Problem Of Tooth Burst On Sector Gear Of High Voltage Disconnector

The issue of tooth bursting on the high voltage isolator switch sector gears has recently attracted industry attention. With the continued expansion of power grid construction and the increasing load on equipment, some hv isolator operators have reported experiencing poor gear meshing, abnormal torque, and partial tooth breakage during long-term operation. To address this, several hv isolator switch manufacturers are actively optimizing their designs by adjusting the tooth profile parameters of the high voltage electrical isolator sector gears, using high-strength alloys, and improving surface hardening processes to enhance overall durability and fatigue resistance.
