Iwe unonzwisisa chaizvo shanduko yekuchinja?–AISO

Chii chinonzi anisolate switch

 Iyo yekuparadzanisa switch,Iyo inozivikanwawo sekuti banga switch, imhando yepamusoro-voltage switch.Iyo haina arc yekudzima mudziyo.Kana iri munzvimbo yakavharwa, inogona kutakura kushanda ikozvino, asi haigoni kushandiswa kubatanidza kana kutema mutoro wezvino uye pfupi-circuit current.Inofanirwa kushandira pamwe neyedunhu breaker.

2. Chinangwa cheisolate switch

 2.1 Isolation voltage: Panguva yekugadzirisa, midziyo yemagetsi inoparadzaniswa kubva kune inomhanya gidhi remagetsi ine yekuparadzanisa switch kuti igadzire iri pachena gap rekubvisa, kuitira kuve nechokwadi chekuchengetedzwa kwekushanda nekugadzirisa.

2.2 Kudzima mashandiro: chinja bhazi rekuchengetedza kana bhazi rekupfuura uye shandura maitiro ekushanda, shandisa switch yekuzviparadzanisa uye wedunhu rinotyora kuti upedze.

 Mune yakapetwa kaviri bhasi yekubatanidza modhi, chinhu chekubatanidza chinochinjirwa pakati pemabhazi maviri nekushandisa pa-kudzima kweiyo yekuparadzanisa switch chinzvimbo pamabhazi maviri.

 2.3 Kubatidza nekudzima diki yazvino dunhu: Iyo yekuparadzanisa switch ine kumwe kugona kuvhura nekudzima diki inductive ikozvino uye capacitive ikozvino.Iyo yekuparadzanisa switch inogona kushandiswa kune anotevera mashandiro panguva yekushanda:

 ①.Inogona kushandiswa kubatanidza uye kubvisa magetsi emagetsi uye zvinosunga.

 ②.Batanidza uye bvisa mitsara yekutumira isina-kutakura ine capacitance ikozvino isingadariki 5A, voltage ye10kV, uye tambo yekutumira isina-mutoro ine kureba isingasviki 5km uye isina-mutoro tambo yekufambisa ine voltage ye35kV uye kureba. isingasviki 10km.

 ③.Batidza uye udzime iyo isina-mutoro transformer iyo yekunakidza ikozvino isingapfuuri 2A: iyo 35kV kirasi iri pasi pe1000kVA, uye kirasi ye110kV iri pasi pe3200kVA.

 2.4 Otomatiki uye nekukurumidza kuzviparadzanisa: Pasi pemamwe mamiriro, inogona kukurumidza kutsaura michina uye mitsetse yakatadza kuzadzisa chinangwa chekuchengetedza huwandu hwemadunhu.

Kana uine chero mubvunzos kana chero chigadzirwa chinoda, ndapota inzwa wakasununguka kundibata.
