Technical field
The present invention relates to power supply fast-switching switch technical field, especially to a kind of dual power supply fast-switching switch.
Background technology
As power failure occurs frequently, such as：Have a power failure, under-voltage, over-pressed, disconnected phase, frequency shift (FS) etc., it is necessary to carry out power supply it
Between automatic switchover, to ensure the reliability and security of power supply, twin-power switch is widely used in skyscraper, cell, doctor
Institute, airport, subway, data center, elevator, precision manufactureing, chemical industry, the important place that does not allow to have a power failure such as prevent.However, traditional
Twin-power switch, still suffer from following weak point：（1）Switching time is more long, conventional switching time in 50 ~ 80ms, no
Security and stability can be provided for equipment；（2）Circuit-breaker switching on-off, arc extinguishing it is limited in one's ability；（3）Structure is single, adapts to field
Close few；（4）, it is necessary to spend the time to confirm whether power supply disconnects during Switching power, and switch by certain operation order, reduce switching
Efficiency, it is impossible to meet production requirement.
Described on end, existing twin-power switch is required to improve, and is improved particularly the speed of switching and the ability of arc extinguishing etc..
The content of the invention
It is an object of the invention to the deficiency for overcoming above-mentioned prior art to exist, and one kind is provided and is switched fast, arc extinguishing energy
Power is strong, adapts to occasion extensively, and automatically switches, to improve the dual power supply fast-switching switch of switching efficiency.
What the purpose of the present invention was achieved in that：
Dual power supply fast-switching switch, it is characterized in that, including upper incoming line row, upper vacuum bubbles, lower vacuum bubbles, lower lead-in line row, outlet
Row, linkage and divide-shut brake switching device, vacuum interrupter, vacuum extinction are respectively arranged with upper vacuum bubbles and lower vacuum bubbles
