Musoro: Ziva Musiyano PakatiMadiki eDunhu reMaputsiuyeMakadhi eDunhu Akaumbwa Akavhurika
Macircuit breaker chikamu chakakosha chemagetsi echivako. Anobatsira kuchengetedza imba yako, hofisi kana zvivakwa zvebhizinesi kubva pakuzara kwemagetsi uye mashort circuit breaker. Macircuit breaker maviri anoshandiswa zvakanyanya ndiwo maminiature circuit breaker (MCB) uye chinopwanya dunhu chekesi chakaumbwa (MCCBKunyangwe zvese izvi zvichishanda nechinangwa chimwe chete, pane musiyano pakati pazvo. Mublog rino, tichaongorora musiyano uyu.
1. Saizi uye mashandisirwo
Musiyano mukuru uripo pakati peMCBuyeMCCBsaizi yadzo ndeye. Sezvinoratidzwa nezita racho, maMCB madiki uye anoshandiswa mumashandisirwo emagetsi mashoma anosvika 125 amps. Anowanzo shandiswa mumashandisirwo emagetsi ekugara uye madiki ekutengeserana. MCCB, kune rumwe rutivi, dzakakura uye dzinogona kutakura mitoro yemagetsi yakakwira inosvika 5000 amps. Anowanzo shandiswa mumashandisirwo emaindasitiri neekutengeserana anoda simba rakawanda.
2. Yakasimba uye inogara kwenguva refu
MCCB yakasimba uye inogara kwenguva refu kupfuura MCB. Inogona kutsungirira kumanikidzwa kwemagetsi kwakanyanya uye yakagadzirirwa kutsungirira mamiriro ekunze akaomarara.MCCBsdzinowanzogadzirwa nezvinhu zvakasimba zvakaita seceramic kana molded plastic kupfuuraMCBs, izvo zvinowanzogadzirwa nepurasitiki. MCB dzakagadzirirwa kushandiswa munzvimbo dzisina kuomarara uye hadzifanirwe kuiswa panjodzi huru kana kupisa kwakanyanya.
3. Nzira yekufamba nayo
MCBs uyeMCCBsZvakagadzirirwa kudonha kana magetsi adarika muganho wakati. Zvisinei, nzira dzavanoshandisa kudonha dzakasiyana. MCB ine nzira yekufamba nemagetsi inodziya. Nzira iyi inoshandisa bimetal strip inopisa uye inokotama kana magetsi adarika muganho, zvichiita kuti circuit breaker iwire. MCCB ine nzira yekufamba nemagetsi inoshandisa microprocessor kuongorora kuyerera kwemagetsi. Kana magetsi adarika muganho, microprocessor inotumira chiratidzo kune circuit breaker kuti iwire.
4. Mutengo
MCBskazhinji zvinodhura zvishoma paneMCCBsIzvi zvinodaro nekuti dzakareruka pakugadzirwa uye dzakagadzirwa nezvinhu zvakachipa. Hadzina kusimba zvakanyanya pane MCCB uye dzine simba shoma rekutakura magetsi. MCCB dzinodhura zvakanyanya nekuda kwekugadzirwa kwadzo kwakaoma uye zvinhu zvinoshandiswa, asi dzakasimba uye dzinogona kutakura magetsi akawanda.
5. Kugadzirisa
Kugadziriswa kunodiwa kune MCBs uyeMCCBsyakasiyana zvikuru. MCB iri nyore kugadzira uye haidi kugadziriswa kwakawanda. Inofanira kuongororwa nguva nenguva nenyanzvi yemagetsi uye inotsiviwa kana isina kunaka. MCCB, kune rumwe rutivi, inoda kugadziriswa kwakawanda, senge kuongororwa nguva dzose kwemayuniti emagetsi, ayo anogona kusashanda nekufamba kwenguva uye anoda kutsiviwa.
Muchidimbu, MCB naMCCBane basa rimwe chete, iro rekudzivirira sisitimu yemagetsi kubva pakuzara kwemagetsi uye kupfupika kwemagetsi. Zvisinei, sezvatinoona, pane musiyano pakati pezviviri izvi. MaMCB madiki, anogara kwenguva refu uye asingadhuri zvakanyanya, nepoMCCBsdzakasimba, dzinogara kwenguva refu uye dzinodhura. Mashandisirwo adzo uye zvinodiwa pari zvino ndizvo zvinhu zvikuru zvekufunga nezvazvo pakusarudza pakati pezviviri izvi.
