KMZ1 forms interlock circuit, and the first band-type brake contactor KMB and the second band-type brake contactor KMB1 form interlock circuit.Work as master control system
When be failure to actuate, the second band-type brake contactor KMB1, the second band-type brake of the second rescue system 6 are strong for 5 movements and the second rescue system 6
The normally-closed contact for swashing contactor KMZ1 and the second main contactor KMY1 is closure, and KMZ in the second rescue system 6,
The normally-closed contact of KMB, KMY are to disconnect, and prevent the second rescue mainboard from accidentally outputing signal to KMZ1, KMB1, KMY1, are formed mutual
Lock.Conversely, when master control system 5 be failure to actuate and the second rescue system 6 act when, the first main contactor KMY, the first band-type brake are strong
The normally-closed contact for swashing contactor KMZ and the first band-type brake contactor KMB is closed, and the KMZ1 of main system, KMB1, KMY1 are disconnected
It opens, when preventing the second rescue from acting, main system malfunction guarantees that traction machine and band-type brake coil are only accepted one group of system and provided
Signal.When preventing simultaneously operation, overtension burns band-type brake coil and traction machine.It plays a protective role.Specifically, such as Fig. 2
With shown in Fig. 3, when the first band-type brake contactor KMB of master control system 5 output Y0 closure when, the line of the first band-type brake contactor KMB
Circle is powered, and the normally-closed contact of the first band-type brake contactor KMB disconnects, and the coil of the KMB1 of the second rescue system 6 will not be powered, avoid
The Y0 of second band-type brake contactor of the second rescue system 6 is malfunctioned.When the first band-type brake of master control system 5 swashs by force contactor KMZ's
When exporting Y1 closure, the coil that the first band-type brake swashs by force contactor KMZ is powered, and the first band-type brake swashs by force the normally-closed contact of contactor KMZ
It disconnects, the coil of the KMZ1 of the second rescue system 6 will not be powered, and the second band-type brake of the second rescue system 6 is avoided to swash contactor by force
The Y0 of KMZ1 is malfunctioned.When the output Y2 of the first main contactor KMY of master control system 5 closure, the line of the first main contactor KMY
Circle is powered, and the normally-closed contact of the first main contactor KMY disconnects, and the coil of the KMY1 of the second rescue system 6 will not be powered, and avoids the
The Y2 of second main contactor of two rescue systems 6 is malfunctioned.Similarly, when the second rescue system 6 is rescued, the second rescue system
6 Y0, Y1, Y2 closure, then the second band-type brake contactor KMB1 of the second rescue system 6, the second band-type brake by force swash contactor KMZ1 with
And second main contactor KMY1 coil be powered, then the second band-type brake contactor KMB1, the second band-type brake of the second rescue system 6 swash by force
The normally-closed contact of contactor KMZ1 and the second main contactor KMY1 disconnect, and prevent Y0, Y1, Y2 of master control system 5 from malfunctioning.
It can effectively prevent forming malfunction between master control system 5 and the second rescue system 6 between the interlock circuit of this form, have
Effect guarantees the accuracy of rescue and rescue system.It can guarantee that traction machine and band-type brake coil are only accepted one group of system and provided simultaneously
Signal.In addition, overtension burns band-type brake coil and traction machine, and then plays a protective role when preventing simultaneously operation.
More preferably, as shown in Fig. 2, further including envelope star contactor KAY in the first circuit main contactor KMY of master control system 5,
It seals star contactor KAY to interconnect with master control system 5 and the second rescue system 6 simultaneously, master control system and the second rescue system share one
A envelope star.When master control system 5 or the second 6 driving traction machine 1 of rescue system, the normally-closed contact of envelope star contactor KAY is opened.KMY
Motor power contactor coil go for power supply, the coil of envelope star contactor KAY first will be powered, and make to seal star contactor
The normally opened closure of KAY, while safety relay KAD coil will also be powered (i.e. safety return circuit closure), safety relay KAD's is normal
Opening and closing is closed.Envelope star contactor KMY coil has electricity at this time, is the normally opened contact closure for controlling 1 power supply of traction machine, and traction machine 1 is powered,
Prepare operating.Brake loop conducting (see brake loop circuit diagram Fig. 4 and Fig. 5) at this time, band-type brake are opened, and traction machine 1 starts running.
Operation contactor will be attracted earlier than band-type brake contactor.The setting for sealing star contactor cleverly disconnects when traction machine is run,
Three-phase electric short circuit is prevented, and is not exported in KMY, when traction machine is static, short circuit prevents traction machine car slipping.Traction machine phase when car slipping
When that when being shorted three-phase electricity, can generate very big impedance in generator, when torque=impedance torque of car slipping, traction machine is just
It can travel at the uniform speed, prevent freely falling body bring impact damage.
