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.Oil immersed transformer companyvictoria,There is a magnetic induction line crossing in the transformer core, which will cause induced electromotive force on the plan with the magnetic induction line. Because this electric flow creates a closed loop to generate an electric field and forms a vortex, it is called vortex. The existence of vortex makes the transformer core hot and consumes kinetic energy. This kind of loss is called vortex loss.Avoid aging and damage of power transformer iron core insulation: aging of iron core insulation or damage of waterproof sleeve holding anchor bolt will cause large vortex of iron core,victoriaParameters of 500 KVA oil immersed transformer, and long-term scalding of iron core will lead to insulation aging.Barcelona,Deterioration damage of transformer core insulationFor example,victoria1600KVA transformer price, in the s, the radio programs applied by every family in the countryside had a ground wire, and they were often wet with tap water. Protective grounding is to bury the copper plate of metal electrical conductor in the soil layer, and then lead a point of it out of the road with transmission line, office and other electrical equipment.Performance and main parameters of common metal composites various welding processes and machinery and equipment, preparation treatment of thick steel plate, blanking process, production and manufacturing process and quality standards of automobile oil tank, riser, coupling and oil storage tank cabinet, 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.

Dry type transformer oscillation is solved by applying vibration damping platform to dry-type transformer and carrying out low-frequency vibration reduction management, which can control the oscillation below .%,victoriaDry type transformer production process, and then reduce the building structure noise transmitted by dry-type transformer oscillation.The grounding resistance of, high voltage and bottom voltage shall not be less than % (m & omega;) of the original value. The difference between the three-phase mean value of winding resistance measurement at the same temperature shall not exceed % which shall not exceed % compared with the last accurate measurement result.For the installation of lightning rod, it is very easy to damage the relay protection inside and outside of dry-type transformer by lightning. If it is a serious situation, it is very easy to cause fire accidents, power failure, damage to machinery and equipment, etc.target,Power transformer manufacturerSome are tied with plastic tape, and some immediately press the two edges together, because the socket can not be pressed firmly during installation, and there is still oil leakage without sealing effect.Falling foreign matters and piercing

The tap changer of power transformer shall also have strong insulation. kV off load tap changer is generally insulated from the ground by the produced insulating paper pipe factory.plan, it is necessary to carry out voltage transformation and blood pressure reduction according to the transformer to reduce the loss of electromagnetic energy in the whole process. Therefore, which is converted into bottom voltage electromagnetic energy through transformer.If the power transformer stops running for more than h (if the allowable time should be reduced when the ambient humidity is & amp; gt; %), it should be insulated before putting into use, and accurately measured with a V grounding megger. The insulation resistance from the primary side to the secondary side and the ground should be ^ mfl, the insulation resistance from the secondary side to the ground should be ^ mh, and the insulation resistance from the iron core to the ground should be & amp; gt; mfl (note that the grounding device piece should be removed).victoria,Some are tied with plastic tape, and some immediately press the two edges together, because the socket can not be pressed firmly during installation, and there is still oil leakage without sealing effect.The oil in the machinery and equipment of the oil storage tank shall generally stand for more than h before sampling; it is not necessary to stand when sampling on the running power transformer.Noise solution of dry-type transformer
