Umaleko wokukhusela isinyithi lulwakhiwo oluyimfuneko kakhuluiintambo zombane ezifakwe i-polyethylene ezidityaniswe nge-medium-voltage(3.6/6kV∽26/35kV)Ukuyila ngokuchanekileyo ulwakhiwo lwekhaka lesinyithi, ukubala ngokuchanekileyo umbane we-short-circuit eza kuthwalwa likhaka, kunye nokuphuhlisa indlela efanelekileyo yokucubungula ikhaka kubalulekile ukuqinisekisa umgangatho weentambo ezidityanisiweyo kunye nokhuseleko lwenkqubo yonke yokusebenza.
Inkqubo yokukhusela:
Inkqubo yokukhusela kwimveliso yeentambo ze-medium-voltage ilula kakhulu. Nangona kunjalo, ukuba ingqalelo ayinikwanga kwiinkcukacha ezithile, inokukhokelela kwimiphumo emibi kumgangatho weentambo.
1. Iteyiphu yobheduInkqubo yokukhusela:
Iteyiphu yobhedu esetyenziselwa ukuzikhusela kufuneka ibe yiteyiphu yobhedu ethambileyo efakwe ngokupheleleyo ngaphandle kweziphene ezifana nemiphetho egobileyo okanye imifantu kumacala omabini.Iteyiphu yobheduoko kunzima kakhulu kunokonakalisaumaleko ohambisa i-semiconductor, ngelixa iteyipu ethambileyo kakhulu inokushwabana lula. Ngexesha lokusonga, kubalulekile ukuseta i-engile yokusonga ngokuchanekileyo, ukulawula uxinzelelo ngokufanelekileyo ukuze kuthintelwe ukuqina kakhulu. Xa iintambo zinamandla, ubushushu buvelisa ubushushu kwaye buyanda kancinci. Ukuba iteyipu yobhedu isongiwe ngokuqinileyo kakhulu, inokungenela kwisikhuselo sokukhusela okanye ibangele ukuba iteyipu iqhekeke. Izinto ezithambileyo kufuneka zisetyenziswe njengephedi kumacala omabini ereyile yokuthatha yomatshini wokukhusela ukuthintela nawuphi na umonakalo onokwenzeka kwiteyipu yobhedu ngexesha lamanyathelo alandelayo kwinkqubo. Izihlanganisi zeteyipu yobhedu kufuneka zifakwe i-spot-welded, zingabi yi-soldered, kwaye ngokuqinisekileyo zingadibani kusetyenziswa iiplagi, iiteyipu zokuncamathelisa, okanye ezinye iindlela ezingezizo ezisemgangathweni.
Kwimeko yokukhusela iteyiphu yobhedu, ukudibana nomaleko we-semiconductive kunokubangela ukwakheka kwe-oxide ngenxa yomphezulu woqhagamshelwano, ukunciphisa uxinzelelo loqhagamshelwano kunye nokumelana kabini koqhagamshelwano xa umaleko wokhuselo lwesinyithi udlula kubushushu okanye ukuncipha kunye nokugoba. Ukudibana okubi kunye nokwanda kobushushu kunokukhokelela kumonakalo othe ngqo kwingaphandle.umaleko ohambisa i-semiconductor. Ukudibana ngokufanelekileyo phakathi kweteyiphu yobhedu kunye nomaleko we-semiconductive kubalulekile ukuqinisekisa ukusethwa ngokufanelekileyo. Ukufudumala okugqithisileyo, ngenxa yokwanda kobushushu, kunokubangela ukuba iteyiphu yobhedu yande kwaye iguquguquke, yonakalise umaleko we-semiconductive. Kwiimeko ezinjalo, iteyiphu yobhedu eqhagamshelwe kakubi okanye engadityaniswanga kakuhle inokuthwala umsinga wokutshaja ukusuka kwisiphelo esingasethwanga ukuya kwisiphelo esisethwanga, nto leyo ekhokelela ekutshiseni kakhulu nasekugugeni ngokukhawuleza komaleko we-semiconductive kwindawo yokuqhekeka kweteyiphu yobhedu.
2. Inkqubo yokukhusela ucingo lwekopolo:
Xa usebenzisa isikhuselo sentambo yobhedu esinamaqhuqhuva, ukusonga iingcingo zobhedu ngqo kumphezulu wesikhuselo sangaphandle kunokubangela ukugquma okuqinileyo, okunokonakalisa ubushushu kwaye kukhokelela ekuqhekekeni kweentambo. Ukujongana noku, kuyimfuneko ukongeza iileya ezi-1-2 zeteyiphu ye-nylon ejikelezayo kumaleko wesikhuselo sangaphandle esinamaqhuqhuva emva kokukhupha.
Iintambo ezisebenzisa ukhuselo lwentambo yobhedu oluneziphene ezikhululekileyo azinangxaki yokwakheka kwe-oxide efumaneka phakathi kweengqimba zeteyiphu yobhedu. Ukhuselo lwentambo yobhedu alugobi kangako, alunazo iinguqu ezininzi zobushushu, kwaye alunazo iinguqu ezininzi zokumelana noqhagamshelwano, zonke ezi zinto zinegalelo ekuphuculweni kokusebenza kombane, koomatshini, nakubushushu ekusebenzeni kweentambo.
