Abstract

The invention relates to a leakage plugging structure and a leakage plugging method. According to the leakage plugging method, the end of a gap between a transmission shaft and an equipment flange is plugged through a first sealing ring, and then a sealing sleeve is sleeved and sealant is filled, so that the sealant can be ensured not to flow into the gap between the transmission shaft and the equipment flange. Moreover, the sealing between the sealing sleeve and the transmission shaft is realized after the sealant is cured. Then a second sealing ring is sleeved on the outer side of the sealing sleeve, and a fixing seat is continuously sleeved, so that the sealing connection between the fixing seat and the sealing sleeve is realized. When the fixing seat is fixed relative to the equipment flange, the leakage plugging of a shaft seal on the transmission shaft is realized. That is to say, the operation mode only needs to sequentially sleeve parts for sealing on the transmission shaft, and the sealant and the two sealing rings are arranged, so that the shutdown work is not needed, a large amount of gas does not need to be filled, the operation can be directly carried out on the transmission shaft, and the operation is simple.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a leakage sealing structure and a leakage sealing method. Background technique [0002] The shaft seal of the transmission shaft in the GIS (GAS insulated SWITCHGEAR, gas-insulated metal-enclosed switchgear) knife switch equipment is due to aging and wear of the seal, causing gas leakage, which affects the normal operation of the equipment. The existing technical measures include: 1. Temporary treatment, replenish the air pressure to the rated value, and then replenish the air to the rated value when the leakage is no longer alarmed; 2. The radical treatment method is to cut off the power of the equipment, disassemble it for overhaul, and replace the sealing body. Repair equipment. [0003] Yet above-mentioned two kinds of modes have the following defects: 1, temporary treatment will not only waste a large amount of SF6 (sulfur hexafluoride) gas, cause gas pollution...
