On November 27, 2022, the first domestic converter transformer tap-changer equipped in ±500kV converter transformer was successfully put into operation at Xiluodu DC project from the west converter station. The on-load tap-changer 'neck' problem of the converter transformer was successfully solved.Huaming SHZVⅡ-1300/72.5D-14271W current transformer on-load tap-changer adopts Chinese vacuum interrupter for the first time, with an electrical life of 300,000 times and a mechanical life of 1.5 million times. At the same time, it is also the first time to adopt the Chinese on-load tap-changer online monitoring system with oil chromatography monitoring and other functions developed by Huaming, which protects the operation of the product.As the core component of the power transformer...

In the past 2022, the second UHV product of Huaming was officially put into operation. The tap-changer, equipped in a converter transformer, was used in the '±500kV Xiluodu DC Transmission Project'.Not known to the public, 'tap-changer' and 'bushing' are the last two components to be localized in the field of EHV, which is also the most difficult. UHV was created by China, but for a long time UHV on-load tap-changer has been monopolized by international enterprises, and China did not master its core technology.In the field of tap-changer, Huaming has assumed the role of breaking the 'neck' of key foreign technology, said Xiao Yi, CEO of Huaming, 'This is the embodiment of national power, Huaming is proud to be a supporting role.'UHV, like high-s...
