The bus-bars are usually connected by bolts in the manufacturing of electric power switchgear, but the space is occupied too much by bolts to get adequate electrical gap, so it not only makes the design of structure difficult due to the limit of compact switchgear construction, but also the tip discharge is produced potentially to destroy the air insulation level. To solve this problem, a new connection technology for bus-bar was proposed to replace screw connection including riveting without pin and riveting with pin, and the riveting principle and forming process were researched. Meanwhile, the mechanics simulation was conducted by software ANASYS Workbench to check the consistency. Then, the effects of vibration, temperature rising and resistance were tested after connection, and its feasibility was verified by comparing with the traditional screw connection process. In addition, two finite element analysis models of electric field in the connection scope of bus-bars were set up to obtain the distribution characteristic and the concentrated area of electric field, which further showed its value of riveting. Finally, the advantages and application range of riveting technology were summarized, which provided more technical proposals for product design and process improvement.
