Description

Technical Field

[0002] Flexible low-frequency power transmission technology has technical and economic advantages in scenarios such as COSCO offshore wind power transmission, and its development prospects are very broad. At the same time, low-frequency flexible power transmission systems face new challenges such as equipment voltage fluctuations, system reactive power and harmonic characteristics optimization. The use of on-load tap changers in low-frequency power transmission transformers can effectively solve this problem. The function of the on-load tap changer is to ensure that the tap in the transformer winding, that is, the switching between the two gears, is achieved without interrupting the load current, thereby changing the number of turns of the winding. At present, most of the existing on-load tap changers use a spring-driven rack-and-pinion fast mechanism. Although this mechanism is stable and reliable, the switching time of the tap changer using this mechanism is generally around 80ms, so the switching time of the tap changer is relatively long and the working efficiency is low.
