Dry-type Three-phase Double-winding Distribution Transformer Description
The dry-type three-phase distribution transformer is a new - generation model of dry - type transformer, which serves as an energy - saving power transformer. It has a wide range of applications across various scenarios. These include power transmission and transformation systems, hotels and restaurants, high - rise buildings, commercial centers, stadiums, petrochemical plants, subways, railway stations, airports, and offshore drilling platforms. In particular, in places with limited installation space, where proximity to the load center is required, or where there are special fire - prevention demands, its advantages can be brought into full play.

Notes on Tap Changer Operation of the dry-type three-phase distribution transformer
Power - off and Safety Precautions:
Ensure that the 200 KVA 10 KV dry-type three-phase double-winding non-excitation tap-changing distribution transformer is powered off prior to tap changing. Implement appropriate safety measures to prevent any potential electrical hazards.
01
Simultaneous and Coordinated Switching:
All three phases must be switched simultaneously and to the same initial gear position. This synchronous operation is crucial for maintaining balanced electrical characteristics.
02
Contact Cleaning Procedure:
To mitigate the impact of oxidation films on contact performance, perform several back - and - forth switchings. Subsequently, set the tap to the desired gear. This process helps to clean the contacts and improve the dry-type three-phase double-winding distribution transformer's conductivity.
03
Post - switching Resistance Measurement:
After tap changing, measure the DC resistance of all three phases. This measurement serves as an important check to verify the proper connection and performance of the tap changer.
