Esifundweni se-physics siyazi ukuthi injini kagesi ingasebenza futhi njengejeneretha; lo mphumela usetshenziselwa ukubuyisela ugesi. Uma sinokuthile okukhulu okushayelwa yinjini kagesi, lapho-ke uma ubhuleka, amandla emishini angashintshwa abuyele kumandla kagesi futhi abuyiselwe ohlelweni. Le ndlela isetshenziswa ngenkuthalo embonini nasekuthuthweni: inciphisa ukusetshenziswa kwamandla, kodwa ayihambisani kabi nezinto zamandla ezingaphazamiseki. Esimisweni sokululama kufanele zisetshenziswe ngokucophelela okukhulu.
Ukwenziwa kabusha kuhlangana nini ne-UPS?
Inkinga ivela ngezinhlobo ezithile zemithwalo yezimboni, ngokuvamile lezi uhlobo oluthile lwamathuluzi omshini noma amanye amadivaysi aqhutshwa ngomshini. Zilawulwa yiziguquli ezibizwa ngokuthi ama-frequency converters noma ama-servos, okuyiziguquli zemvamisa ezinempendulo. Lapho injini yokufaka okunjalo ingasanikezwa amandla, ingashintshela kumodi ye-generator, iqale ukukhiqiza ugesi ngesikhathi sokubhuleka futhi iwunikeze kunethiwekhi yokufaka.
Ukufakwa kabusha kwezimboni zesimanje ngokuvamile zivikelwe ekuhlulekeni kwamandla kusetshenziswa i-UPS. Isibonelo, singacabangela imishini ye-CNC esetshenziselwa ukucubungula okunembayo kwezinto zokusebenza ezibizayo. Umjikelezo wezobuchwepheshe kufanele ugcwaliswe ngendlela efanele, futhi uma inqubo iphazamiseka, ngeke kwenzeke ukuyibuyisela futhi umsebenzi wokusebenzela kuzodingeka ulahlwe. Kungabiza ama-ruble angaphezu kwesigidi, uma sikhuluma ngobunjiniyela bemishini, ukwakhiwa kwemikhumbi nokukhiqizwa kwezindiza, kanye nobuchwepheshe bezempi nomkhathi.
Kungani ama-UPS engahambisani nokululama?
Isiguquli sefrikhwensi sidlulisa ugesi okhiqiziwe futhi siwukhiphe kokokufakayo. Kulokhu, uhlelo lokuphatha ukunikezwa kwamandla kufanele lucabangele ukuthi kungenzeka yini ukubuyisela amandla kunethiwekhi ukuze asetshenziswe ngokunenzuzo. Uhlelo olunjalo lubalwa ngokucophelela futhi lubiza kakhulu, kodwa likuvumela ukuthi unciphise izindleko zamandla futhi ugweme izingozi. Uma ukufakwa okuningana okuvikelwe nge-UPS kusebenza ngesikhathi esisodwa, amandla akhiqizwe okukodwa kwawo angasetshenziswa omakhelwane. Uma kunezinkinga ngokuphathwa komthwalo nokubala, noma iyunithi eyodwa kuphela esebenza ohlelweni, ukululama kuzothinta i-UPS. Amadivayisi akhiwe ngokuvumelana nohlelo lwe-classical awaklanyelwe lokhu: amandla adlula ku-inverter, eqala ukudlala indima yohlobo lwe-booster, okuholela ekwandeni kwe-voltage ebhasini le-DC. Cishe ayikho i-UPS yesimanje ekwazi ukubhekana ngokuphelele nale nkinga; ngemuva kokuthi isivikelo siqalisiwe, sizoshintshela kumodi yokudlula.
Iphi indlela yokuphuma?
Ukuvimbela isiguquli semvamisa ekuqhumeni, lapho amandla akhiqizwa ukufakwa ngesikhathi sokululama engena ohlelweni, amamojula akhethekile anama-braking resistors afakiwe. Zifakwe kumjikelezo ngesikhathi esifanele, zichitha amandla amaningi ngendlela yokushisa futhi, ngaphezu kwemishini yezimboni, futhi zivikela i-UPS. Inkinga, siphinda, ixazululwa kakade esigabeni sokuklama senkimbinkimbi yezobuchwepheshe: umthwalo kanye nesistimu yokuphatha amandla kufanele ilungiswe kahle. Ungakwazi futhi ukuxhuma ama-UPS amaningana ngokuhambisana ngomthwalo omncane - kulokhu, ukululama "kuchotshozwa" ngamandla futhi ngeke kusakwazi ukukhubaza uhlelo lokuphakelwa kwamandla olungaphazamiseki.
