8inch 10inch 11inch 12inch 36V 48V Hub Motors
Ngokuqhelekileyo, i-current efunwa yi-motor ekuqaliseni inkulu kakhulu kunomlinganiselo wangoku, omalunga namaxesha angama-6 angoku.Ngaphantsi kwangoku, i-motor iya kuba nempembelelo enkulu kunokuba isebenza ngokuqhelekileyo.Impembelelo enjalo iya kwandisa ilahleko yemoto, inciphise ubomi bemoto, kwaye ibangele nomonakalo kwezinye iindawo ngaphakathi komatshini xa umsinga mkhulu kakhulu.Phantsi kweemeko ezinjalo, abantu baqala ukunikela ingqalelo kuphando lwesiqalo esithambileyo semoto, ngethemba lokwenza imoto iqale ngokutyibilikayo nangokutyibilikayo kubuchwephesha obunxulumeneyo.
1, umgaqo wokuqalisa othambileyo wemoto
Kubugcisa bangaphambili, uphando kwisiqalo esithambileyo semoto kukulawula ukuqala kwenqanaba lesithathu le-AC motor asynchronous, kwaye isiqalo esithambileyo semoto sibonwa ngokusebenzisa inqanaba lesithathu le-AC motor asynchronous, ebonelela ngokhuseleko ekuqaleni. kunye nokuma kwemoto.Le teknoloji isetyenziswe ngokubanzi kwintsimi yezoshishino.Kumashishini, obu bugcisa busetyenziselwe ukubuyisela isiqalo se-Y/△ semveli, kwaye iziphumo ezilungileyo zifunyenwe.
I-Three-reverse parallel thyristor (SCR) inokulungelelanisa i-voltage ye-soft starter, kwaye ngumlawuli wombane we-soft starter.Xa i-thyristor ehambelanayo emithathu-reverse idibaniswe kwisiphaluka, idlala indima yokudibanisa phakathi kokunikezelwa kwamandla kunye ne-stator ye-motor.Xa ucofa ukuqalisa, i-voltage ngaphakathi kwe-thyristor iya kunyuka ngokuthe ngcembe, kwaye i-motor iya kuhamba ngokukhawuleza phantsi kwesenzo sombane.Xa isantya sokuhamba sifikelela kwisantya esifunekayo, i-thyristor iya kuvulwa ngokupheleleyo.Ngeli xesha, i-voltage ecofayo iyafana ne-voltage elinganisiweyo, engenakukwazi ukuqonda kuphela Phantsi kweemeko ezinjalo, i-motor iqhuba ngokuqhelekileyo phantsi kokhuseleko lwe-thyristor, eyenza i-motor ihlupheke impembelelo encinci kunye nelahleko, ngaloo ndlela yandisa kakhulu ubomi benkonzo. yenjini kunye nokugcina injini ikwimeko entle yokusebenza.

2. Itekhnoloji yokuqalisa ethambileyo yenjini ye-asynchronous
2.1, i-thyristor AC voltage elawula ukuqala okuthambileyo
Amandla ombane we-AC alawula isiqalo esithambileyo se-thyristor ikakhulu sitshintsha imowudi yoqhagamshelo lwe-thyristor, itshintsha indlela yoqhagamshelo yemveli ibe yidibaniso ukuya kumajiko amathathu, ngaloo ndlela iqonda unikezelo lwamandla kwi-thyristor ngokunxuseneyo.I-Thyristor soft starter inokulungelelaniswa okuqinileyo, ke abasebenzisi banokwenza uhlengahlengiso olufanelekileyo kwimoto ngokweemfuno zabo ezahlukeneyo, kwaye benze indlela yokuqalisa yemoto ilungele iimfuno zabo ngotshintsho oluhambelanayo.

