1. Kapangidwe ka switch cabinet:
Switchgear idzakwaniritsa zofunikira za GB3906-1991 "3-35 kV AC Metal-enclosed Switchgear". Amapangidwa ndi nduna ndi chophwanyira dera, ndipo ali ndi ntchito monga mawaya olowera ndi otuluka pamwamba, mawaya olowera ndi otuluka, ndi kulumikizana kwa basi. Kabati imapangidwa ndi chipolopolo, zida zamagetsi (kuphatikiza ma insulators), njira zosiyanasiyana, ma terminals achiwiri ndi kulumikizana.
★ Zida za Cabinet:
1) Cold adagulung'undisa zitsulo mbale kapena ngodya zitsulo (zowotcherera nduna);
2) Al-Zn wokutidwa zitsulo pepala kapena kanasonkhezereka zitsulo (zogwiritsidwa ntchito kusonkhanitsa makabati).
3) Chitsulo chosapanga dzimbiri (chopanda maginito).
4) Aluminiyamu mbale ((yopanda maginito).
★ Chigawo chogwirira ntchito cha nduna:
1) Chipinda chachikulu chabasi (nthawi zambiri, mawonekedwe akulu a basi ali ndi magawo awiri: "pini" mawonekedwe kapena "1" mawonekedwe.
2) Chipinda chophwanyira dera
3) Chipinda cha chingwe
4) Relay ndi chipinda cha zida
5) Chipinda chaching'ono cha basi pamwamba pa nduna
6) Chipinda chomaliza chachiwiri
★ Zida zamagetsi mu kabati:

Kusintha kwa katundu [monga FN26-12(L), FN16-12(Z)]
High-voltage single-phase shunt capacitor [monga: BFF12-30-1] etc.
1.2. Zigawo zazikulu zachiwiri zomwe zimagwiritsidwa ntchito mu nduna (yomwe imadziwikanso kuti zida zachiwiri kapena zida zothandizira, zimatanthawuza zida zotsika kwambiri zomwe zimayang'anira, kuwongolera, kuyeza, kusintha ndi kuteteza zida zoyambira), zida zodziwika bwino ndi izi:
1.Relay 2. Magetsi mita 3. Ammeter 4. Voltage mita 5. Mphamvu yamagetsi 6. Mphamvu yamagetsi 7. Miyendo yafupipafupi 8. Fuse 9. Kusintha kwa mpweya 10. Kusintha kosintha 11. Nyali yamagetsi 12. Kukaniza 13. Button 14 . Microcomputer Integrated chitetezo chipangizo ndi zina zotero.
2. Gulu la makabati osinthira ma voltage apamwamba:
2.1. Malinga ndi njira yokhazikitsira chophwanyira dera, chimagawidwa kukhala mtundu wochotsa (mtundu wa ngolo) ndi mtundu wokhazikika.
(1) Mtundu wochotsedwa kapena ngolo yamanja (yosonyezedwa ndi Y): Zimatanthawuza kuti zida zazikulu zamagetsi (monga zowononga dera) mu kabati zimayikidwa pa ngolo yomwe imatha kuchotsedwa, chifukwa makabati amangolowa amatha kusinthana bwino. bwino kwambiri kudalirika kwa magetsi. Mitundu ya ngolo zomwe zimagwiritsidwa ntchito nthawi zambiri ndi izi: ngolo zodzipatula, ngolo zoyezera metering, ngolo zapamanja zophwanyira dera, ngolo zamanja za PT, ngolo zonyamula pamanja ndi ngolo zomwe zimagwiritsidwa ntchito, monga KYN28A-12.
(2) Mtundu wosasunthika (wosonyezedwa ndi G): Umasonyeza kuti zigawo zonse zamagetsi (monga zowononga dera kapena zosinthira katundu, ndi zina zotero) mu nduna zimayikidwa mokhazikika, ndipo makabati osinthika okhazikika ndi osavuta komanso otsika mtengo, monga XGN2-10 , GG-1A ndi zina.
2.2. Amagawidwa m'nyumba ndi kunja malinga ndi malo oyika
(1) Zogwiritsidwa ntchito m'nyumba (zosonyezedwa ndi N); zikutanthauza kuti ikhoza kukhazikitsidwa ndikugwiritsidwa ntchito m'nyumba, monga KYN28A-12 ndi makabati ena osinthira;
(2) Zogwiritsidwa ntchito panja (zosonyezedwa ndi W); zikutanthauza kuti ikhoza kukhazikitsidwa ndi kugwiritsidwa ntchito panja, monga XLW ndi makabati ena osinthira.
3. Malinga ndi kamangidwe ka nduna, akhoza kugawidwa m'magulu anayi: zitsulo-zotsekedwa zida switchgear, zitsulo-otsekeredwa m'chipinda switchgear, zitsulo-otsekeredwa bokosi mtundu switchgear, ndi lotseguka-mtundu switchgear.
(1) Zitsulo zotsekedwa ndi zida zachitsulo (zosonyezedwa ndi chilembo K) Zigawo zazikuluzikulu (monga zowononga dera, zosinthira, mipiringidzo ya mabasi, ndi zina zotero) zimayikidwa muzitsulo zazitsulo zazitsulo zokhazikika zolekanitsidwa ndi magawo azitsulo. Sinthani zida. Monga KYN28A-12 mtundu mkulu voteji lophimba nduna.
(2) Chitsulo chotsekedwa ndi zitsulo (chosonyezedwa ndi chilembo J) chimafanana ndi zida zachitsulo zotsekedwa ndizitsulo, ndipo zigawo zake zazikulu zamagetsi zimayikidwanso m'zipinda zosiyana, koma zimakhala ndi chitetezo chimodzi kapena kuposerapo. kugawa. Monga JYN2-12 mtundu mkulu voteji lophimba nduna.
(3) Chophimba chachitsulo chotsekedwa ndi bokosi (chosonyezedwa ndi chilembo X) Chigoba cha switchgear ndizitsulo zotsekedwa ndizitsulo. Monga XGN2-12 high voltage switch cabinet.
(4) Tsegulani switchgear, palibe chofunikira pamlingo wachitetezo, gawo la chipolopolo ndi switchgear yotseguka. Monga GG-1A (F) high voltage switch cabinet
