Muedzo werelayrelay Relay ndiyo yakakosha mudziyo wehungwaru prepaid magetsi mita. Hupenyu hwerelay hunosarudza hupenyu hwemamita emagetsi kune imwe nhanho. Kuita kwechigadzirwa kwakakosha zvikuru pakushanda kwehungwaru prepaid magetsi mita. Nekudaro, kune akawanda epamba uye ekunze relay vagadziri, ayo akasiyana zvakanyanya muhukuru hwekugadzira, tekinoroji level uye maitiro ekuita. Naizvozvo, vagadziri vemagetsi emagetsi vanofanirwa kuve neseti yemidziyo yekuona yakakwana kana vachiyedza uye nekusarudza relay kuti vaone kunaka kwemamita emagetsi. Panguva imwecheteyo, State Grid yakasimbisawo sampling yekuona kweiyo relay performance parameters mune smart magetsi metres, iyo inodawo inowirirana yekuona michina yekutarisa kunaka kwemamita emagetsi anogadzirwa nevagadziri vakasiyana. Nekudaro, michina yekuona yerelay haina kungova nechinhu chimwe chete chekuona, maitiro ekuona haagone kuve otomatiki, iyo data yekuona inoda kugadziridzwa uye kuongororwa nemaoko, uye mhedzisiro yekuona ine akasiyana siyana uye artificiality. Uyezve, kutaridzika kwekuona kwakaderera uye kuchengetedzwa hakugone kuvimbiswa [7]. Mumakore maviri apfuura, The State Grid zvishoma nezvishoma yakagadzirisa zvinodiwa zvemagetsi emamita emagetsi, yakagadzira zvakakosha indasitiri zviyero uye zvigadzirwa zvehunyanzvi, izvo zvinoisa mberi mamwe matambudziko ehunyanzvi ekuona relay parameter, sekuremedza nekudzima simba relay, switching maitiro bvunzo, etc. ye relay performance parameter bvunzo, zvinhu zvekuyedza zvinogona kukamurwa kuita mapoka maviri. Imwe ndeyeyedzo zvinhu zvisina mutoro wazvino, senge kukosha kwekuita, kubata kuramba uye hupenyu hwemakanika. Yechipiri ine zvinhu zvinorema zvekuyedza, senge voltage yekubata, hupenyu hwemagetsi, huwandu hwekuremedza.Zvinhu zvekuyedza zvikuru zvinounzwa muchidimbu sezvinotevera :(1) kukosha kwekuita. Voltage inodiwa pakushandisa relay. (2) Bata kuramba. Resistance value pakati pematanho maviri kana magetsi avharwa. (3) Upenyu hwemakanika. Mechanical zvikamu kana pasina kukuvara, nhamba yenguva iyo relay switch chiito. (4) Bata voltage. Kana magetsi ekubatanidza akavharwa, imwe mutoro ikozvino inoshandiswa mumagetsi ekubatanidza dunhu uye kukosha kwevheji pakati pevanobata. (5) Upenyu hwemagetsi. Kana iyo yakayerwa voltage ichiiswa kumigumo ese eiyo relay kutyaira coil uye yakayerwa inomira mutoro inoiswa muiyo yekubata loop, kutenderera kuri pasi pemazana mazana matatu paawa uye kutenderera kwebasa iri 1∶4, nguva dzakavimbika dzekushanda kweiyo relay. (6) Kuwanda kwehuwandu. Kana magetsi akayerwa akaiswa kumativi ose maviri ekoiri yekutyaira uye 1.5 nguva yekutakura yakatemerwa inoshandiswa mukubatanidza loop, nguva yakavimbika yekushanda kweiyo relay inogona kuwanikwa panguva yekushanda kwe (10 ± 1) nguva / min [7] .Marudzi, semuenzaniso, marudzi mazhinji akasiyana erelay, anogona kukamurwa nemagetsi ekuisa, kumhanyisa nguva, kutenderera, kutenderera, kutenderera kwezvino, relay. yebasa inogona kukamurwa