Kurongwa kwezvinodzivirira mheni zvakajairika.

Kune mhando dzakawanda dzezvinodzivirira mheni, kusanganisira zvinobata simbi oxide, zvinobata simbi oxide yemutsara, zvinobata simbi oxide yemutsara isina mipata, zvinobata simbi oxide yejaketi ine insulation yakakwana, uye zvinobata zvinobviswa.

Mhando huru dzezvibatiso ndedzinoti tubular arresters, valve arresters uyezvinodzivirira zinc oxide. Nheyo huru yekushanda kwemhando yega yega yekudzivirira mheni yakasiyana, asi hunhu hwavo hwekushanda hwakafanana, zvese izvi zvinodzivirira tambo yekutaurirana nemidziyo yekutaurirana kubva mukukuvadzwa.

Chinovhara chubhu
Chinovhara tubular mugero wekudzivirira une kugona kukuru kwekudzima arc. Chine migero miviri yakatevedzana. Imwe migero iri mumhepo, inonzi outer gap. Basa rayo nderekuparadzanisa voltage yekushanda uye kudzivirira pombi yekugadzira gasi kuti isafambe nepaipi. Yechipiri inopiswa ne power frequency leakage current; imwe yakaiswa mupombi yemhepo uye inonzi internal gap kana arc extinguishing gap. Kugona kwekudzima arc kwe tubular mugero wekudzivirira mafrequency kwakabatana nehukuru hwe power frequency continuous current. Iyi i protective gap lightning arrester, iyo inonyanya kushandiswa kudzivirira mheni pamitsetse yemagetsi.

Chibatiso chemhando yevharuvhu
Rudzi rwevharuvhumusungwaInoumbwa ne "spark gap" uye "valve plate resistor". Chinhu che "valve plate resistor" i "silicon carbide" chaiyo. "Valve chip resistor" yakagadzirwa ne "silicon carbide" inogona kudzivirira mheni uye voltage yakakwira, uye inodzivirira michina. Kana paine voltage yakakwira yemheni, "spark gap" inoputswa, kukosha kwe "resistance" ye "valve plate resistance" kunodzikira, uye "lightning current" inopinzwa muvhu, izvo zvinodzivirira tambo kana michina yemagetsi kubva mukukuvadzwa ne "lightning current". Mumamiriro ezvinhu akajairwa, "spark gap" haizoputswe, uye kukosha kwe "resistance" ye "valve plate resistance" kwakakwira, izvo zvisingakanganisi kutaurirana kwakajairika kwe "communication line".

Chinodzivirira zinc oxide
Chinodzivirira mheni chezinc oxidemudziyo wekudzivirira mheni une simba rekudzivirira rakanyanya, huremu hwakareruka, kuramba kusvibiswa uye kushanda kwakasimba. Unonyanya kushandisa hunhu hwakanaka hwe volt-ampere husina kurongeka hwe zinc oxide kuita kuti magetsi ari kuyerera nepakati pe arrester ave madiki (microamp kana milliampere level) pamagetsi anoshanda zvakanaka; kana overvoltage ikashanda, resistance inodonha zvakanyanya, ichiburitsa overvoltage Energy kuti iwane simba rekudzivirira. Musiyano uripo pakati pemhando iyi ye arrester ne traditional arrester ndewekuti haina discharge gap uye inoshandisa non-linear hunhu hwe zinc oxide kubuditsa nekupwanya.

Zvinoverengekazvinodzivirira mhenizvataurwa pamusoro apa. Rudzi rwega rwega rwechibatiso chine zvarunobatsira uye hunhu hwarwo. Chinofanira kushandiswa munzvimbo dzakasiyana kuti chiwane mhedzisiro yakanaka yekudzivirira mheni.
