The Principle Of Pressure Self-compensation Of High-voltage Disconnector Contact Blade
Publish Time: Author: Site Editor Visit: 8
One end of the contact blade is mounted on the stationary contact hv isolator switch via a pin. The other end of the contact blade is detachably connected to the stationary contact high voltage electrical isolator. Contact pressure is maintained by contact springs at both ends. When a short-circuit current flows, the attractive force between the two slotted contact blades is strengthened. This also increases contact pressure at the contact point, thereby improving the dynamic thermal stability of the contact isolator high voltage.
