Chinangwa chikuru che-high-voltage isolate switch

1. Inoshandiswa kuparadzanisa magetsi kuti ave nechokwadi chekuchengetedzwa kwekuchengetedza, kuitira kuti zvigadzirwa zvemagetsi zviri pasi pekugadzirisa zvine nzvimbo yakajeka yekubvisa kubva kune magetsi;

2. Ita kushandura-kudzima kushanda kuti uchinje maitiro ekushanda kwegadziriro. Semuenzaniso, munharaunda ine kaviri busbar kushanda, shandisa shanduko yekuzviparadzanisa kushandura michina kana mutsara kubva kune rimwe boka remabhasi kune rimwe boka remabhasi;

3. Pasi pemamwe mamiriro ezvinhu, inogona kushandiswa kubatanidza uye kugura maduku maduku emazuva ano. Kana uchishandisa switch yekuzviparadzanisa nevamwe, zvinotevera mashandiro anogona kuitwa:

1) Gurai uye vharai voltage transformer uye maseketi ekusunga.

2) Gurai uye uvhare iyo yekuchaja ikozvino yebhazi.

3) Mapoinzi, hapana-mutoro transformers ayo akasanganiswa excitation ikozvino haipfuure 2A uye hapana-mutoro mitsetse iyo capacitive ikozvino isingapfuure 5A.

Tiye classification ye high voltage isolation switch

1. Maererano nenzvimbo yekuisa, yakakamurwa kuva marudzi maviri: mukati uye kunze;

2. Maererano nenhamba yematanda, yakakamurwa kuva marudzi maviri: unipolar uye tripolar;

3. Maererano nehuwandu hwembiru dzekudzivirira, yakakamurwa kuva marudzi matatu: imwe-column type, double-column type uye nhatu-column type;

4. Maererano nemaitiro ekugadzirisa, yakakamurwa kuva marudzi matatu: guillotine type, screw type uye plug-in type;

5. Maererano nemabasa akasiyana-siyana, yakakamurwa kuva marudzi maviri: nekugadzirisa banga rekugadzirisa uye pasina kushandura banga;

6. Maererano nemaitiro ekushanda anoshandiswa, inoparadzaniswa kuva: manual, magetsi uye pneumatic maitiro ekushanda.

Abnormal phenomenon uye kurapwa kweyakakwira voltage isolating switch

1. Chikamu chekubatanidza chekushandura kwekuparadzanisa chinopisa

Mumamiriro ezvinhu akajairwa, switch yekuzviparadzanisa haifanirwe kuve yakawandisa. Kana iyo yekuzviparadzanisa switch ikawanikwa ichipisa panguva yekushanda, matanho anotevera anofanira kutorwa:

1) Muchikamu chechipiri chebhasi, kana rimwe boka remabhasi rinopisa rinopisa, rinofanira kuchinjwa kune rimwe boka remabhasi; apo imwe chete busbar system disconnector inopisa, edza kuderedza mutoro. Kana mamiriro ezvinhu achibvumira, zviri nani kutora switch yekuzviparadzanisa kunze kwekushanda. Kana simba rinogona kugurwa, rinofanira kugadziriswa pakarepo, kana zvisina kudaro, kutarisa kunofanira kusimbiswa. Kana kupisa kwakanyanya, iyo inopindirana inoputika inofanira kubviswa maererano nemitemo.

2) Kana iyo yekubatanidza chikamu chemutsara wekutsaura switch ichipisa, nzira yekurapa yakafanana neyeiyo imwe bhazi yekuparadzanisa switch, asi nekuda kwekuchengetedzwa kwemugero wedunhu munhevedzano, switch yekuzviparadzanisa inogona kuramba ichishanda, asi yekutarisa inoda kusimbiswa kusvika kupera kwemagetsi kuchigona kugadziriswa.

2. Kukanganisa-kudhonza uye kusavhara-kuvhara yekuzviparadzanisa switch nemutoro

Iyo yekuparadzanisa switch haina arc yekudzima simba, uye inorambidzwa zvachose kudhonza kana kuvhara switch yekuzviparadzanisa nemutoro. Kana chiitiko ichi chikaitika, chinofanira kutariswa sezvinotevera:

1) Dhonza switch yekuzviparadzanisa nekukanganisa

Kana iyo blade ichangobva kumucheto weblade (iyo arc yakarohwa asi isina kuputsika), iyo disconnector isati yavhurwa inofanira kuvharwa pakarepo kudzivisa arc short-circuit; kana iyo disconnector yakavhurwa, haibvumirwi kuvhara, uye iyo disconnector inofanira kuvimbiswa Vhura nzvimbo, bvisa dhipatimendi nemutambo wedunhu, uye wobva wavhara shanduko yekuzviparadzanisa.

2) Kutadza-kuvhara iyo yekuparadzanisa switch

Mushure mokunge disconnector yakavharwa zvisizvo nemutoro, haibvumirwi kuvhurwa zvakare, uye inofanira kuvhurwa mushure mokunge muparadzi wedunhu abvisa dunhu.

3. Shanduko yekuzviparadzanisa inoramba kuvhura nekuvhara

1) kuramba kuvhara

Kana iyo yekuzviparadzanisa switch ichiramba kuvhara nekuda kwekutadza kwemuchina, inogona kushandiswa netsvimbo inodzivirira, kana mune yekuvimbisa kuchengetedzwa kwemunhu, shandisa wrench kushandura shaft inotenderera yekuzviparadzanisa nevamwe.

2) kuramba kuvhura

Kana iyo yekuzviparadzanisa switch isingagone kuvhurwa, kana iyo inoshanda yakaomeswa nechando, unogona kuizunza zvinyoro nyoro kuti uwane chipingamupinyi. Kana chipingamupinyi chiri muchikamu chekubatanidza chekuchinja, hachigone kuvhurwa nechisimba, kana zvisina kudaro bhodhoro rinotsigira porcelain rinogona kukuvara.

4. The isolation switch porcelain yakakuvadzwa

Kana iri flashover discharge, kutarisa kunofanira kusimbiswa, uye kucheneswa kunofanira kuitwa mushure mokukumbira kubuda kwemagetsi; kana bhodhoro reporcelain rinotsigira rakakuvadzwa uye rakatyoka, muparadzi wedunhu anofanirwa kushandiswa kubvisa dunhu, uye switch yakakuvadzwa yekuzviparadzanisa inofanira kubviswa kuti igadziriswe.
