Description
Technical field
The present invention relates to electric power system, specifically is a kind of light electric power system that is applicable to specialties such as video display, arenas, stage with the light occasion.
Background technology
Based on the requirement of artistic effect, professional lighting such as video display, arenas, stage system need adjust part even whole light usually.The electric power system of these professional lighting systems, the light modulation and power supply control of generally adopting 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 light modulation equipment (being light-adjusting cabinet) all install concentratedly one special be provided with the room---the silicon control is indoor.Power supply department is delivered to silicon control chamber to whole electric weight, carries out distribution, adjustment, the control of electric weight then 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 gets into 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 through cable 9; Each power distribution cabinet 3 is distributed to several light-adjusting cabinets 4 to electricity through cable 9 again, and each light-adjusting cabinet 4 then distribution member through inside 13 converts three-phase electricity into single-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.
Be provided with two light modulation modules with each light-adjusting cabinet below and two straight-through modules are that example describes; Specifically be the first light modulation module 16 and the first straight-through module 18 that each light-adjusting cabinet all is provided with power less (for example 2-3kW), and power the second light modulation module 17 of big (for example 5-6kW) lead directly to module 19 with second.Wherein, light modulation, straight-through less first socket 7 (for example 16A) of module 16,18 corresponding rated current that rated power is less, the light modulation that rated power is bigger, straight-through bigger second socket 8 (for example 32A) of module 17,19 then corresponding rated current.
For face light, slap on the face, post light, ground flow, fixed position such as back-up circuit, the lower-powered first light modulation module 16 and first leads directly to module 18 and directly passes through 3X4mm
2The 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 bigger and the second straight-through module 19 directly pass through 3X6mm
2The cable 11 of specification (it is 39A that the copper core allows the long-term work electric current) connects the second bigger socket 8 of rated current.
For shift positions such as top light, sidelights, each light modulation, straight circuit are connected to respective socket through grid top terminals case 5 on the grid top and the bar upper terminal case 6 on the suspension rod successively indirectly.Wherein, is connected through multicore row's cable or circle cable 12 between grid top terminals case 5 and the bar upper terminal case 6, in addition, it is 3X4mm that the lower-powered first light modulation module 16 and first leads directly to module 18 employing specifications
2Cable 10 as connecting line (connecing first socket 7), it is 3X6mm that the second light modulation module 17 that power is bigger and the second straight-through module 19 adopt specifications
2Cable 11 as connecting line (connecing second socket 8).
What yet above-mentioned professional light electric power system adopted in essence is the loop power supply mode; Quantity, specification, character (light modulation or straight-through) as far back as silicon control chamber just has been assigned as final use loop to incoming power are all confirmed; Carry out the electric power system wiring then in view of the above; The back can only be finely tuned electric power system, is difficult to carry out big adjustment.But lighting art does not have 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 is with 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, causes part to need the position of electricity consumption not have; And there is the awkward situation of electricity the position that part need not electricity consumption, to such an extent as to loop quantity relative deficiency during actual the use; On the other hand, not that each performance all need be used 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 is with absolute superfluous.Because the character in each loop of electric power system (light modulation is still straight-through) is confirmed 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 confirm, causes a lot of contradictions and accident.
(4) power loop maybe not enough and absolute waste.Because the power in each loop of electric power system is confirmed; 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 big, the loop that planned balance is good does not have 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 an 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 the branch type, but is the plethora type, and more than 1,000 kilowatt three-phase electricity gets into silicon control chamber, and the single-phase electricity that directly transfers more than 1,000 loop to is come 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 all install and fix in advance; If want to adjust according to actual conditions, can only overlap length apart from temporary cable, so both do not met the Electrical Safety standard; Contradiction between temporary cable and the movable mechanism also possibly take place, and causes new potential safety hazard.
(7) wasting of resources, serious interference.Of above-mentioned (1) to (4) point, loop quantity, position, specification and the character of existing professional light electric power system have have all installed and fixed in advance, can't adjust with light occasion or sight according to all kinds, various scale afterwards; 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 big; Take up room big (light main line recess gauge lattice surpass 1200*300,2) installation workload big (workload of light of stage engineering more than 90% laid cable).
Generally speaking; Existing professional light electric power system is owing to adopt the loop power supply mode; Each electricity consumption loop quantity, position, specification and character all install and fix in advance; Can't carry out the adjustment of rational system according to actual conditions in actual use, produce problems such as above-mentioned use is inconvenient, installation workload is big, serious waste of resources, violation Electrical Safety standard thus, hinder the 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 video display, light of stage technical field need to be resolved hurrily to adapt to different video display, the light of stage electric power systems that require with the light occasion.
