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 tightness. 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; a circular table is arranged on the first sealing surface; the second sealing surface is provided with a mounting groove matched with the circular table; the first sealing surface is provided with an annular groove; the second sealing surface is provided with an annular flange matched with the annular groove; a clamping groove is formed in the side wall in an opening of the mounting groove; a first sealing ring is arranged in the clamping groove; a connecting ring is butted between the annular flange and the first sealing ring; an annular projection for extruding the annular flange to enable the connecting ring to extrude the first sealing ring is arranged on one side, far from the boss, in the annular groove; a self-return elastic block is arranged in the left joint; and the right joint is provided with an opening block butted against the self-return elastic block.
Description
Technical field [0001] The invention relates to a sealed joint controller. Background technique [0002] Gas-insulated substation (GIS) uses sulfur hexafluoride (SF6) gas with excellent insulation and arc extinguishing performance as insulation and arc extinguishing medium, and seals all high-voltage electrical components in a grounded metal cylinder, which is similar to traditional open-type substations. Compared with the advantages of long maintenance period, small maintenance workload, rapid installation, low operating cost, and no electromagnetic interference. Most of the current substations are gas-insulated substations. However, with the large number of gas-insulated substations being put into operation, due to the inadequate production and installation technology of the sealed joint controller, the air leakage of the equipment gas chamber is becoming more and more serious. Therefore, the daily maintenance It is necessary to supplement the air chamber of the equipment with...
