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 project cost is different. Compared with the purchase price of capacity transformer, the purchase price of dry-type transformer is much higher than that of oil immersed transformer.

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; 0” 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.

Due to careless transportation of the transformer and the thin high-voltage conductor, we all know that it works with the help of oil. What if the oil immersed transformer is on fire? What countermeasures should we do?

Principle of step-up dry-type transformer: the step-up dry-type transformer is a component that correspondingly converts low communication AC voltage large current flow and small characteristic impedance into high communication AC voltage, small current and large characteristic impedance. When there is an AC circuit in the original coil, the communication AC magnetic flux will be caused in the transformer core (or magnetic core), causing the magnetic induction voltage in the primary coil (or current).

The oil in the machinery and equipment of the oil storage tank shall generally stand for more than 8h before sampling; it is not necessary to stand when sampling on the running power transformer.

Encyclopedic knowledge.After 24 hours of continuous trial operation with a certain load, the main body and accessories of the transformer are all normal, and the transformer will turn to all normal operation.

In the case of dry-type transformer operation,ChiguayanHigh voltage oil immersed transformer, there is more noise, and some even cause noise, which seriously endangers everyone's no problem rest time and work. At this time, the dry-type transformer needs sound insulation treatment. There are many processes and key methods to deal with the noise of the common dry-type transformer. How should the noise of the dry-type transformer be solved? Or with the dry-type transformer manufacturer's network editor to simply understand it.

Operation and maintenance management of oil immersed transformer

Total quality management.The insulating layer in the middle of the silicon steel plate is aging, the anchor bolt cover with the iron core is damaged, the iron core causes large vortex, resulting in heat, temperature rise,Chiguayan400 KVA price of box type transformer, and the aging of the insulating layer is accelerated. The core insulation compressive strength of power transformer must be measured on time and accurately. If it is found that the insulation compressive strength is less than the index value, please remove and replace the anchor bolt cover or carry out insulation for the copper core cable.

Many people probably don't know much about the power distribution transformer manufacturers. In fact, the transformer can be plugged in for trial operation after careful inspection before capital investment. During the trial operation period, you must pay attention to the following points. Whether there is abnormal sound, noise and vibration,ChiguayanMaintenance of oil immersed transformer, whether there is abnormal smell such as coke smell, and whether there is discoloration caused by partial overheating. Ventilation is good. In addition, 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.
