Ikhoyili kagesi engu-14550884 ye-Volvo excavator

Hlela izinkomba zokusebenza eziyinhloko

Inkomba yokusebenza yekhoyili ye-inductance ikakhulukazi ubukhulu be-inductance. Ngaphezu kwalokho, ukukhuluma ngokujwayelekile, isilonda socingo ngekhoyili ye-inductance njalo sinokuphikiswa okuthile, okuvame ukuba kuncane kakhulu futhi kunganakwa. Kodwa-ke, lapho ukugeleza kwamanje kwezinye izifunda kukhulu kakhulu, lokhu kumelana okuncane kwekhoyili akukwazi ukushaywa indiva, ngoba umsinga omkhulu uzodla amandla kukhoyili, okwenza ikhoyili ishise noma iphele, ngakho ngezinye izikhathi ugesi. amandla ikhoyili engamelana nawo kufanele acatshangelwe.

I-inductance

I-inductance l imelela izici ezingokwemvelo zekhoyili ngokwayo, kungakhathaliseki ukuthi yamanje. Ngaphandle kwekhoyili ye-inductance ekhethekile (i-inductance enekhodi yombala), i-inductance ngokuvamile ayimakwa ngokukhethekile kukhoyili, kodwa imakwe ngegama elithile. I-inductance, eyaziwa nangokuthi i-self-inductance coefficient, inani elibonakalayo elibonisa ikhono lokuzingenisa le-inductor. I-inductance ye-inductor incike kakhulu enanini lokuphenduka kwekhoyili, imodi yokujika, ukuba khona noma ukungabikho kwe-core kanye ne-material ye-core, njll. Ngokuvamile, lapho amakhoyili aphenduka kakhulu futhi amakhoyili aminyene ayalimala, i-inductance enkulu. I-inductance yekhoyili enomgogodla kazibuthe inkulu kunaleyo yekhoyili engenawo umgogodla kazibuthe; Uma kukhulu amandla kazibuthe we-core, i-inductance inkulu.

Iyunithi eyisisekelo ye-inductance nguHenry (iHen ngamafuphi), emelwe uhlamvu "H". Amayunithi asetshenziswa kakhulu yi-milli-Heng (mH) kanye ne-micro-Heng (μH), futhi ubudlelwano phakathi kwawo yilokhu:

1H=1000mH

1mH=1000μH

Ukusabela kwe-inductive

Ubukhulu bokumelana kwekhoyili ye-inductance ku-AC yamanje kubizwa ngokuthi i-inductance XL, ne-ohm njengeyunithi kanye no-ω njengophawu. Ubudlelwano bayo ne-inductance L kanye ne-AC frequency F yi-XL=2πfL.

Isici sekhwalithi

Isici sekhwalithi u-Q inani elibonakalayo elimelela ikhwalithi yekhoyili, futhi i-Q iyinani le-XL ye-inductance ekumelaneni kwayo okulinganako, okungukuthi, Q = XL/R. i-inductor isebenza ngaphansi kwe-voltage ethile ye-AC. Ukuphakama kwevelu ye-Q ye-inductor, kuncane ukulahlekelwa kanye nokusebenza kahle okuphezulu. Inani elingu-q lekhoyili lihlobene nokumelana kwe-DC komqhubi, ukulahleka kwe-dielectric kwamathambo, ukulahlekelwa okubangelwa isihlangu noma insimbi core, ithonya lomphumela we-high frequency wesikhumba nezinye izici. Inani lika-q lekhoyili livamise ukuba ngamashumi kuya kumakhulu. Ikhwalithi yekhwalithi ye-inductor ihlobene nokumelana kwe-DC kwentambo yekhoyili, ukulahlekelwa kwe-dielectric kohlaka lwekhoyili kanye nokulahlekelwa okubangelwa umgogodla nesihlangu.
