Olelo mua

ʻElua mau manaʻo like ʻole ka pono a me ka mana.ʻO ka maikaʻi o ke kaʻa e pili ana i ka ratio o ka mana hoʻopuka o ke kaʻa i ka mana i lawe ʻia e ka motika mai ka pahu, a ʻo ke kumu mana e pili ana i ka ratio o ka mana ikaika o ka mīkini i ka mana ʻike.ʻO ke kumu mana haʻahaʻa ka mea e hoʻoulu ai i ka manawa reactive nui a me ka hāʻule ʻana o ka uila pale laina nui, ka hopena i ka haʻahaʻa haʻahaʻa.Piʻi ka mana hana ma muli o ka piʻi ʻana o nā poho laina.He haʻahaʻa ke kumu mana, a ʻaʻole i hoʻonohonoho ʻia ka volta a me ke au; i ka wā e kahe ana ke au i loko o ke kaʻa, piʻi ka mana o ke kaʻa, kiʻekiʻe ka mahana, a haʻahaʻa ka torque, kahi e hoʻonui ai i ka nalowale o ka mana o ka pā.

Ka nānā 'ana i ka ikehu ho'ōla o ka 'oi loa-ki'eki'e 'oihana magnet mau loa

1. Hoʻohālikelike i ka hopena mālama ola

He ʻoi aku ka ʻoi aku ka maikaʻi o ka mīkini YX3 pae ʻekolu ma mua o ka mīkini Y2 maʻamau maʻamau, a me ka mīkini paʻa paʻa synchronous.ʻoi aku ka maikaʻi a me ka mana kumuʻoi aku ka maikaʻi o ka ikehu YX3 ʻekolu, no laila ʻoi aku ka maikaʻi o ka hopena o ka ikehu.

2. Ka laʻana o ka mālama ʻana i ka ikehu

ʻO ka hoʻokomo o kēia manawa o ka mīkini magnet paʻa me ka mana nameplate o 22 kW he 0.95, ka mea mana 0.95 a me ka Y2 kaʻa kaʻa 0.9, ka mana mana 0.85: I=P/1.73 × 380 ×cosφ·η=44A, ka hoʻokomo o ka mau loa. kaʻa magnet I kēia manawa: I=P/1.73×380×cosφ·η=37A, ʻo ka ʻokoʻa hoʻohana o kēia manawa he 19%

3. Ka mana ike

ʻO ke kaʻa Y2 P=1.732UI=29 kW kaʻa makamae mau loa P=1.732UI=24.3 kW ka ʻokoʻa hoʻohana mana he 19%

4. Ka hoʻohana ʻana i ka ikehu hoʻonui hapa

Ke hāʻule nui nei ka maikaʻi o nā kaʻa Y2 ma lalo o ka 80% ukana, a hāʻule nui ka mana mana. Hoʻomau mau nā kaʻa magnet paʻa i ka hana kiʻekiʻe a me ka mana ma waena o 20% a me 120% mau ukana. Ma nā haawe hapa, nā motika magnet mauloaʻaʻOi aku ma mua o 50% ka mālama ʻana i ka ikehu

5. ʻO ka hoʻohana ʻana i ka loiloi hana pono ʻole

ʻO ke ʻano reactive o ka mīkini Y2 ma kahi o 0.5 a 0.7 mau manawa i ka manawa i helu ʻia, kokoke ka mana o ka mīkini paʻa paʻa i ka 1, a ʻaʻohe mea e koi ʻia i kēia manawa, no laila ka ʻokoʻa ma waena o ke ʻano reactive o ka mīkini magnet mau loa. a ʻo ka motor Y2 ma kahi o 50%.

6. Hoʻokomo ʻia ka ʻike uila uila

Ua ʻike pinepine ʻia inā hoʻololi ka mīkini paʻa paʻa i ka mīkini Y2, e piʻi ka uila mai 380V a i 390V. ʻO ke kumu: ʻO ke kumu haʻahaʻa haʻahaʻa o ka mīkini Y2 e hoʻoulu ai i kahi ʻano reactive nui, a ma ia mea e hoʻoheheʻe nui ʻia ma muli o ke kūpaʻa o ka laina, e hopena i ka haʻahaʻa haʻahaʻa. He kumu mana kiʻekiʻe ka mīkini magnet paʻa, hoʻopau i ka huina haʻahaʻa haʻahaʻa, a hoʻemi i ka hāʻule o ka laina laina, e hopena i ka piʻi ʻana o ka volta.

7. Kaʻa kaʻa pahee ana

Loaʻa nā motika Asynchronous i ka paheʻe o 1% a 6%, a holo like nā motika magnet paʻa me ka paheʻe o 0. No laila, ma lalo o nā kūlana like, ʻo ka hana ʻana o nā ʻenekini mau loa he 1% a 6% kiʻekiʻe ma mua o ka Y2 motors. .

