He aha i puta ai te iahiko o te pou i te motuka?
Ko te iahiko i roto i te ara iahiko turanga-nohoanga o te motuka e mau ana i te poupou ka kiia ko te iahiko poupou.
Ngā take o te ia o te pou:
Te kore ōrite o te papa aukume;
He haurore kei roto i te iahiko o te pūtake hiko;
Kāore i te pai te hanga me te tāutanga, ka hua ake he āputa hau kāore i te ōrite nā te rerekētanga o te rotor;
He āputa kei waenganui i ngā haurua porowhita e rua o te matua pūmau ka taea te wetewete;
Kāore i te tika te maha o ngā wahi o te matua stator i hangaia e ngā rāngai whakarārangi.
Ngā Tūponotanga: Ka memeha te mata o te peera o te motuka, ka puta he pūwero moroiti rite ki ngā ira, ka kino ake te mahi a te peera, ka nui ake te ngaronga o te waku me te wera, ā, ka mutu ka wera te peera.
He aha e kore ai e taea te whakamahi i ngā motuka whānui i ngā rohe papatahi?
He pānga kino te teitei ki te pikinga o te pāmahana o te motuka, te korona motuka (te motuka ngaohiko teitei) me te whakawhiti i te motuka DC.
Me mārama ki ngā āhuatanga e toru e whai ake nei:
Ka teitei ake te teitei, ka nui ake te pikinga o te pāmahana o te motuka, ā, ka iti ake te mana whakaputa. Heoi, ina heke te pāmahana me te pikinga o te teitei kia ea ai te awe o te teitei ki te pikinga o te pāmahana, ka noho tonu te mana whakaputa kua whakatauria o te motuka;
Me mahi ngā mahi ārai i te mate korona ina whakamahia ngā motuka ngaohiko teitei ki ngā papa whenua;
Kāore i te pai te teitei mō te whakawhiti i te motuka DC, nō reira me aro nui ki te kōwhiringa o ngā rauemi paraihe waro.
He aha te take kāore e tika kia whakahaerehia te mōtini me te kawenga mama?
Ina oma te motuka me te kawenga mama, ka puta:
He iti te mana o te motuka;
He iti te whai huatanga o te motuka.
Ina oma te motuka me te kawenga mama, ka puta:
He iti te mana o te motuka;
He iti te whai huatanga o te motuka.
Ka maumauria ngā taputapu, ā, ka kore e whai hua te whakahaere.
He aha ngā take o te wera nui o te motuka?
He nui rawa te kawenga;
te wāhanga ngaro;
Kua āraia ngā paipa hau;
He roa rawa te wā e oma ana i te tere iti;
He nui rawa ngā harmonika o te pūtake hiko.
He aha ngā mahi me mahi i mua i te whakamahi i tētahi motuka kua roa te wā kāore i whakamahia?
Inehia te stator, te ātete whakamarumaru mai i te takai ki te wāhanga me te ātete whakamarumaru mai i te takai ki te whenua.
Me tutuki i te ātete whakamarumaru R te tātai e whai ake nei:
R＞Un/(1000+P/1000)(MΩ)
Un: ngaohiko whakatauranga o te takai motuka (V)
P: Mana mōtini (KW)
Mō te motuka Un=380V, R>0.38MΩ.
Mena he iti te ātete whakamarumaru, ka taea e koe te:
a: Ka oma te motuka me te kore kawenga mō te 2 ki te 3 hāora hei whakamaroke;
b: Whakamahia te iahiko whakawhiti iti-ngaohiko o te 10% o te ngaohiko whakatauranga hei whakawhiti ki roto i te takai, honoa rānei ngā takai toru-wāhanga i roto i te raupapa, kātahi ka tunua ki te iahiko tika kia mau tonu te iahiko ki te 50% o te iahiko whakatauranga;
c: Whakamahia he pā hau hei tuku i te hau wera, i tētahi wae whakamahana rānei hei whakamahana.
Horoia te motuka.
Whakakapia te hinu o te peera.
He aha e kore ai e taea e au te tīmata i te motuka i te taiao makariri i te wā e pai ai ahau?
Ki te roa rawa te pupuri i te mōta i roto i te taiao pāmahana iti, ka:
Kua pakaru te whakamarumaru o te motuka;
Ka huka te hinu o te peera;
Paura honohono ki ngā hononga waea.
