Kushandiswa

CJMM1 series molded case circuit breaker (inozonzi circuit breaker) inoshandiswa paAC 50/60HZ power distribution network circuit ine rated insulation voltage ye800V, rated operation voltage ye690V uye rated operation current kubva pa10A kusvika pa630A, inoshandiswa kuparadzira simba nekudzivirira circuit nemagetsi kuti zvisakuvadzwe nekuda kwekuwanda kwemagetsi, short circuit, under voltage nezvimwe zvikanganiso, inoshandiswawo pakutanga mota nguva zhinji pamwe nekuwanda kwemagetsi, short circuit uye under voltage protection. Iyi circuit breaker ine mabhenefiti e small volume, high breaking capacity, short arcing (kana noarcing) etc, inogona kugadzirirwa zvishandiso zvakaita se alarm contact, shunt release, assistance contact etc, chigadzirwa chakanakira mushandisi. Residual current circuit breaker inogona kuiswa yakatwasuka (vertical installation) kana kuiswa yakatwasuka (horizontal installation). Chigadzirwa ichi chinoenderana nezvinodiwa neIEC60947-2 neGb140482.

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.

Chii chinonzi MCCB?

Ma "molded case circuit breakers" zvishandiso zvekudzivirira magetsi zvakagadzirirwa kuchengetedza circuit yemagetsi kubva kumagetsi akawandisa. Ma "current" aya akawandisa anogona kukonzerwa nekuwanda kwemagetsi kana kuti short circuit. Ma "molded case circuit breakers" anogona kushandiswa mumagetsi akasiyana-siyana uye ma "frequency" ane "depth" ne "up" muganhu wakatarwa we "trip settings" unogadziriswa. Kuwedzera kune "tripping mechanisms", ma "MCCB" anogonawo kushandiswa se "manual disconnection switches" kana paine emergency kana "maintenance operations". Ma "MCCB" akajairwa uye akaedzwa kuti aone kana paine overcurrent, voltage surge, uye fault protection" kuitira kuti ave nechokwadi chekuti anoshanda zvakachengeteka munzvimbo dzese nemashandisirwo. Anoshanda zvinobudirira se "reset switch" ye "electrical circuit" kuti abvise magetsi uye kuderedza kukuvara kunokonzerwa ne "circuit overload", "ground fault", "short circuit", kana "current" inopfuura "current limitation".
