IEC 61034 Computer Controlled Wire and Cable Smoke Density Testing Equipment
Scope of application:
By determining the concentration of released smoke when cables and cables are burned under specific conditions, it is determined whether the cable or cable meets specific requirements.
Meet the standards:
Conforms to GB/T17651. January 2, 1998. IEC 61034-1-2, 1997 (Determination of smoke density of cables and cables under certain conditions).
The instrument involves mechanical, optical and electronic expertise in three aspects, is an optoelectronic integrated product, has the advantages of reasonable structure, stable performance, easy operation, etc.; WINDOWS XP operating interface, Visual Basic 6.0 style, perfect security mechanism. During the test period, the measurement results are displayed timely and the smoke density curve is dynamically drawn. The data can be saved permanently, viewed for printing or mail forwarding, and the report can also be printed directly.
Measurement principle:
1, light metering system
The smoke density optical measurement system for burning cables or optical cables under specific conditions consists of a light source, a silicon photocell receiver and a computer acquisition control system. The light beam generated by the light source passes through a 3m×3m×3m smoke density laboratory. A uniform aperture of 1.5m±0.1m in diameter is formed on the wall of the receiving surface of the light source. The silicon photocell is installed at the center of the aperture: when the combustion chamber is burned by cables or When a large amount of smoke is generated in the optical cable, the smoke particles will absorb the intensity of the light beam in the test chamber, so that the intensity of the light reaching the light receiving surface will be attenuated. At this time, the silicon photocell installed at the center of the aperture detects the light intensity of the light source and converts it into a voltage signal. Computer acquisition card for data conversion operations, and then output through the monitor.
2, computer control system
When the light source is subject to light, the light source is calibrated. When there is no burning material in the test chamber, and the light shield is not fully opened, the current light intensity is deemed to be the highest. At this time, the calibration light transmittance passes through the detection light attenuation of 100%; the shade plate is pulled down; The light that enters the photocell is completely blocked. At this time, the light transmittance of the calibration is 0%. After calibration, smoke is generated during the test and the light is attenuated. Then the data is input to the computer and the data can be processed by the computer. Relative to the initial 100% transmittance LTO with linear response
3, light source calibration
Light source calibration is the process of using the standard filter to simulate the actual light attenuation of the light measurement system for linearity correction process, generally use 25%, 50%, 75% of the standard filter for three penetrations and store the correction results Computer measurement system.
Technical parameters:
1, combustion chamber:
Internal size: 3Mx3Mx3M A total of 27 cubic meters can be a brick wall structure or a steel plate structure, which is selected by customers.
2, optical measuring device:
A. Imported quartz halogen lamp light source: nominal power: 100W, nominal voltage 12V, nominal luminous flux: 2000-3000Lm, nominal color temperature 2800-3200K.
B. Receiver: For silicon photovoltaic cells, light transmittance is 0% for no light, and 100% light transmission for light is completely blocked.
3, standard fire source:
A. Fire source is 1.0L alcohol (component 90%±1% ethanol + 496±1% methanol + 6%±1% water)
B. Alcohol tank: stainless steel, bottom: 210x110mm, top: 240x140mm, height 80mm
4, Smoke Mixing: Use a desktop fan to evenly distribute the smoke in the combustion chamber.
5, blank test: burning alcohol lamp to the combustion chamber temperature reached 25 ± 5 °C.
6, Temperature measuring device: The temperature sensor is installed at a distance of 15M from the wall within a distance of 0.5M from the wall inside the door.
7, with a set of transmittance measurement software, can output curves and reports.
8, including a computer
9, a laser printer
