What Should Be Considered When Arranging The Operating Mechanism Of A High-voltage Disconnect Switch?

When arranging the high voltage electrical isolator mechanism, the position of the operating mechanism should form a reasonable transmission interlock with the main circuit, grounding switch, and post insulator. The operating shaft, connecting rod, tie rod, and contacts must be concentric, coaxial, and symmetrically arranged to ensure the synchronous mechanical action of the isolator high voltage mechanism and reliable contact engagement.

The mounting base for the high voltage isolator drive mechanism should be selected on a sturdy foundation with low vibration to avoid vibration and misalignment that could lead to linkage failure, contact wear, or mechanism jamming. The connection between the base and the supporting structure should have sufficient rigidity and alignment accuracy.
