Mwisi yinganda zigezweho, intwari nyinshi ntizigera zigaragaza isura yabo. Ntabwo ari moteri yaka cyangwa bateri zivuga, ahubwo ni insinga zicecetse zitwara ingufu. Uyu munsi: umugozi UL3311, udasuzuguritse ariko ufite imbaraga zidasanzwe "Iron Man." Iguma kuba urutare rukomeye mubushyuhe bwo hejuru, kunyeganyega hamwe na acide kandi birashobora kugaragara mubintu byose uhereye kumashanyarazi kugeza kumasoko yo gusudira hamwe na sisitemu nshya yo kubika ingufu. Ntukirengagize iyi nsinga, nintwari itavuzwe itanga umutekano nibikorwa!
UL3311 "icyemezo cyamavuko": Imbaraga zingenzi munsi yubuziranenge
UL3311 ni uburyo bwo kumenyekanisha bwakozwe na Laboratoire ya Underwriters (UL) kubikoresho byo gukoresha ibikoresho (AWM), bihuye na UL 758 hamwe na CSA C22.2. Ifite voltage yagereranijwe ya 600V, ubushyuhe bwibanze bwa dogere 90 (kugeza kuri dogere 105 iyo ikoreshejwe ifatanije na UL3279), kandi ikoresha - imikorere ya thermosetting EPDM (Ethylene propylene diene monomer rubber).
Indwara ya EPDM iruta kure cyane PVC isanzwe: ni amavuta - irwanya, aside - irwanya, alkali - irwanya, abrasion - irwanya, ubushuhe - irwanya, kandi irwanya ibihumyo na ozone. Abayobora ahanini ni K K murwego rwo hejuru - guhinduka kwumuringa wambaye umuringa cyangwa amabati - umuringa usizwe, hamwe numurongo munini (amagana cyangwa ibihumbi n’ibipimo binini), bigatuma insinga ihinduka nka "noode", byorohereza kwishyiriraho ahantu hafunzwe cyangwa mubihe byunamye.
Ugereranije ninsinga zamashanyarazi zisanzwe murugo, UL3311 yerekana kuzamura cyane:
| UL3311 | UL1007 | UL1015 |
| 600V | 300V | 600V |
|
Impamyabumenyi 90-105 |
Impamyabumenyi 80 |
Impamyabumenyi 105 |
| EPDM kabuhariwe murwego rwo hejuru - kwizerwa imbere yimbere, ni urumuri rutambitse - retardant kandi verisiyo nyinshi ni halogen - kubuntu, irekura imyuka mike yangiza mugihe habaye umuriro. | PVC yoroheje, ibereye - igitutu n'umucyo - umutwaro. | Nibyimbye bya PVC, ariko kurwanya ibidukikije ntabwo ari byiza nka EPDM. |
Yatsinze ibizamini bya UL bikomeye kandi ikomeza imbaraga zidasanzwe za dielectric hamwe nubukanishi ndetse no mubihe bikabije. Niyo mpamvu yahindutse "icyatsi cyose" mu nganda.
"Jack - ya - yose - gucuruza" ku rugamba: Ibihe byukuri by'intwari UL3311
Umwanya wo gusudira ibikoresho
Mu mahugurwa yo gusudira aho ibicu biguruka, irangi ryamavuta riri hose, kandi ubushyuhe burahinduka cyane, insinga ya UL3311, ikoreshwa nkimashini yo gusudira, irashobora kwihanganira ubukana bwimashini hamwe nihungabana ryumuriro, bigatuma ihererekanyabubasha rihoraho no gukumira imiyoboro migufi itunguranye. Mugihe abasudira babira ibyuya byinshi, iyi nsinga irabarinda bucece ibintu.
Moteri iyobora hamwe nu nsinga imbere yibikoresho byamashanyarazi
Kuva kuri moteri yinganda kugeza kubucuruzi UPS idatanga amashanyarazi adahagarara ndetse nibice byimbere mubikoresho byo murugo, UL3311 itanga imiyoboro yizewe kandi yizewe. Kurambura kwayo bizamura umurongo winteko kandi birwanya gusaza no guturika igihe kirekire - ikoreshwa.
Ibihe bishya byingufu
Kuba ihari irahari hose: inverter izuba, ibikoresho byamashanyarazi yumuyaga, data center UPS, hamwe na sisitemu nini yo kubika ingufu -. Iyo paki nyinshi za batiri zahujwe, zigaragaza ituze munsi yinyeganyeza hamwe nihindagurika ryubushyuhe, bigatuma ihitamo kuri OEM nyinshi. Zeru - halogen irusheho guhuza hamwe nicyatsi kibisi, bigira uruhare mu ntego zo kutabogama kwa karubone.
