Problems solved by technology

[0004] Insulated busbars are generally divided into two types according to the insulation method, one is gas-insulated busbar, and the other is composite solid insulated busbar. Since gas-insulated busbars must be inflated on site, it is necessary to vacuum, inflate, moisture control and other gas treatment processes on site. , and the gas-insulated busbar is easily affected by the installation environment, which may cause dust, conductive particles, moisture, etc. to enter the gas box, thereby affecting the insulation performance of the busbar itself

Embodiment 1

[0016] A new type of composite silicone rubber solid insulated bus bar, which includes a conductive tube 1, a coupling agent layer 2, a main insulating layer 3, a metal shielding layer 4, a grounding layer 5, and a heat shrinkable sleeve protective layer 6 from the inside to the outside. The end of the layer 3 and the protective layer 6 of the heat-shrinkable sleeve adopt an interference fit to form a stepped taper structure, the material of the conductive tube 1 is T2Y red copper, the material of the main insulating layer 3 is composite silicone rubber, and the material of the metal shielding layer 4 and the grounding layer 5 Both are T2R red copper foils. The breakdown strength of the composite silicone rubber is 20-24kV / mm under standard conditions. The interface contact between the insulating layer 3 and the protective layer 6 of the heat-shrinkable sleeve should be as smooth as possible.

Abstract

The invention relates to a novel composite silicone rubber solid insulation bus. The insulation bus sequentially comprises a conductive tube, a coupling agent layer, a main insulation layer, a metal shielding layer, a grounding layer and a heat shrinkable sleeve protective layer from inside to outside. An interference fit is adopted between an end portion of the main insulation layer and the heat shrinkable sleeve protective layer, to form a stepped taper structure. A high-voltage charging part inside the composite silicone rubber solid insulation bus is completely sealed inside the silicone rubber. A semiconductive layer is disposed on inner and outer surfaces of the composite silicone rubber. An inner surface layer is in contact with high potential. The composite silicone rubber solid insulation bus belongs to a high voltage insulation manner and has a strong anti-electric shock capability and high mechanical strength. Therefore, the bus is not vulnerable to environmental interference and has high reliability.
