Sound，ZardabuBox type transformer 400kV，Zardabu315 KVA oil immersed transformer， causing short circuit obstruction. If not handled properly， it will cause great damage.
What is the important role of power transformer
ZardabuThe cycle time of power-off cleaning and inspection shall be determined according to the surrounding environment and load conditions， generally from half a year to once a year;
The noise of dry-type transformer is mainly the vibration noise in operation. This vibration noise is caused by multiple positions， customers must master the method of wiring. If there are problems in wiring， it is easy to cause common faults in application. So， what is the wiring mode of dry-type transformer?
There are also many problems to pay attention to in the preventive measures and process of dry-type transformer damping. What are the key effects and functions of dry-type transformer damping and the corresponding preventive measures? Let"s master and consult in detail with the small editor of the dry-type transformer manufacturer.
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.
Dry type transformer oscillation is solved by applying vibration damping platform to dry-type transformer and carrying out low-frequency vibration reduction management， which can control the oscillation below .%， and then reduce the building structure noise transmitted by dry-type transformer oscillation.
The cycle time of power-off cleaning and inspection shall be determined according to the surrounding environment and load conditions， generally from half a year to once a year;
A specific part of dry-type transformer is the hanging core of dry-type transformer. The hanging core of dry-type transformer is a vital component. How to carry out the hanging core?
Customer firstThe main reason is that the welding quality of electric welding is poor， there are empty welding， open welding， needle holes， and the potential safety hazards are exposed after operation. In addition， the electromagnetic induction vibration will crack the electric welding and lead to leakage.
What about oil immersed transformer fire?
Deterioration damage of transformer core insulation
When oil samples are used the safety and fire safety technical specifications on the spot shall be strictly implemented.
Honesty and mutual benefitThe tap changer of power transformer shall also have strong insulation. kV off load tap changer is generally insulated from the ground by the produced insulating paper pipe factory.
Many people probably don"t know much about the power distribution transformer manufacturers. In fact， you must pay attention to the following points. Whether there is abnormal sound the transformer can be plugged in for trial operation after careful inspection before capital investment. During the trial operation period， noise and vibration， whether there is abnormal smell such as coke smell， and whether there is discoloration caused by partial overheating. Ventilation is good. In addition，Zardabu80 KVA oil immersed transformer， we should also pay attention to the following aspects.
& 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.
Zardabu(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.
() the installation position of secondary commercial insurance of transformer on column and ground shall meet the following requirements: if there is an disconnector on the secondary side， it shall be installed between the disconnector and low-voltage composite insulator， or the circuit breaker shall be selected as the disconnector; If there is no disconnector on the secondary side， it shall be installed on both sides of the low-voltage composite insulator， and the insulated cable jumper shall be connected to the insulated cable on both sides of the circuit breaker.
The insulation distance between the winding and the iron yoke of power transformer is much larger than that between the windings， because the electric field between the winding and the iron yoke is far away and not as symmetrical as that between the windings. In the electric field in the middle of the winding， most of the cables are in phase with the insulating cylinder (plate) in the middle of the winding， that is， the disconnection component of the electric field is small.
