Umbane oPhakathi oPhakathi weMoto eSoft Starter 3kv 6kv 10kv KwiSigaba esiThathu seMoto yoMbane yeAc
Isixhobo sokuqalisa esithambileyo sombane ophakamileyo luhlobo olutsha lwe-ac motor isixhobo sokutshintsha i-star-delta starter yesiqhelo, i-self-coupling voltage-drop starter kunye ne-magnetic control-drop starter.Isiqalo sangoku sinokuba ngaphantsi kunamaxesha angama-3 alinganiswe ngoku kwaye anokuqala ngokuphindaphindiweyo nangokuqhubekayo.
I-transformer yangoku ibona inqanaba lesithathu langoku kwaye lisetyenziselwa ukukhawulelana nokukhuselwa kwangoku.I-voltage transformer ibona i-voltage yesigaba sesithathu.Isetyenziselwa ukubonwa kwesigaba esivuselelweyo kunye nokukhuselwa kwamandla ombane wokugqithiswa kunye nokungabikho kwamandla.Umlawuli we-MCU ulawula i-thyristor yesigaba sokulawula i-Angle trigger, ngaxeshanye inciphisa i-voltage kwi-motor, inciphisa ukuqala kwangoku, kwaye iqala kakuhle i-motor de imoto ibaleke ngesantya esipheleleyo.Emva kokuba i-motor isebenza ngesantya esipheleleyo, tshintshela kwi-contactor ye-bypass.Isixhobo sokuqalisa esithambileyo esiphakathi siyaqhubeka ukubona iiparamitha zemoto ukukhusela imotor.Isixhobo sokuqalisa esithambileyo se-voltage ephezulu sinokunciphisa i-inrush yangoku yemoto kwaye sinciphise impembelelo kwigridi yamandla kunye nemoto ngokwayo.Kwangaxeshanye, ikwanciphisa ifuthe lomatshini kwisixhobo sokulayisha iimoto, yandisa ubomi benkonzo yesixhobo kunye nokunciphisa ukungaphumeleli kwemoto.Ibhodi yezitshixo kunye nemodyuli yokubonisa zonke iiparameters kunye nedatha yemo yesiqalisi esithambileyo semoto.
1. Isimahla kulondolozo: I-Thyristor sisixhobo sombane esingenabafowunelwa.Ngokwahlukileyo kwezinye iintlobo zeemveliso ezifuna ukugcinwa rhoqo kulwelo kunye neenxalenye njl.njl., ijika ukunyuswa koomatshini kubomi benkonzo yamacandelo e-elektroniki, ngoko ayifuni kugcinwa emva kokusebenza iminyaka emininzi.
2. Ufakelo olulula kunye nokusebenza: I-voltage ephakathi ye-motor ethambileyo yokuqalisa inkqubo epheleleyo yokulawula nokukhusela ukuqala kwemoto.Inokuthi isebenze kuphela ngomgca wamandla kunye nomgca wemoto odibeneyo.Yonke inkqubo inokuvavanywa ngombane phantsi kombane ophantsi phambi kokuba isebenze ngamandla ombane aphezulu.
3. I-Backup: I-starter ifika ixhotywe nge-vacuum contactor engasetyenziselwa ukuqalisa i-motor ngqo ngaphakathi.Ukuba ihluleka, i-vacuum contactor ingasetyenziselwa ukuqala i-motor ngqo ukuqinisekisa ukuqhubeka kwemveliso.
4. Isiqalisi esithambileyo samandla ombane aphezulu siza sixhotyiswe ngesixhobo sokuthintela i-electromagnetic ngenxa yokoyika ukungena kwisixhobo samandla ombane aphezulu kwimeko yombane.
5. Ubuchwephesha obuphezulu bokuhambisa ifayibha ye-optical iqonda ukuchongwa okubangela umbane ophezulu we-thyristor kunye nokwahlukaniswa phakathi kwe-loops yokulawula i-LV.
6. I-microcontroller ye-DSP isetyenziselwa ukwenza ulawulo oluphakathi oluyixesha langempela kunye nokusebenza okuphezulu kunye nokuthembeka okuphezulu kunye nokuzinza okuhle kakhulu.
7. I-LCD/inkqubo yokubonisa isikrini kwisiTshayina kunye nesiNgesi kunye nojongano lokusebenza olunobuntu.
8. I-RS-485 i-port yonxibelelwano ingasetyenziselwa ukunxibelelana nekhompyutheni ephezulu okanye iziko lolawulo eliphakathi.
9. Uvavanyo lokuguga lwenziwa kuzo zonke iibhodi zeesekethe
