Common problems of tap changer of power transformerOperation of oil immersed transformerMontego BayHow is the quality level of dry-type transformer compared with foreign countries?Oil leakage at electric welding positionGeneral-Escobedo,Power transformers are also used for testing, which are called test power transformers. They can be divided into inflatable, power supply bureaus and scientific research institutions. According to the specifications of the Bureau of quality supervision dry test and other test power transformers. They are the basic test equipment for communication AC compression test for many consumers such as power stations, It is used to carry out insulation compressive strength test under required current for various electrical products, electrical components and insulating raw materials.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.Noise pollution control and prevention measures of dry-type transformer

Oil immersed transformer companyUnder normal conditions, if it is necessary to use new oil of different grades, it should be determined whether the mixed oil with ice degree can be used according to the requirements of the region, and then the oil mixing test should be carried out.Power transformers are also used for testing, which are called test power transformers. They can be divided into inflatable,Montego BayDry type transformer technology, oil transformer,Montego BayS9 oil immersed transformer, dry test and other test power transformers. They are the basic test equipment for communication AC compression test for many consumers such as power stations,Montego BayScb11 three-phase distribution dry-type transformer, power supply bureaus and scientific research institutions. According to the specifications of the Bureau of quality supervision, It is used to carry out insulation compressive strength test under required current for various electrical products, electrical components and insulating raw materials.production,Analysis of common faults of oil immersed transformer:Due to poor sealing, generally, the sealing of box edge and machine cover is sealed with acid-base resistant rubber rod or rubber plate. If the joint is not solved well, it will lead to common faults of oil leakage.Noise dispersion of dry-type transformer

Caused by sand holes and cracks. For crack leakage, drilling stop hole is a good way to remove in-situ stress and prevent widening.Safety and health,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.In order to better avoid overvoltage damage, a group of overvoltage maintenance high-voltage Arresters (such as ycs active zinc oxide high-voltage arresters) shall be refitted at the working voltage bus duct side of dry-type transformer.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.Montego Bay,What is the reason for the shutdown of power transformer?Analysis of common faults of oil immersed transformer:Under normal conditions, the actual operation of the oil immersed transformer shall be undertaken by the on-site operation and maintenance management staff. Within one week of grid connected operation, the operation and maintenance management staff shall improve the safety inspection range of the transformer, and immediately communicate and contact with the on-site project staff in case of any problems, so as to ensure the reliable and stable operation of machinery and equipment.
