Gusobanukirwa amanota ya 1000V na 200A: Icyo imibare isobanura mu by'ukuri
Iyo tuvuze ku "igipimo cya 1000V" na "ubushobozi bwa 200A," tuba tuvuga ku bipimo bibiri bitandukanye by'amashanyarazi - kandi kubivanga ni ikosa nabonye injeniyeri zikora kenshi mu myaka 15 maze muri uru rwego.
Igipimo cy'ingufu (Voltage Rate) (1000V): Ikibazo cyo gukingira
Igipimo cya 1000V gishingiye ahanini ku buziranenge bw'uburinzi bw'amashanyarazi, ntabwo ari ubushobozi bw'umuyoboro w'amashanyarazi. Kuri buri IEC 60947-7-1, ibyuma byagenewe uruziga rufite ubushyuhe bwa AC bugera kuri 1000V bigomba kugira intera ntoya ya mm 8 n'intera yo hagati y'inkingi zegeranye ya mm 5.5 - kandi izi ntera zipimirwa ku gice cy'ubworoherane kibi cyane. Kubera ko ibikoresho byo mu nzu (ubusanzwe ni PA66 nylon ifite fibre y'ikirahure ya 30%) bigomba kwihanganira voltage ya impulse idakurikiranwa cyangwa ngo ivunike, dukoresha polyamide ya UL94 V-0 igabanya umuriro ifite igipimo cyo gukurikirana (CTI) kirenga 400V.
Mu murongo wacu w’umusaruro, buri gice cy’amashanyarazi cya 1000V gikorerwa ikizamini cy’imbaraga za dielectric za 2200V AC mu masegonda 60 — ibyo bikaba bikubye kabiri voltage isanzwe, kuko Gukingira bigomba kugumana imbaraga z'amashanyarazi zidasanzwe zikorwa buri munsi n'inganda zitangira gukora moteri, guhinduranya contactor, n'imikorere ya capacitor bank..
Igipimo cy'ubu (200A): Ikibazo cy'imicungire y'ubushyuhe
Igipimo cya 200A nacyo nticyasobanuwe neza. Ni igipimo cy'ubushyuhe, ntabwo ari umupaka ufatika ku rujya n'uruza rwa electron. Ku muyoboro uhoraho wa 200A, igihombo cya I²R muri busbar y'umuringa ya 16mm² gitanga ubushyuhe bwa watts zigera kuri 12-15 kuri metero imwe - kandi mu gice cyo kugenzura gifunze kuri dogere selisiyusi 40, ubwo bushyuhe bugomba kujya ahantu runaka. Niyo mpamvu ubushyuhe bugomba kujya ahantu runaka. Igipimo cy'ubushyuhe bw'igice cya nyuma cy'amashanyarazi gihora gipimirwa ku bushyuhe bwihariye (ubusanzwe ni 40°C kuri IEC 60947-7-1) kandi gifata ko umwuka uzenguruka igice cyacyo urimo umwuka.
Ubumenyi bw'ibikoresho bya Busbar: Impamvu umuringa ari ingenzi kurusha uko ubitekereza
Ndashaka kuvuga nta guca ku ruhande hano: Ibikoresho bya busbar biri mu gice cy’inyuma ni cyo kintu cy’ingenzi cyane kigena imikorere yacyo mu buryo bufatika — kandi ni naho abakora ibikoresho bigabanya ikiguzi bagabanya amafaranga.
Hari ibikoresho bitatu bya busbar bikunze kuboneka ku isoko, kandi bikora mu buryo butandukanye cyane:
| Ibikoresho bya Busbar | Ubushobozi bwo gutwara ibintu (% IACS) | Ubushobozi bwo gutwara ubushyuhe (W/m·K) | Imbaraga zo Gukurura (MPa) | Igipimo cy'Ibiciro |
|---|---|---|---|---|
| Umuringa w'amashanyarazi (C11000) | 99.9% | 391 | 220-250 | 100 |
| Umuringa (C26000) | 28% | 120 | 300-400 | 55 |
| Umuringa ukozwe mu gikombe | 99.5% (ubuso) | 385 | 220-250 | 115 |
Dukoresha gusa umuringa wa C11000 electrolytic kuri terminal blocks zacu zose za 200A-rated busbar. Kuki? Kubera ko Uduce twa bus brunze dukoresha ubushyuhe bwa 200A tuzagera ku bushyuhe buri hejuru ya 25-30°C ugereranyije n’uduce twa bus brunze dukoresha ubushyuhe bungana na bwo - kandi iryo tandukaniro ry’ubushyuhe rituma habaho kugabanuka k’umuvuduko w’amashanyarazi ku miyoboro ya screw, kwiyongera k’umuvuduko w’amazi, no kugabanya igihe cyo kubaho k’umusaruro. Itandukaniro ry'igiciro hagati y'umuringa n'umuringa ku gice gisanzwe cya busbar gifite imyanya 10 ni hafi $0.80-1.20 mu bikoresho fatizo - ntabwo ariho niteguye kureka.
