[0027] like figure 1 , image 3 As shown, the present invention includes a static contact mechanism 1 and a movable contact mechanism 2 that are used together, a movable contact base 3 for installing the movable contact mechanism 2, and an insulation for driving the movable contact mechanism 2 to perform up and down opening and closing actions. Pull rod 4, the movable contact mechanism 2 is coaxially installed in the cylinder 1 and driven by the cylinder 1 to open and close. The static contact mechanism 1, the moving contact mechanism 2 and the moving contact base 3 are installed in the arc extinguishing porcelain sleeve 10 from top to bottom and all three are coaxially arranged. The inner diameter of the circuit breaker cylinder is 40-50% smaller, and the cylinder 1 is a pressure cylinder with remaining volume inside when the movable contact mechanism 2 performs the opening action. The cylinder block of the cylinder 1 is a formed cylinder block made of copper-chromium alloy...
