In order to obtain high dielectric silicone rubber (SR)-based nanocomposites, graphene (Gr) was added by ultrasonication and mechanical mixing for the preparation of a microporous structure. It discovered that Gr content expansion rate had great impact on cellular Based effects property, hybrid materials were prepared better properties appeared, as expected. For all samples, constant increased with until 3 wt% then decreased. When 2, reached 18.14 (1 kHz), which 55% higher than non-expansion...
Abstract Zinc oxide (ZnO) quantum dot (QD) decorated multi‐walled carbon nanotube (MWCNT) hybrid was utilized in the fabrication of high dielectric constant epoxy nanocomposites. Because shielding effect ZnO QD, well‐dispersed nanocomposites exhibit frequency insensitive as well greatly reduced loss. With only 1.5 wt% MWCNT addition, epoxy/MWCNT‐ZnO nanocomposite possesses 31 and loss low 0.01 at 1 kHz. In exhibits enhanced tensile properties. The role QD preparation property improvement...
With the rapid rise of new energy industry and its development all over world, there is a great market for submarine cable products. The world's first class AC 500kV cross-linked polyethylene (XLPE) insulated will soon be put into operation in "Zhoushan-Ningbo" interconnection project. Aging insulation materials after an important factor restricting safe XLPE cable. Taking consideration that frequency domain spectroscopy (FDS) nondestructive testing (NDT) method, this paper, changes...
A three-stage amplifier with hybrid active Miller enhancement compensation is proposed in this paper, which used for large to heavy load applications. The (HAMEC) composed of an amplified cascode capacitor block and a local network. sub-threshold transconductance enhanced (STEC) amplifying consists capacitor, effectively broadens the complex-poles frequency improves loop stability. novel slew rate structure also improve transient response under signal conditions. has been verified 0.18 μm...
Gas insulated switchgear (GIS) is increasingly developing toward high voltage and large capacity. During the operation of GIS, epoxy insulation components gradually age due to multiple issues electricity, heat, various environmental factors. Insulator aging reduces electrical strength mechanical insulators further leads GIS failure, therefore it becomes a crucial issue for with long running time, which determines operating life GIS. Thus, assessment an important work ensure safety...
Soft actuators driven by humidity and temperature have attracted widespread attention. These robots transform external stimuli into controlled deformation of the shape material. Here, we designed produced a series using plant parchment to achieve reversible under heating conditions. The difference in fiber arrangement direction inner surface structure leads anisotropy parchment, which causes large actuation at relative 100% (maximum curling curvature 4 cm <sup...
A local active sub-threshold transconductance enhancement compensation technique is proposed for driving ultra-large capacitive loads (C <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">L</sub> ). The used in outer loop of amplifier to enhance the cascode Miller effect. At same time, network introduced accurately eliminate first pole-zero pair and improves circuit stability. new slew rate structure also proposed, which can effectively increase...
Harvesting fog is a charming approach to alleviating the global water shortage crisis. However, it extremely challenging design collectors with high efficiency due scarce geometric driving structures. Herein, we develop 3D kirigami structure inspired by new corrugated structures in Bird's Nest Fern, which can be fabricated simple shearing and stretching. Its fog-harvesting increases external load, forming unique load responsiveness. The owns array configuration enhance flow velocity for...
In order to solve the current situation that there is no device for high voltage dielectric loss test in field which applied full-size GIS insulating spacer aging or substation service. So we develop insulator box can reduce electromagnetic interference of and fix stray capacitance. Compared with Schering Bridge, advantage comparator bridge analyzed, capacitance around measured calculated equivalently, its influence on circuit also analyzed. The shielding performance carried out by...
