Vertical Structure And Control Mechanism Of Vertical Fuse Disconnector

The vertical fuse switch disconnector adopts an up-and-down rotating contact design and is typically used in power distribution systems with voltage levels of 35kV and below. This structural design, while maintaining a visible fracture surface, is equipped with a mechanical operating mechanism and a position indicator. The operating handle drives the contacts to open and close via a transmission device, and the mechanical position indicator can intuitively display the current status of nhrt40 vertical fuse switch disconnector, providing physical feedback conditions for basic control.

When the fuse trips, the melting of the internal molten metal triggers the spring mechanism of the fusible element, pushing the push rod to extend and change the color of the indicator flag from green to red. This mechanical linkage mechanism provides maintenance personnel with a direct means of fault location, allowing them to determine the fuse status without opening the cabinet door.
