Medium voltage circuit breaker |
摘要 |
A Medium Voltage circuit breaker which comprises a pole assembly having, for each phase, a first fixed contact and a second movable contact reciprocally couplable/uncouplable between an open and close position. The circuit breaker further comprises an actuator to actuate the opening and closing operation of said circuit breaker, and a kinematic chain operatively connecting said actuator to said movable contact. The kinematic chain comprises a sliding element operatively connected to said actuator, said sliding element having a first sliding surface operatively coupled to said movable contact and being movable between a first, open, position and a second, closed, position. |

1. A medium voltage circuit breaker comprising a pole assembly having, for each phase, a first fixed contact and a second movable contact reciprocally couplable/uncouplable between an open and close position, an actuator to actuate an opening and closing operation of said circuit breaker, and a kinematic chain operatively connecting said actuator to said movable contact, said kinematic chain comprising a sliding element operatively connected to said actuator and which is linearly movable by said actuator, said sliding element having a first sliding surface operatively coupled to said movable contact and a second sliding surface, which is opposite to said first sliding surface;
wherein said sliding element moves without rotating around the connection point with said actuator; wherein said first sliding surface is coupled to a second roller that is connected to said movable contact and said second sliding surface is operatively coupled to a first roller that is mounted on a fixed part of the circuit breaker; wherein said first sliding element is movable between an open position and closed position; wherein a profile of said first sliding surface is not flat and is shaped so that the profile of said first sliding surface has at least a first and a second segment having different slopes; wherein the profile of said second sliding surface is flat and straight for the entire length of said second sliding surface; wherein said second roller and said movable contact are linearly movable along a same second direction of movement that is perpendicular to the first direction of movement of said sliding element; wherein said first roller is in a fixed position with respect to said sliding element to support said sliding element. |
