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).Oil leakage of bolt or pipe external threadBelayazelkov,The iron loss of transformer includes two levels. The first is the hysteresis loss introduced by the transformer manufacturer. When the AC circuit is based on the transformer, according to the magnetic induction line of the transformer ferrite core,Belayazelkov35kV energy saving power transformer, its orientation and size change with the change, which promotes the internal molecular structure of the ferrite core to interact with each other, releases energy, and then loses part of electromagnetic energy, which is the hysteresis loss. The other is the vortex loss when the transformer is working.Oil leakage of heat pipe radiatorKyaukse,BelayazelkovMaintenance standard of dry type transformer,The power transformer conductor refers to the connecting transmission line between each electromagnetic coil,BelayazelkovManufacturer of 80 KVA dry type transformer, between the electromagnetic coil and the group outlet pipe, and between the electromagnetic coil and the tap changer.Note: in the whole process of safety patrol inspection, the on-site operation and maintenance management staff must use temperature tester or thermal imager to carry out purposeful inspection on the transformer itself, terminal block and other accessories; The sound during the operation of the transformer is a symmetrical current sound. If the sound is found to be abnormal, significantly expanded, or there is local sound, the load can be reduced or the operation of the transformer can be stopped.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.

In specific daily life, oil immersed transformers are released outward in the form of waves. This kind of wave is like a tide. It is also a kind of kinetic energy. In fact, the wave height of oil immersed transformer also shows the size of kinetic energy. Generally, computer automatic system is used to control the wavelength and frequency of electromagnetic wave. The longer the light wavelength is, the greater the output power is. On the contrary, it is very small.How to make up oil for oil immersed transformer?Manufacturing process and steps of dry-type transformerDesign brand,When sampling from a small and medium-sized power transformer without a discharge pipe (or oil sample suspension plate) it can be in a power transformer such as a glass test tube when it is not in operation to extract the oil sample at the bottom, or it can be replaced by changing the oil.The plastic shells of electrical products and office supplies are equipped with grounding wires. If the insulation layer is damaged and the shell is energized, so as to achieve the purpose of safety, otherwise it will have an adverse impact on life safety.In specific daily life, oil immersed transformers are released outward in the form of waves.

On the contrary, it is very small.

Oil leakage at electric welding positionExecutive standard,The raw materials of Fushi blue can be used for bonding, so that the overall oil leakage of the connector can be greatly controlled; If the actual operation is convenient, the metal shell can also be bonded at the same time to achieve the purpose of leakage treatment.The cycle time of power-off cleaning and inspection shall be determined according to the surrounding environment and load conditions generally from half a year to once a year;Power transformer manufacturerBelayazelkov,The representative mode of connection group of dry-type transformer is: English capital letters indicate the wiring on the primary side (or primary side), and English letters indicate the wiring on the secondary side (or secondary side). Y (or y) is star wiring, and D (or D) is triangular wiring.Turn off the gate valve (butterfly valve) of the left and right tablet computers of the heat pipe radiator to isolate the oil in the heat pipe radiator from the oil in the tank, so as to reduce the working pressure and leakage. After the leakage location is determined, appropriate surface treatment shall be carried out, and then Fushi blue raw materials shall be selected for sealing treatment.The manufacturing process of dry-type transformer is very process, the performance of dry-type transformer will be more stable. What are the common manufacturing processes and steps of dry-type transformer?
