Abstract
Traditional transformer on-load tap-changers produce an arc when switching the winding tap action, and the arcing exotherm can affect the insulation performance of the contacts and accelerate the deterioration of the transformer oil, which ultimately leads to a significant reduction in the transformer’s voltage regulation performance and affects the safe operation of the transformer. This paper analyzes the thyristor gate characteristic curve in detail to find out the region of reliable driving thyristor; on this basis, combined with the design of ideal driving signal index, it puts forward the method of calculating and selecting the parameters of thyristor driving circuit based on the gate characteristic curve; finally, it constructs the thyristor-type electronic diverter switch to carry out the experimental validation, and it provides a reference scheme for designing and selecting the key components of the thyristor driving circuit in the power electronic on-load tap-changer.
