To motor formation reduced-voltage starting, protection motor and current supply circuit safety.
(2) in the utility model during normal use, vacuum contactor KM auxiliary contact is because of overheat in reactance cabinet
Plastic deformation is blocked, and vacuum contactor KM normally opened contact and vacuum contactor KM the first normally-closed contact are a pair of contact, very
Empty contactor KM normally opened contact is changed into normally off, and vacuum contactor KM the first normally-closed contact is then changed into normally open,
When driving again, after the normal adhesives of primary cut-out QF of feeder cabinet, vacuum contactor KM is blocked because of auxiliary contact, causes to connect
Tentaculum actuating unit can not be operating normally, it is impossible to short circuit reactor, and reactor cabinet " starting timing transfinites " protection is because vacuum
Contactor KM the first normally closed point is not normal closure state, and protective condition is unsatisfactory for, it is impossible to it is normal start the second time after
Electrical equipment KT2.In feeder cabinet, the second time relay KT2 the first normal opened contact control circuit breaker Q F break-make, when second
Between relay KT2 the first normal opened contact when obtaining electric closure, circuit breaker Q F adhesives conversely, circuit breaker Q F is opened, therefore cause true
Empty contactor KM coils can not obtain electric, thus defencive function can not realize, and reactor cabinet " short circuit indicates loop " because of vacuum
Contactor KM normally opened contact closure, causes the glitch of loop " short circuit ", the utility model in vacuum contactor KM first
Second normally-closed contact of another pair contact in parallel on normally-closed contact, and two groups of auxiliary contact are separately mounted to vacuum contactor KM's
Both sides, normally-closed contact used in parallel, accordingly even when a pair of failures therein, the normally-closed contact of another pair remains to normally act as
With, reactor short circuit time-out loop, short circuit unsuccessfully trip also can normal work, excessive infringement will not be caused to reactor.
(3) time relay KT2 contacts of short circuit time-out are enabled in the utility model, its signal is returned into scheduling work
On control machine, by writing corresponding program, alarm indication is made on scheduling industrial computer, if under driving state, when short circuit is super
Constantly, display " alarm of short circuit time-out " on scheduling picture, dispatcher can notify to go inspection before electrician in time after alarm is found
Look into, timely cut off high pressure feeder cabinet, cut off equipment, then search and solve corresponding failure, reduce the long-term mistake of reactor
Heat burns possibility.
(4) short circuit indicator lamp is installed in the utility model, short circuit success so can be more intuitively checked whether.
Brief description of the drawings
Fig. 1 is a kind of schematic diagram of the control circuit of reactor cabinet of the utility model.
