You must be unfamiliar with the term dry-type Transformer size, don’t you know what it means? Now we come to know more about it. The cooling methods of dry Transformers are divided into natural air cooling (AN) and forced air cooling (AF). In the case of natural air cooling, the Transformer can run continuously under rated power for a long time.
What should be considered before Dry Type Transformer is officially used?
How do I check the Transformer to see if it can function normally?
What is the future development trend of dry Transformers?
Check the input and output lines of the dry Transformer to make sure they are correct.
1. Switch on first in the blank and observe and test whether the input and output voltage meets the requirements. Watch the machine at the same time
Whether inside, unusual sounds, sparks, strange odours, etc. Please disconnect the input voltage immediately.
2. After the dry Transformer is finished and normal, the load can be connected.
9352Whether unusual sounds and vibrations occur.
Whether local overheating, damage corrosion and other discolouration occur due to creep marks and cocooning on the insulating surface.
Whether the air cooling of the Transformer functions normally.
There should be no overheating of the high and low voltage connections. There shall be no leakage or creep currents on the cable head.
The temperature increase of the windings should be based on the insulating material quality used by the Transformer and the temperature increase monitored should not exceed the specified value.
The carrying porcelain bottle should be free of cracks and exit traces.
Check if the wrapping pressure piece is loose.
Internal ventilation and iron core air ducts should be free of dust and dirt, and iron cores should be free of rust or corrosion.
With the popularization and application of dry Transformers, its production technology has also achieved considerable development. It is to be expected that future dry Transformers will be further developed in the following aspects:
Energy-saving and low-noise: With the introduction of new low-consumption silicon steel sheets, film winding structures, graduated iron core connections, environmental protection requirements, in-depth noise research and the introduction of new materials, new processes and new technologies B. Computer optimization design, will make future dry Transformers more energy efficient and quieter.
High reliability: Improving product quality and reliability will be the tireless striving of people.
Certification of environmental protection properties: Based on the European standard HD464, conduct the research and certification of weather resistance (C0, C1, C2), environmental resistance (E0, E1, E2) and fire resistance (F0, F1, F2). from dry Transformers according to the European standard HD464.
The above is the relevant information about dry type Transformers. At present, the use of dry type Transformers has become more and more widespread. If you get more information, please contact Zhejiang Zhegui Electric Co., Ltd.
