Kazhinji, muviri wemunhu unogona kunzwa kukosha kwazvino kwekukurudzira kuri kuita 1 mA.Kana muviri wemunhu unopfuura 5 ~ 20mA, mamhasuru anozobatana uye anozununguka, kuitira kuti munhu arege kuparadzaniswa newaya.Chigadzirwa chekuvhundutsa kwemagetsi ikozvino uye nguva inotenderwa nenyika zhinji ndeye 30mA * S kupikisa kwemuviri wemunhu Kazhinji 1500 ohms ~ 300000 ohms, kukosha kwakajairika ndeye 1000 ohms ~ 5000 ohms, inokurudzirwa kukosha ndeye 1500 ohms.
Iyo yakachengeteka voltage kukosha inogona kuwanikwa kubva pane kuita kwemuviri wemunhu kune ikozvino uye kuramba kwemuviri wemunhu: yakachengeteka voltage kukosha munyika yedu inowanzo 12 ~ 50V.
Kumira voltage, kuvuza ikozvino uye kuchengetedzeka kwesimba EMI sefa:
Dzvinyiriro uye kuchengeteka
1. Kana iyo Cx capacitor iri mufirita yakaputsika, yakaenzana nepfupi pfupi ye AC grid, zvishoma zvichiita kuti michina irege kushanda;kana Cy capacitor yakaputsika,
Izvo zvakaenzana nekuwedzera magetsi eiyo AC magetsi grid kune casing yemidziyo, iyo inotyisidzira zvakananga kuchengetedzeka kwemunhu uye inokanganisa midziyo yese ine simbi casing senzvimbo yereferensi.
Kuchengetedzwa kwedunhu kana midziyo, kazhinji kunotungamira mukupiswa kwemamwe maseketi kana michina.
2. Mimwe yepasirese inoshingirira kuchengetedzeka mwero ndeiyi inotevera:
Germany VDE0565.2 High Voltage Test (AC) P, N kusvika E 1.5kV/50Hz 1 min
Switzerland SEV1055 High Voltage Test (AC) P, N kusvika E 2*Un+1.5kV/50Hz 1 min
US UL1283 High Voltage Test (AC) P, N kusvika E 1.0kV/60Hz 1 min
Germany VDE0565.2 High Voltage Test (DC) P kusvika kuN 4.3*Un 1 min
Switzerland SEV1055 High Voltage Test (DC) P kusvika kuN 4.3*Un 1 min
US UL1283 High Voltage Test (DC) P kusvika kuN 1.414kV 1 miniti
enzanisira:
(1) Chikonzero chekushandisa DC voltage muPN inomira voltage test ndechekuti iyo Cx huwandu hwakakura.Kana AC bvunzo ikashandiswa, huwandu hwazvino hunodiwa neinomira voltage tester
Iyo yakakura kwazvo, inokonzera vhoriyamu yakakura uye inodhura;dambudziko iri harisipo kana DC inoshandiswa.Asi kushandura iyo AC inoshanda voltage kuita yakaenzana DC inoshanda voltage
Semuenzaniso, iyo yakanyanya AC inoshanda voltage ndeye 250V (AC) = 250 * 2 * 1.414 = 707V (DC), saka iyo UL1283 chengetedzo yakatarwa ndeye.
1414V(DC)=707*2.
(2) Iyo yekumira yemagetsi bvunzo mamiriro mugwaro reiyo inozivikanwa pasi rese sefa nyanzvi fekitori:
Corcom Corporation (USA) P, N kusvika E: 2250V(DC) kweminiti imwe chete P kusvika N: 1450V(DC) kweminiti imwe
Schaffner (Switzerland) P, N kusvika E: 2000V(DC) kweminiti imwe chete P kusvika N: Kunze kwe
Dzimba mafirita inyanzvi vagadziri vanowanzo reva kuGerman VDE mirairo yekuchengetedza kana yeAmerican UL yekuchengetedza mitemo
Leakage ikozvino uye kuchengeteka
Iyo yakajairwa modhi capacitor Cy yechero yakajairwa sefa yedunhu ine imwe magumo yakagumiswa mune simbi kesi.Kubva pakuona kwevoltage division, iyo metal casing yefirita ine
1/2 yevoltage yakayerwa, saka kubva panzvimbo yekuchengetedza yekuona, iyo inodonha yezvino (leakage current) kubva pasefa kusvika pasi kuburikidza neCy inofanira kunge idiki sezvinobvira.
zvichaisa pangozi kuchengeteka kwomunhu.
