Seismic Optimization Study of Substation Bus-Bar Connecting Circuit

Bus-bar is an important power transmission channel in substation. To improve the safety performance of bus under the action of earthquake, the finite element simulation calculation is carried out for the bus-bar circuit in UHV substation. And this study analyzes the influence of structural design parameters such as tube bus layout and bracket span on earthquake response of pillar insulator in the circuit. The results show that the seismic performance of the bus-bar connecting circuit can be optimized by using independent tubular bus layout for each span, increasing insulator support and reducing the span of single tubular bus.
