Kutheni ufaka i-SCB (iSurge Circuit Breaker) ngaphambili kwe-SPD (Isixhobo sokukhusela isixhobo)

Yintoni i-SCB?

I-SCB-Surge breaker breaker okanye SPD backup protector

Kutheni i-SCB?

I-SCB isombulule ngempumelelo ingxaki yehlabathi jikelele yokuqhubela phambili isixhobo sokukhusela ukungaphumeleli.

UkuSetyenziswa kweMveliso

1. Ukucinywa okukhethiweyo kokuhamba kwamandla ombane okwangoku kunye nombane okwangoku unokukhusela ngokufanelekileyo i-SPD ekujikelezeni okufutshane kunye nokujikeleza okufutshane kwe-SPD ngenxa yokuhamba okungaphaya kwamandla ombane, okukhokelela kwiingozi ezinkulu zomlilo.

2. Ukwahlulahlulahlula amandla ombane okudlulileyo kunye nombane ngoku unokukhusela ngokufanelekileyo i-SPD ekubangeleni i-voltage yokuqala ye-SPD yehle ngaphantsi kombane wokuhambisa umbane, kunye nokuhamba rhoqo kwamandla okuvuza okwenyukayo, kubangele ingozi yomlilo.

3. Xa i-SPD inombane wangoku, isixhobo sokuqhawula umbane sangaphandle asiyi kukhubeka ngengozi, ukuze ukukhuselwa kombane kwezixhobo zombane kuhlala zikwimeko esebenzayo.

Ubume be sicelo

Umkhuseli okhuselekileyo wokugcina okhuselekileyo unika ukhuseleko lobuchwephesha kwi-SPD (Isixhobo soKhuseleko soMbane) esikhusela unikezelo lwamandla kwinqanaba lokuqala, lesibini nelesithathu. Iyasebenza kwiindawo apho kufakelwe khona izixhobo zokukhusela umbane ze-SPD, ezinje ngezixhobo zamandla kulwakhiwo lwamashishini kunye noluntu, umbane, unxibelelwano, ukuthuthwa kwendlela, ipetroli kunye namanye amashishini.

Umgaqo wokusebenza

I-SCB, isixhobo sokukhuphela ngaphandle sangaphandle se-SPD, luhlobo lwezixhobo eziphuhliswa ngokwenqaku le-430.3 kwi-IEC61643-4-43: yamkela izixhobo ezifanelekileyo zokukhusela zangoku ngaphambi kwengozi ebangelwe sisekethe. Isombulula ikakhulu iingxaki ezithi xa zilandela imisinga okanye imijelo yokuvuza yenzeke kwi-SPD, i-SCB inokuhamba ngokukhawuleza, ngelixa imibane idlula, i-SCB ayikhubeki, i-SCB iqinisekisa ukuba i-SPD ayibangeli mlilo kunye nokukhuselwa kwezibane kwezixhobo kuhlala ixesha elide, ukusombulula iingxaki zokuba kukho ukukhusela okungaboniyo kwiifyuzi ezisetyenziswayo ngoku kunye neziqhekezi ezisetyenziswa njengezikhupheli zangaphandle. I-SCB zizixhobo ezifanelekileyo zokudibanisa i-SPD yohlobo lwevolthi, uhlobo lokunciphisa umda we-SPD kusetyenziswa inkqubo yombane wamandla asezantsi.

Ehlabathini lonke bathatha inxaxheba ekusombululeni ingxaki:

Xa ukutshaya kwe-SPD kusenzeka, ii-breaker zangaphandle azinqamli, kwaye xa ukunyuka kuhamba nge-SPD, ii-breakers zangaphandle zinqamla ngempazamo.

IJamani yaqhuba ulingo lombane wangoku kwiimpembelelo nakwizikrelemnqa ngo-1997. Indawo eluhlaza ithetha uqhagamshelo, indawo e-orenji ithetha ukungaqiniseki, kunye nommandla obomvu uthetha ukunqunyulwa.

I-IEC iyile yahlaziya umgangatho we-SPD. Ikomitana 37A yamisela i-Task Force 12 kwintlanganiso yase-Austria-Vienna. ukusombulula ingxaki ehambelana phakathi kwabaphuli kunye neSPD.

Amazwe amaninzi ajikeleze igama aqalise isifundo ingxaki yokonakala kwee-MOVs (i-metal oxide varistors) i-SPD.

