Material is solved, is difficult to reclaim after shaping, is also easy to produce waste of material and also pollutes environment.
In the prior art, the Switch main body of environmental-protective gas-insulating uses composite insulating material, to meet in environment-friendly type gas
Insulation Problems under body environment, using a large amount of thermosets and a small amount of carbon steel sheet, cause production cost height, processing technology multiple
Miscellaneous cycle length, volume are big, structure type is complicated.
Above-mentioned prior art at least has the following disadvantages：
1st, SF6 gases are to be restricted the greenhouse gases of discharge, and can produce under high-temperature electric arc and many poisonous to human body to have
Harmful material, threat to life safety；
2nd, epoxy resin cost is high, is non-degradable material, is also easy to produce waste of material and environmental pollution；
3rd, the processing technology of the component such as the pole for the vacuum coater processed using epoxy material, insulating supporting positioning is answered
Miscellaneous cycle length, structure type are complicated, and volume is big, not easy heat radiation.
The content of the invention
It is an object of the invention to provide a kind of environment-friendly type Switch main body.
The purpose of the present invention is achieved through the following technical solutions：
The present invention environment-friendly type Switch main body, including prepackage type vacuum circuit breaker/vacuum load switch pole, main spindle box,
Three-station isolating grounding switch, isolation beam, Switch main body framework；
Prepackage type vacuum circuit breaker/vacuum load switch the pole, three-station isolating grounding switch, isolation beam are by heat
The working of plastics of plastic engineering injection molding, the main spindle box, Switch main body framework are assembled by carbon steel sheet.
As seen from the above technical solution provided by the invention, environment-friendly type Switch main body provided in an embodiment of the present invention,
Dielectric is used as using clean gas, it is to avoid pollution environment；Parts are recyclable in Switch main body, reduce discarded object, section
The about energy；Switch main body inner part modularized design, convenient disassembly improves production efficiency.
