第四章照度计算部分习题答案

4-7 如图4-21所示,某车间装有8只GC39型深照型灯具,内装400W 荧光高压汞灯,灯具的计算高度为10m ,光源光通量为20000lm ,灯具的光强分布如下表,维护系数为0.7。试求A 点的水平面照度。

表4-9 灯具的光强分布

由于E h1=E h2=E h7=E h8,E h3=E h4=E h5=E h6,故先计算E h1和E h3,然后求和E Ah 。 已知:计算高度h =10 m ,车间的维护系数由表4-1查得K =0.7 (1)光源1的水平照度E h1

光源1在水平面的投影点至计算点的距离d 1=9.6 m, 而光源1至计算点的距离l 1

由表4-9知:θ=40°时,I 40°=182 cd ,θ=45°时,I 45°=169 cd 直线内插法求得:θ=43.8°时,I θ1=I 43.8°=172.12 cd 则

(2)光源3的水平照度E h3

光源3在水平面的投影点至计算点的距离d 2=4.3 m, 而光源3至计算点的距离l 2

(3)8盏灯在A 点产生的实际照度E Ah

4-8.某精密装配车间长10m ,宽5.4m ,高3.5m ,有吊顶。采用YG701-3型嵌入式荧光灯具,布置成两条光带,如图4-22所示。试计算高度为0.8m 的水平面上A 点的直射照度。

解:按方位系数法计算A 点的水平照度E Ah

由题意知:精密装配车间采用了非连续布置的12盏YG701-3型嵌入式荧光灯具构成两条光带,灯具布置间距s =0.2 m ,而计算高度h =3.5-0.8=2.7 m ,光带的一端至计算点A 的投影距离d =1.35 m ,则垂直角θ

由于s <1/4cos θ,可将非连续布置灯具组成的光带按连续布置考虑,但在求光强或单位光强时需乘修正系数C 。

计算时可先计算一条光带在A 点产生的水平照度,然后求和。 (1)确定灯具光强分布类型

将灯具纵向垂直面光强I 0,α与I 0,0的比值I 0,α/ I 0,0绘制成曲线,与理论纵向平面光强分布曲线(图3-6)进行比较,可近似地认为YG701-3型荧光灯具属于C 类灯具。 (2)求方位角α和方位系数F x

由图知:光带长L =10-2×0.6=8.8 m ,光带一端至计算点A 的距离l

则,方位角α

查图4-12得水平方位系数:α=71°时,F x =0.66 (3)求单位光强I ’θ,0

由表4-2知:θ=25°时,I 25°=191 cd ,θ=30°时,I 30°=176 cd 直线内插法求得:θ=26.6°时,I θ=I 26.6°=186.2 cd 则,单位光强I ’θ,0

(4)确定维护系数K

对于精密装配车间,由表4-1查得K =0.8 (5)一条光带在A 点产生的水平照度E ’h

若采用T8型36W 高效荧光灯,按每支灯管的光通量为3350lm 计算,则

若采用T12型40W 荧光灯,按每支灯管的光通量为2200lm 计算,则

4-9.有一教室长11.3m ,宽6.4m ,高3.6m ,课桌高度为0.75m ,灯具离地高度为3.1m ,要求桌面平均照度为150lx ,室内顶棚、墙面均为大白粉刷,纵向外墙开窗面积占60%,纵向走廊侧开窗面积为10%,端墙不开窗;若采用YG2-1型灯具(附录4-3),请确定所需灯具数量,并画出灯具布置平面图。 解:采用利用系数法计算 由题意知:

顶棚空间高度h cc =3.6-3.1=0.5 m

室空间高度(计算高度)h rc =h =3.1-0.75=2.35 m 地板空间高度h fc =0.75 m 1.求室形指数RCR

2.求有效反射比

(1)顶棚有效反射比ρcc

顶棚、墙面均为大白粉刷,则取其反射比ρ=0.75

A S =0.5×2×(11.3+6.4)+11.3×6.4=90.02 m 2 A 0=11.3×6.4=72.32 m 2

取ρcc =70% (2)地板有效反射比ρfc

为了简化计算过程,取地板有效反射比ρfc =20% 3.求墙面平均反射比ρw

整个室空间墙壁的面积:A =2.35×2×(11.3+6.4)=83.19 m 2

整个室空间玻璃窗的面积:A g =2.35×11.3×60%+2.35×11.3×10%=18.59 m 2

4.确定利用系数U

由附录1-3知灯具的利用系数表中没有ρw =60%,为了保证照明质量,故按ρw =50%查表: 当RCR =2,ρcc =70%,ρw =60%,ρfc =20%时,U =0.79 当RCR =3,ρcc =70%,ρw =60%,ρfc =20%时,U =0.70 用直线内插法求得:

