Recently, the invention patent "A transformer test method" declared by TBEA Xinjiang Transformer Factory won the 16th "China Patent Award Excellence Award"
.
The award-winning patent belongs to the field of transformer technology and relates to a test method for transformers, in particular a railway traction transformer
.
The patent studied the test method of conventional transformer and found that the test power transformer must be 330kV voltage level, its investment cost is large, there is currently no test transformer for short-circuit test of this voltage level in China (the current test transformer is usually 220kV).
After research, the patent can complete the short-circuit peak current detection of ultra-high voltage transformer through the low-voltage level test transformer, achieve the test purpose, save the investment of test equipment, and have high practical value
.
This test method is particularly suitable for single-phase traction transformers
