Synchronous injini - zvakanakira nekuipira

Yainyanya kushandiswa zvakadai muchina somunhu synchronous injini iri awana imwe indasitiri apo pane yemagetsi kumhanya ari kugara nokukurumidza. Somuenzaniso, compressors pamwe michini simba, pumps actuators. Uyewo, munhu synchronous injini chinhu chinokosha, uye vazhinji midziyo neimba, zvakadai sezvachinoitwa maawa.

Nheyo nokushanda muchina uyu nyore. The kukurukurirana pamusoro kutenderera remagineti pamusoro armature neve rakatumbuka kuitika uye rinobva minda pamusoro inductor matanda wakadenha kugara Kuyerera hwaro nheyo kushanda mumwe mudziyo akadai synchronous electric motor. Kazhinji, munhu inductor iri rotor, uye chinotsigisa - iri stator. Simba injini sezvo nematanda vachishandisa electromagnets. Asi pane mhando kuderedzwa simba - a synchronous injini ine magnets a zvachose. Musiyano mukuru pakati synchronous uye asynchronous michina - stator uye rotor magadzirirwo.

Kuti mhanyisa injini kusvikira yavose sezvavakatarirwa akurumidze pamwero dzinowanzotaura asynchronous nzira. In nzira iyi, iyo inductor ichitenderera pfupi-circuited. Mushure injini inoenda yavose sezvavakatarirwa akurumidze, kuti rectifier anopa DC inductor. chezita nokukurumidza chete synchronous injini anogona kushanda vakazvimiririra.

injini kwakadaro rakanakira zvakawanda. Ndiye ane hurongwa unokosha zvikuru kunzwisisa asynchronous muchina, asi izvi zvaizopedza nemashoko akawanda zvakanakira. Mumwe mukuru zvakanakira - kukwanisa kwayo kushanda pasina kudyiwa reactive simba kana rova. Saka injini simba chokufunga akaenzana kubatana. Under izvi mamiriro, munhu synchronous AC injini ndiyo chete kushingaira zvinoriumba mutoro Network. A divi nezvinozoitika kuderedza injini saizi (ive induction injini, kuti stator ichitenderera rinowanikwa uye zvinoshingaira uye reactive dzenzvimbo pamusoro). Zvisinei, mashoko synchronous injini anogona vaunze chaiye uye reactive simba, anoshandira overexcitation muoti.

The synchronous injini iri zvikuru haanyanyi nokufamba uye voltage anodonhedza mu pemambure. Sewevhu mota yemagetsi vane yepamusoro kuramba overloads. zvinogoneka kuti kuwedzera zadzisa kugona pamusoro injini nokuwedzera kuti excitation ano. Kunakisa pamwe synchronous muchina ndiyewo chenguva chezita rotational nokukurumidza chero mutoro (kunze zadzisa).

Pasina mubvunzo, zvakadai muchina somunhu synchronous injini ine utera ayo. Vari chokuita dzakakwirira mari uye kunzwisisa mashandiro. The chikuru dambudziko ndiro excitation pamusoro injini yayo okusuma kupinda synchronism. Pari kuwanikwa kupararira thyristor exciters, vane yakakwirira zvikuru kunyatsoshanda, pane kuti dzemagetsi utachiona. Zvisinei, mari yavo yakakwirira zvikuru. Uchishandisa thyristor chinja anogona kugadzirisa matambudziko yakawanda: Zvakanyanya Kunaka Panguva Yepamuviri excitation ano murau, inotsigira cosine vaFiristiya kugara kukosha, kudzorwa voltage pamusoro tai, kudzora stator dzenzvimbo uye rotor iri zvashata muoti, uye nyaya zadzisa.
