Specific embodiment

Embodiment one

The present embodiment provides a kind of for stage, the light electric power system of video display, and the light electric power system includes：Power supply is matched somebody with somebody Electric system 90 and several region distribution boxs, the source power distribution system 90 are used to receive external power source and distribute to described in each Region distribution box, each region distribution box is used to provide power supply for the electrical equipment of predetermined power supply area, and each region is matched somebody with somebody Electronic box is connected with an at least jack system, and each jack system includes the power supply module 20 of one or more series connection, wherein institute State and connected by the second multicore cable 70 between power supply module 20.

As shown in figure 22, the source power distribution system 90 of the system draws 8 tunnel power distributions to 8 region distribution boxs.It is located at 4 region distribution boxs 21,22,23,24 of top be located at fixed light region, underlying 4 region distribution boxs 25,26, 27th, 28 it is located at mobile light region.

Jack system is described in detail by as a example by fixed light region, as shown in figure 22, first region distribution Case 21 is connected with a jack system, and the jack system includes 4 power supply modules 20 of series connection；Two Areas distribution box 22 connects A jack system is connected to, the jack system includes 4 power supply modules 20 of series connection；3rd distribution box of region 23 is connected with one Individual jack system, the jack system includes 6 power supply modules 20 of series connection；4th region distribution box is connected with a socket system System, the jack system equally includes 6 power supply modules 20 of series connection.

It will be appreciated by persons skilled in the art that above-mentioned regional distribution box can connect a jack system, Each power supply module power requirements that can be connected in multiple jack systems, and each jack system can be with identical, it is also possible to no Together, as long as the design maximum work(of the power sum no more than the region distribution box of the full socket system that region distribution box is connected Rate.

Traditional light of stage electric power system uses single-phase loop power supply, just switchs to from mouth under the light-adjusting cabinet of silicon control room Three road electricity are sent to terminal, it is necessary to press phase line, zero line, ground wire power transmission by single-phase loop, need to use 9 core electric wires；And use this implementation The light electric power system of example uses area power and powers, and three-phase electricity first is sent into terminal reallocation, three tunnels of same power Electricity only needs 5 core cables to terminal（A、B、C、N、Pe）.It is only equivalent to the 5/9=55.6% cable consumptions of single phase power supply.

The current supply circuit quantity of traditional light electric power system is laid according to maximum quantity, and cable consumption is very big.Such as Guangzhou grand theater hall uses 1512 loops, Grand National Theatre theatre using more than 2000 loops, and it is actually used at most No more than 400 loops, typically in 100 to 200 loops.It is big with Guangzhou grand theater according to the light electric power system of the present embodiment As a example by the scale of the Room and Grand National Theatre theatre, calculated with terminal current supply circuit, no more than 400（Can be limited by with easily extension Region maximum electric power）, the ratio of cable consumption and original system is 400/1512=26.5%（Guangzhou grand theater pattern）, 400/2000=20%（Grand National Theatre pattern）, due to reducing a large amount of fixed loops, reduce a large amount of unnecessary cable pavings If wasting.

Due to the characteristic of video stage light light, its lighting time mostly be with minute, second calculate, but be not excluded for some Under extremity, indivedual light fixtures are lighted for a long time, and the light fixture that can not exclude these long-term electricity is large-power lamp, but its Position cannot determine, in order to tackle these individual cases, in traditional loop power supply, the service cable in all loops will be by Long-term safety current-carrying considers that i.e. cross-section of cable product is sufficiently large.And the present embodiment is powered using area power, the electricity in region Amount is calculated in tens kilowatts of rank, is usually more than ten, or even tens lamp services, indivedual several long-term electricity Amount, does not result in long-term high current load, and theoretically, block supply cable can be by the 30% of maximum output power consideration Can（Because the probability that the light fixture in a region is lighted is very low simultaneously, typically also with regard to 2,3 times, and the time is very short, more more than ten Second to the rank of tens seconds）.

Using the light electric power system of the present embodiment, by taking the grand theater of Guangzhou as an example, cable is powered mould relative to conventional circuit Formula can just save=(1-55.6% × 26.5% × 30%)=95.6%.Even if not considering the saving of block supply cable 30%, cable =(1-55.6% × 26.5%)=85.3% can also be saved.
