoride gas is filled in gas tank. The novel circuit breaker used for the 10 kv inflatable cabinet has the advantages of compact structure, small volume, good insulating property, high product intensity and long service life, good switching stability and easy assembly.
Description
Technical field
The utility model relates to a kind of novel 10kV inflation cabinet circuit breaker, belongs to outdoor gas-filled type circuit breaker.
Background technology
Outdoor gas-filled type circuit breaker type ring main unit in the market generally is fixed on the bottom of casing, and strutting piece adopts metalwork or adopts epoxy resin spare, and size is bigger, causes bad, the fixing effect of built-in electrical insulation bad and cost is higher like this.
The utility model content
The purpose of this utility model is to provide a kind of novel 10kV inflation cabinet circuit breaker, reduces volume to reach, and improves the purpose of insulation property.
Novel 10kV inflation cabinet circuit breaker described in the utility model, comprise insulated support, gas tank, breaker body strutting piece, outlet sleeve pipe, connect copper bar etc., each insulated support inside is equipped with vacuum interrupter, this insulated support adopts epoxy resin to be made through automatic pressure gelation process technology (APG), the insulated support that three-phase is equipped with vacuum interrupter all is fixedly mounted on the breaker body strutting piece, on the header board of gas tank, gas tank inside is filled with sulfur hexafluoride gas to the breaker body strutting piece by screw.Be welded by argon arc welding around the gas tank, guarantee the sealing of gas tank.By connecting copper bar breaker body is connected with the outlet sleeve pipe of both sides in addition, the outlet sleeve pipe can connect external cable and realize distribution.
Novel 10kV inflation cabinet described in the utility model is with the advantage of circuit breaker: compact conformation, volume are little, good insulation preformance, and the product strength high life is long, and the switch good stability is easy to assemble.
Below in conjunction with drawings and Examples the utility model is further described.
