EW7-2000 Air Circuit Breaker
Chigadzirwa Zvidimbu
Tsananguro yeChigadzirwa
EW7-2000 imhepo inopwanya mhepo yose yakagadzirirwa network dzekugovera dzeAC 50Hz, ine ratio yemagetsi kubva pa200 kusvika 6300A uye ratio yemagetsi ye400V/690V. Inonyanya kushandiswa kugovera simba remagetsi nekudzivirira mitsetse nemidziyo yemagetsi kubva kunjodzi dzakadai sekuwedzeredza, under-voltage, short circuit, uye single-phase ground faults. Inogona zvakare kushanda se solatory switch. Dhizaini yayo inoenderana neIEC60947-2 uye GB/T 14048.2 standards, ine dziviriro yakasarudzika yepamusoro kudzivirira kudzimwa kwemagetsi kusingakoshi uye kuwedzera kuvimbika uye kuchengetedzeka kwemagetsi. Ma breaker ane ratio ye630A uye pasi anogonawo kushandiswa pakutangira mota nguva nenguva.
Iyi breaker ine kugona kukuru kwekupwanya (kusvika ku100kA), kupenya kwe zero arc, kugamuchira kupinda kwetambo yepamusoro nepasi, uye saizi diki. Yakashongedzwa ne controller yakangwara inopa mabasa akawanda ekudzivirira anosanganisira kunonoka kwenguva refu, kunonoka kwenguva pfupi, kudzivirira kukanganisa kwepasi nekukurumidza, uye kudzivirira kukanganisa kwepasi, izvo zvinogona kuiswa kune inverse-time kana definite-time modes. Controller (3M/3H types) inoyerawo uye inoratidza ma parameter akadai se voltage, frequency, uye power. Ma models epamusoro (2H/3H types) anotsigira Modbus neDevice-net communication protocols ekutarisa kure uye integrated bus management. Mhando dzakasiyana dze mechanical interlocks uye drawer locks dziripo kuti dzive nechokwadi chekuti mashandiro adzo akachengeteka. Kushanda kwadzo kunogona kukanganiswa kana tembiricha ye ambient ichiwedzera.
Chinopwanya chinofanira kuiswa pasi pekupisa kwemhepo kunobva pa -5°C kusvika +40°C uye pakukwirira kusingapfuure mamita 2000, nedziviriro yeIP30/IP40 (kana chakaiswa mukati menzvimbo yakavharirwa). Panguva yekuisa, kutsveyama kwayo kwakatwasuka hakufanirwe kudarika 5°. Mifananidzo yehukuru hwekuisa inotsanangudza zviyero zvekunze uye zviyero chaizvo zvekucheka nenzvimbo (semuenzaniso, dhayamita yegomba φ12) inodiwa pakubatanidza busbar yeEW-2000 series fixed breakers (200-2000A, 3-pole/4-pole), ichipa gwara rakajeka remakanika rekuisa kwakakodzera uye waya yebusbar mukati meswitchgear.

Hunhu hwechigadzirwa
Kuputsika kwakanyanya, hapana arc inobhururuka;
Basa rekuchengetedza kupatsanura;
Mitsetse yose iri pamusoro nepazasi inopinda inogamuchirwa.
Diki muhukuru;
Kuona nekuchengetedza zvinosarudzwa zvinoita kuti zvive nyore kusarudza zvinodiwa zvakasiyana-siyana.
Nzira dzekubatanidza waya dzakasiyana-siyana, kusanganisira mhando dzakatwasuka nedzakatwasuka, dziri nyore kuisa.
Madhiraivha eLCD emhando ye3M ne3H achangoburwa, pamusoro pedhiraivha nedziviriro yazvino, ane mabasa ekuyera nekudzivirira voltage, frequency, phase sequence, simba, nezvimwewo, zvichiita kuti mabasa awo ave nesimba.
Dziviriro yeRegional Selective Interlocking (ZSI) inoderedza zvakanyanya nzvimbo inokanganiswa nekudzimwa kwemagetsi nekuda kwezvikanganiso, zvichiita kuti pave nedziviriro yakavimbika.
Yakashongedzerwa nemhando dzakasiyana dzemakinika ekukiya (rudzi rwelever uye rudzi rwetambo yesimbi), madhirowa ekukiya, magonhi ekukiya uye makiyi enzvimbo yekukiya ane vimbiso yekuchengetedza kuti macircuit breakers akwanise kukiya.
Vanodzora vane hungwaru vemhando ye2H ne3H vane mabasa ekutaurirana uye ekutarisa. Vanogona kushandisa nzira dzeMod bus neDevice-net, zvichiita kuti mabhazi agadziriswe zviri nyore. Vanogona kuwana simba rekutonga kure, kuyerwa kure, kuratidza masaini kure uye kugadzirisa kure.
