MCCB: muganhu wekuparara kwedunhu pfupi wakayerwa

Pakusarudzamuputsi wedunhu wakaumbwa (MCCB) pamagetsi ako, unofanirwa kutarisisa zvinhu zvakakosha. Chimwe chezvinhu izvi kugona kwayo kuputsa magetsi kwenguva pfupi. Izvi zvakakosha pakuona kuchengetedzeka uye kuvimbika kwemasystem emagetsi, uye zvakakosha kunzwisisa kukosha kwawo pakusarudza MCCB.

Kukwanisa kuputsa magetsi kwenguva pfupi kunoreva huwandu hwepamusoro apo circuit breaker inogona kuputsa magetsi kwenguva pfupi pasi pemamiriro ezvinhu akatarwa. Izvi zvakakosha pakudzivirira masisitimu emagetsi kubva kumigumisiro inogona kukuvadza yezvikanganiso zvemaseti mapfupi. Mushure mekuita bvunzo yakatarwa, circuit breaker inofanira kukwanisa kuramba ichitakura magetsi ayo akatarwa pasi pemamiriro ezvinhu chero api zvawo. Izvi zvinoita kuti sisitimu yemagetsi irambe ichishanda kunyangwe paine kutadza kushanda kweseti mapfupi.

Pamusoro pekugona kuputsa circuit pfupi kwakarongwa, kugona kuputsa circuit pfupi kwakarongwa kwemuchina wekupwanya circuit wakaumbwa kunofanirawo kufungwa nezvawo. Izvi zvinoreva kugona kuputsa pasi pemamiriro akatarwa. Zvinofanira kucherechedzwa kuti muchina wekupwanya circuit unofanirwa kuramba uchitakura magetsi ayo akarongwa mushure mekutevera maitiro ekuyedza akatarwa. Hunhu uhwu hwakakosha pakuona kuvimbika kwenguva refu uye kuchengetedzeka kwemasisitimu emagetsi.

Zvakakosha kuziva kuti vagadziri vazhinji vemacircuit breaker emumba parizvino vanopa maplastic case circuit breaker ane mazinga akasiyana ekugona kupwanya ma short-circuit kune frame-level rated current. Izvi zvinobvumira vashandisi kusarudza circuit breaker inonyatsoenderana nezvavanoda uye zvavanoda. Pakusarudza molded case circuit breaker, zvakakosha kuve nechokwadi chekuti short-circuit breaker yakakwana kune short-circuit current inotarisirwa yetambo yemagetsi. Izvi zvinobvisa kudiwa kwekuwedzera zvinhu zveinishuwarenzi, izvo zvinogona kutungamira mukurasa zvisina basa.

Kukosha kwesimba rekutyora madhiraivha ekushanda rakarongwa kunogona kusiyana, madhiraivha mazhinji anopa kugona kubva pa25% kusvika 75% yesimba rekutyora madhiraivha ekupedzisira. Mamwe madhiraivha anopawo 100% yesimba rekutyora madhiraivha ekushanda rakarongwa. Zvakakosha kufunga nezvemhando idzi nokungwarira pakusarudza MCCB nekuti dzinokanganisa zvakananga kuvimbika uye mashandiro emagetsi.

Muchidimbu, kugona kuputsa macircuit mapfupi kwakatarwa chinhu chakakosha chinofanira kufungwa nezvacho pakusarudza MCCB yemagetsi ako. Nekunzwisisa kukosha kwechinhu ichi uye kukanganisa kwachinoita pakuchengetedzwa uye kuvimbika kwemasystem emagetsi, unogona kuita sarudzo ine ruzivo pakusarudza MCCB inonyatsoenderana nezvaunoda uye zvaunoda. Nekuda kwesarudzo dzakasiyana-siyana dziripo kubva kuvagadziri vemacircuit breaker emumba, zvakakosha kuti unyatsoongorora kugona kuputsa macircuit mapfupi kweMCCB dzakasiyana kuti uve nechokwadi chekuti unosarudza sarudzo inonyatsokodzera masisitimu ako emagetsi.
