Because the continuous increase of net capacity, the rated operational voltage of new circuit breaker and rated short circuit drop-out current also improve thereupon, the power of operating mechanism and operational torque also reach bigger numerical value.At present, in the existing primary cut-out, operating mechanism is delivered to shackle rod by the interior connecting lever of installing in connecting lever rotating shaft and the connecting lever rotating shaft with actuating torque and carries out branch, closing operation, and shackle rod is to adopt the linear connector with being connected of interior connecting lever.In the operating process of carry out branch at primary cut-out, closing a floodgate, bump, need suitable lengthening connecting lever length for avoiding shackle rod and connecting lever rotating shaft; And, adopt the linear connector to be connected the restriction that makes the rotational angle of connecting lever be subjected to the connecting lever rotating shaft with connecting lever, generally can only rotate about 60 °, thereby it needs bigger actuating torque.And adopt bigger actuating torque summit or down during the summit on shackle rod reaches, be easy to generate bigger impact between connector and the connecting lever, its impulsive force is passed to each mechanism in the circuit breaker fully by shackle rod and connecting lever rotating shaft, thereby make that each link gear parts of circuit breaker and the mechanical part in the arc control device have been subjected to very big mechanical impact in operating process, the noise and the mechanical oscillation that produce in the operating process are bigger, the mechanical fatigue of the mechanical part that it causes and abrasion deformation, be to cause the breaker mechanical cause faults, have a strong impact on the job stability of circuit breaker, reduced the functional reliability and the life-span of circuit breaker.
In order to overcome the limitation of circuit breaker traditional design cathetus shape connector, reduce the mechanical impact that circuit breaker each link gear parts and the indoor mechanical part of breaker arc extinguishing in operating process are subjected to, improve the functional reliability and the useful life of circuit breaker, be necessary to carry out the exploitation of the new technology of primary cut-out mechanical structure.
The utility model content
The purpose of this utility model provides the connector that connects shackle rod and interior connecting lever in a kind of primary cut-out, to reduce primary cut-out link gear parts and the arc control device mechanical part mechanical impact power in operating process.
The technical solution of the utility model is: a kind of primary cut-out connector, comprise the connector body, one end of this connector body is used for connecting lever hinged, and its other end is used to connect adjusting screw(rod), and described connector body is being arranged to concave structure towards a side of connecting lever rotating shaft at least.
Described concave structure is the groove shaped structure that arcs of recesses constitutes.
Described connector body is the knee shape structure corresponding with arcs of recesses or groove shaped on the whole.
Described connector is made of the bending of aluminium alloy bar.
The utility model also provides a kind of primary cut-out, comprise the connector that connects shackle rod and connecting lever, one end of this connector is hinged on the connecting lever, and the other end connects shackle rod by adjusting screw rod, and described connector is being arranged to concave structure towards a side of connecting lever rotating shaft at least.
Described concave structure is the groove shaped structure that arcs of recesses constitutes.
Described connector body is the knee shape structure corresponding with arcs of recesses or groove shaped on the whole.
Described connector is made of the bending of aluminium alloy bar.
The two ends of described adjustment screw rod are respectively arranged with the opposite left-handed and right-handed thread of direction of rotation.
Two ends at described adjustment screw rod also are installed with lock nut respectively.
Adopt the arc-shaped joint structure, the utility model is compared with existing linear joint, has the following advantages:
1) adopts arc-shaped joint, with existing linear connector reduced in comparison the length of connecting lever, thereby reduced the operational torque of isolating switch, thereby when isolating switch carries out branch, feed motion, reduced the circuit breaker mechanical impact that the arc control device of each link gear parts and circuit breaker are subjected in operating process, noise and the mechanical oscillation in the operating process have been reduced, the mechanical fatigue and the abrasion deformation of mechanical part have been slowed down, the stability that helps circuit breaker work, functional reliability and the life-span that can improve circuit breaker.
2) adopt the design of arc connector, its in the actuating process of isolating switch, can reach shackle rod the summit or down during the summit and the impulsive force that produces between the connecting lever produce the elastic buffer effect, thereby can further reduce the mechanical impact that each mechanism of circuit breaker is subjected to.
3) because it has reduced the operational torque in the circuit breaker operating process, thereby help in operating process, using the novel operating mechanism that can carry out electrical control, as the motor direct-drive operating mechanism.
4) adopt the design of arc connector, power transmission shaft can be rotated in 120 ° or bigger angular range, thereby in operating process, realize the electrical control of motion process easily, because absolute angular displacement becomes big, can improve the quality of control, reduce departure.
5) adopt the design of arc connector, it is in the length of avoiding having shortened under connector and the connecting lever rotating shaft collision situation connecting lever, thereby can further dwindle connector in the isolating switch, connecting lever and the shared space of connecting lever rotating shaft, reduce the volume of driving gear of isolating switch.
