DC Yakawedzera Hondo Yemitengo: Kusagadzikana Kwemaindasitiri Nemisungo Yemhando Yepamusoro Zvaratidzwa

Gore rapera,Nzvimbo yekuchaja yeDC ye120kwasi zvakare 30,000 kusvika 40,000, gore rino, yakachekwa zvakananga kusvika 20,000, kune vagadziri vakadanidzira zvakananga 16,800, izvo zvinoita kuti munhu wese ade kuziva, mutengo uyu hautombodhurike, mugadziri uyu pakupedzisira maitiro ekuita. Kucheka makona kusvika pakukwirira kutsva here, kana kudzora mutengo kwakasimba chaizvo.

1. Chakavanzika che "mutengo wekabheji" ye16,800 yuan: mutengo uye purofiti yemusiyano unouraya
Zvichienderana neruzivo rweveruzhinji rweindasitiri, 120kW yakajairwapfuti mbiri DC yekuchaja murwimari huru, kusanganisiramodule yekuchaja(inenge 10,000 yuan), tambo yepfuti yemhando yepamusoro (3,000 yuan), motherboard (1,000 yuan) uye sheet metal, mafiyuzi nezvimwe zvikamu (zviuru zveyuan), mutengo wezvinhu zvese unosvika 1,000 yuan. ), mutengo wezvinhu zvese unosvika 17,000-19,000 RMB.

Kana mutengo wekutengesa we16,800 yuan ukaverengwa, bhizinesi harina chete purofiti, asi rinogona kutoita zvinhu zvisina kunaka. Pane mikana miviri yakavanzwa shure kweizvi:
- kuderedza zvikamu zvikuru: kushandisa mamodule emhando dzisiri dzemhando yepamusoro (dzakadai sedzimwe nzira dzepasi dzemuno), kana kuderedza huwandu hwemamodule (semuenzaniso, kugadzirisa mana chete20kW mamodule ekuchajanekuda kwekumhanya kwekuchaja);
- kuderedza magadzirirwo ekuchengetedza: kusashandisa AC contactor, kuderedza sisitimu yekupisa, kana kutoshandisa tambo isingadziviriri moto, zvichikonzera kukwira kwehuwandu hwekukundikana.

Nyaya yekuenzanisa
Murwi wekuchaja we120kW wemhando dzemusoro dzakadai sesimba reChina Beihaimutengo wayo uri pa25,000-30,000 RMB, ichitora mamodules makuru akadai seInfineon neYouYouGreen, uye ine dziviriro yekutarisa nekuchenjera uye kudzivirira overload seyakajairwa; imwe mhando ine mutengo wakaderera inoonekwa kuti inoshandisa mamodules akagadziriswazve akashandiswa, ane mwero wekukundikana wakakwira kusvika 27% (avhareji yeindasitiri iyi i8%-12%). Mamwe mabhizinesi ekuchaja mapoinzi, asi anochekawo makona, kwete kuisa mita yakasiyana, asi kushandiswa kwemita iri mubhodhi, kwete chete mutengo wakaderera, asiwo kunogona kugadziriswa kumita, kuitira kuti mapoinzi aya ashande pamwe chete nemushandi, asiwo anotyora zvido zvevatengi.

2. vanosimudzira hondo yemitengo: makwikwi ane hutsinye uye kusagadzikana kwemaindasitiri
1: kuwanda kwehuwandu hwevashandi uye kutonga kwemutemo:
Kurudziro yemutemo we "zvivakwa zvitsva" zvegore ra2020, kudzokororwa kwesimba rekugadzira zvinhu zvishoma, chikamu chebhizinesi kuitira kuwana rubatsiro rwekudzikisa mutengo wemakomba asina kunaka akazara mumusika; 2025 mwero mutsva wenyika usati watanga kushandiswa, vamwe vagadziri vanoda kubvisa zvinhu zviri muchitoro, vachirasikirwa nekurasikirwa nemari inoraswa.
2: "kuungana kwemiti" nzira yekuwedzera:
Vagadziri vadiki havana tekinoroji huru, vanovimba nekutenga zvinhu zvemhando yepamusoro, kubvisa R&D, kuyedza, kudzvanywa kwemitengo ye30% -40%; kambani ine mitengo yakaderera haina kupasa bvunzo yenyika yeEMC (electromagnetic compatibility), zvichikonzera kukanganiswa kwekuchaja nemidziyo yemagetsi yakapoteredza.
3: sarudzo yevashandi isina pfungwa dziri pedyo:
Vamwe vashandi vadiki nevepakati vanosarudza mapombi emhando yepamusoro anodhura zvishoma kuitira kuderedza mari yekutanga, asi kugadziriswa kwemari uye faindi (senge faindi dzegrid) zvinotungamira kumutengo wakakwana wemapombi ane mazita.

