[0031] like Figure 1-4 As shown, the electric operating mechanism of the reclosing circuit breaker created by the present invention includes a control handle 200 and an actuator, the actuator includes a slider 400 for connecting the control handle 200, and a first rotating member 810 and a second rotating member 820 arranged along the moving direction of the slider 400, the first rotating member 810 is connected to the motor 140, and the motor 140 can drive the first rotating member 810 to rotate, so that the first rotating member 810 pushes the slider 400 and the second rotating member 820 in sequence;

[0032] When the first rotating member 810 pushes the slider 400 , the slider 400 drives the control handle 200 to move toward one side of the second rotating member 820 ;

[0033] When the first rotating member 810 pushes the second rotating member 820 , the second rotating member 820 rotates in the opposite direction of the first rotating member 810 , and pushes the slider 400 to drive the control handle 200 to move toward one side of the first rotating member 810 .

[0034] The electric operating mechanism of the reclosing circuit breaker created by the present invention pushes the slider 400 to move from different positions through the first rotating member 810 and the second rotating member 820 driven by the first rotating member 810, thereby ensuring that the thrust on the slider 400 is stable and of the same size, so that the thrust of the slider 400 acting on the control handle 200 remains parallel to the movement direction of the control handle 200, avoiding the occurrence of a "dead point" position. Not only can a motor 140 with low power, small size and low cost be selected, but also the reliability and life span can be effectively improved.

[0035] The following is combined with Figures 1 to 9 The given embodiments further illustrate the specific implementation of the electric operating mechanism of the reclosing circuit breaker created by the present invention. The electric operating mechanism of the reclosing circuit breaker created by the present invention is not limited to the description of the following embodiments.

[0036] like Figure 1-5As shown, the first rotating member 810 and the second rotating member 820 are respectively provided with first gear teeth 811 and second gear teeth 821 around them, and the side of the slider 400 is provided with multiple pushing grooves 550. The first gear teeth 811 and the second gear teeth 821 can be respectively inserted into the pushing grooves 550 to push the slider 400 to move, and the first gear teeth 811 can push the second gear teeth 821 to drive the second rotating member 820 to rotate.

[0037] See also Figure 2 The first rotating member 810 rotates clockwise under the drive of the motor 140, the first gear tooth 811 on the first rotating member 810 is inserted into the pushing groove 550 and pushes the slider 400 to move upward, and the slider 400 drives the control handle 200 to move in the closing direction to Figure 3 position, at which time the first gear tooth 811 is not in contact with the second rotating member 820, and the second rotating member 820 is idle under the action of the slider 400;

[0038] See also Figure 3 , the control handle 200 is closed in place, if the first rotating member 810 continues to rotate clockwise under the drive of the motor 140, the first gear tooth 811 will contact the second gear tooth 821 of the second rotating member 820;

[0039] See also Figure 4 ,Depend on Figure 2 The first rotating member 810 continues to rotate clockwise under the drive of the motor 140, and the first gear 811 pushes the second gear 821 to make the second rotating member 820 rotate counterclockwise. The second rotating member 820 pushes the slider 400 downward through the second gear 821, so that the slider 400 drives the control handle 200 to move to the opening position. Figure 1 Below the position of the middle slider 400, the control handle 200 opens the gate in place, and if it has been tripped, it is re-tripped at the same time.

[0040] Specifically, the first rotating member 810 of this embodiment is an incomplete gear, and the first rotating member 810 includes two pairs of first gear teeth 811 arranged at intervals, and the two pairs of first gear teeth 811 are arranged on both sides of the first rotating member 810 opposite to each other, and the gap between the two pairs of first gear teeth 811 is used to avoid the second rotating member 820 when the first gear teeth 811 push the slider 400, and to avoid the slider 400 when the first gear teeth 811 push the second rotating member 820. In addition, the first rotating member 810 and the second rotating member 820 can also be connected by other parts, such as adding a gear between the first rotating member 810 and the second rotating member 820, which all belong to the protection scope of the invention.

