Description

Technical Field

[0001] This invention belongs to the field of switch cabinet technology, and specifically relates to a switch cabinet with a disconnecting switch. Background Technology

[0002] Chinese invention patent application CN104358834A discloses a sequential drive mechanism and a switch cabinet using the sequential drive mechanism. The sequential drive mechanism includes a driving incomplete gear for transmission connection with a power input device and two driven gears corresponding to the incomplete gear. The outer circumferential surface of the driving incomplete gear has a gear transmission section for transmission connection with the corresponding driven gear and an unloaded section for disengagement from the corresponding driven gear. Both the gear transmission section and the unloaded section have one segment arranged circumferentially, or both have two or more segments arranged alternately circumferentially. When the driving incomplete gear rotates, its gear transmission section and unloaded section can sequentially connect with the corresponding driven gear, thereby driving the driven gear according to a set driving sequence to achieve the corresponding driving requirements.

[0003] The aforementioned patent application scheme uses one driving incomplete gear and two driven incomplete gears to form two pairs of incomplete gear pairs. These pairs of incomplete gear pairs operate alternately to achieve sequential drive, such as driving a valve first and then a disconnect switch. However, in practice, the aforementioned patent application scheme has the following shortcomings: the first and last teeth of the incomplete gears are lower than the other teeth. During the initial meshing of the gear pairs driving the disconnect switch, because the disconnect switch is usually heavily loaded, it is prone to eccentricity during the reciprocating motion, resulting in tooth jamming (preventing rotation) or tooth misalignment (meshing over the first and last teeth). Increasing the rotation angle of the driven gears to reduce the force would make the driving gear too large. Summary of the Invention

[0004] This invention addresses the problem that existing switchgear with disconnecting switches uses a single driving incomplete gear and two driven incomplete gears in its sequential drive mechanism, which is prone to tooth misalignment or overloading when the disconnecting switch is under heavy load. This invention provides a switchgear with a disconnecting switch to avoid the problems caused by the disconnecting switch being under heavy load.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a switch cabinet with an isolating switch, wherein the switch cabinet with the isolating switch comprises:

[0006] Disconnect switch drive gear;

[0007] Valve drive gear;

[0008] Disconnect switch driven gear;

[0009] Valve driven gear;

[0010] The isolation locking assembly includes an active locking disc that rotates synchronously with the active gear of the isolation switch and a driven locking disc that rotates synchronously with the driven gear of the isolation switch.

[0011] Wherein, the disconnect switch driving gear, the valve driving gear, and the valve driven gear are non-full-tooth gears. The disconnect switch driving gear includes a first gear segment and a first non-tooth segment. The valve driving gear includes a second gear segment and a second non-tooth segment. The valve driven gear includes a third gear segment and a locking segment. The disconnect switch driven gear is a full-tooth gear. The active locking disc has a first locking arc distributed at the same angle as the first non-tooth segment of the disconnect switch driving gear. The active locking disc has a first releasing arc distributed at the same angle as the first gear segment of the disconnect switch driving gear. The driven locking disc has a second locking arc that can lock with the first locking arc. The driven locking disc has a second releasing arc corresponding to the first releasing arc.

[0012] Specifically, when the second non-tooth segment of the valve driving gear corresponds to the locking segment of the valve driven gear, the valve driven gear is locked and does not rotate; when the second gear segment of the valve driving gear corresponds to the third gear segment of the valve driven gear, the valve driving gear drives the valve driven gear to rotate.

[0013] Specifically, when the first non-tooth segment of the disconnector's driving gear corresponds to the position of the disconnector's driven gear, the disconnector's driven gear does not rotate; when the first gear segment of the disconnector's driving gear corresponds to the position of the disconnector's driven gear, the disconnector's driving gear drives the disconnector's driven gear to rotate.

[0014] Specifically, when the first locking arc of the active locking disc corresponds to the second locking arc of the driven locking disc, the driven locking disc is locked and does not rotate; when the first releasing arc of the active locking disc corresponds to the second releasing arc of the driven locking disc, the driven locking disc rotates with the driven gear of the isolating switch.

