Musiyano mukuru ndewekuti chivharo chezvivharo chinosanganisira madziro akasimudzwa ekudzivirira pakati penzvimbo yega yega yemagetsi kune zvinobatanidzwa zviri pedyo zvakasiyana, nepo chivharo chezvivharo chinowanzova nemigero yakapfava kana yakavharika isina zvivharo zvinoparadzanisa. Zvivharo zvinopa dziviriro yepamusoro kubva kumakona emagetsi uye mapfupi, zvichiita kuti zvive sarudzo inosarudzwa yekugovera simba remagetsi ane simba rakawanda kupfuura 250 V. Zvivharo zvezvivharo zvidiki uye zvinodhura zvishoma kune waya dzemagetsi uye madunhu ekudzora ane simba rakaderera. Mukugadzira mapaneru, tinowanzo shandisa zvivharo zvezvivharo zveAC mains nemotor circuits uku tichishandisa zvivharo zvezvivharo zvePLC ne sensor connections.
Ndezvipi saizi dzemuchina wekufambisa zvinhu zvinogona kugarwa nemabhatiri emagetsi?
Zvivharo zvezvivharo zvinokwana saizi dzakasiyana-siyana dzemakonductor zvichienderana nerudzi rwemakonductor. Zvivharo zvakajairika zvinotangira pa0.2 mm² (AWG 24) yekubatanidza waya kusvika pa300 mm² (600 kcmil) yekuparadzira simba guru. Zvivharo zvezvivharo zvinozivikanwa zvikuru zvinobata 2.5 mm² kusvika 16 mm² (AWG 14 kusvika AWG 6). Modhi yega yega yezvivharo inotsanangura chikamu chidiki uye chepamusoro chekonductor pamwe chete ne torque inosimbiswa yekusimbisa ma screw terminals. Kupfuura waya yakayerwa kunokanganisa kuramba kwekubatana uye kuvimbika kwenguva refu.
Ndingaongorora sei mhando yemugadziri wezvivharo zvemagetsi zvinodzivirira magumo?
Kuti uone hunhu hwemugadziri wezvivharo zvezvivharo zvemagetsi, kumbira mishumo yebvunzo yevamwe vanhu kuti vaone simba re dielectric (kazhinji 2500 V AC kweminiti imwe pa UL 1059), kukwira kwekupisa pamagetsi akayerwa, uye kutsungirira kwemuchina (nhamba yematanho ekuisa/kubvisa). Kumbira zvitupa zvemidziyo — UL 94 V-0 yakayerwa PA66 kana PBT zvinhu zvekugara zvinoratidza kuti moto hauchashandi zvakanaka. Shanyira fekitori kana kukumbira vhidhiyo yekushanyira kuti uongorore kunyatsoita kwemuumbi uye hunhu hwemuumbi. Tarisa mienzaniso yehukobvu hwemadziro akayerwa, nzvimbo dzisina burr, uye kubatana kwakasimba kweshinda dze screw. Mugadziri ane mukurumbira anofanira kupa zvese izvi pasina kuzeza.
Unoda mugadziri wezvivharo zvemagetsi zvekudzivirira waunogona kuvimba naye here?
Bata Yvonne kuJ-GUANG kuti uwane madhatabheti ehunyanzvi, masampuli emahara, uye mutengo wepurojekiti yako inotevera yekugovera magetsi.