Mitemo yekuchengetedza yekuvuza ikozvino mune dzimwe nyika huru dzemaindasitiri pasirese ndeaya anotevera:
Ongorora: 1. Iyo yekudonha ikozvino yakanangana neiyo grid voltage uye grid frequency.Iko kubuda kweiyo 400Hz grid sefa kasere kakapetwa kasere kune iyo 50Hz grid (kureva.
Mafirita anosangana nemirairo yekuchengetedza mumagetsi frequency emagetsi magridi anogona kunge asiri kusangana nemirairo yekuchengetedza mune yakakwirira frequency magetsi magridi)
2. Paunenge uchitarisa kubuda kwesefa, chiyero chekuyera chinopindirana nezviyero zvepasi rose chinofanira kushandiswa (sezvinoratidzwa mumufananidzo uri pasi apa).Pakuyera, simbi yesimbi haigoni
Grounded, inofanira kumiswa.
Vhara dhizaini yefirita kuvuza ikozvino bvunzo redunhu:
Applications
1: Midziyo yemumba - inomira bvunzo yevoltage yemafiriji:
Edza kutsungirira voltage pakati pechikamu chemagetsi uye pasi.Mamiriro ekuedzwa: AC1500V, 60s.Miedzo mhinduro: hapana kuparara uye flashover.Kudzivirirwa kwekuchengetedza: Mushandi anopfeka magurovhosi anodzivirira, bhenji rebasa rinoiswa neanodzivirira pads, uye chiridzwa chakadzikwa zvakanaka.Hunhu hweOperator: ita pre-basa kudzidziswa, hunyanzvi mukushandisa zviridzwa, uye anogona chaizvo kuona uye kubata nekutadza kwechiridzwa.
Zviridzwa zvingasarudzwa:RK2670/71/72/74 series, chirongwa-inodzorwa RK7100/RK9910/20 akatevedzana.
Zvinangwa zvekuedza
Ita kuti magetsi echiridzwa adzikwe zvakavimbika, uye edza kutsungirira voltage maitiro echigadzirwa.
Testing process
1.Batanidza iyo yakakwirira yemagetsi kubuda kwechiridzwa kune simba rekuisa terminal refiriji (LN yakabatana pamwe chete) kune grid simba chikamu.Nzvimbo yepasi (kudzoka) kwechiridzwa chakabatanidzwa kune chigadziko chepasi chefriji.
2. The preset alarm current inoiswa maererano nechiyero chemushandisi.Isa nguva kusvika kuma60s.
3. Tanga chiridzwa, gadzirisa magetsi kuti uratidze 1.5Kv, uye uverenge kukosha kwezvino.Munguva yekuyedza, chiridzwa hachina yakakwira-leakage alarm, zvichiratidza kuti inomira voltage yapfuura.Kana alarm ikaitika, chigadzirwa chinotongwa sechisina kukodzera.
Zvekungwaririra
Mushure mekunge bvunzo yapera, simba rechiridzwa rinofanira kudzimwa pamberi pechigadzirwa uye mutsara wekuyedza unogona kutorwa kuti udzivise kusashanda uye tsaona dzekuchengetedza.
2.Leakage ikozvino bvunzo yemidziyo yemumba-washing machine
Mamiriro ekuedzwa: Pahwaro hwe1.06 nguva dzemagetsi ekushanda, edza kukosha kwezvino kuvuza pakati pesimba rekupa uye ivhu rekudzivirira retiweki yekuyedza.Chinangwa chekuyedza:Kuti zvikamu zvesimbi zvakafumurwa zvecasing zvine magetsi asina kuchengetedzeka kana mudziyo wemagetsi urikuedzwa uchishanda.
