Iimeko zoyilo
Iimeko zamandla
Ngokwenani lombane elifunyenwe kule projekthi, inkampani yethu iceba ukuxhobisa i-18 MW iiseti zejenereyitha yegesi+6 iiseti ze-booster kunye ne-transformer skid (i-tpye equlathe i-container, ukunyusa ukuya kwi-10 kV) +1 iseti ye-10 kV sub-section post +1 iseti ye-step-down transformer skid. Ngokunika iiseti ezili-18 ze-1MWgas generator ezibekwe kwii-6 box type transformer skids ngokulandelanayo, i-400 V voltage inyuswa ukuya kwi-10 kV ize idityaniswe kwi-10 kV sub-section post, kwaye i-sub-section post inika amandla kwi-friji compressor. Kwangaxeshanye, inxalenye yamandla ombane iphuma kwi-step-down transformer skid, amandla ombane angama-400V asasazwa yi-step-down transformer skid.
Ngokwendlela ombane ngayo lo msebenzi, iiseti ezi-1 ~ 2 zeeseti zejenereyitha yegesi eziyi-1MW (ezaziwa ngokuba I-genset yegesi eyi-1000kw） Ingacinywa, enokutshintshwa ukuze isetyenziswe ukugcinwa kwejenereyitha okulandelayoKucetyiswa iseti yenkqubo yolawulo lwesitishi esikude kule projekthi, enokujonga ukusebenza okuthe ngqo kweseti yejenereyitha kwigumbi lolawulo eliphakathi. Iseti yegesi yolwelo lwegesi isetyenziselwa ukusetyenziswa kobushushu obungafunekiyo, kwaye iyunithi ye-1MW ixhotyiswe nge-DN300 flue gas header kunye ne-flange.
Umbane omnye osebenza ngamandla aphezulu ombane obonelelwa ngumsebenzisi yi-10KV±5% 50HZ±0.5HZ, inkqubo yezintambo ezintathu ezinamanqanaba amathathu, kwaye indawo engathathi cala ayixhonywanga. Kuqaliswa ukungcwatywa ngokuthe ngqo kweentambo eziphezulu zombane ezixhonyiweyo.
Ububanzi boyilo
Iqela B linoxanduva lokuyila isikhululo esingaphantsi se-10KV/0.4KV kunye nenkqubo yokubonelela ngombane kunye nokusasazwa kwesityalo sokunyibilikisa ulwelo (kunye nentloko yenqwaba yokufumana umbane yekhabhinethi engenayo ye-10KV njengomda), linoxanduva lokuyila imizobo yenkqubo yombane enevolthi ephezulu nephantsi, imizobo yeskimu yokulawula umbane, kunye nomzobo wesiphelo, umzobo woyilo lwesalathiso sezixhobo zombane ezinevolthi ephezulu nephantsi, kunye noyilo lwebhokisi yokusebenza yendawo (ikholamu). Ukusasazwa kombane wesixhobo sombane esipheleleyo, unikezelo lombane lwepompo yombane ephambili yenkqubo yokukhusela umlilo, ukukhanya koluntu kwesityalo sonke, inkqubo yokukhanyisa isakhiwo, unikezelo lombane olungxamisekileyo lweejenereyitha zedizili, kunye neebhokisi zokusasazwa kolondolozo (iikhabhinethi) azikho ngaphakathi kolu yilo.
Imigaqo yoyilo nokukhetha
(1) Izixhobo zokulawula ze-elektroniki zale ndawo yokunyibilikisa ulwelo mazizame ukuba zithembeke, zikhuselekile, ziphucuke kwaye zibe lula ukuzisebenzisa ngokwesiseko sokuhlangabezana neemeko zoyilo kunye neemfuno zenkqubo.
(2) Ulawulo, umlinganiselo, ukhuseleko kunye nomqondiso wazo zonke iimoto nezixhobo zombane kufuneka zimiselwe ngokuhambelana nemigaqo yesizwe efanelekileyo.
(3) Inkqubo ye-0.4KV efektri iyilwe njengesekethe ephindwe kabini.
