Linyang anoita zvakasiyanamita yemagetsibvunzo dzekuona kuti mhando yemamita inosangana nezviyero zvepasi rose.Isu ticha suma yedu huru bvunzo sezviri pazasi:
1. Muedzo weKupesvedzera Kwemamiriro ekunze
Atmospheric mamiriro
CHERECHEDZA 1 Ichi chidimbu chinobva paIEC 60068-1:2013, asi ine tsika dzakatorwa kubva kuIEC 62052-11:2003.
Iyo yakajairwa huwandu hwemamiriro emuchadenga ekuita zviyero uye bvunzo inofanira
kuita sezvinotevera:
a) ambient tembiricha: 15 °C kusvika 25 °C;
Munyika dzine mamiriro ekunze anopisa, mugadziri nerabhoritari yebvunzo vangabvumirana kuchengeta
tembiricha iri pakati pe20 °C kusvika 30 °C.
b) hunyoro hunyoro 45% kusvika 75%;
c) kumanikidzwa kwemhepo ye86 kPa kusvika 106 kPa.
d) Hapana chando chechando, dova, mvura inoputika, mvura, mwaranzi yezuva, nezvimwe zvichavepo.
Kana maparameter achayerwa anoenderana netembiricha, kudzvanywa uye/kana humidity uye
mutemo wekutsamira hauzivikanwi, mamiriro emuchadenga ekuita zviyero
uye bvunzo dzichava sezvinotevera:
e) ambient tembiricha: 23 °C ± 2 °C;
f) hunyoro hunyoro 45% kusvika 55%.
CHERECHEDZA 2 Izvo zvakakosha zvinobva kuIEC 60068-1: 2013, 4.2, kushivirira kwakakura kwekushisa uye kwakakura kwehunyoro.
Mamiriro emidziyo
General
CHERECHEDZA Chikamu 4.3.2 chakavakirwa paIEC 61010-1: 2010, 4.3.2, yakagadziridzwa seyakakodzera kuyera.
Kunze kwekunge zvatsanangurwa neimwe nzira, bvunzo yega yega ichaitwa pamidziyo yakaunganidzirwa
kushandiswa kwakajairika, uye pasi pemusanganiswa wakanyanya kunaka wemamiriro akapihwa mu4.3.2.2 kusvika
4.3.2.10.Kana paine kusahadzika, bvunzo dzichaitwa mune inodarika imwe musanganiswa we
Conditions
Kuti ukwanise kuita mamwe bvunzo, sekuyedza mune imwechete kukanganisa mamiriro, ongororo ye
clearances uye creepage distances nekuyera, kuisa thermocouples, kutarisa
corrosion, muenzaniso wakagadzirirwa unogona kudiwa uye / kana zvingave zvakakosha kucheka
mufananidzo wakavharwa zvachose wakavhurika kuti uone zvawanikwa
A. High Temperature Test
Kurongedza: hapana kurongedza, bvunzo mune isiri-kushanda mamiriro.
Tembiricha yekuyedza: Tembiricha yekuyedza ndeye +70 ℃, uye iyo yekushivirira huwandu ndeye ± 2 ℃.
Nguva yekuedza: 72 maawa.
Nzira dzekuyedza: Tafura yekuenzanisira yakaiswa mubhokisi rekuyedza tembiricha yakakwira, yakapiswa kusvika +70 ℃ pamwero usiri mukuru kupfuura 1 ℃/min, yakachengetedzwa kwemaawa makumi manomwe nemaviri mushure mekudzikamiswa, uye yozotonhodzwa kune tembiricha yereferensi pamwero usiri mukuru. kupfuura 1℃/min.Zvadaro, kutaridzika kwemamita kwakatariswa uye kukanganisa kwekutanga kwakaedzwa.
Kutsunga kwemhedzisiro yebvunzo: mushure mebvunzo, hapafanirwe kuve nekukuvadzwa kana shanduko yeruzivo uye mita inogona kushanda nemazvo.
B. Low Temperature Test
Kurongedza: hapana kurongedza, bvunzo mune isiri-kushanda mamiriro.
Test tembiricha
-25±3 ℃ (mukati magetsi mita), -40±3℃ (kunze magetsi mita).
Kuedza nguva:Maawa 72 (indoor wattmeter), maawa gumi nematanhatu (wattmeter yekunze).
Nzira dzekuyedza: Mamita emagetsi ari pasi pekuyedzwa akaiswa mukamuri yekuyedza yakaderera-tembiricha.Zvinoenderana nemhando yemukati / yekunze yemamita emagetsi, iwo akatonhodzwa kusvika -25 ℃ kana -40 ℃ pamwero usiri mukuru kupfuura 1 ℃/min.Mushure mekudzikamisa, ivo vakachengetwa kwemaawa makumi manomwe nemaviri kana gumi nematanhatu, vozokwidziridzwa kune tembiricha yereferensi pamwero usiri mukuru kupfuura 1 ℃/min.
Kutsunga kwemhedzisiro yebvunzo: mushure mebvunzo, hapafanirwe kuve nekukuvadzwa kana shanduko yeruzivo uye mita inogona kushanda nemazvo.
C. Damp Heat Cyclic Test
Kurongedza: hapana kurongedza.
Mamiriro: Voltage dunhu uye dunhu rekubatsira rakavhurika kune referensi voltage, yazvino dunhu rakavhurika
Imwe nzira: Nzira 1
Yedza tembiricha:+40±2℃ (wattmeter yemukati), +55±2℃ (wattmeter yekunze).
Nguva yekuedza: 6 cycles (1 kutenderera 24 maawa).
