Both ends are parallel with resistance.
This intelligent substation checks and accepts the operation principle of breaker controller in analogue system：
1st, closing by hand：
1）220V DC positive powers are by closing by hand switch SA1, the normally closed electric shock KM2-0 accesses hand of manual brake separating relay
The actuating coil of dynamic closing relay KM1 relays, finally flow back to the negative pole of dc source.
2）When closing by hand switch SA1 closes a floodgate, manual brake separating switch SA2 is not "on" position, then manual brake separating relay
KM2 electric must not work, therefore manual brake separating relay normally closed contact KM2-0 is closure state, namely be switched by closing by hand
The combined floodgate starting-up later time that SA1 and manual brake separating relay normally closed contact KM2-0 concatenations are formed is conducting state.Combined floodgate starting-up later time
After conducting, closing by hand relay KM1 energization work, now, closing by hand relay normally open contact KM1-1 switches to closed form
State, closing by hand relay normally closed contact KM1-0 switch to off-state.
3）Because it is now gate-dividing state, therefore closing relay normally closed auxiliary contact DL-10 is closure state, so,
The closing by hand being made up of closing by hand relay normally open contact KM1-1 and closing relay normally closed auxiliary contact DL-10 concatenations
Loop is closure state so that closing relay HQ obtains electric work, closing by hand start completion.Closing relay HQ obtains electric work
When, closing relay normally closed auxiliary contact DL-10 switches to off-state by closing, the normally opened auxiliary contact DL- of closing relay
11 switch to closure state by disconnection.Under closing by hand state, separating brake relay normally closed auxiliary contact DL-20 is also at closure
State.Therefore, it is made up of separating brake relay normally closed auxiliary contact DL-20 and the normally opened auxiliary contact DL-11 concatenations of closing relay
Combined floodgate keep loop be also closure state so that closing relay HQ continues to remain powered on working condition.In closing by hand shape
Under state, closing by hand relay normally closed contact KM1-0 is off-state, therefore, by closing by hand relay normally closed contact KM1-0
The remote control closing circuit formed with closing relay normally closed auxiliary contact DL-10 concatenations is off-state, namely remote control combined floodgate is defeated
Closing relay HQ can not be passed to by intelligent apparatus by entering signal.So, it is invalid to be remotely controlled when ensuring that manual control, realizes
Remote control and the mutual locking controlled manually.
4）Closing by hand switch SA1, manual brake separating switch SA2 close a floodgate simultaneously when, due to being in series with combined floodgate starting-up later time
Manual brake separating relay normally closed contact KM2-0, therefore when manual brake separating relay KM2 obtains electric work, manual brake separating relay is normal
Closed contact KM2-0 disconnects, that is to say, that and combined floodgate starting-up later time can not turn on, and closing by hand relay KM1 can not obtain electric work,
Closing by hand order is invalid.
2nd, manual brake separating：
1）220V DC positive powers access manual brake separating relay KM2 actuating coil by manual brake separating switch SA2, most
The negative pole of power supply is flowed back to eventually.
2）Manual brake separating switch SA2 closures, closure is in by the manual brake separating switch SA2 separating brake starting-up later times directly constituted
State, therefore manual brake separating relay KM2 energization work.Now, manual brake separating relay normally closed contact KM2-0 is converted to by closing
Off-state, therefore closing by hand relay KM1 combined floodgate starting-up later time has been cut off, therefore closing by hand relay KM1 can not lead to
Electricity work, realizes interlocking.
