Gulu wamba logwirizira mphezi.

Pali mitundu ingapo ya omanga mphezi, kuphatikiza omanga achitsulo okusayidi, omata amizere achitsulo, omata opanda zingwe okhala ndi mzere wama oxide, omangidwa kwathunthu ndi jekete yazitsulo zomata, ndi omanga omwe amachotsedwa.

Mitundu yayikulu yakumangidwa ndi ma tubular arresters, ma valve akumangiriza ndi zinc oxide arresters. Mfundo zazikuluzikulu zogwirira ntchito zamtundu uliwonse wamtundu wa mphezi ndizosiyana, koma magwiridwe antchito ndi ofanana, onse amateteza chingwe cholumikizirana ndi zida zolumikizirana kuti zisawonongeke.

Tube arrester
Womanga tubular ndiye malo otetezera omwe amatha kuzimitsa arc. Ili ndi mipata iwiri. Kusiyana kumodzi kumakhala mumlengalenga, kotchedwa kusiyana kwakunja. Ntchito yake ndikupatula magwiridwe antchito ndikuletsa chitoliro chopangira mpweya kuti chisadutse chitoliro. Chachiwiri chimatenthedwa ndimphamvu yamagetsi yamafupipafupi; ina imayikidwa mu chitoliro cha mpweya ndipo imatchedwa kusiyana kwa mkati kapena arc yozimitsa. Kuzimitsa kwa arc kwa tubular arrester kumayenderana ndi kukula kwa mafupipafupi amagetsi opitilira muyeso wapano. Ichi ndi chotchinga chotsekera mphezi, chomwe chimagwiritsidwa ntchito poteteza mphezi pamagetsi amagetsi.

Vavu mtundu arrester
Womanga-valavu wamtunduwu amakhala ndi tinthu tating'onoting'ono tomwe timakanikira pamiyeso yamagetsi. Zomwe zimatsutsana ndi mbale ya valve ndiyapadera ya silicon carbide. Chophimba cha valve chip chopangidwa ndi silicon carbide chitha kuteteza bwino mphezi ndi ma voliyumu akulu, komanso kuteteza zida. Pakakhala mphamvu yamagetsi, mpata umathyoledwa, mtengo wamagetsi wamagetsi wamagetsi, ndipo mphezi imayambitsidwa padziko lapansi, yomwe imateteza chingwe kapena zida zamagetsi pakuwononga mphezi. Nthawi zonse, kusiyana kothetheka sikudzaphwanyidwa, ndipo mtengo wotsutsana wa kukanikiza kwa valavu ndiwokwera, komwe sikungakhudze kulumikizana kwabwinoko kwa kulumikizana.

Zinc oxide arrester
Nthaka oxide mphezi arrester ndi chipangizo chitetezo mphezi ndi ntchito kuposa chitetezo, kulemera, kukana kuipitsidwa ndi ntchito khola. Amagwiritsa ntchito bwino ma volt-ampere ampere ampere ampere wa oxide wa zinc kuti apange zomwe zikuyenda pakadali pano kuti zikhale zazing'ono kwambiri (microamp kapena milliampere level) pama voliyumu ogwira ntchito; kukokomeza kukachita, kulimbikira kumatsika mwamphamvu, kutulutsa mphamvu ya Mphamvu kuti iteteze. Kusiyanitsa kwamtundu wamtunduwu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtunduwu ndikuti alibe mpata wogwiritsira ntchito ndipo amagwiritsa ntchito mawonekedwe osakanikirana a zinc oxide kuti atuluke ndikuphwanya.

Ozimitsa mphezi angapo afotokozedwa pamwambapa. Mtundu uliwonse wamndende uli ndi zabwino zake komanso mawonekedwe ake. Iyenera kugwiritsidwa ntchito m'malo osiyanasiyana kuti ikwaniritse bwino mphezi.