Amashanyarazi mu bubiko
Tekereza amashanyarazi akoresha ububiko bugenda mububiko, aho paki ya bateri isaba kwizerwa hejuru - itangwa ryubu - umugozi wa batiri UL3311 uhuza neza. Ibipimo binini (nka 4 AWG cyangwa binini) byoroshye gukoresha amper amagana, kurwanya aside nibyiza kubiyobora - acide cyangwa bateri ya lithium, kandi umuyobozi wa Class K yoroheje yemerera abayishiraho guhunika kabili byoroshye.
Igishimishije, UL3311 ikoreshwa kenshi ifatanije na UL3279. Iyambere yibanze kuri dogere 90 yo kwizerwa, mugihe iyanyuma ishobora kugera kuri dogere 105. Hamwe na hamwe, bitwikiriye hafi ya byose - ibisabwa imbere. Ntibikwiriye gushyingurwa hanze cyangwa ultra - zikoresha amashanyarazi menshi, ariko ntagereranywa murwego rwo hejuru - imitako yimbere.
Kwibira cyane muri "tekinoroji" yikoranabuhanga: Niki gituma kiramba?
Reka dusuzume neza "ibihangange" bya UL3311:
-
Umuyobora: Hejuru - guhinduka umuringa wahagaritswe, AWG kuva kumurongo winsinga nziza kugeza kuri kcmil 1000 hejuru - insinga z'amashanyarazi, zihuza nibisabwa bitandukanye. Igishushanyo kinini cyo kubara kigabanya ingaruka zuruhu kandi kizamura imikorere.
-
Gukwirakwiza: ibikoresho bya EPDM, ubunini bwashyizwe hejuru ukurikije ibisobanuro (urugero, hafi santimetero 0,095 kuri gipima nini), bitanga uburyo bwiza bwo kurinda imashini, kwigunga amashanyarazi, no guhinduka. Kugera ku buringanire bwuzuye hagati yikiguzi nigikorwa, bihendutse kuruta silicone rubber cyangwa Teflon.
-
Ibikorwa by'ingenzi biranga imikorere: Kurwanya abrasion bihebuje, guhinduka, kurwanya imiti, n'imbaraga nyinshi za dielectric. Ubushyuhe ntarengwa bwa dogere -50, ntibizakomera no mubihe bikonje.
Inama zokwishyiriraho: Reba kumeza yubushobozi bwo gutwara mugihe uhitamo icyitegererezo (urebye gutandukana bitewe nubushyuhe bwibidukikije) hanyuma ukoreshe itumanaho rikwiye. Bika kure yizuba nibintu bikarishye, kandi urebe buri gihe imiterere yimiterere. Ugereranije n’insinga za PVC, ntabwo ikunda koroshya ubushyuhe bwinshi kandi ikagira igihe kirekire mu bidukikije, bigatuma iba insinga "ndende - iramba".
Kugura Ubuyobozi ninganda Kazoza: Reka UL3311 Kumurikira Imishinga Yawe
Ibicuruzwa nka Southwire, Cobra Wire, na Direct Wire bitanga ibicuruzwa bikuze, uhereye ku nsinga nziza za AWG za elegitoronike kugeza ku nsinga za batiri. Mugihe ugura, shakisha ikimenyetso cya UL hanyuma urebe nomero ya dosiye ya - utanga isoko kugirango wemeze kubahiriza umushinga.
Hamwe n'amashanyarazi (EVs, kubika ingufu, robotike, sitasiyo ya 5G), ibyifuzo byinsinga za - imikorere ya AWM bizaturika. Mugihe kizaza, barashobora kumurika mubikoresho byinshi byubwenge, bigahinduka "imiyoboro yamaraso" ihuza ingufu zicyatsi.
Byumvikane ko, ninsinga nziza zigomba gukoreshwa neza: irinde kurenza urugero kandi ukore neza buri gihe kugirango wongere agaciro. Umutekano niwo mwanya wambere wambere!
Epilogue: Icyubahiro kuri buri "Umuntu wicyuma" urabagirana bucece.
UL3311 irashobora kutagira isura nziza, ariko imikorere yayo yizewe yatsinze injeniyeri. Ihanganira ubushyuhe bwinshi, yihanganira kunyeganyega, kandi itanga inkunga ikomeye mugihe gikomeye - cyerekana neza umwuka winganda. Ubutaha nubona ibikoresho byamashanyarazi bikora neza cyangwa imashini yo gusudira ikora neza, ibuka inkuru iri inyuma yiyi nsinga.
