Njengoko amashishini amaninzi eqonda izibonelelo zokusebenza kakuhle kwamandla kunye nokuzinza kokusingqongileyo, kukho imfuno ekhulayo yezixhobo ezinokunciphisa ukusetyenziswa kwamandla kwizixhobo zoshishino.Esinye isixhobo esinjalo sisiqalisi esithambileyo sombane ophakathi.
I-11kv motor ethambileyoabaqalisiziyilelwe ukunceda ukulawula umsinga wokuqalisa wemoto, enokuba phezulu kakhulu kwaye itye amandla.Ngokunciphisa ukuqala kwangoku, iziqalo ezithambileyo zinciphisa uxinzelelo kwi-motor kwaye zandise ubomi bayo, ngelixa zinciphisa ukusetyenziswa kwamandla kunye neendleko.
Ke, isebenza njani i-medium voltage motor motor soft starter?Konke kuqala ngonikezelo lwamandla.Xa i-starter ethambileyo inamandla, isebenzisa uluhlu lwezixhobo eziqinileyo, ezifana ne-thyristors, ukunyusa ngokuthe ngcembe amandla ombane ahanjiswe kwi-motor.Koku kunyuka ngokuthe ngcembe ukuba isiqalisi esithambileyo sithiywe sona, njengoko sivumela imotor ukuba iqale ngokutyibilikayo nangokucothayo.
Njengoko i-voltage isanda ngokuthe ngcembe, ukuqala kwangoku kwemoto kulinganiselwe, nto leyo enciphisa ukunxiba kunye nokukrazula kwi-motor windings kunye nezinye izinto.Oku kuvumela i-motor ukuba isebenze ngokufanelekileyo kwaye ngokuthembekileyo, ukunciphisa ithuba lokungaphumeleli okanye ukungaphumeleli ngequbuliso.
Ukongeza ekunciphiseni ukuqala kokusetyenziswa kwangoku kunye nosetyenziso lwamandla, iziqalisi ezithambileyo zombane ophakathi zinceda ukukhusela kwi-voltage sags kunye notshintsho lwamandla ombane olunokonakalisa imotor okanye ezinye izixhobo eziqhagamshelweyo.
Ewe kunjalo, ayizizo zonke iziqalo ezithambileyo ezenziwe ngokulinganayo, kwaye zininzi izinto ekufuneka uziqwalasele xa ukhetha isiqalisi esithambileyo esifanelekileyo kwisicelo sakho.Izinto ezinje ngomgangatho wemoto, iimpawu zomthwalo kunye neemfuno zamandla enkqubo zifuna uphononongo olucokisekileyo ukumisela esona siqalisi sithambileyo kwiimfuno zakho.
Uqwalaselo olubalulekileyo xa ukhetha isiqalisi esithambileyo kukutshintsha rhoqo.Ukutshintshela rhoqo kumisela ukuba kangaphi na izixhobo zombuso oqinileyo ezisetyenziswa kwiziqalisi ezithambileyo zivulwa kwaye zicinywe.I-frequency switching frequency ephezulu ivumela ulawulo oluchanekileyo ngakumbi lwangoku kunye nokunciphisa uxinzelelo kwi-motor, kodwa kwandisa ubushushu obuveliswa ngumqalisi othambileyo kwaye bufutshane ubomi bayo.
Ezinye izinto ekufuneka ziqwalaselwe xa ukhetha isiqalisi esithambileyo ziquka inqanaba lokhuseleko olunikezelwa sisixhobo (njengokukhuselwa kwe-overcurrent kunye ne-overvoltage), uhlobo lweprotocol yonxibelelwano exhaswayo (njenge-Modbus okanye i-Ethernet), nokuba isiqalisi esithambileyo sinokudityaniswa ngokulula. kwindawo yakho ekhoyo kwinkqubo yolawulo.
Ngesixhobo sokuqalisa esithambileyo esiphakathi esiphakathi, unokuvuna uluhlu lwezibonelelo ezibandakanya ukusetyenziswa kwamandla okunciphisa, ubomi obude bemoto, ukuthembeka okwandisiweyo kunye nolawulo olukhulu kwinkqubo yakho yeshishini.Nokuba uhlaziya inkqubo esele ikhona okanye ufaka injini entsha, isiqalisi esithambileyo esikumgangatho ophezulu sinokukunceda ukuba uhlangabezane nokusebenza kwamandla akho kunye neenjongo zozinzo ngelixa uphucula ukusebenza kunye nokunciphisa iindleko zokusebenza.
