SosnoikS13 oil immersed transformerWhat checks should be done before use

Operation of oil immersed transformerCaused by sand holes and cracks. For crack leakage drilling stop hole is a good way to remove in-situ stress and prevent widening.Sosnoik,Transformer manufacturerThe sampling container is a colorless glass bottle with a wide mouth ground glass plug with a volume of .kg or kg. - bottles shall be collected at a time for analysis and experiment. Labels shall be attached during sampling. Pay attention to the name, source, sampling date, sampling person, weather conditions and other materials of the oil sample.Bockla,After hours of continuous trial operation with a certain load, the main body and accessories of the transformer are all normal, and the transformer will turn to all normal operation.Oil immersed transformer companyThere are many connection groups of dry-type transformers, and the selected structures and connections are also different. Then, what are the groups of dry-type transformers? How to carry out the connection? Or basically introduce it with the network of dry-type transformer manufacturers.

Therefore, in the operation prevention and regulation of relay protection dry-type transformer, it is necessary to find the short-circuit fault point according to the fault situation, lock the fault point, and analyze the short-circuit fault types of relay protection dry-type transformer. At the same time, if all fields are clear, disconnect the switching power supply at the fault point, the maintenance work of employees will be carried out smoothly, and the harm will not expand to a greater extent.The insulation between silicon steel sheets is damaged, resulting in overheating and melting of the iron core;After no-load test run is normal for h, it can be transferred to on-load operation, and the load shall be gradually increased from %, it is very easy to damage the relay protection inside and outside of dry-type transformer by lightning. If it is a serious situation, power failure damage to machinery and equipment, etc.It is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials, porcelain, laminated glass and other materials very well, so as to achieve the pressure management of oil leakage.Wiring mode of dry-type transformer:

Power transformer plantLatest consultation,The capacity and working voltage are different. The dry-type transformer is generally suitable for distribution equipment. The capacity is generally below kVA and the working voltage is below KV,SosnoikBox type transformer 400kV,SosnoikDifference between power transformer and dry-type transformer, which also ensures the rated voltage of kV; Oil immersed transformers are generally suitable for distribution equipment.The transformer manufacturer will introduce the efficiency of the transformer to youPower transformers are used in all walks of lifeSosnoik,The clock expression is used to indicate the phase difference correlation of the working voltage of the secondary side line. The phasor of the working voltage of the primary side line is used as the minute hand, the fixed finger is at o'clock and the phasor of the phase voltage of the secondary side is used as the second hand.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,SosnoikHow much is a dry-type 1250 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 conductor insulation of power transformer is the main part of internal insulation. Some conductors should pass through the middle of electromagnetic coil, or between electromagnetic coil, iron yoke clamp and automobile oil tank wall. Therefore, it is necessary to ensure that this kind of conductor has sufficient insulation compressive strength, i.e. insulation spacing.
