Umahluko phakathi koMkhuseli weSurgery kunye noBambi

Izikhuseli zotyando kunye nokubamba umbane aziyonto inye.

Nangona zombini umsebenzi wokuthintela overvoltage, ingakumbi ukuthintela umbane overvoltage, kusekho iyantlukwano ezininzi isicelo.

1. Umbambeli unamanqanaba ombane amaninzi, ukusuka kwi-0.38KV ombane ophantsi ukuya kwi-500KV UHV, ngelixa abakhuseli bombane ngokubanzi banemveliso yombane ophantsi;

2. Umbambisi ufakwe kwisistim sokuqala ukukhusela ukungena ngokuthe ngqo kwamaza ombane.Umkhuseli wotyando ufakwe ikakhulu kwinkqubo yesibini.Emva kokuba umbane obambe umbane uphelise ukungena ngokuthe ngqo kwamaza ombane, umbambeli wombane awuphelisi umbane wombane.Imilinganiselo eyongezelelweyo

I-3, umbambisi kukukhusela izixhobo zombane, kwaye umkhuseli wokunyuka ukhusela kakhulu izixhobo ze-elektroniki okanye izixhobo;

4. Ngenxa yokuba umbane obamba umbane uqhagamshelwe kwisistim sokuqala sombane, kufuneka ube nokusebenza okwaneleyo kwe-insulation yangaphandle, kwaye ubungakanani bembonakalo bukhulu kakhulu, kwaye umkhuseli wokunyuka ungenziwa omncinci ngenxa yombane ophantsi.

Umahluko phakathi komkhuseli wotyando kunye nesibambisi:

1. Intsimi yesicelo inokwahlulwa ukusuka kwinqanaba lombane.I-voltage elinganisiweyo yombambeli ngu-<3kV ukuya kwi-1000kV, i-voltage ephantsi 0.28kV, 0.5kV.

I-voltage elinganisiweyo yomkhuseli wokunyuka yi-k1.2kV, 380, 220 ~ 10V ~ 5V.

I-2, into yokukhusela ihluke: umbambeli kukukhusela izixhobo zombane, kwaye umkhuseli we-SPD wokunyuka ngokuqhelekileyo ukukhusela i-loop yesiginali yesibini okanye ekupheleni kwesixhobo sombane kunye nezinye iilophu zombane.

3. Inqanaba le-insulation okanye inqanaba loxinzelelo lihlukile: umgangatho wokumelana nombane wezixhobo zombane kunye nezixhobo zombane awukho umyalelo wobukhulu, kwaye i-voltage eseleyo yesixhobo sokukhusela i-overvoltage kufuneka ihambelane nomgangatho wokumelana nombane wento yokukhusela.

4. Izikhundla ezahlukeneyo zokufakela: Umbambeli ufakwe ngokubanzi kwisistim yokuthintela ukungena ngokuthe ngqo kwamaza ombane kunye nokukhusela imigca ephezulu kunye nezixhobo zombane.Umkhuseli wokunyuka kwe-SPD ufakwe kwinkqubo yesibini, ephelisa amaza ombane kwisibambi.Emva kokungena ngokuthe ngqo, okanye umbambisi akanayo imilinganiselo eyongezelelweyo yokuphelisa umbane wombane;ngoko ke, umbambi ufakwe kumgca ongenayo;i-SPD ifakwe kwi-outlet yokugqibela okanye isiphaluka somqondiso.

5. Umthamo ohlukeneyo wokuhamba: isibambisi sombane ngenxa yokuba indima ephambili kukuthintela ukugqithiswa kombane, ngoko ke umthamo wayo wokuhamba uhambelana mkhulu;kunye nezixhobo ze-elektroniki, inqanaba layo lokugquma lincinci kakhulu kunezixhobo zombane ngokwengqiqo jikelele, kuyimfuneko kwi-SPD kwi-overvoltage yombane Ikhuselwe ngokugqithiswa kokusebenza, kodwa amandla ayo okuhamba-hamba ngokubanzi amancinci.(I-SPD ngokuqhelekileyo ekupheleni kwaye ayiyi kudibaniswa ngokuthe ngqo kumgca ophezulu. Emva komda wangoku wenqanaba eliphezulu, umbane wombane ukhawulelwe kwixabiso eliphantsi, ukwenzela ukuba i-SPD ene-flow flow encinci inokukhusela ngokupheleleyo. Ixabiso alibalulekanga, into ebalulekileyo luxinzelelo olushiyekileyo.)

6. Amanye amanqanaba e-insulation, ugxininiso lweeparamitha, njl njl.

7. Umkhuseli wokunyuka ufanelekile ukukhuselwa kakuhle kwenkqubo yokubonelela umbane ophantsi.Iintlobo ezahlukeneyo zombane ze-AC/DC zinokukhethwa ngokweenkcukacha ezahlukeneyo.Umkhuseli wokunyuka kwamandla unomgama omkhulu ukusuka kumkhuseli wokuqhubela phambili kwisiphelo, ukwenzela ukuba isekethe ithandeke kwi-oscillating overvoltage okanye enye i-over-voltage.Ukukhuselwa kwamandla afanelekileyo kwizixhobo ze-terminal, ezidityaniswe nomkhuseli we-pre-stage surge, umphumo wokukhusela ungcono.

8. Izinto eziphambili zokubamba ininzi i-zinc oxide (enye ye-metal oxide varistor), kunye neyona nto iphambili yomkhuseli wokunyuka ihluke ngokwezinga lokuchasana kunye nokukhusela ukuhlelwa (IEC61312), kunye noyilo luyilo. ezahlukeneyo.Izibambi zombane eziqhelekileyo zichaneke ngakumbi.

9. Ukuthetha ngobuchwephesha, umbambisi akafikeleli kwinqanaba lomkhuseli wokunyuka ngokwexesha lokuphendula, umphumo wokunciphisa uxinzelelo, umphumo wokukhusela obanzi, kunye neempawu zokuguga.
