Chii chinonzi pasi pevhu chinoputika-chinodzivirira kupatsanura switch?zvinoguma nei?

Disconnector (disconnector) zvinoreva kuti kana iri mu sub-position, pane insulation distance uye chiratidzo chedimburwa chiri pachena pakati pematanho anozadzisa zvinodiwa;kana iri munzvimbo yakavharwa, inogona kutakura ikozvino pasi pemamiriro edunhu akajairika uye mamiriro asina kujairika mukati menguva yakatarwa (senge pfupi-dunhu) ikozvino switching kifaa.
Iyo yekuparadzanisa switch yatiri kutaura nezvayo kazhinji inoreva kune yakakwira-voltage yekuparadzanisa switch, kureva, yekuparadzanisa switch ine yakatemerwa voltage ye1kv uye pamusoro, inowanzonzi switch yekuzviparadzanisa nevamwe, inova ndiyo inonyanya kushandiswa mudziyo wemagetsi mune yakakwira-. voltage switching midziyo.Uye chimiro chacho chiri nyore, asi nekuda kwehuwandu hwekushandisa uye zvakanyanya zvinodiwa zvekuvimbika kwebasa, zvine simba guru pakugadzira, kugadzwa uye kushanda kwakachengeteka kwezviteshi uye magetsi emagetsi.Chinhu chikuru chekuchinja kwebanga ndechekuti haina arc yekudzima kugona, uye inogona kungopatsanura nekuvhara dunhu pasina mutoro ikozvino.
Isolation switch inowanzoshandiswa mumigodhi yemarasha switch:
1) Mushure mekuvhura, gadza yakavimbika yekuvharisa gap, uye patsanura midziyo kana mitsara inoda kugadziriswa kubva kune magetsi neinongedzo yekumisa nzvimbo kuti ive nechokwadi chekuchengetedza kwevashandi vekuchengetedza uye michina.
2) Maererano nezvinodiwa zvekushanda, shandura mutsara.
3) Inogona kushandiswa kupatsanura uye kusanganisa madiki mafungu mumutsara, senge yekuchaja ikozvino yemabhushi, mabhazi, majoini, mapfupi tambo, iyo capacitive ikozvino yekuchinja balancing capacitors, ikozvino inotenderera kana kaviri mabhazi achinjirwa uye kunakidzwa. ikozvino voltage transformers Mira.
4) Zvinoenderana nemamiriro ezvinhu emhando dzakasiyana dzemagadzirirwo, inogona kushandiswa kupatsanura uye kusanganisa iyo isina-mutoro yekukurudzira ikozvino yeimwe simba rekushandura.
Zvinoenderana neakasiyana nzira dzekuisa, yakakwira-voltage yekuzviparadzanisa switch inogona kukamurwa kuita ekunze-yakakwirira-voltage yekuzviparadzanisa switch uye yemukati yakakwira-voltage yekuzviparadzanisa switch.Kunze kwakakwira-voltage yekuparadzanisa switch inoreva kune yakakwira-voltage yekuparadzanisa switch iyo inogona kumira nemhepo, mvura, chando, tsvina, condensation, ice uye gobvu chando, uye akakodzera kuisirwa pamateru.Inogona kukamurwa kuita imwe-column disconnector, kaviri-column disconnector uye matatu-column disconnector zvinoenderana nechimiro cheiyo insulating struts.Pakati pavo, imwe-column knife switch yakananga inoshandisa nzvimbo yakamira semagetsi ekudzivirira kwekuputsika pasi pebharu repamusoro.Nokudaro, ine mabhenefiti akajeka ekuchengetedza pasi nzvimbo, kuderedza tambo dzekutungamira, uye panguva imwechete, kuvhura nekuvhara nyika kunonyanya kujeka.Panyaya ye-ultra-high voltage power transmission, mhedzisiro yekuchengetedza nzvimbo yepasi inonyanya kukosha mushure mekunge imwe-column knife switch ichishandiswa mune substation.
Mumidziyo yakaderera-voltage, inonyanya kukodzera kune yakaderera-voltage terminal magetsi ekugovera masisitimu akadai sezvivakwa zvekugara uye zvivakwa.Mabasa makuru: nekutyora kwemutoro uye yekubatanidza mutsara
features
1. Kana midziyo yemagetsi ichiwedzerwa, nguva yemagetsi inopiwa, uye inzvimbo yakajeka yekuvhara kuti ave nechokwadi chekuchengetedzwa kwega kwevashandi vekuchengetedza.
2. Shanduko yekuzviparadzanisa haigone kushandiswa nemutoro: haigone kushanda neyakarongerwa mutoro kana mutoro wakakura, uye haigone kupatsanura uye kusanganisa mutoro ikozvino uye pfupi-yedunhu ikozvino, asi avo vane arc yekudzima kamuri vanogona kushanda nemutoro mudiki uye hapana-mutoro mutsara. .
3. In general power transmission operation: tanga wavhara chinja chekuzvitsaura, wobva wavhara chivharo chedunhu kana chinja chekutakura;kana switch yekuzviparadzanisa yakadzimwa: tanga wabvisa dhiraivha yedunhu kana chinja chekutakura, wobva wabvisa switch yekuzviparadzanisa.
4. Kusarudzwa hakuna kusiyana nemamwe midziyo yemagetsi, iyo yose inofanira kuenzaniswa nemagetsi, chiyero chemazuva ano, dynamic stable current, thermal stable current, etc. inofanira kusangana nezvinodiwa zvekushandiswa.
Basa rekuparadzanisa switch nderokubvisa dunhu rekuti hapana-mutoro wezvino, kuitira kuti midziyo igadziriswe uye magetsi emagetsi ave nenzvimbo yekubvisa iri pachena kuti ave nechokwadi chekuchengetedzwa kwevashandi vekuchengetedza.Iyo yekuparadzanisa switch haigone kudzima mutoro wazvino uye pfupi-yedunhu ikozvino pasina yakakosha arc yekudzima mudziyo., saka shanduko yekuzviparadzanisa inogona kungoshandiswa chete kana dunhu rakabviswa nedunhu rinoputika.
