Gold-based alloys are widely used in electrical contact environment which requires small contact resistance, and friction pair components consisting of electrical contact has a direct impact on the properties of electrical contact. In this thesis, an experiment of AuNI9 brushes/AuCuAgZn gold sheets in a organization is designed to show the elastic properties of the brush, friction pair wear properties and environmental adaptability of the contact resistance, whose result indicates that the elastic properties of the brushes are stable, alloy sheets mainly produce wear when the brushes and gold sheets are used in matched pair and environmental assessment tests do not significantly increase the degree of wear of the friction pair components in low load condition.

Distributed Energy System

Due to the coupling of different energy systems, optimization of different energy complementarities, and the realization of the highest overall energy utilization rate and environmental friendliness of the energy system, distributed energy system has become an important way to build a clean and low-carbon energy system. However, the complex topological structure of the system and too many coupling devices bring more uncertain factors to the system which the calculation of the interval power flow of distributed energy system becomes the key problem to be solved urgently. Affine power flow calculation is considered as an important solution to solve uncertain steady power flow problems. In this paper, the distributed energy system coupled with cold, heat, and electricity is taken as the research object, the influence of different uncertain factors such as photovoltaic and wind power output is comprehensively considered, and affine algorithm is adopted to calculate the system power flow of the distributed energy system under high and low load conditions. The results show that the system has larger operating space, more stable bus voltage and more flexible pipeline flow under low load condition than under high load condition. The calculation results of the interval power flow of distributed energy systems can provide theoretical basis and data support for the stability analysis and optimal operation of distributed energy systems.
