Embodiment Construction

[0018] like Figure 1 to Figure 3 As shown, a solid insulating fully sealed switch insulating cover of the present invention, the solid insulating fully sealed switch insulating cover is made of integral casting of epoxy resin. The solid insulation fully sealed switch insulation cover 10 is a long tube with a rectangular cross section. There is a large boss 1 on one side of the long tube. There is a double-pass bushing hole 10 inside the big boss 1. The double-pass bushing hole 10 communicates with the inside of the solid insulation full-sealed switch insulation cover, and is used to install the double-pass bushing. There is an observation hole 11 on the long tube above the large boss 1, and there is also an observation hole 11 at the opposite symmetrical position, which is convenient for the user to observe the solid state. The movement state of the parts in the insulation cover of the fully insulated switch. Have a grounding contact head hole 8 on the bottom surface of the ...

Abstract

The invention relates to a solid insulating omniseal switch insulating cover which is a long barrel with a rectangular cross section; a big lug boss is arranged at one side of the long barrel, and a bipass bushing hole is arranged in the big lug boss and is communicated with the interior of the solid insulating omniseal switch insulating cover; a grounding contact head hole is arranged on the bottom surface of the solid insulating omniseal switch insulating cover which approaches to the bipass bushing hole, and a vacuum bubble cover is arranged on the bottom surface of the other side of the solid insulating omniseal switch insulating cover which approaches to the long barrel; the height of the vacuum bubble cover is less than the height of the lower end of a connecting terminal hole; a recess which is communicated with the width direction of the long barrel is arranged at the other side on the upper end of the vacuum bubble cover, which is far way from the long barrel, and a joint pin sleeve is arranged on the bottom surface of the long barrel which is arranged at the lower end of the vacuum bubble cover; a joint pin hole is arranged in the joint pin sleeve, leads to the vacuum bubble cover and is concentric with the central line of the vacuum bubble cover; an outward and downward flange is arranged at the circumference of an opening part of the upper end of the long barrel, and a seal groove is arranged on the flange. The invention strengthens the insulating level and reduces the volume of an isolating switch.

Description

technical field [0001] The invention relates to a solid-insulated fully-sealed switch insulation cover, in particular to a solid-insulated fully-sealed switch insulation cover used for segmentally isolating grid current in a power transmission and distribution cabinet as an obvious disconnect switch. Background technique [0002] In the prior art, it is used for gas-insulated ring network cabinets, and the gas is used to seal and insulate the high-voltage vacuum switch; because the gas SF6 used is toxic after arc extinguishing, has a greenhouse effect, and is easy to leak, the metal box Large volume, high requirements for sealing, complex processing technology, resulting in high cost of the box, complicated maintenance and testing, insufficient protection level, and the exposed charged body is eroded by air and dust, which is easy to cause corrosion of the charged body and reduces the The level of insulation is very likely to cause personal injury or death.
