Kunanirwa kwa Terminal Block kubera ubushuhe bwinshi: Ingamba zo kwirinda gushyiraho ikirere gishyuha

TL;DR — Niba ufite amasegonda 60 gusa

• Ishyirwaho ry'amashanyarazi yo ku nkombe z'ubushyuhe rigira igipimo cyo kwangirika kwa 15-25% by'ibikoresho bya terminal block mu mezi 18 ugereranije na 2% mu bihe by'ubushyuhe - kuko ubushuhe bugera kuri 80%+ bw'ubushuhe bwiyongera byihutisha ingese ya galvanic aho insinga zihurira n'imashini, bikongera ubushobozi bwo guhangana n'imashini kugeza igihe ubushyuhe butera ikibazo cyo guhagarara k'uruziga. Ibikoresho bya terminal bya IP67 bifite inkweto za silicone zo gufunga ni ngombwa ku bikoresho byo hanze by'ubushyuhe.
• Imiterere y'aho ibyuma bipfundikiye bikorera imiyoboro y'ubushuhe mu miyoboro y'amazi aho insinga zinjira - ndagaragaza aho ibyuma bipfundikira bipfundikiye bifite aho bipfundikira bipfundikiye kugira ngo bikoreshwe hanze y'ubushyuhe aho kwinjira k'ubushuhe ari cyo kintu cy'ingenzi gituma amazi ananirwa.
• Kwinjira mu nsinga zifunze hakoreshejwe inkweto za silicone zo gufunga cyangwa umuyoboro w’ubushyuhe ugabanya ubushyuhe aho insinga zinjira bikuraho inzira y’ibanze y’ubushuhe butera ingese yo guhuza insinga n’insinga.

Ibyo namenye ku bijyanye n'ibura ry'amashanyarazi mu turere dushyuha nyuma y'imyaka makumyabiri yo gutanga amashanyarazi mu bice bya Terminal Block

Ubwo natangiraga gutanga ibikoresho byo guhuza amashanyarazi ku ba rwiyemezamirimo b'amashanyarazi bo muri Aziya y'Amajyepfo y'Uburasirazuba mu 2006, ikirego cyakunze kugaragara cyane ni ukubera ko ibyuma byangiritse mu nyubako z'inkombe z'ubushyuhe. Ba rwiyemezamirimo b'amashanyarazi barangizaga gushyiraho bundi bushya, sisitemu ikora neza mu mezi make ya mbere, hanyuma ibyuma byihariye bigatangira kwangirika - mu ntangiriro rimwe na rimwe, hanyuma buhoro buhoro kugeza igihe ibyuma byangiritse burundu. Kubera ko ibyangiritse byakwirakwijwe mu nyubako nyinshi mu nyubako imwe aho kuba ahantu hamwe, imiterere yerekanye ikibazo cy'ibidukikije aho kuba ikibazo cy'imikorere yo gushyiraho. Igihe nasuzumaga ibyuma byangiritse byagarutse mu nyubako z'inkombe z'ubushyuhe, uburyo bwangiritse bwari buzwi: ingese ya galvanic ku buryo insinga zihuza n'aho zihurira, iterwa n'ubushuhe bwinjira mu nzu y'ibikoresho bya terminal.

Kubera ko ibidukikije byo ku nkombe z'ubushyuhe bifite ubushyuhe buri hagati yabyo busanzwe burenga 80%, kandi kubera ko ubushyuhe bwa buri munsi mu turere dushyuha two ku nkombe butuma amazi ahinduka ku butaka bukonje mu masaha ya mugitondo mbere y'uko izuba rishyuha ikirere, amashanyarazi n'ibirimo - harimo n'ibice by'amashanyarazi - bihura n'ibihe by'ubushuhe bya buri munsi. Kubera ko ububiko bw'ibice by'amashanyarazi - nubwo byaba bifite urugero runaka rwo kurinda ubushuhe - butuma amazi make y'ubushuhe yinjira uko igihe kigenda gihita binyuze mu gukwirakwira no guhumeka bitewe n'ubushyuhe, ubushuhe bwinshi buri mu bubiko bw'ibice by'amashanyarazi butuma habaho ingese ya galvanic aho amashanyarazi ahurira.