3）After manual brake separating relay KM2 energization work, manual brake separating relay normally open contact KM2-1 is converted to by disconnecting
Closure state.Again because the normally opened auxiliary contact DL-11 of closing relay be now in closure state, therefore, by manual brake separating after
Manual brake separating loop in series the electrical equipment normally opened contact KM2-1 and normally opened auxiliary contact DL-11 of closing relay is also closure
State, separating brake relay TQ obtain electric work.While separating brake relay TQ obtains electric, separating brake relay normally closed auxiliary contact DL-20
Disconnect, causing to close a floodgate keeps loop to disconnect, closing relay HQ dead electricity, separating brake success.Now, the normally opened auxiliary of closing relay is touched
Point DL-11 disconnects, and closing relay normally closed auxiliary contact DL-10 recovers closure state, by closing relay normally closed auxiliary contact
The separating brake that DL-10 is formed keeps loop to obtain electric work, and separating brake relay TQ remains powered on working condition.Due to now manual brake separating
Relay normally closed contact KM2-0 is off, therefore by manual brake separating relay normally closed contact KM2-0 and closing relay
The remote control sub-gate circuit that normally opened auxiliary contact DL-11 is formed is also at off-state, causes remote control separating brake input signal to send to
Separating brake relay TQ path is cut off, therefore remote control separating brake input signal can not pass to separating brake relay TQ.That is, manually
It is invalid to be remotely controlled during control, ensure that remote control and manual mutual locking.
3rd, remote control is closed a floodgate：
1）Now be defaulted as gate-dividing state, therefore closing by hand relay normally closed contact KM1-0 is closure state, close a floodgate after
Electrical equipment normally closed auxiliary contact DL-10 is also closure state.The remote control switching signal that intelligent apparatus is sent（By being remotely controlled input of closing a floodgate
Terminal 107）The remote control formed via closing by hand relay normally closed contact KM1-0, closing relay normally closed auxiliary contact DL-10
Closing circuit accesses closing relay HQ, finally flows into power cathode, forms complete control loop, completes opening for remote control combined floodgate
It is dynamic.
2）After closing relay HQ work, the normally opened auxiliary contact DL-11 of closing relay switches to closure state by disconnecting,
Separating brake relay normally closed auxiliary contact DL-20 recovers closure state, therefore, by separating brake relay normally closed auxiliary contact DL-20 and
The combined floodgate that the normally opened auxiliary contact DL-11 of closing relay is formed keeps loop as closure conducting state.Power supply positive terminal 101 passes through
Close a floodgate and keep loop access closing relay HQ, finally flow back to power cathode terminal 102, closing relay HQ continues to be held on
State.
4th, it is remotely controlled separating brake：
1）Now system default is "on" position, and therefore, the normally opened auxiliary contact DL-11 of closing relay is closure state,
Manual brake separating normally-closed contact KM2-0 is closure state, and normally opened auxiliary by manual brake separating normally-closed contact KM2-0 and closing relay
The remote control sub-gate circuit for helping DL-11 concatenations in contact to form is also closure conducting state.The remote control sub-gate signal that intelligent apparatus is sent
（By being remotely controlled separating brake input terminal 137）Through being remotely controlled sub-gate circuit access separating brake relay TQ, power cathode is finally flowed back to, is formed
Complete control loop, complete the startup of remote control separating brake.
2）After separating brake relay TQ work, closing relay normally closed auxiliary contact DL-10 reverts to closure state, therefore,
The separating brake being separately formed by closing relay normally closed auxiliary contact DL-10 keeps loop to be in closure conducting state.Positive source
Terminal 101 accesses separating brake relay TQ through closing relay normally closed auxiliary contact DL-10, finally flows back to power cathode terminal 102,
Separating brake relay TQ continues to tend to remain on.
5th, combined floodgate function for monitoring：
1）The combined floodgate monitoring signal that intelligent apparatus is sent（By closing a floodgate, monitoring input terminal 106 is sent）Through separating brake relay
After normally closed auxiliary contact DL-20, power cathode terminal 102 is finally flowed back to, forms complete control loop.
During original state, if closing relay HQ does not work, and separating brake relay TQ works, then now separating brake relay
Normally closed auxiliary contact DL-20 is off-state, and the monitoring input terminal 106 that closes a floodgate can not be connected with power cathode terminal 102, feed back
Circuit-breaker status signal be exactly gate-dividing state signal.Opposite, if closing relay HQ works, and separating brake relay TQ is not
Work, then now separating brake relay normally closed auxiliary contact DL-20 is closure state, and the monitoring input terminal 106 that closes a floodgate is born with power supply
Extreme son 102 is connected, and the circuit-breaker status signal of feedback is exactly "on" position signal.

