请教320APU启动好之后关掉2块电瓶APU是否会自动停车，原因何在？

保护性关车
An AUTO SHUT DOWN occurs in case of:
- overspeed,
- overtemperature,
- Low Oil Pressure (LOP),
- High Oil Temperature (HOT),
- no flame,
- no acceleration,
- low acceleration rate,
- deceleration during start sequence,
- surge/reverse flow,
- generator high oil temperature,
[color=#FF0066]- loss of DC power,
- underspeed,
- loss off speed,
- sensor failure,
- air intake not open,
- ECB failure.

个人认为不会，当APU启动成功，给飞机电网供电时，直流汇流条都有电了，怎么还会存在loss of DC power。

而且我以前看到我们公司有的飞行员用外部电源启动APU，都不开电瓶。但我要强调的只限制与A320系列。A330又是另外一种情况！

ECB控制APU的工作，它的供电来源如下：
The battery bus 301PP supplies 28VDC to the ECB 59KD through the circuit breaker ECB SPLY 1KD and the relay APU MAIN 4KD. The 28VDC supply for the APU MAIN relay is through the circuit breaker APU CTL 2KD. The ECB continuously monitors its internal voltages and starts an APU shutdown if a voltage failure occurs (that would result in an unsafe operation of the APU).
The aircraft power supply allows the ECB 59KD to continue to control the APU during short power interruptions on the battery busbar 301PP. It will do this when the APU speed is more than 95 %.
The PMG supply installed in the cooling fan (Ref. 49-52-00) allows the ECB 59KD to continue to control the APU during short power interruptions on the battery busbar 301PP. It will do this when the APU speed is more than 70%.
综上所述，APU启动好之后关掉2块电瓶，会自动停车！如有不对之处，还望各位指出！