[0015] The switchgear with disconnecting switches of this invention splits a pair of incomplete gear pairs used for heavy-load output of the disconnecting switch operation into a pair of gear pairs: a driving gear and a driven gear, and a pair of locking pairs: a driving locking disc and a driven locking disc. The driven gear can rotate more than one revolution, reducing the meshing force transmitted between the driving and driven gear pairs, thereby avoiding problems such as tooth misalignment and overloading caused by heavy loads on the disconnecting switch. Separating the valve driving gear and the disconnecting switch driving gear from the same component ensures that the valve driven gear does not affect the disconnecting switch driving gear, the size of the disconnecting switch driving gear is not excessive, and it offers greater flexibility. This invention is applicable to various switchgears with disconnecting switches, such as outgoing line cabinets, incoming line cabinets, and isolation cabinets.

[0016] As an improvement, the number of teeth in the first gear segment of the disconnector's driving gear is greater than the number of teeth in the disconnector's driven gear.

[0017] As an improvement, the number of teeth in the first gear segment of the disconnecting switch's driving gear is twice the number of teeth in the disconnecting switch's driven gear. During the disconnecting switch's operation, the driven gear can rotate two revolutions, thus reducing the force on its shaft by half. This helps reduce stress and allows for a reduction in component size.

[0018] As an improvement, the disconnector drive gear, the valve drive gear, and the active locking disc are driven to rotate synchronously by the same splined shaft; the active locking disc is located between the disconnector drive gear and the valve drive gear.

[0019] As an improvement, the diameters of the second gear segment and the second non-tooth segment of the valve drive gear are basically equal; the diameter of the first locking arc of the drive locking disc is greater than the diameter of the first releasing arc; the diameter of the first gear segment of the disconnect switch drive gear is greater than the diameter of the first non-tooth segment; and the diameter of the second locking arc of the driven locking disc is greater than the diameter of the second releasing arc.

[0020] As an improvement, the number of teeth in the second gear segment of the valve driving gear and the third gear segment of the valve driven gear are equal.

[0021] As an improvement, the driven gear of the disconnect switch and the driven locking disc are driven to rotate synchronously by the same splined shaft.

[0022] As an improvement, the first gear segment and the first non-tooth segment of the disconnect switch driving gear each have only one segment and are connected end to end to form the outer peripheral surface of the disconnect switch driving gear; the second gear segment and the second non-tooth segment of the valve driving gear each have only one segment and are connected end to end to form the outer peripheral surface of the valve driving gear.

[0023] As an improvement, the disconnecting switch drive gear is provided with a limiting pin, and the switch cabinet with the disconnecting switch includes a bracket, the bracket is provided with a limiting block, and the limiting block limits the limiting pin.

[0024] As an improvement, the disconnector switch's drive gear is equipped with two limit switches, which are used to stop the sequential drive mechanism when the opening and closing of the gate are completed.

[0025] As an improvement, the switch cabinet with disconnect switch includes an input gear set, which includes three gear sets. Each gear set includes an input pinion and an input gear driven by the input pinion. The input gear of the gear set upstream along the force transmission direction and the adjacent input pinion downstream are driven by the same shaft.

[0026] As an improvement, the switch cabinet with the isolating switch includes a valve output gear set, which includes a first helical gear that rotates synchronously with the valve driven gear driven by the same spline shaft, a second helical gear that meshes with the first helical gear, and an involute gear that is driven by the second helical gear by the same shaft.

[0027] As an improvement, the switch cabinet with the disconnect switch includes a disconnect switch output gear set, which includes a large disconnect switch output gear that rotates synchronously with the disconnect switch driven gear by the same splined shaft, and a small disconnect switch output gear that meshes with the large disconnect switch output gear.

[0028] The beneficial effects of the switch cabinet with disconnecting switch of the present invention are: the pair of incomplete gear pairs used for heavy-load output of disconnecting switch operation are split into a pair of gear pairs of disconnecting switch driving gear and disconnecting switch driven gear, and a pair of locking pairs of driving locking disc and driven locking disc. The rotation of the disconnecting switch driven gear can exceed one revolution, thereby avoiding problems such as tooth misalignment and overloading caused by heavy load of disconnecting switch.

