Gushyirahoepoxy resin inyura mu nkutani imikorere y'amashanyarazi isobanutse neza kandi igenzurwa neza, ahanini igabanyijemo ibintu bibiri: ishyirwamo (ishyirwamo icyarimwe mu gihe cyo kubaka urukuta) n'ishyirwamo (ishyirwamo nyuma yo gushingwa urukuta). Izi zikurikira ni intambwe rusange zo gushyiraho n'ingingo z'ingenzi zishingiye ku mahame ngenderwaho y'inganda (nka GB 50149-2010, DL/T 5221-2016).
I. Intambwe Rusange zo Gushyiraho
1. Gutegura mbere yo gushyiraho
Igenzura ry'ibipimo: Emeza ko intera y'amashanyarazi, umuvuduko w'amashanyarazi, n'intera y'ubujyakuzimu bw'agace k'ubujyakuzimu bihuye n'igishushanyo mbonera, kandi urebe niba hari icyuho cyangwa ibyangiritse ku ishusho.
Gupima no gushyiramo: Koresha umurongo wa laser cyangwa ingwa kugira ngo ugaragaze umurongo wo hagati w'urukuta kugira ngo umenye neza aho umwobo uherereye kandi wirinde guhangayika kuri busbar cyangwa insinga iyo bishyizwemo nyuma.
Gutunganya imyobo: Ubusanzwe umurambararo w'imyobo uba munini hagati ya mm 5-10 ugereranije n'umurambararo w'inyuma w'imyobo kugira ngo ibikoresho bifunga bishobore guhindurwa no kuzuza. Inkombe z'imyobo zigomba guhindurwa neza kandi hagakurwaho uduce duto kugira ngo hirindwe kwangirika k'insinga cyangwa ubuso bw'imyobo.
2. Gutera ibihuruGushyiraho no Gufunga Ibikoresho
Uburyo bwo Gufata: Ku bushing bwa epoxy resin hamwe n'ibyuma bifunganye (nk'ibyuma bifunganye bya aluminiyumu), ubusanzwe bukoreshwa mu gufunga bushing ku mpande zombi z'urukuta. Igihe cyo gufunga gisabwa ni ≤ 300mm kugira ngo bushing idacika intege mu gihe cyo gukora vibration.
Gufunga: Iyi ni intambwe y'ingenzi mu gukumira amazi, kwirinda inkongi, no gukumira imbeba.
Gushyiramo Icyuho: Icyuho kiri hagati y’urukuta n’ikuta kigomba kuzuzwamo putty idashya cyangwa sealant idashya, gifite ubugari bwa ≥ 20mm kugira ngo habeho icyuho gikomeye kandi kidashya.
Uburyo bwo kuvura amazi: Ku bijyanye no kwinjira mu rukuta rwo hanze cyangwa ahantu hatose, impera y'inyuma y'urukutagukururaigomba kuba ihengamye hasi kuri 15° – 30°, kandi hagashyirwaho igipfundikizo kidapfa amazi kugira ngo amazi y'imvura adasubira inyuma.
3. Gushyiramo no guhuza icyuma gitwara amashanyarazi
Uburinzi bwo Gushyiramo: Mbere yo gushyiramo imigozi cyangwa insinga, reba niba urukuta rw'imbere rw'ingobyi rumeze neza. Ku nsinga, ni byiza gushyiramo umuyoboro urinda (nk'umuyoboro wa corrugated) ku gice cyo gushyiramo kugira ngo hirindwe ko impande zityaye zakwambura urwego rwo gukingira.
Gukomeza guhuza: Mu gihe uhuza terminal, amaboliti agomba gufungwa ku muvuduko usanzwe kugira ngo wirinde gushyuha bitewe n'uko nta kintu gihuye nacyo. Nyuma yo guhuza, reba niba impeta yo gufunga imeze neza kugira ngo wirinde ko amazi yinjira.
