Abstract
The utility model discloses a kind of ACB circuit breaker multiconductor bridge-shaped contact mechanism.It comprises fixed support and upper and lower two groups of contact assemblies, often organize contact assemblies by outer contact with to be positioned at inside outer contact contact composition, extension spring is provided with between two groups of contact assemblies, fixed support is provided with extension spring connecting rod, the two ends of extension spring to be all articulated on extension spring connecting rod and to make to be pressed on the upper and lower end face of extension spring inside the interior contact of each group of contact assemblies, fixed support is also provided with press spring base, in press spring base, is provided with the stage clip of the outer contact outer face that can be pressed in each group of contact assemblies.After adopting above-mentioned structure, when being stored in drawout chassis and being connected with drawout chassis busbar, the interaction force of busbar contact and two groups of contact assemblies is by changing spring relevant parameter, busbar contact contacts completely with the contact of interior contact with outer contact, increase contact area, inside and outside stressed equalization simultaneously, the reliability of contact also improves greatly.
Description
Technical field
The utility model relates to the syndeton that a kind of ACB circuit breaker inserts row and drawout chassis busbar, and specifically a kind of ACB circuit breaker multiconductor bridge-shaped contact mechanism, belongs to equipment for power transmission and distribution technical field.
Background technology
Traditional ACB circuit breaker busbar temperature rise test temperature value is difficult to reach test requirements document always, is in higher state, and its temperature mainly produces with bridge-type contact, bridge-type contact and drawout chassis busbar place in dynamic and static contact, the row of insertion.Good method is not had to improve this situation at present.And traditional bridge-type contact all adopts the arrangement of single group silver strip to contact with busbar, contact area is limited, therefore can produce in bridge-type contact contact position or reserved large amount temperature.
Summary of the invention
The technical problems to be solved in the utility model is to provide the ACB circuit breaker multiconductor bridge-shaped contact mechanism that a kind of contact-making surface is large, contact reliability is good.
In order to solve the problems of the technologies described above, ACB circuit breaker multiconductor bridge-shaped contact mechanism of the present utility model, comprise fixed support and two groups of contact assemblies up and down of arranged relative on fixed support, often organize contact assemblies by outer contact with to be positioned at inside outer contact contact composition, extension spring is provided with between two groups of contact assemblies, fixed support is provided with the extension spring connecting rod between contact and outer contact in each group of contact assemblies, the two ends of extension spring to be all articulated on extension spring connecting rod and to make to be pressed on the upper and lower end face of extension spring inside the interior contact of each group of contact assemblies, fixed support is also provided with press spring base, the stage clip of the outer contact outer face that can be pressed in each group of contact assemblies is provided with in press spring base.
There is outside described contact assemblies the busbar contact that can be inserted between upper and lower two groups of contact assemblies, it is less that the end of described busbar contact is set to nose thickness, the step-like structure that base thickness is larger, described interior contact length is less than the length of outside contact, and the outer end of described interior contact and outer contact is provided with the contact of matching with busbar contact.
After adopting above-mentioned structure, due to the two groups of contact assemblies up and down of arranged relative on fixed support arranged, extension spring between two groups of contact assemblies and setting can be pressed in the stage clip of the outer contact outer face of each group of contact assemblies, arrange when being stored in drawout chassis and being connected with drawout chassis busbar thus, the interaction force of busbar contact and two groups of contact assemblies is by changing spring relevant parameter, busbar contact contacts completely with the contact of interior contact with outer contact, increase contact area, inside and outside stressed equalization simultaneously, the reliability of contact also improves greatly.

Fig. 1 is the structural representation of the utility model ACB circuit breaker multiconductor bridge-shaped contact mechanism;
Fig. 2 is the assembled state cross-sectional view of the utility model and busbar;
Fig. 3 is the assembled state plan structure schematic diagram of the utility model and busbar.
Embodiment
Below in conjunction with the drawings and specific embodiments, ACB circuit breaker multiconductor bridge-shaped contact mechanism of the present utility model is described in further detail.
As shown in the figure, ACB circuit breaker multiconductor bridge-shaped contact mechanism of the present utility model, comprise fixed support 1 and two groups of contact assemblies 2 up and down of arranged relative on fixed support, often organize contact assemblies by outer contact 3 be positioned at contact 4 inside outer contact and form, extension spring 5 is provided with between two groups of contact assemblies 2, fixed support 1 is provided with the extension spring connecting rod 6 between contact and outer contact in each group of contact assemblies, the two ends of extension spring 5 to be all articulated on extension spring connecting rod 6 and to make to be pressed on the upper and lower end face of extension spring 5 inside the interior contact of each group of contact assemblies, fixed support 1 is also provided with press spring base 7, the stage clip 8 of outer contact 3 outer face that can be pressed in each group of contact assemblies is provided with in press spring base 7, there is outside contact assemblies 2 the busbar contact 9 that can be inserted between upper and lower two groups of contact assemblies, it is less that the end of busbar contact 9 is set to nose thickness, the step-like structure 10 that base thickness is larger, interior contact length is less than the length of outside contact, the outer end of interior contact 4 and outer contact 3 is provided with the contact 11 of matching with contact.
During use, after being connected with drawout chassis, entering in drawout chassis and bridge-type contact connection procedure, body busbar first acts on the outer contact 3 in upper and lower two groups of contact assemblies, is acted on by stage clip 8, and the outer contact 3 in these two groups of contact assemblies is first stressed; Continue motion, in upper and lower two groups of contact assemblies interior contact also start stressed by extension spring 5, because contact interior in upper and lower two groups of contact assemblies 2 is different from the gap of busbar with outer contact, thus in realizing, contact is separately connected with outer contact, realizes independent, acting in conjunction.
