Malangizo a DC ndi AC SPD Type 2 a Dzuwa ndi Magetsi

Ndawonapo chochitika chimodzi cha kukwera kwa nthaka chikuchotsa ntchito ya miyezi yambiri, kotero nthawi zonse ndimachitira nkhanza Chipangizo Choteteza Kuwonjezeka monga chinthu chofunikira kwambiri pakupanga, osati chowonjezera chomwe mungasankhe.

Buku lotsogolera la DC ndi AC SPD Type 2 limafotokoza momwe Chipangizo Choteteza Kuwonjezeka Mayankho amateteza mphamvu za dzuwa ndi zamagetsi ku mphamvu yamagetsi yosakhalitsa, amawonjezera nthawi yogwira ntchito, komanso amachepetsa ndalama zosamalira ndi kusintha kwa nthawi yayitali.

Ngati mukufuna kudziwa zambiri zokhudza kutumiza zinthu modalirika, khalidwe lokhazikika, komanso mtengo wotsika wa umwini, kumvetsetsa kuti mtundu wachiwiri wa SPDs ndi malo anzeru kwambiri oyambira.

Kodi Chipangizo Choteteza Kuthamanga kwa DC N'chiyani?

Nthawi zambiri ndimaona zoopsa za DC zimanyalanyazidwa mpaka zida zitalephera kugwira ntchito, kotero nthawi zonse ndimayamba kuwunikanso makina kuchokera kumbali ya DC.

A Chipangizo choteteza DC surge Kumachepetsa mphamvu yamagetsi yosakhalitsa pa ma DC circuits mwa kusuntha mphamvu yamagetsi kupita pansi mosamala, kuteteza zida zolumikizidwa kuti zisawonongeke.

Ndimaona chitetezo cha DC surge ngati gawo loyamba lodzitetezera mu mphamvu za dzuwa ndi mafakitale. Ma circuit a DC amaonekera, amakhala ataliatali, ndipo nthawi zambiri amaikidwa panja. Zimenezi zimapangitsa kuti azikhala otetezeka kwambiri ku ma surges oyambitsidwa ndi mphezi komanso ma transient transients. Chipangizo Choteteza Kuwonjezeka Choyikidwa mbali ya DC chimagwira ntchito mkati mwa nanoseconds ndipo chimatseka ma voltage spikes oopsa asanafike pamagetsi ofunikira.

Mu malo enieni okhazikitsa, ma DC SPD amateteza ma inverter, magetsi a DC, mabatire, ndi ma circuit owongolera. Popanda iwo, kukwera kamodzi kokha kungayambitse kuwonongeka kwa insulation, kulephera kwa semiconductor, kapena kuwonongeka kosatha kwa magwiridwe antchito. Ndawona izi zikuchitika mu chitetezo cha kukwera kwa magetsi m'mafakitale komwe nthawi yogwira ntchito imasanduka nthawi yomaliza yoperekera katundu.

Kapangidwe kabwino ka DC SPD nthawi zonse kamaganizira ubwino wa nthaka, kutalika kwa chingwe, ndi malo oyika. Sindimaona chitetezo cha DC ngati chinthu chodziyimira pachokha. Chiyenera kugwira ntchito ngati gawo la dongosolo lonse lokhazikitsa nthaka ndi ma bonding.

Mtundu wachiwiri wa DC SPD za Dzuwa ndi Mphamvu

Ndikupangira ma DSPD amtundu wa 2 a DC m'malo ambiri ogawa mphamvu ya dzuwa ndi mphamvu.

Zipangizo za DC SPD Type 2 zimapangidwa kuti ziteteze makina a DC ku mphezi zomwe zimayambitsa komanso ma overvoltage osinthika m'malo ogawa magetsi.

Mu mapulojekiti anga, ma DSPD amtundu wa 2 DC ndi omwe amagwiritsidwa ntchito kwambiri. Amayikidwa pansi pa makina akuluakulu oteteza mphezi ndipo amagwira ntchito bwino pazochitika zobwerezabwereza. Mosiyana ndi zida za mtundu wa 1, amakonzedwa bwino kuti azigwiritsidwa ntchito pa ma board ogawa, mabokosi ophatikiza, ndi ma inverter inputs.

Ndimakonda chitetezo cha Mtundu 2 cha padenga la nyumba, ma PV amalonda, ndi ntchito zambiri za SPD zamafakitale. Amapereka mgwirizano wamphamvu pakati pa mulingo wa chitetezo ndi mtengo. Izi ndizofunikira kwa oyang'anira kugula omwe amafuna mitengo yodziwikiratu popanda kuwononga kudalirika.

Kuchokera pa zomwe zachitika, ma DSPD amtundu wa 2 amachepetsa kwambiri zolakwika za inverter zomwe zimasokoneza komanso kutsekedwa kosamveka bwino. Amawonjezeranso nthawi ya moyo wa zida pochepetsa kupsinjika kwamagetsi komwe kumachitika nthawi zambiri. Izi zikutanthauza kuti mtengo wotsika wokonza ndi kukhazikika kwa makina ndi wabwino.

Kufotokozera kwa DC SPD Voltage Ratings

Ndimaona zolakwika pamlingo wamagetsi nthawi zambiri kuposa cholakwika china chilichonse chosankha SPD.