[0043] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.

[0044] See Figures 1 to 6 The present invention provides a switch cabinet with an isolating switch, the switch cabinet with the isolating switch comprising:

[0045] Disconnect switch drive gear;

[0046] Valve drive gear;

[0047] Disconnect switch driven gear;

[0048] Valve driven gear;

[0049] The isolation locking assembly includes an active locking disc that rotates synchronously with the active gear of the isolation switch and a driven locking disc that rotates synchronously with the driven gear of the isolation switch.

[0050] Wherein, the disconnect switch driving gear, the valve driving gear, and the valve driven gear are non-full-tooth gears. The disconnect switch driving gear includes a first gear segment and a first non-tooth segment. The valve driving gear includes a second gear segment and a second non-tooth segment. The valve driven gear includes a third gear segment and a locking segment. The disconnect switch driven gear is a full-tooth gear. The active locking disc has a first locking arc distributed at the same angle as the first non-tooth segment of the disconnect switch driving gear. The active locking disc has a first releasing arc distributed at the same angle as the first gear segment of the disconnect switch driving gear. The driven locking disc has a second locking arc that can lock with the first locking arc. The driven locking disc has a second releasing arc corresponding to the first releasing arc.

[0051] Specifically, when the second non-tooth segment of the valve driving gear corresponds to the locking segment of the valve driven gear, the valve driven gear is locked and does not rotate; when the second gear segment of the valve driving gear corresponds to the third gear segment of the valve driven gear, the valve driving gear drives the valve driven gear to rotate.

[0052] Specifically, when the first non-tooth segment of the disconnector's driving gear corresponds to the position of the disconnector's driven gear, the disconnector's driven gear does not rotate; when the first gear segment of the disconnector's driving gear corresponds to the position of the disconnector's driven gear, the disconnector's driving gear drives the disconnector's driven gear to rotate.

[0053] Specifically, when the first locking arc of the active locking disc corresponds to the second locking arc of the driven locking disc, the driven locking disc is locked and does not rotate; when the first releasing arc of the active locking disc corresponds to the second releasing arc of the driven locking disc, the driven locking disc rotates with the driven gear of the isolating switch.

[0054] The switch cabinet with disconnecting switch of the present invention splits a pair of incomplete gear pairs used for heavy-load output of disconnecting switch operation into a pair of gear pairs: disconnecting switch driving gear and disconnecting switch driven gear, and a pair of locking pairs: driving locking disc and driven locking disc. The rotation of the disconnecting switch driven gear can exceed one revolution, thereby avoiding problems such as tooth misalignment and overloading caused by heavy load of the disconnecting switch. The valve driving gear and the disconnecting switch driving gear are set separately instead of using the same component, so that the valve driven gear will not affect the disconnecting switch driving gear, and the disconnecting switch driving gear has greater freedom.

[0055] Example 1

[0056] See Figures 1 to 6 According to Embodiment 1 of the present invention, a switch cabinet with an isolating switch includes a sequential drive mechanism, which comprises:

[0057] Disconnect switch drive gear 1;

[0058] Valve drive gear 2;

[0059] Disconnect switch driven gear 3;

[0060] Valve driven gear 4;

[0061] The isolation locking assembly includes an active locking disc 5 that rotates synchronously with the active gear 1 of the isolation switch and a driven locking disc 6 that rotates synchronously with the driven gear 3 of the isolation switch.

