Yini Inkokhiso-Isisetshenziswa Sokuhlola Sokukhipha?

Shaja{0}}khulula okokusebenza kokuhlola ukusebenza

Ukuhlola ukusebenza kokushajwa kwebhethri{0}}ukuhlolwa kokusebenza okuyisisekelo, ngokuvamile okuhlanganisa inkokhiso-yeyunithi yokukhipha kanye neyunithi yohlelo lokulawula. Ingakwazi ukulawula ukude ibhethri lamandla ngekhompyutha ukuze ikhiphe-i-voltage, engaguquki-yamanje, noma ishaja esethiwe ijika lamandla{5}}esimisiwe. Ngezinzwa zikagesi, zamanje, nezinga lokushisa, amapharamitha ahambisanayo angalinganiswa, futhi nemingcele yokuhlola njengomthamo webhethri lamandla, amandla, nokuvumelana kwephakethe lebhethri kungatholwa.

Izinto zokuhlola ngokuvamile zihlukaniswa ngokwamazinga amandla kanye namandla kagesi ukuze kuhlangatshezwane nezidingo zokuhlola ukusebenza kwamabhethri wamandla namaphakethe ebhethri anezilinganiso ezahlukene zamandla kagesi namandla. Isibonelo, okokusebenza okuvamile kokuhlola ibhethri yeselula eyodwa-imvamisa ikhetha ububanzi bevolthi esebenzayo engu-0–5 V kanye nebanga lamanje elisebenzayo elingu-0–100 A, elingahlangabezana nezimfuneko eziyisisekelo zokuhlola ukusebenza kwezinhlobo eziningi zamabhethri anamandla emoto. Ngokuhlolwa kokusebenza okuyisisekelo-kwamaphakethe ebhethri anamandla aphezulu, ububanzi be-voltage kudingeka bukhethwe ngokuya ngebanga le-voltage yephakethe lebhethri; imishini yokuhlola ejwayelekile esetshenziswa jikelele idinga i-0–500 V enamandla omkhawulo ongaphezulu ka-150–200 kW.

Umfanekiso 6-7 ubonisa isistimu yokuhlola ibhethri ye-Arbin eminingi-eyakhiwe inkampani ethile, engabeka amasu ahlukene okushaja{3}}ngokusebenzisa isofthiwe yokuhlela futhi irekhode ngesikhathi sangempela amandla kagesi, amandla amanje, okukhipha amandla, amandla, kanye nezinga lokushisa elingaphezulu lebhethri elihlolwayo.

Imishini yokuhlola ukumelana nangaphakathi

Ukumelana nebhethri kwangaphakathi, njengepharamitha yokulinganisa eyinhloko, ingahlolwa ngezindlela ezifaka isikwele-indlela yamanje yegagasi, indlela yebhuloho le-AC, indlela ye-AC impedance, indlela ye-DC volt-indlela ye-ampere, indlela{2}}yesiyingi emfushane, nendlela yamanje ye-pulse. Indlela yokukhishwa kwe-DC ilula futhi ivame ukusetshenziswa emisebenzini yobunjiniyela. Le ndlela isebenzisa ugesi omkhulu osheshayo (ngokuvamile amashumi amaningana kuya kwangaphezu kwekhulu ama-ampere) ebhethrini, ikala ukwehla kwamandla kagesi ngokushesha ebhethrini, futhi ibala ukumelana kwangaphakathi kusetshenziswa umthetho we-Ohm. Indlela ye-AC ijova isignali yamanje ye-AC ephansi-yefrikhwensi yamanje ye-AC kubhethri futhi ikala umehluko wesigaba phakathi kwevoltheji ephansi-yefrikhwensi nephansi{8}}imvamisa yamanje kumatheminali ebhethri ukuze kubalwe ukumelana kwangaphakathi. Imishini eminingi yokuhlola ukumelana nangaphakathi okwamanje ekhiqizwa abakhiqizi isebenzisa indlela ye-AC yokuhlola ibhethri. Amanani 6-8 kanye no-6-13 abonisa abahloli abajwayelekile bangaphakathi bokumelana nemingcele yabo.

Ithebula 6-13 Amapharamitha womhloli wangaphakathi wokumelana

Imishini yokulinganisa izinga lokushisa

Ukunyuka kwezinga lokushisa kwebhethri ngesikhathi sokushajwa-izinqubo zokuyikhipha kungenye yezimiso ezibalulekile. Nokho, ukuhlola okuvamile kungakala kuphela amapharamitha wokuma ajwayelekile kugobolondo lebhethri. Ngokuvamile, ukushaja{3}} okokusebenza kokukhipha kufakwe isistimu yokutholwa kwezinga lokushisa elihambisanayo elinomsebenzi wokuvumelanisa idatha yezinga lokushisa ngesikhathi sokushaja{4}}inqubo yokukhipha. Ngaphezu kwalokho, okokusebenza okuchwepheshile kokuhlola izinga lokushisa kuhlanganisa{6}}ama-thermometer angaxhunywanga namakhamera wokuthwebula we-thermal. Ikhamera yesithombe esishisayo ingaqoqa umlando wokuhluka kwezinga lokushisa wendawo eyodwa noma ngaphezulu yebhethri futhi ikhiphe idatha yokuhluka kwezinga lokushisa yamaphoyinti ajwayelekile okulinganisa, iyenze idivayisi yokulinganisa echwepheshile yokuhlaziya inkambu yezinga lokushisa kwebhethri. Ithemometha{9}}okungaxhunywanwa naye kanye nekhamera yokuthwebula eshisayo iboniswa kuMfanekiso 6-9 kanye noMfanekiso 6-10, ngokulandelana.
