Multi-level terminal blocks inogona kukurumidza kuisirwa uye kuchengetedza nzvimbo, ichitora iyo yekubatanidza kusvika padanho repamusoro

Chero magetsi kana magetsi control panel angada wiring.Kunyangwe iyo application iri yemidziyo yevatengi, midziyo yekutengesa, kana masisitimu emaindasitiri, vagadziri vanofanirwa kusarudza zvigadzirwa zvakavimbika zviri nyore kuisa uye zvinogona kushanda zvakavimbika kwemakore mazhinji.Terminal blocks inosangana nezvinodiwa izvi uye ndiyo yakajairika nzira yekubatanidza magetsi emunda mitsetse ine mapaneru-akaiswa emagetsi uye emagetsi masisitimu.
Iyo yakajairika uye yechinyakare screw-type single-layer terminal mhinduro iri nyore, asi haisi iyo nguva dzose inonyanya kushandisa nzvimbo kana yebasa.Kunyanya kana vanhu vachifunga kuti waya dzakawanda dzakaiswa muchimiro cheanoshanda maviri kana matatu-waya mapoka, akawanda-level zviteshi zviri pachena zvine dhizaini zvakanakira.Pamusoro pezvo, michina mitsva yemhando yechirimo inovimbika uye iri nyore kuisa pane zvigadzirwa zvemhando yescrew.Paunenge uchisarudza zvivharo zvekupedzisira kune chero application, vagadziri vanofanirwa kufunga nezvemafomu maficha uye humwe hunhu hwechigadzirwa kuti vawane kuita kwakanyanya.

Ruzivo rwekutanga rwematerminal blocks
Iyo yekutanga terminal block ine insulating shell (kazhinji imwe fomu yepurasitiki), iyo inogona kuiswa pane yeDIN njanji inoenderana neindasitiri zviyero kana yakananga bhoti kune yekumashure ndiro mukati megoko.Kune compact DIN terminal blocks, iyo imba inowanzovhurika kune rimwe divi.Aya mabhuroki akagadzirirwa kurongedzerwa pamwechete kuti awedzere kuchengetedza nzvimbo, uye mugumo mumwe chete westack unoda end cap (Mufananidzo 1).

