Iyo varistor inoita basa rakakosha mudunhu.Kana iyo overvoltage ikaitika pakati pematanho maviri evaristor, hunhu hwevaristor hunogona kushandiswa kusungirira voltage kune yakatemerwa voltage kukosha, kuitira kudzvanya vhezheni mudunhu, kudzivirira iyo inotevera dunhu.
Saka unoziva here kuti aya mazwi: nominal voltage, varistor voltage, residual voltage ratio, insulation resistance, current capacity, uye leakage current zvinoreva kune varistors?Kana iwe usingazivi, verenga chinyorwa ichi kuti udzidze.
1. Nominal voltage (V): Iyo inozivikanwawo seyakatemerwa voltage, inoreva kukosha kwevoltage pane varistor kana DC ikozvino ye1m yapfuura.
2. Varistor voltage: The voltage value inoyerwa kumativi ose maviri evaristor apo chaiyo ikozvino (1mA DC) inoyerera kuburikidza nevaristor.
3. Residual voltage ratio: Kana iyo ikozvino kuburikidza nevaristor iri imwe kukosha, iyo voltage inogadzirwa kumativi ose maviri evaristor inonzi residual voltage yeiyi kukosha ikozvino.Residual voltage reshiyo ndiyo reshiyo yevoltage yasara kune inomina voltage.
4. Insulation resistance: iyo DC kushorwa kweiyo insulator pasi pemamiriro akatsanangurwa.Kudzivirira kwekudzivirira kwevaristor kunoreva kukosha kwekupokana pakati pewaya inotungamira (pini) yevaristor uye nzvimbo inodzivirira yeanopikisa.
5. Kuyerera kwehuwandu (kA): iyo yepamusoro yezvino kukosha inobvumirwa kudarika varistor pasi penguva yakatarwa yenguva uye nhamba yenguva, pasi pekushandiswa kwehuwandu hwemazuva ano.
6. Leakage current (mA): inoreva ikozvino inoyerera kuburikidza nevaristor pasi pekushisa kwakataurwa uye peak DC voltage.
Kunzwisisa iwo akakosha mazwi evaristors kunogona kubatsira kana zvasvika pakusarudza varistors.Sarudza mugadziri akavimbika kana uchitenga ceramic capacitors inogona kudzivirira yakawanda isina basa dambudziko.JYH HSU (kana kuti Dongguan Zhixu Electronics)kwete chete ine yakazara mamodheru eceramic capacitors ane yakavimbiswa mhando, asi zvakare inopa kunetseka-isina-kumashure-kutengesa.Kugamuchirwa kuti utitane nesu kana iwe uchida zvigadzirwa zvemagetsi.