[0062] Wherein, the disconnector drive gear 1, the valve drive gear 2, and the valve driven gear 4 are non-full-tooth gears. The disconnector drive gear 1 includes a first gear segment 11 and a first non-tooth segment 12. The valve drive gear 2 includes a second gear segment 21 and a second non-tooth segment 22. The valve driven gear 4 includes a third gear segment 41 and a locking segment 42. The disconnector driven gear 3 is a full-tooth gear. The active locking disc 5 has a first locking arc 51 distributed at the same angle as the first non-tooth segment 12 of the disconnector drive gear 1. The active locking disc 5 has a first releasing arc 52 distributed at the same angle as the first gear segment 11 of the disconnector drive gear 1. The driven locking disc 6 has a second locking arc 61 that can lock with the first locking arc 51. The driven locking disc 6 has a second releasing arc 62 corresponding to the first releasing arc 52.

[0063] Specifically, when the second non-tooth section 22 of the valve driving gear 2 corresponds to the locking section 42 of the valve driven gear 4, the valve driven gear 4 is locked and does not rotate; when the second gear section 21 of the valve driving gear 2 corresponds to the third gear section 41 of the valve driven gear 4, the valve driving gear 2 drives the valve driven gear 4 to rotate.

[0064] Specifically, when the first non-tooth segment 12 of the disconnector drive gear 1 corresponds to the position of the disconnector driven gear 3, the disconnector driven gear 3 does not rotate; when the first gear segment 11 of the disconnector drive gear 1 corresponds to the position of the disconnector driven gear 3, the disconnector drive gear 1 drives the disconnector driven gear 3 to rotate.

[0065] Specifically, when the first locking arc 51 of the active locking disc 5 corresponds to the second locking arc 61 of the driven locking disc 6, the driven locking disc 6 is locked and does not rotate; when the first releasing arc 52 of the active locking disc 5 corresponds to the second releasing arc 62 of the driven locking disc 6, the driven locking disc 6 rotates with the driven gear 3 of the isolating switch.

[0066] In this embodiment, the number of teeth in the first gear segment 11 of the disconnector switch driving gear 1 is twice the number of teeth in the disconnector switch driven gear 3. During the operation of the disconnector switch, the disconnector switch driven gear 3 can rotate 2 revolutions, thus reducing the force on its shaft by half. This helps to reduce stress and allows for a reduction in the size of the components.

[0067] In this embodiment, the isolating switch drive gear 1, the valve drive gear 2, and the active locking disc 5 are driven to rotate synchronously by the same splined shaft; the active locking disc 5 is located between the isolating switch drive gear 1 and the valve drive gear 2.

[0068] In this embodiment, the diameters of the second gear segment 21 and the second non-tooth segment 22 of the valve drive gear 2 are basically equal; the diameter of the first locking arc 51 of the drive locking disc 5 is greater than the diameter of the first loosening arc 52; the diameter of the first gear segment 11 of the disconnect switch drive gear 1 is greater than the diameter of the first non-tooth segment 12; and the diameter of the second locking arc 61 of the driven locking disc 6 is greater than the diameter of the second loosening arc 62.

[0069] In this embodiment, the second gear segment 21 of the valve driving gear 2 and the third gear segment 41 of the valve driven gear 4 have the same number of teeth.

[0070] In this embodiment, the driven gear 3 of the disconnect switch and the driven locking disc 6 are driven to rotate synchronously by the same splined shaft.

[0071] In this embodiment, the disconnector switch drive gear 1 is provided with a limiting pin, and the switch cabinet with disconnector switch includes a bracket, the bracket is provided with a limiting block, and the limiting block limits the limiting pin.

[0072] In this embodiment, the disconnector drive gear 1 is equipped with two limit switches. The limit switches are not shown in the figure.

[0073] In this embodiment, the switch cabinet with disconnect switch includes an input gear set 7, which includes three gear sets. Each gear set includes an input pinion 71 and an input gear 72 driven by the input pinion 71. The input gear 72 of the gear set upstream along the force transmission direction and the input pinion 71 adjacent downstream are driven by the same shaft.

[0074] In this embodiment, the switch cabinet with the isolating switch includes a valve output gear set 8, which includes a first helical gear that rotates synchronously with the valve driven gear 4 driven by the same spline shaft, a second helical gear that meshes with the first helical gear, and an involute gear that is driven by the second helical gear by the same shaft.

