Puranga Utu 800V "Ngā Kaupapa Taketake o te Utu"
Ko te nuinga o tēnei tuhinga e kōrero ana mō ētahi whakaritenga tuatahi mō te 800Vngā puranga utu, tuatahi, me titiro tātou ki te kaupapa o te utu: Ina honoa te pito utu ki te pito o te waka, ka tukuna e te puranga utu (1) te hiko DC āwhina iti-ngaohiko ki te pito o te waka hei whakahohe i te BMS (pūnaha whakahaere pākahiko) kua hangaia i roto i te waka hiko. I muri i te whakahohenga, (2) honoa te pito o te waka ki te pito puranga, whakawhitihia ngā tawhā utu taketake pēnei i te mana tono utu mōrahi o te pito waka me te mana putanga mōrahi o te pito puranga, i muri i te ōrite tika o ngā taha e rua, ka tukuna e te BMS (pūnaha whakahaere pākahiko) o te pito waka ngā mōhiohio tono hiko ki teteihana utu hiko, me tepuranga utu waka hikoka whakarerekē i tōna ake ngaohiko me te iahiko putanga kia rite ki ēnei mōhiohio, ā, ka tīmata mana te utu i te waka, koinei te kaupapa matua ohononga utu, ā, me mōhio tātou ki tēnei mea i te tuatahi.
Te utu 800V: "te whakanui i te ngaohiko, te iahiko rānei"
I roto i te ariā, ki te hiahia tātou ki te whakarato i te mana utu hei whakapoto i te wā utu, e rua ngā huarahi: ko te whakanui ake i te pākahiko, ko te whakanui ake rānei i te ngaohiko; E ai ki a W=Pt, ki te takiruahia te mana utu, ka haurua noa te wā utu; E ai ki a P=UI, ki te takiruahia te ngaohiko, te iahiko rānei, ka taea te takirua i te mana utu, kua whakahuatia tonutia tēnei, ā, e kiia ana he tikanga noa.
Mena he nui ake te ia, e rua ngā raruraru ka pā mai, ko te nui ake o te ia, ko te nui ake, ko te matotoru ake hoki o te taura e hiahia ana ki te ia, ka nui ake te diameter me te taumaha o te waea, ka piki ake te utu, ā, kāore e watea mō ngā kaimahi ki te whakahaere; Hei tāpiri, e ai ki te Q=I²Rt, ki te nui ake te ia, ka nui ake te ngaronga hiko, ā, ka whakaatahia te ngaronga i roto i te ahua o te wera, ka nui ake hoki te pēhanga o te whakahaere wera, nō reira kāore e kore kāore e tika kia whakanuia te mana utu mā te whakanui tonu i te ia, ahakoa he utu, he pūnaha taraiwa rānei i roto i te motuka.
Ki te whakataurite ki te utu tere tere,te utu tere ngaohiko teiteihe iti ake te wera e whakaputa ana, he iti ake hoki te mate, ā, kua whakamahia e te nuinga o ngā kamupene motuka matua te ara o te whakanui ake i te ngaohiko, mō te utu tere ngaohiko teitei, e ai ki te ariā ka taea te whakapoto i te wā utu mā te 50%, ā, mā te pikinga o te ngaohiko ka taea hoki te whakanui ake i te mana utu mai i te 120KW ki te 480KW.
Te utu 800V: "Ngā pānga wera e pā ana ki te ngaohiko me te iahiko"
Ahakoa he whakanui i te ngaohiko, he whakanui rānei i te iahiko, tuatahi, me te pikinga o tō kaha utu, ka puta tō wera, engari he rerekē te whakaaturanga wera o te whakanui i te ngaohiko me te whakanui i te iahiko. Heoi, he pai ake te mea tuatahi.
Nā te iti o te ātete e pā ana ki te iahiko i te wā e haere ana i roto i te ara iahiko, ka whakaitihia te rahi o te taura e hiahiatia ana e te tikanga whakanui ngaohiko, ā, ka iti ake te wera e tukuna ana, ā, i te mea ka piki ake te iahiko, ka nui ake te whānui o waho me te taumaha o te taura i te pikinga ake o te horahanga whakawhiti e kawe ana i te iahiko, ā, ka piki haere te wera i te roanga o te wā utu, he mea huna ake, he nui ake te mōrearea ki te pākahiko.
