Function
Iyo inosunga inobatanidzwa pakati petambo uye pasi, kazhinji inopindirana nemidziyo yakadzivirirwa.Musungwa anogona kudzivirira zvinobudirira midziyo yekutaurirana.Pane imwe nguva magetsi asina kujairika aitika, anosunga achaita uye achaita basa rekudzivirira.Kana tambo yekukurukurirana kana midziyo iri kushanda pasi penguva dzose yekushanda voltage, musungwa haashande, uye inoonekwa sedunhu rakavhurika pasi.Kana magetsi akakwira uye kuvharwa kwemidziyo yakadzivirirwa kwaiswa mungozi, anosunga achaita nekukasira kutungamira iyo yakakwira-voltage surge ikozvino kusvika pasi, nekudaro ichidzikamisa voltage amplitude uye kudzivirira kuvharirwa kwetambo dzekukurukurirana nemidziyo.Kana iyo overvoltage ichinyangarika, musungwa anokurumidza kudzoka kumamiriro ayo ekutanga, kuitira kuti mutsara wekutaurirana ushande zvakajairika.
Nokudaro, basa guru remusungwa nderokucheka kupindira kwekuyerera kwemafungu uye kuderedza kukosha kwepamusoro pemidziyo yakadzivirirwa kuburikidza nekushanda kweparallel discharge gap kana nonlinear resistor, nokudaro kudzivirira mutsara wekukurukurirana uye midziyo.
Mheni inosunga inogona kushandiswa kwete chete kudzivirira kubva kune yakakwira voltages inogadzirwa nemheni, asi zvakare kudzivirira kubva pakushanda yakakwira voltages.
