Wiring mode of dry-type transformer:Analysis of common faults of oil immersed transformer:Castukovich,Transformer inspection nose sniffing methodFor the leakage that has already occurred, which can not be ignored. For the position with serious leakage, shovel or sharp punch can be selected. The leakage point can be riveted with special tools for metal materials. After manipulating the leakage, the treatment surface shall be cleaned and tidy. Polymer composite materials are mostly selected for dry consolidation. After dry consolidation, the goal of long-term treatment of leakage can be achieved.Wesselsbron,The power transformer is composed of two or more electromagnetic coils wound around the same transformer core. The winding resistance is connected according to the alternating electromagnetic field and works according to the basic principle of magnetic effect of current. The installation position of power transformer shall be considered to be conducive to operation, maintenance and transportation, and a reliable area shall be selected at the same time. The rated capacity of the transformer must be effectively used when applying the transformer.The method and whole process of taking oil sample of power transformer are as follows:Oil leakage of bolt or pipe external thread

How much is the power transformerThere is a magnetic induction line crossing in the transformer core, which will cause induced electromotive force on the plan with the magnetic induction line. Because this electric flow creates a closed loop to generate an electric field and forms a vortex, it is called vortex. The existence of vortex makes the transformer core hot and consumes kinetic energy. This kind of loss is called vortex loss.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.Latest consultationAvoid the load operation of power transformer: if the load operation is long-term, short circuit fault between boxes slow aging of insulation,CastukovichRecovery room transformer, two-color short circuit fault or short circuit to ground fault and dissolution of oil.The noise of dry-type transformer is mainly the vibration noise in operation. This vibration noise is caused by multiple positions, including the vibration of magnetic induction electromagnetic coil. All pay great attention to the solution of vibration when carrying out noise control.& ldquo; of wiring transformer; Enter & rdquo; And & ldquo; Output & rdquo; Use a megger to test the grounding resistance between the terminal and the ground wire. When accurately measured by V megger, the resistance value exceeds m ohm bus.

The 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.query,The raw materials of Fushi blue can be used for bonding,Castukovich4000kva dry type transformer, so that the overall oil leakage of the connector can be greatly controlled; If the actual operation is convenient, the metal shell can also be bonded at the same time to achieve the purpose of leakage treatment.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.Solenoid insulation deteriorationCastukovich,Fault judgment of power transformerWhat is the reason for the shutdown of power transformer?(IV) the transformer on the column shall be stable and firm, and the waist rail shall be & phi; mm galvanized wire shall be wound over turns in an even number. The iron wire shall not have a connector and shall be tightened after winding. The distance between the waist rail and the energized part shall not be less than .m.
