Description
The utility model belongs to the ac high-voltage on-load switch of being with arc-control device.
In having the ac high-voltage on-load switch of arc-control device, because arc contact knife and arcing contact disjunction, fit arrangement design and movable touch knife disjunction, fit arrangement design unreasonable, cause contact generation arcing and melting welding phenomenon, more and more the needs of the domestic power system development of incompatibility.
The purpose of this utility model provides a kind of arc contact knife, arcing contact and movable touch knife disjunction, pass sum velocity is fast, is difficult for producing the novel high-pressure on-load switch of arcing and melting welding phenomenon.
The purpose of this utility model is realized by following technical scheme: pass the high voltage load switch that constitutes from mechanism, fuse etc. by base (1), insulator (2), movable touch knife (3), arc contact knife (4), arcing contact (5), arc control device (6), spring energy-storage, the end face of its arcing contact (5) is an inclined-plane, the spring leaf (8) that is fixed on the arc control device framework (7) by some screws (9) is supported on one jiao of arc control device (6), and makes it to be in the centre position of two arc extinguishing panels.
The afterbody of arc contact knife (4) is fixed with support (10), is connected the middle part of movable touch knife (3) with arc contact knife (4) with axle, is provided with extension spring (11) between the afterbody of the extension spring hole of support (10) and movable touch knife (3).
Operating grip (12) is fixed on an end of driving shaft (13), the other end is fixed with two axles (16) (17) of connecting lever (14) by triangle connecting plate (15) and is connected with locking board (18), also be provided with on the triangle connecting plate (15) and locking board (18) the contacted restriction post in end (19), be fixed with spring base (22) (23) respectively on the axle sleeve (20) of driving shaft (13) and the driven axle (21), be provided with between the two and close the push rod (36) that closes energy-stored spring (24) and have a slotted hole, also being provided with limit pull rod (25) on the spring base (23) flexibly connects with limit lever (26), driven axle (21) is connected with locking board (18) by connecting lever (33), and the link stopper (27) that is fixed on the axle sleeve (20) contacts with the end face of limit lever (26); Also be provided with spring base (28) (29) on driven axle (21) and the base (1) and be provided with disjunction energy-stored spring (30) between the two.
The axle (16) that connecting lever (14) is connected with triangle connecting plate (15) is the special-shaped axis of band groove and two platforms, and the tripping plate (31) that has square hole is installed at the platform place, and the semi-round groove on it crouches on the elastic push rod (32) that is fixed on the base (1).
Further describe the technical program below in conjunction with drawings and Examples:
Fig. 1 is that schematic diagram is closed in arcing contact, arc contact knife structure and disjunction, pass;
Fig. 2 is Figure 1A-A generalized section;
Fig. 3 is a spring energy-storage transmission mechanism schematic diagram;
Fig. 4 looks the partial structurtes generalized section for Fig. 3 left side.
By Fig. 1,2 thickness is shown is that 1.5 millimeters arc contact knife (4) is to do in 3 millimeters arc control device (6) crack to close to close in gap width, the disjunction campaign, arcing contact (5) is supported on the lower right corner of arc control device framework (7) with screw (9) by two overlapping spring leafs (8), free state arcing contact (5) is in the centre of two arc extinguishing blanks, fashionable in the pass, arc contact knife (4) enters arc control device (6) from the slit of the upper left corner, when bumping against with arcing contact (5), because the ramp effect of arcing contact (5), self push arcing contact (5) to spring leaf (8) on one side, make arc contact knife (4) slide into arcing contact (5) below, and arcing contact (5) sets back it in this moment by spring leaf (8), make arc contact knife (4) stop at arcing contact (5) below; When disjunction; arc contact knife (4) drives motion upward by movable touch knife (3); because two cuttves connect with axle; arc contact knife (4) is upwards outwards to be pulled below arcing contact (5); below up to the end of arc contact knife (4) from arcing contact (5) is drawn out; under the effect of disjunction energy-stored spring (30) and arc contact knife extension spring (11); hypervelocity breaks away from arcing contact (5); its speed is movable touch knife (3) breaking speed and the relative movable touch knife of arc contact knife (4) (3) movement velocity sum; arc contact knife (4) is for stopping (3) moments disjunction again of hysteresis movable touch knife by arcing contact (5) like this; and breaking speed is high; burn so promptly protected the movable touch knife (3) of major loop to exempt from electric arc, improved the current interruption ability of arc contact knife (4) again greatly.
Fig. 3,4,5 illustrate, upwards driving handle (12) driving shaft (13) rotates, axle sleeve (20) is under the effect of link stopper (27) and limit lever (26), do not rotate, connecting lever (14) rotates with driving shaft (13) inhour, locking board (18) is under the clamping and the acting in conjunction of triangle connecting plate (15) of axle (16) and restriction post (19), can only move upward with connecting lever (14), make driven axle (21) backward rotation by connecting lever (33), pass between the spring base (22) (23) is closed energy-stored spring and is drawn back energy storage, at this moment, disjunction energy-stored spring (30) is also by the while energy storage, be pulled to the below with the limit pull rod (25) of driven axle (21) interlock, on continuing, operating grip (12) pushes away, the adjustment nut (34) of limit pull rod (25) contacts and limit lever (26) is rotated, when breaking away from postioning abutment (27), axle sleeve closes energy-stored spring (24) in the pass active force orders about down, high speed rotating, the big pull bar (35) that is coupling with it closes a floodgate movable touch knife (3) at a high speed, and the axostylus axostyle of spring base this moment (22) is got back to the lower position of push rod (36) slotted hole.
When breaking operation, pull down fixed handle (12), connecting lever (14) clockwise rotates, because the square hole of tripping plate (31) is meshed (accompanying drawing is not shown) so tripping plate (31) also rotates thereupon with two platforms of axle (16), when the semi-round groove of tripping plate (18) crouches on elastic push rod (32), axle (16) is rotated relative to triangle connecting plate (15), make the end of locking board (18) enter axle (16) groove in a flash, driven axle (21) loses restriction, under the effect of disjunction energy-stored spring (30), order about down, clockwise high speed rotating, and make clockwise high speed rotating of axle sleeve (20) by push rod (36), drive big pull bar (35) and make movable touch knife (3) high speed separating brake, axle sleeve (20) is got back to the combined floodgate ready position again.
The utility model has the advantages that:
1. compact conformation is reasonable in design, and it is little to compare the like product volume, but the electrical insulation properties height.
Movable touch knife close close, the breaking speed height, 40 milliseconds of breaks close and close 50 milliseconds of times, have overcome contact arcing and Welding Phenomena.
3. arcing contact disjunction synchronism is consistent, and current interruption is effective.
