The electromagnetic system drives the movable contact mechanism of the contact system to rotate through a transmission structure to close and open the contact system. In this type of switch device, the transmission relationship between the electromagnetic system and the movable contact mechanism is complex, and the armature of the electromagnetic system is set to swing multiple times, which further complicates the transmission structure between the electromagnetic system and the movable contact mechanism. In addition, due to the layout of the electromagnetic system and the contact system, the dimensions of the switch device are large in all directions, which is not convenient for use in a small space. In addition, the switch device also includes a reset member for driving the armature and yoke of the electromagnetic system. The reset member often takes up a large installation space, affecting the compactness of the overall structure of the switch device. In addition, the switch device also includes a control system, which is connected to the electromagnetic system to drive its operation.

[0049] The following embodiments are combined with the accompanying drawings to further illustrate the specific implementation of the switch device of the present invention. The switch device of the present invention is not limited to the description of the following embodiments.

[0050] like Figure 2-5As shown, the height, width, and length directions of the switch device of the present invention are respectively the same as the first direction d1, the second direction d2, and the third direction d3, and the switch device includes an electromagnetic system 3 and a switch unit s, wherein the first direction d1, the second direction d2, and the third direction d3 are perpendicular to each other in a three-dimensional space; the electromagnetic system 3 includes a magnetic generating component m and an armature 31 used in conjunction with each other, and the magnetic generating component m includes a yoke 32 and a coil assembly 33 used in conjunction with each other and fixedly assembled; the switch unit s includes at least one set of switch modules 2, the switch module 2 includes a contact system, and the contact system includes a movable contact mechanism 23 and a static contact group used in conjunction with each other, and the movable contact mechanism 23 is configured to move (for example, to move or rotate as a whole); the armature 31 is transmission-connected to the movable contact mechanism 23, driving the movable contact mechanism 23 to move and close and open with the static contact group (that is, to close and open the switch device). The coil assembly 33 generally includes a coil bobbin and an electromagnetic coil wound on the coil bobbin. This is the prior art in the field and will not be described in detail here.

[0051] Furthermore, the switch device of the present invention also includes a reset member 5; when the magnetic generating component m is energized to generate a magnetic field, the armature 31 is attracted by the yoke 32, and the armature 31 moves and is attracted together with it; after the magnetic generating component is de-energized, the magnetic field disappears, and the reset member 5 drives the armature 31 to separate from the yoke 32.

[0052] As another embodiment, the switch device of the present invention does not include a reset member 5, but instead includes two sets of magnetic generating components m, namely a first magnetic generating component and a second magnetic generating component. When the first magnetic generating component m is energized and the second magnetic generating component is de-energized, the first magnetic generating component generates a magnetic field, and the yoke 32 of the first magnetic generating component attracts the armature 31, which moves and engages with the yoke 32 of the first magnetic generating component. When the first magnetic generating component m is de-energized and the second magnetic generating component is energized, the second magnetic generating component generates a magnetic field, and the yoke 32 of the second magnetic generating component attracts the armature 31, which moves and engages with the second magnetic generating component 32. Of the first magnetic generating component and the second magnetic generating component, one is always energized and the other is de-energized, so that the armature 31 can drive the movable contact mechanism 23 to close and open with the static contact group. Furthermore, the two sets of magnetic generating components m are arranged relative to each other, and the armature 31 swings or moves as a whole between the two sets of magnetic generating components m.

[0053] like Figure 2 As shown, the switch device of the present invention also includes a control system 8, which is connected to the electromagnetic system 3 to control the operation of the electromagnetic system 3. Furthermore, the control system 8 is connected to a host computer (which can be a computer or other intelligent device for remote control, such as a mobile phone or tablet). Specifically, the control system 8 includes a control circuit board disposed within the housing 1; the coil terminals of the coil assembly 33 of the electromagnetic system 3 are connected to the control system 8.

[0054] like Figure 1 、 2 As shown in FIG5 , the switch device of the present invention further comprises a housing structure, which comprises a shell 1 , wherein the electromagnetic system 3 and the switch unit s are both accommodated in the shell 1 . Furthermore, the control system 8 is also accommodated in the shell 1 .

