Sei MCBs dzichifamba kakawanda?Nzira yekudzivirira sei MCB kugumburwa?

Kukanganisa kwemagetsi kunogona kuparadza hupenyu huzhinji nekuda kwekuremerwa kana mapfupi maseketi, uye kudzivirira kubva pakuremerwa & pfupi pfupi, MCB inoshandiswa.Miniature Circuit Breakers(MCBs) zvigadziriso zvemagetsi zvinoshandiswa kuchengetedza dunhu remagetsi kubva kuOverload & Short Circuit.Zvikonzero zvikuru zvekupfuura zvinogona kunge zviri pfupi dunhu, kuwandisa kana kunyange kukanganisa dhizaini.Uye pano mune ino blog, tichave tichikuudza chikonzero cheMCB kugumburwa kazhinji uye nzira dzekuzvidzivirira.Heino, tarisa!

Zvakanakira MCB:

● Mhepo yemagetsi inodzima pakarepo kana mamiriro asina kunaka etiweki amuka

● Nzvimbo yakakanganisika yedunhu remagetsi inogona kuonekwa zviri nyore, sezvo knob inoshanda ichisimuka panzvimbo panguva yekugumburwa.

● Kukurumidza kudzorerwa kwekugovera kunogoneka muchiitiko cheMCB

● MCB haina njodzi pamagetsi kupfuura fiyuzi

Hunhu:

● Mitemo iripo kwete kupfuura 100A

● Mamiriro erwendo kazhinji haachinjiki

● Thermal uye magnetic operation

Zvimiro uye mabhenefiti eMCB

1. Dziviriro kubva mukuvhunduka nemoto:

Chekutanga uye chinonyanya kukosha cheMCB ndechekuti inobatsira mukubvisa kusangana netsaona.Inoshandiswa uye inodzorwa pasina dambudziko.

2. Anti welding contacts:

Nekuda kweiyo anti-welding pfuma, inovimbisa hupenyu hwepamusoro uye kuchengetedzeka kwakawanda.

3. Chiteshi chekuchengetedza kana nhapwa screws:

Bhokisi remhando terminal dhizaini inopa kumisa kwakaringana uye inodzivirira yakasununguka kubatana.

Zvikonzero nei MCBs ichifamba kazhinji

Pane zvikonzero zvitatu zveMCBs kufamba kazhinji:

1. Dunhu rakaremerwa

Kuremedza kwedunhu kunozivikanwa kuti ndicho chikonzero chinowanzo konzeresa kufamba kwedunhu.Zvinongoreva kuti tirikumhanyisa akawanda anorema-anoshandisa magetsi panguva imwe chete padunhu rimwe chete.

2. Short circuit

Chikonzero chinotevera chine ngozi ipfupi dunhu.Dunhu redunhu rinoitika kana waya/chikamu chabata imwe waya/chikamu kana kubata waya “ineutral” mudunhu.Iyo yakakwira ikozvino inoyerera kana waya mbiri idzi dzichibata kugadzira inorema ikozvino kuyerera, kupfuura iyo dunhu rinogona kubata.

3. Chikanganiso chepasi

Chikanganiso chepasi chinenge chakafanana nechepfupi pfupi.Ichi chiitiko chinoitika kana waya inopisa inobata pasi pasi.

Chaizvoizvo, tinogona kutaura kuti nguva iyo dunhu rapwanyika, zvinoreva kuti ikozvino inodarika AMPs iyo system yako isingagone kubata, kureva system yakawandisa.

Mabreaker mudziyo wekuchengetedza.Yakagadzirirwa kuchengetedza kwete chete midziyo asi wiring uye imba zvakare.Saka, kana MCB ikafamba, pane chikonzero uye chiratidzo ichi chinofanira kutorwa zvakanyanya.Uye kana iwe ukagadzirisa zvakare MCB, uye inokurumidza kufamba zvakare, zvino inowanzoratidza yepfupi yakananga.

Chimwe chikonzero chinowanzo konzera kuti mupunzi afambe kubatanidza magetsi uye anogona kugadziriswa nyore nyore nekuaomesa.

Mamwe matipi akakosha ekudzivirira MCBs kugumburwa

● Tinofanira kukunura midziyo yose kana isiri kushandiswa

● Tinofanira kuziva kuti midziyo mingani inobatanidzwa panguva yekupisa kana kutonhora

● Unofanira kuva nechokwadi chokuti hapana tambo yemudziyo wako yakakuvara kana kutyoka

● Dzivisa kushandisa tambo yekuwedzera uye tambo dzemagetsi kana uine mashoma ekuburitsa

Short circuits

Circuit breaker nzendo dzinomuka kana system yako yemagetsi kana imwe yemaapplication auri kushandisa ine ipfupi.Mune dzimwe dzimba, zvakaoma kuziva kuti pfupi iri papi.Uye kuti uwane pfupi mumudziyo, shandisa maitiro ekubvisa.Batidza simba uye ubate mudziyo wega wega chimwe nechimwe.Ona kana chimwe chishandiso chichikonzera rwendo rwekutyora.

Saka, ndosaka MCB ichifamba kazhinji uye nzira dzekudzivirira MCB kutsika.
