A Wind Turbine Safety Chain Tester and a Speed Overspeed Monitoring System

Abstract

This application provides a safety chain tester for wind turbines and a speed overspeed monitoring system, which includes a tester body equipped with a power interface, a touch screen display, a first speed interface, a second speed interface, and a power switch. Both the first speed interface and the second speed interface are used to connect to the speed overspeed monitoring system. The touch screen display is equipped with a gear ratio setting window, a first speed setting window, a pre-change second speed ratio setting window, a post-change second speed ratio setting window, a start button, and a synchronization button. The functional components, located within the touch screen display, are used to set operating parameters. Due to the inclusion of the gear ratio setting window, the first speed setting window, the pre-change second speed ratio setting window, and the post-change second speed ratio setting window on the tester, it is possible to effectively test the speed overspeed monitoring component of the wind turbine safety chain system when testing various parts of the system.
