Chishandiso uye maitiro eDC isolation switch

Iyo DC yekuparadzanisa switch chishandiso chekudzivirira iyo pfupi dunhu pakati peAC neDC yeDC yekuparadzanisa switch. Iyo yakabatana neinoparadzanisa transformer pakati pemagetsi ekuisa terminal yeAC mota magetsi emagetsi switch kabati uye matatu-chikamu AC simba rekuisa mutsara, uye kupinza kwetatu-chikamu AC magetsi. Mutsetse wakabatana neyekutanga mhepo yekuzviparadzanisa yega transformer, uye yechipiri mhepo yekuzviparadzanisa yega transformer yakabatana nemagetsi inlet kupera kweAC mota magetsi emagetsi switch kabati.

Iyo DC yekuzviparadzanisa switch inogadzirisa iyo yekudzora sisitimu yeDC yekuzviparadzanisa switch mune yekutanga art. Nekuda kwekukuvara kweiyo insulator pakati pegomba re AC mota uye deceleration meshini ine DC simba uye zvimwe zvikonzero, iyo insulator simba rekudzivirira rinodzikiswa, kana kana mota ye AC ichidonha, tsaona dzeAC neDC pfupi-circuit. . Inonyatso kuchengetedza kushanda kwakachengeteka kwemagetsi ekugadzirisa magetsi uye kudzivirira kurasikirwa kukuru kwehupfumi uye kukuvara kwemunhu.

Chikamu chekushandisa

Iyo DC yekuzviparadzanisa switch inokodzera kuchengetedzwa kwega mumitsara ine ma voltages anoshanda anosvika 1000VDC uye yakayerwa mafungu kusvika ku100A, uye inoona kugoverwa kwemutoro.

kubviswa uye kuzviparadzanisa nevamwe kunobudirira. Inonyanya kushandiswa mumunda we photovoltaic.

Iyo DC isolation switch inonyanya kukodzera kuiswa kwemukati neAC 50/60Hz, yakayerwa voltage ye1500V, yakanyanya voltage ye1000V, uye yakayerwa ikozvino ye200A uye 400A. Pamusoro pekushandiswa kushandura magetsi emagetsi, DC inoparadzanisa switch inogona zvakare kushandiswa kugadzira nekupwanya maseketi.

Mamiriro ezvinhu

ADELS L2 akatevedzana DC bvisa switch

Chinonyanya kukosha ndechekuti kushandiswa kwakabudirira kweiyi tekinoroji kunoita kuti nyika yedu ive nehunyanzvi hwekutonhodza hwemahydro-jenareta makuru pasina kodzero dzepfuma. Mukutanga kwezana ramakore rechi21 munyika yangu, kuchave nenhamba hombe uye yakakura kwazvo ma hydro-generator akamirira kuvandudzwa uye kugadzirwa, uye kutonhora ndeimwe yeakakosha matekinoroji. Mabhenefiti akatanhamara ekugadzirisa zvakakwana, saka zvinotarisirwa zvehupfumi nemagariro zvichave zvakakura.

Iyo DC disconnect switch inouya kubva mukubatanidza kwemagetsi muchina, mota chimiro, engineering thermophysics uye dielectric electrochemistry, uye ine zvakapfuma zvemukati. Nekudaro, chimiro chinodiwa kuti uzvizive pamota hachina kuoma, saka mashandisirwo eiyi tekinoroji yakawedzera. Kazhinji kutaura, iyo hydro-jenareta ine simba rinopfuura 200 megawatts inogona kuwana zvakanaka zvehupfumi nekushandisa tekinoroji iyi. Kune mayunitsi anotanga kazhinji (senge pombi-yekuchengetera magetsi emagetsi) kana anoda super-inogadzira huwandu (kusanganisira kuwedzera simba), pachave nemhedzisiro iri nani.
