The macro model of hybrid on-load tap-changer passive trigger
Abstract
Using thyristor as arc medium hybrid on-load tap-changer, completely solve the problem of switch produce arc, reduce the ablation of mechanical contact, improve the working environment of transformer oil, both mechanical switch and brake switch tube, the advantages of both resistance to overload, over current, over voltage capability, high reliability, long service life, maintenance workload small, suitable for frequent regulating occasions, reduce the operation cost transformer.