8. Kaʻa kaʻa pohō iho ana

Loaʻa i ka 22 kW Y2 kaʻa kaʻa he 90% a me ka nalowale iā ia iho o 10%. ʻOi aku ka nalowale o ke kaʻa ma mua o 20,000 kilowatts i hoʻokahi makahiki o ka hana mau ʻole; ʻo 95% ka maikaʻi o kahi kaʻa magnet mau loa, a ʻo kona poho iho he 5%. Ma kahi o 10,000 kilowatts, ʻo ka lilo ʻana iho o ka mīkini Y2 ʻelua ʻelua o ka mīkini magnet mau loa.

9. Ka nānā 'ana o ka power factor ka uku aupuni a me ka papa ho'opa'i

Inā he 0.85 ka mana o ka mīkini Y2, 0.6% o ka uku uila e uku ʻia; inā ʻoi aku ka nui o ka mana ma mua o 0.95, e hoʻemi ʻia ka uku uila e 3%. Aia he 3.6% kumu kūʻai ʻokoʻa i nā uku uila no nā kaʻa uila mau loa e pani ana i nā motika Y2, a ʻo ka waiwai o ka uila no hoʻokahi makahiki o ka hana mau ʻana he 7,000 kilowatts.

10. Ka Ike ana o ke kanawai o ka malama ana i ka ikehu

ʻO ka helu mana ka ratio o ka hana pono i ka mana ʻike. He haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa ka mana o ka mīkini Y2, ka nui o ka hoʻohana ʻana i ka mana absorption, a me ka hoʻohana ʻana i ka ikehu kiʻekiʻe; Loaʻa ka mana mana kiʻekiʻe, ka helu hoʻohana absorption maikaʻi, a me ka hoʻohana haʻahaʻa haʻahaʻa

11. Kānāwai Lepili Hoʻonaʻauao Lahui

ʻO ka pae ʻelua o ka ikaika o ka ikehu o ka mīkini paʻa mau loa: ka mīkini hoʻopakele ikehu YX3 kaʻa Papa-ʻekolu ka ikaika o ka ikehu: hoʻopau ʻia ka mīkini Y2 maʻamau.

12. Mai ka nānā 'ana i nā ha'awina e pono ai ka ikehu aupuni

ʻOi aku ka kiʻekiʻe o ka haʻawina aupuni no nā kaʻa kaʻa me ka ʻoi aku ka maikaʻi o ka ikehu pae ʻelua ma mua o kēlā no nā kaʻa hoʻokele ikehu pae ʻekolu. ʻO ka manaʻo e hoʻopakele i ka ikehu mai ka hui holoʻokoʻa, i mea e hōʻoia ai i ka hoʻokūkū o ka ʻāina i ka honua. Mai kahi hiʻohiʻona honua, inā hoʻohana nui ʻia nā mīkini magnet mau loa, e hoʻomaikaʻi ʻia ke kumu mana o ka mea kanu holoʻokoʻa, me ka nui o ka uila uila holoʻokoʻa, ʻoi aku ka maikaʻi o ka mīkini, ka poho laina haʻahaʻa, a me ka hana wela o ka laina haʻahaʻa.

Ua ʻōlelo ka mokuʻāina inā aia ka mana ma waena o 0.7-0.9, e uku ʻia ka 0.5% no kēlā me kēia 0.01 haʻahaʻa ma mua o 0.9, a e uku ʻia ka 1% no kēlā me kēia 0.01 haʻahaʻa ma mua o 0.7 ma waena o 0.65-0.7, a ma lalo o 0.65, kēlā me kēia haʻahaʻa ma mua o 0.65. 0.65 Inā he 0.6 ka helu mana o ka mea hoʻohana,alailaʻo ia (0.9-0.7)/0.01 X0.5% + (0.7-0.65)/0.01 X1% + (0.65-0.6)/0.01X2%= 10%+5%+10%=25%

 

Nā loina kikoʻī

ʻAʻohe paheʻe o ka rotor, ʻaʻohe hoʻoulu uila, a ʻaʻohe mea hao hao a me ka poho keleawe. He kumu mana kiʻekiʻe ko ka rotor no ka mea, loaʻa i ka magnet paʻa kona māla ponoʻī a ʻaʻole koi i ka manawa hoʻoulu hou. ʻOi aku ka liʻiliʻi o ka mana reactive, hoʻemi nui ʻia ke au o ka stator, a hoʻemi nui ʻia ka poho keleawe stator. Ma ka manawa like, no ka mea, ʻoi aku ka nui o ka coefficient pole arc o ka ʻenekini paʻa mau loa ma mua o ka mīkini asynchronous, i ka wā e mau ai ka volta a me ka stator structure, ʻoi aku ka liʻiliʻi o ka induction magnetic awelika o ka mīkini ma mua o ka asynchronous. moto, a he uuku ka hao. Hiki ke ʻike ʻia ʻo ka honua rare permanent magnet synchronous motor e mālama i ka ikehu ma ka hōʻemi ʻana i kona mau poho like ʻole, a ʻaʻole pili ʻia e nā loli i nā kūlana hana, ka honua a me nā mea ʻē aʻe.

