Plastic shell circuit breaker (plastic shell air insulated circuit breaker) inoshandiswa zvakanyanya muindasitiri yakaderera-voltage yekuparadzira, inoshandiswa kucheka kana kupatsanura iyo yakajairwa uye yakatemerwa huwandu hwekukanganisa ikozvino, kuve nechokwadi chekuchengetedzwa kwemitsara nemidziyo. zvinoenderana nezvinodiwa neChina "Temporary Power Safety Technical Specification", iyo yenguva pfupi simba redunhu redunhu panzvimbo yekuvaka inofanirwa kuve yakajeka goko, inogona kusiyanisa zvakanyanya iyo huru yekusangana nyika, uye yekuteerera dunhu. breaker inofanirwa kuve yakanamirwa neiyo "AJ" mucherechedzo wakapihwa nedhipatimendi rekuchengetedza rakakodzera.
QF inowanzo shandiswa kumiririra inotyora dunhu, uye madhirowa ekunze anowanzo kunzi MCCB.Common plastic shell circuit breaker tripping nzira dziri single magnetic tripping, inopisa magineti inofamba (double tripping), electronic tripping.Single magnetic tripping zvinoreva kuti dunhu. breaker chete nzendo kana dunhu ane pfupi redunhu kukundikana, uye isu tinowanzo shandisa chinja ichi ari hita loop kana motokari redunhu pamwe overload kudzivirira basa.Thermal magineti tripping ari mutsetse pfupi redunhu kukundikana. kana dunhu razvino kwenguva yakareba rinopfuura iro rakatemerwa ikozvino redunhu rinotyora rwendo, saka rinozivikanwawo sekufamba kaviri, rinowanzoshandiswa mune zvakajairika magetsi kugovera zviitiko. breaker magnetic tripping current, inopisa kukwenya ikozvino, uye nguva yekugumburwa zvinochinjika, zvakanyanya kushanda nguva zhinji, asi mutengo wecircuit breaker wakakwira.Pamusoro pemhando nhatu dziri pamusoro dzezvishandiso zvekutsika, uyezve, kune dunhu. breaker inonyanya kushandiswa kuchengetedza mota yedunhu. Yayo magineti inofamba ikozvino inowanzo pamusoro pegumi nguva yakayerwa ikozvino kudzivirira iyo yepamusoro ikozvino kana mota yatanga uye nekuona kuti mota inotanga mushe uye inotyora yedunhu haifambi.
Plastic shell circuit breaker ine zvakasiyana-siyana zvekushandisa zvinogona kusungirirwa, senge kure emagetsi oparesheni switch mechanic, excitation coil, yekubatsira kubata, alarm kubata, nezvimwe.
Paunenge uchisarudza iyo yemagetsi mashandiro emagetsi, kutarisisa kunofanirwa kubhadharwa kune inotsigira yedunhu breaker imba furemu ikozvino, nekuti hukuru hwekunze hweakasiyana ganda furemu yazvino wedunhu breaker uye torque yekuvhara masisitimu akasiyana.
