Imwe ndeyekutarisa kutadza kukuru kwezvakatipoteredza nekuenzanisa iyo chaiyo yekushandisa nharaunda (senge tembiricha, mhepo yekumanikidza, humidity, munyu pfapfaidzo, kukanganisa, vibration, kushandiswa kwekunze mamiriro azvino, kunyanya kubhadharisa-kuburitsa curve maitiro).Imwe ndeye kuongorora uye kuona kuumbwa kweiyo yakakosha chikamu zvinhu senge zvekubatikidza zvinhu, yekuonana nzvimbo yekugadzira nzvimbo uye mabhomba zvinhu, funga hunhu hwechinhu chechinhu kubva pakuona kwemukati, uye kusanganisa idzi data kuti uongorore chiyero chekutadza kwemashure. -kutengesa data.Muchokwadi, kune kunze kwekuvhiringidza zvinhu: zvinosanganisira akasiyana arc bin chimiro cheiyo contactor, chimiro chedhiraivha coil (ikozvino nhanho mbiri-coil chimiro) uye drive control mode, mutsauko wekunze dhiraivha redunhu, rimwe simba. -saving drive circuit.
Izvi ndizvo zvatinotsvaga uye kuunganidza data, tozounganidza.
Zvisinei, musiyano mukuru pakati contactor uye relay nhema ari disconnected mutoro mamiriro
Macontactor anoshandiswa kune mhando yemutoro ine yakakwira voltage, yakakwira ikozvino kana zvese.Kazhinji inoshandiswa kune midziyo ine anopfuura 15 amps kana 3kW.Kune huwandu hwakaderera, relay yakajairika inoshandiswa.
Ongorora: kutaura zvazviri, isu tinoshandisa contactor uye relay ndikowo kuona zvavanozvivaraidza nazvo, hautendi kuona mashandisiro anoita maJapan: preface yakanyorwa kudaro, iyi nhevedzano haisi contactor?
Kubva mukugadzirwa kwemumba kunonyanya kuve nemisiyano iyi, isu takasimba pfungwa kana kusiyanisa pazasi
1) Musiyano mune zvazvino unotungamirwa nekusangana
Kazhinji, mugadziri achapa fekitori kukosha kwekupikisa conduction, uye isu tichaongorora iyo yenguva refu yekudziya modhi yekusangana kwese zvinoenderana neichi kukosha.Iyi poindi inodawo kuti tinyatsoikurukura, ko iko kudziya chaiko kwekusangana?Iko kusangana kunokanganisa kupisa kweimba yekuchengetera zvinhu, kunyanya iyo yekunze chisimbiso chimiro?Saizi chaiyo yekuonana, zvinhu, uye mamiriro ekubata achave nemhedzisiro yakakura pane anotevera akafanana akazara maitiro.
Kana isu tikanyatso bvisa iyo contactor, ma contacts haasi madiki.Kunyangwe mamwe macontactor akapatsanurwa neakasiyana azvino uye akasiyana saizi yekubata, isu tinofanirwa kumisikidza dhatabhesi chaiyo munzvimbo ino, kusarudza masampula ekuchembera kwecoil = kuonana kuramba kutarisisa uye kubata tembiricha yekutarisa.
Contactor mutakuri
Relay mutakuri
Uku kupisa, kunyanya kana iyo yepamusoro yakavharidzirwa yekubatanidza impedance uye static yekubatanidza yekubatanidza impedance zvikamu zviviri zvekupisa.
2) Iyo contactor inoshongedzerwa nearc kudzvinyirira michina, asi iyo relay kazhinji haina.
Pakuremerwa kwemagetsi kwakanyanya, macurrents anogona kuyambuka nzvimbo dzekusangana kana switch yashandurwa.Kuvhundutsa kwemagetsi kunogona kukonzera kukuvadza kwakakura kunzvimbo yekubata, zvichikonzera kukanganisa kwenzvimbo kusati kwasvika hupenyu hwayo hwaitarisirwa.Pane yakaderera voltage ine relarelay.Ichi chakanyanya kutsanangurwa chinotarisa mutsauko mune hunhu hwekuzorora:
Mufananidzo 1. Zvinhu zvezvinhu zvekuonana zvinonyanya kukosha
The fragmentation diagram, uye kuchengetedzwa kwekuongorora kwe emergency electric mota power system, isu kune rumwe rutivi mukuparadzaniswa kwekufunga, tinofanirwa kurekodha zvakananga uye kufunga nezvekuchengetedzwa kwemotokari iyo nyika inoda chaizvo kuita kudaro, sekudhumhana, senge. voltage kudonha, tembiricha yakakwira zvakanyanya, isingakwanise kuburitsa simba senge thermal runaway conditions.
3) Musiyano pakati peiyo contactor uye relay ndiyo simba rinopedzwa mukugadzirisa conduction mamiriro
Iyo contactor inoda dhizaini yeactuator kushandura akakura mabatiro, nekudaro ichida yakakura kwazvo solenoid coil, iyo inoshandisa yakawanda ikozvino panguva yekutanga nekugadzirisa.Kusiyana neizvi, iyo madiki emagetsi mune relay iri nyore kushandura uye haidi yakawanda ikozvino.
