Imigaqo kunye neenkcazo
Amandla ombane u-UN
Amandla ombane amela amandla ombane wenkqubo eza kukhuselwa. Ixabiso levolthi yamagama aqhelekileyo lihlala lisebenza njengohlobo lokhetho lwezixhobo zokukhusela izixhobo zetekhnoloji yolwazi. Kuboniswa njengexabiso le-rms kwiinkqubo ze-ac.
Ubuninzi bokusebenza kwamandla ombane uC
Amandla ombane aphezulu aqhubekekayo (amandla ombane avumelekileyo aphezulu) lixabiso leerms zamandla ombane aphezulu anokuqhagamshelwa kwiziphelo ezihambelana noko kwesixhobo sokukhusela ngexesha lokusebenza. Owona mbane ubuninzi ekubanjweni kwimeko echaziweyo engaqhubiyo, ethi ibuyise umbanjwa abuyele kweli lizwe emva kokukhubeka kunye nokukhululwa. Ixabiso le-UC lixhomekeke kumandla ombane wenkqubo eza kukhuselwa kunye neenkcukacha zomfaki (IEC 60364-5-534).
Ukukhutshwa ngegama ngoku In
Ukukhutshwa kwangoku ngegama kukuphakama kwexabiso le-8/20 μs yangoku apho isixhobo esikhuselekileyo sokukhusela silinganiswe kwinkqubo ethile yovavanyo kwaye isixhobo esikhuselayo sinokukhupha amatyeli aliqela.
Ukukhutshwa okuphezulu kwangoku Imax
Elona xesha liphezulu lokukhutshwa ngoku lelona xabiso liphezulu le-8/20 μs yokunyanzeliswa kwesixhobo ngoku esinokuthi sikhuphe ngokukhuselekileyo.
Umbane unyanzelisa ngoku ukuba mnaimp
Umbane oshukumisayo wangoku ngumgangatho omiselweyo wejika yangoku kunye nefom ye-10/350 μs. Iiparameter zayo (ixabiso lencopho, intlawulo, amandla athile) kulingisa umthwalo obangelwe yimibane yendalo. Umbane wangoku kunye nokudityaniswa kwababanjiweyo kufuneka babenakho ukukhupha loo mibane yokuqhubela umbane amatyeli aliqela ngaphandle kokutshatyalaliswa.
Ukukhutshwa okupheleleyo okwangoku Ililonke
Okwangoku kuhamba nge-PE, i-PEN okanye unxibelelwano lomhlaba lwe-SPD ye-multipole ngexesha lovavanyo olupheleleyo lwangoku. Olu vavanyo lusetyenziselwa ukumisela umthwalo opheleleyo ukuba ngoku kuhamba ngokuhamba ngeendlela ezininzi zokukhusela ze-SPD ezininzi. Le parameter ithatha isigqibo malunga nomthamo opheleleyo wokukhutshwa oqhutywa ngokuthembekileyo lixa lomntu lowo
iindlela ze-SPD.
Inqanaba lokukhusela i-Voltage UP
Inqanaba lokhuselo lwevolthi yesixhobo sokukhusela elona xabiso liphezulu kwangoko levolthi kwiitheminali zesixhobo sokukhusela, esimiselwe kuvavanyo oluqhelekileyo:
-Umbane unyanzelisa amandla ombane 1.2 / 50 μs (100%)
Umbane weSparkover ngenqanaba lokunyuka kwe1kV / μs
Umlinganiso wevolthi yomda kwindawo yokukhutshwa ngegama ngokun
Inqanaba lokhuselo lwevolthi libonisa ukubanakho kwesixhobo esikhuselayo sokukhawulela ukunciphisa ama-surges kwinqanaba lentsalela. Inqanaba lokhuselo lwevolthi lichaza indawo yofakelo ngokubhekisele kudidi lwevoltage ngokwe-IEC 60664-1 kwiinkqubo zonikezelo lwamandla. Ukuze izixhobo zokukhusela zisetyenziswe kwiinkqubo zetekhnoloji yolwazi, inqanaba lokukhuselwa kwamandla ombane kufuneka lilungelelaniswe nenqanaba lokhuselo lwezixhobo eziza kukhuselwa (IEC 61000-4-5: 2001).
Ireyithi yangoku yesekethe emfutshaneSCCR
Elona xesha liphezulu langoku lokujikeleza okwangoku kwinkqubo ye-SPD, kwi
Ukudityaniswa kwesixhobo sokuqhawula unxibelelwano esikhethiweyo, kukaliwe
Ukujikeleza okufutshane kukumelana namandla
Ukuma okufutshane kokuma kwesekethe lixabiso lamandla ombane anokuhamba ngesantya esinezixhobo eziphathwayo ngesixhobo sokukhusela xa isixhobo sokugcina sokugcina siphezulu siqhagamshelwe phezulu.
Ukulinganisa okufutshane-kwesekethe II-SCPV ye-SPD kwinkqubo ye-photovoltaic (PV)
Ubuninzi be-short-circuit yangoku engathintekiyo apho i-SPD, iyodwa okanye ngokudibeneyo nezixhobo zayo zokucinywa, iyakwazi ukumelana nayo.
