(1) Basa reHigh-Voltage Line Arrester
High-voltage line arrester ye 6 ~ 220kV AC kutapurirana mitsetse, rudzi rutsva rwekusunga mheni yakamiswa uye yakaiswa pane transmission tower.
Transmission line arrester: kunyanya insulated zinc oxide arrester.
Distribution line arrester: valve type arrester, tube type arrester, zinc oxide arrester, etc.
Basa guru repamusoro-voltage line arrester ndiro
Limit high-voltage line mheni overvoltage.
Kuvandudza chiyero chepamusoro-voltage line mheni kuramba.
Deredza kugumburwa kunokonzerwa nekukanganisa kwemheni muhurongwa.
(2) Iyo Nheyo Yepamusoro-Voltage Line Arrester
A high-voltage line arrester ine mafomu maviri.
Imwe inowanzoiswa mukuenderana nemutsara insulator tambo, musungwa anogona kubatanidzwa munhevedzano kuti aite gap. Uye ita kuti iyo yekuputsa voltage yakaderera pane iyo insulator tambo flashover voltage.
Zvekuti iyo yakakwira-voltage mutsara inosunga mu insulator tambo isati yaparara flashover, kuiswa kwayo kunotevera.
Imwe igapless arrester yakananga musystem, kushandiswa kwekusungirira kuramba kusina mutsara uyu hunhu kuchengetedza tambo ye insulator. Ose ari maviri anogona kuvandudza mwero wekupokana kwemheni yematambo ekutapurirana, uye nokudaro kuderedza mwero wemheni inofamba, kuwedzera kuvimbika kwekushanda kwetambo yekufambisa.
High-voltage line arrester uye high-voltage line insulators zvakafanana. Kana mheni yarova sunga chiito, iyo yakasara voltage yemusungwa yakaderera pane 50% ye insulator tambo discharge voltage. Kunyange kana mheni ikawedzera, iyo yakasara voltage yemusungwa yakawedzera zvishoma, iyo insulator haisati yaitika flashover. Mushure mokuyerera kwemheni, iyo frequency kuenderera ikozvino ichiyerera kuburikidza nemusungwa inongova milliampere, iyo frequency yekuenderera ikozvino inoyerera kuburikidza nemusungwa inodzima panguva yekutanga pamusoro zero, haizogumburwi, iyo system inodzokera kune yakajairika.
Mufananidzo unotevera unoratidza high-voltage line arrester uye high-voltage line insulator volt-masekondi maitiro ehukama hwekubatana. Iyo volt-yechipiri maitiro emusungwa kupfuura insulator volt-yechipiri maitiro ezvinopfuura 15% pasi, apo kudzoka shure, inogona kuva yakaderera pane 20%.
