Bayyana Dadi na Kafin Jirgin Kabeli na Noma

Wani yanzu ya kula da kayan aiki don tabbatar da inganci da kafin rukunin cable ta ikkar zafi. Ana bayar da inganci masu daidai a cikin kafin rukunin cable ta ikkar zafi don tabbatar da an iya taimakawa wajen samar da gaskiya da dacewa a kan ido na cable a lokacin da yake amfani. Yana bukata a yi bincike wannan inganci domin tabbatar da shi ya zama kamar yadda aka nuna. Wannan abubuwan inganci sun taimaka wajen ba da dacewa da amaninsa ga cable.

Abubuwan Kayan Aiki Don Bincike Ingantaccen Kafin Rukunin Cable ta Ikkar Zafi

A nan yana nufin da ita ce a zaba abubuwan kayan aiki masu daidai. Ya kamata a canza micrometer gauge na iya bincika babban 0.01 mm, vernier caliper na iya karanta babban 0.01 mm, measuring microscope na linear magnification da take da 7 karamin kowane, da kuma graduated magnifying glass na iya karanta babban 0.01 mm.

Kafin bincike, ana fara da hanyoyi 2: 1) hanyoyi na core cable, 2) hanyoyi na slice pieces.

Tsarin Bincike Ingantaccen Kafin Rukunin Cable ta Ikkar Zafi

Ana fara da hanyoyi na core ko cable da take da 300 mm da za su cutta daga sabon kirkiro. Hanyoyin ya kamata a cutta daga sabon kirkiro, kuma a duba duk abubuwan da ke cikin kafin rukuni ko sheath bayan a cutta hanyoyin. Ana cutta slice pieces daga cable don optical measurement. A nan, za a iya duba abubuwan da ke cikin kafin rukuni ko sheath idan yana bukata. Slice ya cuta a kadan mai tsawo na cable. Binciken ya kamata a yi a faren yamma. Ana yi bincike diameter na core na cable, diameter na insulated core, cable da insulation, da kuma sheath, a kan micrometer gauge ko vernier caliper. Binciken ya kamata a yi perpendicular zuwa axis na core ko cable.

Ana yi bincike a 3 wurare na mafi girma a kan hanyoyi. Wurare ake yi a 75 mm a kan 300 mm na hanyoyi. Ana yi bincike diameter na inside da outside na kafin rukuni ko sheath. A kowane wurar, ana yi 2 binciken don inganta dacewa. Saboda haka, ana yi 6 binciken don diameter na inside da outside na kafin rukuni/sheath. A yi average ta 6 binciken na outer diameter, ana samu average measured outer diameter na insulation/sheath. Daga baya, a yi average ta 6 binciken na inner diameter, ana samu average measured inner diameter na insulation/sheath. Yanayin average outer da inner diameter divided by two shine average radial thickness na insulation/sheath.

Idan visual examination na hanyoyi ya bincike eccentricity, ya kamata a yi optical method a kan slice section na hanyoyi.
A nan, hanyoyin ya kamata a yi a kan measuring microscope along the optical axis. A kan circular specimen, ana yi 6 binciken along the periphery at a regular interval. A nan noncircular conductor, ana yi binciken radially a kowane wurar da inganci na insulation ya shafi minima. Za a cuta slices kadan kadan daga hanyoyi a fadada, hakan don a yi total of not less than 18 measurements. Misali, a nan circular conductor, za a cuta 3 slices kadan kadan, da kuma 6 binciken a kan kowane slice. A nan noncircular conductor, number of slices taken from a specimen depends upon the number of points of minimum thickness of insulation. Idan haka, ana yi binciken kawai a kowane wurar da inganci na insulation ya shafi minima.