Mhedzisiro yebvunzo: verenga iyo leakage yazvino kukosha, ingave inodarika kukosha kwakachengeteka, chiridzwa chinorira neruzha uye nechiedza.Chengetedzo Chekuchengetedza: Panguva yekuyedzwa, chiridzwa neDUT zvinogona kubhadhariswa, uye zvinorambidzwa zvachose kuibata nemaoko kudzivirira kuvhunduka kwemagetsi uye njodzi dzekuchengetedza.
Optional modhi:RK2675 series, RK9950series, maererano nesimba rechigadzirwa chakaedzwa.Iyo imwe-chikamu ndeyekusarudza kubva ku500VA-5000VA, uye iyo-nhatu-chikamuRK2675WT, iyo ine mabasa maviri ezvikamu zvitatu uye imwe-chikamu.
Matanho ekuedza:
1: Chiridzwa chinobatidzwa, uye magetsi anoiswa pasi zvakavimbika.
2: Batidza magetsi echiridzwa, hwindo rinoratidza chiridzwa richavhenekera.Dzvanya bhatani rekuyedza/preset, sarudza yazvino huwandu hwe2mA/20mA, gadzirisa iyo PRE-ADJ potentiometer, uye isa alarm ikozvino.Wobva wadzvanya preset/yedzo bhatani kuti uedze nyika.
3: Batanidza chigadzirwa chemagetsi chiri pasi pekuyedzwa nechiridzwa, tanga chiridzwa, mwenje wekuyedza wakabatidzwa, gadzirisa gadziriso yevoltage kuti iratidziro yemagetsi isangane nezvinodiwa zvekuyedzwa, uye mushure mekuverenga kukosha kwazvino, gadzirisa chiridzwa uye gadzirisa. voltage kusvika kushoma.
Ongorora: Panguva yekuyedzwa, usabate goko rechiridzwa uye DUT.
Yetatu: bvunzo dzekupikisa pasi
Mamiriro ekuedzwa: ikozvino 25A, kuramba isingasviki 100 miriyoni.Edzai on-resistance pakati pepasi pekuisa simba uye zvikamu zvesimbi zviri pachena zvekesi.
Zviridzwa zvingasarudzwa:RK2678XM series (ikozvino 30/32/70 ampere sarudzo),RK7305 akatevedzana chirongwa-chinodzorwa muchina,RK9930 series (ikozvino 30/40/60 ampere sarudzo), purogiramu-inodzorwa yakatevedzana ine PLC chiratidzo chinobuda, RS232, RS485 kutaurirana mabasa.
bvunzo matanho
1: Batanidza tambo yesimba yechiridzwa kuti uve nechokwadi chekuti chiridzwa chakadzikwa zvakavimbika.
2: Batidza simba uye preset muganho wepamusoro wearamu kuramba.
3: Batanidza tambo yekuyedza kune iyo terminal yepini yezviridzwa zvinoenderana neruvara uye ukobvu (waya gobvu yakabatana kune hombe positi, uye tambo yakatetepa yakabatana kune diki positi).
4: Zvikamu zvekuyedza zvakateerana pasi pechishandiso chiri pasi pekuyedzwa (waya yepasi yekupera kwesimba rekuisa) uye nzvimbo yekudzivirira yecasing (isina simbi zvikamu) kuve nechokwadi chekuti bvunzo inobatidzwa, zvikasadaro test current haigone kugadziriswa.
5: Tanga chiridzwa (tinya START kuti utange), chiedza chekuedza chiridzwa chiripo, gadzirisa ikozvino (purogiramu-inodzorwa yakatevedzana inoda kuiswa pakutanga) kune inodiwa kukosha kwekuedzwa, uye verenga kupikisa kukosha.
6: Kana muedzo ukakundikana, chiridzwa chichava ne-buzzer alarm (sound and light), uye purogiramu-inodzorwa yakatevedzana yemigumisiro yekuedza ichava nePASS, FAIL zviratidzo zvemwenje uye inzwi uye chiedza.
