Technical field
The utility model relates to a kind of electronic installation, particularly relates to a kind of backup auto-activating device of tool pattern recognition function.
Background technology
Backup auto-activating device is come into operation the automatically abbreviation of device of stand-by power supply.In electrical production and supply process, for guaranteeing power supply reliability, reduce to greatest extent the user is had a power failure, transformer station and responsible consumer generally adopt duplicate supply or many power supplys stand-by power supply mode each other, being equipped with automatics is the intelligent control device of realizing this function, and its safe and reliable operation is to guarantee that power supply is equipped with the successful key of throwing.
In electric power system, the operational mode of primary system may change as required.For the self adaptation primary system, prepared auto restart also has multiple operational mode, but all follows following general provisions basically:
1. working bus bar decompression (non-PT broken string cause);
2. the circuit breaker that is connected with former working power of tripping is in order to avoid stand-by power supply closes a floodgate in fault;
3. check whether stand-by power supply is qualified, as the circuit breaker that working bus bar links to each other with stand-by power supply that then closes that meets the demands;
4. prepared auto restart only moves once.
The 10KV bus of 110KV and above electric substation all is to adopt single-trunk segmental wiring basically in the electric power system, because electrical network constantly enlarges, the three-phase shortcircuit electric current of 10KV side also strengthens thereupon, make the 10KV electric power system all can only adopt fanout operation, and load generally all is to be connected to respectively on two sections 10KV buses, therefore just has mutual switching problem.Past is that the switching between two power supplys is carried out in the employing manual operation basically, will prolong interruption duration like this, also can cause charged drawing switch sometimes.And present most 110KV transformer station has realized unattended duty, thus just require power utilization system to automatically switch, the present more employing of existing switching mode be to realize by relay control mode.

According to the difference of stand-by power supply, can be divided into stand-by power supply is that electric network source and stand-by power supply are two kinds of operation principles of generator power supply.
When stand-by power supply is electric network source, simultaneously power supply commonly used and stand-by power supply are monitored by the automatic switchover controller that electronic component is formed, when there is normal voltage power circuit breaker end of incoming cables commonly used, then no matter whether the disconnected device end of incoming cables of stand-by power supply has normal voltage, being always power circuit breaker commonly used connects, having only has arbitrary phase power source voltage to occur unusually in the three phase mains of power supply commonly used, even during phase shortage (phase failure), through time-delay (1S～30S, usually adjust and be 3S) just install afterwards and will use dump always automatically, after stand-by power supply is closed in (1S～30S, adjusting usually is 3S) time-delay.When power up commonly used just often, then controller can be delayed time and stand-by power supply be cut off after (1S～30S, adjusting usually is 3S), after (1S～30S, adjusting usually is 3S), will use power supply always and close then.
According to statistics, the power outage that causes because of backup auto-activating device tripping and malfunction still accounts for suitable ratio in the electric power system power outage.Because adopt the device association complexity of duplicate supply or multi-power system power supply, have multiple operational mode, but can't finely take into account between multiple mode.As above-mentioned A, it might be circuit breaker A under the circuit breaker C situation that two circuit breakers of B add between two sections buses, and the C closure also may be circuit breaker B, and the C closure also might circuit breaker A, and B closure, circuit breaker C disconnect.When perhaps having the conversion of multiple operational mode, at this moment backup auto-activating device is not known current system running pattern, can't know which kind of will select handle cooperating current system running pattern, and then can't finely control and operate.On-the-spot realistic simulation test shows that backup auto-activating device changes supply power mode because of needs or power failure can't be carried out.
