Abstract

The utility model provides a pivoting shaft electric connection mechanism of an outdoor alternating-current high-voltage isolation switch. A pivoting shaft is sleeved with a flange disc and a frame body in a penetrating manner; the flange disc and the frame body are jointly fixed on an insulator assembling end; a connection terminal is clamped between two parallel knife boards and is sleeved on the pivoting shaft; and an elastic locking and pressing unit of a shaft end of the pivoting shaft applies elastic pressure to a member of the pivoting shaft, and the two parallel knife boards are fixed on the frame body. With the adoption of the technical scheme, the pivoting shaft electric connection mechanism has the technical advantages of stable and reliable electric conduction contact and good electric conduction performance, and the manufacturing cost is greatly reduced; and the whole set of assembling and configuration is greatly simplified, the assembling strength is high, the impact resistance capability is strong and the fault rate is low.

Description

Outdoor AC high-voltage isolating switch pivot electrically connects mechanism

Technical field

The utility model relates to the disconnecting link pin-joint mechanism of electric power system high voltage isolator.

Background technology

The package assembly of the disconnecting link of electric power system outdoor high-voltage isolating switch and binding post and insulator, should guarantee enough mechanically stables and intensity, binding post is not rotated with insulated terminal and disconnecting link, existing pivot conduction connecting structure is all comparatively complicated, and electrical connection properties is also not satisfactory.A kind of Structural Tectonics of prior art, binding post is fixed on the conduction pivot, for guaranteeing electrical contact performance, reducing contact resistance, binding post is provided with the conduction parts that are flexible coupling between conduction pivot and disconnecting link, and must install outer cover additional, the protection electric connection structure is as the patented technology scheme of " conductive connection device of outdoor high-voltage isolation switch " of Chinese patent 200920305063.2 typical case comparatively; Another kind of is to adopt fingertip row electric connection structure between disconnecting link and conduction pivot, " a kind of low-resistance electric installation of high voltage isolator " as Chinese patent 200620024990.3, its binding post is undesirable with the position limiting structure of conduction pivot, bear the ability of longitudinal stress, a little less than shock-resistant ability, jump ring easily comes off, easily cause the binding post permanent deformation, and fingertip row and the self-closing power deficiency of contacting of conduction pivot, electrical contact performance is undesirable, is prone to burning phenomenon.Prior art also ubiquitous technical problem is: the parts such as binding post, flexible link, conduction pivot and fingertip row all need to expend a large amount of red copper materials, each this body structure of member and assembly structure are also comparatively complicated, strengthened manufacturing cost, the failure rate of mechanism is increased.

Summary of the invention

Goal of the invention of the present utility model is to provide that a kind of structure that is rotatably assorted, simple structure, conduction switching performance that fully satisfies binding post and disconnecting link and insulator is good, outdoor AC high-voltage isolating switch pivot low cost of manufacture electrically connects mechanism.Outdoor AC high-voltage isolating switch pivot of the present utility model electrically connects the mechanism technology scheme, its main technical content is: a kind of outdoor AC high-voltage isolating switch pivot electrically connects mechanism, pivot is coated with ring flange and support body, the positive stop lug boss section of pivot coordinates with the spacing deep gouge in ring flange bottom, restriction pivot position, jointly be fixed on insulator assembling end, binding post is located between two parallel knife plates, is set with on pivot, press the unit to apply elastic pressure to the member of suit pivot by the snap lock of pivot axle head, two parallel knife plates are fixed on support body.

the disclosed outdoor AC high-voltage isolating switch of the utility model pivot electrically connects the mechanism technology scheme, its binding post knife plate parallel with two directly fitted to conduct electricity and connected, press the unit to apply elastic pressure by snap lock, saved in existing structure be flexible coupling or fingertip row etc. in the middle of the conduction conducting parts, conductive contact is stable, reliably, electric conductivity is good, and guaranteed that binding post does not rotate with the rotation of insulator and disconnecting link, after binding post connects external cable, binding post and external cable can not exert an influence to a switch deciliter rotating operation, its each assembled component is simple in structure, a whole set of assembling structure is simplified greatly, also need not outer cover, assembling intensity is high, shock-resistant ability is strong, failure rate is low, its manufacturing cost decrease particularly.

Description of drawings

Fig. 1 has this outdoor AC high-voltage isolating switch pivot to electrically connect the contact direction structure figure of mechanism.

Fig. 2 and Fig. 3 are respectively A-A, the B-B sectional structure chart of Fig. 1.

Embodiment

The disclosed outdoor AC high-voltage isolating switch of the utility model pivot electrically connects mechanism, one is implemented structure as shown in drawings, pivot 1 upper sleeve through has ring flange 2 and support body 3, the positive stop lug boss section 10 of pivot 1 is absorbed in the spacing deep gouge of ring flange 2 bottoms, positive stop lug boss section 10 coordinates with the spacing deep gouge of ring flange 2, the axial position of restriction pivot 1 and position radially are fixed on pivot 1, ring flange 2 and support body 3 the top assembling end of insulator 8 jointly by sunk screw 7, make support body 3 upper surfaces keep level and smooth.The technical program is less demanding for the electric conductivity of pivot 1, and it can be that non-conducting material is made, and is preferably that electric conducting material makes, and can more lay particular emphasis on the pivot mechanical strength properties like this, thereby select more easily the good pivot manufactured materials of cost performance.Two parallel knife plate 4 outer ends connection contacts or tactile sons, its pivot assembling end is sandwiched in the both sides of binding post 5, jointly is sleeved on pivot 1, is fixed on support body 3 by bolt and nut; The axle head of pivot 1 presses pad, stage clip 6 and nut 9 in the unit to screw in by snap lock, applies elastic locking pressure, makes disconnecting link, binding post 5 and pivot be assemblied in reliably the assembling end of insulator 8.
