Niba icyumba cyicyuma cya anicyuma gishyushya amashanyarazibisaba gushira amarangi kumurongo biterwa nisuzuma ryuzuye ryubwoko bwihariye buturika, ibisabwa bisanzwe, hamwe nibisabwa.
I. Ibisabwa Byibanze Byibisobanuro Bisanzwe
1. GB 3836.1-2021 (Ibisabwa muri rusange kubikoresho muri Atimosifike iturika)
Ibipimo ngenderwaho bikubiyemo ibisabwa mubidukikije byumukungugu ariko ntibishyiraho amategeko ateganijwe kubijyanye no gutera amarangi ya lanish yo guteramo ibyumba byicyuma kubikoresho byo mucyiciro cya kabiri (nkaicyuma gishyushya amashanyarazi).
Kubikoresho byo mu cyiciro cya mbere (ibirombe by’amakara yo mu kuzimu), imbere y’ibyumba by’icyuma bigomba gushyirwaho irangi ridashobora kwihanganira arc (nk'irangi rya epoxy 1320 ya epoxy) kugira ngo hatabaho guturika gaze iterwa na arc. Nyamara, nta bisabwa byihariye biteganijwe ku bikoresho byo mu cyiciro cya II (ibidukikije bicukurwamo amakara nk'ibihingwa ngandurarugo, peteroli na gaze, n'ibindi).
2. Igishushanyo cyihariye cya Flameproof (Ex d) Ibikoresho
Ubuso bwo guhuza urugo rwa flameproof bugomba kuvurwa fosifati kandi bugashyirwaho amavuta yo kurwanya ingese (nkamavuta 204-1 arwanya ingese) kugirango habeho gufunga no kwangirika. Nubwo amavuta arwanya ingese afite ibintu bimwe na bimwe bikingira, ntabwo ari irangi ryihariye.
Niba hari imiyoboro igaragara cyangwa flashover ishobora kuba imbere mucyumba cyogeramo insinga, igishushanyo kigomba kubahiriza ibipimo (urugero, GB / T 16935.1) binyuze mumasoko no kureremba, aho gushingira gusa kumashanyarazi.
3. Ibisabwa byokwirinda kugirango umutekano wiyongere (Ex e) ibikoresho
Ibikoresho by’umutekano byongerewe imbaraga bigomba kwemeza ko nta kimurika mu gihe gisanzwe gikora, hamwe n’imikorere y’icyumba cy’icyumba cy’ibikoresho byifashishwa cyane cyane bishingiye ku bikoresho byifashishwa (nka ceramika, epoxy resin) hamwe no gukata ibyuma, aho kuba hejuru y’icyumba.
Niba ubuso bwibintu byangiritse byangiritse, bugomba gusanwa hifashishijwe irangi ryo murwego rumwe, ariko ntagisabwa ko urwobo rwose rushyirwaho.
II. Ibitekerezo bya tekiniki mubikorwa bifatika
1. Imikorere nimbibi zo gukingira Varnish
Ibyiza: Gukingira irangi birashobora kongera imbaraga zokwirinda hejuru (nko kurwanya arc no kwirinda kumeneka), bigatuma bikwiranye cyane nubushuhe bwinshi cyangwa ahantu h'umukungugu. Kurugero, gukoresha 20-30μm ya epoxy insulation irangi irashobora kongera igipimo cyo kugumana izirinda kugera kuri 85%.
Ingaruka: Gukingira irangi birashobora kugira ingaruka kubushyuhe. Kurugero, ibimenyetso biturikaamashanyaraziGuhindura ubushyuhe binyuze mu gukonjesha no kuzuza gaze ya inert. Gutera cyane birashobora guhungabanya ubushyuhe bwumuriro. Byongeye kandi, gusiga irangi bigomba gutsinda ibizamini byo kurwanya ubushyuhe bwo hejuru (urugero, hejuru ya 150 ° C) cyangwa birashobora kunanirwa.
2. Imyitozo yinganda nuburyo bwo gukora
Ibikoresho byahoze bitagira umukungugu: Ababikora benshi bakoresha primer yo kwirinda ingese (urugero, C06-1 icyuma gitukura cyitwa alkyd primer) imbere mucyumba cy’insinga, ariko gusiga irangi ntabwo ari itegeko. Kurugero, agasanduku runaka gashobora guturika moteri ikoresha agasanduku gakoresha "primer + arc-idashobora kwihanganira irangi rya magnetiki", bishimangira insulasiyo gusa.
Kongera ibikoresho byumutekano: Hashimangiwe cyane ku buryo bwo kwizerwa bw’imashini ihuza imiyoboro (nka anti-loosening terminal) no gutoranya ibikoresho byangiza, mugihe gutera umwobo bidakenewe.
3. Ibisabwa by'inyongera kuri Scenarios idasanzwe
Ibidukikije byangirika cyane (nk'ahantu h’inganda cyangwa ku nganda zikoreshwa mu nganda): Koresha irangi rirwanya ruswa (urugero, ZS-1091 ceramic insulating coating) kugirango harebwe imiti irwanya imiti.
Ibikoresho bikoresha ingufu nyinshi (urugero, hejuru ya 10kV): Irangi rya Gradient-umubyimba anti-corona ugomba gukoreshwa kugirango uhagarike gusohora igice.
III. Umwanzuro n'ibyifuzo
1. Ibiteganijwe gutera imiti
Gusa ibyumba byinsinga byibikoresho byo mucyiciro cya mbere (kubirombe byamakara yo munsi yubutaka) birasabwa gushyirwaho byanze bikunze irangi rirwanya arc.
Niba ibikoresho byongera imikorere yacyo idashobora guturika ukoresheje irangi ryerekana (urugero, kugirango wuzuze amanota menshi ya IP cyangwa irwanya ruswa), ibi bigomba kuvugwa neza mubyangombwa.
2. Ntabwo ari itegeko ariko bisabwa
Kubikoresho byo mu cyiciro cya II, birasabwa gukoresha irangi ryerekana niba ibintu bikurikira bihari:
Icyumba cyogeramo gifite umwanya muto, hamwe n’amashanyarazi cyangwa intera igenda yegera imipaka isanzwe.
Ubushuhe bukabije bwibidukikije (urugero, RH> 90%) cyangwa kuba hari umukungugu utwara.
Ibikoresho bisaba gukora igihe kirekire kandi biragoye kubungabunga (urugero, gushyingura cyangwa gushyirwaho kashe).
Birasabwa guhitamo ubushyuhe bwo hejuru (≥135 ° C) hamwe no gusiga irangi cyane (nk'irangi rya epoxy polyester), hamwe n'ubugari bugenzurwa hagati ya 20-30 mm kugirango habeho kuringaniza no gukwirakwiza ubushyuhe.
3. Gutunganya no kugenzura
Mbere yo gutera, urwobo rugomba kuvurwa umusenyi (icyiciro cya Sa2.5) kugirango harebwe amarangi ya firime.
Nyuma yo kurangiza, kurwanya insulasiyo (≥10MΩ) n'imbaraga za dielectric (urugero, 1760V / 2min) bigomba gupimwa, kandi ikizamini cyo gutera umunyu (urugero, 5% igisubizo cya NaCl, amasaha 1000 nta ngese) kigomba gutsinda.
Niba ushaka kumenya byinshi kubyerekeye ibicuruzwa byacu, nyamunekatwandikire!