当RCR =2.88,ρcc =70%,ρw =60%,ρfc =20%时的利用系数U =0.78 5.确定维护系数K

由表4-1查得教室的维护系数K =0.8 6.求灯具数量N

若采用T8型36W 高效荧光灯具,按每支灯管的光通量为3350lm 计算,则

取N =11 盏,实际布灯时,考虑到灯具布置的对称性,选用12盏YG2-1型灯具作为教室的一般照明,选择2盏不对称配光的灯具作为黑板照明,其灯具布置平面图略。

4-11.某大进深办公室,长20m 、宽10m 、高2.75m ,顶棚反射比0.7、墙面反射比0.65、地面反射比0.275,窗总宽19m 、高1.7m ,采用嵌入顶棚式YG701-3型3管荧光灯具照明,每只灯管额定光通量是2200lm ,照度应满足国际标准的要求,试用单位容量法求所需的灯数。

解:用单位容量法计算

办公室面积:A =20×10=200 m 2 计算高度:h =2.75-0.75=2 m 设计照度:E av =300 lx

选用的YG701-3嵌入式荧光灯具符合CIE 规定的直接型灯具,且s ≤0.9h (1)求室空间系数RCR

(2)求单位电功率P 0

由表4-5知:RCR =1.67时,P 0=0.0424 W/m 2.lx

RCR =1.43时,P 0=0.0410 W/m 2.lx

(4)求灯具数量N

若电光源选用T8型32W 高效荧光灯,电子镇流器(忽略镇流器自身损耗),则灯具数量N

考虑到灯具布置,选取YG701-3型荧光灯具28盏。

第六章照明电气设计部分习题答案

9.试计算图6-21所示单相220V 供电的照明网络的电压损失。主干线AB 长80m ,截面为25mm 2;三个分支线BC 、BD 、BE 的截面均为4mm 2;照明负荷均为白炽灯,所有线

路均为铝芯导线。

图6-21 习题9附图

解:已知:l AB =80m ,l BC =30m ,l BD =15m ,l BE =20m ,s AB =25mm 2,s BC =s BD =s BE =4mm 2

对于单相220V 的供电网络,若采用铝芯导线,则C =7.45

由于照明负荷均为白炽灯,故线路的cos ?=1,可采用负荷距法计算电压损失: (1)AB 段线路的电压损失Δu AB %:

(2)BC 段线路的电压损失Δu BC %:

(3)BD 段线路的电压损失Δu BD %:

(5)线路末端的电压损失应为Δu AB %与BC 、BD 和BE 段中最大的电压损失Δu BC %之和:

10.已知一照明线路电压为220/380V ,全长90m 。现拟采用BLV-500(3×16+1×10)四根导线明敷,在距线路首端30m 处接有20kW 的电阻性负荷,在末端接有35kW 的电阻性负荷。试计算该线路的电压损失百分值。若负荷接线端允许电压损失为4%,试判断其是否符合要求?若不能满足要求,试按电压损失另选该线路导线的截面。 解:由题意画出线路示意图如下:

已知:该线路采用的是塑料绝缘铝芯导线,相线截面积为16mm 2,线路所接负荷均为电阻

性负载,即功率因数cos ?=1,由表6-4查得电压损失计算系数C =44.5,则该段线路末端的电压损失Δu %:

由计算结果知,线路的电压损失为5.3%,超过了负荷接线端允许的4%电压损失要求,需重新选择导线截面。

The formation and development of the Chinese calligraphy is closely related to the emergence and evolution of Chinese characters. In this long evolutionary process,Chinese characters have not only played an important role in exchanging ideas and transmitting culture but also developed into a unique art form.Calligraphic works well reflect calligraphers’ personal feeling, knowledge, self-cultivation, personality, and so forth, thus there is an e xpression that “seeing the calligraphers’ handwriting is like seeing the person”. As one of the treasures of Chinese culture, Chinese calligraphy shines splendidly in the world’s treasure house of culture and art.
