Description

A kind of gas-insulated compound electric apparatus
Technical field
The utility model relates to a kind of gas-insulated compound electric apparatus.
Background technology
In transformer station of enterprise, mountain area transformer station or power station, rural area, use traditional open type device for switching usually, because open type device for switching floor space is big, operation troubles is many, in above-mentioned transformer station transformation process, be that GIS (gas-insulated metal-enclosed combined electrical apparatus) replaces gradually at present.But the transformer station in above-mentioned area, because GIS needs a large amount of closed bus bar configuration of gas-insulated, price is relatively more expensive again, therefore, for cost consideration, the GIS switchgear is unsuitable for the megatechnics transformation of above-mentioned transformer station.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of high reliability, economizes ground and the low gas-insulated compound electric apparatus of cost.
For reaching above purpose, the utility model takes following technical scheme to be achieved:
A kind of gas-insulated compound electric apparatus, comprise that one is provided with first spherical shell of isolating ground unit, cylindrical shell that is provided with breaker unit, holds first sleeve pipe of first conductor and holds second sleeve pipe of second conductor, described spherical shell is arranged on the top of cylindrical shell breaker unit one side, and connect with the first sleeve pipe bottom, described first, second outside, sleeve pipe bottom is respectively equipped with first, second current transformer; It is characterized in that, also include one second in the described cylindrical shell and isolate ground unit that breaker unit one end is electrically connected with this second isolation ground unit; The other end and first is isolated ground unit and is electrically connected; Described second sleeve pipe is arranged on cylindrical shell second and isolates the top of ground unit one side; Described first, second isolated ground unit and is electrically connected with first, second conductor respectively.
In the such scheme, the described first isolation ground unit includes a linear pattern isolation earthing switch with second isolated location and is connected one three station detent mechanism; Described breaker unit includes a circuit breaker, wherein holds fixed contact, movable contact and arc control device, and described movable contact connects the operating mechanism of cylindricality outside; Described arc control device are self-energy arc-extinguishing chamber.
Gas-insulated compound electric apparatus of the present utility model is the switchgear that primary elements such as circuit breaker, isolating switch, earthed switch, current transformer are combined.For transformer station's tradition open type device for switching, its isolating switch and earthed switch all are closed in the metal shell, and operation is not subjected to the influence of environment.It adopts one pole sleeve pipe turnover wiring, link to each other with the air-insulated bus of the open type of transformer station, and the air-insulated layout of alternate maintenance open type, so save the area of 30%--40% than open type transformer substation switch electrical equipment on taking up an area of, maintenance cost reduces 30%.Owing to do not have the closed bus bar configuration of a large amount of gas-insulateds, so its price is more cheap than GIS.Thereby be embodied in take up an area of and price on the advantage of economy.
In addition, gas-insulated compound electric apparatus of the present utility model is the performance of transformer station to be done as a wholely consider, main feature is its compact and blocking design (multinomial function is concentrated in the unit), switchgear is to adopt the unit of limited quantity to satisfy required function and guarantee best-of-breed functionality at interval, and its blocking design can be satisfied the requirement that the existing transformer station of great majority transforms.
Description of drawings
Fig. 1 is a structure chart of the present utility model.Among the figure: 1 is first detent mechanism, and 2 is first sleeve pipe, and 3 is first conductor, 4 is first current transformer, 5 is spherical shell, and 6 is the first isolation ground unit, and 7 is cylindrical shell, 8 is breaker unit, 9 is second detent mechanism, and 10 is the second isolation ground unit, and 11 is second current transformer, 12 is second conductor, and 13 is second sleeve pipe.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As shown in Figure 1, the utility model comprises: spherical shell 5 and the first isolation ground unit 6 wherein; The breaker unit 8 and second isolated location 10 and the insulation gas filled cylindrical shell 7 are housed; First sleeve pipe 2 and second sleeve pipe 13 that holds second conductor 12 that hold first conductor 3.The described spherical shell 5 that comprises the first isolation ground unit 6 is arranged on the top of cylindrical shell 7 breaker units 8 one sides, and connects with the bottom of first sleeve pipe 2.The bottom arranged outside of first sleeve pipe 2 has first current transformer 4.Second sleeve pipe structurally is connected to the top of cylindrical shell 7 second isolated locations 10 1 sides by a ring flange; The bottom arranged outside of second sleeve pipe has second current transformer 11.
Conductor 3 and 12 can be connected the bus of electric power input and output by the binding post of sleeve pipe 2,13 upper ends respectively; Perhaps be connected on other electric device according to practical use.The function of current transformer 4,11 is to transmit information to measuring instrument, instrument or current collection protection, control device, makes measurement, protection and control device and high voltage isolated simultaneously.
In the utility model, include a linear pattern isolation earthing switch in the first isolation ground unit 6, its moving contact realizes isolating each station branch, the combined floodgate of ground unit 6 by detent mechanism 1 actuating of one three station.The structure that second structure and first of isolating ground unit 10 is isolated ground unit 6 is identical, and linear pattern isolation earthing switch moving contact wherein realizes isolating each station branch, the combined floodgate of ground unit 10 by the actuating of another three stations detent mechanism 9.
