I. Kusarudzwa kwe AC contactors
Iwo akatemerwa ma parameter eiyo contactor anonyanya kutariswa zvichienderana nevoltage, yazvino, simba, frequency uye yekushanda sisitimu yemidziyo inochaja.
(1) Iyo coil voltage yeiyo contactor inowanzosarudzwa zvichienderana neyakayerwa voltage yetambo yekudzora.Tichifunga nezvekuchengetedzwa kwemutsara wekutonga, inowanzosarudzwa maererano nemhepo yakadzika, iyo inogona kurerutsa mutsara uye kufambisa wiring.
(2) Kusarudzwa kweiyo yakatemerwa ikozvino ye AC contactor inofanirwa kutariswa nemhando yekuremerwa, shandisa nharaunda uye inoenderera yekushanda nguva.Iyo yakarongerwa ikozvino yeanobatika inoreva iyo yakanyanya kubvumidzwa ikozvino yeanobatika pasi pekushanda kwenguva refu, ine nguva ye8 h, uye yakaiswa pane yakavhurika control board.Kana mamiriro ekutonhora asina kunaka, iyo yakatemerwa ikozvino yeanobatika inosarudzwa ne 110% ~ 120% yeiyo yakatarwa ikozvino yemutoro.Kune mota dzinoshanda kwenguva refu, nekuti iyo oxide firimu iri pamusoro peiyo yekusangana haina mukana wekucheneswa, kupikisa kwekubata kunowedzera, uye kupisa kwekusangana kunopfuura kukwira kunobvumidzwa kwekushisa.Muchisarudzo chaicho, iyo yakayerwa ikozvino yecontactor inogona kuderedzwa ne30%.
(3) Mutoro wekushanda frequency uye mamiriro ekushanda ane simba guru pakusarudzwa kweAC contactor capacity.Kana simba rekushanda remutoro richipfuura ratidzo yekushanda frequency, iyo yekusangana kweiyo contactor ichawedzerwa zvakakodzera.Kune kazhinji kutanga uye kubviswa mitoro, iyo yekubata yekubata inofanidza kuwedzera zvinoenderana nekudzikisa iyo yekubata ngura uye kuwedzera hupenyu hwesevhisi.
2. Common kukanganisa kuongorora uye kuchengetedza yakaderera-voltage AC contactor
AC macontactor anogona kutyora kazhinji panguva yebasa uye anogona kupfeka anobatika macontact panguva yekushandisa.Panguva imwecheteyo, dzimwe nguva kushandiswa kusina kunaka, kana kushandiswa mumamiriro ezvinhu akaoma, kuchaitawo kupfupisa hupenyu hweanobata, zvichikonzera kukundikana, saka, mukushandiswa, asiwo kusarudza maererano nemamiriro ezvinhu chaiwo, uye mukushandiswa kunofanira. kuchengetedzwa nenguva, kudzivirira kurasikirwa kukuru mushure mekukundikana.Kazhinji, zvikanganiso zvakajairika zve AC contactors kutadza kwekubata, coil zvikanganiso uye mamwe ma electromagnetic mechanical kukanganisa.
(1) Bata melt welding
Mukuita kwesimba uye static kubata kusveta, iyo yekubata kumeso yekubata kuramba yakakura, ichikonzera nzvimbo yekubatana mushure mekunyunguduka uye welding pamwe chete, haigone kutyorwa, inonzi iyo contact melt welding.Mamiriro ezvinhu aya anowanzo kuitika mukushanda frequency yakakwira zvakanyanya kana kuwedzeredza kushandiswa, kuremerwa kupera kupfupi dunhu, kubata chitubu kudzvanya kudiki, mechanical jam resistance, etc. Kana mamiriro aya aitika, anogona kubviswa nekutsiva akakodzera contactor kana kuderedza mutoro, kubvisa kukanganisa-pfupi, kutsiva kusangana, kugadzirisa kudzvanywa kwepamusoro kwekubatana, uye kukonzera jam factor.
(2) Bata mapoinzi ekupisa kana kupisa
Zvinoreva kuti iyo calorific kupisa kwekushanda kwekushanda kunodarika chiyero chekushisa.Mamiriro ezvinhu aya anowanzo kukonzerwa nemamiriro anotevera: kudzvanywa kwechirimo kudiki, kusangana neoiri, tembiricha yezvakatipoteredza yakakwira zvakanyanya, kubata kweiyo yenguva refu yekushanda sisitimu, kushanda ikozvino kwakakurisa, zvichikonzera kubata. Kudimbura simba hakuna kukwana.Inogona kugadziriswa nekugadzirisa kusangana kwechitubu kudzvanywa, kuchenesa iyo yekubata kumeso, iyo contactor, uye kushandura iyo contactor ine yakakura kugona.
(3) Koiri inopisa uye inopiswa
Mamiriro ezvinhu anokonzerwa nekoil interturn short circuit, kana kana kushandiswa kweparameters uye kushandiswa kwemaitiro kunopesana, zvakadai seyero yakatemerwa uye iyo chaiyo yekushanda voltage haina kusangana.Kune zvakare mukana weiyo iron core mechanical block, mune iyi kesi, kubvisa iyo block error.
(4) The contactor haina kuvharwa pashure simba
Kazhinji, unogona kutarisa kana coil yatyoka kutanga.Panyaya yekutadza kwesimba, iyo multimeter inogona kushandiswa kuyera kana coil iri mukati meiyo yakatarwa.
(5) Kushaya kuyamwa
Kana magetsi emagetsi akanyanya kuderera kana kuchinja zvakanyanya, kana iyo yakatemerwa voltage yecoil pachayo yakakura kupfuura iyo chaiyo control redunhu voltage, kusveta kweiyo contactor kuchave kusina kukwana.Iyo voltage inogona kugadziridzwa kuti ienderane nayo neiyo chaiyo yakatarwa voltage yeiyo contactor.Panguva imwecheteyo, kana chikamu chinofambiswa checontactor chakavharwa, zvichiita kuti musimboti urereke, izvo zvinogona zvakare kutungamirira mukusakwana kusveta, chikamu chakanamira chinogona kubviswa uye kugadzirisa nzvimbo yepakati.Uye zvakare, iyo reaction simba chitubu yakakurisa, asi zvakare inogona kutungamira mukusakwana kusveta, kudikanwa kwekugadzirisa reaction simba chitubu.
(6) Mazita haagone kusetwa patsva
Chekutanga pane zvese, iwe unogona kuona kana iyo static uye static mabatirwo akasungwa pamwechete.Kana izvi zvikaitika, kazhinji unogona kupora nekutsiva vanobatika, uye zvakare tarisa kana paine chinhu chakanamira muzvikamu zvinofambiswa.
Chirevo: chinyorwa ichi zvemukati uye mapikicha kubva kunetiweki, kukanganisa, ndapota bata kuti udzime.
