Relay protection inside the said fit and what is the difference between
Corresponding to the corresponding drawings to explain, each control loop are not the same!
Fit refers to the circuit breaker in the closing position, the specific performance of HWJ closed, closing lights.
KKJ is a relay of Nancy. Is the position after the combination, used to replace the previous KK handle after the position, the two series together to form the location does not correspond to the circuit to start the reclosing or accident total signal.
KKJ is a two-position relay, hand-held (including remote) start KKJ, KKJ contact closed, manual / remote control when opening KKJ re-starting the coil at the same time, KKJ contacts off. While the protection trip does not start the reset coil (ie, KKJ is still closed when the protection trip).
That is, when the circuit breaker in the closing position, KKJ contacts in the closed position, when the trip TWJ closed, and KKJ contacts in series together to start the reclosing or accident total signal can also be understood as the protection of the trip can To start reclosing, and hand points away from the points do not start reclosing.
In general, after the general deep Rui and NARI continue to use, such as reclosing, prepared from the vote after the need to judge after the location, after the show that the hand jump, do not start reclosing and prepared from the cast.
Joint refers to the state of the circuit breaker switch, after the operation should be the meaning of it
