An Introduction

1. The leakage point of the substation equipment
As the main insulating medium for power equipment, SF6 gas plays an important role in equipment. Leakage of the substation equipment will reduce the insulation inside the equipment, seriously interfere with the normal operation of the equipment, and even cause accidents. And the air leakage defect tends to develop in a process, and the defect level increases with the severity of the air leakage, so it needs to be dealt with as soon as possible to eliminate hidden dangers.
For the GIS, switch device leakage phenomenon, the conventional non-blackout situation processing method: 1 to the gas leakage device to fill the air 2 to tighten the bolt. Although these two treatment methods are convenient, they are all palliative and fail to effectively treat the leaking parts.
——Insuring the equipment to avoid the insulation of the equipment, but the frequent air supply work increases the workload of the operation and maintenance personnel of the power station and the operation and maintenance cost of the substation, which cannot fundamentally solve the problem of equipment leakage.
——The method of fastening the bolt is simple and easy, but because the seal has been damaged or aged, it can only relieve the air leakage for a short time and cannot solve the fundamental problem. This method is still indispensable when the seal is completely ineffective.
For the leakage phenomenon of GIS and switchgear, the treatment method for power failure and pressure relief is as follows: (1) Disassemble the seal failure part and replace the seal. 2 Repair the gas leakage parts such as sand holes and cracks. Although these two schemes can effectively solve the problem of equipment leakage in the long-term, the impact and loss caused by the power outage to the power station is huge, and the processing method is time-consuming and laborious, which can be described as “high input and low output”.
——Replacing the seal can fundamentally solve the problem of equipment leakage. However, replacing the seal requires first stepping on the equipment, such as depressurizing, disassembling, replacing the seal, installing, and inflating. It is time-consuming and laborious, and the cost is high. The method of "doing half the work".
——The repair of the leaking part can solve the problem of equipment leakage for a long time, but the technical and process requirements of the maintenance personnel are high, and the requirements for the welding material are high, and the parts are subject to certain restrictions, and the welding operation cannot be performed. Sexuality.
2. Substation equipment leakage and oil pain points
There are many oil leakage problems in substation equipment. Oil stains adhere to the surface of the equipment and easily absorb dust, which seriously affects the appearance of the equipment. Long-term oil leakage will affect the normal operation of substation equipment and even cause accidents. Common treatment methods still have drawbacks, mainly as follows:
①Regular oil replenishment measures
②It takes time and effort to replace the seals after power failure
③With pressure welding, a lot of auxiliary work and preventive measures are required. The operation volume is large, the time is long, and the limitation is large. Most parts cannot be welded.
