The purpose of this study is to suppress the temperature rise of high voltage wall bushing metal plate.
First, the authors built a model of a traditional metal plate and got the magnetic field intensity distribution by FEA tools. Optimized according to the magnetic field intensity distribution, the authors slot the traditional metal plate and embed permanent magnets in the slot. Finally, the authors got the temperature distribution diagrams of the above three cases at different current levels by FEA tools.
Slotted metal plate is beneficial to suppress magnetic induction intensity, but the improvement of the magnetic induction intensity uniformity is not obvious. The method of embedding a permanent magnet in a slotted metal plate can optimize the magnitude and uniformity of the magnetic induction intensity in the metal plate. The larger the current passing through the metal plate, the better the temperature suppression effect of the slotted metal plate and the slotted metal plate embedded in the permanent magnet.
The effect of structural factors, slotting plate and setting permanent magnets on slots on the temperature of supporting plate is studied. The paper proposes two methods, slotting metal panels and embedding permanent magnet metal panels, to solve the problems of eddy current loss and high calorific value of the panel, which is of great significance to the safety of the grid equipment.
The purpose of this study is to review the development of the socially sustainable supply chain management field.
The 112 most cited papers in the field until 2017 are analysed using a state-of-the-art structured literature review model borrowed from the accounting field.
This study highlights the increasing number of publications across the years, the diversity of journals and the type of authors addressing the topic. It reveals that qualitative studies focused on large companies in the garment, food and electronics sectors and on private regulations capture most of the attention, with Asia, Europe and North America being the most scrutinised locations. Drivers and barriers for socially sustainable supply chain management are summarised, clustered and confronted. This study also evaluates how the sustainability and corporate social responsibility concepts are used in the above field and analyses the existing definitions of social sustainability.
This study incites researchers to broaden their studies to diverse sectors and locations, addressing different levels of supply chains with quantitative techniques and clearer conceptual foundations.
This study incites practitioners to further contribute to this scholars-dominated research field, offering their practical insights and perspectives.
This study offers original insights and critiques of the literature, highlighting its gaps and proposing new research avenues for the future.