4. Isuzuma nyuma yo gushyirwaho
Ikizamini cyo Gukingira Ubwinshi: Nyuma yo gushyiraho, ubushobozi bwo kwirinda gukingira ubwinshi bugomba kugeragezwa hakoreshejwe megohmmeter ya 2500V. Agaciro kemewe ubusanzwe ni ≥1000MΩ (cyangwa hakurikijwe ibipimo byihariye).
Ikizamini cyo kwihanganira Voltage: Ku biti bifite voltage nyinshi (nk'ubushyuhe bwa 10kV no hejuru yabyo), hagomba gukorwa ikizamini cyo kwihanganira voltage yihuta (urugero, gupima voltage ya 10kV bishyirwa kuri 42kV/iminota 5 nta gucikagurika).
II. Amabwiriza y'ingenzi yo kwirinda
Nta gukomanga cyane: Nubwo epoxy resin ifite imbaraga nyinshi, ubushobozi bwayo bwo guhangana n’ingaruka ntabwo ari bwiza nk’ubw’icyuma. Mu gihe cyo kuyishyiraho, birabujijwe cyane gukubita igice cy’icyuma ukoresheje inyundo cyangwa ibindi bintu bikomeye kugira ngo hirindwe ko uduce duto tw’icyuma mu gice cy’imbere cy’icyuma gikingira imbere twangirika, ibyo bikaba byatera gusohora igice cy’amazi.
Gukumira no Gusukura Ubushuhe: Mbere yo gushyiraho, hanagura imbere n'inyuma by'agace k'ubushuhe ukoresheje alcool idahumanya kugira ngo urebe neza ko nta mukungugu cyangwa amavuta birimo. Mu gihe ukorera mu gihe cy'ubushuhe, fata ingamba zirinda ubushuhe kugira ngo wirinde ko ubushuhe bwagira ingaruka ku mikorere y'ubushyuhe.
Inyongera yo Kwagura no Kugabanya: Ku bidukikije bifite aho bihurira cyangwa ubushyuhe bwinshi, hagati y’aho bihurira n’aho bihurira hagomba kuba hasigaye umwanya wa 10-15mm wo kwagura no kugabanya, cyangwa hagashyirwaho icyuma gitanga ubushyuhe kugira ngo hirindwe ko ibidukikije bihinduka bitewe no kwaguka no kugabanuka k’ubushyuhe.
Ibisabwa mu gusiga hasi: Niba icyuma gikingira cyangwa icyuma gikingira hasi, kigomba kuba gifite icyuma gikingira hasi, kandi ubushobozi bwo gusiga hasi bugomba kuba ≤4Ω kugira ngo amashanyarazi aturutse ku butaka akurweho.
III. Gukoresha ahantu hadasanzwe
Gushyiramo: Mbere yo gusuka urukuta rwa sima, uruziga rugomba gushyirwamo. Muri iki gihe, hagomba kwitabwaho cyane uburyo uruziga rushyirwamo neza kugira ngo hirindwe ko uruziga rutembera mu gihe cyo gusukura. Impera zombi z'uruziga zigomba kuva ku rukuta ho hejuru ya mm 50 kugira ngo byorohereze kuzifunga mu cyiciro cya nyuma.
Gushyira hanze: Uduti two hanze akenshi tuba dufite utundi duti turwanya umwanda. Mu gihe cyo gushyiraho, shyira umutima ku cyerekezo cy'utundi duti (ubusanzwe tumanuka), kandi usukure umwanda ku tundi duti buri gihe kugira ngo wirinde ko ivumbi rikomeza kwiyongera.
Inama z'umutekano: Imirimo yo gushyiraho igomba gukorwa mu gihe nta ngufu zihari, kandi hagomba kumanikwa icyapa cy'umuburo kivuga ngo “Ntufunge”. Gushyiraho imiyoboro ifite ingufu nyinshi birasabwa kugira ngo bikoreshwe n'abahanga mu by'amashanyarazi b'inzobere.
