具体实施方式 Detailed ways

如图1所示，真空断路器的弹簧操动机构设置在绝缘拉杆1的侧面，弹簧操动机构包括操动轴9和操动拐臂11，操动拐臂11固定在操动轴9上，操动拐臂11的一端铰接有分闸弹簧12，分闸弹簧12的另一端固定在支座14上，分闸弹簧12为垂直设置；操动拐臂11的另一端铰接有触头弹簧7，触头弹簧7的另一端铰接有从动拐臂5，从动拐臂5可以围绕销轴4转动，在从动拐臂5的另一端通过销轴3铰接有绝缘拉杆1，销轴3被限制在底座2上的长槽孔内，使销轴3只能做上下运动。As shown in Figure 1, the spring operating mechanism of the vacuum circuit breaker is arranged on the side of the insulating pull rod 1. The spring operating mechanism includes an operating shaft 9 and an operating arm 11, and the operating arm 11 is fixed on the operating shaft 9. , one end of the actuating crank arm 11 is hinged with a opening spring 12, the other end of the opening spring 12 is fixed on the support 14, and the opening spring 12 is vertically arranged; the other end of the actuating crank arm 11 is hinged with a contact spring 7. The other end of the contact spring 7 is hinged with the driven crank arm 5, which can rotate around the pin shaft 4, and the insulating pull rod 1 is hinged at the other end of the driven crank arm 5 through the pin shaft 3, and the pin shaft 3 is limited in the slotted hole on the base 2, so that pin shaft 3 can only move up and down.

本实用新型在工作时，合闸时，操动轴9带动操动拐臂11顺时针转动，使分闸弹簧12压缩储能，同时操动拐臂11推动触头弹簧7使其被压缩并带动从动拐臂5逆时针转动，从动拐臂5推动绝缘拉杆1向上运动，使绝缘拉杆1上部连接的动触头与静触头接触，操动轴9由外部的限位机构限位而不能转动，完成合闸操作。分闸时，已被压缩储能的分闸弹簧12被释放，带动拐臂11逆时针旋转，拐臂11另一端通过连接触头弹簧7将运动传到拐臂5，使其顺时针转动，带动绝缘拉杆1向下运动，使动触头与静触头分离实现分闸。When the utility model is working and closing, the operating shaft 9 drives the operating arm 11 to rotate clockwise, so that the opening spring 12 is compressed to store energy, and at the same time, the operating arm 11 pushes the contact spring 7 to be compressed and Drive the driven crank arm 5 to rotate counterclockwise, and the driven crank arm 5 pushes the insulating rod 1 to move upward, so that the movable contact connected to the upper part of the insulating rod 1 contacts the static contact, and the operating shaft 9 is limited by the external limit mechanism Instead of turning, complete the closing operation. When opening the brake, the opening spring 12 that has been compressed and stored energy is released, driving the crank arm 11 to rotate counterclockwise, and the other end of the crank arm 11 transmits the motion to the crank arm 5 by connecting the contact spring 7 to make it rotate clockwise. Drive the insulating pull rod 1 to move downward, so that the moving contact is separated from the static contact to realize opening.
