Kodi Surge Protector imagwira ntchito bwanji?

Ndikukumbukirabe phokoso la phokoso pamene mphezi inagunda denga la mnansi wathu. Lingaliro langa loyamba linali lakuti, “Chonde lolani MOV yomwe ili mkati mwa mzere wanga ivine.”

Choteteza ma surge chimatumiza magetsi owonjezera ku waya wapansi kudzera mu Metal-Oxide Varistor; popanda njira yotulukira imeneyo, mphamvuyo imakhalabe mu circuit yanu ndikuwotcha chip chofooka kwambiri.

Gawo laling'ono lomwe limatenga chipolopolo

Mkati mwa mzere uliwonse mupeza MOV imodzi kapena zingapo. Zimakhala pakati pa zamoyo ndi zapansi, zopanda mpweya ndi zapansi. Pa 130 V zimamangirira, koma chomangiracho chimagwira ntchito pokhapokha ngati nthaka ikudikirira ngati ngalande yotseguka.

Ma Joules amakuuzani kukula kwa chidebecho

Ndimasankha mizere yokhala ndi osachepera 600 J pa benchi yanga ya labu ndi 2,000 J pa raki za seva. Gome ili pansipa likuwonetsa kuchuluka kwa mafunde omwe MOV yachizolowezi ingameze isanasanduke briquette ya charcoal.

Chifukwa chiyani waya wobiriwira ndi wofunika kwambiri kuposa chizindikiro

Chingwe chingathe kunyamula UL 1449 koma chikulepheretseni. Ndatsegula mipiringidzo ya "CE-marked" yomwe inalibe ground pin pa pulagi. MOV idasokedwa ku pulasitiki yabodza. Kuthamanga kumapeza njira yabwino kwambiri - nthawi zambiri kudzera mu chingwe cha Ethernet ndikulowa mu bolodi la laputopu yanu.

Kodi chimachitika n'chiyani MOV ikafa?

Ma MOV sachira. Akagunda kwambiri, mphamvu yawo yolumikizira imakwera. Tsiku lina mphamvu imakwera kuposa MOV yotopa ndipo mphamvu imalowa mumagetsi anu. Ndimasintha ma strips zaka zitatu zilizonse ku mphezi, zaka zisanu zilizonse kwina.

Kodi Zoteteza Zonse za Surge Zili ndi Maziko?

Ndinaphunzira movutikira kuti chizindikiro cha "surge" pa bokosi sichikutanthauza kuti bala ili ndi ground pin; zina zimangoteteza mizere ya data ndikusiya njira yamagetsi ili maliseche.

Ayi, zoteteza zambiri zoyenda komanso zopinga ziwiri sizili ndi kulumikizana kwa pansi; zimadalira kukanikiza kwa mzere wopanda malire ndipo zimangopereka chitetezo chochepa.

Chinyengo cha malonda chomwe chinandinyenga

Chaka chatha ndinagula bala loyera lokongola kuti ndijambule zithunzi. Pulagiyo inali ndi mapini awiri okha. Mapepala olembedwa bwino anali ndi mawu akuti "chitetezo cha mafunde pakati pa mizere." Zimenezi zimathandiza kuti pasakhale kutukumuka pang'ono, koma mphezi ikakankhirabe 6 kV pa chassis.

Tebulo lolumikizira la mapini awiri

Chifukwa chake ndimagwiritsabe ntchito mipiringidzo iwiri

Ndimazigwiritsa ntchito, koma pa nyali ndi ma charger a foni okha. Ndimazilemba kuti “PASI PANSI—PASI ZIPANGIZO ZAMTENGO” kotero kuti ophunzira anga asamaike oscilloscope m'magalimoto awo.

Malo a imvi: Malo ogulitsira a GFCI

Ma lab ena akale ali ndi malo otulutsira GFCI opanda malo olowera pansi. GFCI idzakupulumutsani, koma imapangitsa kuti phokosolo lisapitirire. Ndimawonjezera gawo lina la MOV lomwe lili pamzere lomwe lili ndi waya ku payipi yamadzi ndikakumana ndi izi.

Zoopsa ndi Zoopsa Zokhudza Chitetezo Chogwiritsa Ntchito Surge Protectors Ungrounded

Ndinamva fungo la pulasitiki yoyaka nthawi ya 2 koloko m'mawa mu hotelo; mzerewo unalibe nthaka ndipo mphamvu ya galimotoyo inadutsa mu chingwe cha USB-C, ndikulumikiza laputopu yanga kupita nayo pa desiki.

Popanda nthaka, mphamvu yowonjezereka imatha kulowa mkati mwa mzerewo, kuyatsa pulasitiki, kapena kudutsa mu zingwe za netiweki ndikuwononga chipangizo chilichonse cholumikizidwa.

Moto umayamba mkati mwa pulasitiki

Ma MOV amatentha. Mzere wosasunthika umathira kutentha ndi ma elekitironi pamodzi. Mzere wosasungunuka umasunga mphamvu. Ndaona thovu la nkhope likutuluka ngati tchizi pa poto.

Njira yobisika kudzera mu Ethernet

Ndinayeza 1,800 V pakati pa ma laputopu awiri omwe anali ndi mzere wosazungulira. Kuthamanga kunadutsa pa chingwe cha CAT6 ndipo kunawononga ma NIC onse awiri. Ndalama zokonzera zinali zokwera kuposa chaka chimodzi cha ma surge bar.

Ngozi ya anthu yokhudza kugwedezeka kwa maganizo

Ngati mphamvu yamagetsi ya kompyuta yanu ilibe nthaka, chikwama chachitsulo cha kompyuta yanu chikhoza kukwera mpaka theka la mphamvu yamagetsi ya mzere kwa ma microseconds. Izi ndi nthawi yayitali yokwanira kukudabwitsani ngati mutakhudza chikwamacho ndi nthaka yeniyeni nthawi imodzi.
