Performance lamplight power supply system

Abstract

The invention relates to a power supply system, and particularly relates to a performance lamplight power supply system applicable to special light utilization fields such as a movie, a theatre a stage. The performance lamplight power supply system comprises a power supply distribution system and a plurality of area power distribution boxes; the power supply distribution system is used for receiving an external power supply and distributing the external power supply to the area power distribution boxes; each area power distribution box is used for supplying power supply to electric equipment in a pre-set power supply area; each area power distribution box is connected with a socket module group or a plurality of socket module groups; each socket module group comprises one or more than one socket module; and the area power distribution box is connected with the socket modules through a multi-core cable for transmitting three-phase alternating-current power, and the socket modules are connected through the multi-core cable for transmitting the three-phase alternating-current power. The limitation of the traditional thought is broken by using the system. An engineer can rapidly adjust the quantity, power and position of lamplight adjusting equipment according to actual demands by means of supplying power through diffused area power and placing diming control to a lamp position terminal, so that the design of the lamplight system and the installation sensitivity can be greatly improved, and the engineering cost and the installation difficulty can be reduced.

Description

technical field [0001] The invention relates to a power supply system, in particular to a lighting power supply system suitable for professional lighting occasions such as film and television, theaters, and stages. Background technique [0002] Based on the requirements of artistic effects, professional lighting systems such as film and television, theaters, and stages usually need to be adjusted partly or even completely. The power supply system of these professional lighting systems generally uses dimming cabinets for centralized dimming and power supply control. For example, for large-scale theaters (or studios), the number of dimming and through circuits can reach hundreds or even thousands of circuits. The power distribution equipment and dimming equipment (dimming cabinets) of these circuits are all installed in one Specially set room - silicon control room. The power supply department transmits all the electricity to the silicon control room, where it is distributed...

AI Technical Summary

Problems solved by technology

Therefore, the preset point cannot cover the actual application point, and cannot meet the actual circuit specification and property requirements, resulting in a series of problems:

Since the position of each circuit in the power supply system has been fixed, but the actual layout of the lighting position is flexible and changeable, this leads to: On the one hand, the position of the circuit in the power supply system cannot fully cover the actual circuit position, resulting in some locations that need electricity without electricity. , but some places that do not need electricity have the embarrassing situation of electricity, so that the number of circuits is relatively insufficient in actual use; on the other hand, not every performance needs to use all or most of the power supply system circuits. The number only accounts for 10%~20% of the total number of circuits in the power supply system, and the number of circuits is absolutely excessive, resulting in waste of cables and equipment resources

[0009] (2) The number of loops of various properties is relatively insufficient and absolute excess

Since the nature of each circuit in the power supply system (dimming or through) has been determined in advance, there may be situations where the number of dimming circuits (or through circuits) in the system does not match the number of dimming circuits (or through circuits) actually required, for example The number of dimming circuits preset by the system is less than the number of dimming circuits actually needed, or the number of straight-through circuits preset by the system is more than the number of straight-through circuits actually needed, resulting in insufficient or excess number of circuits of various properties

[0010] (3) Uncertainty in the nature of the loop

Due to a large number of automated lamps and new light source lamps being introduced into use, whether the nature of the loop is dimming or straight-through, there are many changes in use and cannot be determined, causing many contradictions and accidents

[0011] (4) Possibly insufficient loop power and absolute waste

Since the power of each loop of the power supply system has been determined, but in actual use, the power of each loop of the power supply system cannot fully cover the actual power of the lamp, and often encounter situations where the actual required power does not match the set power of the loop. If the required power is greater than the set power of the loop, the loop power will be relatively insufficient; if the actual required power is less than the set power of the loop, part of the loop power will be wasted

In actual use, the power of most lamps used in each performance is far lower than the power of the installation circuit, resulting in waste of resources

[0012] (5) Three-phase unbalance

[0013] (6) The structure of the power supply system is unreasonable and there are potential safety hazards

Unbalanced three phases and changes in power consumption cause major fire hazards in the silicon control room and the main trunking area

On the other hand, the number, location, specifications and nature of the circuits of the existing professional lighting power supply system have been installed and fixed in advance. If you want to adjust according to the actual situation, you can only connect long-distance temporary cables The location of the lamp), which does not comply with the safety regulations for electricity use, and may also cause conflicts between the temporary cable and the movable mechanism, resulting in new potential safety hazards

[0014] (7) Waste of resources and serious interference

As mentioned in points (1) to (4) above, the number, location, specifications and nature of the circuits of the existing professional lighting power supply system have been installed and fixed in advance, and it is impossible to use them according to various types and scales afterwards. Or scene adjustments, use requirements are not met or some resources are not used, resulting in a lot of waste of resources, such as a lot of waste of cables (large-scale theater lighting cables use more than 25 tons of copper), and these large numbers of cables, interference range Large, takes up a lot of space (the specification of the lighting main trunking exceeds 1200*300, 2 pieces), and the installation workload is large (more than 90% of the workload of the stage lighting project is on the laying of cables)

[0015] All in all, because the existing professional lighting power supply system adopts the loop power supply method, the number, location, specification and nature of each power consumption circuit have been installed and fixed in advance, and it is impossible to make reasonable system adjustments according to the actual situation in actual use, resulting in The above-mentioned problems such as inconvenient use, heavy installation workload, serious waste of resources, and violation of electricity safety regulations have hindered the development and application of stage lighting.
