Abstract
The utility model discloses a kind of accident lighting system, it comprises filter, storage battery, rectifier, inverter and static switch, described filter separates two-way output, the first via is connected with static switch with inverter through rectifier, the second tunnel is directly connected with static switch, and described static switch is also connected with filter; Described storage battery is through between anti-polarity misconnection bridge road access rectifier and inverter.This system configuration is simple, has solved overload, fault of converter and internal temperature too high and cause emergency lighting to use.
Description
Technical field
The utility model relates to a kind of accident lighting system, belongs to lighting field.
Background technology
Accident lighting system is as the emergency set under the power plant state of emergency, and its importance is self-evident.Emergency lighting is comparatively simple with regard to itself system configuration, belongs to easy unheeded device type, but its effect lose the safety in production that may badly influence power plant.
But when practical in some producers at present, easily there are following two kinds of problems:
One, because DC loop and ac circuit only switch through switching device shifter, there is common link circuit, this just makes the zero line of ac circuit and the negative pole of DC loop directly be connected, in this factory, be earthing mode and exchange zero line (neutral point), thereby drop into direct current system when direct current and will send out ground signalling, have influence on the normal operation of direct current system.
If two directly supply emergency lighting when exchanging after disappearance by direct current system, to make DC bus directly be connected with illuminator, and illuminator is not easy to prevent the generation of short circuit and ground connection, therefore when being short-circuited or meeting positive pole (negative pole has exchanged neutral ground) when ground connection again, will cause DC bus-bar voltage abnormal, badly influence the safe operation of full plant.
Summary of the invention
The utility model solves the problems of the technologies described above, and is to provide a kind of accident lighting system, and this system configuration is simple, has solved overload, fault of converter and internal temperature too high and cause emergency lighting to use.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of accident lighting system, it comprises filter, storage battery, rectifier, inverter and static switch, and described filter separates two-way output, and the first via is connected with static switch with inverter through rectifier, the second tunnel is directly connected with static switch, and described static switch is also connected with filter;
Described storage battery is through between anti-polarity misconnection bridge road access rectifier and inverter.
The voltage of described filter input is 380V.
Described battery tension is 220V.
The beneficial effects of the utility model are: in the time that inverter runs well, AC power is through filter filtering high-frequency harmonic and play electrical isolation effect, be made into direct current via rectifier again, and convert pure sine-wave power to through inverter, use finally by delivered to subscriber equipment by static switch, filter, in the time of AC power power-off, continue power supply to inverter by 220V storage battery, and to the pure sine-wave power of converting, again via static state and close, filter continue to deliver to subscriber equipment use, avoiding making load has circut breaking.
Brief description of the drawings
Fig. 1 is the utility model system configuration schematic diagram;
Fig. 2 is the utility model embodiment mono-structural representation.
In Fig. 2, solid line is that signal moves towards figure.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of accident lighting system, it comprises filter 1, storage battery 2, rectifier 3, inverter 4 and static switch 5, filter 1 separates two-way output, the first via is connected with static switch 5 with inverter 4 through rectifier 3, the second tunnel is directly connected with static switch 5, and static switch 5 is also connected with filter 10; Storage battery 2 accesses between rectifier 3 and inverter 4 through anti-polarity misconnection bridge road 6.The voltage that filter 1 is inputted is 380V.Storage battery 2 voltages are 220V.
In the time that inverter runs well, AC power is through filter filtering high-frequency harmonic and play electrical isolation effect, be made into direct current via rectifier again, and convert pure sine-wave power to through inverter, use finally by delivered to subscriber equipment by static switch, filter, in the time of AC power power-off, continue power supply to inverter by 220V storage battery, and to the pure sine-wave power of converting, again via static state and close, filter continue to deliver to subscriber equipment use, avoiding making load has circut breaking.
In the time occurring that overload, fault of converter and inverter internal temperature are too high, as shown in Figure 2,380V electric current, after filter, by being directly sent to static switch after filter filtering, then is given filter by static switch and is exported in subscriber equipment and use.
More than show and described general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
