CB-Type ATS: Sarudzo Yakangwara Uye Yakachengeteka yeMasisitimu Emagetsi Emazuva Ano

Mumasisitimu emagetsi, otomatiki switch (ATS) chishandiso chakakosha chinovimbisa kupa simba nguva dzose kune zvinhu zvakakosha. Pakati peizvi, iyo CB-rated ATS yave kushandiswa zvakanyanya muzvivakwa zvemabhizinesi nenzvimbo dzemaindasitiri nekuda kwekugadzirwa kwayo kwakasiyana uye hunhu hwayo hwekushanda. Chinyorwa chino chichaongorora mabhenefiti makuru eCB-rated ATS kubva pazvikamu zvitatu: kuchengetedzeka, kushanda zvakanaka kwemari, uye kuchinjika kwekushandisa.

I. Mabasa Ekudzivirira Akabatanidzwa Anovandudza Kuchengetedzeka Kwesisitimu

(1) Dziviriro mbiri kubva kumaseketi mapfupi uye kuwanda kwezvinhu

ATS ine chiyero cheCB inosanganisira mudziyo wekufamba nemhepo unogara uchitarisa magetsi emuchadenga. Munguva yepfupi, main contacts anogona kukanganisa magetsi emuchadenga mukati memamiliseconds, kudzivirira kupisa kwemidziyo kana njodzi dzemoto. Semuenzaniso, munzvimbo yekutengeserana, ATS yegiredhi reCB yakabudirira kumisa dambudziko remuchadenga mubhokisi rekugovera, ichidzivirira kupararira kwemoto. Dziviriro yayo yekupfuura mwero, inowanikwa kuburikidza nemidziyo yekufamba nemhepo inopisa, inokonzeresa otomatiki kunonoka kwerwendo kana magetsi emuchadenga adarika kukosha kwakarongwa, ichidzivirira michina uku ichidzivirira kukanganiswa kwenhema.

(2) Kupatsanurwa Kwezvikanganiso uye Kugoverwa Kwemagetsi Kunogara Kwakaringana

Kusiyana nePC-grade ATS, CB-grade ATS inoita mabasa ekudzivirira nekufambisa kuburikidza nemudziyo mumwe chete. Mumamiriro ezvinhu emagetsi ekugara, kana simba rekutanga rikakundikana, CB-grade ATS inokurumidza kubvisa dunhu risina kunaka uye inoshandura kune backup power source mukati memasekondi 1-2. Dhizaini iyi inobvisa kuoma kwekuda mamwe macircuit breakers pakushandisa PC-grade ATS, zvichideredza njodzi dzesystem dzinokonzerwa nekusashanda zvakanaka kwemidziyo yekudzivirira. Semuenzaniso,YUYE'S CB Automatic Transfer SwitchYEQ3-63W1inosangana zvizere nezvinodiwa izvi. YEQ3-63W1Switch yeAutomatic Transfer yakakodzera AC 50Hz/60Hz, ine voltage yekushanda iri pasi pe230V/400V uye pasi pesimba rekugovera nekudzora magetsi. Chiyero chemazuva ano chinosvika ku63A. Chinonyanya kushanda sechishandiso chikuru chemidziyo yemagetsi yeterminal uye chinogonawo kudzora mhando dzakasiyana dzemota, midziyo yemagetsi ine simba shoma, mwenje, nezvimwe zvinoshandiswa.

Inoenderana nezvinodiwa zveGB/T14048.11 uye IEC947-6-1.

II. Zvakanakira Mari Yehupenyu Hwako

(1) Mari Yekutanga Yekutenga Nekugadzirisa Yakaenzana

Kunyangwe mayuniti eATS ane CB anodhura zvishoma ne30%-50% payuniti imwe neimwe pane ePC-rated, mari yese yehupenyu hwawo inoda kuongororwa kwakazara. Mune imwe purojekiti yepaki yemaindasitiri, mari yekugadzirisa yemakore gumi (kusanganisira calibration yeyuniti yerwendo uye kutsiva contact) yeATS ine CB-rated yaive 65% chete yemhinduro ine CB-rated. Kunyange hazvo dhizaini yayo yezvivakwa iine 50% yakawanda yezvikamu zvinofamba kupfuura mayuniti ane PC-rated, dhizaini yemodular inoderedza kuoma kwekugadzirisa kamwe chete, ichideredza mari yevashandi ne40%. (2) Kudyara Kwakagadziriswa Kwekushandisa Mamiriro Ezvinhu Kuchinjika

CB-grade ATS inoratidza zvakanakira zvehupfumi zvakanyanya mune zvisinganyanyi kukosha zvakaita semwenje yekutengeserana. Mushure mekushandisa CB-grade ATS, nzvimbo yekutengesa yakaderedza mwero wealamu yenhema ne82% munguva dzekupisa dzinoshandiswa zvakanyanya, zvichidzivirira kurasikirwa kwekudzima kwemagetsi kunokonzerwa nekudzivirira overload isina kushandiswa zvakanaka. Kurongeka kwayo kwakarurama kwehunhu hwekudzivirira ne load profiles kunopfupisa nguva yekubhadhara mari kusvika pasi pemakore matatu.

III. Kuchinjika kweMashandisirwo Kunosangana Nezvinodiwa Zvakasiyana-siyana

(1) Kuchinjika Kwakasimba kuMagadzirirwo Emagetsi

ATS ine CB-rated inogona kushanda zvakananga sema feeder switches muma radial power supply systems pasina kushandisa mimwe michina yekudzivirira. Muma trunk-type architectures, kusarudza kubatana nema downstream circuit breakers kunoita kuti fault locate isvike padanho re branch circuit. Semuenzaniso, mushure mekushandisa CB-rated ATS, chemical plant yakaderedza three-level load load incident ne70%, zvichiwedzera zvakanyanya kuvimbika kwesystem.

(2) Kuvimbisa Kutevedzera Mutemo

Zvichienderana neGB51348-2019 itsva, zvinhu zvinodzivirira moto zvinoda ATS ine mabasa ekudzivirira ma "short-circuit" uye alarm overload. ATS ine CB-rated ATS inosangana zvakakwana nezvinodiwa zve "overload alarm chete" zvemapombi emoto nezvimwe zvakafanana nekugadzira ma "trip units" asingakanganisi alarm chete. Chirongwa chechipatara chakashandisa mhinduro iyi chakaona kuvandudzwa kwe50% mukushanda kwekuongorora moto.

Pfupiso

Kuburikidza nekugadzirwa kwekudzivirira kwakabatana, mari yakagadziriswa yehupenyu, uye kuchinjika kwekushandisa, CB-rated ATS inopa mhinduro yemagetsi isingadhuri yezvivakwa zvemabhizinesi, zvivakwa zvemaindasitiri, nezvimwe zvakafanana. Kushanda kwayo kwakaringana kwekuchengetedza uye kushanda kwayo zvakanaka kunoita kuti ive sarudzo inosarudzwa kune masisitimu emagetsi asingakoshi. Nekuvandudzwa kwegridi yakangwara, kugona kwekudzivirira kwedhijitari kweCB-rated ATS kuchawedzera miganhu yekushandisa kwayo.
