This work also experimentally studies the electrical characteristics of the gas medium and the monitored parameters are also used to calibrate the arc model. The amount change of the seven dominant decomposing by-products is analysed as well. The results present that the C4F7N/CO2/O2 ternary gas mixture exhibits a more promising interrupting performance. Increasing the O2 concentration from 5% to 10% has less effects on the arc characteristics, but it could suppress the formation of CO. The arc behaviour of C4F7N/CO2/O2 gas mixture is also improved with increasing the velocity of the moving components. The findings provide important insights into the potential of C4F7N-based gas mixtures as one of the sustainable and effective solutions for high-voltage interrupting applications.","PeriodicalId":48649,"journal":{"name":"High Voltage","volume":"10 1","pages":"228-242"},"PeriodicalIF":4.9,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/hve2.70003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143533999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, the new characteristics that arise from the high penetration of IBRs in power systems are reviewed. In light of these characteristics, current simulation technologies are inadequate and new requirements for the simulation platforms have been proposed. In response, this paper introduces the rapid system prototype (RSP)-based physical simulation platforms, which include the digital simulator, the rapid prototype controller, and the rapid object-controlled prototype. RSP addresses the time-consuming and labour-intensive shortcomings of traditional simulation techniques and meets the rapid evolution needs of the power system with high penetration of IBRs. Compared with existing simulation platforms, RSP is a more suitable platform for the physical simulation of power systems with high penetration of IBRs. Using the modular multilevel converter-based high-voltage direct current as a case study, a novel physical simulation platform for power systems based on RSP is constructed. Experimental results demonstrate that the RSP concept and technology can establish an enterprise-level simulation environment and engineering practice platform. Moreover, it can provide realistic and flexible simulations of various characteristics of power systems with high penetration of IBRs.","PeriodicalId":48649,"journal":{"name":"High Voltage","volume":"10 1","pages":"3-16"},"PeriodicalIF":4.9,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/hve2.12520","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143533409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The formation mechanism of the destructive delamination was then unveiled, identifying excessive residual thermal stress due to an inappropriate sintering temperature as the ringleader. Furthermore, an optimisation methodology of the sintering temperature for the PLD-based nano-Ag layer was proposed, determining an optimal temperature range spanning from 190 to 211°C.

This paper tested the power frequency permittivity and direct current conductivity of aged and damp oil-paper insulation samples at different testing temperatures, and constructed a dynamic dielectric parameter calculation model. Meanwhile, a simulation model was established based on the actual structure of the 252 kV/1250 A bushing which is mainly used for the oil-immersed high-voltage bushings of 110 kV and above. The electric-magnetic-thermal multi-physical fields were used for simulation analysis. The influence of ageing/moisture (different degrees of dampness in the upper and lower regions) on the electric field distribution in the bushing was obtained. During the initial to steady-state process, the electric field distribution at the zero and end shield shows a reversal phenomenon. When the capacitor core has different degrees of dampness in the upper and lower regions, the impedance distribution of the capacitor core is non-uniform. This phenomenon will lead to an increase in the radial electric field gradient at the end shield of the capacitor core, which is prone to the risk of slip-flashing discharge. In summary, this paper adopts the field-induced dynamic parameters method to analyse the changes of multi-physical fields in the bushing. This can provide theoretical guidance for optimising the bushing structure and on-site maintenance.","PeriodicalId":48649,"journal":{"name":"High Voltage","volume":"10 3","pages":"773-784"},"PeriodicalIF":4.9,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/hve2.12521","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144520260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that the discharge channel in the 0.1 mm oil gap forms in 9.50 µs when the streamer and the first shock wave are observed.

With the gap distance increase, all the breakdown voltage, the discharge energy, and the ratio of the mechanical energy to total energy increase, the breakdown current, the acceleration of the container wall, and the velocity of the shock wave decrease.

Then, the calculation model of transient temperature rise was constructed for a 252 kV/3150 A bus, and a temperature rise experimental platform was built to verify the reliability of the proposed calculation model. On this basis, the influence of different factors such as load current, charging pressure, mixing ratio, and structure size on the temperature rise of the bus was further analysed, and it is found that increasing the charging pressure and the mixing ratio of C5F10O could effectively reduce the bus temperature rise but it still could not reach the level of SF6. The main structure size that affects the temperature rise of the bus is the outer diameter of the conductor, which increases by 10.2%, and the temperature rise is the same as that of the original SF6 bus.
