Background technology
Bus is as the element that collects, distributes and transmit electric energy, it is indispensable part in high voltage electric appliance, and the three-phase non-segregated bus great majority of applying in 252kV GIS High-Voltage Electrical Appliances are all shorter, between interval and interval, need bus to be connected when long, just need a lot of root buses to connect and could meet, cost compare is high.In order to fall this cost, reduce the quantity of shell flange face, insulation basin, conductor and contact base, need to use two insulating supportings that the length of 252kV GIS three-phase non-segregated bus is lengthened.
Through the retrieval of prior art is found, in existing 252kV GIS three-phase non-segregated bus version, there is the length that uses the structure of insulating supporting to lengthen bus, but insulating part is to be all fixed on housing, between three-phase conductor, naked supports, so just need to increase boss fixed insulation in inner walls and support, make inner walls complex structure.High pressure industry there is no the structure that uses insulating supporting between three-phase conductor at present, if when needing the length of single bus to accomplish more to grow and not needing inner walls to manufacture complexity, just need to use the structure that uses insulating supporting between three-phase conductor, the distortion of constraint three-phase conductor, further lengthens the length of bus.
Utility model content
For the defect existing in prior art, the purpose of this utility model is to provide a kind of three-phase non-segregated bus for 252kV high-voltage switch gear, make to use between the three-phase conductor of high-voltage switch gear the common box bus of insulating supporting, meet bus housing being simplified and the requirement that extends bus length in GIS gas-insulated metal enclosed switchgear.
For achieving the above object, the utility model adopts following technical scheme:
For a three-phase non-segregated bus for 252kV high-voltage switch gear, comprise housing, the two ends of described housing are respectively equipped with disc insulator, and described disc insulator and described housing are connected and fixed;
In described housing, be provided with conductive component, described conductive component comprises the long conductor that three-phase is parallel to each other, one end of every phase long conductor is connected with a disc insulator by contact base, and the other end of every phase long conductor is connected with another disc insulator by fixed conductor; Wherein, described long conductor adopts the structure of pegging graft to be connected with described contact base, and described long conductor and described fixed conductor are connected and fixed;
Between described three-phase long conductor, be also provided with at least one Y shape insulating carriage, described Y shape insulating carriage and described three-phase long conductor are perpendicular, and three ends of described Y shape insulating carriage are connected and fixed with three-phase long conductor respectively.
