The insulating layer in the middle of the silicon steel plate is aging, the anchor bolt cover with the iron core is damaged, the iron core causes large vortex, temperature rise, and the aging of the insulating layer is accelerated. The core insulation compressive strength of power transformer must be measured on time and accurately. If it is found that the insulation compressive strength is less than the index value, please remove and replace the anchor bolt cover or carry out insulation for the copper core cable.Manufacturing process and steps of dry-type transformerBaltimore,The transformer manufacturer said that the temperature display equipment: the temperature change value is measured according to the PT temperature sensor embedded in the bottom voltage winding to immediately indicate the winding temperature of each phase (three-phase safety inspection and Zui large value indication,BaltimoreSupply transformer, and the historical time Zui high temperature can be recorded). The Zui high temperature can be input and output as mA analog quantity. If it is to be far away (the distance can reach m the electronic computer can be equipped with an electronic computer socket, an intelligent transmitter, and transformers can be detected. The over temperature alarm and trip of the system software can also be signaled by the resistor data of Pt thermistor sensor, so as to further improve the stability of the temperature maintenance system software.Careless maintenance and insulation damageChimkent,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?Power transformer plantThe 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.

When the new oil filled by the power transformer and the oil sample that has just been considered are used, the oil sample can be used only after sufficient standing.The selection shall be carried out according to the load characteristics of power. There are many types of power loads. Different dry-type transformers shall be used for different power loads. If the standard impulse level of power load is less than kV, class H dry-type transformers shall be used. If the standard impulse level of power load exceeds kV, epoxy resin adhesive shall be used to pour dry-type transformers.The input and output three-phase power lines shall be connected to phase a, 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.Safety and health,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.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.Noise solution of dry-type transformer

Caused by sand holes and cracks. For crack leakage, drilling stop hole is a good way to remove in-situ stress and prevent widening.technical service,Sound,BaltimoreThe dry-type transformer is good,BaltimoreDistribution transformer wiring group, causing short circuit obstruction. If not handled properly, it will cause great damage.The dry-type transformer used for power plant voltage transformation is different from the oil transformer. It is strictly prohibited to lead the way at the bottom voltage side to prevent the insulation layer of the dry-type transformer from penetrating due to overvoltage caused by overvoltage at the power grid side or lightning stroke on the line.Seal oil leakageBaltimore,Falling foreign matters and piercingMethod and process of taking oil sample of power transformerOil leakage of porcelain pot and laminated glass oil level gauge
