BaktapurScb13 Protective measures for damping of dry-type transformer
Deterioration damage of transformer core insulation
Manbang.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, we will describe how to select dry-type transformer according to the load characteristics and application environment of dry-type transformer.
How to reduce the failure of dry-type transformer?
.Solenoid insulation deterioration
Deterioration damage of transformer core insulation
When checking the hook core, the insulation of the electromagnetic coil and the porcelain sleeve is usually accidentally damaged. After the shell of the pottery is broken, if you work again, turn on the photo flash when it's light, and it's short when it's heavy. Therefore, please pay attention during maintenance. It is not necessary to destroy the insulation. After maintenance,ManbangOil immersed self cooling transformer, parts, insulation, etc. and deliver them after they are determined to be complete and reliable.
After the oil is drained, all anchor bolts of the automobile oil tank at the upper end of the detachable oil cover shall be tied with the lifting jack, and the lifting point shall be on the common earrings or bolts. If necessary, the human resources traction belt shall be used as a guide.
After the power transformer has been used for a long time, common faults of iron core will occur. Don't worry. Contact the transformer manufacturer, and the manufacturer will assign professional technicians for inspection. The main reasons are as follows:
In the case of using dry-type transformer, 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?
Welcome calls .Falling foreign matters and piercing
The representative mode of connection group of dry-type transformer is: English capital letters indicate the wiring on the primary side (or primary side),ManbangDry type transformer industry ranking, and English letters indicate the wiring on the secondary side (or secondary side). Y (or y) is star wiring, and D (or D) is triangular wiring.
Before no-load impulse closing,ManbangPrice of 500 KVA box type transformer, the transformer shall be placed for 24h, and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.
Protective measures for damping of dry-type transformer
Variable cost.The raw materials of Fushi blue can be used for bonding, 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.
Once the insulation material of electrical equipment is overheated, the surrounding gas will cause a kind of odor. This kind of odor can be sniffed out by normal patrol staff. When you smell such odor during normal inspection, you should carefully inspect the equipment and parts until you find out the cause.
Power transformer factory
Manbang.After no-load test run is normal for 24h, it can be transferred to on-load operation and the load shall be gradually increased from 25%, and we can't neglect it in daily application. The common problems of power transformer conductor, power transformer winding and power transformer tapping power switch are analyzed below:
Loose core screw
