Late starting-up later time, closing circuit, vacuum contactor control loop parallel connection is both connected to the two ends of power supply；
Delay start loop is the coil series connection of circuit breaker Q F, auxiliary reclay KA；
Coil series connection of the closing circuit for the normal opened contact and relay 1ZJ of auxiliary reclay KA；
Vacuum contactor control loop is that the normal opened contact of the relay 1ZJ is connected with the coil of vacuum contactor KM；
The reactor cabinet is connected in parallel on the two ends of power supply.
Also include very first time relay KT1, the coils from parallel connection of coils of the very first time relay KT1 is in auxiliary reclay KA
Coil two ends, the normal opened contact of the very first time relay KT1 is arranged on closing circuit, and with auxiliary reclay KA
Normal opened contact series connection.
Also including stop button SB, conversion knob SB1, start button SB2, the conversion knob include automatic position switch and
Manual position switch；
The stop button SB is connected on closing circuit after being connected with the two ends of automatic position switch again；
The manual position switch is connected with start button SB2, and the circuit in parallel of series connection is in the normal of very first time relay KT1
The two ends for opening contact and the circuit after the connection of automatic position switch form control locked loop.
The two ends of the manual position switch and start button SB2 series circuit are also parallel with the normal opened contact of relay 1ZJ
Form self-holding circuit.
Also include that starting timing transfinites loop, startup timing loop of transfiniting includes that vacuum contactor KM's is first normally closed
The normal opened contact of contact, auxiliary reclay KA, the second time relay KT2；The startup timing loop of transfiniting is connected in parallel on power supply
Two ends；First normally closed contact of the vacuum contactor KM, the normal opened contact of auxiliary reclay KA, second time relay

It is an advantage of the current invention that：
(1) chopper QF adhesives in the present invention, high-tension electricity reaches reactor cabinet upper port by cable, now due to reactance
The also no adhesives of vacuum contactor KM in device cabinet, so high-tension electricity is added on reactor, when open circuit in delay start loop
When device QF is closed, timing circuit starts, auxiliary reclay KA, time relay KT1 all adhesives, and corresponding reactor cabinet " closes a floodgate
Time relay KT1's in loop " and the auxiliary reclay KA closings of contact, if now controlling stop button SB closure, turning
Knob SB1 is changed at automatic position switch and closure, " closing circuit " condition of reactor cabinet meets, relay 1ZJ adhesives, relay
Device 1ZJ normally opened contacts are closed, i.e. vacuum contactor control loop conducting, i.e., the vacuum contactor KM coil adhesives in the loop,
After vacuum contactor KM adhesives, as vacuum contactor and reactor are in parallel, its resistance is far smaller than the resistance of reactor,
Electric current is walked from low-resistance catalyst branch road in shunt circuit, this completes " short circuit " work of reactor, to motor
Form reduced-voltage starting, protection motor and current supply circuit safety.
(2) in the present invention during normal use, in reactance cabinet, the auxiliary contact of vacuum contactor KM is because crossing thermoplastic materialss
Deformation is blocked, and the first normally-closed contact of the normally opened contact and vacuum contactor KM of vacuum contactor KM is a pair of contact, and vacuum connects
The normally opened contact of tentaculum KM is changed into normally off, and first normally-closed contact of vacuum contactor KM is then changed into normally open, when again
During secondary driving, after the normal adhesives of primary cut-out QF of feeder cabinet, vacuum contactor KM is blocked because of auxiliary contact, causes catalyst
Actuating unit can not be operating normally, it is impossible to short circuit reactor, and reactor cabinet " starting timing transfinites " protection is because vacuum contact
The first normally closed point of device KM is not normal closure state, and protective condition is unsatisfactory for, it is impossible to normal to start second time relay
KT2.In feeder cabinet, first normal opened contact of the second time relay KT2 controls the break-make of circuit breaker Q F, when the second time after
When first normal opened contact of electrical equipment KT2 obtains electric closure, the adhesive of circuit breaker Q F conversely, circuit breaker Q F is opened, therefore causes vacuum to connect
Tentaculum KM coils can not obtain electric, thus defencive function can not be realized, and reactor cabinet " short circuit instruction loop " because of vacuum contact
The normally opened contact closure of device KM, causes the glitch of loop " short circuit ", first normally-closed contact of the present invention in vacuum contactor KM
Second normally-closed contact of upper a pair of contact in parallel another, and two groups of auxiliary contact are separately mounted to the both sides of vacuum contactor KM, and
Connection uses normally-closed contact, accordingly even when a pair of failures therein, the normally-closed contact of another pair remains to proper function, 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 present invention, its signal is returned to into scheduling industrial computer
On, by writing corresponding program, alarm indicator is made on scheduling industrial computer, if under driving state, when short circuit time-out,
" short circuit time-out is reported to the police " is shown on scheduling picture, dispatcher after finding to report to the police can go to check before notifying electrician in time, in time
Cut off high pressure feeder cabinet, cut off equipment, then look up the corresponding failure of solution, reducing that reactor long-term overheat burns can
Energy.
(4) short circuit display lamp is installed in the present invention, so can more intuitively checks whether short circuit success.
