GKG mtundu general high-voltage switchgear kwa migodi ndi oyenera ntchito migodi malasha popanda mpweya, ngozi kuphulika fumbi malasha ndi zina zofananira mobisa mafakitale kupanga ndi madipatimenti magetsi monga migodi sanali malasha.Mtundu wa GKG general high-voltage switchgear for mining (pano umatchedwa switchgear ), womwe umagwiritsidwa ntchito kwambiri poyimitsa magalimoto obisala pansi pa gasi ndi fumbi la malasha mumgodi, msewu waukulu wolowera mpweya ndi chipinda chogawa mphamvu cha msewu waukulu wolowera mpweya.Monga AC 50Hz, voteji 7.2KV kapena 12KV zida zamagetsi zogawa mzere ukubwera, wodyetsa, chitetezo ndi kuwongolera ma motors apamwamba kwambiri, ma transfoma.Switchgear itha kugwiritsidwanso ntchito m'malo opangira migodi ya malasha ndi magetsi ndi njira zogawa m'mafakitale azitsulo ndi mankhwala.
Muyezo uwu ukugwirizana ndi GB/T12173-2008 "General Electrical Equipment for Mining", JB 8739-2015 "Flameproof High Voltage Power Distribution Chipangizo cha Migodi", GB3836.1-2010 "Chilengedwe Chophulika Gawo 1: Zofunikira Zonse Pazida", GB3836 .3-2010 "Zophulika Zophulika Gawo 3: Zida Zotetezedwa ndi Chitetezo Chowonjezereka" "e" ndi miyezo ina imapangidwa.Magawo aukadaulo ndi zofunikira za mulingo uwu ndizokhazikika, zatsatanetsatane komanso zogwira ntchito.

Zogulitsa ndi malo ogwirira ntchito

1. Switchgear imagonjetsa zofooka za switchgear yoyambirira.Makina osinthira amtundu wa ngolo yopangidwa ndi kampaniyo ali ndi ntchito zodzitchinjiriza kwathunthu, kudalirika kwambiri, komanso kukonza kosavuta komanso kosavuta.Kukula kochepa ndi kulemera kochepa.
2. Kabati yosinthira imapangidwa ndi kabati ndi ngolo yamanja.Chipindacho chimagawidwa m'chipinda cha ngolo, chipinda cha basi, chipinda cha chingwe, ndi chipinda cholandirirana ndi chogawa.Ngolo yamanja ili ndi malo awiri oyesera ndi ntchito.Chipinda cha ngolo yamanja chimasiyanitsidwa ndi chipinda cha chingwe ndi mbale yotchinga yosunthika, yomwe imakhala yabwino komanso yotetezeka panthawi yokonza.Kusinthana kwa ngolo yamanja ndi 100%, kuchepetsa nthawi yokonza ndikuwongolera mphamvu zamagetsi.Ngolo yapamanja yotsetsereka ndi yolondola komanso yosinthika kuwonetsetsa kuti ngoloyo sipatuka kulowa ndi kutuluka, ndipo njanji yolowera pamanja imayikidwa kuti pulagi yachiwiri ikhale yolondola komanso yodalirika.
3. Ntchito yoteteza switchgear, patatha zaka zogwiritsidwa ntchito m'migodi ya malasha, mankhwalawa amatha kukumana ndi njira zodzitetezera pazolinga zosiyanasiyana, zokhala ndi kutayikira, kuyang'anira kutchinjiriza, kutsika kwamagetsi, kuzungulira kwachidule, kupitilira kwamagetsi, komanso kugwiritsidwa ntchito ndi kuwongolera kwakutali, kulumikizana kwakutali, telemetry, ndi zina zotere. Chipangizo chodzitchinjiriza chodziwikiratu chikhoza kukhala ndi kachipangizo kakang'ono kamene kamateteza mzere wachitetezo.
Mndandanda wa chitetezo cha microcomputer migodi ndi kuyeza ndi kuwongolera zida zitha kusankhidwa.Dongosolo lachitetezo lili ndi mawonekedwe olumikizirana.Zidziwitso zonse zimatumizidwa kumayendedwe apamwamba kapena owongolera munthawi yeniyeni kudzera pa netiweki yolumikizirana."Zisanu zakutali" ntchito.

Ntchito zazikulu zachitetezo:
1) Chitetezo chozungulira chachifupi
2) Chitetezo chambiri
3) Zero sequence overcurrent chitetezo
4) Zero sequence overvoltage chitetezo
5) Chitetezo champhamvu kwambiri komanso chopanda mphamvu
Ilinso ndi ntchito monga kukumbukira zolakwika, kufufuza zolakwika, ndikudzifufuza nokha.
