Description

Technical Field

[0001] The utility model relates to the technical field of vacuum oil injection, in particular to a vacuum impregnation oil level controller. Background Art

[0002] In transformer vacuum oil filling or capacitor vacuum impregnation equipment, the design of the oil level controller has a great impact on product quality and oil filling oil level height. Existing oil filling or impregnation equipment on the market usually adopts gravity oil filling, which is simple and reliable. It can achieve the effect of continuous oil filling or impregnation by relying on gravity and avoid the situation of untimely oil replenishment. However, in actual use, the tank body is usually fixed at the required position. When the oil level in the tank body is getting lower and lower, the amount and speed of the oil in the tank flowing down will become lower and lower, making the front and rear oil output inconsistent, which is inconvenient to use. Utility Model Content

[0003] In view of the deficiencies of the prior art, the utility model provides a vacuum impregnation oil level controller, which solves the problem that when the oil level in the existing tank becomes lower and lower, the amount and speed of the oil flowing downward will become lower and lower, resulting in inconsistent oil output from front and back.

[0004] To achieve the above objectives, the utility model is implemented through the following technical scheme. The utility model provides a vacuum impregnation oil level controller, including a degassing tank body and a column, a guide crawler is installed on the column, a control end and a fixed end are provided on the guide crawler, a screw rod is vertically screwed in the control end, the degassing tank body is installed on the fixed end, a lifting mechanism is provided on the column, and a vacuum tube, an oil inlet pipe, an oil outlet pipe, an oil drain pipe and an overflow pipe as well as a magnetic flap level gauge are installed on the degassing tank body.

[0005] Preferably, the lifting mechanism comprises a reducer and a fixed seat mounted on the column, the upper end of the screw rod is connected to the driving end of the reducer, and the lower end of the screw rod is rotatably mounted on the fixed seat.

[0006] Preferably, the oil inlet pipe, the oil outlet pipe and the oil drain pipe are all equipped with bellows.

[0007] Preferably, a manual ball valve is connected between the magnetic flap level gauge and the degassing tank body.

[0008] Beneficial Effects

[0009] The utility model provides a vacuum impregnation oil level controller, which has the following beneficial effects:

[0010] 1. This oil tank adopts a degassing tank body. The oil injected into the degassing tank body can be vacuum degassed here again. At the same time, the degassing tank body is installed on the side end of the guide crawler. The reducer drives the screw to rotate and then drives the guide crawler to move on the column. The height of the degassing tank body is adjusted by the height of the oil in the tank body transmitted by the magnetic flap level gauge, thereby ensuring the stability of oil filling or immersion, and no oil leakage will occur.
