The atọ-adọ circuit

Isi ugbu a usoro nakweere ugbu a ala na-atọ-adọ na sekit na sekit, nke nwere ọtụtụ uru n'elu otu-adọ.

Atọ-adọ ugbu a usoro a na-akpọ atọ-adọ okwukwo N'ịbụ atọ electromotive agha ndị nwere otu njupụta ma ugboro ma gbanwere na-akwanyere onye ọ bụla ọzọ na-adọ site 120⁰ ma ọ bụ n'oge a nke atọ oge.

Onye ọ bụla iche iche circuit, dị a atọ-adọ usoro e kwuru iji belata na-adọ.

Adọ ugbu a, nke a rụrụ atọ-adọ circuit nwere ike enwetara site na ijikọta atọ nke otu generator, na-enye a otu-adọ nwetụ ugbu a, rotors, nke di na a ofu ọnọdụ, na-ọnwụ mmasị ọ bụla ọzọ na-adịghị agbanwe ọnọdụ ha n'oge adiana. Na nke a generator stator windings na-eketịbede onye ọ bụla ọzọ site 120⁰ na rotor n'akụkụ. N'ọnọdụ dị otú ahụ, ọ bụ nnọọ ihe doro anya na electromotive ike nke abụọ generator ga ekpela ha mgbanwe na mmekọrita mbụ generator na 120⁰, ie kacha uru nke electromotive ike nke n'otu uzo nke abụọ generator ga-abịa mgbe niile generator rotor ga atụgharị na 120⁰. The electromotive ike nke atọ generator ga-ga-egbu oge ikwu na abụọ generator 120⁰.

Ma ndị dị otú a usoro nke na-amị ugbu a, nke na-atọ-adọ circuit, bụghị akụ na ụba viable na nyochawa ihe ịma aka. Nnọọ mfe atọ stator windings jikọọ na otu ngwugwu. Ndị dị otú ahụ a generator na-akpọ generator adọ ugbu a.

N'ihi ya, stator alternator ugbu a nwere atọ windings (akpọ generator n'ụzọ), na 120⁰ obibi ikwu ọ bụla ọzọ. The rotor bụ ihe atọ na-adọ ugbu a generator na a rotor structurally yiri otu-adọ AC generator.

N'oge adiana nke rotor windings niile na-kere hà na ugboro na njupụta nke electromotive ike, ma ha na-agaghị n'out oge ruo ha kacha. Anya isi na kacha electromotive ike na-eme na oge nke Itie nke center nke ugwu osisi nke rotor ná mmalite nke asọfe, ọ dị mfe ịhụ na kacha electromotive ike nke n'otu uzo nke abụọ eriri igwe ga-abịa mgbe adiana nke rotor on 120⁰, na nke atọ - mgbe mbịne na 240⁰ ikwu na mbụ.

Ejikọta mpụga circuit ọ bụla na-adọ generator, anyị na-enweta atọ adọ ugbu circuit enweghị interconnected dịghị eletriki njikọ, ebe onye ọ bụla iche iche circuit okwukwo n'otu ha na-eguzogide ga-hà na njupụta ma gbanwere na-adọ ikwu onye ọ bụla ọzọ na-na 120⁰.

Iji jikọọ dị otú ahụ a generator ka mpụga circuit, mkpa isii wires. Iji belata ọnụ ọgụgụ nke wires na-aga mpụga circuit, ọ dị mkpa ijikọ erite eriri igwe na generator interconnected etolite electrically tinyere na atọ-na-adọ usoro. Njikọ a nwere ike mere abụọ dị iche iche: a triangle na a kpakpando.

Ma ogige eme ka o kwe ịzọpụta ihe onwunwe ke nnyefe nke otu ike si atọ onwe ha atọ na-adọ generators.

Atọ-adọ na sekit na sekit ka o kwe omume ike a dị mfe ma adaba n'ihi na ngwaọrụ rụọ ọrụ na electric moto, nke a na-akpọ asynchronous. Ya na ngwaọrụ dabeere na ngwa nke n'usoro ndọta. Na mfe ikpe, a ndọta nwere ike enwetara site n'usoro ndị akpukponu inyinya magnet.

Ọ bụrụ na ubi-etinye a n'usoro n'usoro mechiri emechi eduzi, kpọgidere na axis, na ndọta ya adiana intersecting n'akụkụ circuit-eduzi eji ihe electromotive ike nime ya itinye n'ọkwa na site na ihe itinye n'ọkwa ugbu a na a mechiri emechi akaghị. Nke a ugbu a na inwe mmekọrịta na ndọta nke n'usoro magnet eriri igwe ga bugharia. amama ntụziaka nke adiana kpebisiri ike site na iji aka ekpe na-achị.

Atọ adọ Motors na-ekewet nke abụọ n'akụkụ: a n'usoro n'usoro akụkụ - na rotor na anyịnya - na stator.

The n'usoro ndọta na-eme n'ime engine bụghị site n'ibu adiana nke magnetik okporo osisi, na na a eruba n'ime nwetụ ugbu a nke ofu-adọ stator windings.

Atọ-adọ na sekit na sekit na-e site otu nke kasị ukwuu eletriki injinia nke XIX na n'oge XX narị afọ. - Russian engineer knife Dolivo-Dobrovolsky (1862-1919). Nke a usoro meghere ezigbo ohere maka ulo oru eji ọkụ eletrik. Ihe kacha mkpa bụ:

• ego na wiring akara ejikọta ọdụ ka n'ji;
• ekwe omume nke n'usoro ndọta etinyere na atọ-na-adọ Motors.
