I. Ongororo uye nzira yekurapa yekukanganisa chiitiko chinokonzera
1. Mushure mokunge coil yakasimbiswa, iyo contactor haiiti kana kuita zvisina kujairika
A. The coil kudzora redunhu akadimburwa;ona kana iyo wiring terminal yakatyoka kana yakasununguka.Kana pane kuputika, shandura waya inoenderana.
b.Iyo coil yakakuvadzwa;kuyera kushorwa kwekoiri ine multimeter.Kana kupikisa kuri, shandura coil.
c.The thermal relay haina kugadziriswa mushure mekuita.Shandisa multimeter resistance gear kuti uone kukosha kwekupikisa pakati pezvikamu zviviri zvekuvhara nguva dzose kwekushisa kwekushisa, sezvazviri, wobva wadzvanya bhatani reset relay relay.
d.The rated coil voltage yakakwira kupfuura mutsara voltage.Shandura coil yakagadziridzwa kuti control line voltage.
e.Bata chitubu pressure kana kuburitsa spring pressure yakakurisa.Adjust the spring pressure or replace the spring.
Bata f, Bhatani rekubata kana wekubatsira kuonana nebhatani rakashata Gadzirisa iyo kana chinja zvinoenderana.
Iyo g nemacontacts zvakakurisa. Rongedza matangi epamusoro
2. Mushure coil iri powered kure, contactor haazobudisi kana kunonoka kusunungurwa.
A. The column in the magnetic system haina air gap, uye yasara magineti yakakura zvakanyanya.Bvisa chikamu chepole surface pane yasara maginege kuti gap riite 0.1~0.3mm, kana kuve ne0.1uF capacitor. zvakafanana pamigumo miviri yekoiri.
b.Kumusoro kweiyo activated contact core imafuta kana girisi mushure menguva yekushandiswa.Pukuta girisi yehutu pamusimboti wepamusoro, nzvimbo yepakati inofanira kunge yakadzikama, asi haifaniri kunge yakanyanya kujeka, kana zvisina kudaro zviri nyore kukonzera kunonoka kusunungurwa.
c.Bata anti-melting welding performance haina kunaka.Kana iyo mota kana mutsara ipfupi dunhu, iyo yakakwira ikozvino inoita kubata. Musoro wakanyatso kusungirirwa uye haugone kuburitswa, uye iyo yakachena sirivha yekubata iri nyore kunyungudutsa welding.Kukurukurirana kukuru kwe AC contactor kunofanira kusarudzwa nesirivha. -based alloy ine yakasimba kunyunguduka uye welding kuramba, senge sirivheri nesimbi, sirivheri uye nickel, nezvimwe.
d.Gadzirisa iyo control wiring kukanganisa zvinoenderana neiyo control wiring diagraph.
Chetatu, iyo coil inopisa, yakapiswa kana kukuvadzwa.
A. Kuwanda uye chiyero chesimba chemhete zvinodarika zvinodiwa zvehunyanzvi zvechigadzirwa. Dzorera coil kuitira frequency uye kuenderera kwesimba.
b.Nzvimbo yepakati haina kuenzana kana kuti mukaha wemhepo we column wakakurisa. Chenesa danda kana gadzirisa core, wotsiva coil.
The c, mechanical damage, chikamu chekufamba chakanamira.Gadzirisa ma mechanical parts uye wotsiva coil.
d.Kana tembiricha ye ambient yakanyanya kukwira, kana kuti coil insulation yakuvadzwa nekuti mweya wanyorova kana kuti gasi raita ngura, tsiva coil.
Chechina, ruzha rwemagetsi emagetsi rwakakura zvakanyanya.
A. Short redunhu mhete anotyora uye kutsiva pfupi redunhu mhete kana musimboti
b.Iyo yekubata chitubu pressure yakakurisa, kana kana iyo yekubata ikafamba yakawandisa, gadzirisa chitubu chekubata pressure kana kuderedza kuwandisa.
c.Pini yekubatanidza pakati peiyo armature uye mekiniki chikamu chakasununguka, kana iyo clamp screw yakasununguka.Isa pini yekubatanidza uye simbisa iyo clamp screw.
shanu, alternate short circuit
A. The contactor inounganidza huruva yakawandisa kana tumiti nemvura uye gasi.Chiyero chemafuta chinoita kuti insulation ikuvadze.Iyo yekubatanidza inofanirwa kucheneswa kazhinji, kuchengetwa, yakachena uye yakaoma.
Mub.Nemagetsi anopindirana chete, nguva yekushandura yekushandura inogadziriswa yekubatanidza ipfupi pane inopisa arc nguva.Wedzera ma mechanical interlocks.
Muna c.Kana iyo arc hood ikatsemuka, kana zvikamu zvecontator zvakakuvadzwa nearc, kana kutsiva zvikamu zvakakuvadzwa.
Pamusoro pezvinetso zvakajairika mukuita kwekutaurirana kutaurirana kushanda, kukanganisa kwakaita ongororo pfupi, uye kuisa pamberi mhinduro, mune chaiyo mashandiro maitiro achasangana nemamwe matambudziko, chero isu tichigona nzira yekutaurirana, yakasanganiswa neyakapfuma ruzivo. mukuita, matambudziko uye zvikanganiso zvichave kudzidziswa kwakakodzera kutarisisa kwako!
Nonoise ye AC contactor
The achimhanya AC contactor ane ruzha chaizvo uye anogona kurapwa sezvinotevera:
1. Kana magetsi emagetsi asina kukwana uye kusveta kwe electromagnet hakuna kukwana, tinofanira kuedza kuwedzera simba rekushanda kwedunhu.
2. Kana iyo magnetic system isingabatanidzi zvisina kufanira kana kuzununguswa kana chidimbu chemichina chakanamatira, nheyo yesimbi haigoni kuderedzwa, zvichiita kuti ruzha.Iyi hurongwa inofanira kugadziriswa kuti ione uye kubvisa zvikonzero zvekushanduka.
.
4. Electromagnet ruzha runogadzirwa nekuda kwekunyanya kubata chitubu kudzvanywa, saka kazhinji gadzirisa yekubata chitubu pressure.
5. Muchiitiko chemheremhere inomuka kubva pakuputsika kwechidimbu chemhete, mhete yepakati kana pfupi inofanira kuchinjwa.
6. Kana iyo core pole surface inopfeka yakawandisa uye isina kuenzana, musimboti unofanirwa kutsiviwa.
7. Dunhu pfupi pakati pekutendeuka, kazhinji kutsiva coil.
Kuti uwane mamwe mazano ehunyanzvi, ndapota teerera kune Jingdian Port.
