OstholtS13 oil immersed transformerUpgrade to intelligence

Solenoid insulation deteriorationPower 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,Power saving analysis of transformers has always been based on whether the utilization rate of transformer capacity is less than a certain standard value. Whether transformers are environmental protection and energy saving specifications. In fact, sometimes such specifications are not saving electromagnetic energy, but consuming electromagnetic energy.In specific daily life, we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?Leon,The whole process of hanging the core of dry-type transformer is more critical, and there are many situations that the hanging core of dry-type transformer must pay special attention to. Therefore,OstholtOil immersed transformer manufacturer, the hanging core of dry-type transformer should be carried out according to the above matters, so as to promote the safety of dry-type transformer!Connection group structure of dry-type transformerThe method and whole process of taking oil sample of power transformer are as follows:

The power transformer is composed of two or more electromagnetic coils wound around the same transformer core. The winding resistance is connected according to the alternating electromagnetic field and works according to the basic principle of magnetic effect of current. The installation position of power transformer shall be considered to be conducive to operation,OstholtDry type transformer scb14, maintenance and transportation, and a reliable area shall be selected at the same time. The rated capacity of the transformer must be effectively used when applying the transformer.Principle of step-up dry-type transformer: the step-up dry-type transformer is a component that correspondingly converts low communication AC voltage, large current flow and small characteristic impedance into high communication AC voltage, small current and large characteristic impedance. When there is an AC circuit in the original coil, the communication AC magnetic flux will be caused in the transformer core (or magnetic core), causing the magnetic induction voltage in the primary coil (or current).Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;index,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.Method and process of taking oil sample of power transformer(IV) the transformer on the column shall be stable and firm, and the waist rail shall be & phi; mm galvanized wire shall be wound over turns in an even number. The iron wire shall not have a connector and shall be tightened after winding. The distance between the waist rail and the energized part shall not be less than .m.

Some are tied with plastic tape, and some immediately press the two edges together, because the socket can not be pressed firmly during installation, and there is still oil leakage without sealing effect.Recommendation and consultationThe tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts, with good strength and stiffness, if it reaches ℃, the system software outputs the overtemperature alarm system; If the temperature rises to ℃ again and the transformer can no longer operate, and the transformer shall be tripped quickly.If the above provisions are not met, the problem of dryness shall be solved. Generally, it is OK to operate the centrifugal fan for a period of time. Check the cleanliness of the power transformer. If too much dust is found, 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.Ostholt,OstholtOn load voltage regulation of power transformer,When leaving the factory, the production and processing are not smooth and the sealing is poor. The common fault of oil leakage will be caused after the oil transformer is sealed for a period of time.Power transformer plantThe 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.
