Inyigisho yo guhitamo umuhanda wa gari ya moshi wa DIN: Amanota agezweho, ibikoresho, n'amahame ngenderwaho yo gushyiraho

TL; DR

Guhitamo icyuma gipima amashanyarazi cya DIN gikwiye ku gice cy’igenzura cy’inganda bisaba guhuza ibipimo bitatu: igipimo cy’ubu kigomba kurenga umutwaro ntarengwa wa circuit ho nibura 20%, ibikoresho byo mu nzu bigomba kwihanganira ibidukikije, kandi imiterere yo gushyiraho igomba kubahiriza amahame ya EN 60715. Iyi mfashanyigisho inyura muri buri gisobanuro hamwe n'amakuru ashobora gupimwa hamwe n'inyandiko zikoreshwa mu buryo bufatika.

Mu myaka irenga icumi ishize dukora ibyuma bya terminal bya OEMs muri Amerika ya Ruguru, i Burayi, na Aziya y'Amajyepfo y'Uburasirazuba, twabonye amakosa amwe yo guhitamo agaruka - ibyuma binini cyane ku bimenyetso by'amashanyarazi make, inzira ntoya zo mu muhanda ku bikoresho biremereye byo mu rwego rwa multilevel, hamwe n'ibidahuye n'ibikoresho bituma habaho gutsindwa kw'ibikoresho. Iyi gahunda igamije gukuraho ayo makosa.

Ni izihe ngero zitangwa ubu ku bibuga bya DIN Rail Terminal Blocks?

Ingano y'amashanyarazi ya DIN terminal block iri hagati ya 24A kuri 2.5mm2 feed-through blocks zisanzwe kugeza kuri 232A kuri 95mm2 power blocks zikomeye, nk'uko bigenwa n'amabwiriza ya IEC 60947-7-1 na UL 1059.

Buri gice cy’ifatizo gifite amanota abiri y’amashanyarazi: ingano y’amashanyarazi akoreshwa (Ie) hakurikijwe IEC 60947-7-1 n’ingano y’amashanyarazi ya UL. Akenshi - ariko si ko buri gihe - asa. Umuvuduko nyawo icyuma gishobora gutwara biterwa n’igice cy’umuyoboro w’amashanyarazi, ubushyuhe bw’ikirere, ndetse niba icyuma gishyizwe mu buryo bumwe cyangwa bushyizwe mu buryo buhuriweho.

Isuzuma risanzwe ry'ubushyuhe hakurikijwe igice cy'insinga

Ibintu Biteye Isoni Udashobora Kwirengagiza

Buri gice cy'inyuma kigomba gukurwaho igihe gishyizwe mu buryo bufite ubucucike bwinshi cyangwa ku bushyuhe buri hejuru ya 40C. Ushingiye ku mategeko rusange ya IEC 60947-1, gukuba umuvuduko w'amashanyarazi ugenwe na:

• Ubushyuhe buri kuri dogere selisiyusi 60: igabanuka kugeza kuri 80% by'umuvuduko w'amashanyarazi
• Ubushyuhe buri kuri dogere selisiyusi 80: igabanuka kugeza kuri 65% by'umuvuduko w'amashanyarazi
• Ibice byinshi by'amabara atandukanye (ibice 3+): kugabanuka kugera kuri 85% kuri buri rwego
• Agace gafunze gafite umwuka muke: gabanya kugeza kuri 80% nibura

Ni ibihe bikoresho byo mu nzu ukwiye guhitamo?

PA66 (Nylon 66) ifite amanota ya V-0 yo gutwika ni yo mahitamo asanzwe ku mazu ya DIN terminal block, akora kuva kuri -40C kugeza kuri +120C, mu gihe polycarbonate (PC) ikundwa cyane ku bikoresho bibonerana bisaba imbaraga nyinshi zo gukurikirana.

Ni izihe ngingo ngenderwaho zo gushyiraho umuhanda wa DIN Rail?

Ibice bya DIN terminal terminal bishyirwa kuri TS35 (ubugari bwa mm 35, ubujyakuzimu bwa mm 7.5 cyangwa 15) cyangwa TS32 (ubugari bwa mm 32) nk'uko bisobanurwa na EN 60715 na DIN EN 50022, aho TS35 ari yo ihame ry’inganda ku bipimo birenga 90% by’ibipimo by’inganda.