Nzira yekuyedza: Iyo mita yemagetsi yakaedzwa inoiswa mune inochinjika humidity uye kupisa bvunzo bhokisi, uye tembiricha nehunyoro zvinogadziridzwa otomatiki zvichienderana neinotsinhanisa humidity uye kupisa kutenderera dhizaini.Mushure memazuva matanhatu, tembiricha uye humidity room yakadzoserwa kune referensi tembiricha uye hunyoro uye yakamira kwemaawa makumi maviri nemana.Zvadaro, kutaridzika kwemamita emagetsi kwakatariswa uye bvunzo yesimba rekudzivirira uye yekutanga kukanganisa bvunzo yakaitwa.
Mhedzisiro yemuyedzo inoratidza kuti kuvharwa kwemamita emagetsi emagetsi hakufanirwe kuputswa (iyo pulse voltage ndeye 0.8 nguva dzeiyo amplitude yakatarwa), uye mita yemagetsi yemagetsi haina kukuvara kana shanduko yeruzivo uye inogona kushanda nemazvo.
D. Kudzivirirwa Kurwisana neKupisa kweSolar
Kurongedza: hapana kurongedza, hapana mamiriro ekushanda.
Tembiricha yekuyedza: Tembiricha yekumusoro yekumusoro i +55 ℃.
Nguva yekuedza: 3 cycles (3 mazuva).
Maitirwo ekuedza: Nguva yekuvhenekera imaawa masere, uye nguva yekudzima i16 maawa ekutenderera kumwe chete (iyo radiation intensity ndeye 1.120kW/m2±10%).
Nzira yekuyedza: Isa mita yemagetsi pabhuraketi woipatsanura kubva kune mamwe mamita emagetsi kudzivirira kuvharira kwaibva mwaranzi kana kupisa kwechipiri.Inofanirwa kuiswa pasi pemwaranzi muchiedza chezuva chekuyedza bhokisi kwemazuva matatu.Munguva yeirradiation, tembiricha iri mukamuri yekuyedza inokwira uye inoramba iri padanho repamusoro tembiricha +55 ℃ pamwero uri padyo nemutsara.Munguva yekumira kwechiedza, tembiricha iri mukamuri yekuyedza inodonha kusvika +25 ℃ pamwero ungangoita mutsara, uye tembiricha inoramba yakatsiga.Mushure mekuedzwa, ita ongororo yekuona.
Chigumisiro chekuedza chinoratidza kuti kuonekwa kwemamita emagetsi, kunyanya kujekesa kwechiratidzo, hakufaniri kuchinja zviri pachena, uye kuratidzwa kunofanira kushanda zvakanaka.
2. Kudzivirirwa Muedzo
Midziyo yekuyera ichaenderana nedanho rinotevera redziviriro rinopihwa mukati

CHERECHEDZA 2 Mamita akashongedzerwa nemuviri ekubhadhara tokeni vatakuri vanogamuchira ndeyekushandisa mukati memba chete, kunze kwekunge
neimwe nzira inotsanangurwa nemugadziri.
• mita yekunze: IP54.
Kune mapaneru akaiswa mamita, uko mapaneru anopa IP dziviriro, iyo IP ratings inoshanda kune iyo
mita zvikamu zvakafumurwa pamberi (kunze) kwegetsi remagetsi.
CHERECHEDZA 3 Meter zvikamu kuseri kwepanera zvinogona kunge zvine yakaderera IP chiyero, semuenzaniso IP30.
A: Dust proof test
Chiyero chekudzivirira: IP5X.
Jecha uye guruva rinoputika, kureva kuti, guruva harigoni kudzivirirwa zvachose kupinda, asi kuwanda kweguruva kunopinda hakufaniri kukanganisa kushanda kwemamita emagetsi, hakufaniri kukanganisa kuchengetedza.
Zvinodiwa zvejecha neguruva: talc yakaoma inogona kusefa kuburikidza neskweya gomba sieve ine dhayamita 75 m uye waya dhayamita makumi mashanu.Hupfu hwehupfu i2kg/m3.Kuti uone kuti guruva rekuedza rinowira zvakaenzana uye zvishoma nezvishoma pamamita emagetsi ekuedza, asi kukosha kwepamusoro hakufaniri kudarika 2m / s.
Mamiriro ekunze mukamuri yekuyedza: tembiricha mukamuri iri +15 ℃~+35 ℃, uye hunyoro hune 45% ~ 75%.
Nzira yekuyedza: Iyo mita yemagetsi iri munzvimbo isingashande (hapana pasuru, hapana magetsi), yakabatana netambo yakafananidzirwa yehurefu hwakakwana, yakavharwa nechivharo chechivharo, yakaturikwa pamadziro akafananidzirwa eguruva proof test mudziyo, uye inotakurwa. kunze jecha uye guruva kuvhuvhuta bvunzo, nguva yekuyedza maawa masere.Huwandu hwehuwandu hwewatt-awa metres haifanire kudarika 1/3 yenzvimbo inoshanda yebhokisi rekuyedza, nzvimbo yepasi haifanire kudarika 1/2 yenzvimbo inoshanda yakatwasuka, uye chinhambwe chiri pakati pebvunzo watt-awa metres uye. rusvingo rwemukati rwebhokisi rekuedza harifaniri kuva pasi pe100mm.
Mhedzisiro yebvunzo: Mushure mebvunzo, huwandu hweguruva hunopinda muwatt-awa mita haifanire kukanganisa basa rewatt-awa mita, uye kuitisa insulation simba bvunzo pawatt-awa mita.
