Kedu njikọ dị n'etiti triangle na kpakpando na uru na ọghọm ya?

Otu ihemoto nke usoro atọenwere ike ijikọ ya site na njikọ triangle, nke kwekọrọ na obere voltaji; Enwere ike ijikọ ya dịka usoro njikọ kpakpando si dị, nke kwekọrọ na nnukwu voltaji; Voltaji dị elu bụ okpukpu atọ nke mgbọrọgwụ square nke obere voltaji. Dịka ọmụmaatụ, moto 380V nwere njikọ triangle, ọ bụrụ na ejikọtara ya na njikọ kpakpando, voltaji kwekọrọ na ya bụ 660V. Njikọ kpọmkwem kwesịrị ịdị ka voltaji ọkọnọ ike.

Moto nke jikọtara kpakpando anaghị emepụta mgbasa n'ime, nke ka mma n'echiche karịa njikọ triangle.
Ebe ọ bụ na enweghị ike ịhazigharị usoro atọ ahụ nke ọma, enwere obere ọdịiche mgbe niileMoto nke atọvoltaji, nke ga-emepụta mgbasa n'ime triangle ahụ, na-ebute okpomọkụ na mbelata arụmọrụ moto. A na-emekwa njikọ triangle ahụ maka ihe ndị mere eme, ya bụ, ihe a na-akpọ mmalite kpakpando-triangle, mmalite kpakpando-triangle nwere ike ibelata ọkụ mmalite nke ọma, mana ọ ga-ebelata ike mmalite, yabụ enwere ike iji ya naanị na ọnọdụ ibu dị mfe ma ọ bụ enweghị ibu.

Anyị na-ahụ na enwere ike iji kpakpando-triangle malite moto fan pump, mana n'ezie enweghị mmalite kpakpando-triangle na kreen, a na-amalite ibuli elu site na iguzogide usoro rotor winding, gịnị kpatara o ji dị oke njọ, enwere ihe kpatara ya. N'ezie, ọnọdụ ugbu a nke ịmalite mgbanwe ugboro ugboro edozila nsogbu ndị dị otú ahụ kpamkpam.

N'agbanyeghị usoro waya atọ ma ọ bụ waya anọ (na-enweghị ala), akụkụ eletriki dị n'etiti voltaji atọ ahụ bụ ọdịiche nke ogo 120 n'okpuru ọnọdụ dị mma. A na-eche na n'ihi nnyonye anya oge, a na-emepụta harmonics 3N na winding nke terminal ibu, 3N*120=360N, nke na-egosi na terminal voltaji harmonic nke 3N nke phase atọ ahụ bụ otu kpọmkwem, ọ bụrụ na obosara ya bụ otu, a ga-akagbu harmonics 3N nke otu atọ nke voltaji ahịrị kpamkpam, ya bụ, enweghị integer multiple harmonics nke 3 na voltaji dị n'etiti ahịrị ndị ahụ.

Maka njikọ triangle, a na-agbagharị ọkụ harmonic 3N dị n'elu n'otu oge ahụ na triangle a ma debe ya na triangle a iji mepụta mgbasa na-enweghị njedebe. Ya mere, maka ọnụnọ nke harmonics, enwere ike ịhọrọ njikọ triangle ma ọ bụ kpakpando dabere ma harmonic 3N ga-ekwe omume na voltaji ma ọ bụ ugbu a.
