Unofanira kudzora mota pasina kubatana zvakananga necircuit ine simba guru here? Haunzwisisi here A1, A2, L1, T1 kana dhayagiramu yekubatana? Contactor inogona kuparadzanisa control circuit kubva ku power circuit. Zvisinei, kana ukasarudza contactor isiriyo yemazuva ano, inogona kukonzera kupisa zvakanyanya, kunamira kwekubatana, kugumburwa, uye kunyange njodzi dzekuchengetedza.
Chii chinonzi Contactor mumagetsi?
Contactor iswichi inorema inoshandiswa nemagetsi inoshandiswa kubatanidza kana kubvisa macircuit emagetsi, kazhinji pakutakura zvinhu zvine simba guru semamota, mapombi, uye mwenje. Inoshanda ichishandisa coil ine simba shoma kugadzira munda wemagetsi unovhara macontact ane simba guru, zvichipa nzira yakachengeteka uye iri kure yekuchinja ma currents makuru.
Nheyo huru ye contactor yakafanana neye relay: kana load current yakakura zvakanyanya, hazvina kukodzera kushandisa switch yemaoko kana relay diki, contactor inofanira kushandiswa. Mashandisirwo akajairika anosanganisira:
- Mota dzemaphase matatu dziri mumapombi, mafeni, macompressor nemidziyo yekuendesa zvinhu
- compressor uye mota dzinofefetera mumasisitimu eHVAC
- Dunhu remwenje yekutengeserana
- Dunhu remagetsi rinodziya
- Kabhineti Yekudzora Midziyo Yemaindasitiri
- Kuchinja kwe capacitor uye kutonga kwekugovera
Sei switch yakajairika isina kukwana?
Maswichi ekushandisa mawoko anongogona kutakura magetsi akagadzirwa nemaoko chete, uye haakwanise kubata zvakanaka magetsi makuru anokonzerwa nemagetsi kana mota ichitanga kushanda nguva nenguva. Magetsi panguva yekutanga injini anowanzo svika kakawanda pane magetsi akagadzirwa nemotokari. Saka, dunhu rekudzora mota rakazara rinowanzo da kushandisa contactor, dziviriro ye overload uye dziviriro ye short-circuit .
Nzira iri nyore yekusarudza ndeyekuti: kudzora nhanho yechiratidzo kunogona kushandisa relay; asi kana mutoro uri wemagetsi akakwira, mutoro weinductive, mutoro wezvikamu zvitatu kana uchida kudzimwa kakawanda, contactor inofanira kushandiswa.
Ko Contactor Inoshanda Sei?
Nheyo yekushanda kwecontactor yakavakirwa pamhedzisiro yemagetsi. Kana voltage yekudzora ikashandiswa kuma terminals e coil akanyorwa A1 neA2, coil inogadzira simba remagineti. Simba remagineti rinokwezva armature, rinoita kuti contact inofamba uye static contact ivharwe, uye magetsi anogona kuyerera kubva kudivi remagetsi kuenda kudivi remutoro.
Mushure mekucheka voltage ye coil, simba remagineti rinonyangarika. Chitubu chekugadzirisa chinosundira zvikamu zvinofamba kudzokera kunzvimbo yekutanga, kubatana kwacho kunobviswa, uye simba remagetsi rinoenda kumutoro rinomira.
Mazhinji macontactor ane marudzi matatu ezviteshi zvakakosha kana mapoka ekubatana:
- Makoira emagetsi: A1 neA2 anoshandiswa kuwana voltage yekudzora.
- Materminations makuru emagetsi: L1, L2, L3 ndiwo materminations emagetsi; t1, T2 naT3 ndiwo magumo ekubuditsa magetsi.
- Masangano ekubatsira anosanganisira macontacts anowanzo vhurwa (NO) kana macontacts anowanzo vharwa (NC), ayo anoshandiswa kuita feedback, interlock, indication kana self-sustaining control logic.
Chinobatidza AC neChinobatidza DC: Ungasarudza Sei?
Kusarudza contactor kunoenderana nerudzi rwemutoro, simba remagetsi, voltage, simba remagetsi, mashandiro ekutonga, mafrequency ekushanda uye hupenyu hwemagetsi.
Macontactor eAC anoshandiswa mumasekete eAC, anowanzo shandiswa mukutonga mota, mumidziyo yeHVAC, mapombi, mafeni uye masisitimu emwenje. DC contactor inoshandiswa kumasekete eDC. AC current inoyambuka zero nguva nenguva, nepo DC current isingadaro. Nekuda kweizvozvo, arc inogadzirwa muDC circuit inonyanya kuoma kudzima, zvichiita kuti dhizaini yekudzima arc iwedzere kudiwa.
Kana mutoro uri wemota yeAC kana mutoro wekugovera weAC, contactor yeAC inofanira kusarudzwa. Kana mutoro uri weDC system, senge mabhatiri, DC control circuit, system ine chekuita nephotovoltaic kana michina mitsva yesimba, contactor yeDC inofanira kusarudzwa.
AC-1, AC-3 uye AC-4 zvakakosha
Mudziyo wakakodzera haufanirwe kungoenderana nemutengo wezvino chete. Kugona kwekutakura kwezvishandiso zve contactors zvine simba rakafanana kunogona kusiyana zvakanyanya pasi pemhando dzakasiyana dzekushandiswa.
- AC-1: yakakodzera mitoro inodzivisa kupisa senge macircuit ekupisa.
- AC-3: yakakodzera kutanga nekudzima mota ine keji yesquirrel kana mota yasvika pakumhanya kwakajairika.
