2. being in "on" position when chopper and upper and lower disconnecting switch, handle can not go to " maintenance " or " disjunction " position, it is to avoid point chopper by mistake, when handle is in " disjunction " position, can only the upper and lower disconnecting switch of splitting or integrating, it is impossible to close chopper, it is to avoid falsely close circuit breaker.
3., when the non-separating brake of upper and lower disconnecting switch, earthed switch would not close, and handle can not forward to from " disjunction " position " maintenance " position, can prevent live connection of ground wire.
4. the non-separating brake of earthed switch, upper and lower disconnecting switch would not be closed, and can prevent line with ground from closing upper and lower disconnecting switch.
As follows in concrete operations:
1. power failure operation
10kV lands pre-payment complexes and is in operating position, i.e. tri-station isolating switch and high-pressure vacuum breaker is in "on" position, is in charging operation, and now handle is in " work one " position.Dividing chopper, handle forwards " disjunction " position to, and at this moment chopper can not close a floodgate, and handle hole movable tongue is unlocked, and will reverse, point disconnecting switch, conjunction earthed switch in operation handle update hole.Take out operation handle, at this moment can forward handle to " maintenance " position from " disjunction " position, now handle hole movable tongue is turned off, and power failure operation is complete, can observe whether disconnecting switch disconnects by observation window, then switch gear room and line-in and line-out chamber can be safeguarded and overhaul by maintainer.
2. power transmission operation
Overhaul complete, forwarding handle to " disjunction " position from " maintenance " position, chopper can not close a floodgate, and handle hole movable tongue is unlocked, by clockwise in operation handle update hole, divide earthed switch, close disconnecting switch, take out operation handle, handle is forwarded to " work " position from " disjunction " position, now handle hole movable tongue is turned off, at this moment can be by breaker closing, power transmission end of operation.
In actual applications, four apex of casing 1 upper cover are respectively provided with a temperature sensor and a humidity sensor, wherein the temperature and humidity of four temperature sensors and four humidity sensor measurements respectively is T1, T2, T3, T4, and H1, H2, H3, H4, obtains temperature value T and humidity value H after being handled as follows respectively:
T11=0.15 × T1+0.2 × T2+0.25 × T3+0.4 × T4；
T12=0.15 × T3+0.2 × T4+0.25 × T1+0.4 × T2；
H11=0.18 × H1+0.26 × H2+0.22 × H3+0.34 × H4；
H12=0.18 × H2+0.26 × H4+0.22 × H1+0.34 × H3；
Temperature value T when after treatment exceedes default temperature threshold M and/or humidity value H when exceeding default humidity threshold N, automatically power failure operation is carried out, observe whether tri-station isolating switch disconnects by observation window, then switch gear room and line-in and line-out chamber are safeguarded and overhaul by maintainer, carry out power transmission operation after maintenance.
