Cjm1 Electrical Electronic Adjustable Mould Case Circuit Breakers MCCB

Tsananguro pfupi:

Chinopwanya dunhu chesimbi chakaumbwa chinodzivirira simbi chinotakura ma contacts anofamba mukati. Dare resimbi rinopa dziviriro ye overcurrent uye rinogona kunyudza ma voltage surges akawandisa uku ma contacts achivhurika otomatiki kuti abvise overload yemagetsi zvakachengeteka. MCCBs dzinouya mu ratings dzakasiyana, saka zvakakosha kusarudza mhando chaiyo zvichienderana ne control panel current rating, short-circuit capacity, insulation requirements, uye electrical system voltage. Dzinewo interrupt ratings dzakakwira kupfuura ma miniature circuit breakers kuti dzishandiswe mumaindasitiri nemabhizimisi ane simba guru, akadai se control panels, OEM, uye electrical distribution equipment.

Matagi eChigadzirwa

Maputsi eDunhu reMakesi Akaumbwa (MCCB)

MuMCCB, kugona kuputsa circuit pfupi kwakarongwa kunoreva kugona kuputsa pasi pemamiriro ezvinhu akatarwa. Mushure memaitiro ekuyedza akatarwa, zvakakosha kufunga kuti circuit breaker inoramba iine current yayo yakarongwa. Kuti igutse zvinodiwa nevashandisi vakasiyana, vagadziri vazhinji vecircuit breaker ikozvino vanogovanisa kugona kuputsa circuit pfupi kwe shell rating current imwe chete muzvikamu zvakasiyana, uye vashandisi vanogona kusarudza circuit breaker yakakodzera zvichienderana nezvavanoda kubva padiki kusvika pa maximum current breakers. Akajairika uye anowanikwa munenge chero chivako kana chivakwa zvekuti anowanzoonekwa seasina basa. Asi, anoita basa rakakosha mumagetsi edu uye anofanira kuchengetedzwa kuti aenderane nezvinodiwa zvekuchengetedza zvazvino.

Muenzaniso weChigadzirwa

CJ: Kodhi yebhizinesi
M: Muchina wekupwanya dunhu wakaumbwa
1: Nhamba yeDhizaini
□:Yakayerwa current yefuremu
□:Kugona kuputsa kodhi/S inoratidza mhando yakajairika (S inogona kusiiwa)H inoratidza mhando yepamusoro

Cherechedza: Kune mhando ina dzedanda risina kusimba (N pole) dzechigadzirwa chezvikamu zvina. Danda risina kusimba rerudzi rweA harina chinhu chinogumbura chinodarika simba, rinogara richibatidzwa, uye haribatidzwe kana kudzima pamwe chete nedzimwe matanda matatu.
Pole isina simba remhando B haina chinhu chinodhonza magetsi chinodarika mwero, uye inobatidzwa kana kudzima pamwe chete nemamwe matanda matatu (pole isina simba rinobatidzwa risati radzimwa) Pole isina simba remhando C ine chinhu chinodhonza magetsi chinodarika mwero, uye inobatidzwa kana kudzima pamwe chete nemamwe matanda matatu (pole isina simba rinobatidzwa risati radzimwa) Pole isina simba remhando D ine chinhu chinodhonza magetsi chinodarika mwero, inogara ichibatidzwa uye haibatidzwe kana kudzima pamwe chete nemamwe matanda matatu.

Mamiriro Ebasa Akajairika

Kureba kwenzvimbo yekuisa hakufanirwe kudarika 2000m
Tembiricha yemhepo iri munzvimbo yakapoteredza
Tembiricha yemhepo haifanirwe kudarika +40℃
Avhareji yemutengo haifanirwe kudarika +35℃ mukati memaawa makumi maviri nemana
Tembiricha yemhepo haifanirwe kunge iri pasi pe -5℃
Mamiriro ekunze:
1. Hunyoro hwemhepo pano hahufanirwe kudarika 50% patembiricha yepamusoro ye +40℃, uye inogona kunge yakanyanya patembiricha yepasi, kana tembiricha yakaderera mumwedzi inonaya zvikuru isingapfuure 25℃ inogona kunge iri 90%, kunyungudika kwemvura pamusoro pechigadzirwa kunofanirwa kutariswa nekuda kwekuchinja kwetembiricha.
