Takardun Tashin Tsari na Zafi

Wani takar tashin tsari da zafi don hakan samun cewa tsarin da zafin kable mai sarki suna da sassan da ke gaba.

Akwai Da Yake Zaka Don Takar Tashin Tsari na Kable Mai Sarki

Wannan shi ne wani yanayi na kimiyya kuma kwaikwayen da za suka yi a wannan takarta suna da kyau. Ana bukata a kunna, micrometer gauge da yake iya kimiyya karshen da ke da farkon 0.01 mm, vernier caliper wanda yake iya karanta da kyau babu karshen da ke da farkon 0.01 mm, measuring microscope ta da magnification da ba tare da 7 times kuma yana iya karanta da kyau babu karshen da ke da farkon 0.01 mm, da graduated magnifying glass wanda yake iya karanta da kyau babu karshen da ke da farkon 0.01 mm.

Kafin hada, ake gina abubuwan da za su gine don kimiyyoyi da ingantattun kimiyya. An fi sune abubuwan da biyu: kable core pieces da slice pieces.

Giniyar Abubuwan

Abubuwan suka ji daga kable da ake gina su don ingantattun kimiyya.

Tarhin Takar Tashin Tsari na Kable Mai Sarki

Yi amfani da abubuwan da ke da tsari da 300 mm masu kula da kula da kable da zafi. Ji abubuwan daga kabilu na gaba da ake cika da ake gina duk fadada baya ba a tabashe tsarin ko zafi. Yi amfani da slice pieces don kimiyyoyi optikal, idan an bukata a ji fadada baya da kusa. Ji slices da kasa da kasa a kasa na kable axis. A yanzu mai kimiyya mafi yawa a yi kimiyyar core da insulated core diameters da micrometer gauge ko vernier caliper, da kasa na kable axis.

Yi kimiyya a tara da tsawo uku a kan abubuwan, kusan 75 mm bayan 300 mm piece. Yi kimiyya na inner da outer diameters na insulation ko zafi a har da wurin. Don inganci, yi kimiyya biyu a har da wurin, to goma kimiyyoyi 6 don inner da outer diameters. Fara kimiyyar average outer diameter da inner diameter daga waɗannan kimiyyoyi. Tashin radial average na insulation ko zafi shine farkon kimiyyar average outer da inner diameters, ya kadan da biyu.

Idan a tabbas tushen a yi kimiyya, yi amfani da rukunin optikal da a ji slice section daga abubuwan.

A halin sliced section, abubuwan ana ji a measuring microscope along the optical axis. Don circular specimen, ana yi 6 kimiyyoyi a kan periphery a tara da tsawo uku. Don noncircular conductor, ana yi kimiyya radially a har da wurin inda tashin insulation yana aiki da kasa. Jumlah slices suka ji daga abubuwan a tara da tsawo uku a kan tsari a kan abubuwan haka cewa jami'an waɗannan kimiyyoyi ba za su ci 18. Misali, a halin circular conductor, ana ji 3 slices daga abubuwan da ake yi 6 kimiyyoyi a kan har slice. A halin noncircular conductor, jumla slices suka ji daga abubuwan ta yi amfani da jumla points of minimum thickness of insulation. Idan a nan kimiyya ana yi a kan points of minimum thickness ba kawai.

Mahimmancin Tsarin Kable

Yana da mahimmanci a kan kable don yin da ita ce da kula da mechanical stresses a lokacin da ita ke yi shekaru.

Lissafin Tashin Tsari

Don Core/Cable Piece

Inda, D_out shine average of six measurements taken for outer diameter of the insulation/sheath. Inda, Din shine average of six measurements taken for inner diameter of the insulation/sheath.

Don Slice Piece – The average of 18 optical measurements is taken as the minimum thickness of insulation/sheath.