Kubera ko ubu nashyigikiye uburyo bwo gushyiraho amashanyarazi mu mishinga irenga 60 yo gushyiraho amashanyarazi mu bihe bishyuha hirya no hino mu majyepfo y'uburasirazuba bwa Aziya, mu Burasirazuba bwo Hagati, no muri Amerika y'Epfo, uburyo bwo gukora amashanyarazi mu bice bishyuha bitewe n'ubushuhe ni bwo bukunze kugaragara cyane - kandi ni bwo buryo bukunze kugaragara cyane. Kubera ko uburyo bukwiye bwo gushyiraho amashanyarazi (ibikoresho bya IP67 bifunze neza hamwe n'insinga zifunze neza) hamwe n'uburyo bwo gushyiraho amashanyarazi (kwinjira mu nsinga zifunze neza, gusohora amazi mu buryo bukwiye) hamwe bikuraho uburyo bwo kwinjira mu mazi, ikibazo cyo gushyiraho amashanyarazi mu bice bishyuha kirakemuka - ariko gusa iyo uburyo bukwiye bwo gushyiraho amashanyarazi n'uburyo bwo gushyiraho amashanyarazi bikemura ikibazo cy'ishingiro aho kuvura gusa ibimenyetso binyuze mu gusimbuza ibikoresho byangiritse hamwe n'ibikoresho bisa bitafunze neza.

Ubuhanga bwa elegitoroniki mu kwangirika kw'ibice by'amashanyarazi bikomoka ku bushyuhe

Ingeso ya galvanic itera impanuka za terminal block mu duce dushyuha iterwa n'imikoranire ya electrochemical hagati y'ibyuma bitandukanye mu gihe hari electrolyte - muri iki gihe, agace gato k'amazi gafatana ku buso bw'imbere bw'aho terminal block ikorera. Kubera ko aho terminal block ihurira hagizwe n'icyuma cy'umuringa cyangwa umuringa hamwe n'isoko y'icyuma cyangwa screw mechanism, ibyuma bibiri bitandukanye mu gihe hari ubushuhe birema galvanic corrosion cell ituma icyuma gikunze gukora cyane (ubusanzwe icyuma gitwikiriwe na zinc) cyangirika cyane mu buryo bugaragara aho connection ihurira.

Igicuruzwa cyangiritse gikorerwa aho insinga ihurira n’insinga akenshi ni zinc oxyde cyangwa zinc hydroxide ku byuma bifatanye na zinc, na copper oxyde cyangwa copper chloride ku nsinga z’umuringa. Kubera ko ibi bikoresho byangiritse ari amashanyarazi mabi kandi ntibitwara umuriro, kwirundanya kwabyo ku nsinga z’amashanyarazi byongera buhoro buhoro ubudahangarwa bwo gukorana. Kubera ko ubudahangarwa bwo gukorana bwiyongera butanga ubushyuhe hakurikijwe isano ya Power = Current² × Resistance, ubushyuhe aho buhurira bwihutisha umuvuduko wa ruswa mu gihe icyarimwe bwangiza icyuma gifata insinga n’icyuma gifata impera cyangwa screw.

Igipimo cy’ingenzi cyo kudahuza n’ubushyuhe - aho ubushyuhe buturuka aho buhurira burenze ubushobozi bwo gukwirakwiza ubushyuhe bw’igice cy’amashanyarazi - ubusanzwe kiri hagati ya mililiyoni 100-500 ku rugero rusanzwe mu bwubatsi bw’amashanyarazi (ampere 10-32). Kubera ko napimye ubushobozi bwo kudahuza n’ubushyuhe bwa mililiyoni 50-200 mu bice by’amashanyarazi bimaze amezi 12-18 mu turere dushyuha, kwiyongera gukomeye k’ubudahuza n’ubushyuhe bivuze ko ibice by’amashanyarazi muri ibi bice bihora byegera igipimo cy’ubushyuhe - kandi ikindi kintu icyo ari cyo cyose cyongera umuvuduko w’umuzigo cyangwa kikagabanya gato gukwirakwiza ubushyuhe (nk’ubushyuhe bw’ikirere bwiyongera mu gihe cy’ubushyuhe) gishobora gutera ikibazo cyo kunanirwa k’ubushyuhe.

