Hunhu uye Kushandiswa kweMolded Case Circuit Breaker MCCB

MCCB Yakaumbwa Nyaya yeDunhu RemafunguChinhu Chinokosha MuMasisitimu Emagetsi

Munyaya dzeinjiniya yemagetsi uye kugoverwa kwemagetsi, ma "molded case circuit breakers" (MCCBs) anoita basa guru mukuona kuchengetedzeka uye kuvimbika. Akagadzirirwa kuchengetedza ma "circuit" kubva pakuwanda kwemagetsi uye ma "short circuit", zvishandiso izvi zvinhu zvakakosha mukushandiswa kwedzimba nemaindasitiri. Kunzwisisa mashandiro, mabhenefiti, uye mashandisirwo e "MCCBs" kunogona kubatsira vashandisi kuita sarudzo dzine ruzivo maererano nekuchengetedzeka kwemagetsi uye kushanda zvakanaka.

Chii chinonzi MCCB?

Chinopwanya dunhu chemagetsi chakaumbwa (MCCB) chishandiso chemagetsi chinongomisa kufamba kwemagetsi kana paine dambudziko rakadai sekunge circuit overload kana short circuit. "Chinopwanya dunhu" zvinoreva imba inodzivirira inochengeta zvikamu zvemukati zvechinopwanya dunhu, izvo zvinowanzogadzirwa nezvinhu zvinodzivirira. Dhizaini iyi haingowedzere kugara kwenguva refu chete, asiwo inodzivirira kusangana netsaona nezvikamu zvipenyu, nokudaro ichivandudza kuchengetedzeka.

Ma "molded case circuit breakers" (MCCBs) anowanikwa mumhando dzakasiyana-siyana dze "current ratings", kazhinji kubva pa16A kusvika 2500A, kuti akwane mashandisirwo akasiyana-siyana. Ane michina ye "thermal" uye "magnetic trip" yekubata mamiriro akasiyana-siyana e "fault". Ma "thermal trips" anobata overloads kwenguva refu, nepo "magnetic trips" ichipindura nekukurumidza kuma "short circuit", zvichiita kuti "circuit break" ikurumidze kudzivirira kukuvara.

Mabhenefiti eMCCB

1. Kudzivirira overload uye short circuit: Basa guru re molded case circuit breaker (MCCB) nderekudzivirira circuit kubva mukukuvadzwa kwe overcurrent. Nekubvisa circuit kana paine chikanganiso, MCCB inobatsira kudzivirira kutadza kwemidziyo uye njodzi dzinogona kuitika pamoto.

2. Magadzirirwo anogadziriswa: Mazhinji macase circuit breakers ane magadzirirwo anogadziriswa ekufamba, zvichibvumira vashandisi kugadzirisa mwero wekudzivirira zvinoenderana nezvinodiwa zvemagetsi avo. Kuchinjika uku kunobatsira zvikuru munzvimbo dzemaindasitiri uko mamiriro emutoro anogona kusiyana.

3. Dhizaini diki: Makesi ekupwanya mabhokisi akagadzirwa anoshandisa dhizaini yekesi yakaumbwa ine nzvimbo diki, zvichiita kuti akwanise kuiswa munzvimbo dzisina nzvimbo yakawanda. Chimiro chawo chakasimba chinoitawo kuti agare kwenguva refu uye avimbike munzvimbo dzakaoma.

4. Zviri nyore kuchengetedza uye kugadzirisa patsva: Kusiyana nemafuse echinyakare anoda kutsiviwa mushure mekukanganisa, Molded Case Circuit Breaker (MCCB) inogona kugadziriswa patsva nyore nyore mushure mekunge kukanganisa kwabviswa. Chinhu ichi hachingochengetedzi nguva chete asiwo chinoderedza nguva yekusashanda.

5. Mabasa akabatanidzwa: Mazhinji ema "case circuit breakers" emazuva ano ane mamwe mabasa, akadai sekuyera kwakavakirwa mukati, mabasa ekutaurirana, uye mabasa ekudzivirira epamusoro. Mabasa aya anovandudza kutarisa nekutarisira masisitimu emagetsi, zvichibatsira kuvandudza kushanda zvakanaka uye kuchengetedzeka.

Kushandiswa kweMCCB

Molded case circuit breakers inoshandiswa zvakanyanya muminda yakasiyana-siyana, kusanganisira:

- Zvivako zveMaindasitiri: Mumafekitori ekugadzira, maMCCB anodzivirira michina nemidziyo kubva kumatambudziko emagetsi, zvichiita kuti ishande zvakanaka uye inoderedza nguva yekushanda.

- Zvivako zveMabhizimisi: Muzvivako zvemahofisi nenzvimbo dzekutengesa, maMCCB anodzivirira masisitimu emagetsi, achipa dziviriro yakavimbika yemwenje, masisitimu eHVAC, nezvimwe zvivakwa zvakakosha.

- Kuisa Dzimba: Varidzi vedzimba vanogona kubatsirwa neMCCB mupaneru yavo yemagetsi kuti vape kuchengetedzeka kwakawedzerwa kwemidziyo yemumba nemasisitimu.

- Masisitimu Esimba Rinodzokororwa: Nekuwedzera kwekuisa simba rezuva nemhepo, maMCCB ari kushandiswa zvakanyanya kudzivirira ma inverter nezvimwe zvikamu kubva kumatambudziko emagetsi.

Muchidimbu

Ma "molded case circuit breakers" (MCCBs) zvishandiso zvakakosha mumagetsi emazuva ano, zvichipa simba rakawanda rekudzivirira mafambiro emagetsi uye ma "short circuit". Kushandiswa kwavo kwakasiyana-siyana, nyore kushandisa, uye maficha epamusoro zvinoita kuti ive sarudzo yepamusoro yekushandiswa kwakasiyana-siyana. Sezvo masisitimu emagetsi achiramba achichinja, michina yekudzivirira yakavimbika seMCCBs ichawedzera kukosha, ichivimbisa kuchengetedzeka uye kushanda zvakanaka munyika yedu ine magetsi akawanda.
