Scope.
The invention provides a kind of breaker closing control loop template monitoring system, to realize to breaker closing control
Effective monitoring, the alarm of circuit breaking and outside combined floodgate condition fault information.
It is a kind of structure of breaker closing control loop template monitoring system provided in an embodiment of the present invention referring to Fig. 1
Schematic diagram, mainly includes breaker closing control loop template monitoring circuit and closing operation control loop.
The breaker closing control loop template monitoring circuit include dc source KM, microcomputer protecting controller 11,
The handcart operating position normal opened contact S9 of breaker, the first auxiliary normally closed contact QF1 of the breaker, spring energy-storage is normally opened connects
Point S1, closing coil HQ, the handcart work location aided rebroadcast normally closed contact S91 of the breaker, the second auxiliary of the breaker
Normally closed contact QF11 and spring energy-storage auxiliary normally closed contact S11.
Wherein, the positive pole of the dc source KM is by the small air switch positive terminal 101 of voltage, wherein connecting institute all the way
State the jump position monitoring green light HG of microcomputer protecting controller 11, the jump position monitoring green light HG connections digital relay and monitoring dress
Put 11 jump position relay coil TWJ, the jump position relay coil TWJ connections handcart operating position normal opened contact S9,
Handcart operating position normal opened contact S9 connections the first auxiliary normally closed contact QF1, the first auxiliary normally closed contact QF1
Connect the spring energy-storage normal opened contact S1, the spring energy-storage normal opened contact S1 connections closing coil HQ, the combined floodgate
Coil HQ connects the negative pole of the dc source KM by the small air switch negative terminal 102 of voltage.It is complete in shutting-brake control loop
When whole, the jump position monitoring green light HG of described microcomputer protecting controller 11 is bright, while described jump position relay coil TWJ is obtained
Electricity, the action of its relay auxiliary contact.
Another road of the positive pole of the dc source KM connects the one of the handcart work location aided rebroadcast normally closed contact S91
End, the other end of the handcart work location aided rebroadcast normally closed contact S91 connects the wiring of microcomputer protecting controller 11 first
Terminal 1nD5, the first binding post 1nD5 finally connect the negative power line binding post of the microcomputer protecting controller 11
P2。
One end of the second auxiliary normally closed contact QF11 and handcart work location aided rebroadcast normally closed contact S91 are in parallel even
Connect, microcomputer protecting controller the second binding post 1nD4 connections described in the other end, the second binding post 1nD4 finally connects
Meet the negative power line binding post P2 of the microcomputer protecting controller 11.
Spring energy-storage auxiliary normally closed contact S11 one end is connected in parallel with the described second auxiliary normally closed contact QF11,

Its reason is damaged, and also may be such that closing circuit is obstructed, and the jump position monitoring green light HG does not work, accordingly, and second auxiliary is normal
Contact QF11 is closed, normally closed state is maintained, the microcomputer protecting controller 11 can send " breaker is in sub-gate position " information, according to
This understands that the auxiliary of breaker first normally closed contact QF1 has the obstructed failure of contact.
Spring energy-storage contact and two groups of contacts of above-mentioned handcart type breaker position are same reasons.When spring storage is full
During energy, the spring energy-storage normal opened contact S1 closures, and spring energy-storage auxiliary normally closed contact S11 disconnects, now, microcomputer is protected
Shield measure and control device will not then send " spring unstored energy " warning message.Conversely, when bullet storage is less than energy, the spring energy-storage is normally opened
Contact S1 is not closed, and closing circuit can be made obstructed, is jumped position monitoring green light HG and is not worked, and spring energy-storage auxiliary normally closed contact
S11 is failure to actuate, and remains turned on, i.e., contact maintains normally closed state, and the microcomputer protecting controller 11 will send " bullet
The non-energy storage of spring " warning message.
When the outside combined floodgate condition of breaker closing control loop, handcart operating position normal opened contact S9, described as described
When a certain or certain several combined floodgate condition in the first auxiliary normally closed contact QF1 and spring energy-storage normal opened contact S1 do not possess,
The dc source KM will be respectively turned on its corresponding auxiliary contact, be switched to the microcomputer protecting controller 11, concurrently
Go out specific fault alarm information, realize the monitoring, alarming function of shutting-brake control loop broken string.Therefore, it can learn that microcomputer is protected in real time
The monitoring signals of measure and control device output are protected, to shutting-brake control loop failure cause, judges, is effectively arranged so as to take in time
Apply, it is ensured that breaker closing is quick, efficient, it is ensured that the safe and reliable operation of breaker.
Further to improve monitoring, alarming information, the present embodiment additionally provides breaker and closes position monitoring circuit and control loop
Break alarm loop.It is another breaker closing control loop template monitoring system provided in an embodiment of the present invention referring to Fig. 2
