Umehluko phakathi koMvikeli Wokuhlinza Nokuboshwa

Abavikeli abahlinzayo nabavimbela umbani akuyona into efanayo.

Nakuba zombili zinomsebenzi wokuvimbela ukugcwala kwe-voltage, ikakhulukazi ukuvimbela ukugcwala kombani, kusenomehluko omningi ekusetshenzisweni.

1. Isibambisi sinamazinga kagesi amaningi, asukela ku-0.38KV kagesi aphansi kuya ku-500KV UHV, kuyilapho izivikeli zokuhlinza ngokuvamile zinemikhiqizo yamandla kagesi aphansi;

2. Isiboshwa sifakwe ohlelweni oluyinhloko ukuvimbela ukungena okuqondile kwamagagasi ombani.Isivikeli sokuhlinza sifakwa kakhulu ohlelweni lwesibili.Ngemva kokuba isivimbeli sombani siqede ukungena okuqondile kwamaza ombani, isibambisi sombani asiwuqedi umbani.Izinyathelo ezengeziwe

3, isibambi siwukuvikela okokusebenza kukagesi, futhi isivikelo sokuhlinza ngokuvamile sivikela amathuluzi kagesi noma amathuluzi;

4. Ngenxa yokuthi isibambisi sombani sixhunywe ohlelweni oluyisisekelo lukagesi, kufanele lube nokusebenza okwanele kokufakwa kwangaphandle, futhi ubukhulu bokubukeka bukhulu ngokuqhathaniswa, futhi isivikeli sokuhlinzwa singenziwa sibe sincane ngenxa ye-voltage ephansi.

Umehluko phakathi kwesivikeli sokuhlinza kanye nesibambisi:

1. Inkambu yesicelo ingahlukaniswa kusuka ezingeni le-voltage.I-voltage elinganiselwe yesibambi ingu-<3kV kuya ku-1000kV, i-voltage ephansi 0.28kV, 0.5kV.

I-voltage elinganiselwe yesivikeli sokuhlinza yi-k1.2kV, 380, 220~10V~5V.

2, Into yokuvikela ihlukile: isibambi siwukuvikela okokusebenza kukagesi, futhi isivikeli sokuhlinza se-SPD sivamise ukuvikela iluphu yesiginali yesibili noma ekupheleni kwe-instrumentation kagesi namanye amaluphu okuphakela amandla.

3. Izinga le-insulation noma izinga lokucindezela lihlukile: izinga le-voltage elimelana lezinto zikagesi kanye nempahla kagesi aliyona i-oda lobukhulu, futhi amandla kagesi ayinsalela edivayisi yokuvikela ukugeleza kwe-overvoltage kufanele afane neleveli yokumelana ne-voltage yento yokuvikela.

4. Izikhundla ezihlukene zokufaka: Isibambisi ngokuvamile sifakwa ohlelweni lokuvimbela ukungena okuqondile kwamagagasi ombani futhi kuvikelwe imigqa engaphezulu kanye nemishini kagesi.Umvikeli ohlinzayo we-SPD ufakwe ohlelweni lwesibili, oluqeda amaza ombani ku- arrester.Ngemva kokungena okuqondile, noma umboshwa akanazo izinyathelo ezengeziwe zokuqeda igagasi lombani;ngakho-ke, isibambisi sifakwe kulayini ongenayo;i-SPD ifakwe ekugcineni kwe-outlet noma i-signal circuit.

5. Umthamo wokugeleza ohlukile: isibambisi sombani ngoba indima eyinhloko ukuvimbela ukugcwala kombani, ngakho-ke umthamo wayo wokugeleza umkhulu;kanye nemishini ye-elekthronikhi, izinga layo lokufakelwa lincane kakhulu kunemishini kagesi ngomqondo ojwayelekile, kuyadingeka ukuba i-SPD ku-overvoltage yombani Ivikelwe ngokusebenza ngokweqile, kodwa amandla ayo okugeleza ngokuvamile mancane.(I-SPD ngokuvamile isekupheleni futhi ngeke ixhunywe ngokuqondile emgqeni ongaphezulu. Ngemuva komkhawulo wamanje wesiteji esiphezulu, umbani wokukhanya ukhawulelwe inani eliphansi, ukuze i-SPD enekhono lokugeleza elincane ingavikela ngokugcwele. ukugeleza. Inani alibalulekile, into ebalulekile ingcindezi eyinsalela.)

6. Amanye amazinga okufakelwa, ukugxila kwemingcele, njll. nakho kunomehluko omkhulu.

7. Umvikeli ohlinzayo ufanelekile ukuvikela okuhle kwesistimu yokuhlinzeka amandla kagesi aphansi.Amandla kagesi e-AC/DC ahlukahlukene angakhethwa ngokuya ngemininingwane ehlukene.Isivikeli sokuhlinza samandla sinebanga elikhulu ukusuka kusivikeli sokuhlinza esisekupheleni, ukuze isekethe ithambekele ekutheni i-oscillating overvoltage noma enye i-over-voltage.Ukuvikelwa okuhle kokusebenza kwamandla kwemishini yokugcina, kuhlanganiswe nesivikeli sokuhlinza sangaphambi kwesiteji, umphumela wokuvikela ungcono.

8. Impahla eyinhloko yesiboshwa ngokuvamile i-zinc oxide (enye ye-metal oxide varistor), futhi impahla eyinhloko yesivikeli sokuhlinza ihlukile ngokuya ngezinga lokulwa nokuhlinzwa kanye nokuvikelwa kwezigaba (IEC61312), futhi umklamo ezahlukene.Izibambisi zombani ezijwayelekile zinembe kakhulu.

9. Uma sikhuluma ngobuchwepheshe, isibambisi asifinyeleli izinga lesivikeli sokuhlinza ngokwesikhathi sokuphendula, umphumela wokunciphisa ingcindezi, umphumela wokuvikela ophelele, nezici zokulwa nokuguga.