(4) Zonke izixhobo zombane zenkqubo zixhotyiswe ngeebhokisi zolawulo lokusebenza lwendawo (iikhabhinethi). Umgangatho wokhuseleko lwezixhobo zolawulo lombane lwendawo olungenakuqhuma kwiindawo ezingenakuqhuma luyilwe ngokwe-DⅡBT4, kwaye umgangatho walo wokhuseleko yi-IP65; umgangatho wokhuseleko lwangaphandle lwezixhobo zolawulo lombane kwiindawo ezingenakuqhuma yi-IP54 Design, umgangatho wokhuseleko lwezixhobo zolawulo lwe-elektroniki zangaphakathi luyilwe ngokwe-IP30.
(5) Xa iimoto eziphezulu nezisezantsi ziqaliswa, i-voltage yebhasi mayingadluli kwi-85% ye-voltage elinganisiweyo. Ngenxa yesi sizathu, iimoto ezine-voltage ephantsi ezinamandla alinganisiweyo angama-75KW nangaphezulu kufuneka ziqale nge-starter ethambileyo; i-motor ephambili ye-refrigerant compressor isebenzisa isixhobo sokuqalisa esiqinileyo esinombane ophezulu.
(6) Inkqubo ye-high-voltage isebenzisa isixhobo sokukhusela esihlanganisiweyo se-microcomputer ukuze siphumeze imisebenzi efana nokukhusela i-relay kunye ne-metering.
(7) Ukusebenza, ukhuseleko kunye namandla esignali yeswitshi ye-high-voltage switchgear isebenzisa umbane we-DC we-DC220V, ovela kwiscreen se-DC sebhetri ye-lead-acid engenasondlo, kwaye umbane we-DC wabelwana ngawo nenkqubo ye-10KV.
(8) Imeko yokusebenza kwezixhobo zombane zesixhobo sonke sokunyibilikisa ulwelo kunye nesignali yangoku yemoto engama-30KW nangaphezulu zingena kwinkqubo ye-DCS ukuze ziboniswe, kwaye zonke izixhobo zombane zezixhobo zenkqubo zingaqaliswa kwaye zimiswe kwi-DCS kwigumbi lolawulo eliphakathi, kwaye zingaqaliswa kwaye zimiswe kwindawo ethile. Amaqhosha okumisa ngexesha likaxakeka kwiicompressor zefriji, iicompressor zegesi yokuphakelwa, iimpompo zamanzi ezijikelezayo, njl. Zisetwa kwigumbi lolawulo eliphakathi.
(9) Isixhobo sokukhusela esibanzi se-microcomputer senkqubo ye-medium voltage sisasazwa kwaye sifakwe kwikhabhathi nganye yeswitshi, kwaye kumiselwe inkqubo yokujonga imvelaphi ye-microcomputer. Inkqubo yokujonga imvelaphi yenkqubo ye-10KV yabelwana ngayo nenkqubo yokujonga imvelaphi ye-35KV, kwaye akukho mfuneko yokuseta okwahlukileyo. Qaphela ukujonga iiparameter zokusetyenziswa kwamandla kwisityalo sokunyibilikisa ulwelo, ukujonga umgangatho wombane wegridi, ulawulo olukude lwezixhobo, ukulinganisa kunye nemisebenzi ye-alamu, ulawulo lweengxelo, uhlalutyo lweendlela, izibalo, kunye nokurekhodwa kwazo zonke iiparameter zombane zesityalo sokunyibilikisa ulwelo.
(10) Inkqubo ye-10KV high-voltage ixhotyiswe ngesixhobo sokubuyisela amandla esisebenzayo esisebenza ngamandla amakhulu ukuze yenze imbuyekezo yamandla asebenzayo kwizixhobo ze-high-voltage. Emva kwembuyekezo, amandla ebhasi angaphezulu kwe-0.95. Inkqubo ye-low-voltage ixhotyiswe ngesixhobo sokubuyisela amandla esisebenza ngokungaqhagamshelaniyo ukuze yenze imbuyekezo yamandla asebenzayo kwibhasi ye-380V. Emva kwembuyekezo, amandla ebhasi angaphezulu kwe-0.95.
