Tool special for disposal of leaking oil of vent valve of main transformer radiator

Abstract

The invention discloses a tool special for disposal of leaking oil of a vent valve of a main transformer radiator. The tool comprises a sleeve operation rod, a protection cover, a fixing piece and a seal ring operation rod. The side wall of the protection cover is provided with transparent organic glass. The upper end of the protection cover is connected with the sleeve operation rod. The lower end of the sleeve operation rod is provided with a sleeve. The sleeve is arranged in the protection cover. The sleeve operation rod is in sealed connection with the protection cover. The seal ring operation rod is in sealed connection with the side wall of the protection cover. The lower end of the protection cover is in sealed connection with a protection cover bottom plate. The protection cover bottom plate is provided with the fixing piece for fixation and provided with a matched hole communicating with the protection cover. By means of the tool, a seal ring of the vent valve is safely and efficiently replaced, it can be ensured through all-directional sealing that the loss of oil of a transformer in the replacing process is reduced to a very low level, the working environment cannot be contaminated, the falling of parts in the replacing process is avoided, safety is increased, and the work efficiency can be improved with the aid of the tool.

Description

technical field [0001] The invention relates to the technical field of electric tools, in particular to a special tool for oil leakage treatment of exhaust valves of main transformer radiators. Background technique [0002] The transformer is the main equipment of the substation. Due to the thermal expansion and contraction of the sealing ring and the aging of the rubber ring, there will be defects of oil leakage from the exhaust valve of the radiator of the main transformer, and the high casing base or the closing of the oil storage tank valve If it is not tight, it will cause a large amount of transformer oil to leak when the defect is eliminated. In severe cases, it is necessary to refill and filter the oil, which increases the power outage time and production costs. [0003] The traditional defect elimination mode is prone to fall from high altitude due to transformer oil polluting the workplace, resulting in high operational risk and low work efficiency.

[0002] The transformer is the main equipment of the substation. Due to the thermal expansion and contraction of the sealing ring and the aging of the rubber ring, there will be defects of oil leakage from the exhaust valve of the radiator of the main transformer, and the high casing base or the closing of the oil storage tank valve If it is not tight, it will cause a large amount of transformer oil leakage when the defect is eliminated. If it is serious, it needs to refill and filter oil, which increases the power outage time and production cost.

[0003] Due to the pollution of transformer oil in the traditional mode of defect elimination, it is easy to cause the situation of falling from high altitude, high operation risk and low work efficiency
