Abstract :

Space Solar Power Station (SSPS) will operate in geosynchronous orbit. Its operating environment is rather complicated, including space plasma, energetic particles radiation, extreme temperature, and cosmic rays. To reduce power loss, SSPS has to apply high-voltage (HV) power generation and transmission technique. Deep dielectric charging will be a major problem in the design of insulation structure in SSPS. In this paper, the hopping conductivity of polyimide was studied. Hopping distance and hopping barrier height were obtained from surface potential decay analysis. Second, a deep dielectric charging model of polyimide under FLUMIC spectrum electron irradiation was established, in which the hopping conductivity parameters were applied. The effects of electron flux enhancement and operating voltage on the charging characteristics were discussed in four cases, i.e., A) suspended-HV; B) HV-suspended; C) grounded-HV; and D) HV-grounded. When the electron flux enhancement increases, the influence on case A is much larger than the other three cases. When the operating voltage increases, the influence on cases A and B is small, whereas the influence on cases C and D increases fast. Thus, when designing the SSPS, the effect of operating voltage and electron flux enhancement on the insulation system must be carefully considered.

Abstract :

© 2018 Elsevier Ltd High-k polymer nanocomposites have received increased research interest by virtue of integrating high dielectric constant nanofiller with high breakdown strength, flexibility, and ease of processing of a matrix. With outstanding anisotropy, high-aspect-ratio nanofillers have proved to be much more efficient enhancers of the dielectric properties of nanocomposites when compared with traditional zero-dimensional (0D) fillers, leading to many dielectric and energy storage applications. This review summarizes the latest research on one-dimensional (1D) and quasi-1D fillers based high-k polymer nanocomposites with the focus on the superiority of 1D or quasi-1D high-k fillers in enhancing the dielectric properties and energy storage capability of polymer nanocomposites. Dielectric anisotropy, which plays a critical role in determining the dielectric properties and energy storage capability of polymer nanocomposites, was highlighted and the experimental methodologies for achieving anisotropic dielectric polymer nanocomposites were reviewed. The fundamental electrical parameters, such as dielectric constant, dielectric nonlinearity, dielectric loss and electrical conduction, and breakdown strength of dielectric polymer composites, are also discussed. Given the recent progress, guidelines for the future development of high-k polymer nanocomposites with dielectric and energy storage applications were proposed.

Abstract&Keyword Cite

Abstract :

A comparative study of biaxial-orientated polypropylene (BOPP) films extracted from one failed HVDC filter capacitor (serving for 10 years) and one fresh capacitor (spare capacitor from the same batch) is reported in this paper. Experimental results show that the 10-year online operation does not bring about molecular changes; however, molecule reorganization and recrystallization was detected using differential scanning calorimetry and dynamic mechanical analysis tests. Electrical measurements including dielectric spectra, DC conductivity measurement, DC breakdown strength and were also performed. The experimental results show that the aging process causes an increase in dielectric constant, dissipation factor, DC conductivity, and the DC breakdown strength. Thermal stimulated current measurements indicate that traps were introduced by aging and are responsible for such abnormal changes. The nano-cavitivies generated by molecule reorganization could possibly act as charge traps. Therefore, homo-charges can accumulate in the vicinity of the electrodes, leading to the degradation of long-term withstand strength but an enhancement of short-term breakdown strength.

Abstract :

DC power transmission has become more and more important in power grid construction, and the HVDC cable is one of the most important power devices. However, due to long-time monopoly by foreign firms, China has no enough ability in mass production of stable and reliable HVDC cable insulating materials and shielding materials at present, thus it is urgently needed to develop new cable materials with independent intellectual property rights in our country. From the aspect of technical requirements, we review the research path and future development, research progress and path analysis of HVDC cable materials. Firstly, we discuss the technical requirements including dielectric strength, electric field distribution, and space charge transport. Then, we analyze the present situation, advantages and disadvantages, trap characteristics, and the development direction of cable materials including high purity cable materials, nanocomposite cable materials, blended composite cable materials, grafting cable materials, and shielding materials. Finally, we forecast the future development. The co-relationship between DC insulation characteristics is established using the charge trap theory. The effect of charge trap behavior on DC insulation characteristics is obtained. The trap characteristics and adjusting methods for various paths are summarized. This research can provide a theoretical support for the development of new DC cable materials. © 2018, High Voltage Engineering Editorial Department of CEPRI. All right reserved.

Abstract :

© 2018 Chin. Soc. for Elec. Eng. Nano-doping has a great influence on electrical properties of polymeric dielectrics. Taking pure polyimide 100HN and nano-doping polyimide 100CR from DuPont as research materials, experiments on high-field conductance, surface potential decay (SPD), DC breakdown and corona-resistance were carried out. The experimental results show that the DC breakdown strength of 100CR decreases by 6.4% compared with 100HN, whilst its corona-resistance time increases by 400%, indicating that the nanoparticles could play different mechanisms in two performances. The trap parameters extracted from SPD results indicate that the deep trap energy and density for 100CR are both reduced. The high-field conductance results indicate that conductivity and carrier mobility are both increased for 100CR. The eroded surface morphology after corona by scanning electron microscope show groove channel of 100HN and layered rings with different erosion degrees of 100CR, and the eroded area of 100CR is enlarged. It is concluded that the nanofillers affect the conductance characteristics by changing the trap characteristics, and finally affect the DC breakdown performance. For the corona-resistant mechanism, a synergistic effect of surface collision scattering and charge dissipation is proposed to interpret the layered rings and better corona-resistance performance of nanocomposite.