[0055] like Figure 2-5 As shown, the switch device of the present invention also includes an operating system, which includes an operating device and a movable contact mechanism 23 of at least one switch module 2. The operating device includes an electromagnetic system 3, and the armature 31 of the electromagnetic system 3 is transmission-connected to the movable contact mechanism 23. Furthermore, the operating device also includes a transmission structure 4, through which the armature 31 is transmission-connected to the movable contact mechanism 23 to drive its movement.

[0056] like Figure 2-6 FIG. 1 shows an embodiment of the operating system.

[0057] In the operating system of this embodiment, the movable contact mechanism 23 is rotatably arranged with its rotation axis parallel to the second direction d2. The movable contact mechanism 23 is driven by the armature 31 to rotate so as to close and open with the static contact assembly.

[0058] like Figure 3-6 As shown, the armature 31 is integrally movable along the axial direction of the coil assembly 33. The movement direction of the armature 31 is perpendicular to the second direction d2 and coincides with the axial direction of the coil assembly 33. The armature 31 reciprocates as a whole, driving the movable contact mechanism 23 to rotate reciprocally, thereby closing and opening the contact with the static contact assembly. This embodiment of the operating system, which includes the electromagnetic system 3, the transmission structure 4, and the movable contact mechanism 23, has a simple structure. The movable contact mechanism 23 is driven to rotate by the integrally movable armature 31, resulting in simple and reliable operation, which facilitates the simplification of the transmission structure between the electromagnetic system 3 and the movable contact mechanism 23.

[0059] In the operating system of this embodiment, the armature 31 is preferably arranged to move as a whole along the third direction d3. That is, the axial direction of the coil assembly 33 is aligned with the third direction d3, and the second direction d2 is perpendicular to the third direction d3. Furthermore, the movable contact mechanism 23 and the magnetic generating assembly m are arranged side by side along the third direction d3; the armature 31 moves along the third direction d3 between the movable contact mechanism 23 and the magnetic generating assembly m. That is, the projection of the operating system perpendicular to the second direction d2 and parallel to the third direction d3 is the first projection of the operating system. The movable contact mechanism 23 and the magnetic generating assembly m are respectively located at opposite ends of the first projection of the operating system. During the movement of the armature 31, the entire armature 31 is always located between the two boundaries of the first projection of the operating system in the third direction d3.

[0060] As another embodiment, the axial direction of the electromagnetic coil 33 is the same as the first direction d1, and the armature 31 is arranged to move as a whole along the first direction d1; the magnetic generating component m can be arranged side by side with the moving contact mechanism 23 along the second direction d2, or along the first direction d1.

[0061] It should be noted that the axial direction of the coil assembly 33 is perpendicular to the second direction d2, that is, on the projection of the operating system of this embodiment perpendicular to the second direction d2, the angle between the axial direction of the coil assembly 33 and the third direction d3 can be any angle (0-360°).

[0062] In the operating system of this embodiment, the relative position relationship between the electromagnetic system 3 and the moving contact mechanism 23 can be adjusted according to actual needs, so that the operating system of this embodiment can be applied to different application environments.

