Description

The outdoor type isolating switch
Technical field
The utility model relates to a kind of switching device for the high pressure electric line, relates in particular to a kind of outdoor type isolating switch.
Background technology
Isolating switch is a kind of switching device relatively simple for structure, is one of switching device important in electrical network, and its main application is to guarantee maintenance part in circuit and the isolation between electrified body, and idler circuit is closed in switch operating or the pass of carrying out circuit.Isolating switch drives plug-in strip by operating mechanism and divides, closes, and forms obvious circuit cut-off point after separating brake.Isolating switch can realize that electrical isolation (insulating power supply) has obviously visible enough large cut-off points, guarantees the safety of moving and overhauling.For example, used in a large number the outdoor type isolating switch on transformer station's outlet and 10KV circuit, can play to form when construction and in time isolate the effect of accident point when obvious cut-off point reaches in accident.
But due to technological reason, perhaps corrosive environment (air severe contamination in the electroplating industry district for example, thick air has a large amount of hydrochloric acid gas) impact, make outdoor type isolating switch plug-in strip fixation side the large tracts of land corrosion easily occur, even make the spring failure of gold utensil part, cause that thereby connecing empty discharge etc. easily causes the accidents such as circuit phase shortage, tripping operation, affects the normal electricity consumption of numerous clients and power supply reliability.
Summary of the invention
The purpose of this utility model is to provide a kind of outdoor type isolating switch, thereby to solve the problem that easily caused accidents such as connecing empty discharge circuit phase shortage, tripping operation after gold utensil partial spring that existing outdoor type isolating switch exists lost efficacy.
In order to address the above problem, the utility model provides a kind of outdoor type isolating switch, and it comprises: base is long plate shape; The first ceramic leg and the second ceramic leg vertically are fixed in respectively the two ends of described base; The first terminal block and the second terminal block are individually fixed in the upper end of described the first ceramic leg and the second ceramic leg; Plug-in strip, the fixation side of described plug-in strip and described the first terminal block are hinged by a movable axis, the active side of described plug-in strip and separable contact of described the second terminal block, the first end of described movable axis extends to the direction away from described plug-in strip; Draw ring is located at the active side of described plug-in strip; Spring is sheathed on described movable axis, and the first end of described spring is fixed in the first end of described movable axis, and the side that the other end of described spring is connected to described plug-in strip is used for making described plug-in strip and described the first terminal block close contact; Wherein, also comprise: the first device clamp and the second device clamp are individually fixed on described the first terminal block and the second terminal block; Binding post is located at the fixation side of described plug-in strip; The drainage wire is connected between described the first device clamp and described binding post.
According to a kind of preferred implementation of above-mentioned outdoor type isolating switch, wherein, described binding post is positioned at the side of described plug-in strip.
According to a kind of preferred implementation of above-mentioned outdoor type isolating switch, wherein, described drainage wire is the copper flexible cord.
The utility model is by utilizing the drainage wire that the plug-in strip part partly is connected with the first device clamp, to the drainage of plug-in strip fixation side, can reduce to flow through the electric current at plug-in strip gold utensil spring position, play prevention and control the effect that connects empty discharge, thereby avoid occuring the accidents such as circuit phase shortage, tripping operation, improve power supply reliability.
Description of drawings
Fig. 1 is the structural representation of the utility model preferred embodiment.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
Fig. 1 schematically shows the structure of the utility model preferred embodiment, as shown in the figure, the critical piece of this preferred embodiment probably comprises: plug-in strip 1, the first terminal block 21, the second terminal block 22, the first ceramic leg 31, the second ceramic leg 32, base 4 and drainage wire 5.Wherein, base 4 is long plate shape.The first ceramic leg 31,32 of the second ceramic leg are vertically to be fixed in respectively the two ends of base 4.The first terminal block 21, the second terminal block 22 are individually fixed in the upper end of the first ceramic leg 31, the second ceramic leg 32.The fixation side of plug-in strip 1 and the first terminal block 21 are hinged by a movable axis 130, and the active side of plug-in strip 1 is with second terminal block 22 is separable contacts, and the first end of movable axis 130 extends to the direction away from plug-in strip 1.Draw ring 14 is located at the active side of plug-in strip 1.Hook with brake pull-rod pulls draw ring 14 that the active side of plug-in strip 1 is separated with the second terminal block 22.Spring 13 is sheathed on movable axis 130, and the first end of spring 13 is fixed in the first end of movable axis 130, and the side that the other end of spring 13 is connected to plug-in strip 1 is used for making plug-in strip 1 and the first terminal block 21 close contacts.In the prior art, after spring 13 lost efficacy, just be difficult to guarantee again close contact between plug-in strip 1 and the first terminal block 21, connect empty discharge thereby easily cause.Occur for fear of the electric discharge phenomena that continue, the first terminal block 21 and the second terminal block 22 are fixed respectively one first device clamp 211 and the second device clamp 221.The fixation side of plug-in strip 1 arranges a binding post 11.Be connected with drainage wire 5 between the first device clamp 211 and binding post 11.Drainage wire 5 can reduce to flow through the electric current of spring 13, thereby prevention connects empty discharge.
