Problems solved by technology

[0002] When the transformer is undergoing the overhaul of the suspension cover, the transformation of the radiator, and the removal of the radiator, it is necessary to collect and recycle the transformer oil in the radiator of the transformer. A 110kV natural wind cooled transformer generally has more than 20 radiators. The working method is to drain the oil from the transformer radiators one by one to recycle. On the one hand, the efficiency is low, and it takes at least 4 hours for 20 radiators; secondly, it is inconvenient to move the oil pipes, oil basins, and oil pumps on site, and the construction site is relatively chaotic; in addition, special personnel are required Supporting the oil pipe, starting and stopping the motor, etc., waste a lot of manpower, and easily cause transformer oil to spill

Embodiment 1

[0020] Such as figure 1 A transformer radiator oil automatic collection device is shown, which includes a multi-channel oil collection funnel 2, an oil collection tank and an oil storage. The oil collection tank 5 is connected, and the oil collection tank transfers the oil to the oil storage through the automatic transfer device.

Embodiment 2

[0022] This embodiment is refined on the basis of the principles of the foregoing embodiments.

[0023] Now take the 3-way oil collecting funnel as an example to illustrate the specific implementation of this scheme.

[0024] The 3-way oil collecting funnel is hung under the oil discharge hole of the transformer radiator through the 3-way oil collecting funnel. The oil pipe recovers the oil to the oil reservoir, and the oil inlet pipe 3 and the oil inlet pipe 1 can automatically retract and release the oil pipe through the connecting pipe collection device 4; a high oil level detection device, a medium oil level detection device and a low oil level detection device are installed in the oil collection tank The detection device realizes the collection of the oil level. The high, middle and low among the high oil level detection device, the middle oil level detection device and the low oil level detection device are relative positions; through the control system, the oil level of...

Abstract

The invention discloses an automatic oil collecting device of coolers of transformers. The automatic oil collecting device of the coolers of the transformers comprises multiple oil collecting funnels, an oil collecting tank and an oil storage device. Each oil collecting funnel is fixed to the position below an oil discharging hole of the corresponding cooler of the transformer through a movable connecting piece and communicates with the oil collecting tank through a connecting pipe. The oil collecting tank transfers oil to the oil storage device through an automatic transferring device. Oil discharging operation is conducted on the multiple coolers at the same time through the multiple oil collecting funnels, so that the oil discharging efficiency is greatly improved. The oil collecting funnels are arranged on the coolers through the movable connecting pieces and are convenient to detach and repeatedly use. Long-distance operation of the oil collecting funnels is achieved through the connecting pipe, and therefore the problem that installation of the oil collecting tank is inconvenient is solved. Oil is transferred through the automatic transferring device, so that labor intensity is lowered, and the transformer oil is prevented from being sprinkled.

Description

technical field [0001] The invention relates to the field of transformers, in particular to an automatic radiator oil collection device for transformers. Background technique [0002] When the transformer is undergoing work such as overhaul of the suspension cover, renovation of the radiator, and removal of the radiator, it is necessary to collect and recycle the transformer oil in the radiator of the transformer. A 110kV natural air-cooled transformer generally has more than 20 radiators. The working method is to drain the oil from the transformer radiators one by one to recycle. On the one hand, the efficiency is low, and it takes at least 4 hours for 20 radiators; secondly, it is inconvenient to move the oil pipes, oil basins, and oil pumps on site, and the construction site is relatively chaotic; in addition, special personnel are required Supporting oil pipes, starting and stopping motors, etc., waste a lot of manpower, and easily cause transformer oil to spill.
