Abstract

The invention relates to gas-insulated totally-enclosed electrical equipment. The equipment specifically comprises a closed shell, a basin-type insulator, a conductive seat and a conductor, wherein the basin-type insulator is fixedly arranged in the closed shell; one end of the conductive seat is fixedly connected with the basin bottom of the basin-type insulator, and the other end of the conductive seat is perpendicular to the basin-type insulator and overhangs outwards; the conductor is used for flowing; the conductor is inserted into an overhanging end of the conductive seat, and the insertion connection position is located at the basin opening or outside the basin opening. The equipment is advantaged in that the plug-in mounting position of the conductor and the conductive seat of the gas-insulated totally-enclosed electrical equipment is positioned at the basin opening of the basin-type insulator or outside the basin opening, and is far away from the basin bottom of the basin-type insulator, namely, the connection position of the conductive seat and the basin-type insulator is separated from the connection position of the conductive seat and the conductor; the electric field in a narrow space at the joint of the conductive seat and the basin-type insulator can be conveniently controlled; in addition, the heating position is transferred to the outer side of the concave cavity of the basin-type insulator, so the space is relatively wide, the air flow is smooth, the heat dissipation effect is optimized, and temperature rising is favorably controlled.

Description

technical field [0001] The invention relates to a gas-insulated fully-enclosed electric device. Background technique [0002] In gas-insulated fully enclosed electrical equipment such as GIS or GIL, the conductive connection structure usually includes a conductive seat and a conductor, and the conductive seat is fixedly installed on an insulating support to play the role of support and flow. There is a mating end, which is used to be inserted into the other, and conductive contacts are provided on the mating end to realize the conductive connection between the two. Since GIS or GIL are used in high-voltage occasions, the requirements for the current flow capacity and insulation performance of the equipment are relatively high, and the shape of the outer surface of the conductive seat often has a great influence on the electric field distribution of itself and the insulating support surface. Therefore, how to design and optimize the conductive The structure of the seat itsel...
