Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of indoor power supply system in prior art;
Fig. 2 is the exemplary configurations schematic diagram of electric power system in the low-pressure chamber that provides of the utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Referring to Fig. 2, is the structural representation of electric power system in the low-pressure chamber that provides of the utility model one preferred embodiment.As shown in Figure 2, in low-pressure chamber, electric power system comprises for civil power (alternating current 220V) being converted to the Switching Power Supply 100 of target DC low-voltage, described Switching Power Supply 100 is arranged on registers one's residence in distribution box, and described target DC low-voltage meets the work requirements of small power DC electrical equipment 200.Conventionally, target DC low-voltage is direct current 36V, and small power DC electrical equipment 200 can comprise LED, Mobile phone charging socket etc.
Electric power system in the low-pressure chamber that the utility model provides, by Switching Power Supply 100 is installed in the distribution box of registering one's residence, make to register one's residence in distribution box out be exactly DC low-voltage, user (especially child) touches in the distribution box of registering one's residence arbitrary part of electric power system in low-pressure chamber out, for example, when cable, switch and electric equipment, what touch is all safe DC low-voltage, has avoided electric shock accidents, has ensured user's personal safety; Integrated switch power in small power DC electrical equipment 200 again, effectively reduces the design complexities of small power DC electrical equipment 200, solves the problem that its efficiency is low, driving power is too fat to move, improved reliability, reduce cost, reduced caloric value, extended its useful life; In addition, by Switching Power Supply 100 is arranged on and is registered one's residence in distribution box, not only improve security performance, but also improved the conversion efficiency of Switching Power Supply.
Wherein, can select mono-group of output switch power source of EHR series 200W, certainly, if needed, can be by the mode of a plurality of Switching Power Supply stacks being increased to the power of electric power system in low-pressure chamber.The direct voltage output of mono-group of output switch power source of EHR series 200W is 36V, and rated current is 5.9V, and rated power is 212.4W, and voltage adjusting range is 32-40V, and alternating voltage input is 2.5A/220V.
In indoor power supply system, conventionally adopt cable that the electric current of Switching Power Supply output is flowed to each household electrical appliance.At present, because operating current and the rated power of some household electrical appliance (such as refrigerator, water heater etc.) are larger, therefore conventionally use cut-out section for circular copper cash is as cable, this cable is conventionally hinged by some copper wires, to meet large electric current and powerful demand.The diameter of this cable need to be selected according to the power summation of all household electrical appliance.On the market, diameter is that the rated current of the cable of 2.5 square millimeters is about 15A, and diameter is that the rated current of the cable of 4 square millimeters is about 20A, the data that adopt when this is only also design, if local environment monthly mean temperature will convert in when more than 25 degrees Celsius, its formula is; The extraction of square root of permission electric current X* in the time of 25 degrees Celsius (long-term work temperature-ambient temperature/long-term work temperature-25), long-term work temperature is generally got 65 degree.In general, in order to strengthen extensibility, can select copper cash that diameter is larger as cable as far as possible.As can be seen here, in current indoor power supply system, often adopt thicker cable to connect up, in order not affect the appearance, this cable can only adopt concealed installation (on wall, to dig wire casing, cable is embedded in wall) mode install, this just need to be before house be fitted up, will design small power DC electrical equipment (for example LED lamp), the position of switch, and construct by the mode of pipe laying, such wire laying mode, lack flexibility, after house decoration, wiring can not be changed, and, if circuit breaks down, investigation is got up and is also bothered very much, even if found faulty line, maintenance also makes a great fuss.In order to address this problem, the interior electric power system of low-pressure chamber that the utility model provides has designed a kind of flat cable Switching Power Supply 100 has been communicated with small power DC electrical equipment 200, the cut-out section of described flat cable is rectangle, for example, due to the voltage transmitting in electric power system in this low-pressure chamber lower (being only 36V), operating current and the rated power of the small power DC electrical equipment 200 driving are all less, therefore the Thickness Design of flat cable can be obtained very thin, for example thickness is only 1 millimeter, is even less than 1 millimeter.Because flat cable is very thin, be attached on wall and almost cannot see, therefore can adopt bright dress mode to be laid immediately on indoor wall.Meanwhile, no matter be switch, still various adapters, socket, all adopt bright installing meter, and like this, in whole low-pressure chamber, electric power system can be carried out personalized design according to user's demand again after room has completed preliminary finishing.
Owing to having used above-mentioned flat cable, can also be correspondingly to be connected between Switching Power Supply 100 and small power DC electrical equipment 200, for the structural design of the switch of the connected state between control switch power supply 100 and small power DC electrical equipment 200, change, to adapt to the requirement of bright dress wiring and aesthetic property.The thickness of this ultra-thin switch 300 is 9-13 millimeter, is preferably 10 millimeters.
Correspondingly, can also design ultra-thin LED as small power DC electrical equipment, the thickness of described ultra-thin LED is 11-15 millimeter, is preferably 12 millimeters.
In addition, as shown in Figure 2, described system also comprises and is connected to described switch electricity, 100 and described ultra-thin switch between air switch 400, air switch 400 can be special-purpose four-way adapter (enters three modes that go out), and Jiang Yi road Splices cable becomes multiway cable.Air switch 400 can adopt ultrathin design equally, makes the design style of electric power system in whole low-pressure chamber all present a kind of modern sense and science and technology sense.
Above disclosed is only a kind of preferred embodiment of the utility model, certainly can not limit with this interest field of the utility model, one of ordinary skill in the art will appreciate that all or part of flow process that realizes above-described embodiment, and the equivalent variations of doing according to the utility model claim, still belong to the scope that utility model contains.