Ikoranabuhanga ryo Guhuza Insinga n'Ikoranabuhanga: Guhuza Ingufu z'amashanyarazi n'Ubushobozi
Intera yo kwakira insinga ya 200A busbar terminal block ikunze kuba hagati ya 6mm² (AWG 10) na 70mm² (AWG 2/0) ku ruhande rw'ingenzi rw'inyongera, aho amashami yakira 1.5mm² kugeza 16mm² (AWG 16 kugeza 6). Uru rugero rwagutse rwo kwakira ntabwo ari impanuka — rugaragaza ukuri kw'amashanyarazi mu gukwirakwiza ingufu: urubuga nyamukuru rutwara 200A yose (niyo mpamvu ari ntarengwa ya 70mm²), mu gihe amashami amwe ashobora gukurura hagati ya 2A na 63A (niyo mpamvu ari hagati ya 1.5 na 16mm²).
Dutanga ikoranabuhanga ritatu ryo guhuza, buri rimwe rifite ibyiza bitandukanye:
Guhuza icyuma gifunga screw (umukozi wacu w'akazi): Iskururu y'icyuma ikandagira icyuma gifata icyuma ku gice cy'umuringa, bigatuma habaho ubushyuhe bukonje budafata gazi ku gice cyo hagati cy'aho gihurira. Iyi ni yo ihuriro ryizewe cyane mu gukoresha ingufu nyinshi kuko vis ikoresha torque ya 2.0-3.5 Nm - ihagije kugira ngo ihindure gato icyuma gikoresha umuringa kandi ikore icyuma gihuza ibyuma kirwanya gucika intege bitewe n’ihindagurika ry’amashanyarazi. Ikibazo ni ikihe? Gushyiramo bifata amasegonda 15-20 kuri buri mugozi.

Ubu ni bwo bwoko bwonyine bwo guhuza bukoresha neza ibyuma biyobora amashanyarazi biri hejuru ya mm² 35, kandi ni byo twavuze kuri 150A na 200A zose z'ingenzi zinjira nk'ibisanzwe.
Impamyabumenyi n'Iyubahirizwa ry'Amabwiriza: Icyo Umugenzuzi Wawe Azagenzura
Niba hari isomo rimwe nize mu buryo bugoye mu myaka ya mbere y'umwuga wacu wo gukora inganda, ni iri: Impamyabushobozi si imitako y'ubushake — ni imbogamizi ntoya ku kwinjira mu isoko ry'inganda rikomeye. Dore ibyo ukeneye kugenzura ku rupapuro urwo arirwo rwose rwa DIN rail busbar terminal block specification:
IEC 60947-7-1 — Iri ni ryo hame mpuzamahanga ry’ibanze ku matsinda y’ibikoresho bya terminal bikoreshwa mu bikoresho byo gusimbuza umuriro muke n’ibikoresho byo kugenzura. Rigena ingufu z’amashanyarazi (≤1000V AC), ingufu z’amashanyarazi, ubushobozi bwo gukoresha mu bice bitandukanye, na — by’ingenzi — Uburyo bwo gupima amashanyarazi y’umuvuduko mugufi (SCCR). Kuri buri ivugurura riheruka rya IEC 60947-7-1, terminal blocks zigomba noneho kugaragaza agaciro kazo ka SCCR mu buryo bweruye, ibyo bikaba bigomba guhuzwa n'ibikoresho birinda byo hejuru.
UL 1059 — Ikigereranyo cya Amerika y'Amajyaruguru, gitwikiriye ibyuma bya terminal bifite ubushyuhe bugera kuri 1500V. Ikizamini cya UL 1059 kirakomeye kurusha IEC mu bintu byinshi by'ingenzi: gisaba ikizamini cyo kwihanganira dielectric kuri voltage ya 2 × + 1000V (ugereranyije na voltage ya IEC ya 2 ×), kandi gitegeka ibizamini by'ubushyuhe ku muvuduko w'amashanyarazi mu mizingo 50 (ugereranyije na IEC ikizamini cyo kuzamuka k'ubushyuhe). Kuri buri UL 1059 Ed. 6-2024, ivugurura riheruka ryongeraho ibisabwa binoze ku makinga y'ingufu zirinda amashanyarazi.
Porogaramu yacu y'impamyabumenyi nk'umukozi uruganda rukora ububiko bw'imodoka za Din Rail Busbar irimo: Ikimenyetso cya CE (EU) (kubahiriza amategeko), urutonde rwa UL (dosiye iraboneka igihe uyisabye), imicungire y'ubuziranenge ya ISO 9001:2008, isuzuma rya SGS ry'umuntu wa gatatu, kubahiriza amategeko ya RoHS, n'itangazo rya REACH. Buri koherezwa ririmo icyemezo cy'uko bihuye n'imibare y'itsinda ishobora gukurikizwa.
