Abstract
The invention discloses a high-voltage switch which comprises a shell, a vacuum arc extinguish mechanism and an operation mechanism, wherein the vacuum arc extinguish mechanism and the operation mechanism are disposed in the shell. The vacuum arc extinguish mechanism comprises three horizontal vacuum arc extinguish chambers and movable pull rods connected with movable contacts in the vacuum arc extinguish chambers. The operation mechanism comprises a spindle, three transmission components and a permanent magnetic driving mechanism with a driving rod. The spindle drives the corresponding movable pull rod to reciprocate through each transmission component to complete switching on and off actions. The spindle is provided with a driving crank which is driven by the driving rod to rotate in a reciprocated manner. The high-voltage switch is compact and reasonable in structure, and using the internal permanent magnetic driving mechanism to substitute a traditional popping operation type driving mechanism effectively reduces the integral size and improves stability and reliability in operation.
