ZY6166電線電纜煙密度試驗機測試儀裝置
Wire and cable smoke density tester tester device
1、符合標準:Conform to the standard:
GB/T17651.1~2-1998《電纜和光纜在特定條件下燃燒的煙密度測定》
GB/T17651.1 ~ 2-1998 "cable and optical fiber cable under certain conditions the burning smoke density
measurement,
2、適用范圍:Scope of application:
用來測定電纜和光纜在特定條件下燃燒時釋出煙的濃度
Used for determination of cable and cable released under certain conditions when burning smoke concentration
3、主要性能參數:The main performance parameters:
1、本儀器涉及機械、光學、電子三個方面的專業知識,是機光電一體化產品,具有結構合理、性能穩定、操作簡便等優
點;WINDOWS XP操作界面、LabVIEW風格、完善的安全機制。測試期間實時顯示測量結果并動態地繪出曲線,數據可以永
久保存、調閱和打印輸出,可直接打印報表。
2、 電纜或光纜在特定條件下燃燒的煙密度光測系統由光源、硅光電池接受器和計算機系統組成。光源產生的光通過3m×
3m×3m的煙密度實驗室,在光源對面的墻上形成一均勻光束,安裝在光束中心處的光電池檢測來自光源的光束強度。當燃燒室
內由于燃燒電纜或光纜產生大量煙霧時,煙把光電吸收掉一部分,達到硅光電池的光束強度就減弱,通過計算機系統對數據進
行處理,就能夠計算出相對于初始時為的具有線性響應的透光率It。
3、光源:進口石英鹵素燈,標稱光返量:2000~3000Lm
4、接受器:光譜響應與照明委員長(CIE)的測光儀相匹配。
5、透光率0%為無光線通過,透光率光無遮擋完全通過。
6、標準火源:為1.0L酒精配置:乙醇90%、甲醇4%、水6%
7、利用臺式風扇使煙在燃燒室里均勻分布。風扇轉軸距離地面高度250mm,具墻500mm,風量7立方米每分鐘。試驗期間空氣
由風扇作水平吹動。
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.
