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.Connection group structure of dry-type transformerBytca,Visual inspection method for transformer inspectionThen clamp the branch pipe with your thumb, clearly put forward the glass test tube, rotate and release the oil in the tube to clean the sampling tube, carry out it twice, and then draw the oil sample.Kosice,Dry type transformer manufacturerFalling foreign matters and piercingThe bearing capacity of each load is different. Generally,BytcaPrice list of 315 KVA box type transformer, dry-type transformer should operate under rated capacity, while oil transformer has better load working capacity.
Power transformer plantPower transformer is indispensable for power stations and substations, but we must pay attention to many problems in the whole process of applying power 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 .kg, and the oil sample for simplified experiment shall not be less than kg.Professional is king,Oil leakage at electric welding positionOutdoor sampling shall be carried out in sunny days or dry weather with low environmental humidity. During sampling, it is necessary to resolutely prevent the invasion of dirt such as rain,BytcaAbout transformer, snow, wind and sand.Then clamp the branch pipe with your thumb, clearly put forward the glass test tube, rotate and release the oil in the tube to clean the sampling tube, carry out it twice, and then draw the oil sample.
Avoid aging and damage of power transformer iron core insulation: aging of iron core insulation or damage of waterproof sleeve holding anchor bolt will cause large vortex of iron core, and long-term scalding of iron core will lead to insulation aging.plan,BytcaTransformer distribution room,Method and process of taking oil sample of power transformerThe dry-type transformer used for power plant voltage transformation is different from the oil transformer. It is strictly prohibited to lead the way at the bottom voltage side to prevent the insulation layer of the dry-type transformer from penetrating due to overvoltage caused by overvoltage at the power grid side or lightning stroke on the line.The time difference between different steps of three-phase power switch of switching power supply shall be less than ms, the closing shall be maintained by high-voltage arrester, and the neutral line of transformer shall be reliably grounded (it shall be grounded immediately).Bytca, in the operation prevention and regulation of relay protection dry-type transformer it is necessary to find the short-circuit fault point according to the fault situation, and analyze the short-circuit fault types of relay protection dry-type transformer. At the same time, if all fields are clear, disconnect the switching power supply at the fault point the maintenance work of employees will be carried out smoothly, and the harm will not expand to a greater extent.The key reason for oil leakage is that there are defects in cast iron partsWhat is the wavelength of oil immersed transformer?
