Abstract

The invention relates to a bus connecting sleeve, in particular to a sealed bus connecting sleeve for a gas insulated switchgear. The sealed bus connecting sleeve comprises a conducting rod and an insulator wrapping the outer side of the conducting rod; a flange is arranged on the outer surface of the insulator in the circumferential direction, an installation insert is arranged on the flange, a shielding net is arranged at the position, opposite to the flange, in the insulator, and the shielding net is connected with the installation insert. The insulator is of an integrated structure formedby pouring epoxy resin, an aluminum layer is sprayed on the outer surface of the insulator, the aluminum layer and the installation insert are connected together, and a ground potential is formed after installation. The sealed bus connecting sleeve is high in mechanical strength, convenient to install, high in insulating property, low in partial discharge and good in sealing property.

Description

technical field [0001] The invention relates to a bus connection sleeve, in particular to a sealed bus connection sleeve for an inflatable cabinet. Background technique [0002] The connecting sleeve with sealed busbar is used for the insulation, sealing and supporting equipment used for the conductive part to pass through the inflatable cabinet. Once the connecting bushing is damaged, the busbar will be short-circuited to the ground, and the gas in the inflatable cabinet will leak. At present, the existing connecting sleeve has poor sealing performance, and long-term use will cause gas leakage due to cracking between the resin and the conductive rod, and the existing connecting sleeve has uneven electric field and large discharge. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a sealed bus connection sleeve for an inflatable cabinet to solve the shortcomings of the existing gas cabinet bus connection sl...
