Izinzuzo of ibhodi le-epoxy ku-high-speed rail insulation

Ibhodi le-epoxy lilungele izimboni eziningi. Laba bakhiqizi abalandelayo bamapayipi e-epoxy bethula izinzuzo zabo ekufakweni kwesitimela esinesivinini esikhulu.

Isici esikhulu kunazo zonke sesitimela esinesivinini esikhulu siyashesha. Ngokusheshisa okuqhubekayo kukaloliwe onesivinini esikhulu, ukuhlola nokuma kubaluleka kakhulu. Inzwa isibe yisinqumo esingcono kakhulu sokulinganisa isivinini nokubeka indawo. Ukufakelwa kwemvelo kanye ne-dielectric nakho akunakugwenywa. Ngemuva kwezinqubo eziningi eziphindaphindiwe, ibhodi le-epoxy liwumkhiqizo ojwayelekile wokufakwa kwesitimela esinesivinini esikhulu.

I-Insulation: Ngokusho kwedatha, i-voltage yomzila wokuxhumana nomzila wesitimela wesivinini esikhulu ngu-27.5KV, okubonisa ukuthi i-voltage inkulu! Kodwa amandla okumelana nebhodi le-epoxy yilokhu: i-voltage yokuwohloka kwengqimba ehambisanayo (ku-90±2℃ kawoyela we-transformer): ≥40KV, akukho nokwenzeka kokuphuka nhlobo.

Ukumelana nokushisa okuphezulu nokuphansi: Ngokusho kwedatha efanelekile, izinga lokushisa elisebenzayo lebhodi le-epoxy lisukela ku-minus 100 degrees kuya ku-270 degrees (Baidu), futhi izinga lokushisa eliphansi kakhulu likajantshi wesitimela obanda kakhulu we-Harbin-Dalian liyi-minus 40 degrees. , onovivinyo olunzima emazingeni okushisa aphansi ezinto ezibonakalayo. Ibhodi le-epoxy elisolwayo lingasetshenziswa.

Ukumelana nomswakama: Isitimela esinesivinini esiphezulu sihlala sivezwa ngaphandle, akunakugwenywa ukuhlangana nemvula neqhwa, futhi ibhodi le-epoxy linokumelana okuhle nomswakama, kanye nezinga lokumuncwa kwamanzi ((D-24/23, ukujiya kwebhodi 1.6mm) ): ≤19mg).

Ukuzinza kwe-Dimensional: Ayithinteki kangako indawo ezungezile futhi ngeke ikhubazeke ngenxa yamazinga okushisa aphezulu naphansi.

Ukunqanda amalangabi: NgoJulayi walo nyaka nje, kwaqubuka umlilo esiteshini sikaloliwe esinesivinini esikhulu i-Changsha, kwashunqa intuthu enkulu, kwadala ukulahlekelwa okukhulu. Nakuba ungewona umlilo wesitimela esinesivinini esikhulu, kodwa futhi uyingozi kakhulu. Ngakho-ke, ukubambezeleka komlilo kubaluleke kakhulu kumzila wesitimela esinesivinini esikhulu, futhi kuyadingeka ukuvimbela izinkinga ngaphambi kokuba zenzeke. Ukusebenza kwe-flame retardant yebhodi ye-epoxy kufinyelela ku-94V-0 ejwayelekile.
