Iitheminali ezintambo kokuxhuma: esijijwayo, ukwabiwa, amandla

Vula njani uqhagamshelwano lombane ixesha elide kwaye zithembeke ixhomekeke ngokukhuseleka nokusebenza kwalo kufuneka elide. unxibelelwano phakathi kwala macingo anike isekethe ombane ezinzileyo anencasa ngaphandle ukweqa. Kodwa ke ukuba ngamanye amaxesha uyakwazi ukufumana ukujiwuza njengesiqhelo, kwiimeko ezininzi, le ndlela alwamkelekanga, kwaye kuyimfuneko ukuba usebenzise iitheminali zendibaniso nokufakelwa. "Kutheni?" - ubuze. Kodwa nantsi eyona nyaniso.

I-terminal block kungcono bajije?

ugesi abaninzi, ekukhoyo kuzo kakhulu kukho iingcali abaqeqeshiweyo nabanamava, bathi ngaphezu ikama - le twist njengesiqhelo. Oku kuyinyaniso, kodwa inxenye kuphela. Inyaniso kukuba oku kuxhomekeke izixhobo ngayo sisebenzisana kunye nezinto apho wenza ucingo ukuqhagamshela, kunye nezinye izinto. Oku xa uqala lingakhangeleka akwazuza, kodwa ke eneneni eyahlukileyo kancinci.

Ukuze sibale omnye okunika umdla. Imigaqo ephathelene umsebenzi siyavuma ukuba twist kuzo zonke kwamalungu akuvumelekanga. Ngenxa yesi sizathu elula, nayiphi na intlekele eyenzeka ngenxa yokuba uye wasebenzisa uqhagamshelo akuvumelekanga eyenzekayo na ityala lakho. Ukongeza, le imithetho yoFakelo Electrical (PUE) ukuba zonke iintlobo 4 iikhompawundi, ezinye zazo siza kuxubusha ngayo kweli nqaku.

Yintoni na block yesiphelo?

Yesiphelo - isixhobo okhethekileyo, nto leyo terminal Screw okanye ibhloko. It isetyenziselwa uqhagamshelo olukhuselekileyo of macingo. Kukho iindidi kunye ubukhulu bamanqatha mihla abaninzi. Kodwa kubalulekile ukuphawula ukuba kwiitheminali loqhakamshelwano iingcingo yokuvikela ngokulula intambo ngaphandle ebangela ukuba umonakalo.

Kukho iindlela ezininzi bokulungisa izinto oogesi, ithandwa kakhulu - entabeni phantsi kwentloko iqhosha lemenyu. Kwakhona wasebenzisa Yokutshayelela ngenkani ngokusebenzisa kwipleyiti uqhagamshelo iqhosha lemenyu. Isiphumo kumfowunelwa enokuthenjwa kakhulu kwaye akukho umonakalo ngoomatshini ukuya ucingo.

Kwezinye iimeko, iitheminali zendibaniso ngocingo babe amacebiso ezizodwa. Bona ifakwe intambo, nto leyo ke iqhotyoshelwe yikhabhinethi yombane okanye nasiphi na esinye isixhobo. bamanqatha enjalo ibizwa sisaqhubeka.

Screw terminal block nenkcazo yayo

Ngokusetyenziswa bamanqatha Screw ukuthetha ngonaphakade. Enyanisweni, kodwa iiclamps kakhulu ethandwa, ukwakhiwa leyo enokuthenjwa elula ngexesha elifanayo. Olu hlobo izixhobo zisetyenziswa kuphela ukuzalisa iintambo zombane, kodwa kule zokuphuma. Kananjalo zisetyenziswa ikliphu ye iiterminal ze battery, uqhagamshelo luminaire amaqela kunye nangaphezulu.

Ke eyimveliso eziphathekayo, iiterminal Screw ezintambo eziqhagamshelayo rhoqo ezenziwe ezinepolypropylene kunye polycarbonate, kodwa ngamanye amaxesha ezenziwe polyamide kunye polyethylene. Kufuneka uqonde ukuba olu hlobo divayisi alungele ukusetyenziswa kunye ababhexeshi aluminium. Oku kungenxa ubu ezizodwa kwangaphambili, ngoko xa ukulungisa unako liyonzakalise. Kodwa nje izinto ozifunayo, zekopolo nezinye iingcingo. Amaxesha amaninzi oyicinezelayo terminal Screw block senziwa. Kulo mzekelo, njengoko uphawulo ngayo ngesilungelelanisi eluhlaza, kwakunye nameva ezizodwa kwexesha olululo wire.

iiterminal uqhagamshelo

ezinjengeetheminali Screw, leyo ke kucingelwa ukuba yenye iindidi ezintathu ukuqhagamshela izixhobo ezintambo. Ngokutsho EMP, kuyacetyiswa ukuba kusetyenziswe ngaphezulu kwaye ezinjengeetheminali Self-nokubotshwa. Bona zisetyenziselwa entengo kunye necandelo kweentambo ayikho ngaphezu kwe-2.5 mm kwindawo yangoku 24 A. Loo ikama ukumelana zingumthwalo ngokomyalelo 5 kW. Ukuba zixhobo ngakumbi amandla-olunzulu nonamandla, kuza kufuneka ukuba usebenzise indlela eyahlukileyo.

