Iyo yakaderera voltage disconnector inosara kuseri kweyakaderera voltage wedunhu breaker?

Pane maonero akadaro here kuti disconnector inzvimbo yakaderera, uye muchengeti wedunhu inzvimbo yepamusoro-soro, apo kushandiswa kunoshandiswa kunoshandiswa, muchengeti wedunhu anogona kushandiswa panzvimbo?Pfungwa iyi inokakavadzana, asi vanodimbura uye vanopwanya vedunhu vane yavo yekushandisa.

Low voltage circuit breaker ndeye mechanic switching appatus inogona kugadzira, kutakura, uye kutyora ikozvino pasi peyakajairwa mamiriro edunhu, uye inogona zvakare kugadzira, kutakura, uye kutyora chikanganiso chazvino kwenguva yakati pasi pemamiriro asina kujairika senge pfupi pfupi.Low voltage circuit breakers inogona kupatsanurwa kuita furemu yedunhu mabreaker (ACB), akaumbwa kesi circuit breakers (MCCB) uye micro circuit breakers (MCB).Iyo yakaderera voltage isolator switch ine basa re isolator uye switch.Chokutanga pane zvose, ine basa rekuzviparadzanisa nevamwe.Panguva imwecheteyo, inogona kubatanidzwa, kumira uye kuputsa mutoro ikozvino pasi pemamiriro ezvinhu.Kureva kuti, iyo isolator switch ine basa reese ari oga uye switch.

Basa rezvitsaura nderokubvisa magetsi emagetsi emagetsi kana midziyo yemagetsi.Panguva imwecheteyo, iwe unogona kuona iyo yakajeka yekubvisa poindi.Iyo isolator haigone kuchengetedza mutsara kana midziyo.Asi shanduko haifaniri kunge ine basa rekuzviparadzanisa, rine basa rekushandura uye kubvisa mutoro wezvino, unogona kumira imwe nguva yenguva pfupi yedunhu.Semuenzaniso, iyo semiconductor switch haigone kushandiswa seyakasarudzika, nekuti semiconductor switch yemagetsi midziyo yemagetsi haina kuparadzaniswa nenyama, inodarika zvinodikanwa zvekudonha ikozvino kweiyo isolator isingasviki 0.5mA, saka iyo semiconductor haifanirwe kushandiswa sechinhu. isolator.

Muchokwadi, kune akawanda maapplication eiyo isolator switch, asi mune dzimwe nzvimbo, kushandiswa kweiyo isolator switch kunotsiviwa neanotyora wedunhu, kunyanya munharaunda yehurumende, iyo isingakundikani chete kugadzira nekuvaka zvinoenderana nezvinodiwa zve. iyo yakatarwa, asiwo inowedzera mutengo weprojekiti.Mashandisirwo eiyo disconnecting switch ndeaya anotevera:

(1) Iyo yepamusoro huru yekugovera kabhineti inodzivirirwa nemagetsi edunhu kana fuse, uye iyo radiation-yemhando yemagetsi nzira inogamuchirwa kupinda mumba.Iko hakuna bazi riri pakati pemagetsi emagetsi.Iyo cable inlet switch kune yekugovera kabati inofanirwa kuve yega.

(2) Midziyo yekuparadzanisa inofanirwa kuiswa padunhu guru remagetsi maviri ekupinza mitsara yemagetsi maviri sosi yekucheka mudziyo, uye yakakosha yekuparadzanisa switch inofanira kushandiswa.

(3) ingave iyo yakaderera magetsi magetsi ekugovera kabati inoda kuiswa zvakasiyana inoda kuongororwa, kana yakaderera magetsi magetsi ekugovera kabati iri kabati yemadhirowa, haugone kumisa mudziyo wekuzviparadzanisa nevamwe, nekuti kabati yedhirowa inogona kunge iri dunhu. breaker uye zvimwe zvakazara kunze;Kana iyo low voltage kugovera kabhineti iri kabati yakagadziriswa, switch yekubvisa inofanirwa kuiswa kana yedunhu breaker ine basa rekuzvitsaura rinofanira kushandiswa.

(4) Yese inopinda mutsetse webhokisi rebazi bhokisi inofanirwa kutora yakakosha yekudimbura switch, uye yega yega dunhu rebazi rinofanira kutora fuse mhando yekubvisa switch kana MCCB ine yakazara yekuzviparadzanisa nevamwe.

Muchidimbu, kuitira kuti zvive nyore kugadzirisa, kuedza uye kugadzirisa mitsara yemagetsi kana midziyo yemagetsi, zvakakosha kuisa switch yekubvisa panzvimbo iyo iri nyore kushanda uye nyore kuona.
