One, the heavily moving part of backup auto-activating device breaker tripping and closing:
Because the contact rating of backup auto-activating device output is not enough, can not cut off the loop current of mimic-disconnecting switch, therefore need carry out heavily moving to the contact of backup auto-activating device output to increase contact rating.Structure Figure 12 and Figure 13 briefly introduce the heavily moving circuit theory figure of backup auto-activating device breaker tripping and closing: because our isolating switch that backup auto-activating device connected has 4 (high-pressure side of working power and low-side switch, the high-pressure side of standby power supply and low-side switch.), so Figure 12 has comprised the heavily moving loop of the breaker tripping and closing contact of 4 switches.KOM1 and KOM2 are respectively the tripping working power high-pressure side and the low-side switch tripping operation contact of backup auto-activating device output among Figure 12, start the heavy motor type relay KCO1 of tripping operation and KCO2, mimic-disconnecting switch KM1 and the KM2 among tripping Figure 13 then respectively.
Two, mimic-disconnecting switch and voltage, current switching portion:
Because backup auto-activating device action needs certain condition: 1, charge condition: the three-phase voltage of working power is 57.7V, a phase current has the electric current existence, and high-pressure side and low-side switch are at closing position; 2, operation condition: the high and low pressure side isolating switch failover reason tripping operation of working power or switch are stolen and are jumped, the voltage of working power, current vanishes, and backup power source voltage is normal.Have only and satisfy above two conditions, backup auto-activating device could correct operation.In order to satisfy two conditions of prepared auto restart action, we have designed mimic-disconnecting switch and voltage, electric current, switching part, principle such as Figure 13.Principle is introduced: 1. QF1 is that fast switch-dividing control mimic-disconnecting switch KM1 and KM2 close a floodgate; When fast switch-dividing QF1 closed, mimic-disconnecting switch KM1 and KM2 action output normal opened contact were given backup auto-activating device, and the high-pressure side of analog operation power supply and low-side switch are at closing position; The auxiliary contact that utilizes KM1 and KM2 simultaneously is voltage, the current return of WV and current switching to prepared auto restart; The normal operating condition of analog operation power supply, in this state, the backup auto-activating device charging of can delaying time.2. break off fast switch-dividing QF1 after charging is accomplished; Mimic-disconnecting switch KM1 and KM2 are because of the dead electricity tripping; Therefore the backup auto-activating device closing position contact of power source voltage, electric current and isolating switch of can losing the job, tripping operation of mimic-disconnecting switch failover reason or switch are stolen the state of jumping like this.3. since the operation condition of prepared auto restart require backup power source voltage normal, therefore standby voltage transfer relay KM5 is set, when closing fast switch-dividing QF2, switch to backup auto-activating device to voltage, simulate prepared auto restart standby voltage loop like this.4. backup auto-activating device correct operation after satisfying operation condition is exported KC1 and KC2 combined floodgate contact, and standby power supply mimic-disconnecting switch KM3 and KM4 close.Through above introduction, the heavily moving reliably action logic of verification " backup auto-activating device " that partly cooperatively interacts of mimic-disconnecting switch and voltage, electric current, switching part and backup auto-activating device breaker tripping and closing, and need not the primary equipment of stopping using.
Three, control, display part
Control, display part effect are: 1, control device internal actions logic; 2, be connected with the contact loop with electric current, the voltage of backup auto-activating device; 3, the state of display simulation isolating switch; 4, guarantee the power supply supply.
Technical scheme of the present invention is not restricted in the scope of embodiment of the present invention.The present invention not technology contents of detailed description is known technology.
