Naturally, if the oil immersed transformer catches fire,BacaoTelephone number of dry-type transformer manufacturer, please don't panic. I firmly believe that the damage will be reduced to a lower level as long as the above methods are effectively rectified. Above is the general process and process that should be paid special attention to in the whole ignition process of the oil immersed transformer. When the oil immersed transformer catches fire, please be rational to make the oil immersed transformer safer and more efficient.
Bacao.At rated power, the ratio of output power to input power of transformer is called the efficiency of transformer,BacaoPartial discharge standard for dry type transformer, i.e. & ETA; Is the efficiency of the transformer; P1 is the input power and P2 is the output power.
Sound in case of phase failure
.The tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts, with good strength and stiffness, which is conducive to adjusting the data and has a unique and neat style.

The key reason for oil leakage is that there are defects in cast iron parts
It is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials porcelain, laminated glass and other materials very well,BacaoWhat is the price of 1000 KVA transformer, so as to achieve the pressure management of oil leakage.
In fact, apart from the application of the Finance Bureau, the industry has been trying to formulate and upgrade transformer commodities according to the specifications so as to promote the improvement of energy consumption level of transformer commodities.
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.

Common problems of tap changer of power transformer
Dry type transformer
Outdoor sampling shall be carried out in sunny days or dry weather with low environmental humidity. During sampling, it is necessary to resolutely prevent the invasion of dirt such as rain, snow, wind and sand.
Create brilliance.High voltage fuse of transformer breaks one phase;
The domestic transformer market is slow
If you want to check the activated carbon fiber for the hanging cover, first take out the low-voltage waterproof sleeve and the on load transformer power switch, then lower the bell cover anchor bolt of the large cover, slowly hang the galvanized steel wire rope with sufficient lifting net weight on the commonly used earrings, wear 4 round steel from top to bottom in the surrounding screw holes, and count the spacing and specifications for easy reinstallation. At the same time, the cable wind shall be added on all sides to ensure that the core international body will not be damaged during the whole lifting process. After lifting for 100mm, stop the lifting, stabilize the bell cover, and check the bearing capacity of the lifting core, center of gravity and Jack. After everything is normal, lift it again until the bell cover exceeds the relative height of the body, and rotate the crane to place the bell cover on the clean skid.
Bacao.Oil leakage at electric welding position
Due to careless transportation of the transformer and the thin high-voltage conductor, platinum thermistor (pt10) is placed beside the embedded hole on the top of the low-voltage solenoid coil to test the winding resistance temperature rise of the transformer, set up common problem alarm, overtemperature alarm and overtemperature tripping effect, and provide reliable overvoltage protection machinery and equipment for the dry test transformer, so as to test the safety performance of the transformer operation.