1. Iyo DIN-mhando stackable terminal block inzira yakabatana uye yakavimbika yeindasitiri-giredhi wiring connections.
"Feedthrough" materminals anowanzo aine waya yekubatanidza poindi padivi rega rega, uye conductive strip pakati peaya mapoinzi maviri.Traditional terminal blocks inogona kungobata dunhu rimwe chete, asi zvigadziriso zvitsva zvinogona kuva nemazinga akati wandei uye zvinogona kusanganisira zviri nyore tambo dzekudzivirira tambo dzepasi.
Iyo yekirasi waya yekubatanidza poindi screw, uye dzimwe nguva washer inoshandiswa.Waya inoda kucheka mhete kana U-yakaita saga kumagumo, wobva waiisa uye woisimbisa pasi pe screw.Iyo imwe dhizaini inosanganisa screw yekubatanidza kweiyo terminal block mucage clamp, kuitira kuti tambo isina chinhu kana waya ine nyore cylindrical ferrule yakashongedzwa kumagumo inogona kuiswa yakananga mucage clamp uye yakagadziriswa.
Iyo ichangoburwa budiriro ndiyo chitubu-yakatakura yekubatanidza poindi, iyo inobvisa zvachose screws.Magadzirirwo ekutanga aida kushandiswa kwechishandiso chekusundira chitubu pasi, icho chaizovhura nzvimbo yekubatanidza kuitira kuti waya igopinzwa.Chitubu dhizaini haingobvumiri kukurumidza kukurumidza kupfuura yakajairwa screw-mhando zvikamu, asi iyo inogara ichitsikirira yechirimo inopikisa vibration zvirinani pane screw-mhando terminals.
Kuvandudzwa kweiyi dhizaini keji yechirimo inonzi push-in dhizaini (PID), iyo inobvumira waya dzakasimba kana ferrule crimped waya kuti dzisundirwe zvakananga mubhokisi rejunction pasina maturusi.Kune PID terminal blocks, maturusi akareruka anogona kushandiswa kusunungura waya kana kuisa isina tambo dzakasungwa.Iyo chitubu-yakarodha dhizaini inogona kuderedza wiring basa neinosvika 50%.
Kune zvakare zvimwe zvakajairika uye zvinobatsira terminal accessories.Iyo plug-in bridging bar inogona kuiswa nekukurumidza, uye akawanda materminal anogona kuchinjika-akabatana panguva, achipa compact simba rekugovera nzira.Mitemo yekumaka yakakosha kuti ipe pachena chiziviso chega chega terminal block conductor, uye spacers inobvumira vagadziri kuti vape yakakosha nzira yekuparadzanisa imwe kana anopfuura mabhuraki ekupedzisira kubva kune mumwe.Mamwe mablock block anobatanidza fuse kana kubvisa mudziyo mukati meiyo terminal block, saka hapana zvimwe zvikamu zvinodiwa kuita basa iri.
Ramba uchiita mapoka ematunhu
Zvekudzora uye otomatiki mapaneru, magetsi ekugovera maseketi (angave 24 V DC kana anosvika 240 V AC) anowanzoda waya mbiri.Masignal applications, akadai sekubatanidza kune ma sensors, anowanzo 2-waya kana 3-waya, uye angangoda mamwe analogi chiratidzo chenhoo yekubatanidza.
Ehe, ese aya wiring anogona kuisirwa pane akawanda-layer terminals.Nekudaro, kurongedza zvese zvinongedzo zvedunhu rakapihwa mune akawanda-level junction bhokisi kune akawanda ekutanga uye anoenderera mberi mabhenefiti (Mufananidzo 2).

2. Dinkle DP series terminal blocks inopa hukuru hwakasiyana hwe-single-layer, maviri-layer uye matatu-layer shapes.
Iwo akawanda maconductor anoumba dunhu, kunyanya masaini eanalogi, anowanzo mhanya mune akawanda-conductor tambo, kwete seakaparadzana makondakita.Nekuti ivo vakatosanganiswa mune imwe tambo, zvine musoro kumisa ese aya ane hukama makondakita kune imwe yakawanda-level terminal pane akati wandei-level terminals.Multi-level terminals inogona kukurumidzira kuisirwa, uye nekuti ese maconductor ari padhuze, vashandi vanogona nyore kugadzirisa chero matambudziko (Mufananidzo 3)