Nō reira, me whakamahana te motuka, me rongoa hoki ki te taiao makariri, ā, me tirotirohia ngā takai me ngā whāriki i mua i te whakamahinga.
He aha ngā take o te kore taurite o te iahiko-toru-wāhanga i roto i te motuka?
Te kore taurite o te ngaohiko e toru-wāhanga;
He ngoikore te whakarewa, he ngoikore rānei te whakapā o tētahi peka āhuahanga i roto i te motuka;
Te takai a te motuka i te huringa poto-ki-te-huri, te huringa poto rānei ki te whenua, te huringa-ki-te-wāhanga rānei;
Hapa waea.
He aha e kore ai e taea te hono i te motuka 60Hz ki te pūtake hiko 50Hz?
I te hoahoatanga o te motuka, ko te pepa maitai silicon te tikanga kia mahi i roto i te rohe kukū o te pihi aukume. Ina pumau te ngaohiko hiko, mā te whakaiti i te auau ka piki ake te rerenga aukume me te ia whakaoho, ka hua ake te pikinga o te ia o te motuka me te ngaronga parahi, ā, i te mutunga ka piki ake te pāmahana o te motuka. I ngā wā tino kino, ka wera pea te motuka nā te wera nui o te koiri.
He aha ngā take o te ngaronga o te wāhanga o te motuka?
Pūtake hiko:
Te whakapā o te pana kāore i te pai;
Whakawhitiwhiti, wehenga rārangi rānei;
Kua pā te fuse.

Te ngoikore o te whakarewa waea ā-roto;
Kua pakaru te takai o te mōta.
He aha ngā pūtake o te wiri me te haruru rerekē o ngā motuka?
Ngā āhuatanga mīhini:
Te whakahinuhinu ngoikore o te peera me te kakahu o te peera;
Kua wetekina ngā tīwiri whakau;
He paru kei roto i te motuka.
Ngā āhuatanga hikohiko:
Te mahi taumaha rawa o te motuka;
Te kore taurite o te au-wāhanga-toru;
te wāhanga ngaro;
Ka puta he hapa ara iahiko poto i roto i ngā takai stator me te rotor;
E tuwhera ana te wāhanga whakarewa o te rotor whare herehere, ā, ka whati ngā pae.
He aha ngā mahi me mahi i mua i te tīmatanga o te motuka?
Inehia te ātete whakamarumaru (mō ngā motuka ngaohiko iti, kaua e iti iho i te 0.5MΩ);
Inehia te ngaohiko tuku hiko. Tirohia mēnā he tika te waea o te motuka, ā, mēnā kei te tutuki i te ngaohiko tuku hiko ngā whakaritenga;
Tirohia mēnā kei te pai te āhua o ngā taputapu tīmatanga;
Tirohia mēnā he pai te fiusi;
Tirohia mēnā kei te whenua te motuka, ā, he pai te hononga kore;
Tirohia te tuku mō ngā hapa;
Tirohia mēnā he pai te taiao mō te motuka, ā, tangohia ngā rauemi mura me ētahi atu paru.
He aha ngā take o te wera nui o te peera o te motuka?
Ko te motuka tonu:
He kikī rawa ngā mowhiti o roto, o waho hoki o te peera;
He raruraru kei roto i te āhua me te tūnga o ngā wāhanga, pērā i te ngoikore o te hononga o ngā wāhanga pērā i te turanga mīhini, te taupoki pito, me te pou;
Te kōwhiringa hē o ngā peera;
Kāore i te pai te whakahinuhinu i te peera, kāore rānei i te horoia ma te peera, ā, he paru kei roto i te hinu;
iahiko tuaka.
Whakamahinga:
Kāore e tutuki i ngā whakaritenga te tāutanga hē o te waeine, pērā i te hononga-axial o te pou motuka me te taputapu taraiwa;
He kuiti rawa te tō o te pūrakau;
Kāore ngā peera i te pai te tiaki, kāore i te rawaka te hinu, kua pau rānei te ora mahi, ā, ka maroke, ka pirau ngā peera.
He aha ngā take mō te iti o te ātete ārai o te motuka?
He mākū te takai, he uru mai rānei te wai;
Ka kohia te puehu, te hinu rānei ki runga i ngā takai;
Te koroheketanga o te whakamarumaru;
Kua pakaru te whakamarumaru o te mata o te mōtini, o te papa waea rānei.
