CDADAinyanzvi inogadzira Motor Protection Circuit Breakers, ichizvikudza 52,400 m² nzvimbo yekugadzira uye yakazara mitsara yekugadzira. Nemakore makumi maviri echiitiko mukugadzira uye kutengesa kwezvigadzirwa izvi, tinopa mhinduro dzepamusoro uye dzakasimba dzinogona kugadzirwa kuti isangane nezvinodiwa zvekushanda.

Chii chinonzi Motor Protection Circuit Breaker?

A Motokari Dziviriro Circuit Breaker (MPCB), anozivikanwawo seamotor circuit breaker kanamanual motor starter, inyanzvielectromechanical kudzivirira mudziyoyakagadzirirwa chaizvo kuchengetedza mota dzemagetsi kubva pakukanganisa kushanda. Kusiyana neruzhinji-chinangwa MCCBs, maMPCBs anobatanidzakuchengetedzwa kwekuremerwa, kuchengetedzwa kwepfupi-sekiti, uye nemaoko switching mune imwechete compact unit, yakagadziridzwa kune yakasarudzika zvinodiwa zvemotor kutanga uye kumhanya mamiriro.

Kushanda underIEC 60947-4-1 (contactors uye motor-starters) uyeIEC 60947-2 (circuit-breakers), MPCBs inobata zviyero zvazvino kubva0.63A kusvika 100A (kuwedzera ku150A mumhando dzakasiyana), ine zvinogadziriswa zvigadziriso zvekupisa kuti zvienderane nemota chaiyo yakazara-mutoro wazvino. Izvo zvakagadzirirwa kutsungirira motainrush currents (kazhinji 6-8 × yakazara-mutoro ikozvino panguva yekutanga) pasina kunetseka kukwira, uku ichipa kuchengetedzwa kwakaringana kubva pakuremerwa uye kutadza kwechikamu.

Iyo inotsanangura mukana weMPCBs iri mune yavomotor-optimized rwendo maitiro-zvinhu zvinopisa zvakarongerwa mota yekudziya macurves uye magineti nzendo dzakaiswa zvakanaka pamusoro pekutanga ikozvino asi pazasi ekukuvadza kukanganisa. Izvi zvinobvisa kudiwa kweakasiyana macontactor uye anoremedza relays mune akawanda maapplication, kuderedza mapaneru nzvimbo uye yekuisa yakaoma.
