Description
Technical field
The present invention relates to electric power system, specifically a kind of light being applied to the specialty light occasion such as video display, arenas, stage
Power supply region method.
Background technology
Based on the requirement of artistic effect, the specialty lamp lighting system such as video display, arenas, stage typically requires to part even
All light is adjusted.The electric power system of these professional lamp lighting systems, the light modulation that commonly used light-adjusting cabinet is concentrated
And power supply control.For example for large-scale arenas（Or studio）, it dims, straight circuit quantity can reach hundreds of road, or even
Thousand of roads, the controller switching equipment in these loops and lighting network control（I.e. light-adjusting cabinet）All install the room in a special setting concentratedly
Between silicon control indoor.Power supply department is delivered to silicon control room whole electricity, then carry out here the distribution of electricity, adjustment,
Control, be finally delivered to again on the light fixture in each loop.
Existing specialty light electric power system principle is shown in accompanying drawing 1, and wherein power supply mode is：Attract electricity from total switchgear house of building
Source enters the electric power incoming line power distribution cabinet 1 of silicon control room, and electric power incoming line power distribution cabinet 1 distributes to several power distribution cabinets by 9 electricity of cable
3, each power distribution cabinet 3 distributes to several light-adjusting cabinets 4 by 9 electricity of cable again, and each light-adjusting cabinet 4 then passes through internal distribution
Three-phase electricity is converted to single-phase electricity by part 13, and is assigned to each light modulation, straight circuit.The quantity of light-adjusting cabinet output loop, property
Matter and specification determine quantity, property and the specification of this loop socket.
Below by each light-adjusting cabinet be provided with two light modulation modules and two straight-through modules as a example illustrate, specifically each
It is less that light-adjusting cabinet is designed with power（Such as 2-3kW）The first light modulation module 16 and the first straight-through module 18, and power is larger
（Such as 5-6kW）The second light modulation module 17 and the second straight-through module 19.Wherein, the less light modulation of rated power, straight-through module
16th, 18 corresponding less first socket 7 of rated current（Such as 16A）, and the larger light modulation of rated power, straight-through module 17,19
Then correspond to the second larger socket 8 of rated current（Such as 32A）.
For the fixed positions such as face light, slap on the face, post light, ground flowing, back-up circuit, lower-powered first light modulation module
16 and first lead directly to module 18 directly passes through 3X4mm2Specification（It is 31A that copper core allows long-term work electric current）Cable 10 connect specified

But above-mentioned specialty light electric power system substantially use loop power supply mode, early in silicon control room just
Incoming power is assigned as finally using the quantity in loop, specification, property（Light modulation or straight-through）All determine, then supplied accordingly
Electric system connect up, after electric power system can only be finely adjusted, be difficult to carry out big adjustment.But lighting art no certain it
Rule, the different type of dramas, the directory, there is very big difference between artist.Where use lamp, used how many lamps, the lamp of what property, much
Power, is all intended to, according to directory requirement, director, dance ＆ art, the artistic opinion of light controller, be set by light controller or artist temporarily,
And constantly adjust and improve.Thus result in preset and cannot cover practical application point, and actually used loop rule cannot be met
Lattice, the situation of Property requirements, thus produce a series of problem：

Situation, so that quantity relative deficiency in loop when actually used；On the other hand, it is not that each performance is required for using all or big
Part supply system loop, the total loop quantity that common performance uses only accounts for the 10% ~ 20% of electric power system total loop quantity, loop
Quantity is definitely superfluous, causes cable, device resource to waste.
（2）Each property loop quantity relative deficiency and definitely surplus.Property due to each loop of electric power system（Light modulation is still
Straight-through）It has been previously determined, may there is system dimming loop（Or straight circuit）Quantity is returned with the light modulation being actually needed
Road（Or straight circuit）The unmatched situation of quantity, the dimming loop quantity of such as systemic presupposition is less than the light modulation being actually needed and returns
Way amount, or the straight circuit quantity of systemic presupposition is more than the straight circuit quantity that is actually needed, thus causing each property
The deficiency of loop quantity or surplus.
（3）The uncertainty of loop property.Due to a large amount of automatizatioies light fixture, new type light source light fixture is introduced in use,
Loop property is light modulation or leads directly to, and changes a lot it is impossible to determine, cause a lot of contradictions and accident in use.
（4）The possible of power loop not and definitely wastes.Due to each loop of electric power system power it has been determined that but
It is in actual use, the power in each loop of electric power system cannot cover light fixture actual power comprehensively, usually can encounter reality
The situation that border power demand is not inconsistent with loop settings power, if actually required power is more than loop settings power, can cause back
Road power relative deficiency；If actually required power is less than loop settings power, the part of partial circuit power can be caused to waste.
In actually used, most lamp powers that performance uses every time are far below installs power loop, causes the wasting of resources.
（5）Three-phase imbalance.Because in using, lamp position, quantity randomness are very big, the good loop of planned balance is no appointed
What meaning.In use, field balancing is difficult to because of the phase place that cannot confirm each socket again.So lighting system three-phase is not
Balance is inevitable outcome.
（6）, there is potential safety hazard in electric power system unreasonable structure.On the one hand, electric power system is not in dendritic, but is in
Plethora type, more than 1,000 kilowatt of three-phase electricity enters silicon control room, directly switchs to the single-phase electricity in more than 1,000 loop out.Three-phase is not
Balance, the change of electricity consumption causes silicon control room and main line groove region to there is major fire hazard.On the other hand, existing specialty light supplies
The loop quantity of electric system, position, specification and property are all installed in advance and are fixed, if wanting to be adjusted according to practical situation
Whole, distance temporary cable can only be overlapped, so both do not met Electrical Safety specification it is also possible to temporary cable occurring and may move
Contradiction between mechanism, causes new potential safety hazard.
（7）The wasting of resources, serious interference.As above-mentioned（1）To（4）Point is described, existing specialty light electric power system
Loop quantity, position, specification and property are all installed in advance and are fixed, and cannot be used according to all kinds, various scale afterwards
Light occasion or scene are adjusted, and do not reach use requirement or part resource is not utilized, cause the substantial amounts of wasting of resources,
A large amount of wastes of such as cable（Large-scale theater light cable copper consumption is more than 25 tons）, and these substantial amounts of cables, disturb model
Enclose big, take up room big（Light main line groove specification more than 1200*300,2）, installation workload is big（Light of stage engineering 90%
Above workload laying in cable）.
Sum it up, existing specialty light electric power system is due to using loop power supply mode, each electricity consumption loop quantity,
Position, specification and property are all installed in advance and are fixed, and according to practical situation cannot are reasonably in actual use
System adjustment, thus produce above-mentioned using inconvenience, installation workload be big, serious waste of resources, the problems such as violate Electrical Safety specification,
Hinder development and the application of light of stage.
