Isiqalisi esithambileyo sisixhobo esisetyenziselwa ukulawula inkqubo yokuqaliswa kwemoto. Iqala i-motor ngokutyibilikayo ngokunyusa ngokuthe ngcembe i-voltage, ngaloo ndlela inqanda ukutyhala okuphezulu ngoku kunye nokothuka koomatshini okubangelwa kukuqalisa ngokuthe ngqo. Nantsi indlela isiqalisi esithambileyo esisebenza ngayo kunye nezibonelelo eziphambili zokusebenzisa isiqalisi esithambileyo:
Sisebenza njani isiqalisi esithambileyo
Isiqalisi esithambileyo silawula ikakhulu ukuqala kwemoto ngala manyathelo alandelayo:
Ukusetyenziswa kombane wokuqala: Ngexesha lokuqala lokuqalisa kwemoto, isiqalisi esithambileyo sisebenzisa amandla ombane asezantsi kwimotor. Oku kunceda ukunciphisa ukuqala okwangoku kwaye kuthintele ukothuka kwigridi kunye nemoto ngokwayo.
Yandisa kancinane i-voltage: Isiqalisi esithambileyo sinyusa ngokuthe ngcembe i-voltage esetyenziswa kwi-motor, ngokuqhelekileyo ngokulawula i-thyristor (SCR) okanye isango elifakwe kwi-bipolar transistor (IGBT). Le nkqubo inokugqityezelwa ngexesha elimisiweyo, ivumela i-motor ukuba ihambe ngokukhawuleza.
Umlinganiselo ogcweleyo wombane: Xa inqwelo-mafutha ifikelela kwisantya sokuseta okanye emva kwexesha elimiselweyo lokuqala, isiqalisi esithambileyo sonyusa umbane ophumayo ukuya kumlinganiselo opheleleyo, uvumela imotor ukuba ibaleke ngesantya esiqhelekileyo sombane kunye nesantya.
I-Bypass contactor (ukhetho): Kwezinye iiplani, umqalisi othambileyo uya kutshintshela kwi-bypass contactor emva kokugqiba inkqubo yokuqalisa ukunciphisa ukusetyenziswa kwamandla kunye nobushushu be-starter ethambileyo ngokwayo, ngelixa ikwandisa ubomi besixhobo.
Iinzuzo zokusebenzisa isiqalisi esithambileyo
Nciphisa ukuqala ngoku: Isiqalo esithambileyo sinokunciphisa kakhulu i-inrush yangoku xa i-motor iqaliswa, ngokuqhelekileyo inciphisa i-current current ukuya kwi-2 ukuya ku-3 amaxesha angoku alinganisiweyo, ngelixa i-current ingaba phezulu kwi-6 ukuya ku-8 ngokuphindwe kabini ngexesha lokuqalisa ngokuthe ngqo. Oku akugcini nje ukunciphisa impembelelo kwigridi, kodwa kunciphisa uxinzelelo lomatshini kwi-motor windings.
Ukunciphisa ukutshatyalaliswa koomatshini: Ngenkqubo yokuqalisa egudileyo, iziqalo ezithambileyo zinokunciphisa impembelelo kunye nokunxiba kwamacandelo oomatshini kunye nokwandisa ubomi benkonzo yezixhobo zoomatshini.
Ukugcinwa kwamandla kunye nokukhuselwa kwendalo: Ngokulungisa inkqubo yokuqala, i-soft starter inciphisa inkunkuma yamandla ombane kwaye inciphisa ukulahlekelwa kwamandla ngexesha lenkqubo yokuqala, inceda ukufezekisa ukugcinwa kwamandla kunye neenjongo zokusingqongileyo.
Khusela i-motor: Iziqalo ezithambileyo zihlala zinemisebenzi eyahlukeneyo yokukhusela eyakhelwe-ngaphakathi, njengokukhusela ukulayisha ngaphezulu, ukukhuselwa kokushisa, ukukhuselwa kwe-undervoltage, njl., Enokuthi imise ngokuzenzekelayo ukusebenza kweemoto phantsi kweemeko ezingaqhelekanga kwaye ikhusele i-motor kumonakalo.
Ukuphucula ukuthembeka kwenkqubo: Abaqalisi abathambileyo banokuphucula ukuthembeka kwenkqubo yonke yamandla, ukunciphisa ukuphazamiseka kunye nefuthe kwezinye izixhobo xa i-motor iqaliswa, kwaye iqinisekise ukusebenza okuzinzile kwenkqubo.
Ukusebenza okulula kunye nokugcinwa: Umsebenzi wokulawula ngokuzenzekelayo we-starter ethambileyo yenza ukuqala kunye nokumisa i-motor ngakumbi kwaye kulawuleke ngakumbi, ukunciphisa ubunzima bemisebenzi yezandla kunye nokugcinwa rhoqo.
Ukusetyenziswa okubanzi: Iziqalisi ezithambileyo zifanelekile kwiindidi ezahlukeneyo zeenjini kunye nemithwalo, kubandakanya iimpompo, iifeni, iicompressors, amabhanti okuhambisa, njl., kwaye zineemeko ezininzi zesicelo.
Ukushwankathela, ngomgaqo wayo okhethekileyo wokusebenza kunye neengenelo ezahlukeneyo, isiqalisi esithambileyo siye saba sisixhobo esibalulekileyo sokulawula iimoto esisetyenziswa kakhulu kumashishini anamhlanje kunye nezorhwebo.