Ukugqithisa okwethutyana (TOV)
Ukugqithisa okwethutyana kunokubakho kwisixhobo sokukhusela ixesha elifutshane ngenxa yesiphoso kwinkqubo yamandla ombane aphezulu. Oku kufuneka kwahlulwe ngokucacileyo kwithutyana elibangelwe kukubetha kombane okanye ukusebenza kokutshintsha, okungagqithanga kangange-1 ms. Ubungakanani beUT kunye nexesha lokudlula kwexeshana kuchaziwe kwi-EN 61643-11 (200 ms, 5 s okanye 120 min.) Kwaye kuvavanywa ngokukodwa ii-SPD ezifanelekileyo ngokokumiswa kwenkqubo (TN, TT, njl.). I-SPD inokuthi a) isilele ngokuthembekileyo (ukhuseleko lwe-TOV) okanye b) ibe kukunganyangeki kwi-TOV (TOV ukumelana), nto leyo ethetha ukuba isebenza ngokupheleleyo ngexesha kwaye ilandela ukonyuka okwethutyana.
Ukulayishwa okwangoku okukhoyo (okwangoku)L
Okwangoku umthwalo okhoyo ngoku lelona xesha liphezulu livumelekileyo ngoku lokusebenza nelinokuhamba ngokusisigxina kwiitheminali ezihambelanayo.
Umqhubi okhuselayo ngoku u-IPE
Umqhubi okhuselayo okwangoku okwangoku ohamba ngonxibelelwano lwe-PE xa isixhobo sokukhusela sixhunyiwe kumandla ombane oqhubekayoC, ngokwemiyalelo yofakelo kwaye ngaphandle kwabasebenzisi becala lomthwalo.
I-fuse-side overcurrent protection / arrester fuse fuse
Isixhobo sokukhusela ngaphezulu (umz. I-fuse okanye isekethe yesekethe) ebekwe ngaphandle kwendawo yokubamba kwicala lokungenisa amandla ukuphazamisa isantya samandla silandela esikhoyo kwangoko xa amandla okophula isixhobo sokukhusela edlulile. Akukho fuseyus yokuncedisa eyongezelelweyo ifunwayo kuba i-backup fuse sele idityaniswe kwi-SPD (jonga icandelo elifanelekileyo)
Uluhlu olusebenzayo lobushushu TU
Uluhlu lobushushu obusebenzayo lubonisa uluhlu lwezixhobo ezinokusetyenziswa. Kwizixhobo ezingazifudumezeliyo, ilingana noluhlu lwamaqondo obushushu. Ukunyuka kwamaqondo obushushu kwezixhobo zokuzifudumeza akufuneki kudlule kwelona xabiso liphezulu libonisiweyo.
Ixesha lokuphendula tA
Amaxesha okuphendula ubukhulu becala abonakalisa ukusebenza kwempendulo yezinto ezikhuselweyo ezisetyenziswa ekubanjweni. Kuxhomekeke kwinqanaba lokunyuka kwe-du / dt yombane wempembelelo okanye i-di / dt yempembelelo yangoku, amaxesha okuphendula anokuhluka ngaphakathi kwemida ethile.
Unqanyuli
Izixhobo zokukhusela ukusetyenziswa kweenkqubo zonikezelo lwamandla ezixhotyiswe
ii-resistors ezilawulwa ngevolthi (varistors) ubukhulu becala zibonisa isixhobo sokudibanisa esisebenza ngokudibeneyo esikhupha isixhobo sokukhusela isixhobo kwimithambo yeengcingo kwimeko yomthwalo omninzi kwaye sibonisa imeko yokusebenza. Isikhupheli-siphenduli siphendula "kubushushu obukhoyo ngoku" obuveliswe yi-varistor egcweleyo kwaye sikhuphe isixhobo sokhuselo esivela kwiimitha xa kubushushu obugqithileyo. I-disconnector yenzelwe ukunqamla isixhobo esikhuselweyo sokuzikhusela ngexesha lokukhusela umlilo. Ayenzelwanga ukuqinisekisa ukukhuselwa kunxibelelwano olungqalileyo. Umsebenzi wezixhobo zokuqhawula izixhobo ezishushu zinokuvavanywa kusetyenziswa ukulayishwa okungaphezulu / ukuguga kwababanjiweyo.
Umqondiso wokubonisa kude
Umnxibelelanisi osayina ekude uvumela ukujonga ngokulula okukude kunye nokubonisa imeko yesixhobo. Inika isiphelo sesiphelo sepali ezintathu ngohlobo lonxibelelwano oludadayo. Olu nxibelelwano lunokusetyenziswa njengekhefu kunye / okanye unxibelelane kwaye lunokudityaniswa ngokulula kwinkqubo yolawulo lokwakha, umlawuli wekhabhathi ye switchgear, njl.
Ukubanjwa kwe-N-PE
Izixhobo zokukhusela ezenzelwe ngokukodwa ukufakela phakathi komqhubi we-N kunye ne-PE.
Umdibaniso wamaza
Umdibaniso wokudibanisa uveliswa ngumvelisi we-hybrid (1.2 / 50 μs, 8/20 μs) nge-impedance yentsomi ye-2 Ω. Umbane wesekethe ovulekileyo wale jeneretha kubhekiswa kuwo njenge-UOC. I-UOC sisalathiso esikhethwayo sohlobo lwe-3 ekubanjweni kuba kuphela aba babanjiweyo banokuvavanywa ngokudityaniswa kwamaza (ngokwe-EN 61643-11).
Umgangatho wokukhusela
Idigri yokhuseleko ye-IP iyahambelana necandelo lokhuseleko elichazwe kwi-IEC 60529.
Ibala lexesha
Uluhlu lwamaxesha lumela uluhlu lokuhambisa okanye ukunqunyulwa kwesantya sokubanjwa ngokuxhomekeke kwiimpawu ezichaziweyo zokuncitshiswa.
Kuya kufuneka isekwe kubungakanani beodolo.
