Igihe cyo gukoresha insinga mu kabati ka PLC cyagabanutse cyane hamwe na pluggable 5.08mm Pitch DIN Rail Terminal Blocks — Icyo sosiyete zikora mu by'ikoranabuhanga zungukira mu gukora neza kw'inganda

Imiterere y'umurimo wa screw terminal wiring gakondo

Mu kabati gakomeye gapima PLC gakoreshwa mu gupakira imashini, sisitemu zo kohereza, cyangwa kugenzura imashini zikoresha inshinge, ubusanzwe haba hari imiyoboro y'insinga 600-1.200. Buri miyoboro ku gice gisanzwe cyo gushyiramo insinga bisaba: gukuraho 8-10mm z'ubushyuhe ku mpera y'insinga hakoreshejwe igikoresho cyo gukurura gikozwe mu buryo buhanitse, gushyiramo insinga yakuwemo mu mwanya wa terminal, gukaza screw ku muvuduko wagenwe (ubusanzwe 0.5-0.8 Nm kuri insinga ya 2.5mm² nk'uko byagenwe n'uwakoze terminal), no kugenzura isano hakoreshejwe ikizamini cyo gukurura nk'uko IEC 60947-7-1 yabivuze. Inzira yose yo kugenzura imiyoboro ifata amasegonda 45-90 kuri buri nsinga bitewe n'uburambe bw'umutekinisiye, uburyo aho terminal iri mu kabati gapakiye cyane, ndetse niba inzira y'insinga isaba izindi ntambwe zo gucunga insinga. Ku mpuzandengo y'amasegonda 60 kuri buri guhuza na 800 kuri buri kabati, imiyoboro y'insinga itaziguye yonyine ni iminota 800 - amasaha arenga 13 kuri buri kabati.

Ibi ntibikubiyemo igihe gisabwa kugira ngo umuntu asobanure igishushanyo mbonera cy’insinga no kugihuza n’aho icyuma giherereye. Imbonerahamwe y’insinga igaragaza imiyoboro y’ubwenge: "I0.0 → terminal X1:47." Umutekinisiye agomba gushaka terminal X1 kuri DIN rail, akabara kugeza ku mwanya wa 47 mu murongo w’imiyoboro isa 60-80, hanyuma agashyiramo insinga ikwiye. Ku bucucike bwa terminal 60 kuri metero imwe ya DIN rail, itandukaniro rigaragara hagati ya terminal 47 na terminal 48 risaba kwitabwaho cyane kuri buri ihuriro. Igipimo cy’amakosa mu gihe cy’umusaruro - aho abatekinisiye bashyiraho insinga mu masaha 7-8 kuri buri simburana - ni amakosa agera kuri 2-5 kuri buri kabati, hashingiwe ku makuru y’ubwiza bw’itsinda nasuzumye. Buri kosa rifata iminota 15-45 kugira ngo risuzumwe kandi rikosorwe mu gihe cyo gusuzuma no gukosora mu gihe cyo gusuzuma imikorere, hongerwaho iminota 30-225 yo gusubiramo kuri buri kabati. Aya makosa hafi ya yose ni imikorere y’intambwe yo gukora ikarita y’intoki - intoki z’umutekinisiye zaguye ku nsinga ikwiye ariko aho icyuma giherereye atari ho - kandi ntibishoboka kuyakuraho binyuze mu mahugurwa cyangwa gahunda yo gutunganya gusa.

Paradigm ishobora guhindurwa: Irangirira kuri Harness, ntabwo iri kuri Cabinet

Uduce tw’insinga dushobora gucomeka duhindura uburyo bw’ibanze bwo gufunga insinga kuva ku gusoza insinga kugeza ku gusoza insinga. Aho kuzana insinga mu kabati no kurangira buri imwe ku mwanya wayo wagenwe kuri rail ya DIN, icyuma gishyiraho panel cyakira imigozi y’insinga yateguwe mbere hamwe n’imigozi ishobora gucomeka yamaze gucomeka ku mpera z’insinga. Agace k’insinga - plaki ifite imyanya 2-24 ifite umuvuduko wa 5.08mm - ihuzwa n’umutwe udahinduka ushyizwe kuri rail ya DIN. Inshingano z’icyuma gishyiraho akabati zihinduka kuva ku gusoza insinga 800 zishyirwa ku murongo umwe zikajya ku gusoza 20-40 zishyirwa ku mutwe umwe mu migozi yazo.

Iyi ni icyitegererezo gitandukanye cyane cyo guteranya gifite ingaruka zirenze kure amafaranga yo kuzigama mu kazi. Imirimo yo guteranya insinga ikora neza cyane, ishobora no gukururwa n'amakosa yimurirwa mu cyiciro cyo gukora insinga, aho ishobora gukorerwa ku ntebe mu gihe cy'urumuri rwiza, hamwe n'uburyo bwo kugera ku maso y'insinga, kandi - mu buryo bw'umwihariko - hamwe n'ibikoresho byo gupima insinga byikora bigenzura buri sano ihuza, uburyo bwo gushyira pin neza, no kwirinda gushyushya mbere yuko insinga ijya mu iduka ry'insinga. Sisitemu yo gupima insinga ikoresha Cirris cyangwa ikindi gipimo cyikora gishobora kwemeza insinga y'insinga ifite imyanya 50 mu masegonda 30 kandi igatanga raporo y'ikizamini ikora nk'ikimenyetso cy'ubwiza bw'insinga ku igenzura ry'inganda z'insinga. Impinduka ni ukuva ku kwiringira uburyo tekiniki yitayeho ikagera ku kwiringira uburyo ibikoresho by'ikizamini bipima.

