Iimpawu Zababanjwa Besiqhelo

1. Umthamo wangoku we-zinc oxide arrester mkhulu
Oku kubonakala kakhulu kubuchule bezixhobo zokuthintela umbane bokufunxa ii-overvoltages ezahlukeneyo zombane, ii-overvoltages ze-power frequency transient voltages, kunye nee-overvoltages zokusebenza. Umthamo wokuhamba kwangoku we-zinc oxide arrester eveliswa yiChuantai uhlangabezana ngokupheleleyo okanye udlule iimfuno zemigangatho yesizwe. Izalathisi ezifana nenqanaba lokukhupha umgca, umthamo wokungenisa amandla, ukunyamezelana kwempembelelo yamandla aphezulu kwi-4/10 nanosecond, kunye nomthamo wamandla wamanzi wesikwere se-2ms zifikelele kwinqanaba eliphambili lasekhaya.

2. Iimpawu zokhuseleko ezigqwesileyo ze-zinc oxide arresters
I-Zinc oxide arrester yimveliso yombane esetyenziselwa ukukhusela izixhobo ezahlukeneyo zombane kwinkqubo yamandla kumonakalo we-overvoltage, kwaye isebenza kakuhle ekukhuseleni. Ngenxa yokuba uphawu lwe-volt-ampere olungelulo ulayini lwepleyiti yevalvu ye-zinc oxide lulungile kakhulu, kangangokuba kuphela amakhulu ambalwa e-microampere current anokudlula phantsi kwe-voltage eqhelekileyo yokusebenza, kulula ukuyila isakhiwo esingenazikhewu, ukuze sibe nokusebenza kakuhle kokukhusela, ubunzima obuphantsi, kunye nobukhulu obuncinci. Xa i-over-voltage ihlasela, umbane ohamba kwipleyiti yevalvu uyanda ngokukhawuleza, kwaye kwangaxeshanye ubukhulu be-over-voltage buncitshisiwe, kwaye amandla e-over-voltage ayakhululwa. Emva koko, ipleyiti yevalvu ye-zinc oxide ibuyela kwimeko yokuxhathisa okuphezulu, ukuze inkqubo yamandla isebenze ngokuqhelekileyo.

3. Ukusebenza kokutywina kwe-zinc oxide arrester kulungile
Into yokubamba isebenzisa ijakethi edityanisiweyo esemgangathweni ophezulu esebenza kakuhle kwaye ingenamoya, kwaye ilinganisa ucinezelo lweringi yokutywina kunye nokongeza i-sealant. Ijakethi yeseramikhi isetyenziswa njengezinto zokutywina ukuqinisekisa ukutywina okuthembekileyo kunye nokusebenza okuzinzileyo kwe-barrier.

4. Iimpawu zoomatshini ze-zinc oxide arresters
Ngokuyintloko qwalasela ezi zinto zintathu zilandelayo:
⑴ Amandla enyikima;
⑵Uxinzelelo lomoya oluphezulu olusebenza kwi-arrester
⑶ Isiphelo esiphezulu se-arrester sinoxinzelelo oluphezulu oluvumelekileyo lwentambo.

5. Ukusebenza kakuhle kokucoca i-zinc oxide arrester
Isithinteli se-zinc oxide esingenazikhewu sinokumelana nongcoliseko oluphezulu.
Inqanaba langoku lomgama we-creepage elichazwe ngumgangatho wesizwe ngulo:
⑴Udidi II indawo yongcoliseko oluphakathi: umgama ohambahambayo yi-20mm/kv
Indawo yongcoliseko olunzima kwinqanaba le-3: umgama ohambahambayo yi-25mm/kv
⑶ Ibanga lesi-IV, indawo enongcoliseko olukhulu kakhulu: umgama ohambahambayo yi-31mm/kv

6. ukuthembeka okuphezulu kokusebenza kwe-zinc oxide arresters
Ukuthembeka kokusebenza kwexesha elide kuxhomekeke kumgangatho wemveliso kunye nokuba ukukhethwa kwemveliso kufanelekile na. Umgangatho weemveliso zayo uchaphazeleka kakhulu zezi zinto zintathu zilandelayo:
A. Ukuqondakala kolwakhiwo lulonke lomntu obambeleyo;
Iimpawu ze-B Volt-ampere kunye neempawu zokumelana nokuguga kweevalvu ze-zinc oxide
C Ukusebenza kokutywina komthinteli.

7. Ukunyamezelana kwamaza ombane
Ngenxa yezizathu ezahlukeneyo ezifana nokumisa isiseko sesigaba esinye, isiphumo somthamo wentambo ende kunye nokulahla umthwalo kwinkqubo yamandla, kuya kubangela ukunyuka kwevolthi yamandla okanye kuvelise i-transient overvoltage ene-amplitude ephezulu. I-arrester inokumelana ne-frequency yamandla athile kwixesha elithile. I-voltage yonyusa amandla.
