He aha te Kaiwhati Porowhita DC?

A Kohikohiko DC he taputapu whakamarumaru motuhake i hangaia hei aukati i nga iahiko o naianei (DC) i raro i te taumahatanga, te ara-poto, me nga tikanga he. Kaore i te rite ki nga wehenga ara iahiko AC e whai hua ana mai i nga whakawhiti kore-kore o naianei (100-120 nga wa ia hekona i te 50/60Hz), me whakaweto kaha nga kaiwahi DChaere tonu, arc unidirectional karekau he taonga tinei i a ia ano. Ko tenei rereketanga nui e hiahia ana ki nga hangarau tiini pewa, kia nui ake, kia uaua ake, kia nui ake te utu atu i o raatau AC.

Ka mahi nga kaiwahi iahiko DC puta noa i nga awhe ngaohiko mai12V ki te 1500V DC, me nga whakatauranga o naianei e hora ana2A ki te 2500A. Ka noho hei waahanga whakamarumaru nui i roto i nga punaha photovoltaic solar (PV), nga punaha rokiroki hiko hiko (BESS), waka hiko (EV) te utu infrastru.te waahi, nga pokapū raraunga me te tohatoha hiko DC, nga mana whakahaere motuka DC ahumahi, me nga punaha hiko moana.

Ko te wero matua mo te aukati DC kei rotoarc extinction ahupūngao: Ko nga arcs DC e pupuri ana i nga pou plasma pumau me te pāmahana neke atu i te 10,000°C, me whakaroa te kaha, te whakamatao, me te whakakorenga iraona ma roto i nga papa aukume, nga arc chute, me nga taonga whakapiri motuhake.

Nga Mahi Matua me te Kaupapa Whakahaere

Ko te wero DC Arc

Kaore i rite ki nga pewa AC ka tineia noa i nga whakawhiti-kore o naianei, ko nga pewa DC he wero whakamomori ahurei:

Tawhā	AC Arc	DC Arc
Te ahua ngaru o naianei	Sinusoidal, kore-whakawhitinga ia 10ms (50Hz)	Tonu, rahi tonu
Ngaohiko pewa	Rereke ana me te au	Stable, me mate kaha
Te ngaronga arc	Maori me te kore-whakawhiti	Ko te whakaroa kaha me te whakamatao
Pūngao Arc	He pupuhi, he iti te toharite	Tonu, wera kukū
Whakapaa kakahu	Whakaōrite	He kino kaore he tine tika
Aputa e hiahiatia ana	Iti ake	2-3× rahi ake mo te ngaohiko rite

Hangarau Whakamutua Arc

Hangarau	Hangaia	Taupānga	Mahi
Putanga aukume	Ko te kaha o Lorentz F = I × L × B ka peia te pewa ki roto i nga papa wehewehe i te 50-200 m/s	Ao mo DC MCB/MCCB	Ko te nuinga noa, te utu-utu, 10-20kA pakaru
Arc Chute me nga Pereti Ritua	Kua wehea te pewa ki nga waahanga raupapa, whakamataohia, whakahekehia	Paerewa i roto i nga wehenga DC katoa	Waenga tino nui, te heke ngaohiko mo ia pereti 30-50V
Aukume Tuturu	NdFeB aukume (0.1-0.3T) hāngai ki te ara pewa	MCB DC kiato	Karekau he hiko o waho, te pāmahana-u ki te 150°C
Poipoi Putanga Hiko	Ko te kowiri whakakaha-whaiaro ka whakaputa mara e rite ana ki te he o naianei	Nga MCCB teitei o naianei	Ka piki ake te kaha me te whakamarumaru o naianei
Pokarekaretanga	Ka tineia te pewa i roto i te korehau (kaore he reo katote)	DC ngaohiko teitei, motuhake	He pai mo> 1000V DC, he roa te ora, he utu nui
Putanga Hau	Ka whakamatao te hau kōpeke, ka totoro te pewa	Te ahumahi mana nui, tuku iho	He nui te tiaki, he uaua ki te whakamahi i nga hoahoa hou

Ahukume Putanga Aukume

Ko te whārite kaha Lorentz e whakahaere ana i te raweke arc DC:

F = I × L × B

Kei hea:

F = Te kaha ki te pewa (Newtons)

I = Awa pewa (Amperes)

L = Roa Pewa (mita)

B = kiato rere aukume (Tesla)

Tauira Tataunga:

Arc nāianei: 1000A

Roa Pewa: 0.02m (2cm)

Papa aukume: 0.2T

Te kaha: F = 1000 × 0.02 × 0.2 = 4N

Whakaterenga: a = 4N / (5×10⁻⁴ kg/m × 0.02m) = 400,000 m/s²

Ko tenei whakaterenga nui ka peia te pewa ki roto i nga pereti wehewehe i roto i nga manomano, ka wehea, ka whakamatao, ka tineia.
