A voltage test device for transformer insulating oil

Abstract

The invention discloses a transformer insulating oil withstand voltage test device, which includes a test body, two load poles are installed on the upper surface of the test body, and a pole for isolating the outside air is connected between the two load poles. In the water and dirty oil cup mechanism, the invention can use the plugging cover to seal the mouth of the oil storage cup, and at the same time clamp the electrode column with the help of the movable capsule block, so that the sundries attached to the side wall of the electrode column can be fully scraped off , so that the user does not need to spend time cleaning the inner wall of the oil cup, which improves the operator's testing efficiency, and can also pass hot air into the oil storage cup through the hot air circulation column to take away the moist gas in the cup. The inside of the entire oil storage cup is kept in a dry environment, thereby avoiding the situation that the insulating oil sample enters the cup and is affected by debris or water vapor, making the test data inaccurate.

Description

technical field [0001] The invention relates to the technical field of withstand voltage test, in particular to a voltage withstand test device for transformer insulating oil. Background technique [0002] Transformer oil is a kind of mineral oil obtained through distillation and refining from natural petroleum. It is a pure and stable liquid natural hydrocarbon with low viscosity, good insulation and good cooling performance obtained by refining the lubricating oil fraction in petroleum with acid and alkali. Compound mixture. Commonly known as square shed oil, a light yellow transparent liquid, it is used in oil-immersed transformers. In order to prevent the transformer from being damaged due to the aging of the insulating oil device oil during use, a withstand voltage test is often carried out. In the test, the insulating oil withstand voltage detector is often used. [0003] The most important part in the structure of insulating oil withstand voltage detectors that are ...

Problems solved by technology

[0004] For this reason, the present invention provides a transformer insulation oil withstand voltage test device to solve the problem that in the prior art, when sampling, dirt and debris or damp water vapor in the external environment are easily attached to the inner wall of the oil cup and the motor inside the oil cup. On the side wall, the insulating oil sample is affected by debris or water vapor when it enters, making the test data inaccurate
