Kodi Chitetezo Chokwera Chimaletsa Kuthamanga kwa Dera?

Kodi Woteteza Wokwera Pewani Kugubuduzika Chotsegula Dera?

Ndinkataya ma breaker onse a resetting m'mawa wonse mu panel yanga mpaka nditafunsa funso limodzi losavuta.

Ayi, choteteza ma surge sichingalepheretse breaker yanu kugwa. Ma breaker amagwa pamene magetsi akuyenda kwambiri; ma surge protectors amangotseka ma short voltage spikes. Ndimasunga zipangizo zonse ziwiri m'ma panel anga chifukwa zimathetsa mavuto awiri osiyana.

Pitirizani kuwerenga ndipo ndikukuwonetsani chifukwa chake zipangizo ziwirizi sizimasinthana komanso momwe mungasankhire yoyenera pa ntchito iliyonse.

Kumvetsetsa Udindo wa Oteteza Odwala Odwala Machitidwe Amagetsi?

Ndinasinthana ma breaker atatu ndisanadziwe kuti sanali vuto—woteteza ma surge wanga anali kubisa vuto lenileni.

Choteteza mafunde sichimayendetsa magetsi; chimayamwa kapena kuchepetsa ma spikes amphamvu omwe amatha nthawi yochepa. Chimakhala moyandikana ndi katundu ndipo sichimasokoneza kayendedwe ka magetsi monga momwe chimachitira chopasula magetsi.

Zimene chitetezo cha surge chimachita kwenikweni

Chipangizo choteteza ma surge (SPD) chimamangirira ma voltage a line-to-line kapena line-to-ground omwe amakwera pamwamba pa mulingo wokhazikika, nthawi zambiri kuchulukitsa 1.5-2 kuposa nominal voltage. Chimachita izi ndi metal-oxide varistors (MOVs) kapena ma gas discharge tubes. Nthawi yochitira ndi nanoseconds, koma mphamvu yake ndi ma joules mazana ochepa okha a small plug-in strips ndi mpaka 100 kA ya panel-mount units. Mfundo yofunika kwambiri: sichimatsegula dera. Mphamvu imapitirira kuyenda; spike yokha ndiyo imasinthidwa.

Kumene timaziyika mu dongosolo

Chifukwa chake izi ndizofunikira kwa oyang'anira kugula zinthu

Ngati mugula ma breaker okha ndikusiya ma SPD, makina anu amagwirabe ntchito, koma kukwera kulikonse kumafupikitsa moyo wawo. Ngati mugula ma SPD okha ndikudumpha ma breaker, mumakhala pachiwopsezo cha moto pakagwa short circuit. Ndimasunga zonse ziwiri ku fakitale yanga ya Wenzhou chifukwa makasitomala ambiri a EU tsopano amapempha kuti EN 61643-4-11 itsatidwe pa lamulo lofanana ndi ma breaker specs.

Kodi N’chiyani Chimachititsa Kuti Opaleshoni ya Circuit Breakers Agwe — Ndipo N’chiyani Chimachititsa Kuti Agwe?

Ndinaonera galimoto ya 32 A breaker ikutsegulidwa Lachisanu masana ndipo tinalipira ndalama zonse chifukwa wina anawonjezera chotenthetsera chimodzi.

Chotsekereza chimagunda pamene mphamvu yamagetsi yapitirira mphamvu yake ya maginito kapena kutentha. Kukwera kwa magetsi, ma harmonics, kapena mafunde ang'onoang'ono otuluka sakugunda; mphamvu yamagetsi yeniyeni yokha ndi yomwe imagunda.

