Abstract
The utility model relates to a capacitive voltage-sharing dry type insulated bus, an insulated part is composed of wound epoxy resins impregnating crepe paper and capacitance pressure equalizing screens arranged in an epoxy resins impregnating crepe paper layer at intervals. A protective layer arranged at the outermost layer adopts a heat-shrinkable pipe or a clad pipe composed of the heat-shrinkable pipe and a metal pipe. Frequent single phase earth contact and interphase short circuit are avoided in operation. The utility model has the characteristics of safety, reliability, uniform surface field intensity distribution, strong corona resistant performance and wide application range. The utility model not only suitable for a substation with compact structure, but also suitable for being made into various geometric shapes to satisfy the requirements of an installation environment. In the manufacture process, a generatrix does not need pouring mould, and the manufacturing cost is reduced greatly.
Description
Technical field
The utility model relates to a kind of electric component, particularly a kind of capacitor voltage equalizing type dry insulation bus.
Background technology
Existing bare bus bar, in use, especially for the compact transformer station of structure, single-phase earthing and phase fault accident take place because of the phase insulation of bus is weak in regular meeting, and reliability is relatively poor; It is dumb that the metal-air enclosed busbar is used, and it is narrow to be suitable for current range, and cable is the cost height then, and can not be according to installation environment and changes shape, and it is convenient inadequately to use.
Summary of the invention
The purpose of this utility model be to provide a kind of safe and reliable, along even, the anti-corona ability of face field strength distribution capacitor voltage equalizing type dry insulation bus strong, applied widely.
Technology solution of the present utility model is: a kind of capacitor voltage equalizing type dry insulation bus, comprise conductor, insulating barrier and overcoat, the two ends that it is characterized in that bus-bars conductor are connected with board-like terminal, the insulating barrier of conductor outside adopts epoxy resin impregnated insulating paper to be entwined, the capacitor voltage equalizing screen is set in the insulating barrier at both ends at interval, the insulating barrier outermost layer is provided with the ground connection electric screen, ground connection electric screen peripheral hardware overcoat.Described overcoat is heat-shrinkable tube or the multiple tube that is made of heat-shrinkable tube and metal tube.The overcoat at bus two ends is outer can be provided with full skirt.Owing to adopted said structure, make this bus have along the strong characteristics of even, the anti-corona ability of face field strength distribution, safe and reliable, the transformer station that it is adapted at compact conformation uses.This bus is made various geometries easily simultaneously, satisfies the needs of installation environment.
Characteristics of the present utility model are: safe and reliable, the generation that can stop frequently to take place single-phase earthing and phase fault accident in service, even along the face field strength distribution, anti-corona ability is strong, applied widely, the transformer station that both had been fit to compact conformation uses, and can make various geometries again, satisfies the needs of installation environment.
Description of drawings
Fig. 1 is the partial structurtes schematic diagram of the utility model bus;
Fig. 2 is the partial structurtes schematic diagram of another embodiment of the utility model;
Embodiment
Be described further below in conjunction with accompanying drawing:
The bus that Fig. 1 provides is adapted at indoor use, because the two ends symmetry of bus, the therefore structure of only drawing bus one end.The conductor 1 of bus is copper rod or copper pipe, also can adopt aluminum, and the two ends of copper rod are welded with tabular binding post 2.Be wound with epoxy resin impregnated insulating paper on conductor, constitute solid insulating layer 3, it bears conductor and reaches alternate full voltage over the ground.Capacitor voltage equalizing screen 4 is set in the insulating barrier at both ends at interval, and how much what capacitor voltage equalizing shielded determines according to electric pressure.The insulating barrier outside is provided with ground connection electric screen 5, and the outer overcoat 6 that is provided with of ground connection electric screen is a heat-shrinkable tube.The use of heat-shrinkable tube has realized the no mould manufacturing of bus.The geometry of simultaneously all right conversion bus is converted into required shape, to satisfy the needs of installing.
The bus that Fig. 2 provides is adapted at outdoor use, and the overcoat at the bus two ends is outside equipped with full skirt 7, and overcoat is by heat-shrinkable tube and be located at its outer metal tube or multiple tube that metal hose constitutes, and is not shown.Other structure is identical with scheme 1.
Claims (3)
1, a kind of capacitor voltage equalizing type dry insulation bus, comprise conductor, insulating barrier and overcoat, the two ends that it is characterized in that bus-bars conductor are connected with board-like terminal, the insulating barrier of conductor outside adopts epoxy resin impregnated crimped paper to be entwined, the capacitor voltage equalizing screen is set in the insulating barrier at both ends at interval, the insulating barrier outermost layer is provided with the ground connection electric screen, ground connection electric screen peripheral hardware overcoat.
2, capacitor voltage equalizing type dry insulation bus according to claim 1 is characterized in that described overcoat is heat-shrinkable tube or the multiple tube that is made of heat-shrinkable tube and metal tube.
3, capacitor voltage equalizing type dry insulation bus according to claim 1 is characterized in that the overcoat at described bus two ends can be provided with full skirt outward.