[0075] In this embodiment, the switch cabinet with the disconnect switch includes a disconnect switch output gear set 9, which includes a large disconnect switch output gear that rotates synchronously with the disconnect switch driven gear 3 driven by the same spline shaft, and a small disconnect switch output gear that meshes with the large disconnect switch output gear.

[0076] In this embodiment, the sequential drive principle of the switch cabinet with disconnecting switches is as follows: in the initial state ( Figure 6As shown in the top diagram, the active components, including the isolating switch drive gear 1, the active locking disc 5, and the valve drive gear 2, which are driven synchronously by the same splined shaft, are in the first position defined by one of the limit switches. At this time, the switchgear with the isolating switch is in the open state, that is, the valve is in the closed state and the isolating contact is in the separated position. When closing is required, along the first direction ( Figure 6 The active components, including the disconnector gear 1, rotate clockwise. During rotation, the valve active gear 2 changes from the locking segment 42 of the valve driven gear 4 (corresponding to the second non-tooth segment 22) to the third gear segment 41 (corresponding to the second gear segment 21). The valve active gear 2 meshes with the valve driven gear 4 and drives the valve driven gear 4 to rotate, thereby opening the valve. Simultaneously, the first non-tooth segment 12 of the disconnector gear 1 always corresponds to the disconnector driven gear 3, and the first locking arc 51 of the active locking disc 5 always corresponds to the second locking arc 61 of the driven locking disc 6. The disconnector contact does not move. After rotating approximately 90°, the valve opens, but the contact does not move. Figure 6 (As shown in the middle figure), at this time, the active component continues to rotate in the first direction. During the rotation, the second non-tooth segment 22 of the valve active gear 2 always corresponds to the locking segment 42 of the valve driven gear 4, and the valve will not move. At the same time, the first gear segment 11 of the disconnecting switch active gear 1 gradually corresponds to the disconnecting switch driven gear 3, and the first disengagement arc 52 of the active locking disc 5 gradually corresponds to the driven locking disc 6. The active locking disc 5 and the driven locking disc 6 are released from locking, and the disconnecting switch active gear 1 and the disconnecting switch driven gear 3 mesh and cause the disconnecting switch driven gear 3 to rotate. Since the number of teeth of the first gear segment 11 of the disconnecting switch active gear 1 is twice the number of teeth of the disconnecting switch driven gear 3 (the circumferential angle of the first disengagement arc 52 of the active locking disc 5 is approximately 180°), the disconnecting switch driven gear 3 will rotate two revolutions. Compared with the disconnecting switch driven gear 3 rotating only one revolution, the force is smaller. After the disconnecting switch driven gear 3 rotates two revolutions, the action of the disconnecting contact is completed, the entire closing process is completed, and the sequential drive mechanism reaches the second position defined by another limit switch. Figure 6 (As shown in the bottom diagram), at this time, the first non-tooth section 12 of the disconnector drive gear 1 corresponds to the disconnector driven gear 3, and the second non-tooth section 22 of the valve drive gear 2 corresponds to the locking section 42 of the valve driven gear 4. When it is necessary to open the circuit, the drive assembly moves along the second direction ( Figure 6 By rotating the valve counterclockwise, the isolation contacts can be separated first, and then the valve can be closed to complete the tripping.

[0077] The beneficial effects of the switch cabinet with disconnecting switch in Embodiment 1 of the present invention are as follows: the pair of incomplete gear pairs used for heavy-load output of disconnecting switch operation are split into a pair of gear pairs, namely disconnecting switch driving gear 1 and disconnecting switch driven gear 3, and a pair of locking pairs, namely driving locking disc 5 and driven locking disc 6. The disconnecting switch driven gear 3 rotates two revolutions, reducing the meshing force value of the disconnecting switch driving and driven gear pairs, thereby avoiding problems such as tooth misalignment and tooth overload caused by the disconnecting switch.

Those skilled in the art should understand that the present invention includes, but is not limited to, the content described in the above specific embodiments. Any modifications that do not depart from the functional and structural principles of the present invention will be included within the scope of the claims.
