Molded Case Circuit Breakers: Dziviriro Inoshandiswa Pamagetsi

suma:

Muinjiniya yemagetsi,macircuit breakers ekesi akaumbwa (MCCBs) zvinhu zvakakosha mukudzivirira masisitimu emagetsi kubva pakuwanda kwemagetsi, mashort circuits nezvimwe zvinhu zvinokanganisa mashandiro emagetsi.MCCBsanoshandiswa zvakanyanya mumabasa akasiyana-siyana mudzimba, mabhizinesi nemaindasitiri kuitira kuti masisitimu emagetsi ashande zvakanaka uye zvakachengeteka. Muchinyorwa chino, tichaongorora mashandisirwo, maficha, uye zvinofungwa nezveMCCBs.

Kushandiswa kwemuputsi wedunhu wakaumbwa:

MCCBszvinoshandiswa mumhando dzakasiyana siyana dzinosanganisira:

1. Mashandisirwo emaindasitiri: MaMCCB anowanzo shandiswa mumaindasitiri kudzivirira masisitimu emagetsi kubva pakuwanda kwezvinhu, mashort circuits, nezvimwe zvinhu zvinokanganisa. Mashandisirwo aya anosanganisira kugadzira, mafuta negasi, migodhi nedzimwe nzvimbo dzemaindasitiri.

2. Mashandisirwo ekutengeserana: Molded case circuit breakers anoshandiswa mumabasa ekutengeserana, akadai sezvitoro, mahotera, zvivako zvemahofisi, nezvimwewo, kuitira kuti masisitimu emagetsi ashande zvakanaka uye zvakachengeteka.

3. Mashandisirwo edzimba: Ma "molded case circuit breakers" anoshandiswa mudzimba kuti ave nechokwadi chekuti vagari vedzimba vakachengeteka. Anoiswa mumabhokisi ekuparadzira zvinhu kuti adzivirire ma "circuit" kubva kumatambudziko emagetsi.

Zvinhu zvema "molded case circuit breakers":

1. Rated current: Rated current yema molded case circuit breakers yakasiyana, kubva pamaampere mashoma kusvika kumaampere zviuru zvakawanda. Iyi ficha inoita kuti ikwanise kushandiswa mumabasa akasiyana-siyana.

2. Hunhu hwekugumburwa: Chinopwanya dunhu chekasi chakaumbwa chine hunhu hwekugumburwa, izvo zvinoita kuti dunhu rigumbuke kana paine kukanganisa kwemagetsi kudzivirira kukuvara kwakawanda. Hunhu hwekugumburwa hunogona kuva hwekupisa kana hwemagineti.

3. Kukwanisa kupwanya kwakanyanya: Molded case circuit breaker ine kugona kupwanya kwakanyanya uye inogona kumira kutadza kukuru pasina kupwanya. Iyi ficha inoita kuti circuit idzivirire kubva mukukuvadzwa.

4. Kusarudza: Chinopwanya dunhu remagetsi chakaumbwa chinoita kuti pave nesarudzo yemagetsi, kureva kuti, chinopwanya dunhu remagetsi chakaumbwa chiri pedyo nepanenge paine fault trips, nepo mamwe macircuit ari mumagetsi asingakanganiswi.

Kungwarira pakusarudza ma "molded case circuit breakers":

1. Rated current: Pakusarudza mokupwanya circuit case case, rated current yemagetsi system inofanira kutariswa kuti ive nechokwadi chekuti mokupwanya circuit case ...

2. Rudzi rwekukundikana: Rudzi rwekukundikana kunoitwa neMCCB kudzivirira inyaya huru pakusarudza MCCB. Semuenzaniso, mamwe maMCCB akagadzirirwa kudzivirira kukundikana kwekupisa, nepo mamwe akagadzirirwa kudzivirira kukundikana kwemagineti.

3. Tembiricha yekunze: Tembiricha yekunze kwenzvimbo ine molded case circuit breaker inokoshawo. MCCB ine chiyero chekupisa uye inogona kusashanda zvakanaka kana tembiricha yekunze ikapfuura chiyero cheMCCB.

Muchidimbu: MCCB chinhu chakakosha muhurongwa hwemagetsi sezvo ichidzivirira kubva kumatambudziko emagetsi. Ine ma currents akasiyana, maitiro ekugumburwa uye kugona kutyoka, saka yakakodzera kushandiswa kwakasiyana. Pakusarudza MCCB, current rating, fault type, uye ambient temperature zvinofanirwa kutariswa kuti zvive nechokwadi chekuti mashandiro azvo anoshanda zvakanaka.
