Description
Technical field
The utility model relates to electric power system, specifically a kind of professional light electric power system with the light occasion such as video display, arenas, stage that is applicable to.
Background technology
Based on the requirement of artistic effect, the professional lamp lighting systems such as video display, arenas, stage need to even all be adjusted part usually.The electric power system of these professional lamp lighting systems, the light modulation and the power supply control that generally adopt light-adjusting cabinet to concentrate.For example for large-scale arenas (or studio), its light modulation, straight circuit quantity can reach the hundreds of road, even several thousand the tunnel, the controller switching equipment in these loops and lighting network control (being light-adjusting cabinet) all install concentratedly one special arrange the room---the silicon control is indoor.Power supply department is delivered to silicon control chamber to whole electric weight, then carries out distribution, adjustment, the control of electric weight here, is delivered on the light fixture in each loop at last again.
Existing professional light electric power system principle is seen accompanying drawing 1, wherein supply power mode is: attract the electric power incoming line power distribution cabinet 1 that power supply enters silicon control chamber from total switchgear house of building, electric power incoming line power distribution cabinet 1 is distributed to several power distribution cabinets 3 to electricity by cable 9, each power distribution cabinet 3 is distributed to several light-adjusting cabinets 4 to electricity by cable 9 again, each light-adjusting cabinet 4 then distribution member by inside 13 is converted to single-phase electricity with three-phase electricity, and is assigned to each light modulation, straight circuit.The quantity of light-adjusting cabinet output loop, character and specification have determined quantity, character and the specification of this loop socket.
The below is provided with two light modulation modules and two straight-through modules take each light-adjusting cabinet and describes as example, specifically each light-adjusting cabinet is provided with the first light modulation module 16 and the first straight-through module 18 of power less (for example 2-3kW), and power the second light modulation module 17 and the second straight-through module 19 of large (for example 5-6kW).Wherein, less the first socket 7(of the light modulation that rated power is less, straight-through module 16,18 corresponding rated current is 16A for example), the light modulation that rated power is larger, straight-through module 17,19 the second socket 8(that then corresponding rated current is larger be 32A for example).
For face light, slap on the face, post light, ground flow, the fixed position such as back-up circuit, lower-powered the first light modulation module 16 and the first straight-through module 18 directly pass through
The cable 10 of specification (it is 31A that the copper core allows the long-term work electric current) connects the first less socket 7 of rated current; The second light modulation module 17 that power is larger and the second straight-through module 19 directly pass through
The cable 11 of specification (it is 39A that the copper core allows the long-term work electric current) connects the second larger socket 8 of rated current.
For shift positions such as top light, sidelights, the grid top terminals case 5 that push up by grid successively each light modulation, straight circuit and bar upper terminal case 6 indirect joints on the suspension rod are to respective socket.Wherein, is connected by multicore row's cable or circle cable 12 between grid top terminals case 5 and the bar upper terminal case 6, in addition, lower-powered the first light modulation module 16 and the first straight-through module 18 employing specifications are
Cable 10 as connecting line (connecing the first socket 7), the second light modulation module 17 that power is larger and the second straight-through module 19 adopt specifications to be
Cable 11 as connecting line (connecing the second socket 8).
What yet above-mentioned professional light electric power system adopted in essence is the loop power supply mode, all determine as far back as quantity, specification, character (light modulation or straight-through) that silicon control chamber just has been assigned as final use loop to incoming power, then carry out accordingly the electric power system wiring, the back can only be finely tuned electric power system, is difficult to carry out large adjustment.But lighting art is without a fixed pattern, the different type of dramas, and there is very big-difference in the directory between the artist.Where use lamp, use how many lamps, the lamp of what character, much power all is will be according to directory requirement, director, dance ﹠ art, light controller's artistic opinion is set by light controller or artist temporarily, and is is constantly adjusted and improved.Therefore cause the preset can't cover the practical application point, and can't satisfy the loop specification of actual use, the situation that character requires, thereby produce a series of problem:
(1) relative deficiency of loop quantity and absolute superfluous.Because the position in each loop of electric power system fixes, but actual lamp optical position layout is flexible and changeable, this has just caused: on the one hand, the electric power system circuit positions can't cover actual circuit positions comprehensively, cause part to need the position of electricity consumption not have electricity, and part need not the awkward situation that there is electricity the position of electricity consumption, to such an extent as to loop quantity relative deficiency when reality is used; On the other hand, not that each performance all needs to use whole or most of electric power systems loop, the total loop quantity that common performance is used only accounts for 10% ~ 20% of electric power system total loop quantity, and loop quantity is definitely superfluous, causes cable, device resource waste.
