Abstract

The invention discloses an oil changing device applied to an oiled-paper capacitive sleeve. The oil changing device comprises a to-be-replaced sleeve, a vacuum machine, a vacuum gauge, a fine filter,an oil pump, a coarse filter, a back pressure valve and an oil storage tank. The vacuum machine is connected with the sleeve to be replaced through a first pipeline, and a vacuum gauge and a first ball valve are sequentially arranged on the first pipeline. The output port of the oil storage tank is connected with the to-be-replaced sleeve through a second pipeline, and a third ball valve, the coarse filter, the oil pump, the fine filter and a second ball valve are sequentially arranged on the second pipeline. The input port of the oil storage tank is connected with the sleeve to be replaced through a third pipeline, and a fourth ball valve and the back pressure valve are sequentially arranged on the third pipeline. The problem that the whole sleeve cannot be replaced due to the fact that deteriorated transformer oil cannot be replaced during sleeve maintenance is solved.

Description

technical field [0001] The invention relates to the field of power system equipment maintenance, in particular to an oil changing device applied to an oil-paper capacitor bushing. Background technique [0002] Oil-paper capacitor bushing has the advantages of high insulation utilization coefficient, large specific capacitance, reasonable structure and small size, etc. Under the continuous action of internal voltage, the insulating medium of the bushing itself (capacitor cable paper, transformer oil) will gradually deteriorate. Exposure to the sun, wind and ultraviolet rays will gradually age the sealing rubber pads on the sealing surfaces, and the rubber pads will become hard and cracked, thus losing the sealing effect, causing oil leakage or allowing moisture and water to enter the casing. These deterioration phenomena will increase the dielectric loss of the bushing, cause local discharge, and even cause an explosion. [0003] At this stage, the casing cable paper is pro...