[0041] The second rotating member 820 of this embodiment is a full-tooth gear, and a plurality of second gear teeth 821 are evenly distributed around the second rotating member 820. Of course, the second rotating member 820 is not limited to a full-tooth gear, and the specific number of teeth is determined by the opening and closing stroke of the reclosing circuit breaker, and the second rotating member 820 and the pushing groove 550 on the slider 400 will not be disengaged. In addition, the second rotating member 820 can also push the slider 400 to move in other ways, for example, the second rotating member 820 is provided with a connecting rod connected to the control handle 200, and when the second rotating member 820 rotates, the connecting rod drives the handle to move in the opening direction, which belongs to the protection scope of the invention.

[0042] It is understandable that the number of teeth of the first rotating member 810 can be a single tooth or multiple teeth to form an incomplete gear set, and the number of teeth of the first rotating member 810 depends on the diameter of the first rotating member 810, the spacing of the pushing grooves 550 on the slider 400, and the stroke of the reclosing circuit breaker. In addition, the incomplete gear set of the first rotating member 810 can be a single set or multiple sets, and multiple sets of incomplete gear sets can facilitate shortening the opening and closing time.

[0043] See also Figure 8 , one end of the slider 400 close to the first rotating member 810 is recessed to form a closing adjustment groove 551, the first rotating member 810 can slide into the bottom of the closing adjustment groove 551, push the bottom of the closing adjustment groove 551 to drive the control handle 200 to move in the closing direction, and the control handle 200 is closed in place when the first rotating member 810 is separated from the bottom of the closing adjustment groove 551; and / or one end of the slider 400 close to the second rotating member 820 is recessed to form an opening adjustment groove 552, the second rotating member 820 can slide into the bottom of the opening adjustment groove 552, push the bottom of the opening adjustment groove 552 to drive the control handle 200 to move in the opening direction, and the control handle 200 is opened in place when the second rotating member 820 is separated from the bottom of the opening adjustment groove 552. The closing adjustment groove 551 and the opening adjustment groove 552 can not only facilitate the insertion of the first rotating member 810 and the second rotating member 820, but also can be used to adjust the stroke of opening and closing. The depth of the closing adjustment groove can determine when the first rotating member 810 is separated from the bottom of the closing adjustment groove 551, that is, when the first rotating member 810 is disengaged from the first rotating member 810, thereby determining the closing stroke. Similarly, the depth of the opening adjustment groove 552 can also determine the opening stroke.

[0044] Specifically, the slider 400 is in a U-shaped structure, including two side plates 431 arranged opposite to each other, and a top plate 432 connected between the top sides of the two side plates 431. The height of the two side plates 431 is less than the control handle 200, so that the height of the top plate 432 is lower than the control handle 200. The top plate 432 is provided with a handle slot 410 sleeved on the control handle 200, wherein the side plate 431 close to the first rotating member 810 and the second rotating member 820 is provided with a plurality of push slots 550. The flat design of the top plate 432 being lower in height than the control handle 200 effectively overcomes the problem of large space occupied by the gear and rack in the background art, and can effectively reduce the product height of the reclosing circuit breaker.

[0045] like Figure 7-9 As shown, it also includes a guiding mechanism for limiting the slider 400, which allows the slider 400 to move only in parallel with the moving direction of the control handle 200. The guiding mechanism includes guide rails 512 relatively arranged on both sides of the slider 400, and the outer sides of the two side plates 431 are respectively provided with sliding plates 433 inserted into the guide rails 512 on both sides for sliding fit.

[0046] Specifically, the two guide rails 512 are respectively Z-shaped structures, and the two guide rails 512 respectively include a bottom edge 5121 and a top edge 5122, and a connecting edge 5123 obliquely connected between the bottom edge 5121 and the top edge 5122. The bottom edges 5121 of the two guide rails 512 are respectively fixed on the bottom plate 818, so that the top edge 5122 and the bottom plate 818 are separated to form a guide groove, and the bottom sides of the two side plates 431 extend outward to form sliding plates 433. The two sliding plates 433 are respectively inserted into the corresponding guide grooves on both sides for sliding cooperation, and are limited between the corresponding top edges 5122 and the bottom plate 818.