Okubangel 'umdla kukuba, i kunokwenzeka terminal uqhagamshelo eziplangeni olu hlobo ukuze ucingo-8, nto leyo eye inani elifanayo kwiindawo zokubeka. Esi sigqibo negalelo yokuba wajika ukukhawulezisa phezulu kakhulu awayezinxibile iintambo.

Kule ndlela echazwe ngasentla, kukho ethile mnye. Zigqalwe isithuba lenyuswa kwibhokisi kuhlangana (nalapho ke kuphela xa kuthelekiswa ne-twist). ukhuseleko contact and inqanaba nokuthembeka kulo mzekelo iphezulu kakhulu, ukuba ingadluli umthwalo avumelekile. Kungenjalo, iibhloko terminal uqhagamshelwano yale hlobo ukuze kuphumelele okanye yingozi.

ezinjengeetheminali zibangelwe lokujongana nokufakelwa

Zokwambathisa yamasango kokuxhuma (PPE), ngembonakalo efana cap zeplastiki. Yakhiwa Polymer non-olunokutsha, loo magumbi umlilo okhawulezileyo ngenxa lobushushu avuke. Uyakwazi ukuthetha yokuba injongo yazo - eziphezu zokukhusela umlilo. Noko ke, PPE kunempembelelo entle ngomgangatho uqhagamshelwano ngokubonelela unxibelelwano ngoomatshini. Ukuze benze oku, kufuneka ukukopela bajije bejonge linegunya iingcingo kwi intambo. Ngenxa yoko, ngumthombo ibekwe phakathi kwezindlu, licudisa ucingo ezingundoqo, oko ukuphucula unxibelelwano. Iqhubekekisa walala paste ekhethekileyo ukuphepha igcwala.

Xa esetyenziselwa ezinjengeetheminali lombane olu hlobo, kuba kunokwenzeka ukuba ukufumana uqhagamshelwano lwe iingcingo ngobubanzi ezahlukeneyo. Unako kwakhona ukwakha unxibelelwano phakathi yobhedu aluminiyamu iingcingo. Ukongeza, emthonjeni inempembelelo asisigxina wire esisigxina, ngoko akukho mfuneko ukuba kuhlolwa, njengoko kunjalo ihlangene iqhosha lemenyu.

Akunakwenzeka ukuba wazi izinto ezibalulekileyo ezininzi PPE ukuba ufumane uqhagamshelwano fast and eyiyo, esele kungenziwa nkqu yi wabaqalayo.

Ngokufutshane iiterminal amandla

Mntu uthi le terminal amandla Ibloko isakhiwo ezinokuntsonkotha enkulu ngaphezu embodiments ezichazwe apha ngasentla. Oku kungenxa yokuba i sixhobo enxulumanisa ivumela enkulu cross-candelo kunye iingcingo kwamandla (ngokuqhelekileyo iba ucingo ukusuka 35 ukuya 300 mm isikwere). kokuba zifakwe kwi epleyitini ezifuna eyodwa okanye din-kaloliwe, ngoko ngokufuthi kuthengiswa kwiinguqulelo ezininzi. Iinkcukacha plate sobhedu, isale a ingxubevange etotini. Ngocingo uye washer etsobhileyo ukuba ngokupheleleyo kuthintela buthathaka yomfowunelwa. Ngamanye amaxesha iiterminal amandla likuvumela ukuba ukucwangcisa eziliqela Jumpers zongezelelweyo ezinjengeetheminali ezikufutshane, kananjalo kube lula kakhulu.

Isithintelo jikelele ezinjengeetheminali

A isici esasenza iiterminal umqobo kukuba na kuyilo zabo ezincinane njengemicwana yentsimbi. Lwakutsha nje yahlukana umaleko ubushushu. Le elungileyo terminal distribution block, kuba ngokupheleleyo olungasiwe ngokunxibelelana ngcingo angabamelwane. kwizinga eliphezulu kubangela into enye kwaye udonga ngamnye isikali ngezikhonkwane. Bona Kwakufuneka entabeni ngokuthembekileyo nabo.

Le Iibhokisi Ulwabiwo zifakwa iibhloko terminal kanye isithintelo, njengoko lula kakhulu kwaye athembekile. bamanqatha jikelele yesiphelo ibhloko kunye ityhubhu otyhidiweyo, nganye mayixhotyiswe iperi ngezikhonkwane ukuze nokulungisa macingo. Oku ziluncedo kakhulu xa ufuna ukwenza kweentambo eyayizalwa.

isiphelo

Ke kaloku, ukuba uyakwazi oko kwiitheminali loqhakamshelwano kwala macingo yintoni iintlobo na. Kuyabonakala ukuba izixhobo ezifana kuvumela ukwenza udibaniso, hayi nje ixesha elide, kodwa, okona kubaluleke kakhulu, oluthembekileyo. Okwangoku, ukuthengiswa linani elikhulu ezinjengeetheminali. Ezinye ezifanele neengcingo nge cross-icandelo ezincinane, enye - ukuba enkulu. Kukho ezinjengeetheminali esijijwayo, screwless okanye kwasiso. Sonke sinamandla kunye nobuthathaka bethu. Ngenxa yesi sizathu elula, ukhetho kufuneka kugwetyelwa, ngoko kuphela kwethemba iziphumo ezidibanisayo.
