Phase line pole is different with neutral pole structure, causes phase line from the first power supply to the transfer process of second source, in
Property pole do not disconnected simultaneously with the neutral conductor of this two power supply always.Wherein, moment exists connects simultaneously with the neutral conductor of this two power supply
Situation about connecing.
The change-over switch of non-neutral line overlap structure, phase line pole and neutral pole structure are basically identical, in phase line from first
In power supply to the transfer process of second source, the neutral conductor is converted simultaneously from the first power supply to second source, and is deposited in transfer process
In the situation that neutral pole simultaneously switches off in short-term with the neutral conductor of this two power supply.
