Room temperature vulcanized (RTV) silicone rubber is extensively used in power system due to its hydrophobicity and transfer ability. Temperature has been proven markedly affect the performance of rubbers. This research investigated degradation RTV under cycling treatment. Hydrophobicity ability, hardness, functional groups, microscopic appearance, thermal stability were analyzed using static contact angle method, a Shore A durometer, Fourier transform infrared spectroscopy (FTIR), scanning...
Photo-induced conductivity modulation of stimuli-responsive materials is great importance from the viewpoint fundamental research and technology. In this work, 5 new kinds azobenzene-based photo-responsive ionic liquids were synthesized characterized, UV/vis light their was investigated in an aqueous solution. The factors affecting fluids, such as photo-isomerization efficiency, photo-regulation aggregation, concentration chemical structure liquids, examined systematically. It found that...
In order to study the difference in performance of room temperature vulcanized (RTV) silicone rubber vulcanization environment with different and humidity, static contact angle method, FTIR TG is utilized depict properties hydrophobicity, transfer functional groups thermal stability RTV rubber. It found that conditions have effects on characteristics rubber, which shows hydrophobicity changes little but a slight increase humidity. Temperature humidity obvious ability better when 5°C or 95%....
PEDOT has been widely used in advanced electronics, and one of the keys to determine performance is hole mobility.
Humidity is a critical factor in atmospheric corona discharge. Fluid dynamics models have become common method to explore the detailed discharge characteristics humid air. However, require specification of some key parameters, such as electron swarm parameters and Townsend coefficients, which strongly depend on energy distribution function (EEDF). In this paper, EEDFs dry air water vapor are compared by solving Boltzmann equation using classical two-term approximation. Moreover, drift...
Atmospheric corona discharge plasmas are the most common diversely occurrence in electric power system. In this paper, four elementary processes occurred taken into account, including elastic collision, excitation, attachment, and ionization. As one of important parameters characteristics analysis, effective Townsend ionization coefficient is completely calculated by Boltzmann equation under consideration humidity. This paper also derives electron energy distribution function (EEDF) water...
Concerns over the operation safety of power transformers have triggered an application room temperature vulcanized (RTV) silicone rubber on transformer bushings. However, oil may cause a severe deterioration in performance RTV coatings due to leakage. Little attention has been paid degradation oil. This paper presents experimental investigation explore An immersion experiment is performed. Mass, hardness and hydrophobicity are analyzed research macro properties rubbers. FTIR, XPS SEM...
Room temperature vulcanized (RTV) silicone rubber is widely used in external insulation of electrical equipment for antipollution flashover because it has many merits such as superior hydrophobicity and migration hydrophobicity, but also weakness poor aging performance. The study on the failure criterion RTV always a concern since there been no generally accepted method its criterion. Corona an important effect recovery performance rubber. In this paper, tests were conducted to reveal corona...
Room temperature vulcanized (RTV) silicone rubber is widely used to prevent pollution flashover with its excellent hydrophobicity and transfer.However, RTV coatings are at the risk of deterioration failure in heavily polluted operating environment.In this paper, coated insulators different suspension heights coal ash areas were sampled.Pollution degree, composition aging degree tested.The result shows that insoluble contains Al(OH) 3 filler precipitated from coating, which indicates...
The composition of metallurgical contamination is rather special, which has a great influence on the accumulation and flashover characteristics insulators. In this study, 500 kV AC line insulators in industry area central China were sampled. ion composition, element micromorphology particle size distribution at high low end insulator string tested, respectively. equivalent salt deposit density (ESDD) non‐soluble (NSDD) high‐voltage end, low‐voltage middle segment three‐phase strings tested....
The performance of room temperature vulcanized (RTV) silicone rubber under various operation conditions is always a hot point in the study external insulation. influences transformer oil on RTV have been little investigated, which are crucial issues for covering bushing because potential leakage problems. In present work, immersion experiment applied to explore rubber. Samples immersed into at 70 °C and 110 4, 8, 24, 72, 168 336hrs, respectively. They analyzed by contact angle measurement...
The metallurgical industry in China has developed rapidly, which caused an increasing amount of exhausted gas emission. After a long period operation, layer contamination is deposited on the surface insulators near metal work, may have effect distribution electric field insulator. chemical test indicates that contains particles Fe3O4 with strong conductivity, become suspended potential conductor. In this paper, influence thickness and diameter, arrangement conductive are discussed by...
An emergency frequency control strategy using demand response based on deep reinforcement learning is proposed. According to the system before and after fault, used predict amount of load shedding by trained prediction model. Firstly, genetic algorithm optimize multi-objective function optimal load-shedding fault target power grid. Q-learning establish action mapping relationship between response, so as obtain sample data. After training data convolutional neural network (CNN), a model...
