Sound,PavloglerPower supply high frequency transformer,Pavlogler10kV dry type transformer test,PavloglerHow much is a 250kVA box transformer, causing short circuit obstruction. If not handled properly, it will cause great damage.Power transformer factoryPavlogler,The common dry-type transformer is an important electrical equipment, and the voltage is constantly regulated. However, because of certain necessity, the dry-type transformer will also boost voltage, and the whole process of boosting voltage is very complex, and there are many principles.Fault judgment of power transformerUddevalla,The power transformer conductor refers to the connecting transmission line between each electromagnetic coil, between the electromagnetic coil and the group outlet pipe, and between the electromagnetic coil and the tap changer.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 data signal circuit of steam vehicle relay shall be temporarily connected to the pull-in circuit.Transformer manufacturerIf the power transformer stops running for more than h (if the allowable time should be reduced when the ambient humidity is & amp; gt; %) the pose period of overcurrent protection shall be set to zero, 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).resources,Solenoid insulation deteriorationWhat is the reason for the shutdown of power transformer?Difference between dry-type transformer and oil immersed transformer:

In order to better reduce the probability of short-circuit fault of relay protection dry-type transformer, prevention and key are & ldquo; Prevention and Manipulation & rdquo; Is dominant.Customer first,Causes of fire in power transformerThe rate of transformer is: n = P / pxo%, that is, when the copper loss of transformer is equivalent to iron loss, the rate is very large. Therefore, Generally, it is about %, but when selecting the transformer capacity we should select effective transformers according to the load condition and load, so as to make the transformer in the situation of economic development and achieve the goal of power saving.If the above provisions are not met, the problem of dryness shall be solved. Generally, it must be eliminated to ensure indoor ventilation and avoid insulation penetration. In particular, pay attention to cleaning the insulators of the power transformer and the top and bottom ends of winding resistance installation. Portable centrifugal fan or dry air compression or N shall be used to clean the dust in indoor space that is not easy to reach, such as ventilation duct, and there shall be no dirt.Pavlogler,The key reason for oil leakage is that there are defects in cast iron partsWhat about oil immersed transformer fire?What is the wavelength of oil immersed transformer?
