Development and Application of the "4S Electrical Testing Suitcase "

A high-voltage test combination tool for multiple scenarios of power transmission and transformation has been designed and developed to meet the specific needs of the power production site. The design scheme was formulated by addressing practical problems associated with traditional operation methods, such as inflexible layout, inconvenient use, unreliable fixation, and incomplete integration of accessories. The brainstorming and inductive summary methods were employed to propose the design scheme. The finished product was tested on the work site, resulting in improved safety measures for the staff, including flexible arrangement of safety warning belts and test pressure lines.