3. Vagadziri vanogona kusarudza akanakisa terminal blocks kune ese maficha ekushandisa kwavo.Multi-level terminal blocks inogona kuchengetedza yakawanda yekudzora pani nzvimbo uye kuita kuti kuisirwa uye kugadzirisa matambudziko kuve nyore.
Imwe inogoneka kusavimbika kwema-multi-level terminals ndeyekuti idiki zvakanyanya kushanda nemaconductor akawanda anobatanidzwa.Chero bedzi zviyero zvemuviri zvakaenzana uye mirau yekumaka yakajeka, mabhenefiti epamusoro wiring density achaiswa pamberi.Kune yakajairwa 2.5mm 2 saizi terminal, ukobvu hwese-matatu-nhanho terminal inogona kungove 5.1mm, asi 6 conductor inogona kugumiswa, izvo zvinochengetedza 66% yenzvimbo yakakosha yepaneru yekutonga zvichienzaniswa nekushandisa imwe-level terminal.
Grounding kana inogona kuitika pasi (PE) yekubatanidza ndeimwe kufunga.Kana ichishandiswa neyakavharidzirwa-yepakati-yechiratidzo tambo, iyo matatu-layer terminal ine kuburikidza nekondukita pazvikamu zviviri zvepamusoro uye PE yekubatanidza pazasi, iyo iri nyore kumhara tambo, uye inova nechokwadi chekuti shielding layer yakabatana kune DIN pasi njanji uye kabati.Panyaya yekubatana kwepamusoro-density yepasi, bhokisi rematanho maviri ane PE connections pamativi ose anogona kupa hutano hwakanyanya hwepasi munzvimbo duku kudarika.
Akapasa bvunzo
Vagadziri vanoshanda pakutsanangura zvivharo zvekupedzisira vanozoona kuti zviri nani kusarudza kubva kune huwandu hwezvigadzirwa zvinopa huwandu hwakakwana hwehukuru uye zvigadziriso zvinosangana nezvavanoda.Mabhuroko eindasitiri yemaindasitiri anofanirwa kuverengerwa kusvika pa600 V uye 82 A, uye anotambira saizi dzewaya kubva pa20 AWG kusvika 4 AWG.Kana iyo terminal block ikashandiswa mune control panel yakanyorwa neUL, inotenderwa neUL.
Iyo insulating enclosure inofanirwa kunge isingaite moto kuti isangane neUL 94 V0 yakajairwa uye ichipa kupikisa tembiricha pamusoro pehupamhi hwe -40 ° C kusvika 120 ° C (Mufananidzo 4).Iyo conductive element inofanirwa kugadzirwa nemhangura tsvuku (mhangura yemukati ndeye 99.99%) yeakanakisa conductivity uye kushoma tembiricha kukwira.

4. The test terminal yakakwirira kudarika indasitiri chiyero kuti ive nechokwadi chekushanda kwepamusoro uye yepamusoro.
Hunhu hwezvigadzirwa zvekupedzisira hunovimbiswa nemutengesi achishandisa zvivakwa zvemurabhoritari zvakapfuura UL uye VDE chapupu kuyedzwa uye chitupa.Wiring tekinoroji uye zvigadzirwa zvekumisa zvinofanirwa kuyedzwa zvakanyanya zvinoenderana neUL 1059 uye IEC 60947-7 zviyero.Miedzo iyi inogona kusanganisira kuisa chigadzirwa muchoto pa 70 ° C kusvika 105 ° C kwemaawa manomwe kusvika kumazuva manomwe zvichienderana nekuedzwa, uye kusimbisa kuti kupisa hakuzokonzere kuputika, kupfava, deformation kana kunyungudika.Kwete chete chimiro chemuviri chinofanira kuchengetedzwa, asiwo maitiro emagetsi anofanira kuchengetedzwa.Imwe yakakosha bvunzo yakatevedzana inoshandisa akasiyana marudzi uye nguva yemunyu wekupfapfaidza kuona kureba kwenguva refu kwekupokana kwezvigadzirwa.
Vamwe vagadziri vakatopfuura zviyero zveindasitiri uye vakagadzira kukurumidza kuyedza mamiriro ekunze kutevedzera mamiriro akaoma uye kusimbisa hupenyu hurefu hwechigadzirwa.Ivo vanosarudza yepamusoro-inoshanda zvinhu zvakaita sePA66 plastiki, uye vakaunganidza ruzivo rwakadzama mune yakakwirira-chaiyo jekiseni yekuumba maitiro ekudzora ese akasiyana uye kusangana nevanopedzisa zvinodiwa nevashandisi vezvigadzirwa zviduku zvinochengeta zviyero zvese.
Magetsi terminal mabhuroko chinhu chakakosha, asi anofanirwa kutariswa nekuti anoumba huru yekuisa interface yemidziyo yemagetsi nemawaya.Yakajairwa screw-type terminals inozivikanwa zvakare.Tekinoroji dzepamberi senge PID uye akawanda-level terminal mabhuroko anoita dhizaini, kugadzira, uye sevhisi michina nekukurumidza uye nyore, uku ichichengetedza yakawanda yakakosha yekudzora nzvimbo yenzvimbo.
