A. He pai te haumaru o te hua me te ātete kaha ki te ngaohiko nui

Nā te mea he āhuatanga whakaora-ā-koe anō ngā pūnga kiriata, ā, kua hangaia kia rite ki te paerewa 1EC61071, he nui ake te ātete ngaohiko ngaru o te pūnga i te 1.5 o te ngaohiko kua whakatauria. Hei tāpiri, ka whakamahia e te pūnga te hangarau kiriata wehewehe, nō reira kāore te pūnga e whakaputa i te pakaru o te ara iahiko poto i roto i te ariā, e tino whakapai ake ana i te haumaru o tēnei momo pūnga. Ko te aratau rahunga noa ko te ara iahiko tuwhera. I roto i ngā tono motuhake, he tohu nui hoki te ātete ngaohiko tihi o te pūnga mō te aromatawai i ngā pūnga. Inaa, mō ngā pūnga hikohiko, ko te ngaohiko ngaru mōrahi e whakaaetia ana he 1.2 ngā wā, e akiaki ana i ngā kaiwhakamahi ki te whakaaro ki te ngaohiko tihi kaua ki te ngaohiko ingoa.

B. Ngā āhuatanga pāmahana pai, he whānui te awhe pāmahana hua, mai i -40C-105C

Ko te kiriata polypropylene pāmahana-tiketike e whakamahia ana i roto i te pūnga kiriata tautoko DC he pumau pāmahana kāore i te kiriata polyester me ngā pūnga hiko. I te pikinga o te pāmahana, ka heke te kaha o te pūnga kiriata polypropylene katoa, engari he tino iti te ōwehenga whakaheke, tata ki te 300PPM/C; ko te kaha o te kiriata polyester ka nui ake te rerekētanga me te pāmahana, ahakoa i te wāhanga pāmahana teitei, i te wāhanga pāmahana iti rānei, arā, +200~+600PPM/C.

C. Ngā āhuatanga auau pumau, ngā āhuatanga auau-tiketike pai o te hua

I tēnei wā, ko te nuinga o ngā auau whakawhiti a te kaiwhakahaere he tata ki te 10K HZ, e hiahia ana kia pai te mahi auau-teitei o te hua. Mō ngā pūnga hiko me ngā pūnga kiriata polyester, he raruraru tēnei whakaritenga.

D. Kāore he polarity, ka taea te tu atu i te ngaohiko whakamuri

Ko ngā irahiko o ngā pūnga kiriata he konganuku nano-tauine kua whakatakotoria ki runga i ngā kiriata angiangi. Kāore he polarity o te hua, nō reira he tino watea mō ngā kaiwhakamahi, ā, kāore he take ki te whakaaro ki ngā pou pai me ngā pou kino. Mō ngā pūnga hikohiko, ki te neke atu i te 1.5 ngā wā o te Un te ngaohiko whakamuri e pā ana ki te pūnga hikohiko, ka puta he tauhohenga matū i roto i te pūnga. Ki te roa te roa o tēnei ngaohiko, ka pahū te pūnga, ka rere rānei te irahiko i te wā e tukuna ana te pēhanga o roto o te pūnga.

E. E hiahiatia ana ngā ngaohiko teitei, kāore he ātete raupapa me te taurite

Hei whakanui ake i te mana whakaputa, kei te piki haere te ngaohiko pahi o ngā waka ranu me ngā waka pūtau wahie. Ko ngā ngaohiko pākahiko e tukuna ana ki ngā motuka i te mākete ko 280V, 330V me te 480V. He rerekē ngā pūnga e rite ana ki a rātou i ngā kaihanga rerekē, engari ko te tikanga he 450V, 600V, 800V, ā, ko te kaha kei waenga i te 0.32mF ki te 2mF. Kāore te ngaohiko whakatauranga o ngā pūnga hiko e teitei ake i te 500V, nō reira, ina teitei ake te ngaohiko pahi i te 500V, ka taea anake e te pūnaha te whakapai ake i te taumata ngaohiko ātete o te pēke pūnga mā te hono i ngā pūnga hiko i roto i te raupapa. Mā tēnei, ehara i te mea ko te rahinga me te utu o te pēke pūnga ka piki ake, engari ko te inductance me te ESR i roto i te ara iahiko ka piki ake.

F. ESR iti, ātete au ripo kaha

He nui ake te kaha o te pūnga kiriata i te 200mA/μF, ā, ko te kaha o te iahiko riporiko he 20mA/μF. Ka taea e tēnei āhuatanga te whakaiti nui i te kaha o te pūnga e hiahiatia ana i roto i te pūnaha.

G. ESL iti

Nā te iti o te hiko o te inverter, me tino iti te hiko o tōna wāhanga matua, te pūnga DC-Link. Ka whakauruhia e ngā pūnga kiriata tātari DC-Link teitei te pae pahi ki roto i te kōwae pūnga hei whakaiti i tōna hiko-ā-roto (<30nH), ka tino whakaiti i te pānga wiri i te auau whakawhiti e tika ana. Nō reira, he maha ngā wā ka mahue te pūnga mimiti e hono ana i te pūnga DC-Link, ā, ka hono tika te hiko pūnga ki te IGBT.

H. Ātete kaha o te aukume

Ka taea e ia te tu atu i ngā iahiko nui ohorere. Mā te hangarau tapahi ngaru me te hangarau whakamātotoru paninga pūnga ka taea te whakapai ake i te pāmahana iahiko ngaru me ngā āheinga ru miihini o te hua.

J. Te roa o te ora ratonga

Ko ngā āhuatanga kore-pakeke o te kiriata e whakatau ana he roa te ora o te pūnga kiriata, inā koa i te ngaohiko whakatauranga me te pāmahana whakahaere whakatauranga, ko te ora ratonga he nui ake i te 15000-20000 hāora; ki te 30Km/H te toharite, ka taea e ia te 450000Km i roto i te ora ratonga, ā, he rawaka te ora pūnga mō te maero o te motuka.

 

Ko ngā pūnga kiriata DC-LINK mahi-teitei he pūnga e whakamahi ana i ngā tukanga hanga hou me te hangarau kiriata whakarewa. Ka whakanui ake i te kiato pūngao o ngā pūnga kiriata tuku iho, ko te tikanga ka whakaitihia hoki te rahi o ngā pūnga. I tētahi atu taha, ka whakauruhia te matua pūnga me te pae pahi hei whakatutuki i ngā whakaritenga rahi ngāwari a ngā kiritaki, e kore e hanga noa i te waeine inverter katoa kia kiato ake, engari ka whakaitihia hoki te kaha hiko i roto i te ara iahiko tono, ka hanga kia pumau ake te mahi ara iahiko. Ko te hoahoa ara iahiko e whakamahia ana i roto i ngā waka hiko he ngaohiko teitei, he iahiko whai hua teitei, he ngaohiko nui rawa atu, he ngaohiko whakamuri, he iahiko tihi teitei, me ngā whakaritenga roa o te ora. Ko ngā pūnga kiriata te mea tino pai mō ngā waka hiko hei pūnga tautoko DC.
