PatanOld box tThe 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.
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.
Clichy.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;
What is the reason for the shutdown of power transformer?

Dry type transformer factory
The flange surface is uneven, the tightening bolts are loose, resulting in oil leakage.
The 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 proper selection of Anhui dry-type transformer has a key effect on improving the safety and smooth operation of power system software. In the above original text so that the bolts are not tightened well,ClichyPower transformer design, we have already mastered the structure and characteristics of dry-type transformer. In this part we will describe how to select dry-type transformer according to the load characteristics and application environment of dry-type transformer.
Oil immersed transformer
property right.The input and output three-phase power lines shall be connected to phase a, phase B and phase C respectively according to the color of yellow, green and red bus duct of transformer terminal board. The zero line shall be connected to the neutral zero line of transformer voltage, and the grounding wire, transformer casing and its transformer point shall be connected to each other. At ordinary times, the transformer box shall be matched with the ground wire mark of the shell and connected with each other). Check the input and output lines to ensure they are appropriate and accurate.
If the volume of power transformer is too small, the transformer will be overloaded for a long time and it is easy to destroy machinery and equipment. Therefore,ClichyRecycling box transformer manufacturer, the rated capacity of the transformer should be selected according to the power consumption, which is not suitable for too large or too small.
Power transformer
When the transformer is put into operation, if the tap changer is not in time, a great & ldquo; Tweet & rdquo; The high-voltage fuse is broken when the noise is serious; If the tap changer is defective, it will cause mild & ldquo; Squeak & rdquo; Corona discharge sound, once the load increases, it is likely to burn the circuit breaker of the tap changer. In case of such situation, power off immediately for maintenance.

The efficiency of transformer is closely related to the output power level of transformer. Generally the greater the output power, the smaller the output power, the lower the efficiency.
The noise of dry-type transformer belongs to low-frequency noise. In a small area, most of it is scattered according to the building structure. This kind of low-frequency noise is scattered to the household house according to the house building, and then causes gas vibration noise, which is then scattered to the ears of consumers. Although the amount of noise is not very large, the dispersion spacing and adverse effects are very large.
Clichy.Before no-load impulse closing, the transformer shall be placed for 24h,ClichyOil immersed box transformer, and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.
Causes of fire in power transformer
Plug in the power with full load first, observe and detect that the input and output voltage meets the regulations. At the same time, check whether the equipment has abnormal sound, ignition, odor and other abnormal conditions. If there is any abnormality, please cut off the input switching power supply.
