When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.The main reason is that the welding quality of electric welding is poor, there are empty welding, needle holes, sand holes and other shortcomings in welding. The oil transformer is easy to be covered with welding powder and paint when leaving the factory, and the potential safety hazards are exposed after operation. In addition the electromagnetic induction vibration will crack the electric welding and lead to leakage.Kalyan ,Kalyan Model of 35kV dry type transformer,Power transformer is indispensable for power stations and substations, but we must pay attention to many problems in the whole process of applying power transformer.Careless maintenance and insulation damageRio Tercero,Oil immersed transformer operationWhen sampling in bulk gasoline barrels, samples shall be selected according to % of the number of gasoline barrels, but not less than barrels. When sampling in batches of small and medium-sized pails or bottles, samples shall be taken according to % of the total number of barrels (bottles).A specific part of dry-type transformer is the hanging core of dry-type transformer. The hanging core of dry-type transformer is a vital component. How to carry out the hanging core?

The project cost is different. Compared with the purchase price of capacity transformer,Kalyan Substation transformer,Kalyan Power transformer insulation, the purchase price of dry-type transformer is much higher than that of oil immersed transformer.The grounding resistance of, high voltage and bottom voltage shall not be less than % (m & omega;) of the original value. The difference between the three-phase mean value of winding resistance measurement at the same temperature shall not exceed %, which shall not exceed % compared with the last accurate measurement result.Dry type transformer companyproduction costs,Falling foreign matters and piercingAnalysis of common faults of oil immersed transformer:Fault judgment of power transformer

Seal oil leakageTrustworthy,After the test, connect the data signal contact of the automobile relay with the alarm circuit, the pull-in contact with the opening circuit, and adjust the overcurrent protection value.The transformer manufacturer shall not use hand touch method to detect energized high-voltage equipment, such as transformer in operation and neutral grounding equipment of arc suppression coil. For the equipment without power supply and whose shell is reliable grounding device, the temperature or temperature rise must be tested by hand. The secondary equipment can be inspected by hand touch method when it is hot and vibrated.Before and after sampling, clean the periphery of the sampling port with clean or hairless linen.Kalyan ,& ldquo; YN, D & rdquo;, in which indicates that when the working voltage phasor of the primary side line as the minute hand, refers to the position at o'clock, the phase voltage phasor of the secondary side is at o'clock. That is, the phase voltage UAB of the secondary side lags degrees behind the working voltage uab of the primary side line (or degrees ahead).How much is the power transformerThe insulation distance between the winding and the iron yoke of power transformer is much larger than that between the windings, 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.
