Abstract

The invention relates to a basin type insulator for high-current electric power transmission equipment. The basin type insulator at least comprises a tube type flange, a connecting conductor and an insulation casting body, and is characterized in that the insulation casting body is in an annular shape, the connecting conductor is arranged in a hole of the annular insulation casting body and is in bilateral symmetry by using the annular insulation casting body as the center, the tube type flange is arranged outside the annular insulation casting body, the upper and lower surfaces, near the excircle part, of the annular insulation casting body are respectively and correspondingly provided with first annular grooves, a first O-shaped sealing ring is arranged in each first groove, the upper and lower surfaces, near the inner circle part, of the tube type flange are respectively and correspondingly provided with second annular grooves, a second O-shaped sealing ring is arranged in each second groove, two ends of the connecting conductor are respectively provided with a plurality of annular conducting grooves, and a spring contact is sheathed on each annular conducting groove. The basin type insulator has the advantages that the problem of usage occasion limitation of the traditional basin type insulator is solved, and in addition, the sealing performance is good.

Description

technical field [0001] The invention particularly relates to a basin-type insulator used for large-current power transmission equipment, which belongs to the field of electric power. Background technique [0002] In ordinary pot insulators, the connection between the pot insulator and the internal conductor of the GIB is a plug-in type, that is, the connection part of the pot insulator is designed as a plug, and the connection part of the conductor is designed as a socket. The combination of the two forms a current channel to transmit power. . This form of connection has a complex structure, a large joint, and requires a relatively large inner diameter of the busbar cylinder, which limits its application to a certain extent. GIB is the abbreviation of "Gas insulated transmission bus", and the Chinese name is "gas insulated transmission bus". Contents of the invention [0003] The invention proposes a new type of basin-type insulator to improve the problem of limited appl...
