Abstract
PURPOSE:To constitute a buffer cylinder without any adverse effect upon breaking, power supply and mechanical performances and make a breaker compact by providing the end plate part of the buffer cylinder with a large diameter part larger than cylinder outer diameter, separating the end plate part from the cylinder part and securing the separated part with bolts. CONSTITUTION:A large diameter part larger than a cylinder part 1b is formed on the external surface of an end plate part 1a, and this large diameter part separates the end plate part 1a from the cylinder part 1b. The separated part is fixed with a set bolt 11 for a movable main contactor 9 and another set bolt 12 for the end plate part 1a and the cylinder part 1b. By providing the large diameter part at the external surface of the end plate part 1a for said separation, the electrically live area of the separated part can be maintained and the area of an air intake part 6 can be kept as conventional, thereby giving no adverse effect to breaking performance. Also, the separated part can be properly fastened with the bolts 11 and 12, and therefore the screwed part thereof is free from a mechanical shock at the time of turning on a breaker, thereby enhancing the mechanical reliability of the breaker.
