after opening the sealing cover, use the cleaned and dried rubber stopper to the oil. At the same time, clamp the branch pipe with your thumb, and loosen your thumb to make the oil enter the pipe,LitvinovAutomatic system of centrifugal fan: measure the temperature data signal according to the PT thermistor temperature measuring resistor of the embedded parts at the hot part of the bottom pressure winding. The transformer load expands and the operating temperature increases. When the winding temperature reaches ℃, the system software automatically starts the centrifugal fan for refrigeration; When the winding temperature is as low as ℃, the system software will automatically terminate the centrifugal fan.When leaving the factory, 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.Toba Tek Singh,Oil leakage of porcelain pot and laminated glass oil level gaugeDuring no-load test run, the transformer shall be connected with the working voltage from the switching power supply side, and then make the working voltage impulse closing.Avoid the load operation of power transformer: if the load operation is long-term, it will lead to the scalding of solenoid coil, slow aging of insulation, short circuit fault between boxes, two-color short circuit fault or short circuit to ground fault and dissolution of oil.

The power transformer belongs to relatively durable electrical equipment,LitvinovMaintenance standard of dry type transformer, power transformer winding and power transformer tapping power switch are analyzed below:The equipment can eliminate the shortcomings found in the patrol inspection, clean the porcelain waterproof casing casing,LitvinovTechnology of oil immersed transformer, remove and replace the cracked or brittle leather pad, check and tighten the node, replenish the oil with less oil, check and replace the silica gel of the breathing mask, etc.Power transformer factoryStandard requirements,The raw materials of Fushi blue can be used for bonding, so that the overall oil leakage of the connector can be greatly controlled; If the actual operation is convenient the metal shell can also be bonded at the same time to achieve the purpose of leakage 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.Power transformer manufacturer

The project cost is different. Compared with the purchase price of capacity transformer, the purchase price of dry-type transformer is much higher than that of oil immersed transformer.Potential developmentThe hanging core of dry-type transformer is a vital partPower transformer is indispensable for power stations and substations, but we must pay attention to many problems in the whole process of applying power transformer.Performance and main parameters of common metal composites, various welding processes and machinery and equipment, preparation treatment of thick steel plate,LitvinovWhat is the starting temperature of dry-type transformer fan, blanking process, production and manufacturing process and quality standards of automobile oil tank, riser, welding leakage test and NDT technology, surface treatment process and quality standards, copper, Production process and quality standard of aluminum shield; Body suit iron insertion process, wire installation process, body dryness solution and dry transformer oil solution process, vacuum pump oil immersion, general installation process, leakage test and leakage detection process and quality standards. Performance parameters of key work clothes, machinery and equipment of each process flow; The natural working environment is basically regulated.Litvinov,The key reason for oil leakage is that there are defects in cast iron partsWhat is the reason for the shutdown of power transformer?Equipped with a temperature controller, platinum thermistor (pt) is placed beside the embedded hole on the top of the low-voltage solenoid coil to test the winding resistance temperature rise of the transformer, stop the cooling centrifugal fan, set up common problem alarm, overtemperature alarm and overtemperature tripping effect, and provide reliable overvoltage protection machinery and equipment for the dry test transformer, so as to test the safety performance of the transformer operation.
