CJMM1E 1000V 250A 3P Electronic type MCCB Moulded case circuit breaker Mufananidzo Wakaratidzwa

CJMM1E 1000V 250A 3P Electronic type MCCB Moulded case circuit breaker yepamusoro-soro

Tsananguro pfupi:

·CJM1E series electronic plastic case circuit breaker (ichazonzi circuit breaker), yakakodzera AC 50H2 kana 60Hz), rated insulation voltage yayo ndeye 1000V, rated operating voltage ndeye 690V zvichidzika, uye rated operating current inosvika 800A yekuchinjana nguva nenguva mumacircuit. Mota inoshandiswa kutanga nguva nenguva. circuit breaker ine overload long delay inverse time limit, short circuit short delay inverse time limit, short circuit short delay fixed time limit, short circuit instantaneous and undervoltage protection functions, residual current protection (optional), uye phase loss protection function (optional). Inogona kudzivirira mitsetse nemidziyo yemagetsi kubva mukukuvadzwa. circuit breaker ine maficha ekudzivirira akazara uye akarurama, anogona kuvandudza kuvimbika kwemagetsi uye kudzivirira kudzimwa kwemagetsi zvisina kufanira.

·Macircuit breaker akakamurwa kuita mhando mbiri: M type (higher breaking type) uye H type (high breaking type) zvichienderana ne rated limit short circuit breaker. Iyi circuit breaker ine hunhu hwe diki, high breaking capacity, short arcing, uye anti-vibration.

·Circuit breaker inogona kuiswa yakatwasuka (kureva, yakatwasuka) kana yakatwasuka (kureva, yakatwasuka).
·Circuit breaker haigone kudzoserwa kumashure, kureva kuti, 1, 3, uye 5 chete ndizvo zvinotenderwa kubatanidzwa pawaya dzemagetsi uye 2, 4, uye 6 zvinotenderwa kubatanidzwa pawaya dzinotakura zvinhu.

Mamiriro Ekushanda Uye Kuisa

·Kureba: ≤2000m;
·Tembiricha yekunze: -5°C~+40°C;
·Inogona kutsungirira simba remhepo ine hunyoro;
·Inogona kutsungirira simba remushonga wemunyu uye mhute yemafuta;
·Chikamu chekuisa chedunhu guru remuchina wekupwanya dunhu ndeche III, uye chikamu chekuisa chemamwe maseketi ekubatsira uye maseketi ekudzora i ll;
·Kana tembiricha yepamusoro iri +40°C, hunyoro hwemhepo hahupfuure 50%. Hunyoro hwakanyanya hunobvumirwa kana hunyoro hwakaderera. Matanho akakosha anofanira kutorwa kugadzirisa kutonhora kwemhepo dzimwe nguva nekuda kwekuchinja kwetembiricha;
·Kurerekera kwakanyanya i22.5°;
·Munzvimbo isina njodzi yekuputika, uye umo nzvimbo yacho isina magasi neguruva rinofambisa mhepo rinogona kukanganisa simbi nekuparadza insulation;
·Munzvimbo isina mvura kana sinou.

·Kugadziriswa kweIr1 current inononoka kwenguva refu kunogona kugadziriswa kubva pamapoinzi mana kusvika gumi zvichienderana nema currents akasiyana-siyana ecircuit breaker;
·Nguva yekunonoka kwenguva refu t1 inogona kugadziriswa pamapoinzi mana;
·Ir2 yemagetsi inononoka kushanda kwenguva pfupi inogona kugadziriswa pa10 points;
Kugadziriswa kwenguva pfupi kwe t2, kugadziriswa kwemapoinzi mana kunowanikwa;
Ir3 inoshanda nekukurumidza inogona kugadziriswa pa9 kana 10 points;
Iyo pre-alarm action current Ir0 inogona kugadziriswa pa7 points;
Test terminal, inoshandiswa kuona kukosha kwekugadzirisa kwazvino kwe electronic tripper;
Mirayiridzo yekushanda yekuburitsa magwaro emagetsi;
Mirayiridzo yekuvhura alarm;
Chiratidzo chekuremerwa zvakanyanya;
Bhatani rerwendo.