Ibipimo by'isuzuma ry'uburinzi bw'ingress (IP) ku bibuga by'ikirere bya Tropical Terminal Blocks

Sisitemu yo gupima Ingress Protection (IP), yasobanuwe muri IEC 60529, igaragaza urwego rw'uburinzi butangwa n'amashanyarazi mu kwirinda kwinjira kw'ibintu bikomeye n'ubushuhe. Kubera ko amanota ya IP agena uburyo terminal block idashobora kwihanganira kwinjira kw'ubushuhe mu bihe runaka by'igeragezwa, guhitamo amanota ya IP akwiye mu bidukikije byo mu turere dushyuha bisaba guhuza amanota n'imiterere yihariye yo gushyiraho aho gukoresha uburyo rusange bwo gupima ikirere.

Ku bijyanye n'amashanyarazi yo hanze aho ibyuma bishyirwa mu buryo bw'ikirere bihura n'imvura, ubushuhe buturuka ku muyaga, no kwibira mu mazi by'agateganyo (nk'uko bigenda mu miyoboro y'amazi yuzuye mu gihe cy'imvura nyinshi), ndavuga ibyuma bishyirwa mu buryo bw'ikirere bifite igipimo cya IP67 nibura. Kubera ko IP67 igaragaza uburyo bwo kwirinda ivumbi ryinjira (ridafata ivumbi) no kwirinda ingaruka zo kwibira mu mazi by'agateganyo (kugeza kuri metero 1 y'amazi mu minota 30), iki gipimo gikubiyemo uburyo bukabije bwo guhumeka mu mazi yo hanze. Kubera ko ibyuma bishyirwa mu buryo bw'ikirere bifite igipimo cya IP67 bikoresha ibyuma bifunga bya silicone n'imiterere y'amazu afunze kugira ngo bigere ku gipimo, bihenda inshuro 2-3 ugereranyije n'ibikoresho bisanzwe bya IP20 - ariko ikiguzi cy'igiciro gifite ishingiro ryo gukuraho kwangirika kw'ubushuhe buterwa n'ubushuhe.

Ku bikoresho by'amashanyarazi byo mu turere dushyuha bitwikiriwe ariko bitarapfundikiwe — nk'ibice byo hanze bitanga igicucu n'uburinzi bw'imvura ariko ntibifunze ku bushuhe buturuka ku muyaga cyangwa ku bushuhe — ndagena amanota ya IP65 ntarengwa. Kubera ko IP65 igaragaza uburinzi butinjira mu mukungugu no kurinda amazi aturuka mu cyerekezo icyo ari cyo cyose, itwikira ubushuhe buturuka ku mvura ituruka ku muyaga n'ubushuhe buturuka mu bikoresho bitwikiriwe ariko bitarapfundikiwe. Kubera ko amanota ya IP65 ashoboka iyo habayeho igishushanyo mbonera gihendutse kurusha IP67, ibisobanuro bya IP65 birahendutse cyane ku bikoresho aho kwibira by'agateganyo atari ikintu gifatika.

Igishushanyo mbonera cya "Spring Clamp" vs "Screw Clamp" ku bidukikije byo mu turere dushyuha

Igishushanyo mbonera cy'urukuta rw'impeshyi - gikoresha uburyo bwo gufunga insinga kugira ngo gikomeze gukurura umuvuduko ku nsinga zishyirwamo - cyabaye igishushanyo mbonera cy'urukuta rw'impeshyi mu bikoresho by'amashanyarazi bigezweho kubera umuvuduko wacyo wo guhuza (nta gukosora screwdriver bisaba) no kugumana insinga zidakomeza kubungabungwa. Ariko, ku bikoresho byo hanze byo mu turere dushyuha aho amazi yinjira ari bwo buryo bw'ibanze bwo kwangirika, igishushanyo mbonera cy'urukuta rw'impeshyi gifite intege nke z'ibanze: uburyo bwo gufunga insinga butuma amazi yinjira mu gice cy'impeshyi binyuze mu gukora kwa capillary ku murongo w'insinga.

Umuyoboro w'ubushuhe mu miyoboro y'impeshyi ubaho kubera ko insinga zishyirwa mu gice cy'impeshyi zidafunze neza aho zisohokera mu gisenge. Kubera ko uburyo bw'impeshyi busaba icyuho kugira ngo insinga zishyirwemo kandi zigumeho, kandi kubera ko imbaraga z'impeshyi zikomeza gukorana n'icyuho cy'impeshyi, ubushuhe bugera ku buso bw'insinga zo hanze bushobora gukururwa mu gisenge cy'impeshyi binyuze mu gikorwa cy'imiyoboro y'impeshyi ku murongo uri hagati y'uburyo bw'impeshyi n'uburyo bw'impeshyi. Kubera ko iyi nzira y'ubushuhe ijyanye n'imiterere y'impeshyi kandi ntishobora gukurwaho burundu hatabayeho kwangiza imikorere y'impeshyi, sinsaba ko imiyoboro y'impeshyi ikoreshwa mu gushyiramo ibyuma byo hanze mu turere dushyuha aho ubushuhe bwinjira ari cyo kibazo cy'ingenzi mu bidukikije.