ʻO nā hiʻohiʻona o ka mīkini paʻa magnet synchronous

1. ʻO ke kūlana kiʻekiʻe

ʻOi aku ka nui o ka mālama mana ma mua o 10%. Ke hāʻule wikiwiki nei ka pihi kūpono o ka mīkini Y2 asynchronous ma 60% o ka ukana helu, a haʻahaʻa loa ka hana ma ka haʻahaʻa māmā. He kiʻekiʻe a palahalaha ka pihi kūpono o ka mīkini magnet mau loa, a aia ma kahi kiʻekiʻe ma 20% a 120% o ka ukana helu. wahi kūpono.Wahi a nā ana ma ka pūnaewele e nā mea hana he nui ma lalo o nā kūlana hana like ʻole, ʻo 10-40% ka nui o ka mālama ʻana i ka mana o nā motor synchronous magnet mau loa.

2. Kiʻekiʻe mana kumu

ʻO ke kumu mana kiʻekiʻe, kokoke i ka 1: ʻaʻole pono ka mīkini hoʻoheheʻe hoʻohālikelike mau loa i kēia manawa, no laila ua kokoke ka mana mana i ka 1 (ʻo ia hoʻi ka capacitive), ke kiʻekiʻe a pālahalaha ka mana o ka mana a me ka pihi kūpono, kiʻekiʻe ke kumu mana. liʻiliʻi ka stator i kēia manawa, a ua hoʻemi ʻia ka poho keleawe stator, hoʻomaikaʻi i ka pono. Hiki ke hōʻemi a hoʻopau paha i ka mana mana reactive capacitor. I ka manawa like, ʻo ka uku o ka mana reactive o ka mīkini magnet mau loa ka uku manawa maoli ma ka pūnaewele, ka mea e hoʻomau i ka mana o ka hale hana, he mea maikaʻi loa ia i ka hana maʻamau o nā mea hana ʻē aʻe, e hōʻemi ana i ka mana reactive. nalo o ka lawe uwea ma ka hale hana, a loaa ka hopena o ka hoopakele ikehu piha.

3. He liʻiliʻi ke au o ka moto

Ma hope o ka lawe ʻia ʻana o ke kaʻa magnet paʻa, e emi nui ke ʻano o ka mīkini. Hoʻohālikelike ʻia me ka kaʻa Y2, ʻo ka mīkini paʻa mau loa ka hoʻemi nui ʻana o ka mīkini kaʻa ma o ke ana maoli ʻana. ʻAʻole pono ka mīkini paʻa paʻa i ka hoʻoulu hou ʻana, a ua hoʻemi nui ʻia ke ʻano o ka mīkini. Hoʻemi ʻia ka poho o ka hoʻouna ʻana i ke kaula, ʻo ia ka mea e like me ka hoʻonui ʻana i ka hiki o ke kaula, a hiki ke hoʻokomo ʻia nā ʻoi aku o nā kaʻa ma ke kaula hoʻouna.

4. ʻAʻohe paheʻe i ka hana, paʻa ka wikiwiki

ʻO ka moto magnet paʻa he motika synchronous. ʻO ka wikiwiki o ke kaʻa e pili wale ana i ke alapine o ka mana. Ke hana nei ka motika 2-pole ma lalo o kahi lako mana 50Hz, paʻa paʻa ka wikiwiki ma 3000r/min.ʻAʻole nalo ka hoʻololi ʻana, ʻaʻohe paheʻe, ʻaʻole i hoʻopilikia ʻia e ka fluctuation voltage a me ka nui o ka ukana.

5. ʻO ka piʻi ʻana o ka mahana he 15-20 ℃ haʻahaʻa

Ke hoʻohālikelike ʻia me ka motor Y2, liʻiliʻi ka nalowale o ke kūpaʻa o ka mīkini magnet mau loa, ua hoʻemi nui ʻia ka nui o ka poho, a ua hoʻemi ʻia ka piʻi ʻana o ka wela o ka mīkini.Wahi a ke ana maoli, ma lalo o nā kūlana like, ʻo ka mahana hana o ka mīkini magnet mau loa he 15-20 ° C haʻahaʻa ma mua o ka mīkini Y2.
