2. Uburyo bwo gusenya hamwe na optimizme ya epoxy resin insulation
Epoxy resin insulation nuburyo bukomeye, kandi imbaraga zo kumeneka imbaraga zikomeye zirenze iz'amazi na gaze. gusenyuka gukomeye
Ikiranga nuko gusenya umurima imbaraga zifite isano ikomeye nigihe cya voltage ibikorwa. Muri rusange, gusenyuka kwigihe cyibikorwa t Gusenyuka kwigihe cyibikorwa t hours amasaha menshi ni amashanyarazi yamashanyarazi. Nubwo ubu buryo butatu bwo gusenyuka butandukanye, ingaruka zo gusenyuka nuko uburyo bukomeye bwangiritse burundu. Iyo ukoze amashanyarazi inshuro nyinshi kwihanganira ikizamini cya voltage kuri switchgear, mugihe cyo kuzamura kimwe kimwe cyumubyigano wikizamini ukoresheje voltage igenzura, ibice byavuzwe haruguru byerekana insimburangingo hamwe na nyirubwite, usibye ko byavuzwe haruguru voltage ikomezwa kuminota 1 nyuma ya voltage yazamutse neza. Usibye gusenyuka, mugihe igice icyo aricyo cyose kiri mubikorwa byo kuzamura bitewe no kutagira intege nke, gusenyuka ni ako kanya, kandi gusenyuka bigomba gufatwa nkumuriro w'amashanyarazi. Iki kibazo gikunze kugaragara kuri epoxy resin irinda ibice. Ibikurikira nurugero rwa 40.5 kV vacuum circuit breaker ikomeye-ifunze pole kugirango isesengure iki kibazo.
Ibyo bita pole-bifunze cyane bivuga igice cyigenga kigizwe na vacuum interrupter na / cyangwa imiyoboro iyobora hamwe na terefone zayo zapakishijwe ibikoresho bikomeye. Kubera ko ibikoresho byayo bikingira cyane cyane epoxy resin, ingufu za silicone reberi hamwe na adhesive, nibindi, hejuru yinyuma ya vacuum interrupter iba ikikijwe kuva hasi kugeza hejuru ukurikije uburyo bukomeye bwo gufunga. Inkingi ikorwa kuri peripheri yumuzingi nyamukuru. Mubikorwa byo kubyaza umusaruro, inkingi igomba kwemeza ko imikorere yumuvuduko wa vacuum itazagabanuka cyangwa ngo itakare, kandi ubuso bwayo bugomba kuba buringaniye kandi bworoshye, kandi ntihakagombye kubaho ubunebwe, umwanda, ibibyimba cyangwa imyenge bigabanya imiterere yamashanyarazi nubukanishi. , kandi ntihakagombye kubaho inenge nkibice. . Nubwo bimeze gurtyo, igipimo cyo kwangwa 40.5 kV yibicuruzwa bifunze bifunze neza biracyari hejuru cyane, kandi igihombo cyatewe no kwangirika kwa vacuum ni umutwe kubice byinshi byinganda. Impamvu nuko igipimo cyo kwangwa giterwa ahanini nuko inkingi idashobora kuzuza ibisabwa. Kurugero, muri 95 kV 1 min yumurongo wumuriro wihanganira ikizamini cya voltage insulation, hariho amajwi asohora cyangwa ibintu byo gusenyuka imbere muri insulation mugihe cyizamini.