Dynamic circuit connector lock；2) manual brake separating；3）Remote control is closed a floodgate；4）It is remotely controlled separating brake.
This intelligent substation checks and accepts the operation principle of breaker controller in analogue system：
1st, closing by hand：
220V DC positive powers are manual by closing by hand switch SA1, the normally closed electric shock KM2-0 accesses of manual brake separating relay
The actuating coil of closing relay KM1 relays, finally flow back to the negative pole of dc source.
When closing by hand switch SA1 closes a floodgate, manual brake separating switch SA2 is not "on" position, then manual brake separating relay KM2
Electric it must not work, therefore manual brake separating relay normally closed contact KM2-0 is closure state, namely SA1 is switched by closing by hand
The combined floodgate starting-up later time formed with manual brake separating relay normally closed contact KM2-0 concatenations is conducting state.Combined floodgate starting-up later time is led
After logical, closing by hand relay KM1 energization work, now, closing by hand relay normally open contact KM1-1 switches to closed form
State, closing by hand relay normally closed contact KM1-0 switch to off-state.
Because it is now gate-dividing state, therefore closing relay normally closed auxiliary contact DL-10 is closure state, so, by
The closing by hand that closing by hand relay normally open contact KM1-1 and closing relay normally closed auxiliary contact DL-10 concatenations are formed returns
Road is closure state so that closing relay HQ obtains electric work, closing by hand start completion.Closing relay HQ obtains electric work
When, closing relay normally closed auxiliary contact DL-10 switches to off-state by closing, the normally opened auxiliary contact DL- of closing relay
11 switch to closure state by disconnection.Under closing by hand state, separating brake relay normally closed auxiliary contact DL-20 is also at closure
State.Therefore, it is made up of separating brake relay normally closed auxiliary contact DL-20 and the normally opened auxiliary contact DL-11 concatenations of closing relay
Combined floodgate keep loop be also closure state so that closing relay HQ continues to remain powered on working condition.In closing by hand shape
Under state, closing by hand relay normally closed contact KM1-0 is off-state, therefore, by closing by hand relay normally closed contact KM1-0
The remote control closing circuit formed with closing relay normally closed auxiliary contact DL-10 concatenations is off-state, namely remote control combined floodgate is defeated
Closing relay HQ can not be passed to by intelligent apparatus by entering signal.So, it is invalid to be remotely controlled when ensuring that manual control, realizes
Remote control and the mutual locking controlled manually.
Closing by hand switch SA1, manual brake separating switch SA2 close a floodgate simultaneously when, due to being in series with hand in combined floodgate starting-up later time
Dynamic separating brake relay normally closed contact KM2-0, therefore when manual brake separating relay KM2 obtains electric work, manual brake separating relay is normally closed
Contact KM2-0 disconnects, that is to say, that combined floodgate starting-up later time can not turn on, and closing by hand relay KM1 can not obtain electric work, hand
Dynamic circuit connector lock order is invalid.
2nd, manual brake separating：
220V DC positive powers access manual brake separating relay KM2 actuating coil by manual brake separating switch SA2, finally
Flow back to the negative pole of power supply.
Manual brake separating switch SA2 closures, closed form is in by the manual brake separating switch SA2 separating brake starting-up later times directly constituted
State, therefore manual brake separating relay KM2 energization work.Now, manual brake separating relay normally closed contact KM2-0 by close be converted to it is disconnected
Open state, therefore closing by hand relay KM1 combined floodgate starting-up later time has been cut off, therefore closing by hand relay KM1 can not be powered
Work, realizes interlocking.
