Problems solved by technology
Most of the current substations are gas-insulated substations. However, with the large-scale operation of gas-insulated substations, the air leakage of the equipment gas chamber is becoming more and more serious due to reasons such as the production of sealing joint components and the inadequate installation process. Therefore, in daily maintenance It is necessary to replenish air to the air chamber of the equipment with serious air leakage, and sometimes it is necessary to repair the air chamber of the equipment with low pressure alarm, that is, a sealing joint assembly with good sealing performance is urgently needed on the market

The invention discloses a sealing connector assembly and aims at providing a sealing connector assembly good in sealing performance. According to the technical scheme, the sealing connector assembly is characterized by comprising a left connector provided with a first sealing face, and a right connector provided with a second sealing face; the first sealing face is provided with a boss, the second sealing face is provided with an installing groove matched with the boss, and the first sealing face is provided with an annular groove; the second sealing face is provided with an annular flange matched with the annular groove; a clamping groove is formed in the side wall of the position of an opening of the installing groove and internally provided with a first sealing ring, and the section of the first sealing ring is in a trapezoid shape; the side wall, located at the trapezoid lateral edge position, of the first sealing ring is opposite to the side wall of the boss, and an annular protrusion extruding the annular flange to make the clamping groove deform and extruding the first sealing ring towards the boss is arranged on the side, far away from the boss, in the annular groove.
Description
technical field [0001] The present invention relates to sealing joint assemblies. 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. However, with the large-scale operation of gas-insulated substations, the air leakage of the equipment gas chamber is becoming more and more serious due to reasons such as the production of sealing joint components and the inadequate installation process. Therefore, in daily maintenance It is necessary to supplement air to the air c...