Igihe cyo kuzigama ni kinini kandi cyaragaragajwe neza mu nyubako z'inganda. Agasanduku k'umuhuza gafite insinga 12 zarangiye gashyirwa mu mutwe wa DIN mu masegonda 5-10 - igihe gisabwa kugira ngo umuhuza ahuze n'umutwe, akawushyiramo kugeza igihe agasanduku gafunga gakoze neza, kandi kemeze neza ko kashyizwemo neza ureba ko isura y'umuhuza ihuye n'isura y'umutwe. Agasanduku k'imirongo isanzwe ifite imyanya 12 gasaba iminota 12-18 kugira ngo karangire mu kabati. Uburyo bwo gucomeka bugabanya ibi kugeza ku masegonda ari munsi ya 30 ku mikorere y'uruhande rw'akabati - igabanuka rirenze 95% ry'imirimo y'uruhande rw'akabati kuri izo 12. Mu kabati k'imirongo 800 gafite imiyoboro icomeka, igihe cyo gucomeka ku ruhande rw'akabati kigabanuka kuva ku masaha 13+ kikagera ku masaha agera kuri 2-3. Igihe cyo gucomeka ku ruhande rw'akabati, gikorerwa ku ntebe, cyongeraho amasaha 4-6, kugira ngo hagabanuke 35-45% mu mikorere y'imirongo yose.

Gukuraho amakosa binyuze mu gufunga neza

Inyungu ikomeye cyane mu bukungu y’ibice by’imashini bishobora gucomekwaho ishobora kuba atari ukwizigamira kw’abakozi - ni ukugabanya amakosa yo gutanga insinga. Iyo uruganda rukora imigozi rwubatse umuyoboro w’impande 12 ufite insinga mu myanya ya 1 kugeza kuri 12, pinout iba ihamye. Imashini ikora imigozi ntishobora gushyira umugozi utari wo mu mwanya wa 7 kuko umugozi w’umwanya wa 7 uba wararangiye mu muyoboro w’imashini ku mwanya wa 7 kandi ntushobora kwimurwa utabanje gukata no kongera kuwuhagarika. Igikorwa cyonyine cyo guteranya mu kabati ni ugushyira umuyoboro mu mutwe ukwiye, wanditseho ikimenyetso cy’umuyoboro (urugero, "X101") uhuye n’igishushanyo cy’umuyoboro n’ikimenyetso cy’umubiri ku mubiri w’umuyoboro w’imashini.

Uku guhinduka kuva ku kugenzura kuri buri muyoboro kugeza ku kugenzura kuri buri muyoboro bihindura cyane cyane imiterere yo kubona amakosa. Mu kabati gasanzwe gakoresha insinga kuva ku gace kugera ku gace, buri muyoboro 800 ugomba gusuzumwa ukwawo ukurikije igishushanyo mbonera cy'insinga - inzira yo kugenzura isaba amasaha 4-6 kandi igenzurwa n'umuvuduko w'amakosa nk'uwakoreshejwe mbere. Hamwe n'abahuza bashobora gucomeka, kugenzura bigabanya kugeza kuri: (1) kwemeza ko umuyoboro wari ukomeje kandi ko pinout yapimwe ku ruganda rwakoraga umuyoboro kandi raporo y'ikizamini iraboneka, na (2) kwemeza ko buri muyoboro ucagagura uri mu mutwe ukwiye ureba neza icyapa ukurikije imiterere y'akabati. Intambwe ya 2 bifata iminota 10-15 ku bahuza 30. Imirimo yose yo kugenzura igabanuka kuva ku masaha 4-6 kugera munsi y'isaha imwe. Igipimo cy'amakosa yo gufunga insinga kigabanuka kuva kuri 2-5 kuri buri kabati kigera hafi ya zeru kuko pinout ishyirwa mu bikorwa n'umuhuza - nta cyemezo cy'umukoresha ku bijyanye n'insinga ijya aho ijya, gusa ni ukureba hagati y'ibirango bibiri.

Itsinda UL 508A ibipimo ngenderwaho ku mashini zigenzura imikorere y'inganda no IEC 61439 Ku bijyanye n'ibikoresho byo gusimbuza umuriro bifite voltage nke n'ibikoresho byo kugenzura, byombi ni ikoranabuhanga ryo guhuza ibikoresho bishobora gusimbuza umuriro nk'uburyo bwo kunoza ubwiza bw'insinga z'uruganda. UL 508A yemerera by'umwihariko ibikoresho bishobora gusimbuza umuriro nk'uburyo bwemewe bwo gusimbuza umuriro mu gihe igikoresho cyo gusimbuza umuriro kiri ku rutonde rw'ibikoresho bikoreshwa kandi ingano y'amashanyarazi/amashanyarazi iri mu bipimo by'uruganda rukora ibikoresho.