[0047] like Figure 5-7 As shown, the first rotating member 810 is connected to the motor 140 via a clutch mechanism. The clutch mechanism is separated when the first rotating member 810 is manually operated, so that the first rotating member 810 cannot drive the motor 140 to rotate, thereby preventing the motor 140 from being damaged.

[0048] Specifically, a pad 812 and a pressure plate 813 are respectively provided on both sides of the first rotating member 810, and the pressure plate 813, the first rotating member 810 and the pad 812 are fixedly connected by a fastener 817. A hand lever 150 is provided on the pressure plate 813, and the fastener 817 can be a screw or a rivet. A pad hole and a clutch hole 814 sleeved on the output shaft 141 of the motor 140 are respectively provided in the middle of the pad 812 and the first rotating member 810. The clutch mechanism includes a clutch shaft 2 arranged in the clutch hole 814 and passing through the output shaft 141 of the motor 140, and a spring 3 connected between the output shaft 141 and the clutch shaft 2, and the spring 3 pushes the clutch shaft 2 toward the clutch hole The hole wall of 814 moves, and a plurality of inclined ratchet teeth are provided on the hole wall of the clutch hole 814, and a meshing surface 815 is respectively provided on one side of the plurality of ratchet teeth, and a sliding surface 816 is respectively provided on the other side of the plurality of ratchet teeth. When the output shaft 141 of the motor 140 rotates, the output shaft 141 drives the clutch shaft 2 to push the meshing surface 815 to rotate the first rotating member 810. When the hand lever 150 drives the pressure plate 813 to rotate, the pressure plate 813 drives the sliding surface 816 in the first rotating member 810 to push the clutch shaft 2 away, so that the clutch shaft 2 overcomes the action of the spring 33 and separates from the first rotating member 810, thereby preventing the output shaft 141 of the motor 140 from rotating, thereby avoiding damage to the motor 140.

[0049] After the clutch shaft 2 passes through the output shaft 141 of the motor 140, it is simultaneously limited in the first rotating member 810 by the pressing plate 813 and the cushion block 812, thereby limiting the first rotating member 810 and the motor 140. The clutch mechanism of this embodiment adopts an inner meshing method, and can also adopt an outer meshing method, and the number of clutch shafts 2 can be multiple, all of which belong to the protection scope of the invention.

[0050] like Figure 1 As shown, the reclosing circuit breaker created by the present invention includes a housing and a plurality of main circuit units arranged side by side in the housing. The housing is provided with a plurality of cavities corresponding to the main circuit units one by one. The four main circuit units are an A-phase main circuit unit, a B-phase main circuit unit, a C-phase main circuit unit and an N-phase main circuit unit arranged in sequence. The A-phase main circuit unit, the B-phase main circuit unit and the C-phase main circuit unit are connected to the live wire respectively, and the N-phase main circuit unit is connected to the neutral wire. The motor 140 is arranged in the cavities corresponding to the C-phase main circuit unit and the N-phase main circuit unit. By arranging the motor 140 in the cavities corresponding to the C-phase main circuit unit and the N-phase main circuit unit, not only can the space in the housing of the reclosing circuit breaker be effectively utilized to reduce the overall volume, but also the motor 140 can be avoided from being arranged above the zero-sequence current transformer to reduce the overall height.

[0051] like Figure 1As shown, the housing includes a middle cover with a "day" - shaped structure. The motor 140 is arranged on one side of the control handle 200. On the side of the middle cover corresponding to the motor 140 and the control handle 200, a mounting platform 910 is formed by protruding towards the top side, and a mounting groove 920 for accommodating the circuit board is formed on the other side of the middle cover. The actuator is mounted on the top side of the protrusion through the bottom plate 818. The actuator is integrated on a bottom plate 818, and then the bottom plate 818 is mounted on the housing, which can achieve modular assembly, making its assembly efficiency higher and more convenient in the production process.

[0052] The above content is a further detailed description of the present invention - creation in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present invention - creation is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention - creation belongs, without departing from the concept of the present invention - creation, several simple deductions or substitutions can be made, which should all be regarded as belonging to the protection scope of the present invention - creation.
