The invention discloses a
simulation circuit breaker test device for maintenance, and relates to the technical field of
relay protection debugging and maintenance. In a
relay protection debugging or maintenance process, a transmission
circuit breaker needs to be operated or protected for many times. The
simulation circuit breaker control system comprises a
simulation circuit breaker control module, an input module, an output module, a communication module, an
aviation plug interface, a battery module and a
mobile control terminal, the simulation circuit breaker control module adopts a double-coil latching
relay to simulate an opening and closing coil of a three-phase circuit breaker, and the simulation circuit breaker control module comprises two groups of control loops; a high-
voltage circuit breaker can be replaced for
verification of a protection function, a
secondary circuit and the like, and two groups of control circuits lead out wires through
aviation plug interfaces. The device can replace a high-
voltage circuit breaker to carry out repeated protection function and
secondary loop verification in a maintenance process, so that frequent operation of the high-
voltage circuit breaker in an actual maintenance process is avoided, the action frequency of the high-voltage circuit breaker is remarkably reduced, and the maintenance quality and reliability of equipment are improved.
