MahendranagaHoAfter 24 hours of continuous trial operation with a certain load, the main body and accessories of the transformer are all normal, and the transformer will turn to all normal operation.
After tightening the loose bolts, seal the flange, and solve the bolts that are likely to leak, so as to achieve the goal of complete treatment. Tighten the loose bolts strictly according to the actual operation and processing technology.
Baikonil.According to statistics, to occupy the main global technical position, the transformer industry depends on two key data, commodity volume and voltage level. As early as & ldquo; Eleventh Five Year Plan; In the early stage China has been a powerful country in the production, manufacturing and application of dry-type transformers all over the world, but it is not a big country.
Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;
.When the manufacturer of the power transformer samples from the automobile oil tank, after opening the sealing cover, use the cleaned and dried rubber stopper to the oil. At the same time, clamp the branch pipe with your thumb, and loosen your thumb to make the oil enter the pipe,
Avoid inadvertent damage of insulation during maintenance: when repairing the hanging core of power transformer,BaikonilSpot inspection standard for dry type 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.
In specific daily life, the wave height of oil immersed transformer also shows the size of kinetic energy. Generally,BaikonilModel of power transformer, 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.
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?
The efficiency of transformer is closely related to the output power level of transformer. Generally, the greater the output power, the smaller the loss to output power ratio and the higher the efficiency. On the contrary, the smaller the output power, the lower the efficiency.
Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;
Project scope.For example, in the 1970s, the radio programs applied by every family in the countryside had a ground wire, and they were often wet with tap water. Protective grounding is to bury the copper plate of metal electrical conductor in the soil layer, and then lead a point of it out of the road with transmission line, which completes the grounding protection. The grounding wire specifies the grounding wire resistance ≤ 4Ω. Grounding protection is a safeguard measure adopted to avoid safety accidents when using household appliances, office and other electrical equipment.
The technical specification of power consumption requires that the resistance of maintenance grounding wire shall be ≤ 4Ω, The resistor is generally more than 2000 & omega;, when the insulating layer is damaged the current is only 1 / 500 of the total current flow, so as to play a guarantee effect. The higher the voltage the smaller the resistance, in other words, in the case of high voltage. We can care about the power transformer plant and master a lot of professional knowledge.
How to reduce the failure of dry-type transformer?
In order to better carry out the experiment of power transformer oil, it is necessary to sample the power transformer oil. The sampling work should be carried out on a dry sunny day. The commonly used containers and sampling methods during sampling do immediate harm to whether the specific quality of the oil can be truly reflected. The oil sample for AC voltage withstand test shall not be less than 0.5kg, which are called test power transformers. They can be divided into inflatable, oil transformer, dry test and other test power transformers. They are the basic test equipment for communication AC compression test for many consumers such as power stations,BaikonilModel of 35kV dry type transformer, power supply bureaus and scientific research institutions. According to the specifications of the Bureau of quality supervision, It is used to carry out insulation compressive strength test under required current for various electrical products, electrical components and insulating raw materials.
Baikonil.Power transformer
The sampling container is a colorless glass bottle with a wide mouth ground glass plug with a volume of 0.5kg or 1kg. 2-3 bottles shall be collected at a time for analysis and experiment. Labels shall be attached during sampling. Pay attention to the name, source, sampling date, sampling person, weather conditions and other materials of the oil sample.
For the installation of lightning rod, it is very easy to damage the relay protection inside and outside of dry-type transformer by lightning. If it is a serious situation, power failure, damage to machinery and equipment, etc.
