Description

A kind of novel breaker drive mechanism
Technical field
The utility model relates to power switchgear technical field, is specifically related to a kind of novel breaker drive mechanism.
Background technology
In electric power system, power distribution network is an important step, and can user obtain safe and reliable electric energy, and the vacuum ring main unit in power distribution network plays an important role.Along with the lasting propelling that intelligent power network is built, the product quality of user to vacuum ring main unit proposes more higher demands, requires that ring main unit structure is more simple, stricter to the requirement of technical parameter.At present, circuit breaker drive mechanism in vacuum ring main unit as shown in Figure 1, comprise driving shaft 1, support 2, vacuum tube 3 and and be arranged on vacuum tube fixed contact 31 inside vacuum tube 3 and vacuum tube moving contact 32, movable connecting rod 4 and be set in fairlead 5 on movable connecting rod 4, described movable connecting rod 4 one end is connected with vacuum tube moving contact 32, the other end is directly connected with driving shaft 1.This traditional structure in making process, the bounce of breaker vacuum pipe moving contact can not direct effect on the driving shaft, the moment of torsion produced driving shaft is comparatively large, is difficult to the spring suppressing breaker vacuum pipe moving contact.
Summary of the invention
In order to overcome the deficiency of above-mentioned existing equipment, the utility model provides one, and both holding structure was simple, effectively can suppress again the novel breaker drive mechanism of the spring of breaker vacuum moving contact.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of novel breaker drive mechanism, the vacuum tube fixed contact comprising driving shaft, support, vacuum tube and be arranged on inside vacuum tube and vacuum tube moving contact, movable connecting rod and the fairlead be set on movable connecting rod, described movable connecting rod one end is connected with vacuum tube moving contact, it is characterized in that, this drive mechanism also comprises a connecting lever, described connecting lever output is connected with driving shaft, and described connecting lever force side is connected with movable connecting rod, and the flex point of described connecting lever is connected with support.
Further, described connecting lever is in " L " type structure.
Further, described support is " L " type structure, and described movable connecting rod is through support, and the described end points of support another side is connected with the flex point of connecting lever.
Further, bearing pin is adopted to connect when described connecting lever is connected with driving shaft, support and movable connecting rod.
The beneficial effects of the utility model: the utility model one connects the novel breaker drive mechanism of movable connecting rod and driving shaft by " L " type connecting lever, described connecting lever and driving shaft junction are the force side of connecting lever, be the output of connecting lever with the junction of movable connecting rod, movable connecting rod drives breaker vacuum pipe moving contact to move up and down by fairlead; When "on" position, the output of the force side of connecting lever, movable connecting rod and connecting lever is on same straight line, the structural design of " sight alignment formula " can make the bounce effect of breaker vacuum pipe moving contact on the driving shaft like this, hardly moment of torsion is produced to driving shaft, effectively suppress the spring of breaker vacuum pipe moving contact, structure is unification simply, ensures the mechanical property parameter of circuit breaker, very practical.
Accompanying drawing explanation
Fig. 1 is conventional circuit breaker drive mechanism schematic diagram.
Fig. 2 is the structural representation of the utility model preferred embodiment.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
With reference to Fig. 2, a kind of novel breaker drive mechanism, the fairlead 5 comprising driving shaft 1, support 2, vacuum tube 3 and be arranged on vacuum tube fixed contact inside vacuum tube 3 31 and vacuum tube moving contact 32, movable connecting rod 4 and be set on movable connecting rod 4, described movable connecting rod 4 one end is connected with the moving contact 32 of vacuum tube, the other end is connected with driving shaft 1 by one " L " type connecting lever 6, described connecting lever 6 and driving shaft 1 junction are the force side of connecting lever 6, are the output of connecting lever 6 with the junction of movable connecting rod 4; Described support 2 is " L " type structure, and described movable connecting rod 4 is through support 2, and the end points of described support 2 another side is connected with the flex point of connecting lever 6.
In the present embodiment, when described connecting lever 6 is connected with driving shaft 1, support 2 and movable connecting rod 4, adopt bearing pin 7 to connect, other connectors such as bolt also can be adopted to connect.
Concrete making process is: driving shaft 1 rotates counterclockwise, connecting lever 6 is driven to rotate by bearing pin 7, the rotation of connecting lever 6 drives movable connecting rod 4 to move up and down, described movable connecting rod 4 drives breaker vacuum pipe moving contact 32 to do rectilinear motion through fairlead 5, described connecting lever 6 and driving shaft 1 junction are the force side of connecting lever 6, with the output that the junction of movable connecting rod 4 is connecting lever 6, when driving shaft 1 turn to straight down direction time, breaker vacuum pipe 3 just closes a floodgate and puts in place, the now force side of connecting lever 6, movable connecting rod 4 and connecting lever 6 output are on same straight line, therefore, the structural design of " sight alignment formula " makes the bounce of breaker vacuum pipe moving contact 32 act on driving shaft 1 like this, hardly moment of torsion is produced to driving shaft 1, effectively can suppress the spring of breaker vacuum pipe moving contact 32.
More than that better enforcement of the present utility model is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modifications or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
