Abstract
The three phase emergency power source incldues DC/AC inverter, accumulator combination, change, bidirectional thyristor and monitor to control the previous mentioned parts. The present invention may be used to provide both AC and DC power source to various power equipment and lighting apparatus. The present invention has fast change-over speed between the inverter and the by-pass circuit, good continuity, small output oblique wave and high stability.
Description
The present invention relates to a kind of power electronic technology, particularly when civil power stops, the three phase emergency power source equipment that power or mains lighting supply can be provided and can monitor.
Traditional emergency power supply generally adopts generating set or UPS uninterrupted power supply, but generating set exists deficiency such as pollute the environment, start-up time is long; Existing UPS uninterrupted power supply can not solve the supply problem that long-time civil power stops power supply, the equipment that the incompatibility automaticity improves day by day is to the requirement of power supply, particularly to the requirements such as degree of purification of continuity, stability and the power supply of power supply itself, and the problems such as needs that can not satisfy centralized monitor.
The purpose of this invention is to provide a kind of three phase emergency power source that when long-time accident takes place, can high quality power supply is provided and can realize monitoring for power or lighting apparatus.
Technical scheme of the present invention is: three phase emergency power source comprises the DC/AC inverter, batteries and charger thereof, bidirectional triode thyristor, supervising device; But batteries combination in any; DC/AC inverter, batteries and charger thereof, bidirectional triode thyristor are controlled by supervising device all.
In order to realize providing DC power supply, be that the two ends of above-mentioned storage battery are connected the output as DC power supply with two output posts to a kind of improvement of described three phase emergency power source.
For solution equipment breaks down and can provide power supply when overhauling, a kind of improvement of described three phase emergency power source is, is parallel with between the output of the external power source input of above-mentioned this battery charger and bidirectional triode thyristor and exchanges bypass circuit.Exchanging bypass circuit controlled by supervising device.
The interchange bypass circuit can be in series by power conditioner and another bidirectional triode thyristor.The controlled end of power conditioner and another bidirectional triode thyristor all links to each other with supervising device.
Advantage of the present invention and good effect be, provides time of power supply to depend on the capacity of storage battery, and long time power can be provided; Has interchange, direct current output; Each parts moves under the coordination of supervising device, and the switch speed of inverter circuit and bypass circuit is fast, and continuity is good; The output oblique wave is little, the stability height.The present invention can be various device power and mains lighting supply is provided.
Below in conjunction with accompanying drawing embodiment is elaborated.
