摘要:
MOA作为电力系统中限制过电压的主要设备之一,其性能的优劣直接关系到电力设备的安全运行。对MOA的不同运行状况、不同受潮部位进行了试验分析,通过光纤场强测试仪对MOA在不同运行状况下的沿面纵向场强及电位分布特性进行了研究,确定了避雷器在正常及不同受潮部位下沿面纵向场强及电位的分布特性。通过现场试验验证了光纤场强法在MOA带电检测中的有效性,同时也为MOA现场带电检测提供了新的途径。
Abstract:
Zinc oxide arrester is one of the most important equipment in power system, with its performance directly related to the safety and stability of power grid. In this paper,the different operation states and the damp position of MOA were tested and analyzed, and the longitudinal field strength and the potential distribution characteristics of MOA under different operating conditions were studied using the optical fiber field strength tester. The feasibility of the optical fiber field strength method in the MOA live detection has been verified, which provides a new way for the live-test method of MOA.
