Uhlalutyo lwemisebenzi emine ephambili yesiqalo esithambileyo: ukuqala nokuyeka okutyibilikayo, ukhuseleko oluninzi, kunye nokusebenza okonga amandla.

1. Kwinkqubo yokuqhuba umbane, njengesitshixo Ulawulo lweeMoto Kwisixhobo, i-soft starter isombulula ngempumelelo iingxaki ezininzi ezibangelwa yindlela yendabuko yokuqalisa ngokuthe ngqo kunye nokukwazi kwayo ukulawula ngokuchanekileyo inkqubo yokuqalisa i-motor. Ayivuli okanye icime nje i-circuit, kodwa iyazilungisa kakuhle i-motor voltage kunye ne-current ngokusebenzisa itekhnoloji ye-elektroniki yamandla, ngaloo ndlela ifezekisa imisebenzi eyahlukeneyo ephambili kwaye inika inkxaso enamandla yokusebenza ngokufanelekileyo nangokukhuselekileyo kwemveliso yemizi-mveliso. Imisebenzi ephambili ye-soft starter ihlalutywe ngokweenkcukacha ngezantsi, kunye neenkcazo zesiNgesi ezihambelanayo.

2. Lo ngumsebenzi osisiseko noyintloko we-soft starter. Indlela yendabuko yokuqalisa i-direct motor ibangela ukuba i-motor ibe nomsinga wokungena ophindwe ka-5-8 kunomsinga olinganisiweyo ngexesha lokuqalisa. Lo msinga omkhulu okhawulezileyo awubangeli nje kuphela uxinzelelo olukhulu lwe-electrothermal kwii-windings ze-motor, ukhawulezisa ukuguga kwe-insulation, kwaye unciphisa ubomi benkonzo ye-motor, kodwa ubangela nokuguquguquka okukhulu kwi-voltage ye-grid, okuchaphazela ukusebenza okuqhelekileyo kwezinye izixhobo zombane kwi-grid efanayo, kwaye unokubangela nokuba Ukunikezwa Amandla ukungaphumeleli okufana nokukhubeka.

3. I-starter ethambileyo isebenzisa itekhnoloji yokulawula isigaba sezixhobo ze-elektroniki zamandla ezifana ne-thyristors. Kwinqanaba lokuqala lokuqalisa i-motor, i-engile yokuqhuba ye-thyristor inyuswa kancinci kancinci, ukuze i-voltage yokufaka ye-motor inyuswe kancinci nangokuthe ngcembe ukusuka kwixabiso eliphantsi ukuya kwi-voltage elinganisiweyo. Ngexesha lale nkqubo, i-starting current ye-motor ilawulwa ngokungqongqo ngaphakathi koluhlu lwe-1.5-4 amaxesha e-current elinganisiweyo, kwaye i-torque yokuqala nayo iyanda ngokuthe ngcembe, ithintela ukungcangcazela, impembelelo kunye nengxolo engaqhelekanga yenkqubo yokudlulisa umatshini ebangelwa ngamandla amaninzi e-impact ngoko nangoko, ikhusela ngempumelelo i-motor, i-reducer, i-coupling kunye nezinye izixhobo, kwaye inciphisa iindleko zokugcinwa kwezixhobo.

4. Ukongeza kulawulo lwenkqubo yokuqalisa, i-soft starter ikwanayo ne- Ukuma okuthambileyo umsebenzi, obaluleke kakhulu kwiimeko ezineemfuno eziphezulu zenkqubo yokumisa. Indlela yendabuko yokumisa imoto ngokuthe ngqo ifezekiswa ngokunqumla umbane ngoko nangoko, kwaye imoto iya kuma ngokukhawuleza phantsi kwesenzo se-inertia, esiya kubangela impembelelo enkulu kunye nokungcangcazela komthwalo woomatshini. Umzekelo, kwizixhobo ezinje ngeebhanti zokuhambisa kunye nee-hoists, ukuma ngokuthe ngqo kunokubangela ukuqokelelana kwezinto, umonakalo kwizixhobo zezixhobo, kwaneengozi zokhuseleko.

5. Umsebenzi wokumisa okuthambileyo we-starter ethambileyo uyayinciphisa kancinci i-engile yokuqhuba ye-thyristor, ukuze i-voltage yokufaka yemoto incitshiswe kancinci kancinci ukusuka kwi-voltage elinganisiweyo ukuya kwi-zero, kwaye isantya semoto sinciphe kancinci ide ime ngokuzinzileyo. Le nkqubo ithintela ngempumelelo impembelelo yamandla angenamsebenzi kwinkqubo yoomatshini kwaye iqinisekisa uzinzo lwenkqubo yokumisa. Kwangaxeshanye, kwezinye izixhobo ezifuna indawo yokupaka echanekileyo, umsebenzi wokumisa okuthambileyo unokusebenzisana ne-logic yolawulo efanelekileyo ukuphucula ukuchaneka kwendawo yokupaka kunye nokuphucula uzinzo lwenkqubo yemveliso.