Umurimo wo mu murima: Aho inyungu iboneka yiyongera

Kuzigama igihe cyo guteranya bitanga impamvu yo gukoresha ibyuma bishobora gucomeka ku iduka ry’ibikoresho; kuzigama serivisi zo mu murima niho inyungu yihuta kurusha uko byari byitezwe mbere yo kugura. Iyo module ya I/O yangiritse mu kabati ka PLC gafite imiyoboro gakondo yo gukurura, inzira yo gukorera mu murima itwara igihe kinini: gufotora cyangwa gushyira ikimenyetso kuri buri nsinga ihujwe na module yangiritse (iminota 10-30, bitewe n’ubucucike bw’insinga n’ubwiza bw’imitako), gukuramo insinga zose 20-40 (iminota 5-15), gukuraho module yangiritse hanyuma ushyireho iyisimbura (iminota 5-10), kongera guhagarika insinga zose ku miyoboro ikwiye kuri module yo gusimbuza mu gihe ureba ifoto cyangwa ibirango byafashwe mu ntambwe ya 1 (iminota 20-45), no kugenzura buri guhuza (iminota 5-10). Igihe cyose cyarangiye: iminota 45-105 y’abakozi b’abahanga mu bya tekiniki, aho imashini ikora idakora.

Hamwe n'ibihuza bishobora gucomekwa, uburyo buhinduka: gukuramo agasanduku k'umuhuza kuri module yananiwe (amasegonda 5), ​​gukuramo module yananiwe hanyuma ugashyiraho iyisimbura (iminota 5-10), hanyuma ugashyira agasanduku k'umuhuza muri module yo gusimbuza (amasegonda 5). Insinga ntazo ziracomekwa. Insinga ntazo ziracomekwa. Guhuza ntazo bisaba kugenzura kuko umuhuza umwe ufite insinga zimwe mu myanya imwe y'uburinzi ubu uba wacomekwa muri module imwe yo gusimbuza. Igihe cyose - munsi y'iminota 10, gishingiye ku gusimbuza module ya mechanical no kongera gutangiza PLC - ni ukugabanuka kwa 80-90% ugereranije n'uburyo busanzwe. Mu nganda aho igihe cyo kudakora imashini gitwara hagati ya 500-5.000 USD ku isaha (imiyoboro y'imodoka, gupakira ibiryo n'ibinyobwa, gukora imiti, gukora semiconductor), itandukaniro riri hagati yo gusana iminota 90 no gusana iminota 10 rigabanya igiciro cya 650-7.500 USD mu gihe cyo kudakora kuri module ya I/O. Mu gihe cy'imyaka 10-15 imashini ikora, ikaba yasimbuwe module 3-6 za I/O, amafaranga azigamwa mu mirimo yo mu murima ashobora kurenza ikiguzi cyiyongereyeho cya pluggable terminal blocks inshuro 3-5.

Ubukungu bw'Ikiguzi cya Buri Muyoboro

Ku rwego rw'ibice, agace gasanzwe k'ibice bibiri gakoresha screw-clamp feed-through terminal block gagura hafi 0.30-0.60 USD kuri buri mwanya mu bwinshi (ahantu 5.000+). Sisitemu y'agace gakoresha 5.08mm gashobora gucomekwaho - kagizwe n'umutwe wa DIN rail-mounted na harness-side plug connector - gagura hafi 0.80-1.50 USD kuri buri mwanya. Igiciro cy'ibice ni igiciro cy'agaciro kiri hagati ya 0.50-1.00 USD kuri buri mwanya, aho ku kabati gakoresha imyanya 800 hagera kuri 400-800 USD mu giciro cy'inyongera cy'ibikoresho.

Ariko, ikiguzi cy'ibice ni ikintu kimwe gusa. Igipimo cy'abakozi bateranya ibikoresho byinshi ku iduka ry'ibikoresho muri Amerika ya Ruguru cyangwa Uburayi bw'Iburengerazuba ni hagati ya 35-55 USD ku isaha. Amafaranga azigamwa ku mukozi kuri buri muyoboro - hafi amasegonda 30-50 - ahinduka 0.29-0.76 USD kuri buri muyoboro kuri ibi bipimo. Hakoreshejwe ibice byo hagati bya buri cyiciro, amafaranga azigamwa ku mukozi ya 0.75 USD agabanywaho 0.50 USD mu mafaranga azigamwa ku mukozi, bigatuma amafaranga azigamwa ku mukozi ya 0.25 USD kuri buri mwanya - cyangwa 200 USD ku kabati kari ku myanya 800. Iyo amafaranga azigamwa ku mukozi, igihe cyo kugerageza imikorere kigabanuka, no gukuraho ibirego by'insinga z'ingwate, ikiguzi cyose cyo gutunga gihinduka cyane kigashyirwa ku isoko ry'ibikoresho bishobora gucomekwa ku mwaka wa 1-2 w'imirimo yo mu rugo.
