Power transformer is one of the most important power transmission equipments in the power system. The reliability and operational efficiency of power system is directly related to its performance and quality. The insulation paper used in oil-immersed transformer cannot resist high temperature, and the significant diff…
because of the existence of non-linear loads,they will be inpouring a lot of harmonic current to the power system,in order to restrain harmonic,we have to take relevant measures to restrain. This paper introduces three measures of harmonic restraint firstly, expounds the active power filter, and then it analyses the w…
Fractional-slot concentrated-winding has a lot of advantages such as low cogging torque, short end winding and high power density, but the slot fill factor is relatively small with preformed windings when the slot number of machine is small. This paper explores un-even winding turns for double-layer FSCW machines to a…
An anisotropic conductive film (ACF) is a thin adhesive epoxy layer that is widely used to connect circuits in highly-integrated electronic devices. To bind two electric circuits, an ACF is pasted between the circuits and pressed with an optimum pressure so that the joints can be electronically connected. For the curi…
This study describes the absorption, transmission and reflection spectra of Ag/Ti/SiO2balls/glass and CHCl3:Alq3/Ag/Ti/SiO2balls/glass structures with 200 ~ 650nm SiO2balls, respectively. The enhanced fluorescence in a CHCl3:Alq3 (60nm)/Ag (70nm) / Ti (5nm) /SiO2balls /glass structure using by surface plasmons when th…
The quaternary TixZr1-xMnFe gettering alloys (x =0, 0.1, 0.2, 0.3 and 0.4) were synthesized successfully by arc melting and their phase structures along with microstructures had been investigated by optical microscopy (OM), scanning electron microscopy (SEM), X-ray diffraction (XRD) and transmission electron microscop…
Studying the armor-piercing effect of armor-piercing bomb that attacks aluminum target is essential, because the target can be considered the simulation of the actual fight equipment. Based on the hypothesis about building the fraction field, the armor-piercing effect of armor-piercing bomb is analyzed, and the veloci…
Summary Aiming at the development of robust and durable aromatic polyethers that can be doped with phosphoric acid and still maintain their mechanical integrity at temperatures higher than 200 °C, we focused on the optimization of the chemical process for oxadiazole (OXD) cross‐linked membranes through cyclodehydratio…
With high optical transparency and electrical conductivity, ITO thin films were fabricated by DC magnetron sputtering. Based on orthogonal test table L18 (35), the effects of process parameters included water partial pressure, work pressure, substrate temperature, oxygen flow rate and sputtering power, on the optoelec…
This paper is part 2 of a two paper series on electrical machine iron loss predictions. The part 2 paper is focused on application of, and experimental data comparisons for, a new and unique method for predicting machine iron losses using transient finite element methods (FEM). A significant difference of the new meth…
In situ environmental transmission electron microscopy (ETEM) observation was used to reveal Sn inside Sn-filled carbon nanofibers (CNFs) during heating. Before and during heating, the Sn was covered completely by CNFs. The volume of Sn present in the Sn-filled CNFs gradually decreased during heating, with new Sn part…
Temperature dependent photoluminescence (PL) properties of ZnO thin film prepared by sol-gel route were investigated. The excitonic-related emission peak at 3.336 eV dominates the spectra, and is attributed to the recombination of excitons bound to structural defects (DBX). Moreover, its thermal activation energy is 5…
The paper is talked about a high power active power filter. The main circuit topology adopts a three-phase three-line voltage source converter,which is constituted by three H-bridges. The delta connection H-bridge topology has a good ability to compensate unbalanced load and fulfills the requirements of energy compens…
CFRP (Carbon Fiber Reinforced Plastic) is functional material that is begin to be widely used in commercial aircraft, vehicle and etc. Investigation regarding the mechanical strength of CFRP is widely investigated. However, the electrical characteristics of this type of material are still not well known. Understanding…
Using the experimental method for water medium interval target how to affect the ability of the jet penetration degree is determined. In order to verify the target interval between target and target medium effect on the jet penetration, with a shaped charge respectively on the interval of air and water medium target p…
The polyfunctional organic compounds 2- hydroxymethyl -1,4- butanediol (trihydric alcohol) and toluene diisocyanate -2, 4- diisocyanate (TDI) were taken as the raw materials in this study. A polyurethane dendrimer was synthesized by utilizing the difference in the reaction activity of two isocyanate groups of TDI at d…
Morphology of mesoporous silica has been transformed from spherical to ellipsoidal form due to the structure directing role of alpha-cyclodextrin. The product exhibits a well ordered pore structure as deciphered from the SAXRD and TEM measurements. SEM studies indicate that the samples without alpha-cyclodextrin posse…