2.2.Umgaqo wohlengahlengiso wesigaba esithathu sombane we-AC olawula isiqalisi esithambileyo
Amandla ombane akwinqanaba esithathu le-AC alawula isiqalisi esithambileyo sisebenzisa ngokupheleleyo ijiko lophawu lombane we-AC ukuqalisa injini.Umbono wokusebenzisa ijiko lophawu lombane we-AC ukuqonda ukuqala okuthambileyo kwemoto ngolu hlobo luluvo oluphambili lwesiqalisi esithambileyo semoto.Ikakhulu isebenzisa izibini ezintathu ze-thyristors ngaphakathi kwemoto ukudibanisa i-motor kuthotho, kwaye itshintsha ixesha lokuvula ngokulawula i-pulse ye-trigger kunye ne-angle yokuqalisa.Kule meko, i-terminal yokufaka i-motor inokugcina i-voltage eyaneleyo ukulawula ukuqala kwemoto.Xa i-motor iqaliswa, i-voltage iya kuba yi-voltage elinganisiweyo, emva koko abafowunelwa abathathu be-bypass baya kudibaniswa, kwaye i-motor inokudityaniswa kwigridi.
3. Izinto ezilungileyo zesiqalo esithambileyo ngaphezu kwesiqalo semveli
"Isiqalo esithambileyo" asikwazi ukunciphisa kakhulu impembelelo yokuqala yenkqubo yothumelo ngokwayo kwaye yandise ubomi benkonzo yamacandelo aphambili, kodwa ikwanciphisa kakhulu ixesha lempembelelo yemoto eqala ngoku, ukunciphisa umthwalo wempembelelo yobushushu kwimoto kunye nefuthe. kwigridi yamandla, ngaloo ndlela igcina amandla ombane kunye nokwandisa ubomi benkonzo yemoto.Ukongeza, ngokusebenzisa itekhnoloji "yokuqala ethambileyo", injini enomthamo omncinci unokukhethwa ekukhetheni iimoto, ngaloo ndlela inciphisa utyalo-mali olungeyomfuneko.Ukuqala kweenkwenkwezi kuxhomekeke ekutshintsheni i-wiring ye-motor winding, ngaloo ndlela ukutshintsha i-voltage ekuqaleni.I-voltage ekuqaleni-up iyancitshiswa, nto leyo eyenza ukuba ukuqalisa kwangoku kuncinci, kwaye impembelelo kwibhasi ekuqaleni iyancitshiswa, ukwenzela ukuba ukuhla kwamandla ombane ebhasi ekuqaleni kokuqalisa kuphakathi koluhlu oluvumelekileyo (kuyafuneka ukuba ukuhla kwamandla ebhasi akufanele kudlule i-10% yombane olinganisiweyo).Ukuqala kwe-decompression ngokuzenzekelayo kunokunciphisa okwangoku ekuqaliseni, okuphunyezwa ngokutshintsha itephu ye-voltage ye-auto-transformer.
Ngokomzekelo, iimfuno zegridi yamandla ekuqalisweni kwamaqela ama-4 ama-kilowatts angama-36.Ukusebenza okuqhelekileyo kwemoto ye-36 kW malunga ne-70A, kwaye i-current iqala ngokuthe ngqo malunga namaxesha angama-5 aqhelekileyo, oko kukuthi, okwangoku okufunekayo kumaqela amane eenjini ze-36 kW ukuqala ngexesha elifanayo yi-1400A;Imfuno yokuqalisa inkwenkwezi kumatshini wombane ngamaxesha angama-2-3 esiqhelo sangoku kunye ne-560-840A yegridi yamandla yangoku, kodwa iya kuba nefuthe elikhulu kumbane xa uqalisa, elilingana namaxesha angama-3 amandla ombane aqhelekileyo.Imfuno yesiqalo esithambileyo kwigridi yamandla kwakhona ngamaxesha angama-2-3 aqhelekileyo akhoyo, oko kukuthi, i-560-840A.Nangona kunjalo, impembelelo yesiqalo esithambileyo kwi-voltage imalunga ne-10%, eyona nto ingayi kuba nempembelelo enkulu.
