Recently, China's first "334MVA/500kV single-phase self-coupling non-excitation voltage regulation power transformer short circuit test" was carried out
in Suzhou Electrical Research Institute.
The test passed the appraisal of the technical appraisal committee composed of 23 well-known domestic experts, and obtained the "new product and new technology appraisal certificate"
issued by the China Machinery Industry Federation and the Economic and Information Commission of Jiangsu Province.
The completion of the 500kV power transformer short-circuit withstand test marks that China has the technical ability
of 500kV large-scale power transformer short-circuit test.
In recent years, transformer products are developing in the direction of high voltage and large capacity, transformer short circuit accidents in network operation have been a problem that the power system tries to avoid but cannot be completely avoided, and the ability of transformers to resist short circuits has attracted the attention of the society
.
However, at present, it is still difficult to carry out the short circuit test of transformers with voltage levels above 220kV in China, which seriously affects the innovative development of transformer products in China and the safety of
power users.
Suzhou Electrical Research Institute Co.
, Ltd.
has spent two and a half years independently developing a 500kV transformer short-circuit withstand capacity test system, and has successfully completed it in China, and also successfully carried out a 500kV transformer short-circuit withstand capacity test
for customers for the first time.
It is of great significance to improve the domestic power transformer test capacity, help power users and manufacturing enterprises solve the difficulty of short circuit test of high-voltage, large-capacity power transformer, etc.
, and also provide a guarantee
for the improvement of product quality in China's power transmission and transformation field.

At the technical appraisal meeting, experts unanimously agreed that the test was successfully carried out for the first time in China, which has filled the domestic gap, and its technical level and test capacity have reached the international advanced level
.
Hu Delin, a researcher-level senior engineer and chairman of the board, said excitedly that the independent construction and first successful test of the test system are another new chapter
for the Electric Power Research Institute (300215, shares) to practice the "Chinese dream" and realize the "dream of a strong country".