[0063] Specifically, such as Figure 5-6As shown, the armature 31 is a T-shaped structure and includes an armature vertical arm 31-0 and an armature horizontal arm 31-1. One end of the armature vertical arm 31-0 is connected to the middle of the armature horizontal arm 31-1 and the other end is used to be movably inserted in the middle of the coil assembly 33 along the axial direction (that is, the third direction d3) of the coil assembly 33. The armature horizontal arm 31-1 is located between the moving contact mechanism 23 and the yoke 32 in the third direction d3; the yoke 32 includes a yoke hand 32-2, and the two yoke hands 32-2 are respectively connected to the two ends of the armature horizontal arm 31-1. The two yoke hands 32-2 are arranged relative to each other along the third direction d3 (i.e., the armature cross arm 31-1 moves along the third direction d3 to engage and disengage with the yoke hand 32-2). The two yoke hands 32-2 are disposed on one axial side of the coil assembly 33 and spaced relative to each other to form a first channel. The free end of the armature vertical arm 31-0 (i.e., the end of the armature vertical arm 31-0 away from the armature cross arm 31-1) passes through the first channel and is inserted into the middle of the coil assembly 33. The armature cross arm 31-1 and the movable contact mechanism 23 are located on the same axial side of the coil assembly 33. Furthermore, the two yoke hands 32-2 are disposed relative to each other along the first direction d1, and the armature cross arm 31-1 extends along the first direction d1. The first direction d1, the second direction d2, and the third direction d3 are perpendicular to each other in three-dimensional space. Furthermore, the yoke 32 also includes a yoke back plate 32-0 and a yoke arm 32-1. The two ends of the yoke back plate 32-0 are each bent and connected to one end of a yoke arm 32-1, and the other ends of the two yoke arms 31-1 are each bent and connected to one end of a yoke hand 32-2. The other ends of the two yoke hands 32-2 are relatively spaced apart (relatively spaced apart along the first direction d1) to form a first channel. The two yoke hands 32-2 and the yoke back plate 32-0 are respectively located on both sides of the axial direction of the coil assembly 33, and the two yoke arms 32-1 are respectively located on both sides of the radial direction of the coil assembly 33; the yoke 32 is a square frame structure as a whole and is arranged around the coil assembly 33. The yoke 32 may also optionally be provided with a yoke intermediate arm (i.e., the yoke 32 may or may not be provided with the yoke intermediate arm). One end of the yoke intermediate arm is connected to the middle portion of the yoke back plate 32-0, and the other end is inserted into the middle portion of the coil assembly 33. This arm is configured to engage with the free end of the armature vertical arm 31-0, thereby improving the reliability of the engagement between the armature 31 and the yoke 32 when the armature 31 and the yoke 32 are engaged. When the yoke 32 is not provided with the yoke intermediate arm, when the armature horizontal arm 31-1 and the two yoke arms 32-2 are engaged, the free end of the armature vertical arm 31-0 can also simultaneously engage with the yoke back plate 32-0, thereby improving the reliability of the engagement between the armature 31 and the yoke 32.

[0064] It should be pointed out that the layout of the armature 31, the magnetic generating component m and the moving contact mechanism 23 is not limited to the above-mentioned method. For example, the two yoke hands 32-2 of the yoke 32 can also be arranged side by side along the second direction d2, and the extension direction of the armature cross arm 31-1 of the armature 31 is adjusted accordingly; or, the armature cross arm 31-1 of the armature 31 and the moving contact mechanism 23 can also be arranged on both sides of the axial direction of the magnetic generating component m, and the yoke back plate 32-0 and the moving contact mechanism 23 are located on the same axial side of the coil component 33.

[0065] As other embodiments, the yoke 32 and the armature 31 are both E-shaped structures, the yoke 32 includes a yoke cross plate, a yoke middle leg and a yoke side leg, the two yoke side legs are located on both sides of the yoke middle leg, and one end of the yoke side leg and the yoke middle leg are both connected to the yoke cross plate, the armature 31 includes an armature cross plate, an armature middle leg and an armature side leg, the two armature side legs are located on both sides of the yoke middle leg, and one end of the armature side leg and the armature middle leg are both connected to the armature cross plate, the yoke cross plate and the armature cross plate are respectively located on both axial sides of the coil assembly 33, the yoke middle leg and the armature middle leg are respectively inserted into the coil assembly 33 from both axial sides and along the axial direction of the coil assembly 33, the free ends of the yoke middle leg and the armature middle leg are relatively matched, the two yoke side legs are respectively located on both radial sides of the coil assembly 33, the two armature side legs are respectively located on both radial sides of the coil assembly 33, and the armature side legs are relatively matched with the free ends of the corresponding yoke side legs.

[0066] Further, such as Figure 3-4 As shown, the transmission structure 4 and the moving contact mechanism 23 are arranged side by side along the second direction d2, that is, the transmission structure 4 as a whole is arranged side by side with the switch module 2 along the second direction d2, or at least a part of the transmission structure 4 is arranged side by side with the switch module 2 along the second direction d2. In this embodiment, a part of the transmission structure 4 and the moving contact mechanism 23 are arranged side by side along the second direction d2, that is, on the projection of the operating system of this embodiment perpendicular to the second direction d2, a part of the transmission structure 4 overlaps with the moving contact mechanism 23.

[0067] like Figure 3-6 As shown, the transmission structure 4 includes a linkage member 41, one end of which is connected to the armature 31 and the other end of which is directly or indirectly connected to the movable contact mechanism 23. Furthermore, the linkage member 41 and the armature 31 are arranged to move synchronously and remain relatively stationary during movement. That is, during the movement of the linkage member 41 and the armature 31, the linkage member 41 will not move (or rotate) relative to the armature 31, or the linkage member 41 will only move (or rotate) slightly relative to the armature 31 within the range allowed by the assembly tolerance, and this slight movement (or rotation) can be ignored in the overall movement of the linkage member 41.

