After tightening the loose bolts, 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.Note: in the whole process of safety patrol inspection, the on-site operation and maintenance management staff must use temperature tester or thermal imager to carry out purposeful inspection on the transformer itself, terminal block and other accessories; The sound during the operation of the transformer is a symmetrical current sound. If the sound is found to be abnormal, significantly expanded, or there is local sound, the cause shall be found immediately and certain effective measures shall be taken. If necessary, the load can be reduced or the operation of the transformer can be stopped.Ostholt,Step up process of dry-type transformer?When the full load test is carried out and everything is normal, the load can be connected.Catacocha,Ostholt315 box type transformer,Noise dispersion of dry-type transformerOn load commissioning: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 dispersion of dry-type transformerTransformer manufacturers said that at this stage, China's energy-saving distribution transformer market is relatively scattered, coupled with the constraints of factors such as low threshold in the field, uneven companies, lack of evaluation and specifications, and inadequate technical innovation, resulting in slow marketing of energy-saving transformers.The whole process of hanging the core of dry-type transformer is more critical and there are many situations that the hanging core of dry-type transformer must pay special attention to. Therefore, the hanging core of dry-type transformer should be carried out according to the above matters, so as to promote the safety of dry-type transformer!Supply chain quality management, bind the laminated glass stopper firmly with clean paper or cloth to prevent dirt and water from contaminating the bottle stopper.Caused by sand holes and cracks. For crack leakage, drilling stop hole is a good way to remove in-situ stress and prevent widening.

Power transformer plantquality,The vibration reduction of the grounding device sheet solves the problem of modifying the fixed hard connection between the copper sheet of the grounding device and the dry-type transformer. The original oscillation of the dry-type transformer will be transmitted to the metal in the concrete by the baffle and cause low-frequency noise. Therefore, it must also be changed to produce flexible connection.Under normal conditions, different oil-based oils cannot be mixed. Under special circumstances, if it is necessary to use new oil of different grades,OstholtScb10 dry type distribution transformer, 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 oil 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, power supply bureaus and scientific research institutions. According to the specifications of the Bureau of quality supervision,OstholtHigh overload capacity distribution transformer, It is used to carry out insulation compressive strength test under required current for various electrical products, electrical components and insulating raw materials.Ostholt, it must also be changed to produce flexible connection.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.What is the important role of power transformer
