Kuongororwa kwemabasa mana makuru estarter yakapfava: kutanga-kumisa zvakanaka, dziviriro dzakawanda, uye kushanda kwekuchengetedza simba.

1. Muhurongwa hwemagetsi, sekiyi Kudzora Mota Muchina uyu, soft starter inogadzirisa matambudziko akawanda anokonzerwa nenzira yechinyakare yekutanga zvakananga nekugona kwayo kudzora maitiro ekutanga mota. Haingobatidzi kana kudzima circuit chete, asi inoita kuti magetsi emota nemagetsi zvigadzike zvakanaka kuburikidza netekinoroji yemagetsi, nokudaro ichiwana mabasa akasiyana-siyana epakati uye ichipa rutsigiro rwakasimba rwekushanda zvakanaka uye kwakachengeteka kwekugadzirwa kwemaindasitiri. Mabasa makuru esoft starter anoongororwa zvakadzama pazasi, netsananguro dzinoenderana dzeChirungu.

2. Iri ndiro basa rekutanga uye guru re soft starter. Nzira yechinyakare yekutanga mota zvakananga inoita kuti mota ikwanise kutakura magetsi emagetsi anoputika ka5-8 kupfuura magetsi akayerwa panguva yekutanga. Aya magetsi makuru anokurumidza haangokonzere chete kushushikana kwakanyanya kwemagetsi pamagetsi emota, anokurumidzisa kukwegura kwe insulation, uye anopfupisa hupenyu hwebasa remota, asiwo anokonzera kuchinja kukuru kwemagetsi emagetsi, zvichikanganisa mashandiro ezvimwe zvishandiso zvemagetsi mu grid imwe chete, uye zvinogona kutokonzera Magetsi kukundikana kwakadai sekugumburwa.

3. Chinotangisa mota chinoshandisa tekinoroji yekudzora mashandisirwo emagetsi emagetsi akadai sethyristors. Pakutanga kwekutanga kwemotokari, kona yekufambisa yethyristor inowedzerwa zvishoma nezvishoma, kuitira kuti voltage yekupinda yemota iwedzere zvishoma nezvishoma kubva pamutengo wakaderera kusvika pavoltage yakayerwa. Munguva iyi, simba rekutanga remota rinodzorwa zvakanyanya mukati menguva ye1.5-4 yazvino yakayerwa, uye torque yekutanga inowedzerawo zvishoma nezvishoma, zvichidzivirira kudedera, kukanganiswa uye ruzha rusina kujairika rwesystem yekutumira michina inokonzerwa nesimba rakawandisa rekukurumidza, zvichidzivirira mota, reducer, coupling nezvimwe zvishandiso, uye kuderedza mari yekugadzirisa michina.

4. Pamusoro pekudzora maitiro ekutanga, soft starter inewo Chinomira Nyoro basa, iro rakakosha zvikuru mumamiriro ezvinhu ane zvinodiwa zvakanyanya zvekumira. Nzira yechinyakare yekumira kwemota zvakananga inowanikwa nekudzima magetsi ipapo ipapo, uye mota inomira nekukurumidza kana isingashande, izvo zvinozokonzera kukanganiswa kwakanyanya uye kudedera kwemutoro wemakanika. Semuenzaniso, mumidziyo yakaita semabhandi ekufambisa uye mahoist, kumira zvakananga kunogona kukonzera kuunganidzwa kwezvinhu, kukuvara kwezvikamu zvemuchina, uye kunyange tsaona dzekuchengetedza.

5. Basa rekumisa mota zvinyoro nyoro rinodzikisa kona yekufambisa mota yethyristor zvishoma nezvishoma, zvekuti voltage yekupinda mumota inodzikiswa zvishoma nezvishoma kubva pavoltage yakatarwa kusvika pazero, uye kumhanya kwemota kunodzikira zvishoma nezvishoma kusvika yamira zvakanaka. Maitiro aya anodzivirira simba reinertial pasystem yemakanika uye anovimbisa kugadzikana kwemaitiro ekumisa mota. Panguva imwe chete, kune mimwe michina inoda nzvimbo chaiyo yekupaka mota, basa rekumisa mota zvinyoro nyoro rinogonawo kushanda pamwe chete nepfungwa yekudzora yakakodzera kuti ivandudze kururama kwenzvimbo yekupaka mota uye kuwedzera kugadzikana kwemaitiro ekugadzira mota.

