Kuti udzivise dambudziko rekushongedza, mukuwedzera kune iyo yekuvhurwa kwekubhadharisa murwi, kusarudzwa kwekudziviridzira kwetsiva kwakakoshawo. Maererano neNational Standard Gb / T 187487.1, Iyo Dziviriro yekushambadzira yekuchaira inofanirwa kushandisa Type B kana Nyora A, iyo isingadziviriri kubva kuac llage, asi zvakare inodzivirira nekupokana neDupsating DC. Musiyano mukuru pakati peType B uye Type A ndirwo rudzi rweB yakawedzera kudzivirirwa neDC Lakwa. Nekudaro, nekuda kwekunetseka uye kurasikirwa nemhando yeBLT B kuona Zvinogona kutaurwa kuti chirwere chiripo chekudzivirirwa kwekubhadhara marunda akavanzwa njodzi pachiyero chakajairwa.
Nyora leakage wedunhu breaker
Iyo-Type Laaka Dunhu Rinotambidza uye AC-Type Leakage Circed Breaker Iyo inovimbisa kurira pasi pemamiriro ezvinhu anotevera:
(a) zvakafanana ne ac mhando.
(b) yakasara yekudhonzwa DC ikozvino.
.
Type B LEAKAGE CIRDUIT Breaker - (Chinaevse inogona kuita RCD Type B)
Type B circut circut circakes dzinogona kuvimbika dzinochengetedza sinusoidal ac signals, pulsing Iyo inovimbisa kurira pasi pemamiriro ezvinhu anotevera:
a) zvakafanana nerudzi A.
b) yakasara sinusoidal kuchinjanisa izvozvi kusvika ku1000 HZ.
c) Iyo yakasara AC iripo inotaridzika neiyo yakasarudzika dc iripo ye1.4 times iyo yakatemwa yakasara iripo
d) iyo yakasara yekudhonzwa DC ikozvino inotsemurwa ne 0,4 nguva iyo yakatsemurwa yakasara yazvino kana yakatsetseka dc ikozvino ye 10ma (chero yakakura).
e) Nguva dzakasarudzika Dc dzinogadzirwa nematunhu anotevera ekunyorwa:
- Chikwama zviviri-wave bridge inobatanidza mutsara kune mutsara wechipiri-, 3- uye 4-pole Pasi Pasi Pasi Pasi Pasi Pasi Dunhu.
- YEMAHARA 3-POLLE uye 4-pole Pasi Lakage Circuit Circemers, 3 hafu-wave nyeredzi kubatana kana 6 hafu-wave bridge contions.
