I-GN30-12 I-Rotary high voltage yasendlini ehlukanisa i-swithc iwuhlobo olusha lweswishi ehlukanisayo enommese wokuxhumana ojikelezayo, ukwakheka kwayo okuyinhloko ukubeka amasethi amabili ezivikeli nokuxhumana ezindizeni ezingenhla nezingaphansi ze-chassis evamile yezigaba ezintathu kanye nokuqaphela ukuvula nokuvala iswishi ngokuzungezisa ummese wokuxhumana.
I-Gn30-12D yasendlini ye-rotary high voltage isolating switch isekelwe ku-GN30-12 ejikelezayo yasendlini ephezulu yokuhlukanisa i-swithc engahlangabezana nezidingo zezinhlelo zamandla ahlukene, lo mkhiqizo unomklamo ohlangene nendawo encane okuhlala kuyo.ikhono eliqinile lokuhlanganisa nokufaka nokulungisa kalula, ukusebenza kwayo kuhlangabezana nezidingo zamaswishi ahlukanisa ugesi aphezulu we-GB1985-89 AC kanye namaswishi aphansi, ilungele amasistimu angaphakathi anama-voltage akalwe angaphansi kuka-10kv AC50 Hz futhi ingasetshenziselwa ukuvula nokuvala amasekhethi ngaphansi. isimo se-voltage futhi akukho mthwalo engasetshenziswa ngegiya lokushintsha lamandla kagesi aphezulu noma isetshenziswe yodwa.