Abstract :

In the case of silicone rubber, the space charge measurement is confronted with difficulty due to the elasticity of the material. Moreover, it has been found that the space charge presents critical behaviors with respect to the hard material. This work focuses on the positive space charge characteristics of silicone rubber, and try to further understand the positive charge dynamics in silicone rubber material. The space charge profiles were measured by a typical pulsed electro-acoustic (PEA) system under room temperature. A critical positive charge injection and positive charge packet occur in the sample with a low injection field. Negative charge injection also occurs,and the negative homo charge accumulation locates near the electrode. The positive charge packet indicated an enhancement by the field and migrated faster under the high field. Non-uniform distribution of traps and deep hole traps contribute to the positive space charge dynamics in silicone rubber sample. © 2018 IEEE.

Comparison of Degradation Mechanisms and Aging Behaviors of Palm Oil and Mineral Oil during Thermal Aging EI

Abstract&Keyword Cite

Abstract :

As a potential alternative to mineral oil used in transformer, palm oil is an eco-friendly choice while its aging behavior and internal aging mechanism are still unclear. Since the failure in transformer oil-paper insulation is mainly caused by heat, with the purpose of better understanding the similarities and differences of palm oil compared with mineral oil during transformer operation, oil-papers respectively made from these two oils were thermally aged for different duration and then experimentally analyzed. Through the analysis of experimental results, the following conclusions were drawn. Quite different aging mechanisms were revealed for each oil-paper insulation material. That means mineral oil had been degraded by scission of main chains followed with oxidation, whereas palm oil had been degraded by scission of ester bonds followed with loss of terminal carbonyl. The different degradation mechanisms further lead to different changes in dielectric properties during thermal aging. The electron transition energy of mineral oil is more pronounced with the increase of aging degree. Besides, palm oil has a shorter wetting time in paper, and the local damage can be repaired more easily after partial discharge. On the contrary, longer wetting time of mineral oil in paper relates to easily damaged for mineral oil-paper insulation in partial discharge. This work clearly shows that palm oil should be a good substitute for traditional mineral oil not only is it eco-friendly, but also possesses even better performance to some certain extent. © 2018 IEEE.

Abstract :

Transformer life management has gained remarkable recognition due to its crucial role for safe operation of the power grid. Since transformer life is dominated by insulating state of its oil-paper insulation, the DP value has been traditionally regarded as the primary indicator. However, the DP sampling procedure is destructible and inconvenient. In this paper, we present an effective principal component regression method to assess the insulating state of oil-paper through indirectly estimating the degree of polymerization based on the aging characteristic parameter in oil. Thermal aging experiments were firstly conducted on palm oil and mineral oil impregnated paper, respectively. After aging experiments, aging characteristic parameters of oil were tested, including moisture, acidity, 2-furan, surface tension, dissolved gas-in-oil analysis, methanol, and ethanol. Principal component regression method was then performed to find the principal component and build a relationship between the degree of polymerization and the aging characteristic parameters of oil. After computation, the estimation of degree of polymerization value can be obtained with a high goodness of fitting, which is 0.92 and 0.78 for mineral oil and palm oil impregnated paper respectively. The estimation could be improved by data processing. © 2018 IEEE.

Effects of Hygrothermal Ageing on Breakdown Performance of Polyesterimide Nanocomposites EI

Abstract&Keyword Cite

Abstract :

Polyesterimide and its nanocomposites are widely applied in motors and generators. However, the electrical properties of them deteriorated under the hygrothermal environment, which is a critical problem for safe operation of motors and generators in power systems. Therefore, it is urgent to study the mechanism of electrical properties during hygrothermal ageing. In this paper, neat polyesterimide and polyesterimide nanocomposites were prepared. The specimens were exposed in an oven with 100% relative humidity and 80°C for two weeks. The changes of specimen mass were measured to acquire moisture absorption. The breakdown experiment and the thermally stimulated current experiment were conducted. It is found that the trap level decreases after hygrothermal ageing process, which leads to the promoted carrier migration and the deceased breakdown strength. In addition, as the ageing time increases, the reduction proportion of breakdown strength of polyesterimide nanocomposites is smaller than that of neat polyesterimide. It is inferred that the interaction zone induced by nanoparticles, on one hand, increases the deep trap level. On the other hand, the bonding between nanoparticles and the matrix is enhanced by the surface treatment on nanoparticles, resulting in improved property stability of nanocomposites in the hygrothermal ageing. © 2018 IEEE.
