Vacuum oil injection equipment is mainly used for vacuum oil injection of amorphous alloy transformers, high-voltage oil-immersed transformers, and capacitors. It can also be used for vacuum oil injections of other power products. Oil treatment equipment is used for vacuum filtration of transformer oil for oil-immersed transformers with 500KV voltage levels and below.
In a vacuum environment, the product to be injected with oil is first vacuum degassed. After reaching the vacuum degree required by the process, the treated insulating oil is injected into the body of the instrument, and the injected oil can be controlled through the flowmeter. Because in a vacuum environment, the insulating paint can fully penetrate into the gaps of the product coil, which improves the oil impregnation capacity and greatly improves the insulation strength of the coil
The amount of oil injected by each product can be controlled separately and can be pre-set. The oil injected speed can also be adjusted to meet the requirements of different processes. The oil storage tank is equipped with a heating system and placed on the oil filling tank, which not only saves space, but also facilitates the control of oil filling. The bottom of the oil filling tank can be equipped with an electric raceway or a trolley, which is conducive to the inlet of the product. The vacuum system is equipped with a vacuum filter, and the volatile oil and gas and water vapor are placed into the vacuum pump.
The oil filling tank can be designed in two types according to customer requirements, either with heating or without heating. For oil injection of transformers, the oil is usually directly drained and oiled, and the amount of oil injection is controlled through a liquid level gauge.
