(I) the distance between the external contour of kV and below dry-type transformer and the surrounding guardrail or courtyard wall shall take into account the convenience of transportation and repair of dry-type transformer,RubePrice of 1250kva dry type transformer, and the distance shall not be less than m; At the angle with actual operation a spacing of more than m shall be reserved; If metal fence is selected, the metal fence shall be grounded and a warning sign shall be hung at a prominent position.Power transformer factoryRube,Transformer inspection nose sniffing methodDry type transformer companyDienbian Mansion,The manufacturing process of dry-type transformer is very process, and must be technically as a certain pillar. Only in that way the performance of dry-type transformer will be more stable. What are the common manufacturing processes and steps of dry-type transformer?Dry type transformer oscillation is solved by applying vibration damping platform to dry-type transformer and carrying out low-frequency vibration reduction management,RubeStructure introduction of oil immersed transformer, which can control the oscillation below .%, and then reduce the building structure noise transmitted by dry-type transformer oscillation.The input and output three-phase power lines shall be connected to phase a, phase B and phase C respectively according to the color of yellow, green and red bus duct of transformer terminal board. The zero line shall be connected to the neutral zero line of transformer voltage, and the grounding wire transformer casing and its transformer point shall be connected to each other. At ordinary times, the ground wire and zero wire are led out by the neutral wire of the transformer. (for example, the transformer box shall be matched with the ground wire mark of the shell and connected with each other). Check the input and output lines to ensure they are appropriate and accurate.

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.During the operation of the transformer,RubeOil immersed transformer refueling video, the resistance value of the grounding wire shall be measured accurately every two years.It includes the performance and main uses of insulating layer materials, various insulating layer parts, component manufacturing processes and quality standards; Performance and main uses of various wires, coil inductance process of various ways of electromagnetic coil, solution process and quality standard, overall suit process and quality standard of electromagnetic coil; Main performance parameters of ferrite core, cutting process of iron chip, core stacking process and quality standard, production process and quality standard of electromagnetic shielding.equipment maintenance ,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.When checking the hook core, the insulation of the electromagnetic coil and the porcelain sleeve is usually accidentally damaged. After the shell of the pottery is broken, turn on the photo flash when it's light, and it's short when it's heavy. Therefore, please pay attention during maintenance. It is not necessary to destroy the insulation. After maintenance, experts can inspect special tools, parts, insulation, etc. and deliver them after they are determined to be complete and reliable.Power transformer factory

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.query,The no-load impulse closing working voltage shall not exceed % of the working voltage marked on the gear of the transformer, the closing frequency shall be times, the delay time after power receiving shall not be less than min, and the time interval of each closing shall not be less than min.Once the insulation material of electrical equipment is overheated, you should carefully inspect the equipment and parts until you find out the cause.When we apply oil immersed transformer, we all know that it works with the help of oil. What if the oil immersed transformer is on fire? What countermeasures should we do?Rube,After sampling, cooled by natural air and large capacity by centrifugal fan. Oil immersed transformers are insulated by insulating oil, insulated by insulating oil in the circulating system inside the transformer, and heat is discharged on the radiator (radiator) of the circulating system inside the transformer.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.
