Mikhalidwe ya kapangidwe
Mikhalidwe yamagetsi
Malinga ndi kuchuluka kwa magetsi omwe akugwiritsidwa ntchito pa ntchitoyi, kampani yathu ikukonzekera kuyika magetsi okwana 18 MW ma jenereta a gasi+6 seti ya booster ndi transformer skid (yokhala ndi container tpye, kuti iwonjezere kufika pa 10 kV) + seti imodzi ya 10 kV sub-section post + seti imodzi ya step-down transformer skid. Popereka seti 18 ya jenereta ya 1MWgas yoyikidwa ku 6 box type transformer skids motsatana, voltage ya 400 V imakwezedwa kufika pa 10 kV kenako imagwirizanitsidwa ndi 10 kV sub-section post, ndipo sub-section post imapereka mphamvu ku compressor yoziziritsira. Nthawi yomweyo, gawo la mphamvu yamagetsi limatuluka kupita ku step-down transformer skid, mphamvu yamagetsi ya 400V imagawidwa ndi step-down transformer skid.
Malinga ndi mphamvu yeniyeni ya polojekitiyi, seti 1 ~ 2 ya jenereta ya gasi ya 1MW (amadziwanso kuti jenereta ya gasi ya 1000kw） ikhoza kuzimitsidwa, yomwe ingasinthidwe kuti igwiritsidwe ntchito mu kukonza jenereta pambuyo pake. Pulogalamuyo imalimbikitsa kugwiritsa ntchito makina owongolera magetsi akutali, omwe amatha kuwona momwe jenereta imagwirira ntchito m'chipinda chowongolera chapakati. Mpweya wofewa wa jenereta ya gasi umagwiritsidwa ntchito potenthetsera zinyalala, ndipo chipangizo cha 1MW chili ndi mutu wa gasi wofewa wa DN300 ndi flange.
Mphamvu imodzi yamagetsi amphamvu kwambiri yomwe wogwiritsa ntchito amapereka ndi 10KV±5% 50HZ±0.5HZ, makina atatu a waya, ndipo mfundo yopanda malire siili pansi. Kuyika mwachindunji zingwe zamphamvu zamagetsi amphamvu kumayambitsidwa.
Chiwembu cha kapangidwe
Gulu B lili ndi udindo wopanga malo osinthira magetsi a 10KV/0.4KV ndi makina operekera magetsi ndi kugawa magetsi a chomera chosungunula madzi (ndi mutu wolandira magetsi wa kabati yolowera ya 10KV ngati malire), limayang'anira kapangidwe ka ma diagram amagetsi amagetsi okwera ndi otsika, ma diagram owongolera magetsi, ndi chithunzi cha Terminal, chithunzi chofotokozera zida zamagetsi zamagetsi okwera ndi otsika, ndi kapangidwe ka bokosi logwirira ntchito (mzere). Kugawa mphamvu kwa malo onse ogwiritsira ntchito magetsi, magetsi a pampu yayikulu yamagetsi ya makina oteteza moto, magetsi a anthu onse a fakitale yonse, makina owunikira nyumba, magetsi adzidzidzi a jenereta za dizilo, ndi mabokosi ogawa magetsi (makabati) sizili mkati mwa kapangidwe kameneka.
Mfundo zopangira ndi kusankha
(1) Zipangizo zamagetsi zowongolera za fakitale iyi yothira madzi ziyenera kuyesetsa kukhala zodalirika, zotetezeka, zapamwamba komanso zosavuta kugwiritsa ntchito poganizira zofunikira pakupanga ndi zofunikira pakupanga.
(2) Kulamulira, kuyeza, kuteteza ndi chizindikiro cha injini zonse ndi zida zamagetsi ziyenera kukhazikitsidwa motsatira malamulo oyenera a dziko.
(3) Dongosolo la 0.4KV lomwe lili mufakitale lapangidwa ngati ma double circuit.