kuita electromagnetic relay, induction type relay, magetsi relay, zvemagetsi relay, nezvimwe, zvinoenderana nechinangwa chinogona kukamurwa kuita relay relay, relay kuchengetedza, nezvimwewo, Zvinoenderana neiyo yekuisa shanduko fomu inogona kukamurwa kuita relay uye kuyerwa relay. [8] Ingave kana kwete relay inobva pakuvapo kana kusavapo kwekupinza, relay haishande kana pasina kupinza, relay chiito kana pane kuiswa, zvakadai sepakati relay, general relay, time relay, etc. relay, pressure relay, liquid level relay, etc.. [8]Electromagnetic relay Schematic diagram ye electromagnetic relay chimiro Mazhinji erelay anoshandiswa mukudzora maseketi marelay emagetsi. Electromagnetic relay ine hunhu hwechimiro chakareruka, mutengo wakaderera, kushanda kwakaringana uye kugadzirisa, diki yekusangana (kazhinji pazasi SA), nhamba huru yevanobatika uye isina mahombe uye ebetsero mapoinzi, hapana arc yekudzima mudziyo, diki saizi, nekukurumidza uye kwakaringana chiito, inonzwisisika kutonga, yakavimbika, zvichingodaro. Inoshandiswa zvakanyanya mu low-voltage control system. Anowanzo shandiswa emagetsi emagetsi anosanganisira azvino relay, voltage relay, yepakati relay uye akasiyana madiki madiki marelay. 8 Electromagnetic relays ane zvese DC uye AC. Voltage kana yazvino inowedzerwa kumigumo yese yecoil kugadzira magetsi emagetsi. Kana simba remagetsi remagetsi rakakura kupfuura simba rekuita remuchirimo, armature inodhonzwa kuita kuti iyo inowanzo kuvhurika uye inowanzovharwa macontacts afambe. Kana iyo voltage kana ikozvino yecoil inodonha kana kunyangarika, iyo armature inoburitswa uye iyo yekubata inogadziriswazve. [8] Thermal relay Thermal relay inonyanya kushandiswa kumidziyo yemagetsi (kunyanya mota) kudzivirira kuwanda. Thermal relay imhando yebasa rinoshandisa yazvino yekudziya musimboti wemagetsi emidziyo, iri padyo nemota inobvumira kuwandisa kwehunhu hwe inverse time hunhu, inonyanya kushandiswa pamwe chete neiyo contactor, inoshandiswa kune matatu-chikamu asynchronous mota yakawandisa uye chikamu chekutadza kudzivirira kweatatu-phase asynchronous mota mukushanda chaiko, inowanzo tarisana nekukonzerwa nemagetsi kana mekiniki zvikonzero zvakaita sekutadza kwepamusoro uye kutadza kwechikamu. Kana iyo pamusoro pemazuva ano isiri yakakomba, nguva yacho ipfupi, uye windings haipfuure inobvumirwa tembiricha inokwira, izvi pamusoro pezvino zvinobvumirwa; Kana iyo yakanyanyisa-ikozvino yakakomba uye inogara kwenguva yakareba, inomhanyisa kuchembera kuchembera kwemota uye kunyange kupisa mota. Naizvozvo, mudziyo wekudzivirira mota unofanirwa kumisikidzwa mumotokari wedunhu. Kune akawanda marudzi emidziyo yekudzivirira mota mukushandiswa kwakajairwa, uye inonyanya kuzivikanwa isimbi ndiro thermal relay. metal plate type thermal relay is three-phase, kune marudzi maviri ane uye asina phase break protection. [8]Time relay Nguva yekutenderera inoshandiswa pakudzora nguva mukudzora dunhu. Rudzi rwayo rwakanyanya, zvinoenderana nemusimboti wekuita