Technical Field

[0001] The invention relates to the technical field of mutual inductor manufacturing, and in particular to a centralized oil immersion system for a mutual inductor body. Background Art

[0002] After the oil-immersed current transformer is dried, it is assembled in the transformer housing for vacuum oil immersion. Currently, traditional vacuum oiling requires a single vacuum oiling operation, which has problems: vacuum oiling must be performed after each product is assembled and leak-checked, which results in a long exposure time and the body of the device is at risk of moisture. Multiple units are required to vacuum oil each product, which consumes a lot of energy. There is a high reliance on parts such as the housing, and untimely supply of parts will affect production progress. There are more or less dust and impurities on the surface of the body, and these impurities left in the product will affect the later operation of the product.

[0003] Therefore, in response to the above problems, a centralized oil immersion system for transformer bodies is proposed, which can perform vacuum oil immersion treatment on batches of transformer bodies, enhance the oil injection effect and reduce dispersion; during oil immersion, the system can flush the outer surface of the body through hot oil circulation. The system has its own oil storage tank to reduce dependence on external components, thereby reducing the exposure time of the body and reducing energy consumption. Summary of the invention

When in use, the vacuum unit 3 is started to evacuate the oil immersion tank 1 through the vacuum pipeline 201, and the transformer oil in the oil storage tank 2 is injected into the oil immersion tank 1 through the oil pipeline 202, and the transformer oil in the oil immersion tank 1 is introduced into the oil purification unit 4 through the purification pipeline 203 and the transformer oil is introduced into the oil storage tank 2 through the first circulation conduit to realize circulation purification.

[0023] The control component includes a first electric valve 301 and a second electric valve 302; the first electric valve 301 is arranged on the outer side of the oil pipeline 202, and the second electric valve 302 is arranged on the outer side of the purification pipeline 203. When in use, the opening and closing of the oil pipeline 202 are controlled by the first electric valve 301, and the opening and closing of the purification pipeline 203 are controlled by the second electric valve 302. The closing component includes a cover plate 401 and an input pipe 402; a cover plate 401 is arranged above the oil immersion tank 1, and an input pipe 402 is arranged above the cover plate 401. The closing component also includes an output pipe 403; an output pipe 403 is arranged above the cover plate 401, and the air pressure in the oil immersion tank 1 is maintained in a negative pressure state through the output pipe 403; the upper part of the oil immersion tank 1 is sealed by the cover plate 401, and the transformer oil input from the oil pipeline 202 is introduced into the oil immersion tank 1 through the input pipe 402.

[0024] When working, firstly, the transformer body 5 to be processed is quickly and securely placed in the oil immersion tank 1, and then the vacuum unit 3 is started, which is connected to the oil immersion tank 1 through the vacuum pipe 201, and the oil immersion tank 1 is vacuumized. The purpose of this step is to remove the air and moisture in the tank and on the surface of the transformer body, so as to create the best vacuum environment for the subsequent oil immersion treatment. The vacuuming process needs to be continued until the predetermined process time is reached to ensure that the air inside and on the surface of the transformer body is fully removed.

[0025] When the oil immersion tank 1 reaches the required vacuum degree, the oil filling operation is then performed; the oil delivery pipeline 202 is opened by the first electric valve 301 in the control component, so that the transformer oil in the oil storage tank 2 is slowly injected into the oil immersion tank 1 under the action of gravity or a pump; when the oil immersion tank 1 is filled and reaches the predetermined oil immersion time, the oil purification unit 4 is started; the unit is connected to the oil immersion tank 1 through the purification pipeline 203, and the transformer oil in the tank is sucked in and circulated and purified; the purified transformer oil is re-injected into the oil storage tank 2 through the first circulation pipeline 204, forming a closed-loop circulation; this process not only removes impurities and moisture in the oil, but also effectively rinses the outer surface of the device body through the hot oil circulation, removing dust and impurities attached to the device body;

After the oil is filled and the process time is reached, the oil purification unit 4 is started to circulate and purify the transformer oil in the oil immersion tank 1, so as to achieve the purpose of flushing the transformer body 5; the oil immersion tank 1 can be used to place multiple groups of transformer bodies 5, so that a batch of bodies can be vacuum immersed in oil, which can enhance the oil filling effect and reduce the dispersion. During the oil immersion, the outer surface of the body is flushed by hot oil circulation. The use of the self-contained oil storage tank 2 can reduce the dependence on external components, reduce the exposure time of the body, and reduce energy consumption.