(2) each character loop quantity relative deficiency and absolute superfluous.Because the character in each loop of electric power system (light modulation is still straight-through) is determined in advance, the unmatched situation of light modulation loop (or straight circuit) quantity that may have system's light modulation loop (or straight circuit) quantity and actual needs, for example the light modulation loop quantity of systemic presupposition is less than the light modulation loop quantity of actual needs, or the straight circuit quantity of systemic presupposition is more than the straight circuit quantity of actual needs, thereby causes the not enough or superfluous of each character loop quantity.
(3) uncertainty of loop character.Because a large amount of automation light fixtures, the new type light source light fixture is introduced in the use, and loop character is light modulation or straight-through, changes much in the use, can't determine, causes a lot of contradictions and accident.
(4) power loop may waste not and definitely.Because the power in each loop of electric power system is determined, but in actual use, the power in each loop of electric power system can't cover the light fixture actual power comprehensively, usually can run into the situation that actual power demand and loop setting power are not inconsistent, if actual power demand greater than the loop setting power, then can cause the power loop relative deficiency; If actual power demand, then can cause the part waste of part power loop less than the loop setting power.In actual the use, most lamp powers that each performance is used cause the wasting of resources far below power loop is installed.
(5) three-phase imbalance.Because lamp position in using, quantity randomness are very large, the good loop of planned balance is without in all senses.Field balancing is again because can't confirm that the phase place of each socket is difficult to realize in the use.So the lighting system three-phase imbalance is inevitable outcome.
(6) there is potential safety hazard in the electric power system unreasonable structure.On the one hand, electric power system is not to be dendritic, but is the plethora type, and more than 1,000 kilowatt three-phase electricity enters silicon control chamber, directly transfers the single-phase electricity in more than 1,000 loop to out.Three-phase imbalance, the variation of electricity consumption cause silicon control chamber and main line groove zone to have fire disaster hidden danger.On the other hand, loop quantity, position, specification and the character of existing professional light electric power system has all been installed in advance and has been fixed, adjust according to actual conditions if want, can only overlap long apart from temporary cable (guiding to the actual lamp position of using from light-adjusting cabinet), so both do not met the Electrical Safety standard, contradiction between temporary cable and the movable mechanism also may occur, and causes new potential safety hazard.
(7) wasting of resources, serious interference.As described in above-mentioned (1) to (4) point, the loop quantity of existing professional light electric power system, the position, specification and character have all been installed in advance and have been fixed, afterwards can't be according to all kinds, various scales are adjusted with light occasion or sight, do not reach instructions for use or the part resource is not utilized, cause a large amount of wastings of resources, for example a large amount of wastes of cable (large-scale arenas light cable copper consumption is above 25 tons), and these a large amount of cables, interference range is large, taking up room, (light main line recess gauge lattice surpass 1200*300 greatly, article 2), installation workload large (workload of light of stage engineering more than 90% laid cable).
Generally speaking, existing professional light electric power system is owing to adopting the loop power supply mode, each electricity consumption loop quantity, position, specification and character have all been installed in advance and have been fixed, can't carry out the adjustment of rational system according to actual conditions in actual use, produce thus the problems such as above-mentioned use is inconvenient, installation workload is large, serious waste of resources, violation Electrical Safety standard, hindered development and the application of light of stage.
Therefore, designing a kind of can the adjustment lamp bit quantity, character and specification according to the actual requirements, is technical barrier and realistic problems that professional performing art lighting technology field needs to be resolved hurrily to adapt to the different performing art light electric power systems that require with the light occasion.
