Wige ibijyanye no kuvugurura UL 1449 yo kwikingira (SPDS) Ibipimo, byongeraho ibisabwa byibizamini kubicuruzwa byigana ibidukikije, cyane cyane ukoresheje ubushyuhe buhoraho nubushuhe. Wige icyo kuba umurinzi ni, kandi mbega ibidukikije bitose.
Kwirinda (ibikoresho byo gukingira bikinga, spds) byahoze bifatwa nkikinzi cyingenzi kubikoresho bya elegitoroniki. Barashobora gukumira imbaraga zanduzaga n'amashanyarazi, kugirango ibikoresho birinzwe bitazangizwa nubukungu butunguranye. Umurinzi wongeyeho arashobora kuba igikoresho cyuzuye cyateguwe mu bwigenge, cyangwa gishobora gukorerwa nkibigize kandi bishyirwa mumashanyarazi ya sisitemu yamashanyarazi.
Nkuko byavuzwe haruguru, kubaga byo kubaga bikoreshwa muburyo butandukanye, ariko burigihe banenga cyane mugihe bigeze kumikorere yumutekano. UL 1449 Ibipimo nigipimo gisanzwe ko abakora imyitozo muri iki gihe bamenyereye mugihe basaba isoko ryisoko.
Hamwe no kwiyongera kw'ibikoresho bya elegitoronike n'ibikoresho byayo n'ibisabwa mu nganda n'ibyinshi, nk'itara ry'imihanda, amatara, 5G, Amashanyarazi n'amatora yo kwirwanaho no guteza imbere ibinyabiziga kandi birumvikana nabyo birakenewe Gukomeza kugendana nibihe kandi ukomeze kuvugururwa.
Igisobanuro cyo kunyuranya
Yaba NFPA 70 yishyirahamwe ryigihugu ririnze umuriro (NFPA) cyangwa Kode y'igihugu y'igihugu (NEC), "ahantu hato" byasobanuwe neza ku buryo bukurikira:
Ahantu arinzwe nikirere kandi ntabwo byibazwe hamwe namazi cyangwa izindi mazi ariko ugakurikiza impamyabumenyi ziciriritse.
By'umwihariko, amahema, ibaraza rifunguye, no munsi yububiko bwa firigo cyangwa ububiko bwa firigo, nibindi, ni ahantu heza "muri code.
Iyo umurinzi uhari (nka varustor) yashyizwe mubikorwa byanyuma, birashoboka cyane kuko ibicuruzwa byarangiye cyangwa bikoreshwa mubidukikije hamwe nibidukikije nkibidukikije, kwiyongera Umurinzi niba ashobora kuzuza ibipimo byumutekano mubidukikije rusange.
Ibisabwa byo gusuzuma ibicuruzwa mubidukikije byisukuye
Ibipimo byinshi bisaba ko ibicuruzwa bigomba kurenga urukurikirane rwibizamini byizewe kugirango hamenyekane imikorere mugihe cyubuzima bwibicuruzwa, nkubushyuhe bwinshi nubushyuhe bwinshi, kunyeganyega no guta ibintu byibizamini. Kubizamini birimo ibidukikije byigana, ubushyuhe buringaniye nubushyuhe buzakoreshwa nkisuzuma rikuru, cyane cyane ubushyuhe / 85% ") muri ibyo bipimo bibiri by'ibipimo.
Ubushyuhe buri gihe nubushyuhe bugamije kwihutisha ubuzima bwibicuruzwa binyuze muburyo bwo kugerageza. Irashobora gusuzuma neza ubushobozi bwo kurwanya ibicuruzwa, harimo no gusuzuma niba ibicuruzwa bifite ibiranga ubuzima burebure no gutakaza bike mubidukikije bidasanzwe.
Twakoze ubushakashatsi ku bibazo by'ibibazo, kandi ibisubizo byerekana ko umubare munini wibicuruzwa bitanga umusaruro kubushyuhe nubuswa bwo kurinda ubushyuhe nibigize abarindwa bikoreshwa imbere, ariko usanzwe asuzuma abarinzi nibigize Bihuye rero, uwabikoze agomba kuyobora ibizamini byinyongera nyuma yo kubona UL 1449 icyemezo; Niba kandi raporo yicyemezo cya gatatu yishyaka isabwa, bishoboka byimikorere yavuzwe haruguru bizagabanuka. Byongeye kandi, mugihe ibicuruzwa byanyuma bireba icyemezo cya UL, bizahura nibibazo byerekana ko raporo y'icyemezo ya muntu yakoresheje mu gihe cy'ibidukikije. Birasabwa.
Twumva ibikenewe byabakiriya kandi twiyemeje gufasha abakiriya gukemura ingingo zububabare zahuye nibikorwa nyabyo. UL yatangije gahunda yo kuvugurura 1449.
Ibisabwa bisabwa byongerewe kurwego
UL 1449 Standard isanzwe yongeyeho ibizamini bisabwa kubicuruzwa ahantu hatose. Abakora barashobora guhitamo kongeramo iki kizamini gishya kurubanza rwikizamini mugihe basaba icyemezo cya UL.
Nkuko byavuzwe haruguru, ikibuga cyibidukikije gitose cyerekana cyane cyane ubushyuhe buhoraho nubushuhe. Ibikurikira byerekana uburyo bwikizamini kugirango ugenzure aho variated (mow) / gusohora gaze umuyoboro (GDT) kubipimo byabidukikije bitose:
Ibyitegererezo byikizamini bizabanza gukorerwa ikizamini cyo gusaza mubushyuhe bwo hejuru nubushuhe buke kumasaha 1000, hanyuma valtage ya varustor cyangwa gusenyuka voltage yagereranijwe no kwemeza niba ibigize uburinzi bwo kwiyongera bishobora Iheruka igihe kirekire mubihe bihebuje, biracyakomeza imikorere yambere yo kurinda.