(4) Zipangizo zonse zamagetsi zogwirira ntchito zili ndi mabokosi owongolera ntchito zakomweko (makabati). Gawo losaphulika la zida zamagetsi zakomweko m'malo osaphulika lapangidwa molingana ndi DⅡBT4, ndipo gawo lake loteteza ndi IP65; gawo loteteza panja la zida zamagetsi zowongolera m'malo osaphulika ndi IP54 Design, gawo loteteza zida zamagetsi zowongolera zamkati lapangidwa molingana ndi IP30.
(5) Pamene ma mota okwera ndi otsika ayambitsidwa, magetsi a basi ayenera kufika osachepera 85% ya magetsi oyesedwa. Pachifukwa ichi, ma mota otsika mphamvu okhala ndi mphamvu yoyesedwa ya 75KW ndi kupitirira apo amafunika kuyamba ndi choyambira chofewa; mota yayikulu ya compressor ya refrigerant imagwiritsa ntchito chipangizo choyambira cholimba champhamvu champhamvu.
(6) Dongosolo lamagetsi amphamvu kwambiri limagwiritsa ntchito chipangizo choteteza cholumikizidwa ndi kompyuta yaying'ono kuti chigwire ntchito monga chitetezo cha relay ndi metering.
(7) Mphamvu yogwira ntchito, yoteteza komanso yowonetsa chizindikiro cha switchgear yamagetsi amphamvu imagwiritsa ntchito mphamvu ya DC ya DC220V, yomwe imachokera ku batire ya DC yopanda lead-acid yosamalira, ndipo mphamvu ya DC imagawidwa ndi makina a 10KV.
(8) Momwe zida zamagetsi zogwiritsira ntchito pazida zonse zoyeretsera madzi zimagwirira ntchito komanso chizindikiro chamagetsi cha mota ya 30KW ndi kupitirira apo zimalowa mu dongosolo la DCS kuti ziwonetsedwe, ndipo zida zonse zamagetsi za zida zoyendetsera ntchito zimatha kuyatsidwa ndikuyimitsidwa pa DCS mchipinda chowongolera chapakati, komanso zimatha kuyatsidwa ndikuyimitsidwa kwanuko. Mabatani oyimitsa mwadzidzidzi a ma compressor oziziritsa, ma compressor a gasi odyetsa, mapampu amadzi ozungulira, ndi zina zotero. Amayikidwa mchipinda chowongolera chapakati.
(9) Chipangizo chotetezera cha microcomputer cha medium voltage system chimagawidwa ndikuyikidwa pa kabati iliyonse yosinthira, ndipo makina owunikira kumbuyo kwa microcomputer amakhazikitsidwa. Makina owunikira kumbuyo kwa system ya 10KV amagawidwa ndi makina owunikira kumbuyo a 35KV, ndipo palibe kukhazikitsidwa kwina komwe kumafunika. Dziwani kuwunika kwa magawo ogwiritsira ntchito mphamvu pa chomera chosungunula madzi, kuwunika kwabwino kwa magetsi a gridi, kuwongolera kutali kwa zida, kuyeza ndi ntchito za alamu, kuyang'anira malipoti, kusanthula zomwe zikuchitika, ziwerengero, ndi kujambula magawo onse amagetsi a chomera chosungunula madzi.
(10) Dongosolo lamagetsi amphamvu la 10KV lili ndi chipangizo cholipirira mphamvu chosinthika chomwe chimagwira ntchito pakati kuti chigwire ntchito yolipirira mphamvu yosinthika pazida zamagetsi amphamvu. Pambuyo polipirira, mphamvu ya basi imakhala yoposa 0.95. Dongosolo lamagetsi otsika lili ndi chipangizo cholipirira mphamvu chosinthika chosakhudzana kuti chigwire ntchito yolipirira mphamvu yosinthika pa basi ya 380V. Pambuyo polipirira, mphamvu ya basi imakhala yoposa 0.95.
