If electronic equipment 10 determines sig before sending switching signal to the closing coil of high-voltage circuitbreaker1=" 1 ",
Show closing coil control loop breaker auxiliary normally opened contact closure.Further, electronic equipment 10 is to high-voltage circuitbreaker
After closing coil sends switching signal, to the digital signal sig of the normally opened auxiliary contact KA of intermediate relay 304Sentenced
It is disconnected: if sig4=" 1 " determines the normally opened auxiliary contact KA closure of intermediate relay 30, judges at this time and energy storage motor linkage
Assist the digital signal sig of normally-closed contact3Still " 1 " for " 0 ":
If sig3=" 1 " shows that energy storage motor is in charged state, and judgement links auxiliary with high-voltage circuitbreaker main shaft at this time
Help the digital signal sig of normally opened contact2Still " 1 " for " 0 ", if sig2=" 0 " shows to link with high-voltage circuitbreaker main shaft auxiliary
It helps the normally opened contact of switch BB1 to open, generates the third prompt information M of high-voltage circuitbreaker internal fault3And sound-light alarm is carried out,
By third prompt information M3It is shown in WinCC.
If sig3=" 0 ", shows that energy storage motor completes charging, judges that the auxiliary to link with high-voltage circuitbreaker main shaft is normal at this time
Open the digital signal sig of contact2Still " 1 " for " 0 ", if sig2=" 0 " shows that the auxiliary to link with high-voltage circuitbreaker main shaft is opened
The normally opened contact for closing BB1 is opened, and the 4th prompt information M of locking combined floodgate abnormal (RL1 is not closed) is generated4And carry out acousto-optic report
It is alert, by the 4th prompt information M4It is shown in WinCC.
Case3:
Electronic equipment 10 is before sending switching signal to the closing coil of high-voltage circuitbreaker, to closing coil control loop
The digital signal sig of breaker auxiliary normally opened contact1Judged, if sig1=" 1 " shows closing coil control loop open circuit
Device assists normally opened contact closure, further, after electronic equipment 10 sends switching signal to the closing coil of high-voltage circuitbreaker,

Optionally, electronic equipment 10 can also acquire the test position of the working position signal of high-voltage circuitbreaker, high-voltage circuitbreaker
Signal selection signal, disconnecting switch closure signal etc. and is shown using as basic status information in WinCC by remote machine
Prompt.Can also judge whether working position and test position are normal, if abnormal, can issue by the handcart position of BT1 and BT2
Corresponding sound and light alarm signal, in this way, improving the comprehensive of fault detection and plant maintenance.
Optionally, the fault cues of high voltage circuit breaker closing failure are checked for convenience, and WINCC points are drawn for key frame and son
Face, key frame show total state (normal or abnormal) of each high-voltage circuitbreaker, and green font is that fault-free is normal, red word
Body is malfunction, after click button enters sprite, shows that the specifying information of this vacuum circuit breaker, green font are fault-free
Normally, red font is malfunction, in another example, combined aural and visual alarm reset button can also be established on picture and restores alarm
Button.
In addition, can not only realize that automatic fault is sentenced by the logic control of electronic equipment 10 and the picture prompt of WinCC
It is disconnected, reduce fault handling time, moreover it is possible to inquire at any time the state of energy storage motor, to debug in time, avoid nothing
Method causes bigger accident when operating.
Further, there are 5 calculation of fault according to annual, can be saved the time every time by above-mentioned fault detection method
It is 0.5 hour, annual to save fault time 2.5 hours, consider from drop pulling rate, equipment downtime, about 10,000 yuan of expense can be saved every year.
