Classification ntawm substations
Kev faib tawm ntawm substations: 1: Raws li kev faib tawm ntawm kev ua haujlwm, muaj xws li: kauj ruam-up substation, kauj ruam-down substation lossis hub substation, davhlau ya nyob twg substation, thiab lwm yam. substations. 3: Raws li cov qauv ntawm sab hauv tsev thiab sab nraum zoov substation, muaj: sab nraum zoov substation, sab hauv tsev substation. 4: Raws li thaj chaw, muaj: saum toj-hauv av substation thiab underground substation. [1] Cov khoom siv tseem ceeb muaj pes tsawg leeg thiab txoj kev sib txuas ntawm lub chaw nres tsheb yuav sib txawv raws li nws txoj haujlwm thiab ib puag ncig.
Lub ntsiab lus txhais tau teev tseg hauv lub teb chaws tus qauv GB50053-94" 10kv thiab hauv qab Substation Design Specification", raws li lub transformer installation qhov chaw thiab ib puag ncig, los ntawm sab hauv thiab sab nraum zoov, sab hauv tsev thiab sab nraum zoov, lub substation yog txhais. raws li:
Substation:" Lub zog AC ntawm 10 kV thiab hauv qab no yog hloov pauv los ntawm lub zog hloov hluav taws xob los muab lub zog rau cov khoom siv hluav taws xob." Lub substation yog qhov ua tau raws li qhov xav tau no.
Open-air substation: lub substation uas nws transformer yog nyob rau saum toj ntawm qhov chaw qhib;
Semi-sab nraum zoov substation: lub substation uas lub transformer yog nyob rau saum toj ntawm qhov qhib av, tab sis muaj ib lub ru tsev los yog overhang saum lub transformer;
Txuas nrog substation: ib lossis ob peb phab ntsa ntawm lub substation yog sib koom nrog cov phab ntsa ntawm lub tsev, thiab lub qhov rooj thiab qhov cua qhov rais ntawm chav tsev transformer qhib rau sab nraum lub tsev;
Substation nyob rau hauv lub rhiav: ib tug substation nyob rau hauv lub rhiav, thiab lub qhov rooj ntawm chav tsev transformer qhib rau hauv lub rhiav;
Independent substation: ib lub tsev ywj pheej;
Sab hauv tsev substation: lub ntsiab lus dav dav rau kev txuas nrog substations, ywj siab substations thiab substations hauv kev cob qhia;
Cov roj cia tank: ib qho chaw uas cov roj yuav tsis raug hlawv los ntawm cov khoom siv hluav taws kub hnyiab tom qab cov roj ntws hauv;
Cov chaw khaws roj: cov chaw uas tiv thaiv kom tsis txhob hlawv roj los ntawm kev nchuav.
Tsis tas li ntawd, lub teb chaws cov lus txhais ntawm lwm cov ntsiab lus suav nrog:
Terminal substation: Ib lub chaw nres tsheb sib cais ua ke yog thawj lub chaw nres tsheb nyob rau pem hauv ntej kawg ntawm tus neeg siv hluav taws xob lossis cov neeg siv. Cov hluav taws xob los ntawm lub substation tuaj yeem xa ncaj qha mus rau cov neeg siv khoom siv hluav taws xob yam tsis tas yuav mus dhau qhov kev hloov pauv dua. Nias. Feem ntau yog hais txog qhov kawg-theem substation uas tau nqis los ntawm 10kV mus rau 380V.
Ncej-mounted substation: Ib qho chaw sab nraum zoov tau nruab rau ntawm ib lossis ntau tus ncej.
Pre-installed substation (chaw nres tsheb): ua tiav cov cuab yeej ua ntej-ntsia thiab hom kev sim, feem ntau yog tsim los ntawm cov khoom siv hluav taws xob hluav taws xob loj, cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob tsawg, ua ke hauv ib lossis ob peb lub thawv. Kuj hu ua"box hloov" luv luv.
Piv txwv li: Hauv qee qhov chaw nyob deb nroog ntawm peb lub teb chaws, cov neeg nyob hauv siv hluav taws xob thiab siv ob tug ncej (lossis desktop) los tsim cov chaw hloov hluav taws xob. Qhov no tsis yog tsuas yog me me thiab yooj yim rau nruab" qhib-cua substation", tab sis kuj yog" ncej-mounted substation". "Substation" kuj yog "terminal substation".
