Research on Vibration Measurement Technology and Safety Evaluation Method of Outdoor Isolating Switch

In view of the obvious wind-induced vibration of the pillar switchgear in the windy area, which makes the switch opening and closing operation difficult, and brings security risks and other problems. This paper through the research of non-contact vibration measurement technology, long-distance, non-contact vibration measurement has been realized, which provides vibration measurement technology, means and tools for the operation and maintenance management department. Combined with the vibration characteristics of each position of the pillar switchgear obtained from the vibration measurement, the paper established a simplified model, which is used to analyze its amplitude offset and force characteristics. The obtained results are carried out evaluation analysis with the mechanical properties and limits of each component, and giving warning prompts for parts that exceed the range, and risk prompts are also given for components with large vibration offsets, and give suggestions such as installation of damping devices.