6. I-starter ethambileyo idibanisa i-comprehensive Ukhuseleko lweeMoto imisebenzi, enokujonga iiparameter eziphambili ngexesha lokusebenza kwemoto, ezinje ngombane, i-voltage, ubushushu, njl. Xa kufunyenwe iiparameter ezingaqhelekanga, amanyathelo okukhusela athathwa ngexesha elifanelekileyo ukuze kuthintelwe umonakalo wemoto. Phakathi kwazo, ukhuseleko olugqithisileyo kunye nokhuseleko olugqithisileyo zezona misebenzi zokukhusela ezisetyenziswa kakhulu.

7. Ngokuphathelele ukhuseleko lokugqithisa, imodyuli yokufumanisa umbane ngaphakathi kwi-starter ethambileyo isoloko ijonga umbane osebenzayo wemoto. Xa umbane udlula ixabiso elilinganisiweyo kwaye uhlala ixesha elithile (elimiselwe ngokweempawu zokugqithisa kwemoto), i-starter ethambileyo iya kugweba ukuba imoto ikwimeko yokugqithisa, ithumele ngoko nangoko isignali yokukhusela, inqumle umbane wemoto okanye inciphise i-voltage yokuphuma, ukuze ithintele ukuba imoto ingatshi ngenxa yokugqithisa ixesha elide. Ukhuseleko lokugqithisa lujoliswe ikakhulu kwi-currents ezinkulu ezikhawulezileyo ngexesha lokuqalisa okanye ukusebenza, njenge-motor short circuit, ukunyuka ngequbuliso komthwalo, njl. Xa umbane udlula umda omiselweyo wokugqithisa umbane, i-starter ethambileyo iya kusebenza ngokukhawuleza ukuze ifumane ukhuseleko olukhawulezileyo.

8. Ukongeza, ezinye iziqalisi ezithambileyo eziphezulu nazo zinemisebenzi efana nokukhusela umbane ongaphantsi kwamandla, ukukhusela umbane ongaphezulu kwamandla, ukukhusela ukungaphumeleli kwesigaba, kunye nokukhusela ubushushu bemoto. Umzekelo, xa i-voltage yegridi iphantsi okanye iphezulu kunoluhlu oluthile lwe-voltage elinganisiweyo, umsebenzi wokukhusela umbane ongaphantsi kwamandla okanye umbane ongaphezulu kwamandla uya kuqala ukunqanda umonakalo kwimoto obangelwa kukusebenza phantsi kombane ongaqhelekanga; xa umbane wesigaba sesithathu semoto ungekho, umsebenzi wokukhusela ukungaphumeleli kwesigaba unokubona kwaye unqumle umbane ngexesha ukuthintela imoto ekutshisweni ngenxa yokusebenza kwesigaba esinye. Ukuhlanganiswa kwale misebenzi yokukhusela kwenza i-starter ethambileyo ibe "ngumlindi wokhuseleko" wokusebenza kwemoto.

9. Kwezinye iimeko zokusebenza ezinezinga lomthwalo eliphantsi, njengeefeni, iimpompo zamanzi kunye nezinye izixhobo, xa imoto isebenza ngevolthi elinganisiweyo, kuya kwenzeka into yokuba "ihashe elikhulu litsala inqwelo encinci", nto leyo ebangela inkunkuma enkulu yamandla ombane. Umsebenzi wokonga amandla we-starter ethambileyo ulungisa ngamandla ivolthi yokufaka yemoto ukuze ihambelane namandla okukhupha emoto kunye neemfuno zomthwalo, ngaloo ndlela kufezekiswa injongo yokonga amandla.

10. Umgaqo wayo wokonga amandla usekelwe kwiimpawu zamandla zemoto: xa umthwalo wemoto ulula, amandla emoto aphantsi. Ngeli xesha, ukunciphisa amandla okufaka i-motor nge-starter ethambileyo kunokuphucula amandla emoto kwaye kunciphise ukusetyenziswa kwamandla okusabela. I-microprocessor engaphakathi kwi-starter ethambileyo iya kubona ngexesha langempela umthwalo wangoku kunye namandla emoto, kwaye ilungise ngokuzenzekelayo i-engile yokuqhuba ye-thyristor ngokweziphumo zokufumanisa ukuze ilungelelanise amandla ombane emoto. Ukuziqhelanisa kubonisa ukuba kwiimeko ezinesantya somthwalo se-30%-70%, isiphumo sokonga amandla se-starter ethambileyo sibaluleke kakhulu, esinokufikelela kwisantya sokonga amandla se-5%-20%, sinciphise iindleko ezininzi zombane kumashishini.

11. Ngemisebenzi ephambili efana nokuqalisa okutyibilikayo, ukuyeka okuthambileyo, ukhuseleko oluninzi kunye nokusebenza okonga amandla, i-soft starter ayiphuculi nje kuphela uzinzo kunye nokhuseleko lokusebenza kwemoto, yandisa ubomi benkonzo yezixhobo, kodwa ikwanciphisa ukusetyenziswa kwamandla kunye neendleko zokugcina. Isetyenziswe kakhulu kwiindawo ezininzi ezifana nemveliso yemizi-mveliso, ulwakhiwo, kunye nokugcinwa kwamanzi. Ngophuhliso oluqhubekayo lwetekhnoloji yamandla e-elektroniki kunye netekhnoloji yokulawula ekrelekrele, imisebenzi ye-soft starter iya kuphuculiswa ngakumbi kwaye iphuculwe, izise izisombululo ezisebenzayo nezikrelekrele ngakumbi kwicandelo lolawulo lweemoto.