Te utu 800V: "Ētahi wero tonu ki ngā puranga utu"
He rerekē anō hoki ngā whakaritenga mō te utunga tere 800V i te pito puranga:
Mena mai i te tirohanga ā-tinana, me te pikinga o te ngaohiko, ka piki ake te rahi o te hoahoa o ngā taputapu e pā ana, hei tauira, e ai ki te taumata parahanga o te IEC60664 he 2, ā, ko te tawhiti o te rōpū rauemi whakamarumaru he 1, me noho te tawhiti o te taputapu ngaohiko-tiketike mai i te 2mm ki te 4mm, ā, ka piki ake anō hoki ngā whakaritenga ātete whakamarumaru, me tata te tawhiti ngoki me ngā whakaritenga whakamarumaru me whakaneke rua, me hanga anō tēnei i roto i te hoahoa ki te whakataurite ki te hoahoa pūnaha ngaohiko o mua, tae atu ki ngā hononga, ngā pae parahi, ngā hononga, me ētahi atu. Hei tāpiri, ko te pikinga o te ngaohiko ka arahi anō hoki ki ngā whakaritenga teitei ake mō te tinei pewa, ā, me whakapiki ake i ngā whakaritenga mō ētahi taputapu pēnei i ngā fiusi, ngā pouaka pana, ngā hononga, me ētahi atu, e pā ana hoki ki te hoahoa o te motuka, ka whakahuatia i roto i ngā tuhinga e whai ake nei.
Me tāpiri e te pūnaha utu hiko 800V teitei he pūnaha whakamatao wai hohe o waho e ai ki te kōrero i runga ake nei, ā, kāore e taea e te whakamatao hau tuku iho te whakatutuki i ngā whakaritenga ahakoa he whakamatao hohe, he whakamatao kore rānei, me te whakahaere wera o teteihana utu waka hikoKo te raina pū ki te pito o te waka he teitei ake i mua, ā, me pēhea te whakaiti me te whakahaere i te pāmahana o tēnei wāhanga o te pūnaha mai i te taumata taputapu me te taumata pūnaha te kaupapa hei whakapai ake me te whakatau e ia kamupene a muri ake nei; Hei tāpiri, ko tēnei wāhanga o te wera ehara i te wera anake i kawea mai e te utu nui rawa, engari ko te wera hoki i kawea mai e ngā taputapu hiko auau-teitei, nō reira me pēhea te mahi aroturuki wā-tūturu me te pumau, whai hua me te haumaru ki te tango i te wera he mea tino nui, ehara i te mea he whanaketanga rauemi anake, engari he kitenga pūnaha hoki, pērā i te aroturuki wā-tūturu me te whai hua o te pāmahana utu.
I tēnei wā, ko te ngaohiko putanga oNgā puranga utu DCKo te mea nui o te mākete ko te 400V, kāore e taea te utu tika i te pākahiko 800V, nō reira me whai hua DCDC tāpiri hei whakapiki i te ngaohiko 400V ki te 800V, kātahi ka utu i te pākahiko, e hiahia ana kia nui ake te mana me te whakawhiti auau-teitei, ā, ko te kōwae e whakamahi ana i te silicon carbide hei whakakapi i te IGBT tuku iho te whiringa matua o nāianei, ahakoa ka taea e ngā kōwae silicon carbide te whakanui ake i te mana putanga o ngā puranga utu me te whakaiti i ngā mate, engari he nui ake te utu, ā, he teitei ake hoki ngā whakaritenga mō te EMC.
Hei whakarāpopototanga. Ko te tikanga, me whakapiki ake te pikinga o te ngaohiko i te taumata pūnaha me te taumata taputapu, tae atu ki te pūnaha whakahaere wera, te pūnaha tiaki utu, me ētahi atu, ā, kei roto i te taumata taputapu te whakapainga o ētahi taputapu aukume me ngā taputapu hiko.
