Iyo Yakakosha Basa reJCR2-125 Residual Current Devices (RCDs) muElec

It nekuda kweichi chikonzero kuchengetedzwa kwemagetsi kwave kune chikamu chikuru chave mutasvi wekutanga munyika inogara ichishanduka yehunyanzvi. Maseketi emagetsi anogona kubatsira zvakanyanya kune zvinangwa zvakasiyana munharaunda asi zvakare anouya nenjodzi dzakasiyana siyana dzinogona kuitika kana dzisina kubatwa zvakanaka. Iri ndiro basa rinoitwa nevaResidual Current Devices (RCDs)uye Residual Current Circuit Breakers (RCCBs). Izvi zvakagadzirirwa kuchengetedza vanhu uye midziyo kubva kune njodzi dzemagetsi nekucheka dunhu nekukurumidza kana chikamu chisina kunaka kana kuvuza ikozvino kuripo. Mumwe muenzaniso wemudziyo wakadaro ndeyeJCR2-125 RCD, iyo yakagadzirwa nemaune uye yakagadziridzwa kuderedza mukana wekugamuchira kutyisa kwemagetsi kunouraya uye kuderedza njodzi dzine chokuita nemoto wemagetsi.

Kunzwisisa JCR2-125 RCD

Iyo JCR2-125 RCD chishandiso chemagetsi chine hunyanzvi hwepamusoro sezvo basa rayo guru nderekutarisa kubuda kwemvura kudzivirira vashandisi. Kana paine kuvuza ikozvino zvinoreva kuti chimwe chikamu cheyedzo ikozvino chiri kukonzera ikozvino kuburikidza nenzira isingatarisirwe senge kuburikidza nemuviri kana kuparara kwekudzivirira. Iyo JCR2-125 yakanyatso gadzirwa kuti ifambe kubva mudunhu mune zviitiko zvakadaro senzira yekudzivirira kubva pakukuvadzwa kwakaipa kana kurasikirwa.

Iwo makuru maficha eiyo itsva JCR2-125 RCD wedunhu breaker anotsanangurwa seizvi:

Iyo JCR2-125 RCD inouya iine akati wandei akakosha maficha anoita kuti ishande zvakanyanya uye yakavimbika mukuona kuchengetedzwa kwemagetsi: Iyo JCR2-125 RCD inouya iine akati wandei akakosha maficha anoita kuti ishande zvakanyanya uye yakavimbika mukuona kuchengetedza kwemagetsi:

Electromagnetic Type:Iyo zvakare inova nechokwadi chekuti kune nekukurumidza uye kwakaringana kutyora kubva kudunhu kana kubuda kwemvura kwaonekwa.

Earth Leakage Protection:Inoderedza njodzi kubva mukukanganisa kwemagetsi izvo zvinogona kukonzera kurohwa nemagetsi kana moto.

High Breaking Capacity:Iyo ine simba rekutyora kusvika ku6kA, izvo zvinoita kuti ikwanise kukanganisa kwete chete kuburikidza neyakajairwa ikozvino asiwo yakakura kukanganisa ikozvino panguva imwe chete pasina kukuvara.

Multiple Rated Currents:Inowanikwa muzviyero zvakasiyana se25 amps, 32 amps, 40 amps, 63 amps, 80 amps, uye 100 amps inoiisa munzvimbo yekutarisira kushandiswa kwakasiyana.

Tripping Sensitivity:Zvitatu zvinobuda zvinoti 30mA, 100mA, uye 300mA kusangana nedziviriro inodiwa yekuyerera inobuda mumidziyo.

Kutevedza Zviyero:Inoenderana nezvinodiwa zvekuvimbika uye kuchengetedzeka kweIEC 61008-1 uye EN61008-1.

Positive Status Indication Contact:Zvinokwanisika kushandisa zvakajeka uye zviri nyore-ku-kuzivikanwa zviratidzo zvinoonekwa zvine chokuita nekushanda kwechigadzirwa.

Installation Flexibility:Inogona kumiswa kune 35mm DIN njanji uye ine mukana wekubatanidzwa kumusoro kana pasi, zvichiita kuti zvive nyore kuisa.

Robust Design:Iine mechanical end-use hupenyu hwe2000 nguva uye magetsi ekupedzisira-kushandisa hupenyu hwe2000 nguva, nekuda kwezvose chikamu uye inobatsira hupenyu hwekushanda.

Mukutsvaga uku, kune maRCD akasiyana, uye pazasi pane marudzi eRCD nemashandisirwo awo.

Mhando dzakasiyana dzekusara ikozvino dzinoshandiswa kuisa RCDs zvichienderana nekunzwa kwavo. Iyo JCR2-125 inopa ese Type AC uye Type A RCDs, imwe neimwe inokodzera kune chaiwo maapplication: Iyo JCR2-125 inopa ese ari maviri Type AC uye Type A RCDs, imwe neimwe inokodzera kune chaiwo maapplication:

Nyora AC RCDs

Pakupedzisira, rega mhando AC RCDs ione iyo sinusoidal yakasara inotsinhanisa ikozvino. Izvi zvinowanzowanikwa mukushandiswa kwepamba kuchengetedza midziyo inopikisa, capacitive, kana inductive pasina kushandisa chero magetsi. Ivo vanodzivirira kubva ku-swing uye nekupa nekukurumidza counter-steer nekukurumidza kana kusaenzana kunoonekwa.

