ZY6166电线电缆烟密度试验机测试仪装置
Wire and cable smoke density tester tester device
1、符合标准:Conform to the standard:
GB/T17651.1～2-1998《电缆和光缆在特定条件下燃烧的烟密度测定》
GB/T17651.1 ~ 2-1998 "cable and optical fiber cable under certain conditions the burning smoke density
measurement,
2、适用范围:Scope of application:
用来测定电缆和光缆在特定条件下燃烧时释出烟的浓度
Used for determination of cable and cable released under certain conditions when burning smoke concentration
3、主要性能参数：The main performance parameters:
1、本仪器涉及机械、光学、电子三个方面的专业知识，是机光电一体化产品，具有结构合理、性能稳定、操作简便等优
点；WINDOWS XP操作界面、LabVIEW风格、完善的安全机制。测试期间实时显示测量结果并动态地绘出曲线，数据可以永
久保存、调阅和打印输出,可直接打印报表。
2、 电缆或光缆在特定条件下燃烧的烟密度光测系统由光源、硅光电池接受器和计算机系统组成。光源产生的光通过3m×
3m×3m的烟密度实验室，在光源对面的墙上形成一均匀光束，安装在光束中心处的光电池检测来自光源的光束强度。当燃烧室
内由于燃烧电缆或光缆产生大量烟雾时，烟把光电吸收掉一部分，达到硅光电池的光束强度就减弱，通过计算机系统对数据进
行处理，就能够计算出相对于初始时为的具有线性响应的透光率It。
3、光源：进口石英卤素灯，标称光返量：2000～3000Lm
4、接受器：光谱响应与照明委员长（CIE）的测光仪相匹配。
5、透光率0%为无光线通过，透光率光无遮挡完全通过。
6、标准火源：为1.0L酒精配置：乙醇90%、甲醇4%、水6%
7、利用台式风扇使烟在燃烧室里均匀分布。风扇转轴距离地面高度250mm,具墙500mm,风量7立方米每分钟。试验期间空气
由风扇作水平吹动。
1, it involves the mechanical, optical, electronic three aspects of professional knowledge, is a photoelectric
integration products, with reasonable structure, stable performance, easy operation, etc
Point; WINDOWS XP operating interface, LabVIEW style, perfect security mechanism. During testing real-time
display measurement results and dynamically draw perfect curve, the data can be everlasting
For a long time to save and read and print output, can be directly printed statements.
2, cable or optical cable under certain conditions of combustion smoke density optical measurement system
composed of light source, silicon photocell of receiver and the computer system. Light source of light by 3 m
x
3 m x 3 m smoke density lab, form a uniform light beam in the wall opposite the light source, the installation
of the photocell detection in the center of the beam intensity of light from a light source. When the
combustion chamber
Due to combustion within the cable or optical cable to produce a large amount of smoke, the smoke of
photoelectric absorption, achieve the silicon photocell beam intensity is abate, through the data into the
computer system
Line processing, will be able to calculate the relative to the initial with linear response light
transmittance of It.
3, light source: imported quartz halogen lamp, nominal return amount of light: 2000 ~ 3000 lm
4, receiver: chairman of the spectral response and international lighting (CIE) match the photometer.
5, 0% light transmittance through light, light transmittance light shining through.
6, standard fire: 1.0 L configuration: alcohol 90%, water 6% 90% ethanol, methanol
7, use desktop fan to make smoke uniform distribution in the combustion chamber. Fan shaft height distance 250
mm, 500 mm wall, air volume 7 cubic meters per minute. During the test air
Level blown by the fan.
