2. Dongosolo lalikulu la dera
Dongosolo lalikulu la dera la chipangizochi lili ndi magulu 32 ndi mafotokozedwe 118, kupatula ma scheme ndi ma specifications ochokera ku kusintha kwa kuwongolera ndi kuteteza dera lothandizira. Limaphatikizapo zosowa za kupanga magetsi, magetsi ndi ogwiritsa ntchito ena amphamvu. Mphamvu yogwira ntchito yovoteledwa ndi 4000A, yomwe ndi yoyenera kusankha ma transformer ogawa pansi pa 2500kVA. Kuphatikiza apo, kabati yolipirira capacitor idapangidwa kuti ikwaniritse zosowa za magetsi ndi kukonza mphamvu. Poganizira kufunika kwa ndalama zambiri, kabati ya reactor idapangidwa.
Ndemanga:
①DW914 ndiye chothyola mawaya chachikulu, ndipo mawaya ena a mawaya omwe ali ndi magwiridwe antchito apamwamba kapena RDSW6 (RDW1), mndandanda wa FM nawonso angasankhidwe.
②01, 02, 04 mayankho ngati chingwe cha PE N chikufunika kulowa mu kabati yamagetsi, m'lifupi mwa kabatiyo muyenera kukhala ndi kukula m'mabulaketi.
③SDL ndi SDH ndi ma transformer apadera amagetsi a makabati a GCS.
3. Chiwembu chothandizira cha dera
Pali ma circuit scheme 120 othandizira mu GCS Auxiliary Circuit Atas, omwe amagawidwa m'mavoliyumu awiri. Voliyumu yoyamba "AC Operation Part" imagawidwa m'ma scheme 63, ndipo voliyumu yachiwiri "DC Operation Part" imagawidwa m'ma scheme 57.
Dongosolo lothandizira la gawo logwira ntchito la DC limagwiritsidwa ntchito makamaka mu dongosolo la magetsi otsika (station) la chomera chamagetsi ndi malo osinthira magetsi. Ndiloyenera dongosolo la magetsi otsika a chipangizocho lomwe lili ndi mphamvu ya 200MW ndi pansi pake ndi 300MW ndi pamwamba pake, komanso njira yowongolera yonse ya chingwe chogwirira ntchito (chosungira) chamagetsi cholowera, chingwe chodyetsa magetsi ndi chingwe chodyetsa magalimoto.
Chida chothandizira cha gawo la AC chimagwiritsidwa ntchito makamaka pamakina otsika amagetsi m'mafakitale, migodi, mabizinesi ndi nyumba zazitali. Pali njira 6 zophatikizika zoyenera kuwongolera magwiridwe antchito amagetsi awiri, ndipo pali ma circuit owongolera monga opareshoni yamagetsi yolumikizira yokha komanso yodzibwezeretsa yokha, zomwe zingagwiritsidwe ntchito mwachindunji pakupanga kwaukadaulo.
Mphamvu yowongolera ya DC ndi Dc 220V kapena 110v, ndipo mphamvu yowongolera ya AC ndi AC 380V kapena 220V. Mphamvu yowongolera ya 220v imachokera ku mphamvu yowongolera ya anthu onse yoperekedwa ndi transformer yapadera yowongolera mu kabati. Mphamvu yowongolera ya anthu onse imagwiritsa ntchito njira yosazunguliridwa kuti ilamulire transformer, ndipo mphamvu ya 24V imasungidwa kuti igwiritse ntchito nyali zamagetsi zofooka. Kuti mudziwe malo oyika mita ya watt-hour, njira yoyambira ya voltage ndi zofunikira zina zoyika ndi kugwiritsa ntchito, chonde onani "Malangizo Ophatikiza" a chithunzi chothandizira cha dera.
4. Basi
Pofuna kulimbitsa kukhazikika kwa kutentha kwa bala la basi ndikukweza kutentha kwa malo olumikizirana, mipiringidzo ya mkuwa ya TMY-T2 imagwiritsidwa ntchito pazida zonse. Zigawo zolumikizira za mipiringidzo ya mkuwa ziyenera kukhala zophimbidwa ndi tin. Mipiringidzo ya mkuwa yophimbidwa ndi tin ndi yolimbikitsidwa, ndipo mipiringidzo ya mkuwa yophimbidwa ndi siliva ingagwiritsidwenso ntchito.
a. Mulingo wopingasa wa basi
Chipinda cha basi chili m'chipinda cha basi kumbuyo kwa kabati, ndipo zigawo ziwiri zapamwamba ndi zapansi zimakonzedwa kuti zigwirizane ndi 3150A ndi kupitirira apo, ndipo gawo limodzi limakonzedwa kuti zigwirizane ndi 2500A ndi kupitirira apo. Gawo lililonse limapangidwa ndi mabasi anayi kapena awiri, zomwe zimathandizira kwambiri mphamvu ya short-circuit ya basi.
