Oil Immersed Transformerhas good insulation performance, good thermal conductivity, and at the same time，the Transformer oil is cheap. Moreover, Oil Immersed Transformer can solve the problem of large-capacity heat dissipation and high-voltage insulation of Transformers.
How to check Oil Immersed Transformer?
What are the installation requirements for oil-immersed Transformers?
What should I do if the Oil Immersed Transformer radiator leaks oil?
1. After the Transformer is transported for a long distance, it will be subject to greater vibration and needs to be inspected. The Transformer body inspection is divided into hanging core and hanging cover. Regardless of the hanging core or the hanging cover, the inspection content is the same. The hanging core inspection should be completed within one working day to speed up the inspection process.
2. Take the hanging core inspection as an example: ⑴The Transformer hanging core should be carried out indoors. If there should be a tent outdoors, it is forbidden to hang the core in severe weather such as rain, snow, heavy fog, wind and sand. ⑵The temperature of the hanging core in winter should not be lower than zero degrees, otherwise the temperature of the Transformer should be increased to make the core temperature 10℃ higher than the surrounding temperature. The shorter the time the core is exposed to the air, the better, and the relative humidity should not exceed 16 hours when the relative humidity is 65%. The relative humidity should not exceed 12 hours when the relative humidity is 25%. The calculation time is from the beginning of the oil drain to the oil filling. ⑷When the relative humidity of the weather exceeds 75%, the core hanging inspection is not allowed. ⑸In the process of lifting core inspection, pay special attention to prevent parts and tools from falling into the oil tank.
1. The Transformer foundation track should be level, and the oil pillow side should have a slope of 1-1.5%.
2. The Transformer should be reinforced.
3. The primary and secondary leads of the Transformer should not force the bushing.
4. The Transformer shell is firmly connected with the neutral point and the grounding device to form a trinity.
The heat pipe of the radiator is usually flattened with seamless steel pipes and then punched. Oil baggage often occurs in the curved and welded parts of the heat pipe. This is due to the fact that when the heat pipe is punched, the outer wall of the pipe is under tension and the inner wall is under pressure. Caused by self-tension. Close the top and bottom plate valves (throttle valves) of the cooler to isolate the oil in the cooler from the oil in the tank and reduce the pressure and leakage. After determination of the leakage system, appropriate surface treatment is carried out.
The installation of Oil Immersed Transformer can effectively solve some of the difficulties that occur in the process of using electricity. Zhejiang Zhegui Electric Co., Ltd has been committed to provide the perfect Oil Immersed Transformer for every customer from all countries.
