MFUNDO YOFUNIKA YA SWITCH YA VOLTAGE LOAD SWITCH

Chosinthira champhamvu chamagetsi chimagwiritsa ntchito bwino ubwino wozimitsa moto wa chubu chosinthira cha vacuum ndi njira yogwirira ntchito yofanana. Popeza chosinthira champhamvu chamagetsi sichingathe kuswa mphamvu yamagetsi yafupikitsa, ndi chosavuta kupanga ndipo chimayenera kuchitika nthawi zina pomwe mphamvu yamagetsi yaying'ono komanso nthawi zambiri. Pali ma switch awiri odziwika bwino amagetsi amphamvu: mtundu wamkati ndi mtundu wa mizati yakunja.

Pali mitundu yambiri ya ma switch okhala ndi mphamvu zambiri, ndipo kapangidwe kake kakhoza kugawidwa m'ma switch okhala ndi mphamvu zambiri zamafuta, ma switch okhala ndi mphamvu zambiri za vacuum, ma switch okhala ndi mphamvu zambiri za sulfure hexafluoride, ma switch okhala ndi mphamvu zambiri za gasi komanso ma switch okhala ndi mphamvu zambiri za mpweya wopanikizika, ndi zina zotero; malinga ndi momwe ntchito ikuyendera, imagawidwa m'magawo ogwirira ntchito. Pali mitundu iwiri ya ma switch okhala ndi mphamvu zambiri zamagetsi ndi ma switch okhala ndi mphamvu zamagetsi. Zogulitsazi zimayikidwa mu netiweki yogawa, monga makabati a netiweki ya mphete. Pakadali pano, ma switch okhala ndi mphamvu zambiri za vacuum ndi otchuka kwambiri, ndipo ma switch okhala ndi mphamvu zambiri ali ndi ma fuse ndi zida zina. Chisamaliro chachikulu chaperekedwa pakupititsa patsogolo ntchito yosinthira netiweki. Zotsatirazi zikufotokoza makhalidwe a kapangidwe kake ndi mfundo zoyambira za ma switch awiri okhala ndi mphamvu zambiri zamagetsi.

Chosinthira chamagetsi champhamvu kwambiri chimayikidwa kwathunthu pa bulaketi yake yokhazikika. Njira yake yogwiritsira ntchito iyenera kugwira ntchito mwanjira yomwe yatchulidwa, makamaka, ngati njira yogwiritsira ntchito ndi yamagetsi kapena yopumira, ntchito yake iyenera kuchitika pamagetsi ochepa kapena mpweya wochepa, motsatana, pokhapokha ngati kusokonekera kwa mphamvu yamagetsi kungakhudze zotsatira za mayeso. Pankhaniyi, mphamvu yamagetsi kapena mpweya panthawi yogwiritsira ntchito chosinthira chamagetsi iyenera kusankhidwa mkati mwa malire omwe atchulidwa kuti ikhale ndi liwiro lapamwamba kwambiri komanso magwiridwe antchito apamwamba kwambiri ozimitsa arc pamene ma contacts alekanitsidwa. Iyenera kusonyezedwa kuti chodulira chosinthira chimagwira ntchito mokwanira pansi pa mikhalidwe yopanda katundu pansi pa mikhalidwe yomwe ili pamwambapa. Ngati n'kotheka, deta monga kuyenda kolumikizana kosuntha iyenera kulembedwa. Zosinthira zamagetsi zomwe sizigwiritsidwa ntchito ndi manja zimatha kuyendetsedwa pogwiritsa ntchito kutseka kwakutali.

1. Kusankha koyenera kwa cholumikizira cha mbali yamoyo kuyenera kuganiziridwa. Pamene chosinthira cholozera magetsi chikukonzedwa kuti chilumikizidwe ndi magetsi kuchokera mbali zonse ziwiri, ndipo kapangidwe kake ka mbali imodzi ya chosinthira magetsi ndikosiyana ndi kapangidwe ka mbali inayo, mphamvu yamagetsi ya dera loyesera iyenera kulumikizidwa kumbali yomwe ikuwonetsa momwe chosinthira cholozera magetsi chilili chovuta kwambiri. Ngati pali kukayika, gawo la ntchitoyo liyenera kuchitidwa ndi mphamvu yolumikizidwa mbali imodzi ya chosinthira magetsi, ndipo gawo lina la ntchitoyo liyenera kuchitidwa ndi mphamvu yolumikizidwa mbali inayo ya chosinthira magetsi.

2. Kuyesa kupanga ndi kuswa kwa switch yamphamvu yamagetsi atatu yomwe imagwiritsidwa ntchito nthawi imodzi ndi ndodo iliyonse kuyenera kuchitika pa magawo atatu pokhapokha ngati patchulidwa mwanjira ina.

Kuyesa kupanga ndi kuswa kwa switch ya pole-ndi-pole pogwiritsa ntchito pole-ndi-pole (yopangidwa ndi ma switch atatu a single-pole high-voltage load) kuyenera kuchitika ndi single-phase, kupatula mayeso a capacitive load breaking omwe ali ndi zofunikira zapadera.

3. Kupatula ma switch odzaza ndi madzi kapena gasi ndi ma switch odzaza ndi vacuum, ngati pali moto kapena tinthu tachitsulo tomwe timabalalika kwambiri, mungafunike kugwiritsa ntchito chophimba chachitsulo kuti chiyikidwe pafupi ndi zinthu zamoyo komanso kutali nazo panthawi yoyesa. Mtunda wotetezedwa womwe waperekedwa ndi fakitale. Ma screen achitsulo, mabulaketi ndi zinthu zina zomwe nthawi zambiri zimakhala pansi ziyenera kutetezedwa kuchokera pansi ndikulumikizidwa wina ndi mnzake kenako kulumikizidwa ku chipangizo choyenera chokhazikitsira pansi kuti chiwonetse ngati pali kutuluka kwamphamvu kwa mphamvu pansi.
