Kutheni le nto uKhuseleko lweSekethe ye-DC luba lubalulekileyo kwikamva leeNkqubo zaMandla?

Ishishini lamandla lehlabathi liya lixhomekeke ngakumbi kumbane othe ngqo. I-Solar photovoltaic arrays, iinkqubo zokugcina amandla ebhetri, izikhululo zokutshaja iimoto zombane, izixhobo zonxibelelwano, kunye namaziko edatha zonke ziqulethe amacandelo abalulekileyo e-DC. Njengoko ezi zicelo zandisa, ukukhuselwa kweesekethe zihamba ukusuka kwicandelo elixhasayo ukuya kwindawo ephakathi yokhuseleko lwenkqubo. ADC wesekethe umaphulikufuneka uqhawule umsinga ongaqhelekanga ngokukhawuleza nangokukhuselekileyo, ukunciphisa umonakalo kwiintambo, iziguquli, iibhetri, kunye nezixhobo eziqhagamshelweyo.

Ukuphazamisa i-DC yahlukile ngokobuchwephesha ekuphazamiseni i-AC. Kwisekethe ye-AC, okwangoku ngokwemvelo iwela i-zero amaxesha amaninzi ngesekhondi, enceda ukucima i-arc yombane. I-DC ayinayo i-zero yendalo yokuwela, ngoko ke i-arc inokuhlala izinzile emva kokuba abafowunelwa bahlukene. Izaphuli ezilungiselelwe i-DC ke ngoko zifuna ulwakhiwo olufanelekileyo loqhagamshelwano, ii-arc chutes, ilungiselelo lokuvuthela ngomagnetic, imigama yokwaleka, kunye nolungelelwaniso lweengcingo. I-AC breaker akufuneki kucingelwe ukuba ifanelekile kwinkonzo ye-DC kuba ireyithingi yayo yangoku ibonakala ngokwaneleyo.

Enye indlela ecacileyo yoshishino kukuhamba ukuya kumandla ombane aphezulu kunye nokuxinana kwamandla amakhulu. Umbane ophezulu we-DC unokunciphisa okwangoku kumbane ofanayo ogqithisiweyo, unceda ilahleko ye-conductor ephantsi kunye neemfuno zentambo. Nangona kunjalo, yenza ulungelelwaniso lwe-insulation kunye nokuphazamiseka kwe-arc kufuneke ngakumbi. Ukukhetha imveliso kufuneka kuthathelwe ingqalelo amandla ombane osebenzayo, olwenziwayo lwangoku, inani leepali, umthamo wokuqhawula ixesha elifutshane, indawo yokusetyenziswa, kunye nendlela yoqhagamshelo oluchaziweyo lomenzi. Iimfuno zePolarity zibaluleke ngakumbi kuyilo lwe-DC breaker.

Omnye umkhwa lunxulumano olusondeleyo phakathi kwezaphuli kunye nokubeka iliso nge-elektroniki. Iinkqubo zamandla zale mihla ziya zisanda zisebenzisa izinzwa, izilawuli, kunye nothungelwano lonxibelelwano ukuchonga ukushisa okugqithisileyo, ukugcwala, iziphene zokugquma, kunye neepatheni zokusebenza ezingaqhelekanga. Ukhuseleko lomatshini luhlala lubalulekile, kodwa luba yinxalenye yolwakhiwo olubanzi lokhuseleko olunokubandakanya iifuse, izixhobo zokukhusela ezongezelelekileyo, abafowunelwa, izixhobo zokubeka iliso kwi-insulation, kunye neenkqubo zolawulo lwebhetri. Ukukhethwa phakathi kwezixhobo eziphezulu kunye nezisezantsi zikwafumana ingqwalasela engakumbi ngenxa yokuba ukuvalwa ngokungeyomfuneko kunokuchaphazela umtya welanga, i-rack yokugcina, ikhabhinethi yokutshaja, okanye inkqubo yoshishino.

I-DAM3DC-250 iboniswe nguShanghai Dada Electricibonisa uhlobo olubunjiweyo lwe-DC breaker esetyenziswa kunikezelo oluphezulu lwangoku. Iimpawu ezibonakalayo zibonisa umbane olinganisiweyo we-250 A, i-DC ye-voltage ye-1000 V, amandla okuphuka kwe-20 kA, kunye noyilo lweepoleni ezimbini. Ezi xabiso zichaza uluhlu olucetywayo lombane; aziqinisekisi ngokwazo ukufaneleka kofakelo ngalunye. Iinjineli kusafuneka ziqinisekise elona nqanaba lesekethe emfutshane, ubungakanani bomqhubi, ubushushu be-ambient, iimeko ezivalelekileyo, iimpawu zomthwalo, umphakamo wofakelo, imigangatho esebenzayo, kunye nolungelelwaniso lokhuseleko olufunekayo.

Kubasebenzisi bokugqibela, iileyibhile ezicacileyo kunye namaxwebhu axabiseke ngokulinganayo, kuba ukufakela okuchanekileyo, ukugcinwa, kunye nezigqibo zokutshintsha zixhomekeke ekwazini ukulinganisa okuqinisekisiweyo kwesixhobo kunye nemida kwinkonzo.

Ukujonga phambili, abathengi baya kubeka ugxininiso olukhulu ekuqinisekisweni kwesicelo esithile kunokukhetha izixhobo ngokulinganisa ngoku kuphela. Ukhuseleko oluthembekileyo lwe-DC luxhomekeke ekufaniseni amandla ombane achanekileyo, uphazamiseko olwaneleyo lokukwazi, ulungelelwaniso olufanelekileyo lwepali, ufakelo olulawulwayo, kunye nokuhlolwa kwamaxesha athile. Njengoko isizukulwana esivuselelekayo, ukugcinwa, kunye nothutho olunombane luqhubeka nokuphuhliswa, ukuqonda ezi ziseko kuya kunceda abaqulunqi benkqubo banciphise umngcipheko kwaye bakhe uthungelwano lwe-DC oluthembekileyo.
