Definitions
- the present invention relates to a vacuum switch tube driving mechanism for opening and closing a vacuum switch tube, and a vacuum circuit breaker using the same.
- the conventional vacuum switch tube drive mechanism is connected to the movable contact drive rod of the vacuum switch tube fixed on the fixed contact side, and drives the movable contact drive rod in the axial direction according to the operation of the operation mechanism.
- the operating mechanism is provided on the frame and is pin-coupled to one end of a link mechanism composed of a link, rotates the link, and applies a driving force to a movable contact drive rod pivotally attached to the other end of the link mechanism. It is configured to:
- the connecting end of the movable contact drive rod makes a rotational movement about the pivot axis of the link during the shutoff or closing operation, and the movable contact drive rod has an axis.
- a forced displacement in a direction (radial direction) almost perpendicular to the center, that is, a swing displacement is given.
- a distortion occurs in the vacuum switch tube, which causes a problem that the durability of the vacuum switch tube is reduced.
- the present invention has been made in order to solve the above-described problems, and is intended to prevent a radial force from being applied to the movable contact drive rod of the vacuum switch tube in the process of shutting or closing operation. It is an object of the present invention to provide a vacuum switch tube drive mechanism which does not impair the durability of the vacuum switch tube and a vacuum circuit breaker using the same. Disclosure of the invention

Further, a vacuum circuit breaker using such a drive mechanism is also disclosed.
- FIG. 1 is a schematic side view showing an embodiment of the vacuum circuit breaker of the present invention.
- FIG. 2 is a schematic front sectional view taken along line 2_2 in FIG. BEST MODE FOR CARRYING OUT THE INVENTION
- FIGS. 1 and 2 show one embodiment of a vacuum circuit breaker using a vacuum switch tube driving mechanism of the present invention.
- the vacuum circuit breaker includes a vacuum switch tube 1.
- a frame 2 is supported, and a drive mechanism 3 supported by the frame 2 for opening and closing the vacuum switch tube 1 is provided.
- the vacuum switch tube 1 itself may be a known one, and is connected to the vacuum vessel 4, the fixed contact 5 and the movable contact 6 provided in the vacuum vessel 4, and the movable contact 6 to open and close it. And a movable contact drive rod 7 for driving the fixed contact 5 and a movable contact 6 connected to the fixed contact 5 and the movable contact 6, respectively, to form a current path.
- the frame 2 includes, for example, a substrate member 10 that can be a part of the structure of the switchgear, and a first insulating support 1 that is fixed to the substrate 10 and insulates and supports the fixed terminal 8 of the vacuum switch tube 1. 1 and a second insulating support member 12 fixed to the substrate member 10 and insulatingly supporting the movable terminal 9 of the vacuum switch tube 1.
- the second insulating support includes a hollow, substantially box-shaped insulating housing 13 formed of a suitable insulating resin material such as epoxy resin, and the above-described drive mechanism 3 is provided in the insulating housing 13. It is stored and supported.
- the drive mechanism 3 for opening and closing the vacuum switch pipe includes a follower 15 which is a roller rotatably provided via a pin 14 at the tip of a movable contact drive rod 7 of the vacuum switch pipe 1. I have.
- the follower 15 is inserted into a cylindrical guide 16 having an oval cross section provided in the insulating housing 13, and its movement is in the drive direction (vertical direction in the figure) of the movable contact drive rod 7. Guided in parallel by the guides 17 It is restricted not to move in the direction.
- the first link 18 is also pivotally connected to the pin 14 supporting the follower 15 on the movable contact drive rod 7, and the other end of the first link 18 is connected to the second link by the pin 19.
- the other end of the second link 20 is pivotally connected to the insulating housing 13 of the frame 2 by a pin 21.
- the second link 20 has a leg 22 that is opened in a substantially V-shape in the illustrated example.
- One leg of the two legs opened in a V-shape is a second link 20, the tip of which is pivotally connected to the first link by a pin 19, and a connecting portion of the two legs ( The lower side in the figure, the other end of the second link 20) is pivotally connected to the insulating housing 13 by a pin 21.
- an operating lever 24 is pivotally attached to the tip of a leg 22 extending integrally from the second link 20 in a V-shape by a pin 23.
- the other end of the operating lever 24 extends through the punch plate member 10 of the frame 2 and is not shown, but can be connected to the operating mechanism of the switchgear by a connecting means such as a suitable pin. .
- the first link 18 and the second link 20 of the drive mechanism 3 constitute a bending and stretching link mechanism 25 that performs a bending and stretching movement using the pin 19 as a knee joint pin.
- One end of such a bending / extending link mechanism 25 is pivotally connected to a follower 15 guided by a guide 6 so that only one end moves linearly, and the other end is insulated by a pin 21. It is pivoted so that it cannot move to 13. Therefore, if a force is applied to at least one of the first link 18, the second link 20, and the pin 19, which constitute the bending / extending link mechanism 25, the bending / extending link mechanism 25 performs a bending / extending motion, The pin 14 and thus the movable contact drive rod 7 can be driven vertically in the figure.
- a pivot point for pivoting the link can be provided on any component of the bending / extending link mechanism 25.
- the pivot point or pin 22 is provided at the distal end of the leg 22 extending integrally from the second link 20, and the position of the pin on the second link 20 or the pivot Regarding the contact point, the pivot point 23 with the operating lever 24, the pivot point 14 with the first link 18 and the pivot point 21 with the insulating housing 13 form the vertex of the triangle. Is located in the position.
- the insulating housing 12 of the frame 2 accommodates and supports the drive mechanism 3, and more specifically, the movable contact drive rod 7 of the vacuum switch tube 1 and the follower 15 as a roller.
- the first link 18 and the second link 20 constituting the bending / extending link mechanism 25 are surrounded.
- the movable contact drive rod 7 is guided by the guide 16 to drive in the axial direction, that is, to drive the movable contact. Because it moves only in a direction parallel to the direction, no radial force is applied to the movable contact drive rod of the vacuum switch tube during the shutoff operation, and the durability of the vacuum switch tube is not impaired.
