The slider cooperates with the handle of the circuit breaker in transmission.

[0048] The specific implementation of the circuit breaker device of the present invention is further described below in conjunction with the embodiments given in the accompanying drawings. The circuit breaker device of the present invention is not limited to the description of the following embodiments.

[0049] like Figure 1-8 FIG. 1 is an embodiment of a circuit breaker device according to the present invention.

[0050] like Figure 1 As shown, the circuit breaker device of this embodiment includes a manual operating mechanism m and a circuit breaker 100. The circuit breaker 100 has four working states, namely, a closing state, a tripping state, an opening state, and a re-arresting state. The manual operating mechanism m is in transmission cooperation with the circuit breaker 100. External force can drive the circuit breaker 100 to close (that is, switch from the opening state to the closing state), open (switch from the closing state to the opening state), and re-arrest (switch from the tripping state to the opening state via the re-arresting state) through the manual operating mechanism m. Further, the circuit breaker 100 includes a handle 100-0. The manual operating mechanism m is in transmission cooperation with the handle 100-0 to drive the handle 100-0 to swing, thereby driving the circuit breaker 100 to close, open, and re-arrest.

[0051] It should be noted that the circuit breaker 100 includes an energy storage operating mechanism, which can be implemented by existing technologies, such as the four-link-five-link switching method of the existing technology, and will not be described in detail here.

[0052] Combination Figure 1-5As shown in 7-8, the hand-operated mechanism m includes an operating handle 0, an operating shaft 1, a transmission structure, a slider 4 and a guide rail structure 5. The operating handle 0 is swung by external force operation and drives the operating shaft 1 to rotate around its own axis. The operating shaft 1 is connected to the slider 4 through the transmission structure and is used to drive the slider 4 to move back and forth along the guide rail structure 5. The slider 4 is matched with the handle 100-0 to drive the handle (100-1) to swing to close, open and re-close the circuit breaker 100. Furthermore, the operating handle 0 has an operating handle closing position p10, an operating handle tripping position p20, an operating handle opening position p30 and an operating handle re-locking position (the operating handle closing position p10 and the operating handle re-locking position are located at both ends of the swing stroke of the operating handle 0), the slider 4 has a slider closing position, a slider tripping position, a slider opening position and a slider re-locking position (the slider closing position and the slider re-locking position are located at both ends of the moving stroke of the slider 4), and the handle 100-1 has a handle closing position p1, a handle tripping position p2, a handle opening position p3 and a handle re-locking position p4 (the handle closing position p1 and the handle re-locking position p4 are located at both ends of the swing stroke of the handle 100-1), which respectively correspond to the closing state, tripping state, opening state and re-locking state of the circuit breaker 100; that is, the four positions of the operating handle 0, the four positions of the slider 4, and the four positions of the handle 100-1 correspond to the four states of the circuit breaker 100, respectively.

[0053] like Figure 1-2 As shown, the hand-operated mechanism m also includes a mechanism housing 10, an operating shaft 1 is rotatably arranged on the mechanism housing 10 around its own axis, a guide rail structure 5 is fixedly arranged on the mechanism housing 10, and a slider 4 is slidably arranged on the guide rail structure 5. Further, the mechanism housing 10 includes a mechanism housing top plate 10t, a mechanism housing side plate 10s and a mechanism housing foot 10f, two mechanism housing side plates 10s are opposite and respectively connected to the mechanism housing top plate 10t by bending, and the two mechanism housing side walls 10s are provided with a mechanism housing foot 10f, and the mechanism housing foot 10f is fixedly arranged on the circuit breaker housing 100-0 of the circuit breaker 100; the operating shaft 1 is rotatably arranged on the mechanism housing top plate 10t around its own axis, and the guide rail structure 5 is fixedly arranged on the mechanism housing top plate 10t and located between the two mechanism housing side plates 10s.

