Automatic transformer demagnetization machine is a special equipment for eliminating residual magnetism after dc resistance test of large power transformer. It plays a very important role in protecting the transformer from the impact of inrush current, safe operation and prolonging transformer life.
Two, the main characteristics
1, suitable for 35KV and above large power transformers before operation to eliminate remanence.
2, the demagnetization speed is fast, three-phase transformer demagnetization once or twice.
3, the instrument is equipped with automatic test and manual test.
4, the maximum degaussing current is 10A, with automatic, 10A, 5A, 1A, 500mA, 200mA a total of six levels of degaussing current, to meet the different test needs of users.
Use 220V AC power supply onsite.
Percentage of progress displayed during demagnetization.
The instrument is simple to operate, small in size, light in weight and easy to carry.
