After 1 loses society's electrical network 10 power supply, its contact 3 automatically resets, and connects emergency power supply 9 and unit electrical network 11, to unit electrical network 11
Power supply.Because three electromagnetic switch are actions simultaneously, during so society's electrical network 10 has a power failure, emergency power supply 9 is simultaneously to unit electricity
Net 11 is powered；Again because connecting one group of reactor 12, it is possible to eliminating break contact 3 may delayed the connected moving together contact of reactor 12
2 instant cut-offs brought.
The energy storage type emergency power supply changing-over device that do not has a power failure provides the benefit that: achieves and enables emergency power supply automatization；Without stopping
Electricity gap powers, it is ensured that the power supply continuity of unit electrical network 11, it is to avoid the variation that transient-power failure brings.