unogona kukamurwa kuita electromagnetic mhando, mweya wekunyorovesa mhando, yemagetsi mhando uye yemagetsi mhando, zvinoenderana nekunonoka modhi inogona kukamurwa kuita kunonoka kwesimba uye kunonoka kunonoka kwesimba. Iyo mhepo yekunyorovesa nguva relay inoshandisa musimboti wekunyorovesa mhepo kuwana kunonoka kwenguva, iyo inoumbwa nemagetsi emagetsi, kunonoka michina uye yekubata system. Iyo electromagnetic michina yakananga-inobata kaviri E-mhando yesimbi musimboti, iyo yekubata sisitimu inoshandisa I-X5 micro switch, uye inononoka nzira inotora airbag damper. [8]kuvimbika1. Kufurira kwezvakatipoteredza pane relay kuvimbika: avhareji yenguva pakati pekutadza kwerelays inoshanda muGB uye SF ndiyo yepamusoro, inosvika 820,00h, nepo muNU nharaunda, inongova 600,00h. [9]2. Kupesvedzera kwemhando yegiredhi pane relay kuvimbika: kana A1 yemhando yegiredhi relay inosarudzwa, avhareji yenguva pakati pekutadza inogona kusvika 3660000h, nepo avhareji yenguva pakati pekutadza kweC-giredhi relays i110000, ine musiyano we33 nguva. Zvinogona kuoneka kuti giredhi remhando yerelays rine simba guru pakuvimbika kwavo kuita. [9] 3, pesvedzero pakuvimbika kweiyo relay contact form: relay contact form ichakanganisawo kuvimbika kwayo, kukanda kamwe chete kuvimbika kwerudzi rwerelay kwaive kwakakwira kupfuura nhamba yemhando yebanga rimwechete kaviri kukanda relay, kuvimbika kunoderedza zvishoma nezvishoma nekuwedzera kwenhamba yebanga panguva imwe chete, ndiyo nguva yepakati pakati pekutadza single-pole single-throw relay kaviri. [9]4. Kupesvedzera kwechimiro chechimiro pane relay kuvimbika: kune makumi maviri nemana emhando dzerelay chimiro, uye imwe neimwe mhando ine chekuita pakuvimbika kwayo. [9]5. Kurudziro yetembiricha pakuvimbika kwerelay: tembiricha yekushanda yerelay iri pakati -25 ℃ uye 70 ℃. Nekuwedzera kwekushisa, nguva yepakati pakati pekukundikana kwerelays inoderera zvishoma nezvishoma. [9]6. Pesvedzero yechiyero chekushanda pakuvimbika kwerelay: Nekuwedzera kwechiyero chekushanda kwerelay, nguva yeavhareji pakati pekutadza inongoratidza maitiro ekudzika. Nokudaro, kana dunhu rakagadzirwa richida kuti relay ishande pamwero wakanyanya, zvakakosha kunyatsoona relay panguva yekugadzirisa dunhu kuitira kuti inogona kuchinjwa munguva. [9]7. Kupesvedzera kwechiyero chemazuva ano pakuvimbika kwerelay: iyo inonzi ikozvino chiyero ndiyo chiyero chebasa rekushanda ikozvino relay kune yakatarwa mutoro ikozvino. Chiyero chemazuva ano chine simba guru pakuvimbika kwerelay, kunyanya kana chiyero chemazuva ano chiri chikuru kupfuura 0.1, nguva yepakati pakati pekukundikana inoderera nokukurumidza, apo kana chiyero chemazuva ano chiri pasi pe 0.1, nguva yepakati pakati pekukundikana inoramba yakafanana, saka mutoro une chiyero chepamusoro chemazuva ano chinofanira kusarudzwa mumagadzirirwo ematunhu kuderedza chiyero chemazuva ano. Nenzira iyi, kuvimbika kwerelay uye kunyange dunhu rose harizoderedzwa nekuda kwekushanduka kwekushanda ikozvino.
