Plastic shell circuit breaker (plastic shell air insulated circuit breaker) inoshandiswa zvakanyanya muindasitiri yakaderera-voltage yekuparadzira, inoshandiswa kucheka kana kupatsanura iyo yakajairwa uye yakayerwa 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 kunyatsosiyanisa iyo huru yekusangana nyika, uye yekuteedzera yedunhu inotyora inofanirwa kuiswa ne "AJ" chiratidzo. yakabudiswa nedhipatimendi rakakodzera rekuchengetedza.
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 kupfupi redunhu kukundikana kana redunhu ikozvino kwenguva refu kupfuura rated. ikozvino yedunhu rinopaza rwendo, saka inozivikanwa zvakare sekufamba kaviri, inowanzoshandiswa mune zvakajairika magetsi ekugovera zviitiko.Electroniki tripping tekinoroji yakakura iri kubuda mumakore achangopfuura, ine electronic tripping circuit breaker magnetic tripping current, hot tripping current, uye nguva yekugumburwa inogadziriswa, nguva dzinoshandiswa zvakanyanya, asi mutengo wemutengi wedunhu wakakwira.Pamusoro pemhando nhatu dziri pamusoro pezvishandiso zvekutsika, uyezve, pane chinotyora chedunhu chinoshandiswa zvakanyanya pakudzivirira dunhu.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 yekubata, 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.
