Abstract
A high voltage self-blowing circuit breaker with closing resistors is equipped with an auxiliary contact inserted in the trip control circuit of an electrical circuit breaker. The auxiliary contact is actuated by the mechanical control rod of the circuit breaker, in such a way as to prevent any operator closing error. A high-speed mechanism is inserted in the link system connecting the control rod and the auxiliary contact, with a dead travel mechanism to delay closing of the auxiliary contact when a closing operation takes place and to prevent a tripping order, liable to cause a flashover on the inserter contacts and damage to the circuit breaker, from being transmitted too early.