Nyora A RCDs

Nepo Type A RCDs inogona kuziva sinusoidal residual ikozvino pamwe nekusara pulsating yakananga ikozvino idiki se6mA yezvino pa AC frequency. Izvi zvinoita kuti dzive dzakakodzera kushandiswa uko midziyo yemagetsi inobatanidzwa kunyanya mumagetsi akaomarara edunhu sezvo vachipa dziviriro iri nani mumasisitimu akadaro kana zvichienzaniswa nemamwe marudzi ekupikisa.

Kukosha Kwekufamba Sensitivity

RCD tripping senitivity inoreva kugona kweRCD kupindura kune chikanganiso chakakonzera maitiro ekutanga, mukati meimwe nguva. Iyo JCR2-125 inopa mazinga matatu ekunzwa: Iyo JCR2-125 inopa matatu mazinga ekunzwa:

30mA: Inobvuma mamwe matanho ekuchengetedza kubva pakubata zvakananga nezvikamu zvipenyu, izvo zvakare zvinoita kuti mudziyo uve wakanaka kune wega chengetedzo.

100mA: Yakabatana neyepasi system kudzivirira kutyisidzira kweasina kunanga kubata system uye kuderedza njodzi ine chekuita nemoto wemagetsi.

300mA: Inopa dziviriro kubva pakubata kwechipiri uye inonyanya kubatsira mukudzivirira kubva kumoto unokonzerwa nenyaya dzemagetsi.

Zvinyorwa zvehunyanzvi zveJCR2-125

Iyo tekinoroji yeJCR2-125 yakarongedzerwa kuve nechokwadi chekushanda kwakakwana uye kuchengetedzeka mumashandisirwo akasiyana-siyana: Iyo tekinoroji yakatarwa yeJCR2-125 yakarongedzwa kuti ive nechokwadi chekuita kwakanyanya uye kuchengetedzeka mumashandisirwo akasiyana siyana:

Yakatemerwa Yazvino: Inogona kuwanikwa muhukuru hwakadzika se25A uye kusvika ku100A yakakwira amperage mune yezita razvino renji.

Yakarongerwa Kushanda Voltage: Inoyera 110V, 230V, uye 240V yezvakasiyana zvinodiwa sedunhu kana maererano nedunhu rinodiwa.

Yakatemerwa Sensitivity: Ivo vanouya mumhando dzemazuva ano se30mA, 100mA, uye 300mA kuti ikwane rudzi rwekudzivirira runodiwa.

Kutyora Kugona: Kukanganisa ikozvino kutyora kusvika ku6kA kunogona kuve kuburikidza nemuchinjiko-chikamu.

Insulation Voltage: 500V resistor ine insulation yakakodzera maererano neVCR rating tsika.

Yakatemerwa Frequency: Haisi kungoshandiswa kune 50/60Hz maapplication.

Impulse Withstand Voltage: Iyo ine simba rekutsungirira kusvika ku6kV, iyo inobatsira zvikuru kana paine kukwira kwemagetsi.

Dziviriro Dhigirii: Haina kutaurwa zita uye isina kusimba kwazvo ine IP yekudzivirira chiyero che20 chete zvinoreva kuti inongodzivirira kubva kune zvimedu zvezvakaoma uye guruva.

Ambient Temperature: Inogona kushanda pasi petembiricha ye -5 madhigirii centigrade kukwira kusvika patembiricha ye40 madhigirii centigrade saka inogona panharaunda.

Bata Position Indicator: Inopa chiratidzo chakajeka chechimiro chechishandiso, kureva, ON kana kwete nekuvhenekera kana kupenya tsvuku tsvuku yemagetsi mwenje, zvichiteerana nepo girinhi iri yekuratidza iyo yekumira.

Mukupedzisa, Iyo JCR2-125 RCD sechinhu chekutanga chinoshandiswa mumasisitimu ekuchengetedza anhasi mukuisa magetsi. Zvinonyanya kubatsira mukukwanisa kwayo kukurumidza kupatsanura maseketi ane mafambiro ari kubuda anokonzeresa njodzi yekubatwa nemagetsi uye kunyangwe njodzi dzemoto. Nekuda kwekushanda kwakawanda kweJCR2-125, senge akasiyana akayerwa maya, kukwirira kutyora simba, uye kutevedzera mwero wepasirese, inopa dziviriro inoshanda kune dzekugara, mabhizinesi, uye mafekitori.

Naizvozvo, zvakasiyana-siyana categorizationsRCDsuye kuona misiyano pakati pavo kwakakosha kuita kuti munhu aone iyo inonyanya kushanda mudziyo weimwe mamiriro ezvinhu. Ngaive iyo Type AC yezvido zvemazuva ese kana Type A yenzvimbo dzinoda mwero wedziviriro, iyo JCR2-125 haina kunaka kwete chete kuchengetedza chivakwa chako asiwo nekupa chengetedzo kune vashandisi vayo. Saka, kutora zviridzwa zvakadaro zvinofambira mberi zvinobvumira kuderedza kutyisidzira kuri kubuda kubva kumagetsi emagetsi uye kugadzirisa mararamiro nemamiriro ekushanda.
