I-3kv 6kv 11kv i-Medium Voltage Motor Soft Starter ikhabhinethi yeMpompo yaManzi
1. Isimahla kulondolozo: I-Thyristor sisixhobo sombane esingenabafowunelwa.Ukwahluka kwezinye iintlobo zeemveliso ezifunayo
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: Inkqubo epheleleyo yokulawula nokukhusela ukuqala kwemoto.Iyakwazi ukufaka
ukusebenza kuphela ngentambo yamandla kunye nentambo yemoto edibeneyo.Yonke inkqubo inokuvavanywa ngombane phantsi kombane ophantsi phambi kokuba isebenze ngamandla ombane aphezulu.
3. I-Backup: I-starter ifika ixhotywe nge-vacuum contactor engasetyenziselwa ukuqala i-motor ngqo ngaphakathi.Ukuba ihluleka, i-vacuum contactor ingasetyenziselwa ukuqala i-motor ngqo ukuqinisekisa ukuqhubeka kwemveliso.
4. I-thyristor ye-voltage ephezulu yinxalenye ye-loop enkulu, ixhotyiswe nge-voltage
inkqubo yokukhusela ukulinganisa kunye nenkqubo yokukhusela i-voltage over-voltage.
5. Iza ixhotyiswe ngesixhobo sokuthintela umbane ngenxa yokoyika ukungena kwisixhobo sombane ophezulu kumbane.
urhulumente.
6. Ubuchwephesha obuphezulu bokuhambisa ifayibha ye-optical iqonda ukukhangela okubangela ukuba i-thyristor yombane ophezulu kunye nokwahlula phakathi kwe-loops yokulawula i-LV.
7. I-microcontroller ye-DSP isetyenziselwa ukwenza ulawulo oluphakathi oluyixesha langempela kunye nokusebenza okuphezulu kunye nokuthembeka okuphezulu kunye nokuzinza okuhle kakhulu.
8. I-LCD/inkqubo yokubonisa isikrini kwisiTshayina kunye nesiNgesi kunye nojongano lokusebenza olunobuntu.
9. I-RS-485 ichweba lonxibelelwano ingasetyenziselwa ukunxibelelana nekhompyutheni ephezulu okanye iziko lolawulo eliphakathi.
10. Uvavanyo lokuguga lwenziwa kuzo zonke iibhodi zeesekethe
