Description
Technical field
The utility model relates to a kind of EPS power supply, specifically is a kind of EPS power supply of anti-lightning strike and anti-strong electromagnetic and High-frequency Interference.
Background technology
EPS power supply (emergency power supply) is for electric power safeguard and security against fire and a kind of emergency power supply that adopts in building.It mainly partly is made up of input-output unit, charging module, battery pack, inverter, watch-dog, output switching device shifter etc.Its principle is: at civil power just often, give the load power supply by civil power through the output switching device shifter, charger is that storage battery charges or floating charge simultaneously; When civil power outage back or voltage exceed supply district, controller starts inverter, and the while switching device shifter switches to inverter power supply immediately with the mains-supplied state, for load equipment provides emergency service; When the city power recovery, emergency power supply will revert to mains-supplied.
Existing EPS power supply is relatively poor in anti-lightning strike, anti-strong electromagnetic and High-frequency Interference aspect of performance, has influenced its operate as normal.
The utility model content
The technical problems to be solved in the utility model provides a kind of EPS power supply of anti-lightning strike and anti-strong electromagnetic and High-frequency Interference.
For solving the problems of the technologies described above, the EPS power supply of anti-lightning strike and anti-strong electromagnetic and High-frequency Interference that the utility model provides comprises: power line filter, be located at the varistor that is used to take shelter from the thunder of the end of incoming cables of power line filter, be located at the rectifier and the isolating transformer of the leading-out terminal of power-supply filter, be located at the inverter of the output of rectifier, the charging that links to each other with the secondary coil of isolating transformer, detect and drive circuit, with charging, the storage battery that the charge power supply output of detection and drive circuit links to each other, the power end of storage battery links to each other with the dc power supply terminal of described inverter with control switch through filtering capacitor successively; Be respectively equipped with the high frequency electromagnetic radiation radome on described charging, detection and drive circuit and the filtering capacitor; Holding wire between described charging, detection and drive circuit and the storage battery adopts shielded type cable.
The technique effect that the utlity model has: in the EPS power supply of anti-lightning strike and anti-strong electromagnetic and High-frequency Interference of the present utility model, adopt varistor to realize lightning-arrest function, weak current part adopts isolating transformer to power separately, holding wire adopts shielded type cable, power line filter is adopted in the end of incoming cables, interferes with each other inside and outside preventing; The strong and weak electricity module separately adopts the high frequency electromagnetic radiation radome separately, thereby makes EPS power supply of the present utility model have the function of anti-lightning strike, anti-strong electromagnetic and High-frequency Interference.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 is the structured flowchart of the EPS power supply of anti-lightning strike and anti-strong electromagnetic and High-frequency Interference among the embodiment.
Embodiment
Below in conjunction with drawings and Examples the utility model is elaborated:
As Fig. 1, the EPS power supply of anti-lightning strike and the anti-strong electromagnetic and the High-frequency Interference of present embodiment comprises: power line filter, be located at the varistor RV that is used to take shelter from the thunder of the end of incoming cables of power line filter, be located at the rectifier and the isolating transformer of the leading-out terminal of power-supply filter, be located at the inverter of the output of rectifier, the charging that links to each other with the secondary coil of isolating transformer, detect and drive circuit, with charging, the storage battery that the charge power supply output of detection and drive circuit links to each other, the power end of storage battery links to each other with the dc power supply terminal of described inverter with control switch K through filtering capacitor successively.
Be respectively equipped with the high frequency electromagnetic radiation radome on described charging, detection and drive circuit and the filtering capacitor; Holding wire between described charging, detection and drive circuit and the storage battery adopts shielded type cable.
Obviously, the foregoing description only is for the utility model example clearly is described, and is not to be qualification to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all execution modes.And these belong to conspicuous variation or the change that spirit of the present utility model extended out and still are among the protection range of the present utility model.