3. "Mukaha usingaoneki" pakati pemabhurendi makuru nemapoinzi ane mitengo yakaderera

Nyaya yakajairika: Shenzhen, nzvimbo yekuchaja inoshandisa murwi wemutengo wakaderera, avhareji yemari yekugadzirisa murwi mumwe chete pagore inodarika 5,000 yuan, nepo murwi wemhando iyi uri 800 yuan chete.

4. Yambiro yeindasitiri: dambudziko remari dzakaipa dzinodzinga mari dzakanaka
1 Njodzi yemushandisi:
- Kumhanya kwekuchaja hakusi kwechokwadi (simba chairo riri pasi pe100kW), zvichiita kuti nguva yekumirira yemushandisi iwedzere;
- Kuwedzera kwenjodzi dzemoto, murwi wemitengo yakaderera wakakonzera moto munzvimbo yekupaka mota nekuda kwekusapisa zvakanaka kwemoto.
2 Kukuvadzwa kwezvakatipoteredza muindasitiri:
- Mari inoshandiswa mukutsvaga nekuvandudza makambani makuru iri kuderedzwa, uye mari inoshandiswa mukutsvaga nekuvandudza makambani makuru eTeco ichadzikira ne15% gore negore muna 2024;
- Vashandi vanorasikirwa nekuda kwemakwikwi emitengo yakaderera, uye muripo webasa rekuchaja uchawedzera ne87% muQ1 2025, iyo ichapihwa kune vashandisi.

Kukwikwidza kwenyanzvi: Northern Polytechnic University yakaratidza kuti kudiwa kwekugadzira sisitimu ye "runyoro rwemhando yepamusoro", module brand, chitupa chekuchengetedza mumitemo yekutenga, kubvisa murwi wemhando isina kunaka mumusika.

5. Sarudzo ine musoro: kukosha kwenguva refu > mutengo wenguva pfupi
- Vashandi: vanofanirwa kuverenga mutengo wehupenyu hwese (LCC), murwi wemhando yemakore gumi mutengo wese wakaderera ne20% -30% pane murwi wemutengo wakaderera;
- Vashandisi: isa pamberi kusarudzayakashongedzwa netambo yepfuti inotonhorera mumvura, kuronga nekuchenjera webhusaiti hombe yekambani, kudzivirira njodzi yekukanganiswa kwekuchaja.

Mhedziso: Hondo yemitengo haingoburitse pachena kuvaka kwejecha rehunyanzvi chete, asiwo dambudziko guru rekushaikwa kwemitemo yeindasitiri. Nzira chete yekuita kutiChaja yemagetsiKudzokera kuindasitiri kune chinangwa chekuti "kuchengetedzwa ndiko mambo" kutora nzira ine zvikamu zvitatu kubva mumitemo yemitemo, kupihwa chitupa kwetekinoroji uye dzidzo yemusika.
Pakupedzisira, ndapota sarudzai michina yekuchaja, musangotarisa mutengo wakaderera chete, kuti muone kuti vanochengetedza mari kupi,vagadziri vemapombi ekuchajaVari kuitawo mari, michina ye120kw, mutengo wezvinhu wakaderera we17,000 kusvika 18,000 yuan kana zvakadaro, pamwe nepurofiti inonzwisisika ye20,000 ndiwo mutengo wakaderera, uye kana yakaderera pane isingawanzoitiki, vanogona kuchengetedza mutengo wenzvimbo isingafaniri kuva! Chengetedza mutengo panzvimbo iyoyo usingafaniri kuva.
