San JuanWhat dThe tap changer of power transformer shall also have strong insulation. 10kV off load tap changer is generally insulated from the ground by the produced insulating paper pipe factory.
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?
San Juan de la maguana.Several detection methods for installing transformer
It includes the performance and main uses of insulating layer materials, various insulating layer parts,San Juan de la maguana1000 dry type transformer size, component manufacturing processes and quality standards; Performance and main uses of various wires, coil inductance process of various ways of electromagnetic coil, solution process and quality standard, overall suit process and quality standard of electromagnetic coil; Main performance parameters of ferrite core, cutting process of iron chip, core stacking process and quality standard, production process and quality standard of electromagnetic shielding.
.The vibration reduction of the grounding device sheet solves the problem of modifying the fixed hard connection between the copper sheet of the grounding device and the dry-type transformer. The original oscillation of the dry-type transformer will be transmitted to the metal in the concrete by the baffle and cause low-frequency noise. Therefore, it must also be changed to produce flexible connection.
Solenoid insulation deterioration
In fact, ground wire is not only a kind of grounding protection. The following describes in detail that ground wire is the general name of grounding system. Ground wire is divided into protective grounding and safety factor grounding device. Among them, safety factor grounding device can be divided into grounding protection, anti electric shock grounding device and anti electromagnetic wave radiation grounding device. Protective grounding is to use it for loop to make the facilities achieve the grounding wire specified by the function.

Several detection methods for installing transformer
A zero line of the power transformer is connected with the working equipment. Since the voltage formed by the server during operation will be sent to the power transformer along with the cable, the purchase price of dry-type transformer is much higher than that of oil immersed transformer.
Protective measures for damping of dry-type transformer
For the leakage that has already occurred the purchase price of dry-type transformer is much higher than that of oil immersed transformer.
The project cost is different. Compared with the purchase price of capacity transformer find the leakage point first, which can not be ignored. For the position with serious leakage,San Juan de la maguanaPrice of 1000 KVA transformer, shovel or sharp punch can be selected. The leakage point can be riveted with special tools for metal materials. After manipulating the leakage, the treatment surface shall be cleaned and tidy. Polymer composite materials are mostly selected for dry consolidation. After dry consolidation,San Juan de la maguana220 kV Transformer, the goal of long-term treatment of leakage can be achieved.
Total quality management.The main reason is that the welding quality of electric welding is poor, there are empty welding, open welding, needle holes, sand holes and other shortcomings in welding. The oil transformer is easy to be covered with welding powder and paint when leaving the factory, and the potential safety hazards are exposed after operation. In addition, the electromagnetic induction vibration will crack the electric welding and lead to leakage.
Visual inspection method for transformer inspection
Naturally, if the oil immersed transformer catches fire, please don't panic. I firmly believe that the damage will be reduced to a lower level as long as the above methods are effectively rectified. Above is the general process and process that should be paid special attention to in the whole ignition process of the oil immersed transformer. When the oil immersed transformer catches fire, please be rational to make the oil immersed transformer safer and more efficient.

Before and after sampling, the transformer was disconnected by vibration (but there was no grounding device).