Ma curve awiri akuluakulu a ulendo

Zifukwa zenizeni zomwe ndimaona m'munda

1. Kudzaza zinthu mopitirira muyeso: Mumalumikiza ma heater awiri a 1500 W mu circuit imodzi ya 16 A. Mphamvu yamagetsi ndi 13 A pa heater iliyonse, kotero 26 A yonse pa breaker ya 16 A. Gawo la kutentha limatentha ndikutsegula patatha mphindi zochepa.
2. Dera lalifupi: Waya wosasunthika umakhudza bokosi la panelo. Impedance imatsika kufika pa zero, mphamvu yamagetsi imafika pa 1000 A, ndipo gawo la maginito limasuntha mu ma milliseconds.
3. Cholakwika cha nthaka: Chimodzimodzi ndi chachifupi, koma njira yake ndi kudzera mu waya wapansi. Ngati chopalira chanu chili ndi GFCI yomangidwa mkati, chidzatsegulidwa pa 30 mA kusalingana.

CHIMENE SICHIKUKHUDZANI CHOPHUNZITSA

- Kuthamanga kwa 300 V kwa 50 µs: Chosweka sichimawona ngati mphamvu yowonjezera.

- Choteteza ma surge: MOV imakoka ma amp angapo a microseconds; sikokwanira kutentha mzere wa bi-metal.

- Phokoso la ma radio-frequency: Iyi ndi voltage, osati current.

Ndinataya sabata yonse ndikutsatira "maulendo ovutitsa" mpaka nditagawa ma printer a laser omwe amalowa mwachangu pa C-curve breaker. Vuto latha, palibe zida zogwirira ntchito zomwe zimafunika.

Kodi Zoteteza Kuthamanga Ndi Zofunika Liti Mu Dongosolo Lanu Logawa Mphamvu?

Ndinataya ndalama zokwana $3000 PLC chifukwa cha mvula yamkuntho ndipo pamapeto pake ndinawonjezera ma SPD pa gulu lililonse—sipanakhalenso kusinthana kwa ma board kuyambira pamenepo.

Mumafunikira zotetezera mafunde pamene malo anu ali ndi mawaya atali, zamagetsi zomwe zimakhudzidwa, kapena mphezi. Sizimasiya kugwedezeka, koma zimaletsa kuwonongeka komwe kumachitika chitseko chisanachitepo kanthu.

Zinthu zitatu zoopsa zomwe zili mu tebulo

Masamu a mtengo ndi phindu omwe ndimapereka kwa ogula

Mtundu wachiwiri wa SPD wokhala ndi 40 kA umawononga fakitale yanga ya $12 FOB Wenzhou. Ndimaugulitsa kwa ogulitsa ambiri a EU pa $18. VFD imodzi yosungidwa imalipira mayunitsi 400. Jeff Weaver, wogula wanga wamba ku US, anandiuza kuti TCO yake yatsika ndi 8% atawonjezera ma SPD pamwamba pa gulu lililonse la magalimoto. Amakankhirabe magalimoto a magalimoto a magalimoto akadzaza macheka, koma sasinthanso magalimoto a magalimoto kotala lililonse.

Malangizo okhazikitsa omwe mungagawane ndi katswiri wamagetsi

- Ikani chopalira cha SPD pafupi ndi chopalira chachikulu kuti musunge zingwe zosakwana 50 cm.

- Gwiritsani ntchito waya wa 10 mm² kapena kuposerapo; inductance ndiye mdani.

- Onjezani chopumira cha 20 A C-curve cha SPD chokha; izi zimaletsa maulendo ovutitsa pamene SPD yafika kumapeto kwa moyo wake ndipo yatsala pang'ono kutuluka.

Kusankha Choteteza Choyenera cha Surge pa Ntchito Yanu?

Ndinayesapo mphamvu ya SPD yolakwika ndipo ndinapeza 277 V pa makina a 220 V; ma MOV anasuta mumphindi zochepa.

Sankhani SPD yokhala ndi voltage rating yomwe ikugwirizana ndi mtengo wanu wa line-to-ground, current rating yokwera kuposa momwe mukuyembekezerera, komanso njira yolephera yomwe imatseguka m'malo mwa shorts.
