Abstract
A terminal I thereof is respectively connected with transition switches, and a terminal II is respectively connected with transition switches; the other terminals of the transition switches are jointly connected and are connected with the terminal through a saturable reactor and a thyristor switch; the other terminals of the transition switches are jointly connected and are connected with the terminal through a linear reactor, a saturable reactor and an overvoltage triggering thyristor circuit; an odd-numbered side main contact is respectively connected with the terminal I and a common terminal, and an even-numbered side main contact is respectively connected with the terminal II and the common terminal; the terminals of non-common terminals of a main path and a transition path are further connected with a bidirectional voltage stabilizing circuit.
