Welding na jan karfe waya: a review na hanyoyi da kayan aiki. Soldering ko waldi na jan wayoyi - wanda shi ne mafi alhẽri?

Babban aiki a lokacin da ka gama kowace lantarki lamba ne don tabbatar da su m juriya. Lokacin da matalauta lamba juriya tsakanin jan wayoyi da aka muhimmanci inganta, sakamakon wani dumama na USB. Akwai hanyoyi da yawa a tuntube sadarwa, amma mafi abin dogara da kuma tasiri ne dauke da za a welded jan waya. Wannan fasaha damar monolithically gama duk waya igiyoyin, game da shi, da cimma mafi ƙasƙanci yiwu lantarki juriya. A sakamakon dumama wayoyi da aka shafe, haka muhimmanci ƙãra matakin na wuta aminci.

Hanyoyin da connection wayoyi

Copper ne babban shugaba abu. By darajojin physico-sinadaran Properties na wannan abu (high ductility, rashin elasticity), aiki tare da su yana da halaye. Banana na'ura dokoki ce cewa ayyukan a kan wani connection reshe, kuma okontsovyvaniyu jijiyoyinmu daga igiyoyi da wayoyi iya yi da soldering, waldi, crimping ko squeezing (aron kusa, dunƙule, da dai sauransu). Kowace daga cikinsu yana da halaye, wanda za a tattauna a kasa.

Fili wayoyi da stranding

A sauki karkatarwa da wayoyi da aka haramta PUE, kamar yadda shi ne mafi kasa aiki, short-rayu da wuta connection. Duk da wannan, da m sana'a da ba su gushe ba don amfani da wannan hanyar, ko da yake sakamakon wannan "craft" na iya zama sosai plavchevnymi.

Yanã mai karkatar wayoyi yana daya babbar drawback: jan sadarwa ƙarshe maras kyau da kuma raunana, ƙarshe gaba daya hallaka saboda da high mika mulki juriya.

Ya kamata a tuna da cewa karkatacciyar hanya za a iya amfani da kawai a na kwarai lokuta, idan an gaggawa bukatar mayar da wutar lantarki da sauran hanyoyi a wani musamman halin da ake ciki ne ba samuwa. Yana da muhimmanci sosai ga kula game da ingancin, aminci kuma aminci daga cikin connection.

An tsananin haramta:

• Danganta wayoyi kafa daga daban-daban kayan (aluminum da kuma jan).
• Haxe m jan karfe waya tare da wani multifilamentary.

Stranding tsari ne kamar haka:

1. Clear waya rufi daga nesa na 6-8 cm daga gefen.
2. Aiwatar daya waya zuwa wasu kuma crosswise maximally m amarya. Idan giciye sashe na jan karfe waya fiye da 1 sq. mm, da aiki da aka yi tare da filaya.
3. Ciza da tukwici na forceps sauran wayoyi.
4. Karkatacciyar makaran ta amfani da musamman insulating kayan (PVC, ko zafi ji ƙyama shambura, iyakoki) ko dama yadudduka na insulating tef. Rufi dole ne dole kama insulating Layer wayoyi.

matsa lamba gwajin

A tsari ne mai aiwatar da a haɗa wayoyi ta hanyar da musamman crimping a tubular hannun riga ko tip. Wadannan na'urori ana amfani da, idan giciye sashe na jan karfe waya ne 2,5-240 sq. mm. Indisputable abũbuwan amfãni daga crimp fasahar ne gudun da kuma daidaito na aiki, kazalika da m karko da aminci sadarwa.

Domin crimping amfani da musamman kayan aiki - inji, na'ura mai aiki da karfin ruwa ko lantarki filaya ko sana'a obzhimochnye latsa. Selection na casings za a dogara ne a kan yawan sassan da alaka da wayoyi.

Bayan yanã fizge tufarsu da kuma tsabtace daga mai rai, su ne aiyuka ma'adini-vaseline manna, sa hannun riga da kuma samar da wani crimp. Matsawa hannayen riga saniyar ware.

crimping tashoshi

Aikace-aikace daban-daban crimps tashoshi da aka yadu aikata ta haɗa lantarki kantuna, sauya, haske maras motsi, kazalika da shigarwa na switchboards. Wadannan na'urori ba da damar m da sauri Haša jan m waya, stranded waya amma ba tare da pre-welds ko crimp tube tip cikin dunƙule matsa m ne ba zai yiwu ba.

A indisputable abũbuwan amfãni daga cikin dunƙule tashoshi iya hada connectivity aluminum wayoyi da tagulla, da kuma ma babu bukatar m kadaici da lambobi.

Duk da haka, irin wannan connection ne ba tare da flaws. Ya na bukatar lokaci-lokaci tabbatarwa, wanda ya kunshi a dõmin karkatarwa da clamping abubuwa. Copper - wani mai taushi abu, yiwuwa ga "yayyo" daga karkashin load. Idan har yin haši ta hanyar spring-ɗora Kwatancen rigidly cleat tashoshi, saboda wani ma kananan yanki lamba saman a nauyi kaya ne mai tsanani da kuma sakin spring abubuwa, inda su elasticity rage-rage tare da fili quality.

