ULinyang uqhuba ezahlukeneyoimitha yombaneiimvavanyo zokuqinisekisa ukuba umgangatho wemitha uyahlangabezana nemigangatho yamazwe ngamazwe.Siza kwazisa iimvavanyo zethu eziphambili ngolu hlobo lungezantsi:
1. Uvavanyo lweMpembelelo yeMozulu
Iimeko zomoya
QAPHELA 1 Eli solotyana lisekelwe kwi-IEC 60068-1: 2013, kodwa ngamaxabiso athathwe kwi-IEC 62052-11: 2003.
Uluhlu olusemgangathweni lweemeko ze-atmospheri yokwenza imilinganiselo kunye novavanyo
yiba ngolu hlobo lulandelayo:
a) iqondo lobushushu kwindawo: 15 °C ukuya 25 °C;
Kumazwe anemozulu eshushu, umenzi kunye nelebhu yovavanyo banokuvuma ukuyigcina
iqondo lobushushu eliphakathi kwe-20 °C ukuya kuma-30 °C.
b) ukufuma okuhambelana nama-45% ukuya kuma-75%;
c) uxinzelelo lwe-atmospheric lwe-86 kPa ukuya kwi-106 kPa.
d) Akusayi kubakho qabaka, mbethe, amanzi avuthuzayo, imvula, imitha yelanga njalo njalo.
Ukuba iiparameters eziza kulinganiswa zixhomekeke kubushushu, uxinzelelo kunye/okanye nokufuma kunye ne
umthetho wokuxhomekeka awaziwa, iimeko zasemoyeni zokwenza imilinganiselo
kwaye iimvavanyo ziya kuba ngolu hlobo lulandelayo:
e) iqondo lobushushu kwindawo: 23 °C ± 2 °C;
f) ukufuma okuhambelana nama-45% ukuya kuma-55%.
QAPHELA 2 Amaxabiso avela kwi-IEC 60068-1: 2013, 4.2, ukunyamezela okubanzi kwiqondo lokushisa kunye noluhlu olubanzi lokufuma.
Ubume bezixhobo
Ngokubanzi
QAPHELA Igatyana 4.3.2 lisekelwe kwi-IEC 61010-1: 2010, 4.3.2, iguqulwe ngokufanelekileyo kwimitha yokulinganisa.
Ngaphandle kokuba kuchazwe ngenye indlela, uvavanyo ngalunye luya kuqhutywa kwisixhobo esihlanganiselwe
ukusetyenziswa okuqhelekileyo, kwaye phantsi kweyona ndibaniselwano incinci ilungileyo yemiqathango enikwe kwi-4.3.2.2 ukuya
4.3.2.10.Kwimeko yokuthandabuza, uvavanyo luya kwenziwa ngaphezu kwendibaniselwano enye
Iimeko
Ukukwazi ukwenza ezinye iimvavanyo, njengokuvavanya kwimeko yempazamo enye, ukuqinisekiswa kwe
ukucocwa kunye nemigama ye-creepage ngokulinganisa, ukubeka i-thermocouples, ukujonga
i-corrosion, umzekelo olungiselelwe ngokukodwa unokufuneka kwaye / okanye kunokuba yimfuneko ukusika
umboniso ovalwe ngokusisigxina uvulelwe ukuqinisekisa iziphumo
A. Uvavanyo lobushushu obuphezulu
Ukupakisha: akukho ukupakisha, uvavanyo kwimeko engasebenziyo.
Ubushushu bovavanyo: Ubushushu bovavanyo yi +70 ℃, kwaye uluhlu lonyamezelo yi ±2℃.
Ixesha lovavanyo: iiyure ezingama-72.
Iindlela zokuvavanya: Itheyibhile yesampula ifakwe kwibhokisi yokuvavanya ubushushu obuphezulu, ifudunyezwe ukuya ku-+70 ℃ ngesantya esingekho ngaphezulu kwe-1℃/min, igcinwe iiyure ezingama-72 emva kokuzinziswa, kwaye emva koko ipholile kwiqondo lobushushu lereferensi ngesantya esingekho sikhulu. kune-1℃/min.Emva koko, ukubonakala kwemitha kuhlolwe kwaye impazamo esisiseko yavavanywa.
Ukumiselwa kweziphumo zovavanyo: emva kovavanyo, akufanele kubekho umonakalo okanye utshintsho lolwazi kwaye imitha inokusebenza ngokuchanekileyo.
