摘　　要：GIS设备是输配电系统的重要构成部分,其市场容量与电力事业的发展紧密相连,因此对于GIS设备及其连接模块的抗震也相应提出了更高的要求。本文以300 kV复合套管为研究目标,对套管、钢架支撑进行三维建模和有限元分析。采用静态系数法来模拟复合套管和钢架支撑在0.5 g峰值加速度下的应力及应变响应,并进一步通过公式和第四强度理论来计算螺栓连接的受力;在确认螺栓连接处应力已超过材料的许用极限后,进行了设计改进和强度校核。最后,在试验室按照IEEE-693标准顺利通过了完整的0.5g地震试验,再次验证了复合套管设计和结构的可靠性;同时也提升了产品在市场上的竞争力和影响力。GIS is one important component of power transmission and distribution system;its market capability is closely connected to the development of electricity utility, therefore, higher requirements on seismic level for GIS and its connection modules are put forward. In this paper, 300 kV composite bushing is set as research subject. 3D modeling and finite element analysis are carried out on composite bushing & steel support. Static coefficient method is used to simulate the stress and strain response of the composite bushing and steel support under 0.5 g peak acceleration. Furthermore, the stress of bolt connection is calculated by the formula and the fourth strength theory. Design improvements and strength checks have been made after the stress exceeding the permissible limit of materials. Finally, complete 0.5 g seismic test was conducted successfully in the laboratory according to IEEE-693 standard, which further verifies the reliability of design & structure of composite bushing. Meanwhile, it also improves product competitiveness and influence in the market.
