Ntchito ndi ntchito ya mkulu voteji wathunthu zida

Zipangizo zokhala ndi magetsi okwera kwambiri (kabati yogawa magetsi okwera kwambiri) imatanthawuza zida zosinthira zamkati ndi zakunja za AC zomwe zimagwira ntchito pamakina amagetsi okhala ndi 3kV ndi pamwamba ndi ma frequency a 50Hz ndi pansi.Amagwiritsidwa ntchito makamaka poyang'anira ndi kuteteza machitidwe a mphamvu (kuphatikizapo magetsi, malo opangira magetsi, mizere yotumizira ndi kugawa, makampani ogulitsa mafakitale ndi migodi, etc.) Pamene mzerewu ukulephera, gawo lolakwika limachotsedwa mwamsanga ku gridi yamagetsi, kuti zitsimikizidwe. ntchito yachibadwa ya gawo lopanda vuto la gridi yamagetsi ndi chitetezo cha zipangizo ndi ntchito ndi ogwira ntchito yokonza.Chifukwa chake, zida zathunthu zamagetsi apamwamba ndizofunikira kwambiri zotumizira ndi kugawa mphamvu zamagetsi, ndipo ntchito yake yotetezeka komanso yodalirika ndiyofunikira kwambiri pakugwiritsa ntchito bwino mphamvu zamagetsi.

Zida zonse za High-voltage zimatha kugawidwa m'magulu awiri:
(1) Zigawo ndi zophatikizira zake: kuphatikiza zowononga madera, zosinthira zodzipatula, masiwichi apansi, zotsekera, zotchingira dera, zosinthira katundu, zolumikizira, ma fuse ndi zinthu zomwe zili pamwambazi Kuphatikizana kophatikizira kosinthira-fuse, kuphatikiza-fuse (FC), kuphatikiza katundu, kudzipatula. kusintha, kusintha kwa fuse, kuphatikiza kotseguka, ndi zina.
(2) Complete seti ya zida: kuphatikiza zigawo pamwamba ndi osakaniza awo ndi zinthu zina magetsi (monga thiransifoma, thiransifoma panopa, voteji thiransifoma, capacitors, reactors, zomangira, mipiringidzo mabasi, polowera ndi kutulukira bushings, materminal chingwe ndi zigawo yachiwiri, etc.) kasinthidwe wololera, organically pamodzi zitsulo chatsekedwa chipolopolo, ndi mankhwala ndi ntchito ndi wathunthu ntchito.Monga zitsulo-zotsekeredwa switchgear (switchgear), gasi-insulated zitsulo-enclosed switchgear (GIS), ndi high-voltage/low-voltage prefabricated substations.
