Abstract
The utility model relates to a minisize simulation breaker, belonging to the electric system relay protection device detection technology field. The technical scheme comprises a DL control relay (3), a DL position relay (6), an opening relay (4), a closing relay (5) and a microcomputer relay protection device (9). The opening relay and the closing relay are used as a simulation coil to realize actions of opening and closing. The DL position relay is used for controlling position change of a breaker auxiliary contact DL to realize actuation and separation of the DL control relay. The actuation and separation of the DL position relay control actions of opening relay and closing relay which are used as the simulation coil, and changes the on-off state of the breaker auxiliary contact DL in the process of actions, so that a interlock control loop is formed. The minisize simulation breaker can effectively reduce times of switching transmission when a protective test is running, reduce damages caused by transmission and reduce workload requiring manual switching on and off.
