To achieve the goals above, the utility model uses following technical scheme:
A kind of gas-filling cabinet band sealing bus bar connecting sleeve, including conducting rod and the insulation being wrapped on the outside of the conducting rod
Body, wherein the outer surface of insulator is circumferentially arranged with flange, and the flange is equipped with installation inserts, in the insulator with it is described
The opposite position of flange is equipped with gauze screen, and the gauze screen is connect with the installation inserts.
The insulator is an integral structure using poured with epoxy resin and outer surface is coated with aluminium layer, the aluminium layer with
The installation inserts links together, and ground potential is formed after installation.
The outer surface of the conducting rod is equipped with sandblasting layer.
The side of the flange is equipped with sealing surface.
The flange is ring structure.
The advantages of the utility model and beneficial effect are:
1. high mechanical strength, easy for installation: the casing of the utility model can bear higher lateral mechanical bend and destroy
Load, to guarantee that product has higher mechanical strength and ability of anti-deformation；Each dimensional machining accuracy of product is high, and product has logical
With property, maintenance is convenient and simple.
2. insulation performance is high, partial discharge is low: the utility model has gauze screen, casing electric fields uniform, external belt due to inside
There is aluminium shielding layer, so this product insulation performance is high, discharge capacity is low, securely and reliably.
3. good seal performance: the conducting rod of the utility model and resin-bonded are close, and flange mounting surface is smooth, sealing performance
By force.

Specific embodiment
In order to keep the purpose of this utility model, technical solution and advantage clearer, with reference to the accompanying drawing and it is embodied
The utility model is described in detail in example.
As shown in Figure 1, a kind of gas-filling cabinet provided by the utility model band sealing bus bar connecting sleeve, including conducting rod 2
And it is wrapped in the insulator 1 in 2 outside of conducting rod, wherein the outer surface of insulator 1 is equipped with peace circumferentially arranged with flange 8, flange 8
Assembly part 3, the interior position opposite with flange 8 of insulator 1 are equipped with gauze screen 4, and gauze screen 4 is connect with installation inserts 3.
As shown in figure 3, insulator 1 is an integral structure using poured with epoxy resin and outer surface is coated with aluminium layer 6, aluminium
Layer 6 links together with installation inserts 3, and ground potential is formed after installation.
As shown in Fig. 2, having carried out blasting treatment on the surface of conducting rod 2, sandblasting layer 5, the table of conducting rod 2 after sandblasting are formed
Face is very coarse.The part of sandblasting is wrapped up by resin, and conducting rod 2 is sticked together with the resin after solidifying, and makes resin and conduction
Will not be there are gap between bar 2, a possibility that eliminating gas leakage.
Flange 8 is ring structure, and side is equipped with sealing surface 7.
Installation inserts 3 welds together with gauze screen 4, is installed along in pressure gel mold with conducting rod 1, is being suitable for
Temperature and pressure under to mold inject liquid-state epoxy resin, it is to be solidified completely after obtain casing finished product.Using pressure gel at
Type technological forming, casing can have very high dielectric strength；Solidification temperature and time are controlled in resin curing process, resin can be made
Better mechanical strength is obtained, higher lateral mechanical bend failing load can be born.
As shown in figure 3, the outer surface part position of insulator 1 has carried out aluminium-plated, in resin surface aluminium is formd after aluminium-plated
Layer 6, aluminium layer 6 links together with installation inserts 3, and after casing is mounted on cabinet body, aluminium layer 6 and cabinet body contact be will form completely
Ground potential shielded layer enhances the safety of Inflatable cabinet body.In mounting flange side, finishing has sealing surface 7, forms high-precision
Plane enhances the leakproofness to gas-filling cabinet.
A kind of gas-filling cabinet provided by the utility model band sealing bus bar connecting sleeve, it is integrally melted by epoxy resin
Type is the air-tightness connection equipment on gas-filling cabinet, can connect inside and outside cabinet in the case where not destroying gas-filling cabinet air-tightness
