Hlau thiab Cable Smoke Density Test Tshuab

Ua raws li GB / T17651.1 ~ 2, IEC61034-1 ~ 2. Kev txiav txim siab ntawm cov pa luam yeeb ntom ntom yog ib qho tseem ceeb ntawm kev ntsuas cov yam ntxwv ntawm kev kub hnyiab ntawm cov kab hluav taws xob lossis cov khoom siv kho qhov muag, uas cuam tshuam nrog kev khiav tawm ntawm cov neeg ua haujlwm thiab kev muaj peev xwm mus rau qhov kev txiav txim siab ntawm kev tua hluav taws.Qhov ntsuas no tsuas yog siv los txiav txim siab cov pa taws. tso tawm thaum lub cable thiab optical cable raug hlawv nyob rau hauv tej yam kev mob, thiab xyuas qhov ceev ntawm cov pa luam yeeb tsim. Nyob rau hauv cov nplaim taws kub hnyiab los yog tsis muaj qhov kub hnyiab, lub teeb xa hluav taws xob yog siv los ua ib txoj hauv kev los sib piv cov cables sib txawv lossis cov khoom siv kho qhov muag hauv cov xwm txheej tshwj xeeb.

Cov cuab yeej no suav nrog kev paub txog kev paub txog peb yam ntawm cov tshuab, optics, thiab hluav taws xob. Nws yog cov khoom siv hluav taws xob sib xyaw ua ke nrog cov qauv tsim nyog, kev ua haujlwm ruaj khov, thiab ua haujlwm yooj yim. WINDOWS 10 kev khiav hauj lwm interface, LabVIEW style, thiab zoo meej kev ruaj ntseg mechanism. Thaum lub sij hawm qhov kev xeem, qhov ntsuas tau tshwm sim nyob rau hauv lub sij hawm ntawm lub sij hawm thiab lub zoo meej nkhaus yog dynamically kos (tso tawm lub transmittance thiab lub sij hawm nkhaus). Cov ntaub ntawv tuaj yeem khaws cia mus tas li, nyeem thiab luam tawm, thiab daim ntawv tshaj tawm tuaj yeem luam tawm ncaj qha.

The smoke density optical measurement system of the cable or optical cable burning under specific conditions is composed of a light source, a silicon photocell, a light source receiver and a computer system.The light generated by the light source passes through the smoke density laboratory of 3 × 3 × 3(m) to form a uniform beam with a diameter of 1.5m±0.1m on the wall opposite the light source. The photocell installed at the center of the beam detects the intensity of the beam from the light source. When a large amount of smoke is generated in the combustion chamber due to burning cables or optical cables, the smoke absorbs a part of the photoelectricity, and the intensity of the beam reaching the silicon photovoltaic cell is weakened. By processing the data through the computer system, it can be calculated that it is 100% relative to the initial Linear response light transmittance.

Tag nrho cov cuab yeej muaj xws li kaw kaw chamber, photometric ntsuas system, cawv tais, combustion system, igniter, kuaj lub thawv, cable tuav, ntsuas kub ntsuas thiab pa luam yeeb ntom ntom software. Lub Circuit Court yog tsim los ntawm ib qho nti microcomputer, nrog cov ntsiab lus siab thiab kev ua haujlwm ruaj khov. Cov cuab yeej no yog tsim rau tag nrho cov cables thiab yog dav siv los ntawm cov chaw tsim khoom ntawm cov hlau thiab cable kev lag luam nrog rau kev tshawb fawb thiab kev soj ntsuam cov tuam tsev. Lub thawv ntsuas yog lub ntsuas ntsuas nrog qhov ntim ntawm 27m³.
