Ukusetyenziswa kweisiqhoboshieresistorskwizixhobo ze-crane zibalulekile ekusebenzeni okukhuselekileyo nokusebenzayo koomatshini.Indlela yokusebenza yezixhobo zokuphakamisa kwi-crane kukuba: i-motor isebenza kwimeko yokuvelisa amandla xa ihamba phantsi, kwaye i-motor isebenza xa ihambela phezulu.Ukuba akukho mxhasi we-braking wongezwa, umbane owenziwe yi-motor uya kusebenza ngokuthe ngqo kwimodyuli ye-inverter, ebangela umonakalo rhoqo kwimodyuli.
Ngexesha lenkqubo yokunciphisa i-motor, inertia yezixhobo ezigqithisileyo ziyajikai-motor ibe yijenereyitha, ibangela ukuba i-motor inike amandla kwi-inverter kwelinye icala.Oku kunokubangela i-alam yombane ogqithisileyo kwi-inverter.Ukuze kulungiswe le ngxaki, indlela yokwandisa amandla okumelana (ngokunciphisa ngokufanelekileyo ixabiso lokumelana) ingasetyenziselwa ukukhulula amandla amaninzi.Ukongeza, ezinye izixhasi zokuqhobosha zinokubonelela ngonikezelo lwamandla umva kwiluphu yamandla, eluncedo ngakumbi kwiinkqubo eziguquguqukayo zama frequency kunye nebhasi ye-DC eqhelekileyo kwaye inceda ukonga amandla.
Iisiqhoboshieisixhasiidlala indima ebalulekileyo ekuthinteleni i-over-voltage ye-converter frequency ngexesha lokunciphisa, ukunciphisa umgama wokunciphisa, kunye nokuphucula ukusebenza okuguquguqukayo kwezixhobo zokuphakamisa.Nangona isiqhoboshi esakhelwe ngaphakathi semoto sisetyenziswa ikakhulu kwi-braking yokugqibela yokupaka, ayisebenzi ekuthotyweni isiqhoboshi.Apha kulapho i-restesive braking ingena khona njengoko ichaphazela kuphela i-motor ngexesha le-deceleration kwaye ayinamphumo xa imoto imisiwe.Ukugcina imoto imile phantsi komthwalo onokwenzeka, kufuneka kusetyenziswe isiqhoboshi.
Ngokubhekiselele kuhlobo lwe-resistors ye-brake esetyenziselwa ukuphakamisa izixhobo, i-aluminium ye-resistors ye-aluminium kunye ne-resistors ye-ripple idla ngokusetyenziswa ukuqala umthwalo.Ezi zixhasi zokuqhoqhobala nazo zinokubekwa phezu komnye, kodwa ingqwalasela eyodwa kufuneka inikwe ukhuseleko kunye nofakelo oluchanekileyo.Ukuba inani le-resistors lidlula i-4, kufuneka zibekwe kwisakhelo esikhethekileyo sesinyithi ngelixa zigcina umgama we-80mm phakathi kweeseti ezimbini ezikufutshane.Ukongezelela, isikhuselo sokushisa sinokufakwa phakathi ukuze kukhuselwe ukhuseleko olongezelelweyo.Kuyimfuneko ukuba kuqinisekiswe ukuba izikrufu zisekelwe ngokuqinileyo ukuthintela iingozi okanye ukutshitshiswa kombane kubasebenzi ngexesha lofakelo.
Ngamafutshane, ukusetyenziswa kwe resistors brake kwisixhobo se-crane kubalulekile ukulawula ukukhutshwa kwamandla ngexesha lokunciphisa, ukuthintela umonakalo kwi-converter frequency, kunye nokuphucula ukusebenza kunye nokhuseleko jikelele.Ufakelo olufanelekileyo kunye nokuqonda umsebenzi we-resistor braking kubalulekile ekusebenzeni ngokufanelekileyo koomatshini be-crane.
