Miniature circuit breakers (MCBs) uye molded case circuit breakers (MCCBs) zvese zvakakosha midziyo mumasisitimu emagetsi anoshandiswa kudzivirira kubva pakuremerwa, mapfupi maseketi, uye kumwe kukanganisa. Kunyangwe chinangwa chakafanana, kuchine mimwe misiyano pakati pezviviri maererano necapacitance, hunhu hwekutsika, uye kutyora kugona.

Miniature Circuit Breaker (MCB)

A Miniature circuit breaker (MCB)chigadziriso chemagetsi chinoshandiswa kuchengetedza masekete kubva kumaseketi mapfupi uye kuwandisa. Inowanzoshandiswa mukugadzirwa kwemagetsi muzvivako zvekugara uye zvekutengeserana uye yakagadzirirwa kuchengetedza matunhu ega ega pane maitiro ose emagetsi.

Molded case circuit breaker (MCCB)

A Molded Case Circuit Breaker (MCCB)iguru, rakasimba redunhu rinotyora iro rinoshandiswawo kuchengetedza maseketi kubva kupfupi maseketi, kuwandisa, uye kumwe kukanganisa. MCCBs dzakagadzirirwa yakakwirira voltage uye ikozvino ratings yekutengeserana, maindasitiri uye makuru ekugara ekushandisa.

Musiyano Mukuru Pakati peMCCB neMCB

Chimiro:MCBs dzakasimba muhukuru kupfuura maMCCB. Iyo MCB ine bimetallic strip inokotama kana ikozvino yadarika imwe chikumbaridzo, ichikonzera MCB nekuvhura dunhu. Asi chimiro cheMCCB chakanyanya kuoma. Electromagnetic mechanism inoshandiswa kukonzeresa dunhu kana yazvino ichidarika imwe chikumbaridzo. Mukuwedzera, iyo MCCB ine thermal magnetic dziviriro yekudzivirira kubva kune yakawandisa uye mapfupi maseketi.

KugonaMCBs anowanzo shandiswa kudzika ikozvino uye voltage ratings muzvivakwa zvekugara uye zvekutengesa. Kazhinji kusvika ku1000V uye ine zviyero zviri pakati pe0.5A ne125A. MCCBs dzakagadzirirwa maindasitiri uye makuru ekutengesa maapplication uye anogona kubata macurrents kubva pagumi amps kusvika 2,500 amps.

Breaking Capacity:Kupwanya simba ndiko kuwanda kwehuwandu hwekukanganisa ikozvino muparadzi wedunhu anogona kutsika pasina kukuvadza. Kana ichienzaniswa neMCB, MCCB ine mukana wepamusoro wekupwanya. MCCBs inogona kukanganisa mafairi kusvika ku100 kA, nepo MCBs inokwanisa kukanganisa 10 kA kana zvishoma. Naizvozvo, iyo MCCB inonyanya kukodzera maapplication ane yakakwira yekutyora simba.

Tripping Characters:Kubatsira kweMCCB neMCB ndiyo inogadziriswa rwendo kurongedza. Iyo MCCB inobvumira kugadziridzwa kwega kwega kwerwendo rwazvino uye kunonoka kwenguva yekudzivirira kwakanyanya kwemagetsi masisitimu nemidziyo. Kusiyana neizvi, maMCB ane magadzirirwo erwendo akasarudzika uye anowanzo kugadzirwa kuti afambe pane yazvino kukosha.

Mutengo:MaMCCB anowanzo kudhura kupfuura MCBs nekuda kwehukuru hwawo, maitiro ekushanda, nezvimwewo. MCCBs inonyanya kuve nehukuru hwepamusoro uye zvigadziriso zverwendo zvinogadziriswa. MCBs kazhinji isarudzo yakaderera-yekudzivirira yekudzivirira madiki emagetsi masisitimu nemidziyo.

Mhedziso

Muchidimbu, MCCBs neMCBs vanoita basa rakakosha mukudzivirira maseketi kubva kumaseketi mapfupi, kuwandisa, uye kumwe kukanganisa mumagetsi masisitimu. Kunyange zvazvo mabasa kana zvinangwa zvezviviri zvakafanana, pachine misiyano mukushandiswa. MCCBs akanyatsokodzera mahombe emagetsi masisitimu ane zvakakwirira zvinodikanwa zvino, nepo MCBs inodhura-inoshanda uye inokodzera zvirinani kudzivirira madiki emagetsi masisitimu nemidziyo. Kuziva misiyano iyi kuchakubatsira iwe kusarudza iyo yakakodzera yedunhu breaker kune zvaunoda chaizvo uye kuona kuti yako magetsi system inoramba yakachengeteka uye inoshanda.
