The manufacturing process of dry-type transformer is very process, and must be technically as a certain pillar. Only in that way,The top and middle of the transformer oil tank, the flange plate,TurkmenistanTypes of dry-type transformers,TurkmenistanPower transformer manufacturer, barrel skin and the middle of the waterproof sleeve at the upper end of the automobile oil tank. The internal iron core and winding clamp are hot due to partial magnetic leakage, resulting in insulation damage.Careless maintenance and insulation damageMogi das Cruzes,When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.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?It will also produce many faults, effectively deal with various faults of oil immersed transformer, make full use of the performance indicators and advantages of oil immersed transformer, and continuously improve the safety factor of oil immersed transformer. Ignition is a common fault of oil immersed transformer. The key fault of oil immersed transformer is short-circuit fault and short-circuit fault is more general.

Protective measures for damping of dry-type transformerHand touch method for transformer inspectionThe main reason is that the welding quality of electric welding is poor, there are empty welding, open 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.Meticulous workmanship,Difference between dry-type transformer and oil immersed transformer:The long-term overload of power transformer will slowly cause the scalding and insulation aging of solenoid coil, resulting in short circuit between coils, two-color short circuit or short circuit on the ground, resulting in the ignition of power transformer. Therefore, the insulation compressive strength of power transformer shall be tested before installation and operation, and overload is not allowed in the whole process of operation.Oil immersed transformer

The time difference between different steps of three-phase power switch of switching power supply shall be less than ms, the closing shall be maintained by high-voltage arrester, and the neutral line of transformer shall be reliably grounded (it shall be grounded immediately).Potential development,Then clamp the branch pipe with your thumb, rotate and release the oil in the tube to clean the sampling tube, carry out it twice, and then draw the oil sample.Overtemperature alarm and trip: collect winding or iron core temperature data signals according to the temperature measurement resistor of PTC discrete system thermistor embedded in the bottom voltage winding. When the transformer winding temperature rises again, if it reaches ℃, the system software outputs the overtemperature alarm system; If the temperature rises to ℃ again and the transformer can no longer operate, the overtemperature trip data signal must be transported to the secondary maintenance circuit, and the transformer shall be tripped quickly.Power transformer factoryTurkmenistan,TurkmenistanTransformer State Grid, seal the flange, and solve the bolts that are likely to leak, so as to achieve the goal of complete treatment. Tighten the loose bolts strictly according to the actual operation and processing technology.What is the wiring mode of dry-type transformer?Oil immersed transformer
