Maitiro uye nzira yekutarisa rwendo uye nekuvhara zvakare kutadza kwemhepo yedunhu breaker (ACB)

Air circuit breaker(ACB) kugumburwa, kuvhara zvakare kwakundikana

1. Chekutanga tarisa kanaAir circuit breakerhaina kugumburwa netsaona

Non-accident trip zvinoreva rwendo rusina dunhu diki kana mhosva yakawandisa.Pane zvikonzero zvakawanda zveAir circuit breakerkwete kuvhara.Chokutanga pane zvose, zvakakosha kuti uone rwendo rwakakonzerwa nekupfupika kwedunhu uye kuwandisa, kana kutiair circuit breakerpachayo kana kuti control loop yakanganisa.Tsvaga uye uone kana dunhu rakashata kana kutiair breakerpachayo ine mhosva.
Mushure mekuona chikanganiso chemhepo inopwanya mhepo, dhiza dhizaini (inoreva iyodhirowa mhando air circuit breaker) kuti iongororwe.

2. Universal type circuit breaker yakajairika kugadzirisa dambudziko

(1) Mutambo wedunhu haugone kuvharwa nekuda kwekurasikirwa kwesimba mune undervoltage tripping mudziyo.Kana iyo voltage yakanyanya kuderera kana coil ye undervoltage tripping mudziyo isisina simba, wedunhu rinotyora rinofamba uye harigone kuvharwa zvakare.Mamiriro mana anotevera anogona kuita kuti undervoltage tripper coil ishaye simba.

• (1) Iyo yekudzivirira yedunhu fuse inopeperetswa, senge RT14, zvichikonzera kuvharika kwedunhu uye kurasikirwa kwesimba rekugumbusa coil ye undervoltage tripping mudziyo;
• (2) Bhatani rekuvhara, relay kuonana, redunhu rinotyora rinobatsira kubata musoro wakashata kubata, kukuvara kwechikamu, kunogona kutungamira kuvharika kwedunhu, kugumbura coil simba kurasikirwa;
• (3) Iyo yekubatanidza waya muchiuno yakaputsika, uye crimping screw yakasununguka uye yakasununguka, iyo inotungamira kudunhu yakavharwa, uye coil inogumburwa inobviswa;
• (4) Nekuda kweiyo coil yekuburitsa undervoltage iri munzvimbo yekushanda yemagetsi kwenguva yakareba, kusvibiswa kwezvakatipoteredza uye armature haina kuchinjika, kana mukaha wemhepo pakati pepakati uye armature yakakura kwazvo, zviri nyore kuita. ita kuti ikozvino ive yakakura uye inotungamirira kusunungurwa coil kupisa uye kupisa, kurasikirwa nebasa rekusunungura coil.
• Mhosva iri pamusoro kuburikidza nekutarisa uye nyore kuongorora uye bvunzo inogona kuita mutongo chaiwo, saka kana yangowanikwa kukanganisa kunofanirwa kubviswa nekufamba kwenguva, senge wakasununguka kubata kuomesa, kukuvara kwechikamu uye coil kupisa inoda kutsiviwa.

(2) Mechanical system kukundikana, zvichiita kuti muparadzi wedunhu arege kuvhara.Mushure mokugumburwa nekuvhara dhizaini yekushanda kwemagetsi nguva dzakawanda, nzira yacho yakasakara zvakanyanya uye zvikanganiso zvinotevera zvinogona kuitika.

• (1) Mota yekufambisa michina inopfeka, senge ME switch worm giya, kukuvara kwehonye, ​​haigone kutyaira yedunhu rinotyora rekushandisa dhizaini, kuvhara.Worm giya, kutsiva worm yakanyanya kuoma, kudiwa kwehunyanzvi kugadzirisa.
• (2) yemahara yekutsika meshini inopfeka, zvekuti inotyora wedunhu inonetsa kusungirira, kugumburwa zviri nyore, dzimwe nguva kumanikidzwa kusungirira, kana paine kuzunguza, rwendo;Dzimwe nguva mushure mebuckle, chivharo chakavharwa chinotsvedza.Panguva ino, siruu inogadzirisa inofanirwa kutenderedzwa kuti igadzirise chinzvimbo chekugumbusa hafu shaft uye kutsika bhandi, kuitira kuti nzvimbo yekubata iite 2.5mm2, uye zvikamu zvinoenderana zvinofanirwa kutsiviwa kana zvichidikanwa.
• (3) Chitubu chekuchengetedza simba cheiyo inoshanda sisitimu yakashata.Iyo yekupwanya yekuchengetedza simba chitubu cheiyo inoshanda meshini inosunungura kana kurasikirwa nekusimba kwayo mushure mekufamba kwakawanda, uye simba rekuvhara rinova diki.Paunenge uchivhara, iyo mana-bar maitiro emutsigiri wedunhu haigone kusundidzirwa kunzvimbo yakafa, uye iyo nzira haigone kuzvichengeta painovhara.Nokudaro, muparadzi wedunhu haagoni kuvharwa kazhinji.Chitubu chekuchengetera chinofanira kutsiviwa.
• (4) Iyo inoshanda sisitimu haichinjike, uye pane yakamira chiitiko.Nekuti rudzi urwu rwekutyora kwedunhu haruna kuvharirwa zvizere, kana screws, nzungu uye mimwe mitumbi yekunze yakasiiwa netsaona mumashandiro ekushandisa, kuitira kuti kuvhiyiwa kwemugero wedunhu kunobata chiitiko, kunokanganisa kuvhara;Uye zvakare, iyo inotenderera uye inotsvedza zvikamu kushomeka kwegirisi yekuzora, iyo yekuvhura simba rekuchengetedza chitubu cheiyo inoshanda sisitimu yakaremara zvishoma, uye wedunhu rinotyora haakwanise kuvhara brake.Nokudaro, kana kukundikana kwepamusoro kukaitika, kunze kwekutarisa maitiro ekushanda, hapana mutsauko, asiwo kuisa mafuta ekuzora mukati mekutenderera uye chikamu chinotsvedza.
