ZN73-12 series indoor three-phase AC high-voltage vacuum circuit breaker yakagadzirwa nePeople Electric chishandiso chekudzivirira core switching chakagadzirirwa masisitimu emagetsi eAC e12kV, 50Hz matatu-phase. Yakagadzirirwa maindasitiri nemaindasitiri emigodhi, mafekitori emagetsi, zviteshi zvemagetsi nezvimwe zviitiko, inoshanda semudziyo unokosha mumasisitimu emagetsi eindasitiri, ine zvakanakira zvikuru uye kugona kuchinjika zvinoratidzwa muzvikamu zvina:
1.Kugadziriswa Kwemamiriro Ezvinhu Akarurama & Kuisa Nzvimbo Yepakati: Inogonesa kuchinja mitoro yakasiyana-siyana uye kudzivirira & kudzora nzvimbo dzemagetsi, kunyanya dzakakodzera mamiriro emagetsi emaindasitiri anodakuvhiyiwa kakawanda, ichipa mhinduro dzekudzivirira simba zvakananga uye dzekudzora mamiriro ekupararira kwemagetsi ane simba repamusoro-soro ezviyero zvakasiyana.
2.Kushanda Kwakanaka Kwekudzimisa Arc & Dhizaini Yechivakwa: Ichishandisa vacuum senzira yekubatanidza magetsi nemidziyo yekudzivirira magetsi, ine simba shoma remagetsi, simba remagetsi rakawanda uye simba rekudzivirira magetsi mushure mearc kuti ibvise magetsi nekukurumidza uye zvakadzikama. Inoshandisa dhizaini yakabatana ine mashandiro ekushanda nekamuri rekudzimisa magetsi rakarongwa pamberi nepashure, uye dunhu guru remhando nhatu repasi. Kamuri rekudzimisa magetsi rakaiswa mu cylinder cast ine epoxy resin kuburikidza netekinoroji yeAPG, ichipa simba rekudzivirira magetsi neguruva shoma. Panguva iyi, inoderedza ma "intermediate transmission link" kuti ideredze kushandiswa kwesimba uye ruzha nekushanda kwakavimbika.
3.Kugadziriswa Kwechimiro Chinochinjika & Dziviriro Yakazara: Inowanikwa mumhando yakagadzikauyerudzi rwekudhonza, inogona kuiswa mumakabati eswitch akagadziriswa uye anogona kubviswa zvichiteerana kuti isangane nezvinodiwa zvakasiyana-siyana zvekuisa nekushanda nekugadzirisa. Yakashongedzerwa nezvinhu zvakakwana zvekudzivirira magetsi zvinosanganisira anti-trip relay, over-current tripping electromagnet uye energy storage micro-switch, inovandudza zvikuru kuchengetedzeka kwekushanda kwayo. Inoshanda zvakanaka pa -10℃ kusvika +40℃, inotsungirira kudengenyeka kwenyika kusvika pahukuru hwe8, uye inoshanda zvakavimbika munzvimbo dzisina magasi anoparadza/anobvira moto kana kudedera kwakanyanya. Masevhisi akagadzirirwa anopiwa kune mamiriro ekushanda akakosha.
4.Kusarudzwa Kwemhando Dzakasiyana-siyana & Mutengo Wakaderera Wekushanda & Kugadzirisa: Magetsi ane mwero anotangira pa630A kusvika 3150A, uye magetsi ane mwero wepfupi anofukidza 20kA kusvika 40kA, zvichibvumira kusarudzwa kunochinjika zvichienderana nemagetsi chaiwo ari panzvimbo. Nehupenyu hwebasa remakanika hurefu, kugadzirisa kuri nyore, kusasvibiswa uye pasina njodzi yekuputika, zvinoderedza zvinobudirira mari yekushanda nekugadzirisa kune vashandisi vemaindasitiri.
Zvikuru zveChigadzirwa
1.Hunhu hweChigadzirwa: Muchina wekudzima magetsi une ma "vacuum circuit breaker" wemukati une ma "phase three-phase AC" wakagadzirirwa masisitimu emagetsi e12kV/50Hz, uchienderana nezvinodiwa nenyika. Muchina wekudzima magetsi une ma "vacuum arc" unoita kuti pave nekushanda kwakanaka kwe "arc extinguishing" uye "insulation performance".
2.Zvakanakira Zvikuru: Kubatana kwemhangura nechromium kusingashande zvakanaka uye kwenguva refu; chimiro chakabatana chine simba shoma rinoshandiswa, kuramba kutsvedza uye kuramba kusvibiswa; hupenyu hwebasa remakanika hunosvika zviuru gumi, kuvhura/kuvhara nekukurumidzamhinduro uye kugona kukuru kwekupwanya zvikanganiso; zvikamu zvakakwana zvekudzivirira kuti basa rive rakachengeteka.
3.Maitiro Ekushandisa: Kudzivirirwa nekudzora nzvimbo dzemagetsi mumabhizinesi emaindasitiri nedzemigodhi, mafekitori emagetsi, zviteshi zvemagetsi,inonyanya kukodzera kushandura mutoro nekushanda kakawanda.
4.Maumbirwo & Kugadzirisa: Zvivakwa zvakagadziriswa uye zvinodhonzwa zvinogona kushandiswa kumakabati akasiyana-siyana ekuchinja; kugadzirwa kwakagadzirirwa kunowanikwa kune mamiriro ekushanda akakosha uye kuchinjika kwakasimba kwezvakatipoteredza.
