2 lighting power distribution system
2.1 for the set of lighting distribution transformers shall meet the following requirements:
An electrical equipment high-power impulse load, lighting and power should be shared transformer;
Power equipment and high-power impulse load, lighting should be with the impact load access from different transformers; If the conditions are not
Allows, need access to the same transformer, the lighting should be s pecial-fed wire and power supply;
Three lighting installation power, the lighting transformer.
2.2 emergency lighting power supply, according to the requirements of the emergency lighting category, place and the building power conditions, using the following
One of the ways:
A connected power grid independent of the normal lighting power supply line;
Two batteries, lamp comes with battery, battery installations focus on the set or partition set set;
3 emergency generating sets;
Four more than any two combination of methods.
2.3 evacuation lighting, exit signs lights and point marker lamps to use the battery power. Power security lighting and the places of power lines were received from different transformer or feeder trunk. Standby lighting power should be used in this chapter
2.2 listed in Part 1 or 3 ways.
2.4 Lighting distribution should adopt a combination of radial and trunk type system.
2.5 three-phase distribution main phase load should be balanced distribution of the maximum load should not exceed 115 percent of the average of the three-phase load,
The minimum load of not less than 85% of the average of the three-phase load.
2.6 Lighting distribution box should be set close to the center of the lighting load to facilitate the operation and maintenance of the position.
Single-phase branch circuit current of 2.7 for each lighting should not exceed 16A, then light the number should not be over 25; connected building group
Co-lamps, the loop current of not more than 25A, the number of lights should not be over 60; single-phase connection of high-intensity gas discharge lamp
Branch circuit current should not exceed 30A.
2.8 socket should not be connected in the same branch circuit and lights.
2.9 o f place in the larger voltage deviation, conditional, it is desirable to set the automatic voltage regulator device.
2.10 supply distribution lines of the gas discharge lamp should be set up in the lines or fixtures capacitor compensation, power factor should not be less than
0.9.
2.11 stroboscopic effect in the gas discharge lamp place to affect the visual task, using one of the following measures:
1 high-frequency electronic ballasts;
2 adjacent lamps tap in a different phase sequence.
2.12 when the class â… lamps, lamps exposed conductive parts should be reliable grounding.

28
2.13 safety extra low voltage power supply should be safety isolating transformer, the secondary side should not be done to protect ground.
2.14 residential buildings should be user set the power me ter; factory conditions should be according to the workshop to set the power meter; office building should be rented
Household
Or unit set the power meter.
2.15 distribution system grounding, protection of distribution lines shall comply with the relevant provisions of the current national standard.
Three conductor Select it
3.1 lighting distribution main and branch lines should be insulated copper wire or cable, the branch line section should not be less than 1.5mm2.
3.2 lighting load calculation on distribution lines should be current and light side to allow the voltage values ??to select the conductor cross-sectional area.
3.3 The main supply of gas discharge lamp of the three-phase distribution lines, which line section should meet the unbalanced current and harmonic current
Requirements, and should not be less than the phase line section.
3.4 The ground wire cross-section shall comply with the relevant provisions of the current national standard.
4 lighting control
4.1 public buildings and industrial buildings, corridors, stairwells, lobby and other public places, lighting, should adopt a centralized control, and
Partition group building conditions and natural lighting conditions to take control measures.
4.2 stadiums, theaters, lounges, waiting rooms and other public places should be centralized control, and need to take a dimmer or
Control measures to reduce illumination.
4.3 hostels (sets) rooms should be set energy-saving control switch.
4.4 Residential Buildings in the stairwell of the natural lighting, aisle lighting, in addition to the emergency lighting should be energy self-extinguishing switch.
4.5 Each lighting switches controlled by the number of lights should not be too much. The number of each room light switches should not be less than 2 (except as set only a light).
4.6 room or place equipped with two or more columns of lamps should be grouped according to the following controls:
A control lamp columns parallel with the side windows;
The two production sites according to the workshop, section, or processes;
3 Dianhuajiaoshi, conference rooms, function rooms, lecture halls and other places, close to or away from the podium grouping.4.7 Conditional place, should adopt the following control methods:
A place of natural light, the illumination of the place automatically switch lights or dimming;
2 personal use of the office, using the human body sensor or movement sensor automatically switch lights;
3 hotel foyer, elevator lobby and room layer corridor spaces, at night from time to time to reduce the automatic dimming of the illumination device;
