Abstract
The utility model discloses a crank arm structure of a high-voltage disconnecting switch. A reinforcing rib (5) is arranged at the connecting position of a crank arm pipe (2) and a crank arm plate (4), a protrusion (6) is arranged at the operation position of the crank arm plate (4). When operation force is acted on the protrusion (6) arranged on a crank arm, the operation force is reduced due to the fact that the protrusion (6) reduces the contact area, the reinforcing rib (5) has functions of reinforcement and stabilization, and therefore the operation force can not enable the crank arm to be bent and deformed.
Description
Technical field
The utility model relates to a kind of high voltage isolator, particularly the connecting lever structure in a kind of rotating shaft of high voltage isolator.
Background technology
High voltage isolator is to isolate, connect, changing the device of getting in touch between electrified body and the electrical equipment under the non-loaded state of circuit in the electrical power distribution system.Therefore the correctness and the stability of high voltage isolator operation are the guarantees of electrical power distribution system safe handling.Existing high voltage isolator all is main shaft and the operating mechanism that connects high voltage isolator by connecting lever, the action of operating mechanism drives the action that main shaft is realized high voltage isolator by the conversion of connecting lever, therefore the structure and the characteristic of connecting lever also are links important in the electrical power distribution system, the size of connecting lever intensity directly determined main shaft the anglec of rotation accurately whether.Existing connecting lever is welded by a connecting lever pipe and a connecting lever plate, owing to be Welding Structure, the connecting lever plate has metaboly, caused the main axis rotation angle of high voltage isolator inaccurate, thereby phenomenons such as the high voltage isolator divide-shut brake is not in place, operating physical force instability can occur, made the high voltage isolator heating easily, electricity decreases big, directly influence the life-span of high voltage isolator, cause economic loss, may cause the electrical power distribution system major accident during problem especially severe.
The utility model content
The purpose of this utility model is a kind of high voltage isolator connecting lever structure that can solve deficiency in the existing structure of design.
Technical solutions of the utility model are: a kind of high voltage isolator connecting lever structure, comprise connecting lever pipe and connecting lever plate, and it is characterized in that, be provided with reinforcement at connecting lever pipe and connecting lever plate junction, be provided with projection in the operating position of connecting lever plate.
The high voltage isolator connecting lever structure that the utility model provides, projection reduces contact area when connecting lever is connected with operating mechanism, thereby reduce friction, even reinforcement is subjected to connecting lever when operation excessive also being unlikely to of axial thrust load makes connecting lever generation elasticity or flexural deformation, guaranteed stability, the reliability of connecting lever attended operation mechanism and high voltage isolator rotating shaft.
Description of drawings
Fig. 1 is the structural representation of existing high voltage isolator connecting lever structure;
Fig. 2 is the structural representation of an embodiment of the utility model high voltage isolator connecting lever structure.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, rotating shaft 2, connecting lever pipe 3, the pin 4 that rises, connecting lever plate 5, reinforcement 6, projection
As shown in Figure 2, the utility model high voltage isolator connecting lever structure comprises connecting lever pipe 2 and connecting lever plate 4, and feature is to be provided with reinforcement 5 at connecting lever pipe 2 and connecting lever plate 4 junctions, is provided with projection 6 in the operating position of connecting lever plate 4.
When operating physical force acts on projection 6 on the connecting lever plate 4, owing to projection 6 has reduced contact area operating physical force has also been reduced, and reinforcement 5 has also played reinforcement, stabilization, so operating physical force can not make connecting lever plate 4 occur bending and deformation.
