Nguva pfupi yadarika International Electrotechnical Commission EE yakabvumidza, kuburitsa nekukanzura akati wandei CTL resolution pamabhatiri, ayo anonyanya kusanganisira inotakurika bhatiri certification standard IEC 62133-2, simba rekuchengetedza bhatiri chitupa chiyero IEC 62619 uye IEC 63056.

IEC 62133:2017, IEC 62133:2017 +AMD1:2021:kanzura bhatiri 60Vdc muganho voltage inodiwa

Muna Zvita 2022, CTL yakapa chisungo chekuti voltage yezvigadzirwa zvebhatiri paki haigone kudarika 60Vdc. Iko hakuna chirevo chakajeka nezve voltage muganho muIEC 62133-2, asi inoreva iyo IEC 61960-3 yakajairwa.

Chikonzero chakaita kuti chigadziriso ichi chikanzurwe neCTL ​​ndechekuti "yepamusoro magetsi e60Vdc acharambidza zvimwe zvigadzirwa zvemaindasitiri kubva mukuedzwa kwakajairika, senge maturusi emagetsi, nezvimwe."

IEC 62133:2017, IEC 62133:2017 +AMD1:2021:kanzura tembiricha yekuchaja inoshanda zvinodiwa

Saizvozvovo, muchisarudzo chenguva pfupi chakapihwa muna Zvita gore rapfuura, zvakarongwa kuti pakuchaja nenzira yeChikamu 7.1.2 (inoda kubhadharisa pamatembiricha epamusoro uye epasi), kunyangwe muAppendix A.4 yechiyero chainoti. kuti kana tembiricha yekuchaja yepamusoro / yepasi isiri 10 ℃/45 ℃, tembiricha yekuchaja inotarisirwa inofanirwa kunge iri +5 ℃ uye yakaderera. kuchaja tembiricha inoda kusvika -5 ℃. Nekudaro, panguva yekuyedzwa chaiko, iyo +/- 5 ° C mashandiro anogona kusiiwa uye kuchaja kunogona kuitwa zvinoenderana neyakajairwa yepamusoro / yakaderera muganho wekuchaja tembiricha.

Chisungo ichi chakapasiswa pamusangano weCTL wegore rino.

IEC 62619: 2017: shandisa yechitatu-bato yakagadziridzwa BMS yekuongorora kuchengetedza pane bhatiri basa.

Ichi chigadziriso chiri pamusoro pekuchengetedzeka kuongororwa kwebhatiri BMS masisitimu basa.

Iye zvino vazhinji vanogadzira mabhatiri vanotenga BMS kubva kune vechitatu mapato, izvo zvingaite kuti mugadziri webhatiri atadze kunzwisisa yakadzama BMS dhizaini. Kana mumiriri wekuyedza achiitisa ongororo yekuchengetedza kuburikidza neAnnex H yeIEC 60730-1, mugadziri haakwanise kupa iyo sosi kodhi yeBMS.

Muchiitiko ichi, mumiriri wekuyedza anogona kuongorora iyo kodhi kodhi yakazvimiririra nemugadziri weBMS kuchengetedza kodzero dzayo dzepfuma. Iko kushanda kwekuchengetedza ongororo yebhatiri system kwakakosha, uye ongororo haigone kudzimwa nekuda kwekuti mugadziri webhatiri haakwanise kupa iyo kodhi kodhi.

Parizvino, chigadziriso ichi chichiri chenguva pfupi uye chichatenderwa pamusangano weCTL muna 2024.(PDSH 2230)

IEC 63056: 2020: insulation resistance test voltage

IEC 63056: 2020 Chikamu 7.4 (Electric insulation inspection panguva yekufambisa uye kuiswa) inoreva IEC 62133: 2017 yekuyedza kuramba. Uku kukanganisa kugadzirisa. Chirevo chinofanira kunge chiri IEC 62133-2: 2017. Kukanganisa uku kwakaziviswa kuIEC TC21A.

IEC 63056 yakajairwa inogona kuvhara zvigadzirwa nemhepo yakakura ye1500Vdc, asi iyo test voltage yeIEC 62133-2:2017 insulation resistance test ndeye 500Vdc. Kana iyo yakanyanya voltage yebhatiri system inodarika 500Vdc, ndeipi voltage yekuyedza inofanira kushandiswa?

Insulation kuramba bvunzo ichiri kushandisa IEC 62133-2: 2017 5.2 yekuongorora. Waya uye kuvharirwa kunofanirwa kukwana kumirisana neiyo yakanyanya inotarisirwa voltage uye kuongororwa zvinoenderana nezvinodiwa zveIEC 60950-1: 2005, 3.1 uye 3.2 (tarisa IEC 63056: 2020 clause 5.2).

Tarisa kumufananidzo uri pazasi, paunenge uchiita insulation resistance test, pane nzira mbiri dzekubatanidza iyo insulation resistance tester. Kana mudziyo wekuyedza uye sampuli yekuyedza zvakabatana munhevedzano, iwo ma voltages anove akakwidziridzwa, uye kumwe kuvharirwa kwebhatiri system kunogona kumira bvunzo voltage kupfuura chiyero. Kuteedzera bvunzo kunofanirwa kuitwa panguva ino here?

Series yekubatanidza iyo inogona kukonzera voltage superposition haina kukodzera. Chikonzero chemusiyano uyu ndechekuti chinangwa cheIEC 63056: 2020 ndechekuyera "kupokana kwekudzivirira kweDC kudhumhana uye system inodzivirira conductor mikana". Chinangwa cheIEC 62133-2: 2017 kuyera "kupokana kwekudzivirira pakati peiyo yakanaka terminal yebhatiri uye yekunze yakashama simbi yepasi (kusingabatanidze magetsi ekubata kumeso). Parizvino, chisungo ichi chichiri chigadziriso chechinguvana uye chichabvumidzwa pamusangano weCTL muna 2024.(PDSH 2229)
