Power 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.Equipped with a temperature controller, platinum thermistor (pt) is placed beside the embedded hole on the top of the low-voltage solenoid coil to test the winding resistance temperature rise of the transformer, stop the cooling centrifugal fan, set up common problem alarm,AlcabidPower transformer customization, overtemperature alarm and overtemperature tripping effect, and provide reliable overvoltage protection machinery and equipment for the dry test transformer, so as to test the safety performance of the transformer operation.Alcabid,Maintenance contents of power transformerIt is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials, porcelain, laminated glass and other materials very well, so as to achieve the pressure management of oil leakage.Sanarate,(II) the height width ratio of dry-type transformer pier installed on the ground is generally .m, and a guardrail of no less than m shall be installed around it and a warning sign shall be hung at a prominent position.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?Deterioration damage of transformer core insulation

For no-load impulse closing of transformer, pay attention to the following matters:The secondary inductive equipment of the distribution station (such as transformer, voltage transformer, automobile relay, AC, etc.) operates normally. According to the AC current, the winding transformer core will send out a symmetrical rhythm and a certain tone & ldquo; Buzz, buzz & rdquo; Sound. The operation staff of the transformer manufacturer should understand and grasp the characteristics of the noise. When the equipment has common faults, there will be noise and even & ldquo; Crackle & rdquo; The charging and discharging sound can distinguish the generation and characteristics of common equipment faults according to the music law and sound transformation when everything is normal and abnormal.What is the wiring mode of dry-type transformer?original, commerce, tunnel construction, chemical enterprises and factories.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?

Caused by sand holes and cracks. For crack leakage, drilling stop hole is a good way to remove in-situ stress and prevent widening.details,The scientific research of power transformer oil is generally carried out according to the way of sampling. What are the common sampling methods and processes?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.(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, a spacing of more than m shall be reserved; If metal fence is selected and the distance shall not be less than m; At the angle with actual operation,AlcabidThe dry-type transformer is good, the metal fence shall be grounded and a warning sign shall be hung at a prominent position.Alcabid,Due to careless transportation of the transformer and the thin high-voltage conductor, the transformer was disconnected by vibration (but there was no grounding device).Operation and maintenance management of oil immersed transformerPower transformer manufacturer
