Kuongororwa kweMabasa neMashandisirwo eDC MCB

KunzwisisaDC MCB: Gwaro Rakazara

Izwi rekuti "DC miniature circuit breaker" (DC MCB) riri kuramba richinyanya kutaurwa muminda yeinjiniya yemagetsi uye kugoverwa kwemagetsi. Sezvo kudiwa kwemasisitimu emagetsi anoshanda uye akavimbika kuri kuramba kuchikura, kunzwisisa basa nemashandiro emaDC miniature circuit breakers kwakakosha kune nyanzvi nevanofarira zvakafanana.

Chii chinonzi DC MCB?

DC miniature circuit breaker (MCB) mudziyo unodzivirira unodzima circuit yega kana paine overload kana short circuit. Kusiyana neAC miniature circuit breakers, dzakagadzirirwa AC systems, DC miniature circuit breakers dzakagadzirirwa zvakananga maDC applications. Musiyano uyu wakakosha nekuti maitiro aripo muDC systems akasiyana zvikuru neari muAC systems, kunyanya maererano ne arc extinction and fault current characteristics.

Kukosha kweDC Miniature Circuit Breakers

Kukosha kwemaDC miniature circuit breakers hakufanirwe kutaurwa zvakanyanya, kunyanya mumashandisirwo ayo magetsi eDC aripo. Mashandisirwo aya anosanganisira masisitimu esimba rinogona kushandiswazve senge solar photovoltaic (PV) installations, bhatiri emagetsi, uye mota dzemagetsi. Mumamiriro ezvinhu aya, kuvimbika uye kuchengetedzeka kwemagetsi ndizvo zvinonyanya kukosha, zvichiita kuti basa reDC miniature circuit breakers rive rakakosha.

1. Dziviriro Yekuwedzeredza: MaDC miniature circuit breakers (MCBs) anoshandiswa kudzivirira macircuit kubva pakuwedzeredza. Kana magetsi adarika simba recircuit, MCB inodonha, zvichidzivirira kukuvara kwewaya nemidziyo yakabatana.

2. Dziviriro ye "short-circuit": Kana "short circuit" ikaitika, ma "DC miniature circuit breakers" (MCBs) anokurumidza kubvisa "circuit", zvichideredza njodzi yemoto nekukuvara kwemidziyo. Kukurumidza uku kwakakosha pakuchengetedza kuchengetedzeka kwemagetsi.

3. Dhizaini isingakuvadzi: Mazhinji maDC miniature circuit breakers akagadzirwa kuti ave nyore kuisa nekushandisa. Anowanzo kuve ne switch iri nyore yekugadzirisa nemaoko mushure mekugumburwa, zvichiita kuti zvive nyore kune nyanzvi nevanofarira DIY kushandisa.

Zvinhu zvikuru zveDC miniature circuit breakers

Pakusarudza DC miniature circuit breaker, zvinhu zvakakosha zvinofanirwa kutariswa:

Rated Current: DC miniature circuit breakers (MCBs) inowanikwa mumhando dzakasiyana dze rated currents, zvichibvumira vashandisi kusarudza mudziyo wakakodzera zvichienderana nezvinodiwa zvavo. Kusarudza rated current miniature circuit breaker kwakakosha pakuona dziviriro yakakwana.

- Rated Voltage: Voltage yakayerwa yeDC MCB inoratidza voltage yakanyanya yainogona kutsungirira. Zvakakosha kusarudza MCB inoenderana nevoltage yesystem kudzivirira zvikanganiso.

- Hunhu Hwerwendo: Ma "miniature circuit breakers" akasiyana ane hunhu hwakasiyana hwerwendo, izvo zvinosarudza kuti anokurumidza sei kupindura kune overloads uye short circuits. Kunzwisisa hunhu uhwu kwakakosha pakuona kuchengetedzeka uye kuvimbika kwemasystem emagetsi.

- Kugadzika Kwemapango: MaDC MCB anowanikwa muhurongwa hwemapango rimwe chete, mapango maviri, uye mapango akawanda, zvichienderana nehuwandu hwemaseketi avanoda kuchengetedza. Sarudzo yehugadzikano inoenderana nekushandiswa kwacho uye dhizaini yesystem.

Kushandiswa kweDC Miniature Circuit Breakers

MaDC miniature circuit breakers ane mashandisirwo akasiyana-siyana, anosanganisira:

- Sisitimu yekugadzira magetsi ezuva: Mukuisa magetsi ezuva, maDC MCB anodzivirira waya nezvikamu kubva pakuzara kwemagetsi uye mapfupi, zvichiita kuti sisitimu igare yakachengeteka uye ichishanda zvakanaka.

- Masisitimu Ekuchengetera Mabhatiri: Sezvo dzimba nemabhizinesi akawanda achishandisa nzira dzekuchengetera mabhatiri, maDC MCB anoita basa rakakosha mukudzivirira masisitimu aya kubva kumatambudziko emagetsi.

- Mota dzeMagetsi: Mumota dzemagetsi, maDC MCB akakosha pakudzivirira mabhatiri nemagetsi, zvichibatsira kuona kuchengetedzeka kwemota.

Muchidimbu

Zvichitaurwa zviri nyore, maDC miniature circuit breakers (MCBs) zvinhu zvakakosha mumagetsi emazuva ano eDC. Kugona kwawo kudzivirira overload uye short-circuit kunoita kuti ave akakosha mukushandiswa kubva kusimba rinogona kushandiswazve kusvika kumotokari dzemagetsi. Sezvo tekinoroji ichiramba ichifambira mberi, kunzwisisa nekushandisa maDC miniature circuit breakers kuchave kwakakosha zvikuru pakuona kuchengetedzeka nekuvimbika kwemasystem emagetsi munyika iri kuwedzera kushandisa magetsi.
