I-Zinc oxide arrester iwuhlobo olusha lwesibophisi olwakhiwa ngawo-1970, olwakhiwa ikakhulukazi i-zinc oxide varistor.I-varistor ngayinye ine-voltage yayo yokushintsha (ebizwa ngokuthi i-varistor voltage) lapho yenziwa.Ngaphansi kwe-voltage evamile yokusebenza (okungukuthi, ngaphansi kwe-varistor voltage), inani le-varistor likhulu kakhulu, elilingana nesimo sokushisa, kodwa ku-voltage evamile yokusebenza (okungukuthi, ngaphansi kwe-varistor voltage) Ngaphansi kwesenzo i-voltage impulse (inkulu kune-voltage ye-varistor), i-varistor iphukile ngenani eliphansi, elilingana nesimo esifushane sesifunda.Kodwa-ke, ngemva kokushaywa kwe-varistor, isimo se-insulating singabuyiselwa;lapho i-voltage ephakeme kune-varistor voltage ihoxiswa, ibuyela esimweni sokumelana okuphezulu.Ngakho-ke, uma i-zinc oxide arrester ifakwe entanjeni yamandla, lapho umbani ushaya, amandla aphezulu ombane wegagasi lombani abangela ukuphuka kwe-varistor, futhi umbani wamanje ugeleza emhlabathini ngokusebenzisa i-varistor, engakwazi ukulawula ukukhanya. i-voltage kulayini kagesi phakathi kwebanga eliphephile.Ngaleyo ndlela ukuvikela ukuphepha kwezinto zikagesi.