Ma voltage a DC SPD ayenera kupitirira mphamvu ya DC system voltage yomwe ingatheke kuti apewe kulephera msanga komanso kutayika kwa chitetezo.

Sindisankha SPD kutengera voteji yokha. Kutentha, momwe ntchito ikuyendera, ndi kukulitsa makina onse zimakhudza kuchuluka kwa voteji yeniyeni. Mwachitsanzo, nyengo yozizira imatha kukakamiza voteji ya PV yotseguka kwambiri kuposa ma nameplate.

Umu ndi momwe ndimagwirizanirana ndi ma voltage a DC:

Kugwiritsa ntchito voltage yolondola kumatsimikizira kuti Chipangizo Choteteza Kuwonjezeka amachita zinthu modalirika pakapita nthawi m'malo molephera mwakachetechete pambuyo pa zochitika zingapo.

Kukhazikitsa kwa Pole kwa Zipangizo Zoteteza DC Surge

Nthawi zonse ndimatsimikiza kasinthidwe ka pole ndisanavomereze DC SPD iliyonse.

Kapangidwe ka ndodo ya chipangizo choteteza ma surge cha DC kamafotokoza kuchuluka kwa ma conductors omwe amatetezedwa komanso momwe mphamvu ya surge imatulutsidwira pansi.

Makina ambiri a solar amagwiritsa ntchito ma 2P DC SPDs kuti ateteze ma conductor abwino ndi oipa. Mu makina ovuta kwambiri, njira zosiyanasiyana zokhazikitsira pansi zingafunike ma pole ena. Kusankha kasinthidwe kolakwika kungapangitse kuti gawo lina la makinawo liwonekere.

Mu mapulojekiti a SPD a mafakitale, ndimafufuza kawiri kaye za grounding topology. Izi zimateteza zoopsa zobisika ndikuwonetsetsa kuti chitetezo chikugwira ntchito bwino nthawi zonse.

Kodi Chipangizo Choteteza Kuthamanga kwa AC N'chiyani?

Ndimaona chitetezo cha AC ngati gawo lachiwiri lofunika kwambiri la chitetezo.

An Chipangizo choteteza kugwedezeka kwa AC Amachepetsa mphamvu yamagetsi yosakhalitsa pa zingwe zamagetsi za AC, kuteteza katundu ndi zida zogawira kuti zisawonongeke.

Ma AC SPD amateteza ku mafunde olowera kuchokera ku gridi kapena opangidwa mkati mwa zochitika zosinthira. Mu machitidwe a dzuwa, amateteza zotulutsa za inverter, ma switchboard, ndi katundu wotsikira pansi.

Nthawi zonse ndimagwirizanitsa ma AC ndi ma DC SPD pamodzi. Chitetezo chosiyana sichigwira ntchito bwino ngati njira yogwirizana.

AC SPD ya Machitidwe Amodzi ndi Atatu a Gawo Limodzi

Ndimasintha kusankha kwa AC SPD kutengera topology ya dongosolo.

Ma AC SPD amasankhidwa malinga ndi kasinthidwe ka gawo kuti atsimikizire chitetezo chokwanira komanso chokwanira cha surge.

Machitidwe a gawo limodzi nthawi zambiri amagwiritsa ntchito makonzedwe osavuta, pomwe machitidwe a magawo atatu amafuna njira zovuta zotetezera. Ndimaganizira kwambiri za kusinthasintha ndi kukhazikika kuti ndipewe kupsinjika kosagwirizana panthawi ya zochitika za surge.

Njira imeneyi imagwira ntchito bwino kwambiri poteteza kukwera kwa mafunde m'mafakitale omwe ali ndi udindo wofanana ndi kulemera kwa katundu ndi kupitiriza kwake.

Ma Ratings ndi Makonzedwe a Voltage ya AC SPD

Nthawi zonse ndimayerekeza ma voltage a AC ndi momwe amagwirira ntchito, osati ma label okha.

Kuyeza ndi kukonza kwa ma voltage a AC SPD kumafotokoza momwe mafunde amalepheretsedwera bwino m'nyumba, m'mabizinesi, komanso m'mafakitale.

Nayi njira yosavuta yomwe ndimagwiritsa ntchito nthawi zambiri:

Kukonza kolondola kumatsimikizira kusintha kodalirika kwa mafunde ndikuletsa kukalamba msanga kwa SPD.

Kugwirizanitsa AC ndi DC SPD mu Solar Systems

Nthawi zonse ndimapanga chitetezo cha ma surge ngati njira yogwirizana.

Kugwiritsa ntchito ma AC ndi ma DC SPD pamodzi kumapanga chitetezo cha zigawo zomwe zimachepetsa magetsi otsala ndikuwonjezera kudalirika kwa dongosolo lonse.

Kugwirizanitsa kumatanthauza kuyika ma DC SPD pafupi ndi ma PV arrays ndi ma inverter, ndi ma AC SPD pamalo ogawa. Njira iyi yokhala ndi zigawo ndi yodziwika bwino pakupanga kwaukadaulo kwa surge arrester ndipo imapereka chiopsezo chochepa kwambiri cha nthawi yayitali.

Mapeto

Sankhani choyenera Chipangizo Choteteza Kuwonjezeka njira tsopano yotetezera dongosolo lanu, ndondomeko yanu, ndi ndalama zomwe mumayika nthawi yayitali.
