The tangibly Switch main body of described full-shield is made by the macromolecule modified renewable reusable environment-friendly materials that based on ethylene-propylene diene copolymer are main body.
A protruding insulated tension pole in the tangibly Switch main body of described full-shield, connect a mechanism driving coupling arrangement by insulated tension pole, described mechanism driving jockey when work drive insulated tension pole between two outlet conductive contacts to full-shield the vacuum switch tube in the tangibly Switch main body make opening and closing movement.
The tangibly Switch main body of described full-shield, insulated tension pole and mechanism driving coupling arrangement all are arranged in the casing.
The contact position of and full-shield tangibly Switch main body protruding at described insulated tension pole is provided with a C type seal-moving spare, is used for the overall tightness between the tangibly Switch main body of reinforced insulation pull bar and full-shield.
Further technical scheme of the present invention is, the tangibly Switch main body of described full-shield can adopt the cross tangible Switch main body of full-shield that goes out wire terminal, at the other end joint of described two outlet conductive contact correspondences external power supply voltage transformer or zero sequential potential transformer, voltage transformer and zero sequential potential transformer are attached to the tangible vacuum circuit-breaker of this full-shield bottom by another casing.
Also be provided with ring current transformer and zero sequence current mutual inductor at described insulating sleeve with the Switch main body junction, current transformer is positioned at the inside of casing.
The invention has the beneficial effects as follows and to join between the conductive contact of insulating body and the cable, interface seals and insulation processing, removed insulating sleeve from, not only Zheng Ti fail safe does not reduce, and structurally simplify more, cost also reduces greatly, is particularly useful for the underground construction of burying underground.