After manual brake separating relay KM2 energization work, manual brake separating relay normally open contact KM2-1 is closed by disconnecting being converted to
Conjunction state.Again because the normally opened auxiliary contact DL-11 of closing relay is now in closure state, therefore, by manual brake separating relay
Manual brake separating loop in series the device normally opened contact KM2-1 and normally opened auxiliary contact DL-11 of closing relay is also closed form
State, separating brake relay TQ obtain electric work.While separating brake relay TQ obtains electric, separating brake relay normally closed auxiliary contact DL-20 breaks
Open, causing to close a floodgate keeps loop to disconnect, closing relay HQ dead electricity, separating brake success.Now, the normally opened auxiliary contact of closing relay
DL-11 disconnects, and closing relay normally closed auxiliary contact DL-10 recovers closure state, by closing relay normally closed auxiliary contact DL-
10 separating brakes formed keep loop to obtain electric work, and separating brake relay TQ remains powered on working condition.Due to now manual brake separating after
Electrical equipment normally-closed contact KM2-0 is off, therefore normal by manual brake separating relay normally closed contact KM2-0 and closing relay
The remote control sub-gate circuit for opening auxiliary contact DL-11 compositions is also at off-state, causes to be remotely controlled separating brake input signal sending to point
Lock relay TQ path is cut off, therefore remote control separating brake input signal can not pass to separating brake relay TQ.That is, control manually
It is invalid to be remotely controlled when processed, ensure that remote control and manual mutual locking.
3rd, remote control is closed a floodgate：
Now it is defaulted as gate-dividing state, therefore closing by hand relay normally closed contact KM1-0 is closure state, combined floodgate relay
Device normally closed auxiliary contact DL-10 is also closure state.The remote control switching signal that intelligent apparatus is sent（By being remotely controlled combined floodgate input
Son 107）The remote control formed via closing by hand relay normally closed contact KM1-0, closing relay normally closed auxiliary contact DL-10 is closed
Closing relay HQ is accessed in lock loop, finally flows into power cathode, forms complete control loop, completes opening for remote control combined floodgate
It is dynamic.
After closing relay HQ work, the normally opened auxiliary contact DL-11 of closing relay switches to closure state by disconnecting, point
Lock relay normally closed auxiliary contact DL-20 recovers closure state, therefore, by separating brake relay normally closed auxiliary contact DL-20 and conjunction
The combined floodgate that lock relay normally open auxiliary contact DL-11 is formed keeps loop as closure conducting state.The ECDC of power supply positive terminal 101
Lock keeps loop access closing relay HQ, finally flows back to power cathode terminal 102, closing relay HQ continues to be held on shape
State.
4th, it is remotely controlled separating brake：
Now system default is "on" position, and therefore, the normally opened auxiliary contact DL-11 of closing relay is closure state, hand
Dynamic separating brake normally-closed contact KM2-0 is closure state, and by manual brake separating normally-closed contact KM2-0 and the normally opened auxiliary of closing relay
The remote control sub-gate circuit that DL-11 concatenations in contact are formed is also closure conducting state.The remote control sub-gate signal that intelligent apparatus is sent（It is logical
Cross remote control separating brake input terminal 137）Through being remotely controlled sub-gate circuit access separating brake relay TQ, power cathode is finally flowed back to, has been formed
Whole control loop, complete the startup of remote control separating brake.
After separating brake relay TQ work, closing relay normally closed auxiliary contact DL-10 reverts to closure state, therefore, by
The separating brake that closing relay normally closed auxiliary contact DL-10 is separately formed keeps loop to be in closure conducting state.Power positive end
Son 101 accesses separating brake relay TQ through closing relay normally closed auxiliary contact DL-10, finally flows back to power cathode terminal 102, point
Lock relay TQ continues to tend to remain on.
5th, combined floodgate function for monitoring：
The combined floodgate monitoring signal that intelligent apparatus is sent（By closing a floodgate, monitoring input terminal 106 is sent）It is normal through separating brake relay
After closing auxiliary contact DL-20, power cathode terminal 102 is finally flowed back to, forms complete control loop.
During original state, if closing relay HQ does not work, and separating brake relay TQ works, then now separating brake relay
Normally closed auxiliary contact DL-20 is off-state, and the monitoring input terminal 106 that closes a floodgate can not be connected with power cathode terminal 102, feed back
Circuit-breaker status signal be exactly gate-dividing state signal.Opposite, if closing relay HQ works, and separating brake relay TQ is not
Work, then now separating brake relay normally closed auxiliary contact DL-20 is closure state, and the monitoring input terminal 106 that closes a floodgate is born with power supply
Extreme son 102 is connected, and the circuit-breaker status signal of feedback is exactly "on" position signal.
