Ingcaciso yeMveliso

I-GRJ uthotho lwe-voltage ephezulu ye-motor eqinile-imeko yokuqalisa ethambileyo sisixhobo sokuqala esithambileyo esisetyenziselwa ukuqalisa (6000V ~ 10000V) i-high-voltage ye-AC esynchronous okanye i-synchronous motors.Ilungele ubukhulu becala iinjini ze-AC eziphakathi kunye neziphezulu-voltage ezingaphantsi kwe-10KV.Yamkela itekhnoloji yolawulo ye-DSP ephucukileyo, itekhnoloji ye-elektroniki yamandla kunye nolunye uhlobo oluphambili.Idibanisa izigaba ezintathu ze-thyristor ezihambelanayo kunye nezixhobo zokulawula i-elektroniki phakathi kwe-stator winding ye-motor high-voltage kunye nokunikezelwa kwamandla.Xa i-motor iqala, i-angle conduction ye-thyristor ilawulwa ngokomgaqo othile (ofana ne-current current okanye i-voltage ramp), kunye ne-voltage yegalelo ye-stator winding ye-motor iguqulwa ngokuqhubekayo de i-voltage epheleleyo.Emva kokuba ukuqaliswa kugqityiwe, i-contactor yokudlula iyatsalwa.Ukongeza, uchungechunge lwe-GRJ olunevoltage ephezulu ye-motor solid-state soft starter nayo inomsebenzi "we-soft stop".Ngexesha lokumisa okuthambileyo, i-motor stator winding voltage iya kuncitshiswa ngokutyibilikayo, ngaloo ndlela ukucima ukumisa ngequbuliso kokuqhuba.Okanye amabhanti okuhambisa aluncedo.
Xa kuthelekiswa nezinye iindlela zokuqalisa zemveli, indlela yayo ekhethekileyo yolawulo olukrelekrele ayinakuseta ngokulula nangokuchanekileyo iiparamitha ezifana nokuqalisa itorque, ukuqala ngoku, ixesha lokuqalisa, ixesha lokumisa, njl., kodwa nolawulo lwenethiwekhi nge-microcomputer kunye ne-PLC.Ngoku kwimveliso yoomatshini, imveliso yesamente, isinyithi, imigodi, imveliso yeoli, imveliso yeekhemikhali, unyango lwamanzi, iimpompo zepetrochemical kunye namanye amashishini, iimpompo, iiyunithi zokumpompa, iicompressor zomoya, iibhola zokusila, iikhreyini, iicompressors, izityuli, abahambisi, iilifti, isetyenziswa ngokubanzi kwimithwalo eyahlukeneyo efana ne-centrifuges kunye nee-rolling Mills.Iziqalisi ezithambileyo zoxinzelelo oluphezulu zolwelo ziya kupheliswa.

Inkcazo yoMfanekiso

Iiparamitha zobugcisa kunye nemilinganiselo yesakhiwo

Iimpawu zemveliso kunye nobungakanani bokusetyenziswa

1. Ukuqala okugudileyo kunye nokuma okuthambileyo kunqande ingxaki yokunyuka kunye nesiphumo sehamile samanzi sezixhobo zokuqala;
2. Iindlela ezahlukeneyo zokuqalisa kunye noluhlu olubanzi lwezicwangciso zangoku kunye ne-voltage zingatshintshwa kwiimeko ezahlukeneyo zomthwalo kunye nokuphucula inkqubo.
3. Ukuphucula umsebenzi othembekileyo wokukhusela kunye nokukhusela ngokufanelekileyo ukhuseleko lwemoto kunye nezixhobo ezinxulumene nazo.
4. Ukunciphisa i-current current ye-motor kunokuphepha ukuhla kwe-voltage kunye ne-voltage dip kwi-power supply.Ukunciphisa umthamo wokuhambisa amandla kwaye uphephe utyalo-mali ekwandiseni umthamo.
5. Ukunciphisa uxinzelelo lokuqalisa kunye nokwandisa ubomi benkonzo yemoto kunye nezixhobo ezinxulumene nazo.Gcina iindleko zokugcina kwaye wonge imali eninzi.
Ubumbeko lwesixhobo sokuqala esithambileyo:
Yahlulwe yangamacandelo amabini: ikhabhathi ephezulu yokuphuma kwemoto, intambo esuka kwikhabhathi yokuqalisa imoto ukuya kwikhabhathi ethambileyo yokuqalisa, kunye nentambo esuka kwikhabhathi ethambileyo yokuqalisa ukuya kwimoto.Integrated high-voltage eqinileyo-state kwikhabhathi ethambileyo-isiqalo, switsha kwikhabhinethi kunye soft-ukuqala zidityaniswe kwikhabhathi enye switsha, nto leyo encinci ngobukhulu kwaye kulula ukuyifaka, kwaye ingafakelwa kunye nezinye iikhabhathi switsha.
Iimeko eziqhelekileyo zokusebenza:
(1) Umda ophezulu wobushushu be-ambient awukho ngaphezu kwe-50 ° C (ubushushu obuqhelekileyo kwiiyure ezingama-24 alikho ngaphezu kwama-35 ° C), kwaye umda ophantsi awukho ngaphantsi kwe -15 ° C;
(2) Ukufuma okuhambelanayo akudluli kwi-95%;ukuphakama akudluli kwi-1000m, kwaye umthamo kufuneka uncitshiswe xa udlula i-1000m;
(3) Kufuneka ibekwe ngaphakathi, ngaphandle kokungcangcazela nomothuko kakhulu, kwaye ingabi nabungozi bomlilo nokudubula;
(4) Uthuli oluqhubayo kunye negesi eyingozi ayivumelekanga.
