Kufunika kosunga zosunga zobwezeretsera za chipangizo choteteza chitetezo

Malinga ndi ntchito mfundo yachipangizo chachitetezo cha surgendi makhalidwe a zigawo zikuluzikulu okha, mkati mphezi chitetezo Chip cha opaleshoni mtetezi adzakhudzidwa nthawi zambiri mphezi mphamvu panopa, ntchito overvoltage, kutentha ndi chinyezi mkulu pansi ntchito yachibadwa, kumayambitsa mphezi chitetezo Chip kukalamba, kuwonongeka.

Nthawi zambiri, kutayikira koyambirira kwa mtundu wochepera wapano (varistor)zida zodzitetezerandi zosakwana 40 ΜA, ndipo kutayikira koyambirira kwa oteteza mall surge ndi ochepera 5 ΜA, koma kutayikira kwapano kumayamba kuwonjezeka pang'onopang'ono pambuyo pa kutulutsa komweku komweku, ndikuwonjezeka kwa nthawi zotulutsa, kutulutsa kwaposachedwa kumawonjezeka mosalekeza.Pamene mphamvu yowonongeka ikuwonjezeka pamtengo wina (kawirikawiri, valavu imodzi sayenera kupitirira 1 Ma), chipangizo chotetezera kutentha chimayamba kutentha, ndipo kuwonongeka kwachangu kumakhala mofulumira, zomwe zimakhala zosavuta kuyambitsa moto.Komanso, pamene mkulu-mphamvu othamanga kapena mzere pafupipafupi chilema, opaleshoni mtetezi yochepa dera kulephera, ngati palibe chitetezo mzere, sangathe kusagwirizana chilema mzere mu nthawi, zidzachititsanso kugawa mzere moto, ndi opaleshoni mtetezi akuphulika.

Kuti tichite mwachidule, kutsekereza kutayikira kwa chipangizo chamkati cha chipangizo chachitetezo chamzere komanso kufupikitsa kwanthawi yayitali kwa ma frequency a Line Power ndiye zifukwa zazikulu zokhazikitsira chitetezo cham'mbuyo cha Surge Protector.

1 chitetezo chamkati cha chipangizo choteteza chitetezo

The kutayikira panopa pa opaleshoni mtetezi ndiye chinsinsi cha chitetezo chamkati chachipangizo chachitetezo cha surge.

Zina mwazogulitsa zamsika zoyamba kutayikira panopa ndizochepa kwambiri, koma padzakhala kuwonjezeka kwakukulu mutatha kugwiritsa ntchito, kusintha kwasintha kumakhala kwakukulu kwambiri.Mosiyana ndi izi, kutayikira kwa zida zina zoteteza maopaleshoni ndikokulirapo (5 ~ 30μa) , koma kuwonjezeka kwa kutayikira kwaposachedwa kumakhala kochepa kwambiri pambuyo poyesedwa mobwerezabwereza, yomwe ndi ndondomeko yofunikira kwambiri.Kukwera kwa kusintha kwa kutayikira kwapano, kumachepetsa chitetezo, kudalirika ndi moyo wautumiki wa chipangizo choteteza maopaleshoni.Kutsika kwa kusintha kwa kutayikira kwapano, kumapangitsa kuti chitetezo, kudalirika ndi moyo wautumiki wa chipangizo choteteza chitetezo chikhale chokwera.Pamene kutayikira kwapano mkati mwa oteteza opareshoni kumawonjezeka, kutentha kwamkati kwa chitetezo cha opaleshoni kumakwera mpaka malire, ndipo chipangizo chamkati chimatulutsidwa kudzera muzitsulo zotsika kutentha kapena ma shrapnel zitsulo zamakina, kuchotsedwa kwamphamvu kumagetsi kuonetsetsa chitetezo chachitetezo cha opaleshoni.Choncho, sitiyenera kuyang'ana yaing'ono kutayikira panopa, koma ayenera kulabadira kwambiri mlingo kusintha kutayikira panopa pa ntchito opaleshoni chitetezo chipangizo, zambiri ayenera kukhala zosakwana 200%.

