The wind farm-specific isolating switch + fuse combination is an outdoor high-voltage protection appliance with a drop breaking function. It is suitable for wind farms and power stations as an essential product for protection segmentation. It is installed on the high-voltage side of distribution transformers or branch lines of distribution lines for overload and short-circuit protection of transmission lines and power transformers and for breaking and closing rated load currents. It has simple operation and convenient maintenance. Effectively solve trouble-free drops. This product improvement is mainly aimed at factors such as failure-free falls and unstable operation in wind farms. The isolation switch function is improved on the fuse body, and the protection function of the fuse is retained, with the functions of opening short-circuit current and fault current.
