3. operation principle and the key technical indexes: automatic controller is monitored power supply commonly used that is moving and the stand-by power supply of preparing conversion at any time.In the three-phase of power supply commonly used, there is any phase voltage unusual (fault) to occur, disappears (Un=0) as overvoltage (〉=120% rated voltage Un), under voltage (≤70%Un)) or power supply, through suitable delay time t
1(t
1Adjustable, be 60s to the maximum, the time-delay purpose is to observe this kind electric voltage exception not have and may disappear in short-term, replys normal condition).Confirming that power supply commonly used can't recover normally just will use power supply always and cut off automatically, passes through t again
2Time-delay, with the circuit breaker of the stand-by power supply (t that closes
2Be 1.5s to the maximum, t
2Comprise that auxiliaries-supply circuit-breaker receives instruction and its intrinsic closing time).If power consumption equipment changes stand-by power supply power supply over to, after a period of time, the fault of normal power source is got rid of, and has recovered normal, user's normal power source of intending again to reuse, and then controller is through certain delay time t
3(t

4Time-delay (t
4The longest is 1.5s), the circuit breaker of the normal power source that closes then.Above process is referred to as to haul oneself willingly into runback.If there is two-way power supply (power supply I and power supply II) all to be in normal condition, automatic controller will not send any operational order, and at this moment, a power supply power supply is selected in available manual operation.Break down when using the power supply (for example power supply 1) of powering always, and another stand-by power supply (power supply II) is normal words that automatic controller enters the time-delay state immediately, through t
1Time-delay (t
1Identical with above-mentioned implication), the circuit breaker of power supply 1 is cut off, again after the 1s time-delay; The circuit breaker of power supply 11 is closed.This process is called hauls oneself willingly into not runback.If stand-by power supply is a diesel engine generator, its transfer process is: when normal power source breaks down, through t
1Time-delay, confirm power supply commonly used can't according to multiple normal after, just will use the circuit breaker cut-out of power supply always. again through t
2Time-delay (t
2Be generally 1.5s, this is the time of quick self-starting diesel engine generator starting, generating), when confirming that stand-by power supply has been in the Hot Spare state, pass through t again
3(t
3≤ 1.5s), the circuit breaker of stand-by power supply is closed.
For the operating room in the modernized hospital, preparation room, special ICU; Preemie chamber etc. (and similarly some places), it allows power interruptions time is 0.5s, some instantaneous special stand-by power supplies, the user that 0.5s even shorter time will drop into, that the time can be transferred is shorter.
About overvoltage, determine 120%Un as maximum, consider the breakdown voltage (producing the voltage of stall) of circuit and equipment (for example motor), the setting value value of under voltage is decided to be 70%Un.For satisfying user's needs, product can accomplish that under voltage is adjustable, and its scope is 60%~85% Un; Overvoltage is adjustable, and its scope is 110%~130% Un.Transfer delay, conversion outage time-delay, return time-delay etc. also for adjustable.When power supply commonly used moves, if stand-by power supply occurs unusual, because automatic controller monitors this two power supplys always, the warning (sending beeping sound by buzzer) of will breaking down this moment is in time repaired with the announcement operating personnel, make stand-by power supply when needed, can safety, come into operation reliably.In case commonly used and stand-by power supply all breaks down, two circuit breakers of automatic controller military order all disconnect, and all are in the open position of non-combined floodgate.
