Transformer prevent works in using: 1. Preventing oil leakage: Oil-immersed transformer is filled with transformer oil in the tank, which is sealed by pressing oil-resistant rubber components with fasteners in assembly. Imperfect sealing is the main cause of transformer oil leakage, so special attention should be paid in maintenance and maintenance. Whether the small bolt has been loosened by vibration or not, if loosened, it should be tightened, the tightening degree should be appropriate, and should be consistent everywhere. Whether the rubber is broken or seriously deformed. At this time, the rubber parts can be updated. When replacing, attention should be paid to the consistency of their models and specifications, and keep the sealing surface clean. 2. Preventing dampness of transformer: Transformer is a high-voltage equipment, which requires good insulation performance. Oil-immersed transformer is very susceptible to damp. Preventing damp is one of the main meas...

The aging mechanism of insulating material and factors influencing aging of oil-immersed power transformer are summarized,characteristics of aging mechanism in the courses of thermal aging,electrical aging,mechanical stress and multi- stress aging are concluded. What are the Aging reasons of Oil-immersed Power Transformer? In the long-term operation of transformer, insulation aging will be caused by   electric field, moisture, temperature and mechanical force . Oil-immersed transformer tank manufacturing Oil-immersed Power Transformer Life assessment Polymerization degree (DP) of transformer insulation material is the most accurate, reliable and effective criterion for insulation aging degree. According to the average degree of polymerization of insulated cardboard to judge the aging degree of transformer, we adopt the following criteria. Evaluation Criteria of Average Polymerization Degree of Insulating Paper Classified   life-level   ...

The advantage & disadvantage of Transformer Oil list follows: Transformer Oil Advantage: 1. Transformer cooling oil has good insulation performance, good thermal conductivity and low cost. 2. It can solve the problem of large capacity heat dissipation and high voltage insulation of transformer. Transformer cooling Oil Disadvantages: 1. Transformer cooling oil is flammable and may burn and explode when it comes to flame. 2. Transformer cooling oil is harmful to human body 3. Transformer cooling oil should be inspected regularly 4. Oil-immersed transformer has poor sealing performance and is suitable for aging. Oil leakage is serious in the operation place, which affects the safe operation of equipment and the environment at the same time. 5. Oil-immersed transformer with low insulation grade is designed and manufactured according to class A insulation. How the oil immersed transformer to cool the oil? 1.By transformer radiator transformer radiator 2.By...

Transformer Cooling Oil treatment methods: 1.   Pressure filtration method:   Insulating oil for power transformer must have insulation and thermal conductivity (national standard) at the installation site. Pressure filtration method is commonly used to complete the general drying (removing moisture) and purification (removing dirt) of insulating oil. 2. Open valves 8 and 11, then start the oil pump, and then open valves 6 and 7. When shutting down, shut down 6 and 7 first, then shut down the oil pump, and then shut down the valves of 8 and 11. In normal operation, the pressure gauge works normally under the pressure of 3*10~4*10 Pa. If impurities and oil paper are blocked, the pressure will increase. When the pressure reaches 6*10 Pa, the filter paper must be stopped and replaced. The filter paper is dried for 24 hours in an oven at 80-90℃ before use and placed in a clean container. The filter screen is cleaned every 10-15 hours. At the beginning, the oil is filter...
