Abstract

The invention relates to the technical field of power equipment, in particular to an insulating cover. The insulating cover comprises a cover body, a wire inlet, a three-station disconnecting link acting cavity, an insulating pull rod, a vacuum arc extinguishing cavity and a wire outlet; the wire inlet is positioned at the top of the cover body; the three-station disconnecting link acting cavity is positioned on the middle part of the cover body; and the insulating pull rod, the vacuum arc extinguishing cavity and the wire outlet are positioned at the bottom of the cover body. By adopting a solid medium insulating form, the potential safety hazard is released; and the vacuum arc extinguishing cavity is connected with the cover body to form a whole, so the insulating cover is compact in structure, small in volume and simple to operate.

Description

Insulating cover
Technical field
The present invention relates to electrical equipment technical field, especially a kind of insulating cover.
Background technology
Existing switchgear adopts SF6 gas that high-pressure vacuum switch is sealed insulation more; Because SF6 gas is carrying out having toxicity behind the arc extinguishing, and be prone to reveal, cause the equipment operation fault, casing is long-pending big; High to sealing requirements, processing technology is complicated, causes the casing cost high, safeguards that detection is complicated; Degree of protection is also not enough, and electrified body is exposed, receives the erosion of air, dust, is prone to cause the corrosion of electrified body; Reduced the grade of insulation, very easily cause human casualty accident, and volume has been bigger, it is big to take up room; Installation and Debugging are inconvenient, can not carry out repair and replacement in the scene, and the assembling maintenance is inconvenient.
Summary of the invention
Be prone to reveal in order to overcome existing switch cubicle gas insulated apparatus, have potential safety hazard, volume is big, and the deficiency of maintenance trouble the invention provides a kind of insulating cover.
The technical solution adopted for the present invention to solve the technical problems is: a kind of insulating cover; Comprise cover body, incoming line, three station plug-in strips action chamber, insulated tension pole, vacuum extinction chamber and line outlet; Incoming line is positioned at the cover body top; Three station plug-in strips action chamber is positioned at the cover body middle part, and insulated tension pole, vacuum extinction chamber and line outlet are positioned at the cover body bottom.
According to another embodiment of the invention, comprise that further incoming line has three, is arranged side by side on the cover body.
According to another embodiment of the invention, comprise that further the vacuum extinction chamber is connected on the insulated tension pole, line outlet is connected bottom, vacuum extinction chamber.
The invention has the beneficial effects as follows, adopt the form of solid dielectric insulation, removed potential safety hazard, and vacuum extinction chamber and cover body are linked as an integral body, compact conformation, advantages of small volume, simple to operate.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is a structural representation of the present invention.
1. cover bodies among the figure, 2. incoming line, 3. three station plug-in strips action chamber, 4. insulated tension pole, 5. vacuum extinction chamber, 6. line outlet.
Embodiment
Like Fig. 1 is structural representation of the present invention; A kind of insulating cover; Comprise cover body 1, incoming line 2, three station plug-in strips action chamber 3, insulated tension pole 4, vacuum extinction chamber 5 and line outlet 6; Incoming line 2 is positioned at cover body 1 top, and three station plug-in strips action chamber 3 is positioned at cover body 1 middle part, and insulated tension pole 4, vacuum extinction chamber 5 and line outlet 6 are positioned at cover body 1 bottom.Incoming line 2 has three, is arranged side by side on the cover body 1.Vacuum extinction chamber 5 is connected on the insulated tension pole 4, and line outlet 6 is connected 5 bottoms, vacuum extinction chamber.
Adopt the form of solid dielectric insulation, removed SF6 gas potential safety hazard, avoided the gas leakage problem; Substituted gas tank and associated components with insulating cover, switch block is installed in the cover body 1, the incoming line 2 through cover body 1 top and the line outlet 6 of bottom connect with loop up and down; And vacuum extinction chamber 5 and cover body 1 be linked as an integral body; Compact conformation, advantages of small volume, simple to operate.
