Zipangizo Zoteteza za AC Surge

Kukula kwa Ntchito

SPD ndi yoyenera mitundu yonse ya makina ogawa magetsi otsika omwe ali ndi magetsi otsika pansi pa 1000 volts komanso pafupipafupi ya 50/60HZ, monga positi ndi ma telecommunication, njanji, machitidwe azachuma, minda yamafuta, nyumba zazitali, nyumba ndi maofesi. Kuteteza zida zamagetsi (monga makompyuta, zida ndi zida, zida zapakhomo, ndi zina zotero) za ogwiritsa ntchito magetsi awa ku mphezi, magetsi opitilira muyeso komanso kuwonongeka kwina kwa magetsi opitilira muyeso. Onetsetsani kuti zida ndi chitetezo cha munthu payekha ndi chipangizo chabwino kwambiri choteteza magetsi opitilira muyeso.

Kapangidwe kake ndi mfundo yogwirira ntchito

Mu dongosolo la mawaya anayi la magawo atatu, zotetezera zimalumikizidwa pakati pa mawaya atatu ndi waya wopanda mbali ku waya wapansi (onani chithunzi pansipa). Muzochitika zachizolowezi, chotetezera chimakhala mu boma la Levin, ndipo pamene gridi yamagetsi ikukhudzidwa ndi mphamvu yowonjezereka chifukwa cha mphezi kapena zifukwa zina. Chotetezeracho chidzayatsidwa mwachangu munthawi ya nanosecond, ndikuyambitsa mphamvu yowonjezereka padziko lapansi, motero kuteteza zida zamagetsi zomwe zili pa gridi yamagetsi. Mphamvu yowonjezereka ikadutsa mu chotetezeracho ndikuzimiririka, chotetezeracho chimabwerera ku mphamvu yowonjezereka. Kuti chisakhudze ntchito yachizolowezi ya gridi yamagetsi.

Mbali

Mikhalidwe yachizolowezi yogwirira ntchito ya SPD

 

1. Kutalika sikupitirira 2000m:

2. Kutentha kwa mpweya wozungulira: mulingo wabwinobwino: -5℃+40℃, mulingo wotalikirapo: -40℃+70℃;

3. Wachibale wa mpweyaphokosoanality:30% -90% kutentha kwa mkati;

4. Kupendekeka kwa mzere wowongoka sikuyenera kupitirira 5.

5.Kumene kulibe kugwedezeka koonekeratu komanso kugwedezeka kwa mphamvu.

6. Palibe ngozi yophulika pakati pa zinthu, ndipo palibe mpweya ndi fumbi (kuphatikizapo fumbi loyendetsa mpweya) lokwanira kuwononga zitsulo ndikuwononga zotetezera kutentha mu sing'anga.

Chitsanzo

Choteteza mphamvu yowonjezereka

Chithunzi cholumikizira mawaya

 

Kukhazikitsa ndi miyeso yakunja

 

Zoteteza ma surge izi zimayikidwa ndi muyezo wokhazikika wa top-hat installation guide gauge, ndipo mfundo zotsatirazi ziyenera kuganiziridwa pokhazikitsa.

1. Waya wolumikizira ndi waya wosinthasintha wa 2.5-16mm² woyenera kuthamanga kwa madzi; Waya wolimba ndi 2.5-25mm²

2, Fuse kapena chosinthira mpweya chiyenera kulumikizidwa motsatizana kumapeto kwa chotetezera.

3, Zimitsani magetsi panthawi yokhazikitsa.

 

Kukonza

1, Pambuyo poti choteteza chayikidwa momwe chikufunira, chimatha kuteteza gridi yamagetsi yokha popanda kusintha.

2. Chizindikiro chikakhala chobiriwira, zikutanthauza kuti chikugwira ntchito bwino; chizindikiro chikakhala chofiira, zikutanthauza kuti gawo lomwe likugwiritsidwa ntchito pano lalephera ndipo liyenera kusinthidwa pakapita nthawi.

3. Yang'anani gawoli miyezi isanu ndi umodzi iliyonse ndikulisintha pakapita nthawi mutalephera.

4. Nthawi zonse onani ngati chosinthira mpweya kapena fuse yolumikizidwa motsatizana pamzerewu ndi yachibadwa.

 

Chiwongola dzanja cha utumiki

1. Yapangidwa mu fakitale yoyambirira

2、Kuwonongeka kumeneku kumachitika chifukwa cha vuto la khalidwe la wopanga.

 

Chitsimikizo sichikuphatikizapo zinthu zotsatirazi

1, kuwonongeka kopangidwa ndi anthu

2、Kuwonongeka komwe kumachitika chifukwa cha masoka achilengedwe monga kusefukira kwa madzi ndi mphamvu zazikulu;

3, Kuwonongeka komwe kumachitika chifukwa cha kulephera kukhazikitsa ndi kugwiritsa ntchito motsatira malangizo olondola mu kufotokozera kwa malonda.

4. Kuwonongeka komwe kumachitika chifukwa cha kugwiritsa ntchito zinthu zomwe zapitirira zomwe zafotokozedwa muukadaulo
