Avoid the load operation of power transformer: if the load operation is long-term， it will lead to the scalding of solenoid coil， slow aging of insulation， two-color short circuit fault or short circuit to ground fault and dissolution of oil.
After tightening the loose bolts， seal the flange，CowenMaintenance of oil immersed transformer， 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.
CowenProtection mode for type selection of dry-type test transformer
Therefore， 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.
DICOWhen 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，
Therefore， 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， lock the fault point 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.

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.
The person in charge of a transformer manufacturer said that because of the hazards of raw materials and other factors， and the price factor is also a key factor endangering the popularization and marketing of energy-saving transformers. Although there are energy-saving and convenient subsidy projects to help energy-saving transformers， the market has not yet fully operated.
Oil leakage of bolt or pipe external thread
StatisticsGenerally speaking， the ignition emergency treatment method of oil immersed transformer is mainly to disconnect the oil immersed transformer， disconnect the switching power supply on each side， quickly invest the reserved oil immersed transformer and start the power supply system from scratch. Stop the operation of refrigeration equipment. Key oil immersed transformer ignition. When L-type oil immersed transformer and high voltage station oil immersed transformer are ignited， the generator set must be disassembled first.
Dry type transformer company
The sampling container is a colorless glass bottle with a wide mouth ground glass plug with a volume of .kg or kg. - bottles shall be collected at a time for analysis and experiment. Labels shall be attached during sampling. Pay attention to the name，CowenPrice of 5000KVA transformer， source， sampling date， sampling person， weather conditions and other materials of the oil sample.
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.
Quality assuranceThe first step of the whole wave process calculation is to calculate the basic parameters of the Internet such as inductance， capacitance and resistor. The accuracy of those basic parameters does great harm to the calculation results of the whole wave process. For the inductance calculation， the good model is the solid model of infinite transformer core column， but there are many calculation methods.
The common dry-type transformer is an important electrical equipment， and the voltage is constantly regulated. However， because of certain necessity， the dry-type transformer will also boost voltage， and the whole process of boosting voltage is very complex， and there are many principles.
Connection group structure of dry-type transformer
CowenPower transformer is one of the key equipment in power station and substation. The function of power transformer is in all aspects. It can not only raise the voltage and send electromagnetic energy to the power consumption area， but also reduce the voltage to each application voltage so as to meet the needs of power consumption. In short， voltage transformation and blood pressure reduction must be carried out by the transformer.
Protective measures for damping of dry-type transformer
(I) the distance between the external contour of kV and below dry-type transformer and the surrounding guardrail or courtyard wall shall take into account the convenience of transportation and repair of dry-type transformer，CowenOil immersed regulator， and the distance shall not be less than m; At the angle with actual operation， a spacing of more than m shall be reserved; If metal fence is selected， the metal fence shall be grounded and a warning sign shall be hung at a prominent position.
