The first large-capacity transformer in China passed the burst short circuit test

The DFP-240000/400TH power transformer independently researched and developed by Shandong Electric Power Equipment Co., Ltd. passed the sudden short-circuit test in KEMA, an authoritative international quality certification organization in the Netherlands. This is the first high-capacity transformer in China to pass this test. The withstand short-circuit capability test is a special test of the transformer, which stipulates that the power transformer should be free from damage under the action of overcurrent caused by an external short circuit, and is a comprehensive assessment of the structural design and manufacturing process of the transformer. At present, the 400 kV class transformer with the largest single-column capacity through KAMA's sudden short-circuit test has filled the gap in domestic power transmission and transformation technology and laid the foundation for Shandong Power Equipment Co., Ltd. to further explore the international market.

Founded in 1927, KEMA's KEMA electrician equipment tests all of the world's oldest high-voltage test chambers and the largest installed capacity of high-current test chambers. It is a global leader in the field of high-voltage equipment testing, and also a high-voltage test and certification. The world-famous companies enjoy a high reputation internationally. It is the highest honor that the world-renowned power transmission and transformation equipment manufacturers obtain the test certification of KEMA Company. In 2011, the pass rate of transformer products that the company conducted the short-circuit test was only 30%.

The Shandong Electric Power Equipment Co., Ltd. transformers passed the test, and the impedance value change was less than 0.5%. The indicators were excellent and the performance was stable. It was the first single-phase 240MVA that passed the STL KEMA laboratory short-circuit test. /400kV power transformer, capacity close to KEMA's largest test capability, is the largest single-cylinder 400kV transformer product through KEMA's sudden short-circuit test in China, filling the gap in domestic power transmission and transformation technology field for Shandong Power Equipment Co., Ltd. Further lay the foundation for the development of the international market.
