ترانسفورماتورهای قدرت از اجزای اصلی شبکه تامین انرژی الکتریکی می باشند که عملکرد قابل اطمینان ترانسفورماتورها یکی از فاکتورهای مهم و تعیین کننده در تامین انرژی الکتریکی محسوب می شود. در نتیجه بررسی و مانیتور عملکرد ترانسفورماتورها در شبکه و همچنین عیب یابی این ترانسفورماتورها غیرقابل اجتناب و ضروری می باشد. به طور کلی عایق های مایع در صنعت فشار قوی کاربردهای متفاوتی دارند که مهمترین وظیفه آنها...
15 صفحه اولInduced crystallization porosity and properties of sintereds diopside and wollastonite glass-ceramics
diopside (CaO·MgO·2SiO2) and wollastonite (CaO·SiO2) glass-ceramics, forming ∼60% crystal phase and ∼40% albite-like Na2O·Al2O3·6SiO2) residual glass were studied. Two other diopside glass-ceramics with higher Na2O and Al2O3 content were also investigated. The phase formation was estimated by DTA, XRD and pycnometry, while the densification process was evaluated by porosity variations, ilatomet...
متن کاملInvestigation of crystallization and sinterability properties of BaO-Al2O3-SiO2 glass-ceramics containing K2O and B2O3
BaO -SiO2-Al2O3 glass ceramics containing K2O and B2O3 were prepared using conventional melting of powered batches, quenching in water and crystallization of sintered glass. XRD patterns introducehexacelsian and celsian as two major crystallized phases in sintered glass-ceramics. Presence of K2O enhances crystallization of hexacelsianin comparison withB2O3.Observations showed sintering temperat...
متن کاملProperties of sintered glass-ceramics in the diopside–albite system
A series of sintered glass-ceramics belonging to the system diopside–albite, forming by surface crystallization 30, 50 and 65% diopside, was investigated. In order to study the effect of bulk crystallization on the sintering a 0.7% of Cr2O3 as nucleation agent was added in one of the compositions. The crystallization was evaluated by DTA and density measurements and the degree of densification ...