Duhereye ku ihame ryo gukwirakwiza ingufu za voltage nyinshi, tuzi ko inzira yo kumeneka amashanyarazi yikintu gisa nki cya gaze. Electron avalanche ikorwa ningaruka ionisation. Iyo electron avalanche ikomeye cyane bihagije, imiterere ya dielectric lattice irasenywa kandi gusenyuka biraterwa. Kubikoresho byinshi byokoresha insulasiyo bikoreshwa mugufunga-gufunga bikomeye, voltage nini cyane uburebure bwikibice ishobora kwihanganira mbere yo gusenyuka, ni ukuvuga imbaraga zavutse zo mumirima, ni hejuru cyane, cyane cyane Eb ya epoxy resin ≈ 20 kV / mm. Nyamara, uburinganire bwumuriro wamashanyarazi bugira uruhare runini kumiterere yimiterere yikigereranyo gikomeye. Niba hari amashanyarazi akomeye cyane imbere, kabone niyo ibikoresho byabigenewe bifite umubyimba uhagije hamwe n’imisemburo ihagije, byombi ikizamini cyo guhangana n’umuvuduko hamwe n’ikizamini cyo gusohora igice cyatsinzwe iyo uvuye mu ruganda. Nyuma yigihe cyibikorwa, kunanirwa kwangirika birashobora kugaragara kenshi. Ingaruka z'umuriro w'amashanyarazi waho zirakomeye cyane, kimwe no gutanyagura impapuro, guhangayikishwa cyane bizashyirwa kuri buri gikorwa cyibikorwa, kandi igisubizo nuko imbaraga zitarenze kure imbaraga zimpapuro zishobora gutanyagura byose impapuro. Iyo umurima w'amashanyarazi ukomeye cyane mukarere ukora kumashanyarazi mumashanyarazi, bizatanga "umwobo wa cone", kuburyo ibikoresho byokwirinda bigenda bisenyuka buhoro buhoro. Nyamara, mubyiciro byambere, ntabwo ingufu zisanzwe zisanzwe zihanganira voltage hamwe nigeragezwa ryikizamini cyo gusohora igice nticyashoboraga kumenya akaga kihishe, ariko kandi ntanuburyo bwo gutahura bwo kubimenya, kandi birashobora kwemezwa gusa nuburyo bwo gukora. Kubwibyo, impande zumurongo wo hejuru nu munsi zisohoka zomugozi zifunze zifunze zigomba guhindurwamo uruziga ruzengurutse, kandi radiyo igomba kuba nini ishoboka kugirango ikwirakwizwa ryumuriro w'amashanyarazi. Mugihe cyo kubyaza umusaruro inkingi, kubitangazamakuru bikomeye nka epoxy resin na rubber silicone reberi, bitewe ningaruka zo guhuza agace cyangwa itandukaniro ryijwi kumeneka, imbaraga zumurima zishobora kuba zitandukanye, numurima wo gusenyuka munini agace cyangwa ingano birashobora kuba bitandukanye. Kubwibyo, uburyo bukomeye nka epoxy resin bigomba kuvangwa neza mukuvanga ibikoresho mbere yo gufunga no gukira, kugirango bigenzure ikwirakwizwa ryimbaraga zumurima.
Muri icyo gihe, kubera ko uburyo bukomeye butari bwo-kwisubiraho, inkingi ikorerwa voltage nyinshi. Niba igikoresho gikomeye cyangiritse igice munsi ya buri gipimo cyikigereranyo, munsi yingaruka ziterwa na voltage nyinshi, ibi byangiritse igice bizaguka kandi amaherezo biganisha kumeneka. Kubwibyo, inkingi yimikorere ya pole igomba kuba nini kugirango irinde kwangirika kuri pole na voltage yageragejwe.
Byongeye kandi, icyuho cyumwuka cyatewe no gufatana nabi kwitangazamakuru ritandukanye rikomeye mu nkingi ya pole cyangwa ibyuka bihumeka mu buryo bukomeye ubwabwo, bitewe n’umuvuduko wa voltage, icyuho cy’ikirere cyangwa ikinyuranyo cy’ikirere kiri hejuru kuruta icy'ikomeye giciriritse bitewe nimbaraga zo murwego rwo hejuru mukirere cyangwa ikirere. Cyangwa gusenyuka kumurima imbaraga zibibyimba biri hasi cyane kurenza ibinini. Kubwibyo, hazabaho gusohora igice mubice byinshi muburyo bukomeye bwa pole cyangwa gusenyuka kumyuka yo mu kirere. Kugira ngo iki kibazo gikemuke, biragaragara ko wirinda ko habaho icyuho cy’ikirere cyangwa ibibyimba byinshi: surface Ubuso bwo guhuza bushobora gufatwa nkubuso bumwe bwa matte (ubuso bwa vacuum interrupter) cyangwa ubuso bwurwobo (hejuru ya reberi ya silicone), na Koresha ifatika yumvikana kugirango ihuze neza ubuso buhuza. MaterialsIbikoresho byiza cyane nibikoresho byo gusuka birashobora gukoreshwa kugirango habeho gukingirwa gukomeye.
