Umbane ophezulu wombane wesiqalo othambileyo wekhabhinethi yelizwe ulungele ikakhulu (3 ~ 10kV) ikheji ye-squirrel asynchronous motor start and stop control and protection. Amacandelo aphezulu e-anti-parallel thyristor kunye nezixhobo zokulawula i-elektroniki zixhunyiwe phakathi kwe-stator winding ye-motor high voltage kunye nokunikezelwa kwamandla. Xa i-motor iqala, ngokomthetho othile (njenge-slope yangoku okanye i-voltage rhoqo) ilawula intlanzi yokuqhuba i-tube ye-interproduct, kwaye ngokuqhubekayo utshintshe igalelo leqela lokugqibela le-stator ukusuka kuxinzelelo ukuya kuxinzelelo olupheleleyo, emva kokuqala kugqityiwe, umnxibelelanisi wokugqitha uzotyiwe. Inomsebenzi wokukhusela impazamo efana ne-over-cut, i-short-phase starting, i-peak overcurrent, njl.njl Ukuyisebenzisa kunokuphepha ngokufanelekileyo impembelelo eyingozi ebangelwa yi-motor ngokugqithisileyo ukuqala ngoku kwigridi yamandla, kwaye ngokuqhelekileyo ingasebenzisa i-motor-power high-power. phantsi komthamo wegridi yamandla alinganiselweyo kunye nokwandisa ubomi bayo benkonzo. Ukongeza, iKhabhinethi yaseburhulumenteni ethambileyo ephezulu yombane inomsebenzi “wokumisa ethambileyo”, xa kuthe cwaka, i-motor stator winding voltage iya kuncitshiswa ngokutyibilikayo, ngaloo ndlela kuthintelwe ukuzinza ngequbuliso kwezixhobo, eziluncedo kwimpompo (inokuphepha. isiphumo sehamile yamanzi) okanye ibhanti lokuhambisa.
1. Ubungakanani obuncinci kunye nemisebenzi epheleleyo
Ikhabhinethi yeplanga idibanisa i-high-voltage solid-state soft-start-start, i-high-voltage switch switch, kunye ne-bypass cabinet kwikhabhinethi edibeneyo. Incinci ngobukhulu. Xa kuthelekiswa nekhabhathi yokutshintsha kwevoltage ephezulu kunye nekhabhathi yokufundisa,
Indawo yekhabhinethi yokuqalisa iyancipha ngesiqingatha, kwaye nayo inemisebenzi yokuqalisa okuthambileyo, ukumisa okuthambileyo, ukutshintshwa kwekhabhinethi kunye nekhabhinethi yokudlula.
2. Isiqalo sangoku sincinci kwaye umphumo wokugcina amandla ubalulekile
I-medium-and high-voltage switch eqinile-imeko ethambileyo-isiqalo ikhabhathi edibeneyo ilungelelanisa i-voltage ngokutshintsha i-angle yokuqhuba i-thyristor, ngaphandle kokulahlekelwa kwamandla kunye nokuqala okwangoku.
Incinci, i-2.5 ~ 3.5 amaxesha angoku alinganisiweyo.
3. Ikhono elinamandla lokuchasana nokuphazamiseka, ukulungelelanisa kwiindawo ezahlukeneyo zokusetyenziswa
Le khabhinethi yenzelwe isiphaluka esikhethekileyo sokumelana-i-capacitance absorption, enomsebenzi oqinileyo wokuchasana nokuphazamiseka. Ukusebenza kwemveliso kuzinzile, akuchatshazelwa bubushushu be-ambient kunye nendawo yejografi, kwaye inokuqaliswa rhoqo.
4. Imisebenzi yokukhusela ebanzi kunye nokhuseleko oluphezulu
Inemisebenzi yokukhusela impazamo efana nokugcwala, ilahleko yesigaba, kunye nokuqalisa i-peak overcurrent. Iiparamitha zokuqalisa zikhethwa, zilungelelaniswe kwaye ziyalawuleka.
5. Ukugcinwa kwasimahla, ukonga iindleko
Uyilo olungenalo ukugcinwa lunciphisa iintambo zocingo zeekhabhinethi zokutshintsha kwe-voltage ephezulu kunye neekhabhinethi zokuqala ezithambileyo. Akukho okunye ukugcinwa okufunekayo emva kokusetyenziswa, okunokonga imali eninzi kwiindleko zokulondoloza.
