CJ:Kodhi yebhizinesi
M:Mould kesi circuit breaker
1:Design Nhamba
□:Yakayerwa ikozvino yefuremu
□:Kutyora kugona hunhu kodhi/S inoreva yakajairika mhando (S inogona kusiiwa)H inoreva mhando yepamusoro
Cherechedzo: Kune mhando ina dzema neutral pole (N pole) yezvikamu zvina chigadzirwa. The neutral pole yerudzi A haina kugadzirwa ne over-current tripping element, inogara yakabatidzwa, uye haina kubatidzwa kana kudzimwa pamwe chete nezvimwe. matanda matatu.
Bango rakarerekera rerudzi B harina kurongedzerwa ne-over-current tripping element, uye rinobatidzwa kana kudzima pamwe chete nemamwe mapango matatu (i neutral pole inobatidzwa isati yadzimwa) yazvino, uye inobatidzwa kana kudzima pamwe chete nemamwe matanda matatu (iyo isina kwairi danda inobatidzwa isati yadzimwa) Iyo isina kwayakarerekera yerudzi D inoshongedzerwa nepamusoro-ikozvino chinhu chekutsika, inogara ichibatidzwa uye haibatiswe. pamusoro kana kudzika pamwe chete nemamwe matanda matatu.

Molded case circuit breakers zvigadziriso zvemagetsi zvakagadzirirwa kuchengetedza dunhu remagetsi kubva kune yakawandisa ikozvino.Iyi yakawandisa ikozvino inogona kukonzerwa nekuda kwekuremerwa kana kupfupika kwedunhu.Iyo molded kesi circuit breakers inogona kushandiswa muhupamhi hwemagetsi uye ma frequency ane yakatsanangurwa yakaderera uye yepamusoro muganho weinogadziriswa rwendo marongero.Pamusoro pemakina ekugumbusa, maMCCB anogona zvakare kushandiswa semanyorerwo ekudzimisa switch kana paine emergency kana kugadzirisa mabasa.MCCBs akamisikidzwa uye akaedzwa overcurrent, voltage surge, uye kuchengetedzwa kukanganisa kuti ive nechokwadi chekushanda kwakachengeteka munzvimbo dzese nemashandisirwo.Ivo vanoshanda zvinobudirira sereset switch yedunhu remagetsi kudzima simba uye kuderedza kukuvadzwa kunokonzerwa nekuremerwa kwedunhu, kukanganisa kwepasi, mapfupi maseketi, kana ikozvino inodarika iyo inomisikidza ikozvino.
MCCB kana fuse chinhu chemagetsi chinowanzoshandiswa muindasitiri kuchengetedza midziyo yemagetsi nemasisitimu.Muhupenyu hwezuva nezuva, MCCB inoshandiswa zvakanyanya.Zvimwe zvakajairika zveMCCB zvikumbiro zvinotsanangurwa pazasi.
1.Energy distribution: MCCB inogona kubatsira installers kugovera mitoro yegridi kune zvakasiyana-siyana zvemagetsi.Kuburikidza neMCCB, vashandisi vanogona kudzora zvakachengetedzeka kugoverwa kwesimba uye ikozvino yechinhu chimwe nechimwe.
2.Short circuit protection: Basa guru reMCCB nderokuzvigura dunhu kana chidimbu chiduku chikaitika.Izvi zvinodzivirira kukuvara kwemidziyo, kuburitswa kwezvinhu zvine njodzi semoto.
3.Kudzivirirwa kwekudzivirira: Kufanana nekuchengetedzwa kwedunhu pfupi, MCCB inogonawo kudzivirira michina kubva pakuremerwa.Izvi zvinogona kuwanikwa nekuseta mabreaker breakers kudzivirira kukuvadzwa kwemagetsi kunokonzerwa nekuremedza midziyo.
4.Kudzivirirwa kweJenereta: MCCB inoshandiswa zvakanyanya pakuona nekuchengetedzwa kwemajenereta makuru.Iyo inogona kutarisa yakajairwa kushanda kwejenareta, kuona matambudziko uye kumisikidza yedunhu breaker kudzivirira system.
5.Power transformer kudzivirirwa: MCCB inogona kudzivirira mushanduri kubva pakuremedza uye kutarisa kupisa kwepamusoro-soro panguva imwe chete.
6.Movable cylinder protection: MCCB inoshandiswa zvakanyanya mukrete, simenti uye mineral crushers.Inoona mapfupi maseketi uye kuwandisa kwemidziyo, nekudaro ichidzivirira michina kubva mukukuvadzwa.
Mukupedzisa, maMCCB anoshandiswa zvakanyanya uye anoita basa rakakosha munzvimbo dzakasiyana dzemagetsi nemakina.Pakusarudza MCCB, zvinhu zvakasiyana-siyana zvinoda kunyatsotariswa kuitira kuti ive nechokwadi chekuchengetedzwa uye kuvimbika kwehurongwa, kusanganisira ikozvino kutakura simba, kushanda zvakanaka, nzvimbo inoshandiswa, uye mamwe maparameter anokosha.