[0054] Combination Figure 7-8As shown, when the circuit breaker 100 switches between the closed state and the open state, the swing angle of the handle 100-1 is α0 (that is, the angle between the handle 100-1 at the handle closed position p1 and the handle 100-1 at the handle open position p3), and the swing angle of the operating handle 0 is β0 (that is, the angle between the operating handle 0 at the operating handle closed position p10 and the operating handle 0 at the operating handle open position p30); when the circuit breaker 100 switches from the closed state to the tripped state, the handle 100-1 swings from the handle closed position p1 to the handle open position p30. The operating handle 0 is in the tripping position p2, and the handle 100-1 drives the operating handle 0 to swing from the operating handle closing position p10 to the operating handle tripping position p20 through the transmission structure and the operating shaft 1. The swing angle of the handle 100-1 is α1 (that is, the angle between the handle 100-1 at the handle closing position p1 and the handle 100-1 at the handle tripping position p2), and the swing angle of the operating handle 0 is β1 (that is, the angle between the operating handle p10 at the operating handle closing position p10 and the operating handle 0 at the operating shaft tripping position P20); β1 / β0>α1 / α0. When the circuit breaker 100 switches from the closing state to the tripping state, the operating handle 0 has a larger ratio of the tripping stroke (that is, β1) to the opening and closing stroke (that is, β0) than the handle 100-1, and the position change is more obvious and clear, so that the operator can more intuitively judge the current state of the circuit breaker 100 and avoid accidents due to misjudgment.

[0055] Furthermore, 0.4≤β1 / β0≤0.6, so that the operating handle tripping position p20 of the operating handle 0 is closer to the middle position between the operating handle closing position p10 and the operating handle opening position p20, so that when the circuit breaker 100 switches from the closing state to the tripping state, the position change of the operating handle 0 is more obvious. β1 / β0 is preferably 0.5.

[0056] Specifically, when the circuit breaker 100 is switched from the tripped state to the open state, the swing angle of the handle 100-1 (i.e., the angle between the handle 100-1 at the handle tripped position p2 and the handle 100-1 at the handle open position p3) is α2, and the swing angle of the operating handle 0 (i.e., the angle between the operating handle 0 at the operating handle tripped position p20 and the operating handle 0 at the operating handle open position p30) is β2, 2 / 3≤β1 / β2≤3 / 2. β1 / β2 is preferably 1, that is, β1=β2.

[0057] Furthermore, α1<β1.

[0058] Furthermore, α2<β2.

[0059] For example, when the circuit breaker 100 switches between the closed state and the open state, the swing angle of the operating handle 0 is β0=90° (that is, the angle between the operating handle 0 at the closed position p10 of the operating handle and the operating handle 0 at the open position p30 of the operating handle is 90°), and the swing angle of the handle 100-1 is α0=32° (that is, the angle between the handle 100-1 at the handle closed position p1 and the handle 100-1 at the handle open position p3 is 32°); when the circuit breaker 100 switches from the closed state to the tripped state, the swing angle of the operating handle 0 is β1=45° (that is, the angle between the operating handle 0 at the closed position p10 of the operating handle and the operating handle 0 at the tripped position p20 of the operating handle is 45°), and the swing angle of the handle 100-1 is α1=7° (that is, the angle between the handle closed position p1 The circuit breaker 100 is switched from the tripped state to the open state, and the swing angle of the operating handle 0 is β2=45° (that is, the angle between the operating handle 0 at the operating handle tripped position p20 and the operating handle 0 at the operating handle opening position p30 is 45°), and the swing angle of the handle 100-1 is α2=20.6° (that is, the angle between the handle 100-1 at the handle tripped position p2 and the handle 10-1 at the handle opening position p3), α0≈α1+α2; it can be seen that β1:β2=1:1, α1:α2=7:20.6, β1 / β0>α1 / α0, and the operating handle 0 has a more obvious position change than the handle 100-1 when the circuit breaker 100 is switched from the closed state to the tripped state.

