Description
Technical field
The present invention relates to electric power system, a kind of light being applicable to the specialty light occasions such as video display, arenas, stage
Electric power system.
Background technology
Requirement based on artistic effect, the professional lamp lighting system such as video display, arenas, stage typically requires to part the most even
All it is adjusted.The electric power system of these specialty lamp lighting systems, commonly used light-adjusting cabinet carries out light modulation and the confession concentrated
Electric control.Such as large-scale arenas (or studio), its light modulation, straight circuit quantity can reach hundreds of road, the most thousand of
Road, the controller switching equipment in these loops and lighting network control (i.e. light-adjusting cabinet) are all installed concentratedly in the room of a special setting
Silicon control is indoor.Power supply department is delivered to silicon control room whole electricity, the most here carries out the distribution of electricity, adjusts, controls,
After be 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 is then by internal distribution
Three-phase electricity is converted to single-phase electricity by parts 13, and is assigned to each light modulation, straight circuit.The quantity of light-adjusting cabinet output loop, property
Matter and specification determine the quantity of this loop socket, character and specification.
It is provided with as a example by two light modulation modules and two straight-through modules by each light-adjusting cabinet below and illustrates, the most each
Light-adjusting cabinet is designed with the first light modulation module 16 and first of power less (such as 2-3kW) and leads directly to module 18, and power is bigger
The second light modulation module 17 and second of (such as 5-6kW) leads directly to module 19.Wherein, the light modulation that rated power is less, straight-through module
16, the first socket 7(such as 16A that 18 corresponding rated current are less), and the bigger light modulation of rated power, straight-through module 17,19
The second socket 8(such as 32A that then corresponding rated current is bigger).
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 3X4mm2The cable 10 of specification (copper core allows long-term work electric current to be 31A) connects specified
The first socket 7 that electric current is less；The second light modulation module 17 and second that power is bigger leads directly to module 19 and directly passes through 3X6mm2Rule
The cable 11 of lattice (copper core allows long-term work electric current to be 39A) connects the second socket 8 that rated current is bigger.
For the shift position such as top light, sidelight, each light modulation, straight circuit pass sequentially through grid top terminals case 5 and on grid top
Bar upper terminal case 6 on suspension rod is indirectly connected to respective socket.Wherein, by many between grid top terminals case 5 and bar upper terminal case 6

Group 19 employing specification is 3X6mm2Cable 11 as connecting line (connecing the second socket 8).
But above-mentioned specialty light electric power system substantially use loop power supply mode, as far back as silicon control room the most
Incoming power is assigned as the quantity in final utilization loop, specification, character (dim or straight-through) all determine, supplies the most accordingly
Electricity system wiring, after electric power system can only be finely adjusted, be difficult to carry out big adjustment.But lighting art without certain it
Rule, the different type of dramas, the directory, there is the biggest difference between artist.Where with lamp, use how many lamps, the lamp of what character, much
Power, is all intended to according to directory requirement, director, dance & art, the artistic opinion of light controller, light controller or artist set temporarily,
And constantly adjust and improve.Thus result in preset and cannot cover actual point of application, and actually used loop rule cannot be met
Lattice, the situation of Property requirements, thus produce a series of problem:
(1) relative deficiency of loop quantity and definitely surplus.Owing to the position in each loop of electric power system has fixed,
But actual lamp optical position layout is flexible and changeable, which results in: on the one hand, and electric power system circuit positions cannot be covered comprehensively
Cover actual circuit positions, cause part to need the position of electricity consumption there is no an electricity, and part has the embarrassment of electricity without the position of electricity consumption
Situation, to such an extent as to quantity relative deficiency in loop time actually used；On the other hand, it not that performance every time 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 superfluous, causes cable, device resource to waste.
(2) each character loop quantity relative deficiency and definitely surplus.Owing to the character in each loop of electric power system (dims still
Straight-through) it has been previously determined, system dimming loop (or straight circuit) quantity may be there is and return with the light modulation being actually needed
The unmatched situation of road (or straight circuit) quantity, the dimming loop quantity of such as systemic presupposition is returned less than the light modulation being actually needed
Way amount, or the straight circuit quantity of systemic presupposition is more than the straight circuit quantity being actually needed, thus cause each character
The deficiency of loop quantity or surplus.
(3) uncertainty of loop character.Due to a large amount of automatizatioies light fixture, new type light source light fixture is introduced in use,
Loop character is light modulation or leads directly to, and uses middle change a lot, it is impossible to determine, causes a lot of contradiction and accident.
(4) the possible of power loop wastes not and definitely.Due to each loop of electric power system power it has been determined that but
Being 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, then can cause back
Road power relative deficiency；If actually required power is less than loop settings power, then the part of partial circuit power can be caused to waste.
In actually used, most lamp powers that performance uses every time, far below installing power loop, cause the wasting of resources.
(5) three-phase imbalance.Owing in using, lamp position, quantity randomness are very big, the good loop of planned balance is without appointing
What meaning.Use middle field balancing again because cannot confirm that the phase place of each socket is difficult to.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 in
Plethora type, the three-phase electricity of more than 1,000 kilowatt enters silicon control room, directly transfers the single-phase electricity in more than 1,000 loop to out.Three-phase is not
Balance, the change of electricity consumption causes silicon control room and main line groove region to there is fire disaster hidden danger.On the other hand, existing specialty light supplies
Loop quantity, position, specification and the character of electricity system has been installed the most in advance and has been fixed, if wanting to adjust according to practical situation
Whole, distance temporary cable (guiding to actual lamp position from light-adjusting cabinet) can only be overlapped, the most both do not met Electrical Safety specification,
It may also happen that the contradiction between temporary cable and movable mechanism, cause new potential safety hazard.
(7) wasting of resources, serious interference.As described in above-mentioned (1st) to (4th) point, existing specialty light electric power system
Loop quantity, position, specification and character have been installed the most in advance and have been fixed, and cannot use according to all kinds, various scale afterwards
Light occasion or sight 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 (large-scale theater light cable copper consumption is more than 25 tons) of such as cable, and these substantial amounts of cables, disturb model
Enclosing big, take up room big (light main line groove specification more than 1200*300,2), big (the light of stage engineering 90% of installation workload
Above workload laying at cable).
Sum it up, existing specialty light electric power system is owing to using loop power supply mode, each electricity consumption loop quantity,
Position, specification and character have been installed the most in advance and have been fixed, and cannot be reasonably according to practical situation in actual use
Tracking is whole, thus produces the problem such as above-mentioned use inconvenience, installation workload big, serious waste of resources, violation Electrical Safety specification,
Hinder development and the application of light of stage.
Therefore, design one can according to the actual requirements lamp bit quantity, character and specification be adjusted, to adapt to not
With being specialty performance lamplight technical field technical barrier urgently to be resolved hurrily and existing by the performance lamplight electric power system of light application requirements
