Design method of film, television and stage lamp power supply system

Abstract

The invention relates to a design method of a power supply system, in particular to a design method of a film, television and stage lamp power supply system. The design method comprises the following steps: step S10), dividing a light-required position of a light system into a plurality of power supply regions, and configurating regional distribution boxes with corresponding power; step S20), determining the standard of multi-core cables according to the regional distribution box with the maximum power supply power; step S30), determining the quantity, the power and the positions of socket modules connected with all the connection socket modules of each regional distribution box according to the utmost possible light quantity and the light power of each power supply region; and step S40), determining whether the socket modules are direct current socket modules or dimming socket modules according to the properties of the lights connected with the socket modules. The design mode breaks the limitation of the traditional thinking and can enable staff to adjust the quantity, the power and the positions of the lights according to the actual requirements in the mode of dispersing the regional power supply, so that the flexibility of the design and the installation of a light system can be greatly enhanced, and the project cost and the installation difficulty can be reduced.

Description

technical field [0001] The invention relates to a power supply system, in particular to a design method for 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 adjust some or even all of the lights. 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, whe...

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 loo