[0060] like Figure 2-6 As shown, it is a realization method of the transmission structure:

[0061] The transmission structure includes a first transmission structure t1 and a second transmission structure t2. When the circuit breaker 100 is switched from the closed state to the tripped state, the operating shaft 1 is connected to the slider 4 through the first transmission structure t1, that is, the handle 100-1 swings from the handle closed position p1 to the handle tripped position p2 and drives the slider 4 to move from the slider closed position to the slider tripped position, and the slider 4 drives the operating handle 0 to swing from the operating handle closed position p10 to the operating handle tripped position p20 through the first transmission structure t1 and the operating shaft 1. When the circuit breaker 100 is switched from the tripped state to the open state, the operating shaft 1 is connected to the slider 4 through the second transmission structure t2, that is, the operating handle 0 is driven by external force from the operating handle tripped position p20 to the operating handle re-engagement position and drives the slider 4 from the slider tripped position to the slider re-engagement position through the operating shaft 1 and the second transmission structure t2. The slider 4 simultaneously drives the handle 100-1 to swing from the handle tripped position p2 to the handle re-engagement position p4, so that the circuit breaker 100 is re-engaged (that is, the energy storage operating mechanism of the circuit breaker 100 is re-engaged, and the circuit breaker 100 is in the re-engagement state at this time). Then, the handle 100-1 swings and resets from the handle re-engagement position p4 to the handle opening position p3 and drives the slider 4 to move from the slider re-engagement position to the slider opening position. The slider 4 simultaneously drives the operating handle 0 to swing from the operating handle re-engagement position to the operating handle opening position p30 through the second transmission structure t2 and the operating shaft 1.

[0062] like Figure 2-6 As shown, the first transmission structure t1 includes a first gear 3-1 that is transmission-connected to the operating shaft 1 and rotates synchronously on the same axis, and a first rack 4-4 that is arranged on the slider 4, and the first gear 3-1 meshes with the first rack 4-4; the second transmission structure t2 includes a second gear 3-2 that is transmission-connected to the operating shaft 1 and rotates synchronously on the same axis, and a second rack 4-5 that is arranged on the slider 4, and the second gear 3-2 meshes with the second rack 4-5. The transmission structure has a simple structure and reliable transmission.

[0063] Further, the axial direction of the operating shaft 1 is perpendicular to the moving direction of the slider 4. Specifically, the axial direction of the operating shaft 1 is perpendicular to the slider mainboard 4-0 of the slider 4.

[0064] As another embodiment, the axial direction of the operating shaft 1 is parallel to the moving direction of the slider 4. In this case, the first transmission structure t1 and the second transmission structure t2 can be realized by two sets of worm gear structures, which is a structure that can be realized by technical personnel in this field according to the prior art and will not be described in detail here.

[0065] Furthermore, the pitch circle radius of the first gear 3-1 is r1, the pitch circle radius of the second gear 3-2 is r2, r1<r2; the distance between the first rack 4-4 and the operating shaft 1 is d1, the distance between the second rack 4-5 and the operating shaft 1 is d2, d1<d2.

[0066] Specifically, when the circuit breaker 100 is switched from the closed state to the tripped state, the swing angle of the operating handle 0 is β1=45°, and the stroke traveled by the handle 100-1 driving the slider 4 is the first stroke, the first stroke=7m, 2π(r1)=7×8, and r1=8.9mm; when the circuit breaker 100 is switched from the tripped state to the open state, the swing angle of the operating handle 0 is β2=45°, and the stroke traveled by the handle 100-1 driving the slider 4 is the second stroke, the second stroke=20.6m, 2π(r2)=(20.6)×8, and r2=26.2mm.

[0067] Furthermore, the first gear 3-1 and the second gear 3-2 are coplanar and integrally structured to form a transmission member 3, which is conducive to simplifying the structure of the circuit breaker device and reducing the number of parts. Furthermore, the first gear 3-1 and the second gear 3-2 are both sector gears, and the central angles of the two sector gears are concentric and continuously arranged.

