Kev ntxiv dag zog txhawb nqa cov rwb thaiv tsev thiab txhim kho cov kev sib tw khiav ntawm kev foob
Cov neeg nuv ntses muaj 5 × 10³ω rwb thaiv tsev thiab 30% teeb liab atticuation nyob rau hauv high- zaus khiav taug kev. Yuav hloov kho li cas nrog insulating sib kho, thiab cov qauv yog dab tsi?
Hlau sib cuag ua rau rwb thaiv tsev tsis zoo. Kev Hloov Kho: ① 0.5mm Epoxy txheej (ntau dua lossis sib npaug nrog 20kv / hli tawg voltage); PTFE rwb thaiv tsev tsho hnav; ③ 80μm insulating pleev xim. Cov Qauv: Loj dua los yog sib npaug, tsawg dua lossis sib npaug nrog 5000 attraction, ntau dua lossis sib npaug ntawm 2000hz circuits. Ntau dua los yog sib npaug rau 95% lub zog khaws cia.
Cov neeg xam xaj insulated muaj 10⁶ω kuj nyob rau hauv 95% av noo ntau. Yuav ua li cas zoo foob / kua nplaum, thiab dab tsi yog noo noo {{}}} tiv taus cov tseev kom tsis taus?
Yoov nooit defulion rwb thaiv tsev. Optimization: ① 20% nano - sio₂ hauv kua nplaum; Biclicone sealant (5mm dav); ③ Polyimide Zaj Duab Xis. Yuav tsum muaj: ntau dua los yog sib npaug, tsawg dua los yog sib npaug ntawm 3MPA tev muaj zog, haum cov tunnels.
Dab tsi yog rwb thaiv tsev / lub zog kev ntsuam xyuas / qauv kev sim / qauv rau cov neeg foob, thiab yuav ua li cas ua cov neeg xam xaj cov nrog 2MPA)?
Kev ntsuam xyuas txheeb xyuas cov rwb thaiv tsev thiab kev ntseeg tau. Cov hau kev: ① rwb thaiv tsev tsis kam; Kev ntsuas lub zog zoo; ③ Thauj khoom- bearing test. Cov Qauv: Loj dua los yog sib npaug rau 10⁸ω, ntau dua lossis sib npaug nrog 3MPA, ntau dua lossis sib npaug nrog 300nks. Ua haujlwm: ① Tshem tawm cov kua nplaum qub, rov {{{}} phoo zuaj nto; ② Hloov kho epoxy (24h kho); ③ Kev Soj Ntsuam Tag Nrho.
Dab tsi yog rwb thaiv txawv qhov sib txawv rau 50/500 / 2000hz circuits, thiab ua li cas nrog mismatch?
Qhov sib txawv: ① 50Hz: ntau dua los yog sib npaug rau 10⁶ω, ntau dua lossis sib npaug ntawm 10kV; ② 500z: ntau dua los yog sib npaug rau 10⁷ω, ntau dua lossis sib npaug rau 15kv; ③ 2000z: ntau dua lossis sib npaug rau 10⁸ω, ntau dua lossis sib npaug rau 20kv. Lub hauv paus: Ntau zaus yuav tsum tau rwb thaiv tsev zoo dua. Mismatch: 50Hz Fishplate rau 2000hz: 25% Kev Ua Haujlwm, 8% Circuit Court tsis ua haujlwm.
Yuav ua li cas phim insulated rishceplates nrog siab - Lub Zog Bolts bolts, thiab ua li cas nrog kev sib txuam tsis zoo?
Kev txuam: ① Epoxy Fasters (3mm, ntau dua lossis sib npaug nrog 250MPA); ② 3mm ntev lub tes tsho ntev; ③ 220-250knim. Cov Qauv: Loj dua los yog sib npaug rau 10⁸ω Kuj, tsis muaj ntsia liaj qhov rooj xoob, tsawg dua los yog sib npaug rau 0.2mm hloov. Kev sib txig tsis zoo: Washer tawg: 10⁵ω Kuj, Kev Nyuaj Siab Loj.
