Instructions For Maintaining The Operating Mechanism Of The High-voltage Disconnect Switch At A Height Of Approximately 1m.

According to the installation instructions for hv isolator switch, the distance from the fulcrum of the operating mechanism handle to the ground is typically 1–1.3m.

This height allows operators to perform opening and closing actions using the manual or electric operating mechanism while standing on the ground, without the need for additional steps or lifting devices. The operating mechanism converts the operating input into spindle rotation via a transmission mechanism such as a lever, crank arm, or connecting rod, driving the isolating switch to open or close.

A height of approximately 1m facilitates the arrangement of the operating mechanism and connecting structures in compact cabinet environments, while simultaneously satisfying operational flexibility and human-machine interface convenience. Once the height is configured, components such as the operating mechanism, insulators, and base can be rationally laid out according to standard structures.

Setting the operating mechanism at this typical height balances multiple requirements, including equipment performance, construction convenience, and human-machine interface convenience. The overall design, cabinet dimensions, and installation requirements of high voltage electrical isolator are matched with this set height.