6. Chinotangisa zvinyoro nyoro chinobatanidza zvakakwana Dziviriro yeMotokari mabasa, ayo anogona kutarisa maparamita akakosha panguva chaiyo yekushanda kwemota, akadai semagetsi, voltage, tembiricha, nezvimwewo. Kana maparamita asina kujairika akaonekwa, matanho ekudzivirira anotorwa nenguva kudzivirira kukuvara kwemota. Pakati pawo, kudzivirira kuwedzeredza uye kudzivirira kuwedzeredza ndiwo mabasa ekudzivirira anonyanya kushandiswa.

7. Panyaya yekudzivirira overload, module yekuona current iri mukati me soft starter inoramba ichitarisa mashandiro emota. Kana current ikadarika kukosha kwakarongwa uye ikagara kwenguva yakati (yakaiswa zvichienderana nehunhu hwe overload yemota), soft starter ichaona kuti mota iri mu overload state, yobva yatumira chiratidzo chekudzivirira, yodzima simba remota kana kuderedza voltage inobuda, kuitira kudzivirira mota kuti isatsve nekuda kwe overload kwenguva refu. Overcurrent protection inonyanya kuitirwa ma currents makuru panguva yekutanga kana kushanda, senge motor short circuit, kuwedzera kamwe kamwe kwemutoro, nezvimwewo. Kana current ikadarika overcurrent threshold yakatarwa, soft starter ichaita nekukurumidza kuti iwane dziviriro nekukurumidza.

8. Pamusoro pezvo, mamwe ma soft starter emhando yepamusoro ane mabasa akadai sekudzivirira undervoltage, kudzivirira overvoltage, kudzivirira phase failure, uye kudzivirira overheating motor. Semuenzaniso, kana grid voltage iri pasi kana kupfuura imwe range ye rated voltage, undervoltage kana overvoltage protection function inotanga kudzivirira kukuvara kwemota kunokonzerwa nekushanda pasi pe voltage isina kujairika; kana simba remota rema phase matatu risipo, phase failure protection function inogona kuona nekudzima simba remota nenguva kudzivirira kuti mota isatsve nekuda kwe single-phase operation. Kubatanidzwa kwemabasa aya ekudzivirira kunoita kuti soft starter ive "security guard" yekushanda kwemota.

9. Mune zvimwe zviitiko zvekushanda zvine mwero wakaderera wemutoro, zvakaita semafeni, mapombi emvura nezvimwe zvishandiso, kana mota ichishanda nemagetsi akarongwa, chiitiko chekuti "bhiza guru rinodhonza ngoro diki" chinoitika, zvichikonzera kurasikirwa nesimba remagetsi kwakawanda. Basa rekushandisa simba restarter yakapfava rinogadzirisa simba remagetsi emota kuti rienderane nesimba remagetsi rinobuda remota nezvinodiwa nemutoro, nokudaro zvichizadzisa chinangwa chekuchengetedza simba.

10. Nheyo yayo yekuchengetedza simba yakavakirwa pahunhu hwesimba remota: kana mutoro wemota wakareruka, simba remota rinenge rakaderera. Panguva ino, kuderedza voltage yekupinda yemota kuburikidza nestarter yakapfava kunogona kuvandudza simba remota uye kuderedza kushandiswa kwesimba rinoita basa. Microprocessor iri mukati mestarter yakapfava ichaona nguva chaiyo yemutoro uye simba remota, uye inogadzirisa otomatiki angle yekufambisa yethyristor zvichienderana nemhedzisiro yekuona kuti iwedzere simba remota. Maitiro anoratidza kuti mune zviitiko zvine load rate ye30%-70%, mhedzisiro yekuchengetedza simba yestarter yakapfava yakakosha zvikuru, iyo inogona kuwana chiyero chekuchengetedza simba che5%-20%, ichideredza mari yakawanda yemagetsi kumabhizinesi.

11. Nemabasa makuru akadai sekutanga mota zvakanaka, kumira zvakanaka, dziviriro dzakawanda uye kushanda zvakanaka kwesimba, starter inonyorova haingogadzirisi chete kugadzikana uye kuchengetedzeka kwekushanda kwemota, inowedzera hupenyu hwekushanda kwemidziyo, asiwo inoderedza kushandiswa kwesimba uye mari yekugadzirisa. Yakashandiswa zvakanyanya muminda yakawanda senge kugadzirwa kwemaindasitiri, kuvaka, uye kuchengetedza mvura. Nekuvandudzwa kuri kuramba kuchiitwa kwetekinoroji yemagetsi yemagetsi uye tekinoroji yekudzora yakangwara, mabasa estarter inonyorova achawedzerwa uye achavandudzwa, zvichiunza mhinduro dzinoshanda uye dzakangwara mumunda wekudzora mota.
