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.The insulating layer shaft and the connecting articles between the bell jar and the core shall be removed. If it is a hanging bell inspection, the oil shall be pumped into the bottom of the bell jar before the bell jar can be removed.Minas,The dry-type transformer used for power plant voltage transformation is different from the oil transformer. It is strictly prohibited to lead the way at the bottom voltage side to prevent the insulation layer of the dry-type transformer from penetrating due to overvoltage caused by overvoltage at the power grid side or lightning stroke on the line.During 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.SkalicaAccording to the condition of cracks, the anchor bolt cover with the iron core is damaged galvanized iron wire can be punched into the leakage or riveted with hammer. Then clean the leakage point with toluene and seal it with raw materials. Coated sand casting eyes can be sealed with raw materials immediately.The insulating layer in the middle of the silicon steel plate is aging, the iron core causes large vortex, resulting in heat, temperature rise, and the aging of the insulating layer is accelerated. The core insulation compressive strength of power transformer must be measured on time and accurately. If it is found that the insulation compressive strength is less than the index value, please remove and replace the anchor bolt cover or carry out insulation for the copper core cable.Noise solution of dry-type transformer

Power transformer is one of the key equipment in power station and substation. The function of power transformer is in all aspects. It can not only raise the voltage and send electromagnetic energy to the power consumption area, but also reduce the voltage to each application voltage, so as to meet the needs of power consumption. In short, voltage transformation and blood pressure reduction must be carried out by the transformer.The visual inspection method is that the staff use human eyes to observe the appearance change of the visible parts of the operating equipment to find the abnormal conditions of the equipment, such as discoloration, deformation, offset,MinasDistribution transformer experiment, cracking, loosening, ignition smoke,MinasPrice of 800kVA distribution transformer, oil leakage, broken strand disconnection, short-circuit fault marks, hanging of dirty things, etching and turbidity, which can be inspected according to the visual inspection method. Therefore, visual inspection is one of the common methods of equipment inspection.After no-load test run is normal for h, and the load shall be gradually increased from %, % and % by grade.Supply chain quality management,On load commissioning:If the volume of power transformer is too small, the transformer will be overloaded for a long time and it is easy to destroy machinery and equipment. Therefore, the rated capacity of the transformer should be selected according to the power consumption,Oil leakage of bolt or pipe external threadThe person in charge of a transformer manufacturer said that because of the hazards of raw materials and other factors, the cost of energy-saving transformers is significantly higher than that of traditional transformers, and the price factor is also a key factor endangering the popularization and marketing of energy-saving transformers. Although there are energy-saving and convenient subsidy projects to help energy-saving transformers the market has not yet fully operated.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.Minas,Noise solution of dry-type transformerPower transformer is an idealized supporting facility transformer for medium cabinet and high-voltage cabinet at the present stage, and can be equipped with safety protective casing according to different waterproof grades. It is applicable to key or unique natural environment sites such as multi-storey buildings, airports,MinasLoss table of distribution transformer, tunnel construction, chemical enterprises and factories.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.
