Turn off the gate valve (butterfly valve) of the left and right tablet computers of the heat pipe radiator to isolate the oil in the heat pipe radiator from the oil in the tank， so as to reduce the working pressure and leakage. After the leakage location is determined， appropriate surface treatment shall be carried out， and then Fushi blue raw materials shall be selected for sealing treatment.
Insulation and heat removal are different. Dry type transformers are generally insulated with epoxy resin， cooled by natural air and large capacity by centrifugal fan. Oil immersed transformers are insulated by insulating oil，AljomHow does the transformer send electricity， insulated by insulating oil in the circulating system inside the transformer， and heat is discharged on the radiator (radiator) of the circulating system inside the transformer.
AljomWhen the operating oil is mixed with different types of new oil or used for oil in addition to the accurate measurement of the cold filter point of the mixed oil， it is also necessary to carry out high and low temperature test and sludge test and observe the sludge accumulation. The accumulation cannot be accessed. The results of the operation of the mixing template are not that the original oil is very poor， so it can be managed and used in a mixed manner.
Protective measures for damping of dry-type transformer
Fanlang ChazhanThe zero line is mainly used in the working circuit. The voltage caused by the zero line is equivalent to the line resistance multiplied by the current of the working circuit. Because of the distance， the voltage caused by the zero line can not be ignored. As a countermeasure to maintain life safety， it is more and more unreliable. Ground wire (PE): it is not used as a working circuit， but only as a maintenance line. Use the affirmation of the earth & ldquo; ” Voltage. When the machine and equipment casing is electrified， the current will be quickly grounded. Even if there is a lead for the PE line， it will be grounded from the surrounding grounding body.
Manufacturing process and steps of dry-type transformer
Wiring mode of dry-type transformer:
Use fiber materials to seal the bolts to achieve the goal of controlling leakage. The other is to screw out the bolt (nut)， wipe the Fushi blue film remover on the surface， and then tighten it after wiping the raw materials on the surface. After drying， 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.
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，Aljom1600KVA box transformer price， the dispersion spacing and adverse effects are very large.
assetsWhen the whole process of winding wave of oil immersed transformer is calculated by using the marking method， the winding of oil immersed transformer is generally divided into multiple modules， and each module is replaced by an equivalent circuit， and its power circuit includes an inductance and vertical capacitance， a capacitance to ground or capacitance between windings， They also have mutual inductors between the inductors of each module， and collect the chain Internet as the equivalent power circuit of oil immersed transformer. The precision of the conclusion can completely meet the needs of practical projects.
Wiring mode of dry-type transformer:
When leaving the factory， the production and processing are not smooth and the sealing is poor. The common fault of oil leakage will be caused after the oil transformer is sealed for a period of time.
The noise of dry-type transformer comes from
Convenient and efficientCauses of fire in power transformer
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， we have already mastered the structure and characteristics of dry-type transformer. In this part， the pose period of overcurrent protection shall be set to zero， open welding there are empty 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.