Igishushanyo mbonera cy'aho insinga zishyirwa - gikoresha vis kugira ngo gishyireho umuvuduko wo gufunga ku muyoboro w'insinga - gitanga imiterere myiza yo kuziba ubushuhe aho insinga zinjira iyo zikomejwe neza. Kubera ko insinga zishyirwa ku muyoboro w'insinga (nyuma yo gukuraho insulation), kandi kubera ko isano iri hagati y'insinga n'umutwe w'insinga ituma habaho umuyoboro udafata umwuka iyo zikomejwe neza, isano iri hagati y'insinga n'umutwe w'insinga ntirema umuyoboro wa capillary aho insinga zinjira. Kubera ko insinga zishyirwa ku muyoboro w'insinga kandi zemeza neza ubujyakuzimu bw'insinga n'ubwiza bw'umuyoboro, itanga icyizere cy'ubwiza bw'inyongera ku buryo ingirakamaro mu turere dushyuha aho uburyo bwo kuzibungabunga bugoye.

Ibisobanuro byo Gufunga Insinga ku Gushyiramo Ibikoresho byo Gushyiramo Ibikoresho byo Hanze bya Terminal Tropical

Uburyo bwo gufunga insinga ni bwo buryo bw'ingenzi bwo gushyiraho bugena niba icyuma gipima IP kigera ku burinzi bw'ubushuhe mu turere dushyuha two hanze. Kubera ko insinga yinjira muri icyuma gipima uburebure itanga inzira yo kwinjiramo ubushuhe mu gihe icyuma gifunga kidakora neza - cyane cyane mu kuva ku ikoti ry'insinga ryo hanze (risanzwe ridafite ubushuhe kandi ridashobora kuvogerwa) kugera ku gikoresho cyakuwemo imbere muri icyuma - aho insinga yinjira hagomba gufungwa hakoreshejwe uburyo bukuraho inzira y'ubushuhe muri iri hinduka.

Uburyo bwo gufunga inkweto za silicone ni bwo buryo bwizewe bwo gufunga insinga mu gushyiraho ibyuma byo hanze bya terminal. Kubera ko inkweto za silicone zitanga uburyo bworoshye bwo gupfuka ibyuma, zifunze neza kandi zifunga neza hagati y’ikoti ry’insinga n’aho terminal block ikorera, zuzuza icyuho cyose aho binjirira kandi zigakomeza gukora neza mu gihe cy’ubushyuhe n’izuba mu bihe byo hanze bya terminal. Kubera ko silicone ikomeza koroha no gufatana mu bushyuhe buri hagati ya -60C na +200C, ntabwo ikomera cyangwa ngo ivunike mu gihe cy’ubushyuhe bubera mu duce dushyuha twa terminal.

Uburyo bwo gufunga imiyoboro yo gushyushya hakoreshejwe uburyo bwo gufunga imbere butanga ubundi buryo bwo gufunga bukwiriye cyane cyane ibice bya nyuma bifite insinga zizengurutse. Kubera ko imiyoboro yo gufunga igenda igabanuka cyane hafi y'insinga kandi agace k'insinga kagasohoka kugira ngo kuzuza icyuho cyose kiri ku murongo w'aho insinga zikorera, bituma habaho ihindagurika ry'ubushuhe rihamye kandi ririnda ubushyuhe mu buryo bw'amashanyarazi. Kubera ko uburyo bwo gufunga ubushyuhe busaba isoko y'ubushyuhe (imbunda y'umwuka ushyushye cyangwa itoroshi) mu gihe cyo kuyishyiraho kandi ntibyoroshye kuyigenzura nk'uburyo bwo gufunga silicone, nkunda uburyo bwo gufunga silicone mu bikorwa byo hanze aho kugenzura ubuziranenge bw'iyinjizwa bigorana.
