Markham Temper
PatanOld box tIf the above provisions are not met, the problem of dryness shall be solved. Generally,Markham Transformer Daquan, it is OK to operate the centrifugal fan for a period of time. Check the cleanliness of the power transformer. If too much dust is found, it must be eliminated to ensure indoor ventilation and avoid insulation penetration. In particular, pay attention to cleaning the insulators of the power transformer and the top and bottom ends of winding resistance installation. Portable centrifugal fan or dry air compression or N2 shall be used to clean the dust in indoor space that is not easy to reach,Markham Power transformer s13-50, such as ventilation duct, and there shall be no dirt.
The scientific research of power transformer oil is generally carried out according to the way of sampling. What are the common sampling methods and processes?
Markham .The person in charge of a transformer manufacturer said that because of the hazards of raw materials and other factors, 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.
The tap changer of power transformer shall also have strong insulation. 10kV off load tap changer is generally insulated from the ground by the produced insulating paper pipe factory.
.The hanging core of dry-type transformer is a vital part
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.
Before and after sampling, clean the periphery of the sampling port with clean or hairless linen.
For no-load impulse closing of transformer, pay attention to the following matters:
How is the quality level of dry-type transformer compared with foreign countries?
In specific daily life, we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?
Safety production.Then clamp the branch pipe with your thumb, clearly put forward the glass test tube rotate and release the oil in the tube to clean the sampling tube, and then draw the oil sample.
How much is the power transformer
When leaving the factory carry out it twice, the production and processing are not smooth and the sealing is poor. The common fault of oil leakage will be caused after the oil transformer is sealed for a period of time.
The insulation distance between the winding and the iron yoke of power transformer is much larger than that between the windings, because the electric field between the winding and the iron yoke is far away and not as symmetrical as that between the windings. In the electric field in the middle of the winding,Markham High current transformer, most of the cables are in phase with the insulating cylinder (plate) in the middle of the winding, that is, the disconnection component of the electric field is small.
knowledge.The method and whole process of taking oil sample of power transformer are as follows:
After the power transformer has been used for a long time, common faults of iron core will occur. Don't worry. Contact the transformer manufacturer, and the manufacturer will assign professional technicians for inspection. The main reasons are as follows:
After the oil is drained, all anchor bolts of the automobile oil tank at the upper end of the detachable oil cover shall be tied with the lifting jack, and the lifting point shall be on the common earrings or bolts. If necessary, the human resources traction belt shall be used as a guide.
Markham .Oil immersed transformer
The manufacturing process of dry-type transformer is very process, and must be technically as a certain pillar. Only in that way
