Ntchito yoteteza chitetezo

Surge, (Surge Protection Device) ndi chida chofunikira kwambiri pakuteteza mphezi pazida zamagetsi.Ntchito yachitetezo chachitetezo ndikuchepetsa kuchulukitsitsa komwe kumalowa mu mzere wamagetsi ndi chingwe chotumizira chizindikiro mkati mwa voteji yomwe zida kapena dongosolo limatha kupirira, kapena kutulutsa mphezi yamphamvu pansi kuti iteteze zida zotetezedwa kapena dongosolo. kuti asawonongeke.kuonongeka ndi kukhudzidwa.

surge chitetezo mfundo

Mfundo yogwira ntchito ya chitetezo cha opaleshoni ndi motere: chitetezo cha opaleshoni nthawi zambiri chimayikidwa kumapeto kwa chipangizo chotetezedwa ndikukhazikika.Pansi pazikhalidwe zogwirira ntchito, woteteza opangira opaleshoni amapereka kutsekeka kwakukulu kwamagetsi wamba pafupipafupi, ndipo pafupifupi palibe chomwe chimadutsamo, chomwe ndi chofanana ndi dera lotseguka;pamene kuwonjezereka kwapang'onopang'ono kumachitika m'dongosolo, chitetezo cha opaleshoni chidzayankha kuwonjezereka kwafupipafupi kwafupipafupi.Mphamvu yamagetsi imakhala yocheperako, yofanana ndi kufupikitsa zida zotetezedwa.

1. Kusintha kwamtundu: Mfundo yake yogwirira ntchito ndi yakuti pamene palibe kuwonjezereka kwadzidzidzi, kumapereka mphamvu yochuluka, koma ikayankhidwa ndi mphezi nthawi yomweyo, kusokoneza kwake kumasintha mwadzidzidzi kukhala mtengo wotsika, kulola kuti mphezi zidutse.Zikagwiritsidwa ntchito ngati zida zotere, zidazo zimaphatikizapo: mipata yotulutsa, machubu otulutsa mpweya, thyristors, etc.

2. Mtundu wochepetsera mphamvu yamagetsi: Mfundo yake yogwirira ntchito ndi yakuti imakhala yopingasa kwambiri pamene palibe kuwonjezereka kwadzidzidzi, koma kusokoneza kwake kudzapitirira kuchepa ndi kuwonjezeka kwa kuwonjezereka kwaposachedwa ndi magetsi, ndipo khalidwe lake lamakono lamagetsi ndilopanda malire.Zipangizo zomwe zimagwiritsidwa ntchito pazida zoterezi ndi: zinc oxide, varistor, suppressor diode, avalanche diode, etc.

3. Mtundu wa Shunt kapena mtundu wotsamwitsa

Mtundu wa Shunt: mofananira ndi zida zotetezedwa, umapereka kutsekeka kochepa kwa mphezi komanso kulepheretsa kwakukulu kumagwiritsidwe ntchito wamba.

Mtundu wa Choke: Motsatizana ndi zida zotetezedwa, umapereka kutsekeka kwakukulu kwa kugunda kwamphezi komanso kutsika kwapang'onopang'ono kumayendedwe wamba.

Zipangizo zomwe zimagwiritsidwa ntchito ngati zida zotere ndi monga: zotsekera, zosefera zodutsa kwambiri, zosefera zotsika, 1/4 wavelength short-circuiters, ndi zina zotero.
