Described calibrator of automatic bus transfer device main frame (1) can be identical with the existing check meter of UHV (ultra-high voltage) industry, also can mainly contain three parts and form: 1, the heavily moving part of backup auto-activating device breaker tripping and closing; 2, mimic-disconnecting switch and voltage, current switching portion 3, control, display section.
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 inadequate, can not cut off the loop current of mimic-disconnecting switch, therefore need to heavily move to increase contact rating to the contact of backup auto-activating device output.Structure Figure 12 and Figure 13, briefly introduce the heavily moving circuit theory figure of backup auto-activating device breaker tripping and closing: because the isolating switch that our backup auto-activating device connects 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.In Figure 12, KOM1 and KOM2 are respectively tripping working power high-pressure side and the low-side switch tripping operation contact of backup auto-activating device output, start respectively the heavy motor type relay KCO1 of tripping operation and KCO2, then mimic-disconnecting switch KM1 and the KM2 in tripping Figure 13.
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 electric current to exist, and high-pressure side and low-side switch are at closing position; 2, operation condition: the high and low pressure side isolating switch of working power is because of failure cause tripping operation or switch jump, the voltage of working power, current vanishes, and backup power source voltage is normal.Only have and meet above two conditions, backup auto-activating device could correct operation.In order to meet two conditions of prepared auto restart action, we have designed mimic-disconnecting switch and voltage, electric current, switching part, and principle is as Figure 13.Principle is introduced: 1. QF1 is that fast switch-dividing control simulation isolating switch KM1 and KM2 close a floodgate, when fast switch-dividing QF1 closes, mimic-disconnecting switch KM1 and KM2 action output normal opened contact are to backup auto-activating device, the high-pressure side of analog operation power supply and low-side switch are at closing position, the auxiliary contact that simultaneously utilizes KM1 and KM2 is voltage, the current return to prepared auto restart operating voltage and current switching, the normal operating condition of analog operation power supply, in this state, backup auto-activating device can time delay charging.2. the fast switch-dividing QF1 of the rear disconnection of having charged, mimic-disconnecting switch KM1 and KM2 are because of dead electricity tripping, therefore the backup auto-activating device closing position contact of voltage, electric current and isolating switch of power supply of can losing the job, mimic-disconnecting switch trips or the state of switch jump because of failure cause like this.3. due to 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, voltage is switched to backup auto-activating device, simulate like this prepared auto restart standby voltage loop.4. backup auto-activating device correct operation after meeting operation condition, exports KC1 and KC2 combined floodgate contact, and standby power supply mimic-disconnecting switch KM3 and KM4 close.By 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 without inactive primary equipment.
