Method and process of taking oil sample of power transformer

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.

The hanging core of dry-type transformer is a vital part

Oil leakage at looper flange

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 saving analysis of 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.

device management.The time difference between different steps of three-phase power switch of switching power supply shall be less than 10ms, the closing shall be maintained by high-voltage arrester and the neutral line of transformer shall be reliably grounded (it shall be grounded immediately).

Caused by sand holes and cracks. For crack leakage, drilling stop hole is a good way to remove in-situ stress and prevent widening.

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,PubarTechnology of oil immersed transformer, the cause shall be found immediately and certain effective measures shall be taken. If necessary, the load can be reduced or the operation of the transformer can be stopped.

With the rapid development of society and the continuous development trend of computers,PubarInspection contents of dry-type transformer, the calculation of data in the whole process of oil immersed transformer wave has long had results. Only effective selection of calculation entity models and methods is needed, the accuracy of calculation conclusions can meet the needs of architectural design, and scientific and reasonable data method is selected,PubarTransformer 35KVA, which greatly facilitates the design scheme of the oil immersed transformer and ensures the stability of operation.

Create brilliance.The tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts but also the winding and other structures of the oil immersed transformer can be effectively arranged and distributed in a certain scope, with good strength and stiffness, which is conducive to adjusting the data and has a unique and neat style.

Oil sample inspection & mdash; & mdash; the performance parameters such as compression resistance and residue shall be carried out every three years. The long-term overload or overload of the transformer can reduce the cycle time.

Avoid inadvertent damage of insulation during maintenance: when repairing the hanging core of power transformer, special attention shall be paid to the maintenance of solenoid coil or insulating waterproof sleeve. If there is scratch damage, it shall be handled properly.

Pubar.The voltage regulating tap changer is not in place or poor

Due to poor sealing, generally, the sealing of box edge and machine cover is sealed with acid-base resistant rubber rod or rubber plate. If the joint is not solved well, it will lead to common faults of oil leakage.
