Description
Technical field
The utility model relates to a kind of accident emergency device, especially relates to a kind of alternating current-direct current emergency lighting switching device shifter.
Background technology
In industries such as electric power, industrial and mineral, hospital, hotel, markets; Must be equipped with emergency lighting and emergency lighting device; When burst accident takes place; The general lighting device is switched to emergency lighting device through the illumination switching device shifter,, avoid causing unnecessary injures and deaths and property loss with the reply burst accident.Present emergency lighting switching device shifter mainly adopts interchange, dc switch and contactor interlocking to reach the purpose of output DC behind the AC dump; But because output is direct current, can not output AC, greatly the influence of degree the multifarious requirement of present circuit load; Simultaneously; Because of it adopts traditional contactor, reach 0.3S second switching time, can not satisfy the requirement of power supply reliability.
The utility model content
The purpose of the utility model provides a kind of alternating current-direct current emergency lighting switching device shifter; Can adapt to the multifarious requirements of load such as present circuit inductance property, capacitive character and comprehensive load; With multiple automation equipment linkage work; Shorten emergency situations power supply switching time, satisfy the requirement of power supply reliability.
For realizing above-mentioned purpose; The utility model provides a kind of alternating current-direct current emergency lighting switching device shifter, comprises AC input terminal and direct-flow input end, and the utility model also comprises the signal processing center; Be connected with inverter and diverter switch in the said signal processing in the heart; Be connected with first filter on the said inverter, be connected with second filter on the said diverter switch, said second filter is connected with ac output end.
Preferably, also be connected with LED display lamp and LCD display in the said signal processing in the heart.
Preferably, also be connected with communication interface in the said signal processing in the heart.
Therefore; The utility model adopts the alternating current-direct current emergency lighting switching device shifter of said structure; Can adapt to the multifarious requirements of load such as present circuit inductance property, capacitive character and comprehensive load; With multiple automation equipment linkage work, shorten emergency situations power supply switching time, satisfy the requirement of power supply reliability.
Through accompanying drawing and embodiment, the technical scheme of the utility model is done further detailed description below.
