The utility model provides a pair of direct current contactor with self -checking function, the micro -gap switch that adoption and movable contact assembly triggered in step directly monitors direct current contactor's operating condition, has improved direct current contactor's self reliability, makes the external circuit design simpler.
Description
Technical field
This utility model relates to D.C. contactor technical field, particularly relates to a kind of D.C. contactor with self-checking function.
Background technology
The sound contact of D.C. contactor is all enclosed in enclosure interior, when D.C. contactor works, cannot determine after powering on, whether D.C. contactor enters duty intuitively, whether sound contact closes, it is generally required to just can determine that D.C. contactor whether normal operation, detection complicated operation by outside device measuring related output signal.
Utility model content
Technical problem to be solved in the utility model is: in order to overcome the deficiency that can not directly determine duty in prior art on D.C. contactor after electric current, and this utility model provides a kind of D.C. contactor with self-checking function.
The technical scheme that this utility model solves its technical problem to be taken is: a kind of D.C. contactor with self-checking function, including housing, stationary contact assembly, movable contact assembly and panel, also include microswitch, described microswitch is fixing with described stationary contact assembly to be connected, and the wiring pin of described microswitch and described panel connection, described microswitch is provided with movable contact spring, and described movable contact spring is connected with and the cantilever of described movable contact component synchronization motion.
Whether microswitch closes for the movable contact detecting D.C. contactor, the duty of monitoring D.C. contactor, when the energising of movable contact assembly moves upward, push rod drives cantilever to move upward simultaneously, and cantilever promotes the movable contact spring of microswitch to move upward Guan Bi, when panel receives the signal that microswitch closes, the D.C. contactor sound closing of contact is described, normal operation, otherwise, control system does not receive the signal instruction D.C. contactor fault of microswitch Guan Bi；When after movable contact assembly power-off, sound contact separation, push rod drives cantilever to move downward, cantilever is applied on microswitch movable contact spring to upward pressure reduction, movable contact spring flicks under the effect of its own resilient, makes microswitch disconnect, and panel illustrates that D.C. contactor normally disconnects after receiving cut-off signal, otherwise, control system does not receive the signal instruction D.C. contactor fault that microswitch disconnects.
Further, described movable contact assembly includes push rod, and described cantilever one end is fixing with described push rod to be connected, and the described cantilever other end and described movable contact spring align up and down.
Concrete, described cantilever is right angled triangle or right-angled trapezium along the section of described push rod axis direction.
The beneficial effects of the utility model are: a kind of D.C. contactor with self-checking function that this utility model provides, the microswitch triggered with movable contact component synchronization is adopted directly to monitor the duty of D.C. contactor, improve the reliability of D.C. contactor self, make external circuit design simpler.
