Isethi yejeneretha ngokuvamile iqukethe injini, ijeneretha, isistimu yokulawula ephelele, isistimu yesekethe kawoyela, kanye nesistimu yokusabalalisa amandla.Ingxenye yamandla yejeneretha ebekwe ohlelweni lokuxhumana - injini ye-diesel noma injini ye-turbine yegesi - ngokuyisisekelo iyafana kumayunithi aphezulu kanye ne-low-pressure;Ukucushwa kanye nevolumu kaphethiloli yesistimu kawoyela kuhlobene kakhulu namandla, ngakho-ke awukho umehluko obalulekile phakathi kwamayunithi okucindezela okuphezulu nokuphansi, ngakho-ke awukho umehluko ezidingweni zokungenisa komoya kanye nezinhlelo zokukhipha umoya zamayunithi ahlinzeka ngokupholisa.Umehluko kumapharamitha nokusebenza phakathi kwamasethi ejeneretha anamandla kagesi aphezulu kanye namasethi ejeneretha ane-voltage ephansi kubonakala kakhulu engxenyeni yejeneretha kanye nengxenye yesistimu yokusabalalisa.
1. Umehluko wevolumu nesisindo
Amasethi ejeneretha kagesi aphezulu asebenzisa amajeneretha anamandla kagesi aphezulu, futhi ukwanda kwezinga likagesi kwenza izidingo zabo zokuvikela zibe phezulu.Ngokuhambisanayo, ivolumu nesisindo sengxenye yejeneretha kukhulu kunalezo zamayunithi ane-voltage ephansi.Ngakho-ke, umthamo womzimba uwonke kanye nesisindo sesethi yejeneretha engu-10kV kukhudlwana kancane kuneyunithi ye-low-voltage.Awukho umehluko obalulekile ekubukekeni ngaphandle kwengxenye ye-generator.
2. Umehluko wezindlela zokubeka phansi
Izindlela zokusekela ezingathathi hlangothi zamasethi amabili ejeneretha zihlukile.I-380V unit winding ixhumeke ngenkanyezi.Ngokuvamile, isistimu ye-low-voltage iyisistimu yokubeka phansi eqondile yephoyinti elingathathi hlangothi, ngakho inkanyezi exhume indawo engathathi hlangothi yejeneretha isethelwe ukuhoxiswa futhi ingamiswa ngokuqondile lapho kudingeka.Isistimu ye-10kV iwuhlelo oluncane lwamanje lomhlaba, futhi indawo engathathi hlangothi ngokuvamile ayigxili noma isekelwe ngenxa yokumelana nokuphansi.Ngakho-ke, uma kuqhathaniswa namayunithi ane-voltage ephansi, amayunithi angu-10kV adinga ukungezwa kwemishini yokusabalalisa amaphuzu angathathi hlangothi njengamakhabethe okumelana namakhabethe okuxhumana.
3. Umehluko wezindlela zokuvikela
Amasethi akhiqiza amandla kagesi aphezulu ngokuvamile adinga ukufakwa kokuvikela kwamanje kwekhefu elisheshayo, ukuvikelwa kokulayishwa ngokweqile, ukuvikela indawo ephansi, njll. Uma ukuzwela kwamanje kokuvikela ikhefu okusheshayo kungahlangabezani nezimfuneko, ukuvikelwa komehluko we-longitudinal kungafakwa.
Uma iphutha lesisekelo lenzeka ekusebenzeni kwesethi ye-generator yamandla aphezulu, ibeka ingozi enkulu yokuphepha kubasebenzi kanye nemishini, ngakho-ke kuyadingeka ukusetha ukuvikelwa kwephutha lesisekelo.
Iphoyinti elingathathi hlangothi lejeneretha lisekelwe nge-resistor.Uma kwenzeka iphutha lesigaba esisodwa sokumisa phansi, iphutha lamanje eligeleza endaweni emaphakathi lingatholwa, futhi ukuvikelwa kokukhubeka noma ukuvala shaqa kungafinyelelwa ngokuvikelwa kwe-relay.Iphoyinti elingathathi hlangothi lejeneretha lisekelwe nge-resistor, engakhawulela okwamanje iphutha ngaphakathi kwejika elivumelekile lomonakalo we-generator, futhi i-generator ingasebenza ngamaphutha.Ngokumelana nokubekwa phansi, amaphutha aphansi angatholwa ngokuphumelelayo futhi izenzo zokuvikela i-relay zingaqhutshwa.Uma kuqhathaniswa namayunithi ane-voltage ephansi, amasethi ejeneretha ane-voltage ephezulu adinga ukungezwa kwemishini yokusabalalisa amaphuzu angathathi hlangothi njengamakhabhinethi okumelana namakhabethe okuxhumana.
Uma kunesidingo, ukuvikela okuhlukile kufanele kufakwe kumasethi ejeneretha ane-voltage ephezulu.
Nikeza ukuvikelwa kwamanje okuhlukile kwezigaba ezintathu ku-stator winding of the generator.Ngokufaka ama-transformer amanje kumatheminali amabili aphumayo ekhoyili ngayinye kujeneretha, umehluko wamanje phakathi kwamatheminali angenayo naphumayo ekhoyili uyalinganiswa ukuze kutholakale ukuthi ikhoyili injani.Uma isifunda esifushane noma isisekelo senzeka kunoma yiziphi izigaba ezimbili noma ezintathu, iphutha lamanje lingatholwa kuwo womabili ama-transformer, ngaleyo ndlela ukushayela ukuvikelwa.
4. Umehluko kumakhebuli okukhiphayo
Ngaphansi kweleveli yomthamo ofanayo, ububanzi bekhebula lokuphumayo lamayunithi anamandla amakhulu buncane kakhulu kunalelo lamayunithi anamandla kagesi aphansi, ngakho-ke izidingo zomsebenzi wesikhala zamashaneli aphumayo ziphansi.
5. Umehluko Ezinhlelweni Zokulawula Iyunithi
Isistimu yokulawula iyunithi yamayunithi ane-voltage ephansi ngokuvamile ingahlanganiswa ohlangothini olulodwa lwengxenye yejeneretha emzimbeni womshini, kuyilapho amayunithi anamandla kagesi aphezulu ngokuvamile adinga ibhokisi lokulawula iyunithi elizimele ukuze lihlelwe ngokwehlukana neyunithi ngenxa yezinkinga zokuphazanyiswa kwesignali.
6. Umehluko ezidingweni zesondlo
Izidingo zokugcinwa kwamayunithi akhiqiza amandla kagesi aphezulu ezicini ezahlukahlukene ezifana nesistimu yesekethe kawoyela kanye nesistimu yokungenisa umoya ne-exhaust zilingana nalezo zamayunithi ane-voltage ephansi, kodwa ukusatshalaliswa kwamandla kwamayunithi kuwuhlelo lwamandla kagesi aphezulu, kanye nezisebenzi zokunakekela. kudingeka ifakwe izimvume zokusebenza ezinamandla kagesi.
