Nthawi Yolumikizira Ma Wiring a Makabati a PLC Yatsika Kwambiri Ndi Ma Block a 5.08mm Pitch DIN Rail Terminal Blocks Otha Kulumikizidwa — Zomwe Ma OEM Oyendetsa Mafakitale Amapeza Pakugwira Ntchito Bwino kwa Msonkhano

Zomwe Zili mu Ntchito ya Traditional Screw Terminal Wiring

Mu kabati yowongolera ya PLC yovuta kwambiri yopangira makina opakira, makina otumizira, kapena makina owongolera jakisoni, nthawi zambiri pamakhala ma waya okwana 600-1,200. Kuchotsa kulikonse pa bolodi lachikhalidwe lolowera kudzera pa terminal kumafuna: kuchotsa 8-10mm ya insulation kuchokera kumapeto kwa waya pogwiritsa ntchito chida chowongolera chokhazikika, kuyika waya wodulidwa mu terminal potseguka, kumangirira screw ku torque yodziwika (nthawi zambiri 0.5-0.8 Nm ya waya wa 2.5mm² monga momwe wopanga terminal adanenera), ndikutsimikizira kulumikizana ndi mayeso okoka malinga ndi IEC 60947-7-1. Kuzungulira konse kwa strip-insert-tighten-verify kumatenga masekondi 45-90 pa waya kutengera zomwe katswiri waluso akumana nazo, kupezeka kwa malo a terminal mkati mwa kabati yodzaza kwambiri, komanso ngati njira yolumikizira waya ikufunika njira zina zowongolera chingwe. Pa avareji ya masekondi 60 pa kulumikizana ndi ma 800 pa kabati, ntchito yolumikizira mwachindunji yokha ndi mphindi 800 - kupitirira maola 13 pa kabati iliyonse.

Izi sizikuphatikizapo nthawi yofunikira kutanthauzira chithunzi cha mawaya ndikuchiyika pamalo enieni a terminal. Chithunzi cha mawaya chikuwonetsa kulumikizana kolondola: "I0.0 → terminal X1:47." Katswiri ayenera kupeza terminal X1 pa DIN rail, kuwerengera mpaka malo 47 pamzere wa ma terminal 60-80 ofanana, ndikuyika waya woyenera. Pa kuchuluka kwa ma terminal 60 pa mita imodzi ya DIN rail, kusiyana kowoneka pakati pa terminal 47 ndi terminal 48 kumafuna chidwi chachikulu pa kulumikizana kulikonse. Kuchuluka kwa zolakwika pansi pa mikhalidwe yopangira - komwe akatswiri amalumikiza makabati kwa maola 7-8 pa shift iliyonse - ndi pafupifupi zolakwika za mawaya 2-5 pa kabati iliyonse pa avareji, kutengera deta ya khalidwe la panel shop yomwe ndayang'ana. Cholakwika chilichonse chimatenga mphindi 15-45 kuti chizindikire ndikukonza panthawi yoyesa magwiridwe antchito, ndikuwonjezera mphindi 30-225 za nthawi yokonzanso pa kabati iliyonse. Zolakwika izi pafupifupi zonse ndi ntchito ya gawo la mapu amanja - zala za katswiriyo zidagwera pa waya wolondola koma malo olakwika a terminal - ndipo sizingatheke kuzichotsa kudzera mu maphunziro kapena njira yokhayo.

Paradigm Yosinthika: Kutha pa Harness, Osati pa Cabinet

Ma block a terminal omwe amalumikizidwa amasintha njira yoyambira yolumikizira mawaya kuchokera ku terminal-in-cabinet kupita ku terminal-at-harness. M'malo mobweretsa mawaya amodzi mu kabati ndikumaliza chilichonse pamalo ake olumikizira pa DIN rail, womanga ma panel amalandira mawaya olumikizidwa kale okhala ndi zolumikizira zolumikizidwa kale zomwe zimalumikizidwa kumapeto kwa waya. Cholumikizira block - pulagi ya malo 2-24 yokhala ndi 5.08mm pitch - imagwirizana ndi mutu wokhazikika woyikidwa pa DIN rail. Ntchito ya womanga makabati imasintha kuchoka pa 800 ma terminal a waya amodzi kupita ku 20-40 ma connector blocks omwe amalumikizidwa kale m'ma header awo ofanana.