Kuki wahitamo uruganda rw'imodoka zitwara abagenzi zo mu bwoko bwa DIN Rail Busbar Terminal Block zo mu Bushinwa?
Nzasubiza iki kibazo mu buryo butaziguye kuko amatsinda ashinzwe gutanga amasoko adusaba ibi buri cyumweru. Inganda zikora ibikoresho by'amashanyarazi zagize impinduka zikomeye mu myaka icumi ishize. Ubushobozi bw'inganda zo mu Bushinwa bwazibye icyuho cy'ubuziranenge ku bahanga mu by'i Burayi no muri Amerika - mu gihe zigumana inyungu iri hagati ya 30-50% ku giciro gikomoka ku gukora ibikoresho bihujwe, atari ukugabanya ibikoresho cyangwa ibizamini.
Dore icyo guhuza imiterere y'ikoranabuhanga bivuze mu bikorwa mu kigo cyacu: Dusuka ibikoresho byacu byo guteka mu nzu. Dusiga kashe ku byuma byacu by'umuringa bivuye ku mugozi wemewe wa C11000 ukomoka muri Jiangxi Copper (umwe mu bakora umuringa munini ku isi). Dukoresha imiyoboro yacu bwite yo guteranya ibyuma. Kandi dukomeza gukora laboratwari yacu yo gupima mu nzu ifite ibikoresho byo gupima amashanyarazi, micro-ohmmeters, kamera zipima ubushyuhe, n'icyumba cyo gupima cyihuse cy'amasaha 500.
Uku guhuza imiterere y’ibikoresho bito bikuraho ibice bitatu by’ibiciro - umucuruzi w’ibikoresho fatizo, umucuruzi w’ibice bito, n’umuhuza w’amasezerano - bikunze gushyirwa mu biciro by’ibikoresho bya terminal by’ikirango cy’Uburengerazuba (nagomba kumenya ko bikomeje gukorwa mu Bushinwa, gusa hakoreshejwe ikindi kirango).
Ku bakozi ba OEM n'abubatsi b'amapaneli, bashakira amasoko uhereye ku ruganda rwacu mu buryo butaziguye, ubukungu busobanura:

Uduce duto two ku mpera, plaque zo kugabanyamo ibice, n'imirongo yo kumenyekanisha muri rusange bihura n'ibirango bikomeye (Weidmüller W-Series, Phoenix Contact UK-Series) kuko ibi bipimo ari ibipimo ngenderwaho by'inganda - nubwo buri gihe tubasaba kugenzura imikorere ya mekanike n'icyitegererezo mbere yo kwiyemeza gukoresha ibintu byinshi.
Impamvu J-Guang ikenewe kuri DIN Rail Busbar Terminal Block yawe
Kuva mu 2010 twatangiye gukora ibyuma bihuza ibyuma n'ibihuza ibyuma bitanga umusaruro mu kigo cyacu kiri i Ningbo mu Bushinwa, tukaba tumaze imyaka 15 twibanda kuri iki cyiciro cy'ibicuruzwa. Ntabwo turi ikigo cy’ubucuruzi gitanga amasoko mu nganda zidasanzwe; turi uruganda.
Umurongo wacu w'ibicuruzwa bya DIN rail busbar terminal block ukubiyemo:
- Amanota ariho ubu: 80A, 100A, 125A, 150A, 175A, na 200A
- Ibipimo by'amashanyarazi: 600V na 1000V AC (UL iri kuri 600V; IEC ifite amanota 1000V)
- Interineti z'insinga: 1.5mm² kugeza 70mm² (AWG 16 kugeza 2/0)
- Imiterere y'inkingi: Inzira 2 kugeza 20, hamwe n'uburyo bwihariye buhari
- Ubwoko bw'itumanaho: Igikoresho cyo gufunga screw, imashini yo gusunika (≤16mm²), na stud/bolt (≥35mm²)
- Ibikoresho byo mu nzu: PA66 GF30, UL94 V-0, ubushyuhe bwo gukora -40°C kugeza +130°C
Buri gice gipimwa 100% hifashishijwe amashanyarazi mbere yo koherezwa — ntabwo cyapimwe ku buryo busanzwe, ntabwo cyapimwe mu buryo bw'imibare. Iyi ni politiki twashyize mu bikorwa mu 2015 nyuma yo kugaruka ku murongo umwe w’itumanaho ryavuye ku murongo wa "intermittent busbar-to-terminal" aho igerageza rya "batch" ryananiwe. Igiciro ni hafi $0.03 kuri buri gice mu igabanuka ry’ibiciro by’ibikoresho byo mu igerageza n’umurimo; agaciro kabyo ni zeru ku ibura ry’ibiciro bitewe n’inenge mu nganda mu myaka irindwi ishize.
