Nenani za zina mwazida zoteteza ma SPD

Nenani za zina mwazida zoteteza (SPDs)

1. Mavuto ena amtundu wa "OBO kalembedwe"

Zida zaku China zodzitchinjiriza (SPDs) zopanga misa kutengera kapangidwe ka Dehn, OBO, ndi kapangidwe ka Citel. Komabe, pakukula kwa ukadaulo ndikuchita, kuchuluka kwa zinthu zokhwima kumasintha nthawi zonse, monga Dehn, Phoenix, Raycap, OBO, Citel, Hakel, Saltek surge protector, nthawi zonse amangobwera ndi mitundu yatsopano ndi mitundu. Zosinthazi sizimangokhala kusintha kwapamwamba, kusiyanitsa, koma pali mawonekedwe ndi magwiridwe antchito a kukhathamiritsa. Koma onani mafakitale ambiri a China SPDs, amagwiritsabe ntchito kapangidwe kakale monga kalembedwe ka OBO:

1.1 Kulumikizana kwakanthawi kochepa

1.2 Kukhazikitsa mzere

Pali vuto pakapangidwe ka OBO, makina opunthira, ndi MOV mchipinda chomwecho, zimatanthawuza olumikizana ndi ma voliyumu ndi ma voliyumu ocheperako mchipinda chomwecho.

(mkuwa woluka mkuwa; kusungunuka kwa solder)

Malinga ndi mfundo yamagetsi yamagetsi, Njira yomweyo imakokerana wina ndi mnzake, monga tawonetsera pamwambapa, pamene mkuwa woluka motalikirapo, imakoka pakati pa wochititsa mbali yomweyo ndi wochititsa mbali ina, chifukwa kuluka kwa mkuwa kumalumikiza ndikukhala ndi kuthekera Kutambasula, kumabweretsa zotsatira zakumwambaku

1.3 Kuwotcherera sikulimba pakati pa ulusi wamkuwa ndi mzere wamkuwa

Kapangidwe ka kalembedwe ka OBO, pali malo ochulukirapo pantchito iyi, ndikosavuta kukoka mzere pambuyo pakutha kwazomwe zikuchitika, kuwotcherera ndikosavuta kudumphira.

1.4 Chipinda cha pulasitiki chobiriwira chimakhala chosavuta kuwononga

Mfundo yofunika kwambiri pakapulasitiki wobiriwira ndikutsika kosavuta, mawonekedwe ofiira pazenera lowoneka, zimapangitsa kusagwirizana (zoyipa). Zimayambitsa chifukwa chofanana ndi chomwe chili pamwambapa 3.

1.5 Mtunda wotulutsidwa ndi wopapatiza kwambiri

Solder malata pang'ono, chitetezo chotentha kwambiri sichimatha kumasula kwathunthu. Mtunda wotulutsira ndi wochepera 5mm mu kapangidwe kamtundu wa OBO, opanga SPD ayenera kumvera.

Kuphatikiza apo, fanizirani kutulutsidwa kwachikale kwa DEHN

MOV ndi dongosolo lotulutsira mu chipinda china, mtunda wamasulidwewo ndi pafupifupi. 10mm, bala la pulasitiki silikukhudzidwa ndi mphamvu yamagetsi yamagetsi.

Onetsani mawonekedwe omasulira a DEHN

Chithunzithunzi chaposachedwa cha Raycap

Onetsani mawonekedwe omasulira a Phoenix

Onetsani mawonekedwe omasulira a OBO

Nkhani yosanyalanyazidwa ya IP20 yoteteza chitetezo

Kwa zaka zambiri, kuyesa kwa ma SPD kumayang'anira zotsalira zamagetsi, zotulutsa zakanthawi, zotumphukira kwakanthawi (TOV), kukhazikika kwamatenthedwe, ma pulse angapo, koma osanyalanyaza mayeso oyeserera a zida zamagetsi zamagetsi zochepa.

Pasanathe theka, labotale yoyesera ya SPD imapeza kalasi yambiri ya IP20 yopanda ziyeneretso za IPXNUMX, vutoli limachitika kale mumayendedwe akale a OBO, kuyitanitsa mafakitale aku China SPD sakutulutsanso, pali zovuta zambiri komanso mawonekedwe amtundu wakale wa OBO kalembedwe ka SPD .

Kodi njira za IP20 ndi ziti?

Nambala '2' amatanthauza kuteteza 12mm olimba (monga kukula kwa Zala), osagwiritsa ntchito zala zoyeserera kutsimikizira.
Nambala '0' amatanthauza mulingo wopanda madzi.

Musaganize kuti palibe vuto muzogulitsa zanu, kuwunika kowoneka bwino kumatha kukhala kuweruza.

Kujambula kumanzere: oyenerera, pamwamba pazowoneka ngati 1.5 mm

Kujambula kumanja: osayenerera

Mukamangitsa ndikumasula, mawonekedwe apamwamba a kagwereyo sayenera kusintha.

Udindo womangika
Pambuyo pofufuza, pansi pa nyumba ya SPD popanda kusiyana kulikonse, pezani zomata zosayenerera za IP20 sizoyeneranso nthawi yoyika nyumba zoyenera.

Monga kujambula pamwambapa, kujambula kumanzere: osakhudzidwa, oyenera oyenerera, kujambula kumanja: kukhudza, kuwombera osayenerera

Pambuyo muyeso, mfundo za wononga ndi zogwirizana, Vutoli limachitika pakupanga kwazitsulo.

Pamwamba pa wononga ndi osagwirizana mukayika pamakonzedwe azitsulo.

ndipo anapeza kuti pali kusiyana kwa mawonekedwe.

kapena gwiritsani ntchito chivundikiro, osafufuza.
