Clement FerrandWorking principle of power transformerThe overall stabilization of the market

In the whole process of transmitting electromagnetic energy in the power supply system, it will inevitably cause the loss of voltage and output power. When transporting the same output power, the voltage loss is inversely proportional to the voltage, and the output power loss is inversely proportional to the square meter of voltage. The transformer is used to increase the voltage and reduce the closing damage.Caused by sand holes and cracks. For crack leakage, drilling stop hole is a good way to remove in-situ stress and prevent widening.Clement Ferrand,Precautions for trial operation of power transformer manufacturersIn the whole process of transmitting electromagnetic energy in the power supply system, it will inevitably cause the loss of voltage and output power. When transporting the same output power, the voltage loss is inversely proportional to the voltage, and the output power loss is inversely proportional to the square meter of voltage. The transformer is used to increase the voltage and reduce the closing damage.Zhytkavichy,Causes of fire in power transformerFor kVA power engineering transformer, plastic parts are selected in the middle of iron core, clean the periphery of the sampling port with clean or hairless linen.

In the electric field of the winding to the yoke, there must be a strong line breaking component, so that sliding flash charge and discharge may occur at a lower current. In order to better solve this disadvantage the appearance of the insulating parts between the winding and the iron yoke should be the same as that of the medium horizontal plane of the winding to the iron yoke insulation as far as possible,Clement FerrandPower transformer function, so as to reduce the electric field component intersecting with the insulating parts.Protection mode for type selection of dry-type test transformerPower 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.Click to view,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.Power transformer manufacturerBefore no-load impulse closing, the transformer shall be placed for h, and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.

What about oil immersed transformer fire?Installation works,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 %, % and % by grade.How to make up oil for oil immersed transformer?Oil leakage at looper flangeClement FerrandIf the oil immersed transformer is burned by the cover of the transformer, when the oil immersed transformer fails,Clement FerrandOutdoor dry-type transformer structure, open the lower side of the transformer and place an appropriate part. When the oil immersed transformer is on fire, the oil cannot be released to avoid the occurrence of the oil immersed transformer. At the same time, use detection equipment to put out the fire immediately. In order not to expand the hazard, the fire brigade must be notified.kV and above & plusmn; No load of rated voltage; Part of the circuit breaker of the tap power switch is installed in the phenolic resin insulating paper cylinder
