[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a residual oil collection device for oil-immersed transformer maintenance, including an oil tank, an oil inlet pipe is provided on the top of the oil tank, the oil inlet pipe is connected to the input end of the oil pump, the output end of the oil pump is connected to the oil tank, and an oil outlet pipe is provided at the bottom of the oil tank, the oil outlet pipe is connected to the input end of the oil drain pump; the oil inlet pipe is connected to the oil inlet device.

[0005] Preferably, the oil inlet device is a funnel or a connecting pipe, and the oil inlet device is flange-connected to the oil inlet pipe.

[0006] Preferably, the end of the connecting pipe is provided with a flange joint or a threaded joint.

[0007] Preferably, manual lifting devices for driving the oil tank to rise and fall are provided on both sides of the oil tank.

[0008] Preferably, the manual lifting device and the oil drain pump are arranged on the trolley.

[0009] Preferably, a liquid level window is provided on the side wall of the oil tank.

[0010] The utility model provides an oil-immersed transformer maintenance residual oil collection device, which saves the tedious pipeline layout work during the residual oil discharge of the transformer, facilitates the cooperation of operators, reduces working hours, and reduces the labor cost of residual oil discharge operations. At the same time, it reduces the probability of oil splashing and oil leakage, is conducive to the maintenance of the maintenance site environment, and improves the level of safe and civilized construction.
