Uyini umehluko wokusebenza phakathi kwezesekeli zekhebula ezincibilika kalula kanye nezesekeli zekhebula ezincibilika kalula?

1, Uphawu

Njengoba iningi lezesekeli zekhebula lingaphandle, limbozwe ngqo nakwezinye izindawo, ukungangeni manzi kanye nokumelana nomswakama sekungenye yezihluthulelo zokuqinisekisa ukuphepha kwezesekeli zekhebula, futhi umsebenzi wokuvala kanye nendlela okufanele kucatshangelwe.

Njengamanje, kunezindlela ezimbili zokuvala ngokuvamile:

Enye iwukuvala nge-asphalt noma i-epoxy resin, inqubo ayihlelekile, kunzima ukuyilawula, futhi ayivumeli ukuvikelwa.

Enye indlela entsha ukusebenzisa i-sealant ene-elastic ephezulu, elula ukuyisebenzisa, ethembekile ekusebenzeni kwayo, futhi elula ukuvikela imishini, okuye kwaba yinto esetshenziswa kakhulu. Ukuze sisebenzise le ndlela entsha, kumele siqale sicabangele umsebenzi we-sealant. Ngoba ikhwalithi nomsebenzi we-sealant kuthinta ngqo umsebenzi wokuvala wejoyinti.

Izesekeli zekhebula lamandla ezincibilika ngokuphelele empeleni ziyizesekeli zekhebula ezinwebekayo, okungukuthi, kusetshenziswa ukunwebeka kwerabha ye-silicone ewuketshezi noma eqinile, yandisa efektri kusenesikhathi, ubeke ipulasitiki kanye nemichilo yokusekela, bese ususa imichilo yokusekela uye endaweni ekhethiwe ukuze ifushaniswe ngokwemvelo.

Lolu hlobo lwekhono luyindlela yokunciphisa okubandayo, futhi lolu hlobo lwesesekeli luyisesekeli sekhebula esinciphayo esibandayo. Ngakho-ke, lesi sesekeli sekhebula esinciphayo esibandayo sinokunwebeka okuvelele, okungavimbela ikhebula ukuthi likhule futhi linciphe ngenxa yendawo engalingani yomoya kanye nomthwalo wokusebenza ongalingani wekhebula, okungukuthi, isikhala sokuvikela esidalwe ukuphefumula kwekhebula.

Ububi bezesekeli zekhebula ezincipha ukushisa ukuthi aziguquguquki futhi azikwazi ukuphefumula ngekhebula.

Ngakho-ke, izesekeli zekhebula ezincibilika ngokuphelele ezibandayo ziyisinqumo esingcono kakhulu ezindaweni ezinomehluko omkhulu wokushisa kanye nemiphumela emikhulu yesimo sezulu kanye nemvelo!

2, Ukuvikela Ukushisa

Izidingo zokufakwa kokushisa kwezesekeli zekhebula kufanele zihlangabezane nokufakwa kokushisa phakathi kwezigaba kanye nokufakwa kokushisa okuphambene.

Ukufakwa kokushisa okuhlobene yirabha ye-silicon kanye nezinto zokufakwa kokushisa ezinciphayo. Ngokuvamile, umsebenzi wokufakwa kokushisa usekelwe ekuhlosweni kokufakwa kokushisa kweyunithi yezinto ezibonakalayo, futhi ubukhulu bezinto ezihlanganisiwe buhlangabezana nezidingo.

Izesekeli zekhebula ezincibilika kalula, inkomba yokusebenza evamile ingu-24kV/mm, kanti ubukhulu bokusebenza obuhleliwe kufanele buhlangabezane nobukhulu obungu-12mm, obungamelana nokuhlolwa kokushaqeka kombani kanye nogesi ongaphezulu.

