Kodi cholumikizira chingwe chili ndi makhalidwe otani?

(1) Chingwe cha switchgear cha 35kV SF6 chotsekedwa bwino chimayikidwa mu soketi yapadera yomwe ili m'chipinda chaching'ono chotsekedwa bwino cha switchgear, ndipo ziwalo zonse zowonekera zili pansi.

(2) Ma terminal a chingwe a 10kV SF6 otsekedwa bwino (kabati ya netiweki yozungulira) amagawidwa m'magawo olumikizira olekanitsidwa okhala ndi ngodya yakumanja (okhala ngati chigongono) (a 200A) ndi olumikizira olekanitsidwa okhala ndi ngodya yakumanja (omwe amagwiritsidwa ntchito kwambiri pa 630A). Palinso chivundikiro chapadera choteteza cha chingwe, ndiko kuti, chivundikiro chapadera choteteza chimagwiritsidwa ntchito kuphimba gawo lamoyo.

Cholumikizira chingwe chimakonzedwa kale mufakitale yokhala ndi zigawo zazikulu, ndipo chimapambana mayesowo mufakitale. Cholumikizira chingwe chimayikidwa mokwanira mu soketi yapadera yomwe ili mu chipinda chotsekedwa bwino cha kabati yosinthira, ndipo gawo lowonekera limakhazikika.

2. Kulumikizana pakati pa chingwe cholumikizira ndi kabati yosinthira

(1) Cholumikizira cha 35kV chimalumikizidwa ndi mapulagi oyenda komanso osasinthasintha, ndipo cholumikizira cha chingwe chimayikidwa mu soketi ya chingwe yokonzedweratu ya kabati yosinthira. Soketiyo imachotsedwa kwathunthu kuchokera mkati mwa kabati yosinthira, ndipo kuyika kwa zingwe sikukhudza momwe mkati mwa kabati yosinthira mulili. Chithunzi 4-12 ndi chithunzi cha kutha kwa chingwe cha 35kV cholumikizira.

(2) Zolumikizira zolumikizira zolekanitsidwa ndi ngodya yakumanja nthawi zambiri zimakhala zoyenera ma feeder a transformer. Kulumikizana kwa chingwe chamagetsi ndi kabati yosinthira kumakhala ndi zigawo zotsetsereka. Ikani mwachindunji mu chithandizo cha kabati yosinthira kudzera mu cholumikizira, ndikulumikiza ndi gawo lamagetsi la kabati yosinthira. Chithandizocho chimachotsedwa kwathunthu mkati mwa kabati yosinthira, ndipo kuyika zingwe sikukhudza momwe kabati yosinthira ilili mkati.

(3) Cholumikizira cholumikizira cha mtundu wa bolt yolumikizana ndi plug-in yolunjika kumanja chimalumikizidwa ndi mabotolo a M16 stud ku mabowo a screw omwe ali pa chithandizo cha kabati yosinthira. Chithandizocho chimachotsedwa kwathunthu kuchokera mkati mwa kabati yosinthira, ndipo kuyika zingwe sikukhudza momwe kabati yosinthira ilili mkati.

1) Chowonjezera cha kabati yosinthira magetsi ndikugwiritsa ntchito magetsi ku chowonjezera chapadera, ndikuchita mayeso a magetsi okhazikika pa chingwe kudzera mu chipangizo cholumikizira mkati mwa kabati yosinthira magetsi.

2) Zipangizo zolumikizira chingwe zimayesa mphamvu yamagetsi yokhazikika pa chingwe cholumikizira. Sizifunika kulekanitsa chingwe ndi kabati yosinthira, ndipo zitha kuchitika mwachindunji pa kabati yosinthira. Chifukwa chake, gawo lolumikizira la switch yolekanitsa mzere wa kabati yosinthira ndi chingwe limafunika kuti likhale ndi mphamvu yamagetsi yokhazikika yokhazikika ngati chingwe.

(2) Kuwunika ndi kuyesa njira zomangira magetsi pogwiritsa ntchito chingwe:

Chosinthira magetsi chotsekedwa bwino chili ndi njira zabwino kwambiri zotetezera chitetezo. Njira zotetezera magetsi chosinthira magetsi zakhala zokwanira, ndipo ntchito yake ndi kupewa kugwiritsa ntchito molakwika, zomwe zingalepheretse kumangidwa kwa chingwe pamene mpeni wothira pansi sunatsekedwe. Komabe, ndikofunikirabe kuwonjezera njira zotetezera pamalopo panthawi yomanga chingwecho. Malinga ndi zofunikira za DL 409-1991 "Malamulo Ogwira Ntchito Zachitetezo cha Makampani Amagetsi", pogwira ntchito pa waya woyimitsa, dera liyenera kuyesedwa, kutulutsidwa, ndi kukhazikika pansi. Komabe, ntchitozi sizingachitike pazingwe za chingwe zolumikiza chosinthira magetsi chotsekedwa bwino. Kuweruza ngati chingwe chili ndi magetsi kapena ayi kungadalire kokha pa kuweruza momwe chosinthira magetsi chikugwirira ntchito, komwe kumafuna chipangizo chowunikira chamagetsi.

Ndi kuphatikizana kwabwino kwa switchgear ndi ntchito ya chingwe, kuyang'anira magetsi ndi kukhazikitsa ntchito yokhazikitsa pansi kudzachitika kudzera mu switchgear.

1) Kuyang'ana magetsi kudzera mu kabati yosinthira: Chida chogwiritsira ntchito cha kabati yosinthira yotsekedwa bwino chili ndi zida zowunikira zamagetsi, zomwe zimapambana kuyang'ana magetsi kwachiwiri.

2) Kuyang'ana magetsi kudzera mu chipangizo chowunikira magetsi choperekedwa: Ngati chosinthira magetsi cha 35kV chotsekedwa bwino chokhala ndi ma plug-in terminals chikugwiritsidwa ntchito, wopanga angapereke chipangizo chowunikira magetsi choperekedwa kuti chiziyang'ana magetsi mwachindunji malo opanda chingwe. Komabe, pambuyo poti plug-in terminal yayikidwa, sizingatheke kuyesa magetsi mwachindunji pa gawo la terminal la chingwe. Ngati plug-in terminal ya 10kV ikugwiritsidwa ntchito, ikhoza kuyang'ana magetsi pamalo owunikira magetsi omwe asungidwa pa chingwe kudzera mu zida zapadera zomwe zaperekedwa ndi icho. Komabe, chidziwitso cha chipangizo chowunikira magetsi chamtunduwu sichikudziwika bwino, ndipo ntchito yeniyeniyo imadalira kudalirika kwa chipangizo chapaderacho.
