Kohikohiko hiko 14550884 mo Volvo excavator

Whakatikahia nga tohu mahi matua

Ko te tohu mahi o te inductance coil te nuinga o te rahi o te inductance.I tua atu, i te nuinga o te korero, ko te waea i werohia me te coil inductance i nga wa katoa he tino parenga, he iti rawa te tikanga ka taea te warewarehia.Heoi, ka tino nui te ia e rere ana i roto i etahi iahiko, kare e taea te warewarehia tenei parenga iti o te porowhita, na te mea ka pau te mana o te hiko i runga i te porowhita, na te mea ka wera te kowiri, ka wera ranei, na i etahi wa ka pau te hiko. Ko te kaha e taea e te kowiri te tu atu me whakaaro.

Te whakaahuru

Ko te inductance l e tohu ana i nga ahuatanga o te porowhita ake, ahakoa te ahua o naianei.Hāunga te pōkai inductance motuhake (inductance tohu-tae), ko te inductance i te nuinga o te wa kaore i tino tohuhia ki runga i te porowhita, engari ka tohua ki te ingoa motuhake.Ko te Inductance, e mohiotia ana ko te whakarea-whaiaro, he rahinga tinana e tohu ana i te kaha o te whakaurunga whaiaro o te inductor.Ko te inductance o te inductor te nuinga ka whakawhirinaki ki te maha o nga hurihanga o te coil, te aratau awhiowhio, te aroaro, te kore ranei o te matua me te rauemi o te matua, me era atu. nui ake te inductance.Ko te inductance o te coil me te matua autō he nui ake i tera o te coil kaore he matua autō;Ko te nui ake o te uruhanga aukume o te matua, ka nui ake te inductance.

Ko te waeine taketake o te inductance ko Henry (Hen mo te poto), e tohuhia ana e te reta "H".Ko nga waeine e whakamahia nuitia ana ko te milli-Heng (mH) me te micro-Heng (μH), ko te hononga i waenganui i a raatau ko:

1H=1000mH

1mH=1000μH

Te tauhohenga arataki

Ko te nui o te parenga o te porowhita inductance ki te naianei AC ka kiia ko te inductance XL, me te ohm hei waeine me te ω hei tohu.Ko tona hononga ki te inductance L me AC auau F ko XL=2πfL.

Tauwehe kounga

Ko te tauwehe kounga Q he rahinga tinana e tohu ana i te kounga porowhita, a ko te Q te tauwehenga o te inductance XL ki tona parenga rite, ara, Q = XL/R. mahi inductor i raro i tetahi ngaohiko AC auau.Ko te teitei o te uara Q o te inductor, te iti o te mate me te teitei o te kaha.Ko te uara q o te porowhita e pa ana ki te aukati DC o te kaikawe, te mate dielectric o te anga, te mate i puta mai i te whakangungu rakau, i te matua rino ranei, te awe o te paanga o te kiri auau teitei me etahi atu mea.Ko te uara q o te porowhita he tekau ki te rau.Ko te take o te kounga o te inductor e pa ana ki te aukati DC o te waea coil, te mate dielectric o te anga coil me te mate na te matua me te whakangungu rakau.
