Zviteshi zvemakeji echitubu zvemaindasitiri zvinokwana 0.08-16mm² (inenge 28 AWG kusvika 6 AWG). Mhando dzemagetsi akasimba dzinosvika 35mm² kana 50mm² pakushandiswa kwemagetsi. Rudzi chairwo runosiyana zvichienderana nemugadziri uye zvigadzirwa, saka tarisa nehurongwa hwewaya yako. Kune maconductor makuru kwazvo anopfuura 50mm², mabhuroko emagetsi kana mabhaudhi anobatanidza anowanzo kukodzera kupfuura magadzirirwo emakeji echitubu.

Ko materminal e spring cage anoshanda here nema bootlace ferrules?

Ehe. Maferule eBootlace—asina kuputirwa kana kuti asina kuputirwa anovhara maconductor anovhara stranded—anonyatsoenderana nematerminals mazhinji e spring cage. Upamhi hweferule huri mukati menguva yakajairika yekushanda kwe spring, uye magumo akaputirwa anopa nzvimbo yakachena yakaita se cylindrical iyo spring inobata zvakaenzana. Kushandisa maferrules kunokurudzirwa kune waya gauges dziri pasi pe2.5mm² munzvimbo dzinodedera kudzivirira kutyoka kwetambo uye kuona kuti tambo yacho inogara yakabatana zvakanaka.

Zviteshi zvemakeji echitubu hazvipindi kudedera here?

Hapana kubatana kwemagetsi "kunodzivirira kudedera" mupfungwa chaiyo. Zviteshi zvemakeji echitubu ndizvo inodzivirira kudedera kune mwero wakatsanangurwa wekuomarara, unowanzo bvumidzwa pasi peIEC 60068-2-6 pa5g, 5-150Hz. Kupfuura kuomarara ikoko, matanho ekuwedzera—akadai semakonzo emuhari, kusunungura kusvuta kwetambo, kana kuti zvigadziko zvekuparadzanisa vibration—zvinogona kudiwa. Tsanangudzo chaiyo haisi "inodzivirira kudedera" asi "yakaedzwa kukudedera kusvika paX kwekuomarara kwenguva yeY."

Ndingaite sei kuti ndione kuti nzvimbo yekuchengetera zvinhu zvechitubu ndeyechokwadi kwete yekunyepera?

Zvivharo zvemagetsi zvenhema zviri kuramba zvichikura, kunyanya mumisika ine mitemo isina kutenderwa yekupinza zvinhu. Zvigadzirwa zvechokwadi zvine zviratidzo zvemugadziri, nhamba dzenzvimbo dzinotevedzwa, uye zvitupa zvekuyedza zvevamwe (UL, VDE, TÜV). Kumbira zvitupa zvakananga kubva kumutengesi ane mvumo wemugadziri, kwete kubva kumutengesiKana mutengo uri pasi pe40% pamusika, chigadzirwa chacho chingangove chiri chenhema. Mutengo wechiteshi chakakundikana mumutsara wekugadzira uri kushanda unodarika chero mari inochengetwa kubva pakutenga zvakachipa.

Mareferensi eChigadzirwa

Kuti uwane mabhuroko ekupedzisira emakeji echitubu akagadzirirwa nzvimbo dzemaindasitiri dzinodedera zvakanyanya, ona peji rino. katarogu yakazara yezvigadzirwa. Rudzi urwu runosanganisira materminal eDIN-mounted spring cage terminals ari padanho remagetsi kubva pa2.5A kusvika 125A, nekugamuchirwa kwewaya kubva pa0.08mm² kusvika 16mm², kusanganisira maconductors ane stranded uye ferruled.

Kuti muenzanise terminal ye push-in uye mashandisirwo ayo akakodzera kushandisa waya dze conductor dzakasimba, onai PCT-211 DIN njanji inosundidzira waya muchikamu chemagetsi.
