Problems solved by technology
Most of the current substations are gas-insulated substations, but with the large-scale operation of gas-insulated substations, due to reasons such as the production of sealed joint controllers and inadequate installation processes, the air leakage in the equipment gas chamber is becoming more and more serious. Therefore, in daily maintenance Air must be supplied to the equipment air chamber with serious air leakage, and sometimes it is necessary to repair the equipment air chamber with low pressure alarm, that is, a sealing joint controller with good sealing performance is urgently needed on the market

The invention discloses a sealing joint controller, and aims to provide the sealing joint controller with excellent sealing performance. The sealing joint controller comprises a valve, a shunt block and a sealing joint; the sealing joint includes a left joint provided with a first sealing surface, and a right joint provided with a second sealing surface; the first sealing surface is provided with a circular table; and the second sealing surface is provided with a mounting groove matched with the circular table. The sealing joint controller is characterized in that a sealing piece with a N-shaped section is abutted against between the circular table and the mounting groove; a first sealing ring is abutted against between the bending place of the sealing piece and the end surface of the circular table; a second sealing ring is abutted against between the bending place of the sealing piece and the groove bottom of the mounting groove; one end part of the sealing piece is abutted against between the side wall of the circular table and the side wall of the mounting groove; a self-return elastic block is arranged in the left joint; and the right joint is provided with an opening block abutted against the self-return elastic block.
Description
technical field [0001] The present invention relates to sealed joint controllers. Background technique [0002] Gas-insulated substation (GIS) uses sulfur hexafluoride (SF6) gas with excellent insulation and arc-extinguishing properties as the insulation and arc-extinguishing medium, and seals all high-voltage electrical components in a grounded metal cylinder, which is different from traditional open substations. Compared with it, it has the advantages of long maintenance period, small maintenance workload, quick installation, low operating cost, and no electromagnetic interference. Most of the current substations are gas-insulated substations, but with the large-scale operation of gas-insulated substations, due to reasons such as the production of sealed joint controllers and inadequate installation processes, the air leakage in the equipment gas chamber is becoming more and more serious. Therefore, in daily maintenance It is necessary to supplement the air chamber of the...
