Imwe - Phase Leakage Dziviriro Inogona Kubatanidzwa kune Vatatu - Chikamu Chechina - Wire Circuit

Single-phaseleakage muchengeti(yakagadzirwa neminiature-circuit-breaker)haikwanise kubatanidzwa kune matatu-chikamu mana-waya wedunhu.Iyo tekinoroji yakasarudzika,single-phase leakage switch MCBmudhiza rekugadzirisa kuvuza mukati me zero-sequence yazvino transformer yekuona mutsara wechikamu (kumberi) uye null mutsara weyasara yazvino vector, kana iyo inovuza yadarika 30mA, kuburikidza neterminal kuti iite iyo yekugumburisa mudziyo, ichimanikidza kutsika kwemukati. system chiito, kuti uwane basa rekuchengetedza.

Iyo wiring diagram ye2P leakage switchsezvinoratidzwa pasi apa:

Single - phase leakage mudziviriri inogona kubatana kune matatu-chikamu chechina - waya wedunhu

Single-phase leakage switchine mutsara wechikamu uye null mutsara wekutonga, kune yakaparadzana chikamu mutsara wekutonga.Kunyangwe paine tambo isina mutsetse mune matatu-chikamu mana-waya magetsi, inogona kuumbwa ne 220V voltage ine mitsara yezvikamu zvitatu zvisina tsarukano, asi haikwanise kudzora mamwe maviri echikamu mitsara.

Iyo wiring dhizaini yematatu-chikamu mana-waya leakage switch inoratidzwa mumufananidzo uri pamusoro.

Zvinokosha kucherechedza kutimatatu-phase leakage switchh yakakamurwa kuita 3P uye 3P+N, iyoleakage switchyechimiro ichi inodhura zvishoma pane imwe-chikamu leakage switch.

3P + N magetsi ekuisa waya inongoda kuziva kuti waya isina kwayakarerekera yakabatana neN, uye imwe L1, L2, L3 inogona kubatana kune iyo wiring terminal.

3 p + N kudonha kwekuchengetedza kweN mutsara kwakatwasuka (zvisinei kuti yakaparadzana muchiteshi chechiteshi), chinongedzo chinofanira kunge chiri pamberi parutivi rwekuruboshwe, null mutsara nemutsara muN, kana N tambo yakanganisa kumberi. haikwanisi kuchengetedza dunhu rinotenderera richienderera riine magetsi ekugadzirisa.