Uburyo DIN Rail Terminal Blocks ikora

Ibyuma byinshi bigezweho bya DIN byo ku muhanda wa gari ya moshi bikoresha uburyo bwo gufunga butagira ibikoresho: blok ifata umunwa wo hejuru w'umuhanda wa gari ya moshi mbere, hanyuma ikazenguruka kugeza igihe ikirenge cyuzuyemo impera kigeze ku munwa wo hasi.

1. Kuringaniza icyuma gifunga icyuma ku nguni ya dogere 15-20, ufata agace ko hejuru ku nkombe yo hejuru ya rail ya TS35.
2. Zunguruza bloki imanuka kugeza aho igice cyo hasi cy'impeshyi gihurira n'inkombe yo hasi y'umuhanda.
3. Kanda cyane — ugomba kumva urusaku rwumvikana mu gihe imashini ikoresha imbaraga ifata umwanya wayo inyuma y'umuhanda.
4. Emeza gukorana ugerageza kuzamura agace kari hejuru udakanda ahanditse ngo "release".

Icyemezo cya UL vs CE: Ibyo Injeniyeri Agomba Kwemeza

Ku mishinga yo muri Amerika y'Amajyaruguru, icyemezo cya UL 1059 ni itegeko gikubiyemo ibyuma bipima ubushyuhe kugeza kuri 600V; ku mishinga y'Umuryango w'Ubumwe bw'u Burayi, ikimenyetso cya CE giteganywa na IEC 60947-7-1 ni cyo gisabwa n'amategeko, kandi imishinga myinshi isaba icyemezo cya TUV cyangwa VDE.

Uburyo bwo kwemeza ibyemezo mbere yo gutumiza

1. Icyemezo cya UL: Genzura nomero ya dosiye ya UL iri kuri Ububiko bw'ibicuruzwa bya UL.
2. Itangazo ry’Iyubahirizwa ry’Amategeko rya CE: Ugomba gukoresha IEC 60947-7-1. Genzura kuri Urubuga rwemewe rwa IEC.
3. Icyemezo cya TUV cyangwa VDE: Igenzura kuri TÜV Rheinland cyangwa VDE ububiko bw'amakuru.
4. Itangazo rya RoHS na REACH: Birakenewe kugira ngo umuntu yinjire ku isoko ry'Ubumwe bw'u Burayi.

Uburyo bwo guhitamo ubwoko bwiza bwa Terminal Block

Ubwoko burindwi bw'ingenzi bwa DIN rail terminal blocks — feed-through, ground, fuse, disconnect, multi-level, sensor, na power distribution — buri bumwe bufite imikorere yihariye yo gufunga insinga.

Ubwoko bwa screw vs Spring-Clamp: Kugereranya ikoranabuhanga ryo guhuza

Ibice bya terminal byo mu bwoko bwa screw bitanga imbaraga zo gufunga (3-5 Nm) zo gukoresha ingufu nyinshi zirenze 100A, mu gihe ibice bya clamp bitanga insinga zihuse (igihe cyo kuyishyiraho kigabanukaho hafi 40%) kandi bigakoresha insinga zo mu kabati ko kugenzura kuva kuri 24A kugeza kuri 65A.

Ubwoko bwa screw vs Spring-Clamp vs IDC: Kugereranya ibice bitanu

Ugereranyije n'ibipimo bitanu bishobora gupimwa, spring-clamp itanga uburinganire bwiza kuri 90% by'ikoreshwa ry'inganda mu kugenzura, mu gihe screw-type yiganjemo high-power naho IDC iganjemo high-production pre-wared systems.

Ni iyihe wagakwiye guhitamo?

Hitamo ubwoko bwa Screw igihe: Umuvuduko w'uruziga urenga 65A, insinga zirenga 16mm2, ahantu hatembera cyane, cyangwa abakozi bashinzwe serivisi bahuguwe n'ibikoresho bya torque.

Hitamo Spring-Clamp igihe: ikoreshwa ni 65A cyangwa munsi yayo (ikubiyemo >85% by'inganda zikora insinga), umuvuduko w'insinga ni wo w'ingenzi, cyangwa impinduka nyinshi z'insinga ziteganijwe.