2 chitetezo chakunja cha chipangizo choteteza chitetezo

Pakakhala kuchulukira kwamphamvu kwamphamvu kapena vuto lamagetsi pafupipafupi (Tov), malo otsetsereka sangatsimikizidwe kuti ndi malo osungunuka kwambiri chifukwa cha kupezeka kwa madzi otuluka kapena kupanikizika kwakukulu komwe kumachitika chifukwa chakukula kwa gasi, Surge Protector ndi yayifupi pansi, ndipo pompopompo yopitilira pang'onopang'ono imapangitsa kuti chitetezo cha opaleshoni chitenthe ndikugwira moto.Chifukwa chake, zida zodzitchinjiriza zikayikidwa chisanachitike chida choteteza chitetezo, zida zodzitchinjiriza kumbuyo zimadula ndipo mzerewo umatetezedwa pamene kulephera kwapang'onopang'ono kwa woteteza opaleshoni kumachitika.

(1) kulolerana ndi kukwera kwa mphamvu

Pamene Surge Protector ikugwira ntchito, kukwera kwamakono sikungoyenda kupyolera muchitetezo cha opaleshoni, komanso kumadutsa pazida zina zonse pamzerewu, kuphatikizapo zida zotetezera za Surge Protector.Pofuna kupewa zida zodzitetezera kuti zisagwiritsidwe ntchito molakwika pomwe mawotchiwa atha, chitetezo champhezi cha zida zodzitetezera chiyenera kusankhidwa moyenera.Papepalali, fusesiyo imatengedwa ngati chitsanzo kuti iwunikenso (zotsatira zikuwonetsa kuti mawonekedwe omwewo omwe amavotera oyendetsa dera ndi abwino kuposa momwe fuseji imayimilira) .

(2) chitetezo chachidule cha mphamvu pafupipafupi pa-panopa

Pamene kulolerana kwanthawi yayitali kapena kuphwanya kwapang'onopang'ono kwachitetezo chodzitchinjiriza palokha kumakhala kokulirapo kuposa momwe akuyembekezeredwa pazida zazifupi, woteteza opangira opaleshoni amawonedwa kuti ali ndi ntchito yoteteza, ndipo wotetezera wakunja sangathe kukhazikitsidwa. pakadali pano;Koma woteteza wamba wamba nthawi zambiri sangathe kukwaniritsa dongosolo lomwe likuyembekezeka kukhala lalifupi.Chifukwa chake, kulephera kwanthawi yayitali kwa chitetezo chachitetezo sikungathe kuthyolako pang'onopang'ono kwanthawi yayitali, woteteza opaleshoniyo ayenera kuyika chitetezo cham'mbuyo ndikutha kuthyolako komwe kumayembekezeredwa kwanthawi yayitali.

(3) kulumikizana kwachitetezo ndi switch yapamwamba

Chitetezo cham'mbuyo chiyenera kusankhidwa ndi kuchedwa kwa nthawi kumasulidwa ndi C kumasulidwa curve, ndipo mawonekedwe ake omwe amavotera amasankhidwa malinga ndi kuchuluka kwaposachedwa kwa chitetezo cha opaleshoni IMAX.Kapena sankhani fuyusi, iyenera kukhala fuyusi ndi mapeto apamwamba a mgwirizano wosankha (chiŵerengero cha mgwirizano wa 1/1.6) .Pamene mtengo wamtengo wapatali wa chitetezo chapamwamba cha overcurrent ndi wocheperapo kusiyana ndi mtengo wachitetezo cha overcurrent mu dera lotsogolera la Surge Protector, chitetezo chosungirako chitetezo cha opaleshoni sichigwira ntchito, ndipo mtengo wotsika mtengo ukhoza kuchotsedwa kapena kusankhidwa.

3 Kufananiza mitundu yosiyanasiyana ya zida zodzitetezera

Opanga oteteza msika wamakono amasankha mitundu yambiri ya zida zodzitetezera, zovuta.Mitundu yodziwika bwino ya zida zoteteza chitetezo chapadera (SCB), ma fuse ophatikizika (Fu), MCCB, micro-break (MCB) ndi zina zotero.Momwe mungasankhire mtundu ndi magawo akuluakulu a chitetezo cham'mbuyo sichinafotokozedwe momveka bwino komanso deta yolondola, ndipo ngakhale antchito osiyanasiyana aluso ali ndi malingaliro ambiri osagwirizana ndi mabodza, kwa okonza chisokonezo chochuluka.
