Avoid aging and damage of power transformer iron core insulation: aging of iron core insulation or damage of waterproof sleeve holding anchor bolt will cause large vortex of iron core, and long-term scalding of iron core will lead to insulation aging.Before application, the sampling container shall be cleaned with vehicle gasoline, soapy water or other organic solvents (such as trisodium phosphate) except oil stains, and then washed with tap water until it is not alkaline, and the water can be evenly distributed from the bottle, and then cleaned with purified water for many times. The cleaned sampling container shall be dried in a ℃ drying oven. After refrigeration, the bottle cap shall be tightly closed and cannot be opened before application.Rome Lido,The insulation between silicon steel sheets is damaged, resulting in overheating and melting of the iron core;(III) dry type transformers of KVA and below can be installed on poles. The distance between its bottom end and the road surface shall not be less than m; The distance between the electrified part and the road surface shall not be less than m.Auckland metropolitan area,Some are tied with plastic tape, and some immediately press the two edges together, because the socket can not be pressed firmly during installation, so as to reduce the working pressure and leakage. After the leakage location is determined, appropriate surface treatment shall be carried out, and then Fushi blue raw materials shall be selected for sealing treatment.The noise of dry-type transformer is mainly the vibration noise in operation. This vibration noise is caused by multiple positions, including the vibration of magnetic induction electromagnetic coil. All pay great attention to the solution of vibration when carrying out noise control.

The vibration reduction of the grounding device sheet solves the problem of modifying the fixed hard connection between the copper sheet of the grounding device and the dry-type transformer. The original oscillation of the dry-type transformer will be transmitted to the metal in the concrete by the baffle and cause low-frequency noise. Therefore, it must also be changed to produce flexible connection.The person in charge of a transformer manufacturer said that because of the hazards of raw materials and other factors, the cost of energy-saving transformers is significantly higher than that of traditional transformers, and the price factor is also a key factor endangering the popularization and marketing of energy-saving transformers. Although there are energy-saving and convenient subsidy projects to help energy-saving transformers, the market has not yet fully operated.Deterioration damage of transformer core insulationTotal quality assurance,Some are tied with plastic tape, and some immediately press the two edges together because the socket can not be pressed firmly during installation, the tightening bolts are loose and the installation and processing process is wrong, so that the bolts are not tightened well, resulting in oil leakage.Then clamp the branch pipe with your thumb, clearly put forward the glass test tube,Rome LidoFunction of oil immersed transformer, rotate and release the oil in the tube to clean the sampling tube, carry out it twice, and then draw the oil sample.

Power transformer is one of the key equipment in power station and substation. The function of power transformer is in all aspects. It can not only raise the voltage and send electromagnetic energy to the power consumption area, but also reduce the voltage to each application voltage, so as to meet the needs of power consumption. In short,Rome LidoMaintenance price of oil immersed transformer, voltage transformation and blood pressure reduction must be carried out by the transformer.Where is it, the resistance value of the grounding wire shall be measured accurately every two years.Manufacturing process and steps of dry-type transformerRome Lido,Some are tied with plastic tape, and some immediately press the two edges together, because the socket can not be pressed firmly during installation, and there is still oil leakage without sealing effect.Oil immersed transformerWhat is the wiring mode of dry-type transformer?
