Research on Intelligent Replacement Device for ± 800kV Converter Network Side Bushing

± 800kV converter network side bushing installation process, bushing root and tie rod base connection for the interference fit, if directly inserted, will lead to damage to the outlet device. In order to safely and reliably realize the bushing installation, the operation and maintenance personnel designed a converter network side bushing intelligent replacement device, this device ensures that the bushing downward and the tie rod rising speed, displacement is consistent, the outlet device is in a static state, not affected by the external force, to realize a safe and reliable bushing installation operation.