[0068] As another embodiment, the first gear 3-1 and the second gear 3-2 may also be arranged side by side along the axial direction of the operating shaft 1. Of course, the positional relationship between the first rack 4-4 and the second rack 4-5 also needs to be adjusted accordingly.

[0069] Further, the hand-operated mechanism m also includes a transmission seat 2, which is rotatably arranged on the mechanism housing 10, and the two ends of the hand-operated shaft 1 are respectively connected to the operating handle 0 and the transmission seat 2 in a transmission manner, that is, the hand-operated shaft 1 is rotatably arranged on the mechanism housing top plate 10t around its own axis through the transmission seat 2, and the transmission member 3 is arranged on the transmission seat 2 and rotates synchronously therewith. Further, the mechanism housing top plate 10t is provided with a mechanism housing shaft hole 10-0, and the transmission seat 2 is rotatably arranged in the mechanism housing shaft hole 10-0, and the two ends of the hand-operated shaft 1 are respectively connected to the operating handle 0 and the transmission seat 2 in a detachable manner.

[0070] Furthermore, the first rack 4 - 4 includes a plurality of first holes arranged side by side on the slider 4 , which mesh with the gear teeth of the first gear 3 - 1 , which is beneficial to simplify the structure of the slider 4 , facilitate manufacturing and production, and save costs.

[0071] Furthermore, the second rack 4-5 includes a plurality of second holes arranged side by side on the slider 4, which mesh with the gear teeth of the second gear 3-2, which is beneficial to simplify the structure of the slider 4, facilitate production and save costs.

[0072] As another embodiment, the first rack 4 - 4 and / or the second rack 4 - 5 is formed by a plurality of teeth arranged side by side.

[0073] like Figure 2-5 As shown, the slider 4 includes a slider main board 4-0 and a slider driving part 4-3 arranged on the slider main board 4-0, and the slider driving part 4-3 is in transmission cooperation with the handle 100-1.

[0074] like Figure 5 As shown, it is an implementation of the slider driving part 4-3: the slider driving part 4-3 includes two driving hands 4-30 arranged opposite to each other, and the handle 100-1 is inserted between the two driving hands 4-30 and respectively cooperates with the two driving hands 4-30 in transmission. Further, the driving hand 4-30 is a V-shaped structure, which includes a first plate and a second plate, one end of the first plate is connected to the slider main board 4-0, and the other end is bent and connected to the second plate; the tips of the V-shaped structures of the two driving hands 4-30 are opposite to each other, and the handle 100-1 is inserted between the tips of the V-shaped structures of the two driving hands 4-30, which is conducive to reducing the friction between the driving hands 4-30 and the handle 100-1, and ensuring the reliable and stable operation of the hand-operated mechanism m. Furthermore, the slider 4 also includes a mainboard avoidance hole 4-31 arranged on the slider mainboard 4-0 and corresponding to the handle 100-1, one end of two driving hands 4-30 is connected to a pair of side bends of the mainboard avoidance hole 4-31, and the mainboard avoidance hole 4-31 and the driving hands 4-30 are cut from the slider mainboard 4-0, which is conducive to simplifying the structure of the slider 4-31.

Further, the planes where the first transmission wall 4-6 and the second transmission wall are located are perpendicular to the side where the slider main board 4-0 is located, and in the moving direction of the slider 4, the first transmission wall 4-6 and the second transmission wall are arranged side by side. Further, a slider side wall 4-1 of the slider 4 serves as a second transmission wall.

[0076] like Figure 2-5As shown, the slider 4 also includes a slider side wall 4-1 and a slider guide 4-2. The two slider side walls 4-1 are opposite to each other and one end is respectively bent and connected to the two ends of the slider main board 4-0.