Kusankhidwa kwa busbar yopingasa ya chipangizochi kwawonetsedwa mu Gome 3.
| Yoyesedwa panopa (A) (Table 3) | Mafotokozedwe a Busbar |
| 630, 1250 | 2 (50×5) |

b. Malo oimika basi
Busbar yoyimirira yomwe imagwiritsidwa ntchito pa drawer imagwiritsa ntchito busbar yolimba yooneka ngati "L". Mafotokozedwe a busbar yooneka ngati L (mm): (kutalika x makulidwe)+ (pansi x makulidwe) (50 x 5)+ (30 x 5) Mphamvu yoyesedwa 100A.
c. Basi lopanda nthaka
Gwiritsani ntchito zitsulo zolimba zamkuwa. Kudzera mu waya wopingasa wopanda nthaka (PEN) kapena waya wopingasa + wopanda nthaka (PE + N), tsatanetsatane wa zinthu zawonetsedwa mu Gome 4.
| Gawo la woyendetsa magawo opingasa gawo lililonse (mm²) (Table 4) | Sankhani gawo la waya la PE (N) （mm²） |
| 500-720 | 40×5 |
| 1200 | 60×6 |
| >1200 | 60×10 |
* Mafotokozedwe a mawaya oimirira a PEN kapena mawaya a PE + N mu chipangizocho ndi 40 x 5.
5. Kusankha zida zamagetsi
Zipangizozi zimasankha makamaka zida zamagetsi zokhala ndi chizindikiro chapamwamba cha magwiridwe antchito komanso ukadaulo wochokera kunja, zomwe zimatha kupangidwa mochuluka ku China.
a. Chosinthira chachikulu
Pa ma switch a 630A ndi apamwamba kuposa apa, kusankha kwakukulu ndi mndandanda wa DW914, ndipo mndandanda wa RDSW6 (RDW1), DW40, DW48, mndandanda wa AE, mndandanda wa 3WE kapena RDW17 ungagwiritsidwenso ntchito. Ngati pakufunika, mndandanda wa M kapena mndandanda wa F wotumizidwa kunja ungagwiritsidwenso ntchito.
b.Pa ma feeder a 630A ndi pansi ndi ma switch owongolera mota, makamaka posankha mndandanda wa RDM949 ndi mndandanda wa RDM1 MCCB, ndipo angagwiritsenso ntchito NZM Series ndi TM30 Series MCCB.
c.AC contactor, makamaka kusankha CJX8 mndandanda, CJX2 (RDC6) mndandanda, CJX1 mndandanda contactors ndi ma relay awo ofanana kutentha ndi njira interlocking.
d. Ma transformer onse amakono amagwiritsa ntchito mndandanda wa SDH, mndandanda wa SDL ndi mndandanda wa SDL1 womwe umayang'aniridwa ndi Senyuan Electric Co., Ltd.
e.Fuse imasankha cholumikizira cha HH15 series knife-fuse ndi NT00 series yokhala ndi mphamvu zambiri zosweka.
f. Pofuna kukonza kukhazikika kwa mphamvu ya dera lalikulu, cholumikizira chapadera cha CMJ bus ndi chithandizo choteteza kutentha cha mndandanda wa GCS chapangidwa. Ndi thermoplastic yopangidwa ndi zinthu zophatikizana zolimba kwambiri zoletsa moto, zomwe zimakhala ndi mphamvu zambiri zoteteza kutentha, magwiridwe antchito abwino odzizimitsa okha komanso kapangidwe kake kapadera. Ndikofunikira kusintha chipika chomangira, chipikacho kuti chigwirizane ndi zofunikira zosiyanasiyana.ya basi.
Kuti achepetse kukwera kwa kutentha kwa spacer, cholumikizira ndi mutu wamagetsi wa chipangizo chogwirira ntchito, adaputala yapadera ya kabati ya GCS idapangidwa. Poyerekeza ndi zinthu zomwezo, mphamvu ya kutentha ya adaputala imawonjezeka ndipo kukwera kwa kutentha kumachepa.
Ngati dipatimenti yopanga zinthu isankha zida zatsopano zamagetsi zomwe zimagwira ntchito bwino komanso ukadaulo wapamwamba kwambiri malinga ndi zosowa za ogwiritsa ntchito, chifukwa makabati a GCS ali ndi magwiridwe antchito abwino, sizingayambitse mavuto popanga ndi kukhazikitsa chifukwa chosintha zida zamagetsi.
1. Chimango chachikulu cha chipangizocho chimagwiritsa ntchito chitsulo cha gawo la 8MF, ndipo chimangocho chimagwiritsa ntchito mitundu iwiri ya kapangidwe kake: kuphatikiza ndi kuwotcherera pang'ono. Pali mabowo a modulus oyika E = 20mm pa chimango chachikulu.
2. Chipinda chilichonse chogwirira ntchito cha chipangizochi chimalekanitsidwa mosamala, ndipo zipindazo zimagawidwa makamaka m'chipinda chogwirira ntchito, chipinda cha basi ndi chipinda chamagetsi. Ntchito za chipangizo chilichonse ndizodziyimira pawokha.
3. Kukula kwa kabati ya chipangizochi kuli monga momwe kwasonyezedwera patebulo
