Switchgear ndi mtundu wa zida zamagetsi, kunja kwa switchgear koyamba kumalowa mu switch yayikulu mu kabati, kenako ndikulowa mu switch yoyang'anira, ndipo gawo lililonse limayikidwa malinga ndi zosowa zake.
Zida, zida zodziwikiratu, makina oyendera maginito, mitundu yonse ya ma contactor a AC, ena amakhazikitsanso chipinda chocheperako komanso chipinda chamagetsi chotsika, ndi mabasi othamanga, monga magetsi, ena amakhazikitsidwanso kuteteza zida zazikulu zochepetsera kuchepa kwa sabata.
Ntchito yayikulu yosinthira nduna ndikutsegula ndi kutseka, kuwongolera ndi kuteteza zida zamagetsi popanga magetsi, kufalitsa, kugawa komanso kutembenuza mphamvu zamagetsi.
Zomwe zimayendetsedwa mu kabati yosinthira makamaka zimaphatikizapo dera loyimitsa, kulumikiza mosinthana, lophimba katundu, makina ogwiritsira ntchito, oyanjana mothandizana ndi zida zingapo zoteteza.
Pali njira zambiri zamagulu osinthira, monga makina oyimitsira dera amatha kugawidwa ndikusintha kosintha;
Kapena malingana ndi kapangidwe kosiyanasiyana ka nduna, itha kugawidwa pamakina otseguka, chitsulo chatsekedwa nduna, ndi chitsulo chotsekedwa ndi zida zanyumba;
Malinga ndi magulu osiyanasiyana amagetsi amatha kugawidwa m'magetsi othamanga, magetsi oyendera magetsi komanso magetsi otsika.
Makamaka ntchito zomera mphamvu, substations, petrochemical, zitsulo zitsulo anagubuduza, makampani kuwala nsalu, mafakitale ndi mabizinezi migodi ndi madera okhala, nyumba mkulu-nyamuka ndi zina zosiyanasiyana.
A. "Chitetezo Chisanu" cha High Voltage switchgear
1. Pambuyo pa trolley yamagetsi yamagetsi yamagetsi yamagetsi yamagetsi yamagetsi yothamanga kwambiri ikatseka pamalo oyeserera, trolley dera breaker silingalowe m'malo ogwirira ntchito. (Pewani kutseka ndi katundu)
2. Mpeni wokhazikitsira mu kabati yamagetsi yamagetsi yayikulu ili pamalo, chowombera galimoto sichitha kulowa ndikutseka.
3. Makina oyeserera otchinga mu kabati yamagetsi yamagetsi akugwira ntchito potseka, chitseko chakumbuyo kwa kabati chatsekedwa ndi makina pamakina oyikira pansi.
4. Chochotseka chazida chotsegulira pamagetsi chatsekedwa nthawi yayitali, ndipo mpeni wokhazikitsira sungayikidwe.
5. Chochotseka chazida chakuyenda kwamagetsi yamagetsi yayikulu sichitha kutuluka pamalo ogwirira ntchito oyendetsa galimoto akagwira ntchito. (Pewani kukoka ndi katundu)
B. Gawo
Ogawidwa ndi magetsi
Malinga ndi mtundu wama voliyumu, AC1000V ndi pansipa nthawi zambiri amatchedwa switchgear low-voltage (monga PGL, GGD, GCK, GBD, MNS, etc.), ndi AC1000V ndi pamwambapa amatchedwa switchgear high-voltage switchgear (monga GG- Nthawi zina mphamvu yamagetsi yamagetsi yamagetsi yamagetsi ndi AC10kV yotchedwa cabinet yamagetsi yamagetsi (monga XGN15 10kV ring network cabinet).
C. Wodziwika ndi mawonekedwe amagetsi
Kugawidwa mu: AC switch switch, DC switch switch.
D. Wodziwika ndi kapangidwe kamkati
Chotsani switchgear (monga GCS, GCK, MNS, etc.), switchgear (monga GGD, ndi zina zambiri)
E. Pogwiritsa ntchito
Olowera mzere nduna, akutuluka mzere nduna, muyeso nduna, chipani nduna (capacitor nduna), nduna ngodya, nduna basi.
Njira zogwirira ntchito
Njira Yotumizira Mphamvu
1. Ikani kaye kusindikiza kumbuyo koyamba, kenako ndikutseka chitseko chakutsogolo.
2. Gwiritsani ntchito chosinthana pansi ndikuchiyatsa.
3. Kankhirani galimoto yamanja (poyimilira) mu kabati (poyeserera) ndi galimoto yosamutsira (nsanja).
4. Ikani pulagi yachiwiri muzitsulo zosasunthika (chizindikiro cha malo oyesera chili), tsekani chitseko chapakati chakutsogolo.
5. kankhani kanyumba kandalama kuchokera pamalo oyeserera (lotseguka) kupita pamalo ogwirira ntchito ndi chogwirizira (chizindikiro cha malo ogwirira ntchito chikuyatsidwa, chizindikiro cha malo oyeserera chazima).
6. Kutseka galimoto yoyendetsa dera.
B. Mphamvu kulephera (kukonza) Njira
1 Tsegulani dera loyendetsa galimoto.
Tulukani galimoto m'manja kuchokera pamalo ogwirira ntchito (boma lotseguka lotseguka) kupita kumalo oyeserera ndi chogwirira.
3.
4 Tsegulani chitseko chapakati chakutsogolo.
5 Tulutsani pulagi yachiwiri pamtambo wokhazikika (chizindikiritso choyesa mayeso).
6. Tulukani galimoto yamanja (panja) kunja kwa kabati ndi galimoto yosamutsira.
7. Gwiritsani nthaka lophimba spindle ndi kupanga pafupi.
8. Tsegulani mbale yosindikiza kumbuyo ndi khomo lakumaso kwakumaso.
Kuwunika chitetezo ndi chitetezo
Kudzera mumayesedwe angapo azowunikira zamagetsi osiyanasiyana, mawonekedwe amkati mwamilandu arc amatsimikizika.
Pachifukwa ichi, chojambulira cha fiber chojambulira komanso chida chachuma komanso chothandiza chogawira zida zamkati zamkati zodziwira komanso chitetezo chimapangidwa pogwiritsa ntchito lamulo limodzi la arc.
Chipangizocho chili ndi maubwino osavuta, mtengo wotsika, nthawi yothamanga komanso kuthekera kwamphamvu kosagwirizana ndi zosokoneza.
Sikuti ingagwiritsidwe ntchito yokha, komanso itha kuphatikizidwa ndi zida zosiyanasiyana zotetezera, kuti mtengo wosinthira nduna usakwere, kuchuluka kwaukadaulo ndikuwonjezera phindu kumakulitsidwa bwino.
