Description

technical field [0001] The invention relates to a transformer dielectric loss test wiring device. Background technique [0002] Transformer insulation is composed of many insulating materials. Any insulating material will always lose energy under the action of voltage. If the dielectric loss is too large, the temperature of the dielectric will rise and the material will age (brittle, decompose, etc.). Therefore, the size of the dielectric loss is an important indicator to measure the electrical properties of the insulating medium. [0003] At present, the on-site 110kV, 220kV, and 500kV voltage level transformer dielectric loss measurement test is a routine power failure test, which needs to be measured after the transformer bushing lead is removed during power failure. When measuring, it is necessary to short-circuit the three-phase bushing terminals on the high-voltage side and then perform pressurization operation. At present, when the dielectric loss measurement is p...

AI Technical Summary

Problems solved by technology

At present, when the dielectric loss measurement is performed without removing the lead wires, there is a lack of suitable clamps to fix the test lead wires. At the same time, due to the high voltage side bushing of the transformer, the short circuit requires the operator to use an aerial work vehicle for wiring work.

[0004] During the pre-test period, the high-altitude operation vehicle was used frequently, which caused problems in vehicle deployment, hindered on-site operations, and caused people to wait for vehicles

At the same time, using the aerial work vehicle to cooperate with the wiring requires on-site attention to the control measures for the safe distance from the live body, and there is a hidden danger of safety accidents caused by accidentally touching the live body

Moreover, it takes a long time to use the aerial work vehicle for wiring, resulting in low work efficiency