- AC-4: yakakodzera mamiriro ekushanda akadai sekudzvanya, kubhureka kwemashure, kumira-mira kakawanda kana kutenderera zvakanaka nezvakaipa, uye mamiriro acho akaomarara.
Kana michina ichida kutanga nekumisa mota nguva nenguva kana kuchinja chinotungamira nguva nenguva, contactor inofanira kusarudzwa zvichienderana nemamiriro chaiwo ekushanda. Zvikasadaro, kupedzwa kwecontact kuchakurumidza uye hupenyu hwebasa huchapfupikiswa zvakanyanya.
Dhiagiramu yeContactor: Unganzwisisa sei Terminal neControl Circuit?
Dhayagiramu yekutanga yekubata inowanzo miririra tambo yesimba uye tambo yekudzora zvakasiyana.
Dunhu remagetsi riri nyore:
- L1, L2, L3: chiteshi chemagetsi
- T1, T2, T3: chiteshi chekuburitsa zvinhu (load outgoing terminal)
- Mota kana mutoro: zvakabatana mushure meT1, T2, T3
Chinotenderera chinoratidza pfungwa yekudzora:
- A1 neA2: materminal ekoira
- Bhatani rekutanga: Bhatani rekudzvanya rakajairika (rinowanzo vhura bhatani rekudzvanya)
- Bhatani rekumisa: bhatani rekudzvanya rinowanzo vharwa.
- Kubatsira KUSAVA nekubata: kwezvinotsigira loop
- Kubatanidza NC relay relay: Bvisa coil circuit kana yakawandisa
Dunhu rekudzora rekutanga/kumisa rinoshanda seizvi: Mushure mekudzvanya bhatani rekutanga reSTART, coil inowedzerwa simba, contact huru inovharwa, uye contact inobatsira inowanzo vhurwa inovharwawo. Assistant contact inoramba ichichengetedza coil ichishanda mushure mekusunungura bhatani reSTART, zvichiita loop inozvitsigira. Mushure mekudzvanya bhatani reSTOP, control loop inobviswa, coil inorasikirwa nesimba, contactor inosunungurwa, uye mutoro unomira kushanda.
Chiyeuchidzo chekuchengetedza: dhayagiramu yekubatanidza haigone kutsiva maitiro ekukodzera uye ekuchengetedza ari panzvimbo yacho. Kuisa, kuyedza nekugadzirisa kunofanirwa kuitwa nevashandi vemagetsi vane hunyanzvi, uye kutevedzera zvinodiwa nemagetsi emunharaunda uye zvinodiwa zvekukiya/kuburitsa magetsi.

mhedziso
Iyo contactor inobvumira masaini ekudzora ane simba shoma kudzora zvakachengeteka uye kazhinji mitoro ine simba guru. Paunosarudza contactor, rudzi rwesystem yeAC kana DC, zvinodiwa zve load current, coil voltage, rudzi rwekushandisa, wiring diagram uye zvinodiwa zvemudziyo wekudzivirira zvinofanirwa kusimbiswa. Kana uine mibvunzo nezve parameters, ndapota taura nechikwata cheTomzn.
Chii musiyano uripo pakati peAC contactor neDC contactor?
Iyo AC contactor yakakodzera AC load, uye AC current inoyambuka zero nguva nenguva, izvo zvinobatsira kudzima arc. DC contactor yakakodzera DC load, uye DC arc inonetsa kuputsa, saka kugona kwayo kudzima arc kunoda zvakawanda. Pakusarudza, voltage yesystem, load current uye current type zvinofanirwa kuenzaniswa.
Chii musiyano uripo pakati pecontactor nerelay?
Relay inowanzo shandiswa kune chiratidzo chidiki chesimba kana dunhu rekudzora, uye contactor inoshandiswa kune dunhu remagetsi rine magetsi makuru. Contactor ine chimiro chakasimba chekubata, kugona kudzima arc uye inochinjika kune mutoro wemota wezvikamu zvitatu. Relay inogona kusarudzwa kune kudzora chiratidzo chidiki, uye contactor inofanira kusarudzwa kune mutoro wemota.
Ko contactor inodzivirira mota kubva pakuzara kwemafuta here?
Haikwanise kudzivirirwa yoga. Contactor inongoshanda chete pakubatidza nekupwanya mota, uye dziviriro yekuwedzeredza inowanzoitwa ne thermal overload relay, motor protection circuit breaker kana zvimwe zvishandiso zvekudzivirira. Motor starter inowanzo gadzirwa ne contactor uye overload protection, uye inoshanda pamwe chete ne short-circuit protection device yepamusoro.
Nzira yekunzwisisa sei dhayagiramu yekuonana?
Zvakakosha kutanga wasiyanisa dunhu remagetsi nedunhu rekudzora. L1, L2 naL3 ndiwo materminal emagetsi anopinza magetsi, T1, T2 naT3 zvakabatana nemutoro, uye A1 naA2 ndiwo materminal ecoil. Macontact ekubatsira anoshandiswa kuita mabasa ekudzora akadai semhinduro, interlocking, indication kana self-holding. Data sheet yechigadzirwa inofanira kuongororwa usati waisa waya chaiyo.
Ko contactor inogona kushandiswa sechinodzima chinja here?
Kwete. Chinobatisa chinogona kutyora circuit yemutoro panguva yekushanda kwakajairika, asi hachigone kushandiswa semudziyo mukuru wekuparadzanisa simba panguva yekugadzirisa. Kuchengetedzwa kwekuchengetedza kunofanirwa kushandisa zvinodzikisa kana zvinopwanya circuit zvinoenderana nezvinodiwa, uye kuita maitiro ekukiya/kuburitsa tagout sezvinodiwa.