Pike VS-waldi

Don tabbatar da kyau lamba da aka fi amfani da soldering ko waldi na jan wayoyi. Cewa mafi kyau daga cikin wadannan hanyoyi? Shakka, waldi. Gaskiyar cewa soldering - tsari ne quite laborious da lengthy, musamman idan kana son haɗawa stranded jan na USB. Plus, da commissural mahadi ƙarshe halaka saboda gaban na uku, mafi friable da kuma sauƙi fusible karfe - solder. A gaban miƙa mulki juriya a cikin gidajen abinci na daban-daban gami taimaka wa bayyanar hallakaswa sinadaran halayen da wasu mummunan matakai.

Lokacin da waldi aka yi da jan karfe waya, da kalmar "lamba" kullum vuya saboda monolithic fili an samu daga cikin wannan irin karfe. Babu shakka, wadannan mahadi bambanta rikodin low juriya, inda zafin yana da wuya a sake.

Nan da nan ya kamata a lura da cewa wannan aikin na bukatar wani adadin na ilimi da kuma kwarewa. Paradoxically, amma ingancin ne mafi alhẽri dõmin karkatarwa matalauta soldering, tuna da wannan.

Soldering aiwatar fara da wani pre-jiyya na da iyakar da wayoyi rufi da kuma oxides. Sa'an nan kuma suna birgima, mai rufi da musamman abu - juyi sa'an nan hocus. Solder da wayoyi iya ba kawai jan karfe, amma kuma aluminum, babban abu - a zabi da hakkin juyi da kuma solder. Amfani da aiki acid juyi ba da shawarar, kamar yadda ake bukata ya zama a kan wayoyi, irin wannan cewa fili za a narkar da sauri.

Daya soldering daukan lokaci mai tsawo, amma idan yi daidai, a dangane zai zama abin dogara da kuma m. Da zarar da wayoyi sun sanyaya, su dole ne a hankali makaran.

waldi

A mafi high quality, kuma kafaffen haɗi Forms waldi jan waya. Da juriya a lamba waya ba ya wuce misali awo na da juriya. Wannan hanya ba ya bukatar lokaci mai yawa, kuma an dauke su gwada da sauki. A gaban da m basira da ilmi na waldi na jan wayoyi a gida ne doable.

Lokacin dauke da fitar waldi aikin dukan dokokin da wuta da kuma lantarki aminci dole a lura tsananin. Don kauce wa konewa da ido raunin kamata ko da yaushe amfani sirri m kayan aiki - m tufafi da kuma safar hannu, waldi kwalkwali, ko fitattun idanu.

Welding kayan aiki

Fili wayoyi da waldi yi apparatuses daban-daban. Shi ne mafi dace don amfani mai inverter inji for waldi jan wayoyi, tun da irin wannan na'urorin da ake halin kananan size da kuma nauyi, tattali ikon amfani da mai fadi da kewayon waldi halin yanzu saituna. Wadannan abũbuwan amfãni ne ikon samar da ci gaba da kona lantarki baka.

Idan ka shirya wani gagarumin adadin lantarki aiki, da saye da waldi na'ura inverter ne gaba ɗaya dace da wajaba a kansa. Bugu da kari, wannan kayan aiki, lalle zã ba karya "matattu nauyi" a nan gaba.

Features na aiwatar da waldi wayoyi daga jan

Waldi jan waya na iya zama duka AC da kuma DC ƙarfin lantarki a rates na 15-30 C. Yana da kyau idan na'urar samar da damar daidaita yanzu.

Alal misali, don Weld biyu jan conductors na 1.5 sq. mm, isa 70 A. Domin waldi na uku wayoyi da wannan giciye sashe wajibi ne a kara na yanzu zuwa 90 A. fili uku conductors na 2.5kb. mm zai bukaci daga 80 zuwa 100 A, a waldi waya biyar kama - 120 A. Idan zaba ganiya waldi halin yanzu ba ya faruwa "mai danko" na lantarki da kuma baka ne isasshe barga.
Domin waldi na jan wayoyi amfani da carbon-jan "pencils" (wayoyin). Idan ba haka ba, shi ne zai yiwu a yi amfani da carbon sandunansu daga fensir batura.

waldi ayyuka

A tips na wayoyi tsawon 5-6 cm da aka tsarkake ta da wani insulating shafi da kuma suna juya fara daga sassan na rufi, da barin wani 5-6 mm a karshen wata karkatarwa untwisted form. Wadannan tips dole ne za a yada, folded a layi daya da kuma kusa da juna. By dõmin karkatarwa uku ko fiye da wayoyi, a karshen ka har yanzu bukatar barin kawai biyu free tip, da kuma sauran yanke a batu na karshe zagaye na faduwa. Idan inji shi ne ba iko isa, wannan karkatarwa zai ba da damar mafi saukin samar da wata narke dutsen ado. Idan akwai isasshen halin yanzu a cikin waldi na'ura iya yin wani sauki karkatarwa.

Bugu da ari karkatacciyar clamped via clamping waldi. Idan wannan na'urar ne ba ya nan, za ka iya amfani da bayyana tsohon filaya.

The shirya fili aka welded carbon lantarki. A lokacin waldi, da tagulla wayoyi suna narke bar untwisted iyakar kafin kafa na zubi ball. Don tabbatar da wani abin dogara inji da lantarki lamba waya, da narkewa zone kamata tabbata a samu zuwa stranding.

Duration waldi kada wuce 2-3 seconds, in ba haka ba waya rufi Weld. Bayan cikakken sanyaya na fili fitar da kadaici yin amfani da mahara yadudduka na tef ko musamman hula, PVC, ko zafi ji ƙyama tubing.