Iyi ndi njira yosiyana kwambiri yosonkhanitsira yomwe ili ndi zotsatira zomwe zimapitirira kupitirira ndalama zomwe zimagwiritsidwa ntchito mwachindunji. Ntchito yolumikiza mawaya yolondola kwambiri, yomwe imachitika chifukwa cha zolakwika imasunthidwa kupita ku gawo lopangira ma harness, komwe ingachitike pa benchi pansi pa mikhalidwe yabwino yowunikira, ndi mwayi wofikira mosavuta kumaso olumikizira, ndipo - mozama - ndi zida zoyesera ma harness zomwe zimatsimikizira kulumikizana kulikonse kuti kukhale kolondola, kugawa ma pin molondola, komanso kukana kutenthetsa ma harness asanatumizidwe ku shopu ya panel. Dongosolo loyesera ma harness pogwiritsa ntchito Cirris kapena tester yofanana nayo imatha kutsimikizira kusonkhana kwa cholumikizira cha malo 50 mkati mwa masekondi 30 ndikupanga lipoti loyesa lomwe limakhala umboni wabwino kwambiri wa kuwunika komwe kukubwera kwa shopu ya panel. Kusinthaku kukuchokera pakukhulupirira chidwi cha katswiri kupita kukukhulupirira muyeso wa cholinga cha zida zoyesera.

Kusunga nthawi n’kochuluka ndipo kwalembedwa bwino m’nyumba zamafakitale. Chipika cholumikizira chokhala ndi mawaya 12 otha kale chimalumikizidwa mu DIN rail header yake mu masekondi 5-10 - nthawi yomwe imafunika kuti cholumikiziracho chigwirizane ndi mutu, kuchikankhira mkati mpaka tabu yotseka igwire ntchito ndi kudina komveka, ndikutsimikizira bwino kuyika kwake poyang'ana kuti nkhope ya cholumikizirayo ili yosalala ndi nkhope ya mutu. Chipika cha screw terminal chachikhalidwe chokhala ndi malo 12 chimatenga mphindi 12-18 kuti chithe mu kabati. Njira yolumikizira imachepetsa izi kukhala zosakwana masekondi 30 kuti kabati igwire ntchito mbali - kuchepetsa kwakukulu kuposa 95% kwa ntchito mbali ya kabati pa zolumikizira 12 zimenezo. Pa kabati yolumikizira 800 yokhala ndi zolumikizira zotha kutha, nthawi yolumikizira mbali ya kabati imatsika kuchoka pa maola 13+ kufika pafupifupi maola 2-3. Nthawi yolumikizira mawaya otha, yomwe imachitidwa pa benchi, imawonjezera maola 4-6, kuti ichepetse ndi 35-45% ya ntchito yonse yolumikizira.

Kuchotsa Zolakwika Kudzera mu Pinout Yokhazikika

Phindu lalikulu kwambiri la ma terminal blocks otha kulumikizidwa silingakhale ndalama zomwe zimasungidwa pantchito - ndi kuchotsedwa kwa zolakwika zogawa mawaya. Wopanga ma harness akamanga cholumikizira cha malo 12 chokhala ndi mawaya m'malo 1 mpaka 12, pinout imakhazikika. Womanga panel sangaike waya wolakwika pamalo 7 chifukwa waya wa malo 7 watha kale mu cholumikizira pamalo 7 ndipo sungasunthidwe popanda kudula ndikuzimitsanso. Chokhacho chomwe chimachitika mu kabati ndikulumikiza cholumikiziracho mu mutu woyenera, womwe uli ndi chizindikiro cholumikizira (monga "X101") chomwe chikugwirizana ndi chithunzi cha mawaya ndi chizindikiro chenicheni pa thupi la cholumikizira cha mbali ya harness.

Kusintha kumeneku kuchokera pa kutsimikizira waya kupita ku kutsimikizira cholumikizira chilichonse kumasintha kwambiri mbiri yozindikira zolakwika. Mu kabati yachikhalidwe yolumikizidwa ndi waya, kulumikizana kulikonse kwa 800 kuyenera kufufuzidwa payekhapayekha motsutsana ndi chithunzi cha waya - njira yotsimikizira yomwe imatenga maola 4-6 ndipo imatengera kuchuluka kofanana kwa zolakwika za anthu monga mawaya oyamba. Ndi zolumikizira zolumikizidwa, kutsimikizira kumachepetsa kufika pa: (1) kutsimikizira kuti harness inali yopitilira ndipo pinout idayesedwa kwa wopanga harness ndipo lipoti loyesa likupezeka, ndi (2) kutsimikizira kuti pulagi iliyonse yolumikizira ili pamutu wolondola poyang'ana chizindikirocho motsutsana ndi chithunzi cha kapangidwe ka kabati. Gawo lachiwiri limatenga mphindi 10-15 kwa zolumikizira 30. Ntchito yonse yotsimikizira imatsika kuchokera maola 4-6 mpaka ola limodzi. Kuchuluka kwa zolakwika za waya kumatsika kuchoka pa 2-5 pa kabati mpaka pafupifupi zero chifukwa pinout imayendetsedwa ndi cholumikizira - palibe chisankho cha wogwiritsa ntchito chokhudza waya uti womwe umapita, koma kulumikizana kowoneka pakati pa zilembo ziwiri.