Izesekeli zekhebula ezinciphayo ngokushisa zenziwe ngezinto ezahlukahlukene ezihlanganisiwe futhi zinomsebenzi wokunciphisa ukushisa ngemva kokucutshungulwa kwemisebe. Inkomba yokushisa yeyunithi ingu-1.8-2.0kV/mm, futhi ubukhulu obuhleliwe bungu-3-4mm obukhulu kunezinto zerabha ze-silicone. Ukushisa okuhlobene kuyibanga eliphephile lokuvimbela ukushaja ukuthi kungakhuphuki kusuka kumandla aphezulu kuya kumandla aphansi.

Izinto zerabha ze-silicone ezincibilikayo ezibandayo zinokunwebeka okuhle kakhulu. Uma nje ukuhlela kunengqondo, ukuqina kwayo okuqinile kungakwanelisa amandla okubamba. Kungakhathaliseki ukuthi indawo ikhula ngokushisa noma incibilikayo ebandayo, izesekeli zekhebula ezincibilikayo ezibandayo ziqinisekisa ukuthi ikhebula ligonwe ngokuqinile ukuvimbela ukuhogela umswakama nokuqinisekisa ibanga eliphephile langaphakathi lokuhamba. Ngesikhathi esifanayo, ngokwethiyori, ibanga langaphakathi lokukhuphuka lazo zonke izesekeli zekhebula ezincibilikayo ezibandayo lingu-70mm kuphela, kodwa ngenxa yezizathu zokuphepha, ibanga lokusebenza elihleliwe lisengu-90mm.

Izinga lokushisa elifinyeziwe lezesekeli zekhebula elincibilika ngokushisa lingu-100℃-140℃. Kusemishini kuphela lapho izinga lokushisa lingahlangabezana nezimo zalo zokufinyezwa. Uma izinga lokushisa liphansi, ngoba i-coefficient yokwandisa ukushisa kwekhebula ihlukile kweyezinto ezincibilika ngokushisa, indawo engaphansi kuka-80°C ingahlukana, ngakho-ke kuzovela imifantu, okuvumela amanzi nomswakama ukuthi kungene ngaphansi kwesenzo sokuphefumula, ngaleyo ndlela kubhubhise ukufudumala kohlelo. Lokhu kuyiphutha elincane lezinto ezincibilika ngokushisa.

3, Insimu kagesi

Lapho kucutshungulwa insimu kagesi yezesekeli zekhebula ezincibilika kalula, kusetshenziswa izindlela eziningana ukushintsha ukusabalala kwensimu kagesi ngokusebenzisa ama-stress cones, futhi kusetshenziswa izimo ezithile kanye nokucubungula okunembile kwe-R-viewpoint. Le ndlela ilula kakhulu ukuyilawula nokuyihlola futhi ingaqedwa efektri.

Indlela yokwelapha insimu kagesi yezesekeli zekhebula ezincishiswa ukushisa ukushintsha ukusatshalaliswa kwensimu kagesi ngamapharamitha aqondile. Kuyadingeka ukuthembela kumapharamitha amabili abalulekile:

Ukumelana nevolumu, 108-11Ω.

I-dielectric constant ingu-25.

Ngenxa yenqubo yokukhiqiza engahlelekile kanye nezinguquko ezinkulu ezicini zemvelo, kunzima kakhulu ukulawula ukuzinza kwamapharamitha, okuzothinta ukuzinza kwekhwalithi yomkhiqizo.

Ngakho-ke, izesekeli zekhebula ezinciphayo ezibandayo kanye nezesekeli zekhebula ezinciphayo ezishisayo zihlukile ngokuphelele enkambisweni ngokwayo. Ukusebenza ngaphansi kwezimo ezijwayelekile, kokubili kuhlangabezana nezidingo zokuphepha. Kodwa-ke, njengoba indawo ishintsha, ukuncipha okubandayo empeleni kunenzuzo kakhulu kunokuncipha kokushisa. Yiqiniso, intengo yokuncipha okubandayo iphakeme kakhulu kuneyokuncipha kokushisa.
