Chiyambi
M'zaka zaposachedwapa, ukadaulo wochaja mwachangu wafalikira kwambiri m'zida monga magalimoto atsopano amphamvu, ma laputopu, ndi mafoni a m'manja, ndipo mphamvu yochaja imawonjezeka nthawi zonse. Panthawi yochaja, mavuto achitetezo monga kuchuluka kwa magetsi, kulumikizana kosakhazikika, ndi kutentha kwambiri kumatha kuchitika. Monga gawo lofunika kwambiri loteteza mu dongosolo lochaja,masiwichi ang'onoang'onokuonetsetsa kuti chitetezo chili bwino kudzera mu mphamvu zawo zoyambitsa komanso kuyankha mwachangu.
Mawonekedwe enieni a ma switch ang'onoang'ono poonetsetsa kuti chitetezo cha chaji chili bwino
Masiwichi ang'onoang'onoimagwira ntchito ngati mzere woyamba wodzitetezera pakuteteza chitetezo cha ma charger interfaces. Pakugwirizana pakati pa mfuti yochajira ndi doko la magalimoto atsopano amphamvu, ngati mawonekedwewo sakugwira ntchito mokwanira kapena atayika, angayambitse kukhudzana koyipa, kupanga ma arcs ndikuyambitsa ngozi zamoto. Ma micro switch opangidwira zochitika zochajira ali ndi njira zodziwira kuyenda bwino mkati. Pokhapokha ngati mawonekedwewo agwira ntchito mokwanira ndipo malo olumikizirana akukwaniritsa zofunikira za conduction yamagetsi apamwamba ndi pomwe amatumiza chizindikiro cha "power-on allowed" ku dongosolo lowongolera. Ngati pali kuchotsedwa kosayembekezereka kapena kusuntha kwa mawonekedwe panthawi yochajira, micro switch imatha kudula mphamvu mwachangu mkati mwa masekondi 0.1, kuchotsa chiopsezo cha ma arcs omwe amayambitsidwa ndi plugging yamoyo ndi kuchotsa ma plugs. Deta yoyesera kuchokera ku kampani ina yochajira ikuwonetsa kuti kuchuluka kwa kulephera kwachitetezo komwe kumachitika chifukwa cha kulumikizana kotayirira mu zida zochajira zomwe zili ndi ma micro switch kwatsika kuchoka pa 8% kufika pa 0.5%.
Muzochitika zochaja mwachangu,masiwichi ang'onoang'onoSewerani ngati "valavu yotetezera dera" popewa chiopsezo cha kuchuluka kwa magetsi. Mphamvu yolipirira mwachangu yomwe ikugwiritsidwa ntchito pano yapitirira 200W, ndipo mphamvu yolipirira mwachangu yamagalimoto atsopano imatha kufika pa 100A. Ngati pali dera lalifupi kapena katundu wosazolowereka mu dera, mphamvu yochulukirapo imatha kuyatsa zingwe kapena zida. Ma switch apadera ang'onoang'ono ochajira, kudzera mu kapangidwe kake kozindikira mphamvu yamagetsi, amayang'anira kusinthasintha kwa magetsi mu dera nthawi yeniyeni. Mphamvu yamagetsi ikadutsa malire achitetezo, ma switch contacts amalekanitsidwa nthawi yomweyo, ndikupanga chitetezo chawiri ndi chip yoyang'anira mphamvu kuti apewe moto woyambitsidwa ndi kuchuluka kwa magetsi. Poyerekeza ndi zida zodzitetezera zachikhalidwe, ma switch ang'onoang'ono ali ndi liwiro loyankha mwachangu komanso kukhazikika kwakukulu kwa ma trigger, zomwe zimaphimba bwino zochitika zadzidzidzi monga kuchuluka kwa magetsi nthawi yomweyo, kupereka chitetezo chokwanira ku dera lochajira.
Kutentha kwambiri komwe kumachitika panthawi yochaja ndi chinthu china chofunikira chomwe chimakhudza chitetezo. Pamene mafunde amphamvu akuyenda, mawonekedwe a chaji ndi mizere yake zimatentha mosalekeza. Ngati kutentha kupitirira malire otetezeka, kungayambitse kukalamba kwa insulation ndi kulephera kwa zigawo.Masiwichi ang'onoang'onoZipangizo zolipirira kutentha zakonzedwa bwino kuti zisamavutike ndi kutentha: zolumikizirazo zimapangidwa ndi siliva-nickel alloy, yomwe imatha kupirira kutentha mpaka 125°C, ndipo kukana kukokoloka kwa arc kwawonjezeka katatu; nyumbayo imapangidwa ndi zinthu zosatentha kwambiri komanso zosayaka moto, kuphatikiza kapangidwe kake kotsekedwa, komwe sikungoletsa kuwonongeka kwa magwiridwe antchito chifukwa cha kutentha kwambiri komanso kumalimbana ndi kukokoloka kwa fumbi lakunja ndi madzi oundana, kuonetsetsa kuti magwiridwe antchito ake ndi olimba m'malo otentha kwambiri komanso chinyezi chambiri. Wopanga zida zina zamafoni adati atapereka mitu yake yolipirira mwachangu ndi ma switch ang'onoang'ono osatentha, kuchuluka kwa malipoti olakwika m'malo otentha kwambiri kunachepa ndi 60%.
"Chinsinsi cha chitetezo cha kuyitanitsa ndi 'kupewa mavuto asanachitike.' Ngakhalemasiwichi ang'onoang'ono"Ndi zazing'ono, zimatha kuchepetsa zoopsa mwachangu pazifukwa zofunika kwambiri," adatero mkulu wa kampani yopanga ma micro switch am'nyumba. Pofuna kukwaniritsa zosowa zosiyanasiyana zoyatsira, kampaniyo yapanga zinthu zapadera zamagalimoto atsopano amphamvu, zamagetsi, ndi zida zoyatsira mafakitale, zomwe zimaphatikizapo zinthu monga IP67 yosalowa madzi komanso yosavunda fumbi, kupirira kwamphamvu kwamagetsi, komanso kukana kutentha kwambiri, kukwaniritsa miyezo yachitetezo ya zida zosiyanasiyana zoyatsira. Pakadali pano, zinthuzi zakhala zikugwiritsidwa ntchito kwambiri poyatsira zida zamitundu yosiyanasiyana monga BYD, Huawei, ndi GONGNIU, ndipo zalandiridwa pamsika.
Mapeto
Ndi chitukuko cha ukadaulo wochapira mwachangu kwambiri, mphamvu yochapira ikupita patsogolo kufika pa 1000W komanso milingo yokwera kwambiri, ndipo zofunikira pazida zotetezera chitetezo zikuchulukirachulukira. Akatswiri amakampani amati mtsogolomu, ma switch ang'onoang'ono adzasintha kwambiri kukhala "ang'onoang'ono, kuyankha mwachangu, komanso kupirira kwakukulu", pomwe akuphatikiza ntchito ziwiri zozindikira kutentha ndi mphamvu kuti akwaniritse kulosera mwachangu komanso kuteteza chitetezo cholondola cha chaja, kupereka chitsimikizo cholimba cha kufalikira kwa ukadaulo wochapira mwachangu kwambiri. "Chigawo chaching'ono" ichi chobisika m'zida zochapira chikutsimikizira magwiridwe antchito odalirika, ndikupangitsa chaja chilichonse kukhala chotetezeka komanso cholimbikitsa.
