The energized icing tests for five kinds of 220 kV composite insulators with and without the grading ring (GR) at high voltage (HV) end are performed in artificial climate chamber. Combining numerical simulations electric field (E-field), differences between influence GR shed configuration on ice characteristics flashover performance compared analyzed. Results indicate that can improve both growths E-field distributions near HV end. improvements voltages under light degree is relatively...
The shed configuration has obvious effects on the flow field characteristics and electric distributions around composite insulators, then impacts their icing flashover performance. In this study, AC comparative tests for 12 types of 220 kV insulators with different configurations under non-energized energized ice accumulation conditions are conducted in artificial climate chamber. influences voltages arc paths analyzed. Results indicate that increase stress, both path ratio air gap gradually...
Abstract In an era of significant energy consumption by commercial building HVAC systems, this study introduces a Deep Reinforcement Learning (DRL) approach to optimize these systems in multi‐zone buildings, targeting reduced usage and enhanced user comfort. The research begins with the development model for considering complexity uncertainty system parameters. This informs creation novel DRL‐based optimization algorithm, which incorporates multi‐stage training multi‐agent attention...
The grading ring (GR) can adjust the potential distribution along composite insulator and reduce electric field (E-field) strengths near its end fittings. However, little research has been conducted about effects of GR on insulation performance insulators under icing condition. Therefore, ac flashover two kinds 220 kV different arrangement patterns are tested in artificial climate chamber. Combining with numerical simulation, analyzed. results indicate that when is installed at high voltage...
Effect of low damage strip process on SiGe surface state under ICP and MARS mode is studied in this paper. FG-based current density around 10 times lower than that mode. Ge rich interface found between Si-O layers after treatment process. Valence can be tailored by various gas composition plasma activation Oxidation thickness valence are different for the sample with conditions, including
Surface air cooler is widely used in refrigeration, conditioning, chemical dehumidification, and other related fields. Nowadays, the application of surface has been mature under standard working conditions, more research carried out on its application. However, when conventional coolers are directly high temperature humidity conditions (the higher than 30°C, both ratios 20 g/kg dry air), or with strict dehumidification requirements, expected results often not achieved. Therefore, taking as...
Dual-band GPS occultation receiver is designed to provide highly accurate measurements for atmosphere and ionosphere. The instrument flying on low-Earth orbit (LEO) receives the signals that have crossed ionosphere at varying altitudes. It contains antennas, Radio Frequency Conditioning Units (RFCU) central Electronic Unit. Besides usual real-time navigation, must accurately track a sufficient number of Space Vehicles (SV) Occultation (RO) precise determination (POD), providing...
At Cu/low-K interconnection based BEOL etch technology with double patterning scheme, metal hard mask (MHM) process is the key step to define final physical structure of Cu line. Gap fill and reliability performance are highly related MHM pattern CD profile. During patterning-based process, tri-layers (including organic inorganic nonmetallic materials) HM film (e.g. TiN metalloid material) processes involved. Precondition, by-product stop layers different for each flow in open which could...