1. Xa ukonakala kwe-SPD kwenzeka, ukubonakaliswa kweeparameter zombane kukuba ngu-U_c ixabiso liyancipha.
2. Xa u_c Ixabiso linciphisa kumandla ombane, ukuvuza okwangoku kuya kunyuka kabukhali.
3. Xa amandla ebonakala engaqhelekanga ngaphezulu kwamandla ombane, iya kubangela ukuba i-SPD iqale.
4. Xa imeko yangoku engaphezulu kwe-5A ihamba nge-SPD, isantya sombane sikhawuleza kunokuhambisa ubushushu.

Xa okwangoku ngaphezulu kwe-5A idlula kwi-SPD, inokubamba umlilo kwangoko, ke i-SPD ifuna umtshintshi otshintshayo okhupha ngokukhawuleza xa okwangoku okungaphezulu kwe-5A kudlula ukuthintela umlilo!

Ifuna ukuba xa umbane uhamba ngoku, awukhubeki, ogcina ukusebenza kakuhle emsebenzini.

Xa ukonakala kwe-SPD kwenzeka okanye ngaphambi kokuvuza okukhoyo okubangelwa ngamandla angaqhelekanga kufikelela kwi-5A, inokukhubeka ngokukhawuleza.

Yintoni enokuthi iSCB isombulule ingxaki

Ukungahambelani phakathi kwezixhobo zokukhusela umbane kunye nefuse okanye ikhefu?

Indlela yesiko kukudibanisa i-fuse okanye i-breaker kuthotho phambi kwezixhobo zokukhusela umbane, kuya kubakho izinto ezine zokungahambi kakuhle xa usenza njalo.

1. Xa umbane ukhusela izixhobo ezonakalisayo okanye kukho umbane ogqithisileyo okwenzeka kwisekethe yokuhambisa, izixhobo ezikhuselayo zombane ziya kuba kukufutshane ukujikeleziswa emhlabeni kwaye iiFyuzi okanye ii-breakers azikwazi ukunqamla ngokukhawuleza
2. Xa umbane uvela, iifyuzi okanye ii-breakers azinakuma amandla ethutyana ombane, kuba zazisetyenziselwa ukuhambisa amandla kuyilo lwangaphambili. Ke kulula ukubenza bakhubeke okanye baqhume, besenza ukuba imibane ikhuseleke ingasebenzi.
3.  Xa umbane wangoku udlula kwiziqhekezi, ixabiso eliPhezulu liphezulu kakhulu kwaye izixhobo ezikhuselekileyo zombane azinakukhusela izixhobo kakuhle.
4.  Iifusi okanye ii-breakers azinakunqamla kumbane ofakelweyo kwisiguquli. Xa isiphaluka esifutshane senzeka, abanakuphula ngokukhawuleza.

I-SCB ingasombulula iingxaki ezine ngexesha elinye

I-SCB, edityaniswe kuthotho phambi kwe-SPD isombulula iingxaki ezine ngaxeshanye.

1. Xa umbane ukhusela izixhobo ezonakalisayo okanye kukho umbane ogqithisileyo okwenzeka kwisekethe yokuhambisa, i-SCB inokukhupha unxibelelwano ngokukhawuleza ukunqanda umbane kwizixhobo ezikhuselayo ekudubuleni. Okwangoku kungaphantsi kwe-3 A.
2. Xa umbane uqhubeka, i-SCB edityaniswe kuthotho phambi kwe-SPD ayinakugcina kukhubeka kwaye akukho monakalo phantsi kombane we-100kA, ukugcina i-SPD isebenza.
3. Xa umbane ngoku udlula kwi-SCB, i-U_p Ixabiso liphantsi kakhulu, lilingana nobhedu ngobude obulinganayo.
4. Umthamo wokophuka kwe-SCB ungaphezulu kwamaqhekeza eplastiki, ukuya kuthi ga kwi-100kA.

Kukho umahluko omkhulu ngexesha kunye nokuphakama phakathi kokuhamba kwamandla okwangoku kunye nokunyuka. I-SCB isebenzisa ezi paramitha zimbini ukulawula i-electromagnets, ukufezekisa umsebenzi wokukhubeka.

1. Xa kutshintshana ukuhamba ngoku, i-electromagnet inokuhamba ngokukhetha ukunqamla okwangoku.
2. Ngenxa yokuba isantya sokukhawuleza sikhawuleza kakhulu, ukunyuka kuyaphela ngaphambi kokuba i-electromagnet ithathe inyathelo. Ke i-electromagnet ikwisimo esomeleleyo kwaye i-SCB ayikhubeki.

Umbane oshiyekileyo wee-SCB, ii-MCB kunye neeFyusi phantsi kwempembelelo yangoku
