Kugawidwa kwa anthu wamba oletsa mphezi.

Pali mitundu yambiri yazotchingira mphezi, kuphatikizapo zomangira zitsulo, zomangira zitsulo zopanda mipata, zomangira zitsulo zopanda mafuta, zomangira zitsulo zopanda mafuta, ndi zomangira zochotseka.

Mitundu yayikulu ya zomangira ndi zomangira ma tube, zomangira ma valve ndizomangira zinki oxide.Mfundo yaikulu yogwirira ntchito ya mtundu uliwonse wa choletsa mphezi ndi yosiyana, koma mphamvu yawo yogwirira ntchito ndi yofanana, zonse zimateteza chingwe cholumikizirana ndi zida zolumikizirana kuti zisawonongeke.

Chomangira chubu
Chomangira chubu kwenikweni ndi mpata woteteza wokhala ndi mphamvu yayikulu yozimitsira arc. Chili ndi mipata iwiri yotsatizana. Mpata umodzi uli mumlengalenga, wotchedwa mpata wakunja. Ntchito yake ndikupatula mphamvu yogwirira ntchito ndikuletsa chitoliro chopangira mpweya kuti chisadutse mu chitoliro. Chachiwiri chimatenthedwa ndi mphamvu yotuluka ya ma frequency frequency; china chimayikidwa mu chitoliro cha mpweya ndipo chimatchedwa mpata wamkati kapena mpata wozimitsira arc. Mphamvu yozimitsira arc ya chomangira chubu imagwirizana ndi kukula kwa mphamvu yopitilira ya ma frequency current. Ichi ndi chomangira mphezi choteteza, chomwe chimagwiritsidwa ntchito kwambiri poteteza mphezi pamizere yamagetsi.

Chomangira mtundu wa valavu
Mtundu wa valavuwomangiraIli ndi mpata wa spark ndi resistor ya valavu. Zipangizo za resistor ya valavu ndi silicon carbide yapadera. Choletsa valavu chopangidwa ndi silicon carbide chimatha kuletsa mphezi ndi magetsi ambiri, ndikuteteza zidazo. Pakakhala magetsi amphamvu a mphezi, mpata wa spark umasweka, mphamvu ya kukana kwa valavu imatsika, ndipo mphamvu ya mphezi imalowetsedwa padziko lapansi, zomwe zimateteza chingwe kapena zida zamagetsi kuti zisavulale ndi magetsi a mphezi. Muzochitika zachizolowezi, mpata wa spark sudzasweka, ndipo mphamvu ya kukana kwa valavu ndi yokwera, zomwe sizingakhudze kulumikizana kwabwino kwa mzere wolumikizirana.

Choletsa zinki oxide
Choletsa mphezi cha zinc oxideNdi chipangizo choteteza mphezi chomwe chili ndi chitetezo chapamwamba, kulemera kopepuka, kukana kuipitsidwa kwa mpweya komanso magwiridwe antchito okhazikika. Chimagwiritsa ntchito makamaka makhalidwe abwino a volt-ampere a zinc oxide omwe si a linear kuti achepetse mphamvu yamagetsi yomwe imadutsa mu arrester (microamp kapena milliampere level) pa voteji yogwira ntchito bwino; pamene overvoltage ikugwira ntchito, resistance imatsika kwambiri, zomwe zimapangitsa kuti overvoltage Energy igwire ntchito bwino. Kusiyana pakati pa mtundu uwu wa arrester ndi arrester yachikhalidwe ndikuti ilibe mpata wotulutsa ndipo imagwiritsa ntchito makhalidwe osakhala a linear a zinc oxide kuti itulutse ndikusweka.

Zingapozotchingira mphezizafotokozedwa pamwambapa. Mtundu uliwonse wa chogwirira uli ndi ubwino ndi makhalidwe ake. Chimafunika kugwiritsidwa ntchito m'malo osiyanasiyana kuti chiteteze bwino mphezi.
