Title: Ziva Musiyano UripoMiniature Circuit BreakersuyeMolded Case Circuit Breakers
Circuit breaker chikamu chakakosha chemagetsi echivako.Vanobatsira kuchengetedza imba yako, hofisi kana pfuma yekutengeserana kubva kumagetsi akawandisa uye mapfupi maseketi.Maviri anowanzo shandiswa mabreaker edunhu madiki madiki wedunhu (MCB) uye iyo molded case circuit breaker (MCCB)Kunyange zvazvo ose ari maviri achibatira chinangwa chimwe, pane misiyano yakati pakati pawo.Mune ino blog, tichaongorora kusiyana uku.
1. Kukura uye kushandiswa
Musiyano mukuru pakatiMCBuyeMCCBukuru hwavo.Sezvinoratidzwa nezita racho, maMCB madiki muhukuru uye anoshandiswa mune yakaderera ikozvino maapplication anosvika 125 amps.Ivo vanowanzoshandiswa mukugara uye zvidiki zvekutengesa zvikumbiro.MCCBs, kune rumwe rutivi, ihombe uye inokwanisa kubata yakakwira mitoro iripo kusvika ku5000 amps.Iwo anowanzo shandiswa mumaindasitiri uye ekutengesa maapplication anoda huwandu hwakanyanya hwesimba.
2. Yakasimba uye yakasimba
MCCB yakasimba uye yakasimba kudarika MCB.Vanogona kubata zvakanyanya kushushikana kwemagetsi uye zvakagadzirirwa kutsungirira nharaunda dzakaoma.MCCBskazhinji anogadzirwa nechinhu chakasimba senge ceramic kana purasitiki yakaumbwa kupfuuraMCBs, iyo inowanzogadzirwa neimba yepurasitiki.MaMCB akagadzirirwa kushandiswa munzvimbo dzine hukasha uye haafanire kuratidzwa kune zvinopisa zvakanyanya kana tembiricha yakanyanyisa.
3. Nzira yerwendo
Ose MCBs uyeMCCBsdzakagadzirirwa kuti dzifambe kana yazvino yadarika imwe muganhu.Zvisinei, nzira dzavanoshandisa kufamba dzakasiyana.Iyo MCB ine thermal magnetic trip mechanism.Iyo michina inoshandisa bimetal strip iyo inopisa uye inokotama kana ikozvino yadarika chikumbaridzo, zvichiita kuti muparadzi wedunhu afambe.Iyo MCCB ine yemagetsi rwendo michina inoshandisa microprocessor kuongorora kuyerera kwazvino.Kamwe ikozvino yadarika chikumbaridzo, iyo microprocessor inotumira chiratidzo kune wedunhu breaker kuti ifambe.
4. Mutengo
MCBskazhinji dzinodhura paneMCCBs.Izvi zvinodaro nekuti dzakareruka mukugadzira uye dzakagadzirwa nezvinhu zvakachipa.Iwo zvakare haana kusimba pane MCCBs uye ane yakaderera ikozvino kutakura kugona.MaMCCB anodhura zvakanyanya nekuda kwekugadzirwa kwawo kwakaoma uye zvinhu zvinoshandiswa, asi akasimba uye anogona kubata mitoro yepamusoro.
5. Kuchengeta
Kugadziriswa kunodiwa kune MCBs uyeMCCBsyakasiyana zvikuru.Iyo MCB iri nyore mukugadzira uye haidi zvakanyanya kugadzirisa.Dzinofanirwa kuongororwa nguva nenguva nenyanzvi yemagetsi uye dzotsiviwa kana dzakanganisa.MCCBs, kune rumwe rutivi, inoda kuchengetedzwa kwakawanda, sekuongororwa nguva dzose kwemagetsi ekufamba mayuniti, ayo anogona kusashanda nekufamba kwenguva uye anoda kutsiviwa.
Muchidimbu, MCB uyeMCCBvane basa rakafanana, rinova rekudzivirira hurongwa hwemagetsi kubva pakuremerwa uye pfupi pfupi.Zvisinei, sezvatinoona, pane zvimwe zvakasiyana pakati pezviviri izvi.MCBs idiki, yakasimba uye isingadhure, nepoMCCBsyakasimba, yakasimba uye inodhura.Kushandisa uye zvazvino zvinodiwa ndizvo zvinhu zvikuru zvekufunga nezvazvo pakusarudza pakati pezviviri.
