Kodi Chojambulira Module n'chiyani? Kodi Chili ndi Ntchito Zotani Zoteteza?

 Gawo lochaja ndilo gawo lofunika kwambiri pa kasinthidwe ka magetsi. Ntchito zake zoteteza zimaonekera m'mbali monga chitetezo cha magetsi olowera/otsika, chitetezo cha magetsi otuluka/alamu yamagetsi otsika, kubweza kwafupipafupi, ndi zina zotero. Ntchito”.

1. Kodi gawo lochaja ndi chiyani?

1) Gawo lochaja limagwiritsa ntchito njira yochotsera kutentha yomwe imaphatikiza kudziziziritsa yokha ndi kuziziritsa mpweya, ndipo imadziziziritsa yokha pakakhala mphamvu yochepa, zomwe zikugwirizana ndi momwe makina amagetsi amagwirira ntchito.

2) Ndi gawo lofunika kwambiri la kasinthidwe ka magetsi, ndipo limagwiritsidwa ntchito kwambiri pamagetsi a substations kuyambira 35kV mpaka 330kV.
2. Ntchito yoteteza gawo loyipiritsa opanda zingwe

1) Chitetezo cha voteji yolowera/yotsika

Moduleyi ili ndi ntchito yoteteza mphamvu yamagetsi yolowera/yotsika. Pamene mphamvu yamagetsi yolowera ili yochepera 313±10Vac kapena yoposa 485±10Vac, moduleyi imatetezedwa, palibe mphamvu ya DC yotuluka, ndipo chizindikiro choteteza (chachikasu) chimayatsidwa. Mphamvu yamagetsi ikabwerera kufika pakati pa 335±10Vac～460±15Vac, moduleyi imayambanso kugwira ntchito yokha.

2) Chitetezo cha overvoltage/alamu ya undervoltage

Module ili ndi ntchito yoteteza mphamvu yotulutsa mphamvu zambiri komanso alamu yoletsa mphamvu yotulutsa mphamvu. Pamene mphamvu yotulutsa mphamvu ili yoposa 293±6Vdc, module imatetezedwa, palibe mphamvu yotulutsa ya DC, ndipo chizindikiro choteteza (chachikasu) chimayatsidwa. Module singabwezeretsedwe yokha, ndipo module iyenera kuzimitsidwa kenako n’kuyatsidwanso. Pamene mphamvu yotulutsa mphamvu ili yochepera 198±1Vdc, alamu ya module, pali mphamvu yotulutsa ya DC, ndipo chizindikiro choteteza (chachikasu) chimayatsidwa. Pambuyo poti mphamvu yotulutsa mphamvu yamagetsi yabwezeretsedwa, alamu yoletsa mphamvu yotulutsa mphamvu yamagetsi ya module imatha.

3. Kubweza kwafupikitsa kwa magetsi

Module ili ndi ntchito yobweza mafunde afupiafupi. Pamene mafunde afupiafupi a module afupiafupi, mphamvu yotulutsa siipitirira 40% ya mphamvu yovotera. Pambuyo poti mphamvu yafupiafupi yachotsedwa, moduleyo imabwezeretsa mphamvu yotulutsa yachibadwa yokha.

4. Chitetezo cha kutayika kwa gawo

Gawoli lili ndi ntchito yoteteza kutayika kwa gawo. Gawo lolowera likasowa, mphamvu ya gawoli imakhala yochepa, ndipo mphamvu yotuluka imatha kulowetsedwa theka. Voliyumu yotuluka ikakhala 260V, imatulutsa mphamvu yamagetsi ya 5A.

5. Chitetezo chotentha kwambiri

Pamene mpweya wolowera mu module watsekedwa kapena kutentha kwa mlengalenga kwakwera kwambiri ndipo kutentha mkati mwa module kwapitirira mtengo wokhazikitsidwa, module idzatetezedwa ku kutentha kwambiri, chizindikiro choteteza (chachikasu) pa gulu la module chidzakhala choyatsidwa, ndipo module sidzakhala ndi mphamvu yotulutsa magetsi. Pamene vuto losazolowereka lachotsedwa ndipo kutentha mkati mwa module kwabwerera mwakale, module idzabwerera yokha kuntchito yachibadwa.
6. Chitetezo chachikulu cha mbali yozungulira

Ngati zinthu sizikuyenda bwino, mphamvu yamagetsi imapitirira muyeso kumbali ya chosinthira magetsi cha module, ndipo moduleyo imatetezedwa. Moduleyo singathe kubwereranso yokha, ndipo moduleyo iyenera kuzimitsidwa kenako nkuyambiranso kuyatsidwa.