[0068] Furthermore, the transmission structure 4 also includes a connecting rod 42, one end of the connecting rod 42 is hinged to the linkage 41 and the other end is connected to the moving contact mechanism 23 through a linkage shaft 44, and the linkage shaft 44 is inserted in the moving contact mechanism 23 and is arranged parallel to the rotation axis of the moving contact mechanism 23. The end of the connecting rod 42 hinged to the linkage 41 is the first end of the connecting rod and the end connected to the moving contact mechanism 23 through the linkage shaft 44 is the second end of the connecting rod. During operation, when the electromagnetic system 3 drives the moving contact mechanism 23 to rotate, the first end of the connecting rod moves synchronously with the linkage 41 and the second end of the connecting rod swings around the first end of the connecting rod and drives the moving contact mechanism 23 to rotate through the linkage shaft 44. Furthermore, the connecting rod 42 is a straight connecting rod, with a connecting rod connection hole 42-10 and a connecting rod drive hole 42-11 respectively provided at each end. The connecting rod connection hole 42-10 cooperates with the linkage shaft 44, and the connecting rod drive hole 42-11 is used to be hingedly connected to the linkage member 4 (specifically, the linkage member drive portion 41-3 of the linkage member 4, which will be described below) via the connecting shaft 43. Furthermore, one end of the connecting rod 42 is a tuning fork-shaped structure, and the linkage member drive portion 41-3 of the linkage member 4 is inserted into the middle of the tuning fork-shaped structure and hinged therewith, which helps to reduce the installation space required after the linkage member 41 and the connecting rod 42 are connected, thereby ensuring a reliable connection between the two.

[0069] The transmission structure 4 includes a linkage member 41 and a connecting rod 42, and has a simple structure, a short and reliable transmission link.

[0070] As other embodiments, the transmission structure 4 is not provided with a connecting rod 42, and the linkage member 41 and the armature 31 are still arranged to move synchronously and remain relatively stationary during the movement. Instead, the linkage member 41 is directly connected to the moving contact mechanism 23 through the linkage shaft 44. Specifically: one end of the linkage member 41 connected to the armature 31 is the first end of the linkage member and the other end is the second end of the linkage member. The second end of the linkage member is connected to the moving contact mechanism 23 through the linkage shaft 44. A waist-shaped hole is provided at the second end of the linkage member, and the linkage shaft 44 is inserted into the waist-shaped hole. The waist-shaped hole includes two opposite driving sides, namely a closing driving side and a disconnecting driving side. During operation, the electromagnetic system 3 drives the moving contact mechanism 23 to rotate: the closing driving side of the waist-shaped hole presses the linkage shaft 44 to drive the moving contact mechanism 23 to rotate so that it is closed with the static contact group, and at the same time, the linkage shaft 44 slides relative to the closing driving side; the disconnecting driving side of the waist-shaped hole presses the linkage shaft 44 to drive the moving contact mechanism 23 to rotate so that it is disconnected from the static contact group, and at the same time, the linkage shaft 44 slides relative to the disconnecting driving side. Furthermore, the armature 31 and the linkage member 41 are an integrated structure.

[0071] As other embodiments, the transmission structure 4 does not have a connecting rod 42, and the linkage member 41 is directly connected to the moving contact mechanism 23 through the linkage shaft 44 and is arranged to rotate relative to the armature 31. Specifically: one end of the linkage member 41 is hinged to the armature 31 and this end is the first end of the linkage member, and the other end of the linkage member 41 is connected to the moving contact mechanism 23 through the linkage shaft 44 and this end is the second end of the linkage member; in the process of the electromagnetic system 3 driving the moving contact mechanism 23 to rotate, the first end of the linkage member moves synchronously with the armature 31, and the second end of the linkage member rotates around the first end of the linkage member and drives the moving contact mechanism 23 to rotate through the linkage shaft 44, that is, the linkage member 41 moves with the armature 31 and swings relative to the armature 31.

[0072] like Figure 3-4 As shown in Figures 6 and 7, the operating device further includes a reset member 5, which acts on the armature 31 or the linkage member 41 to drive the armature 31 and the yoke 32 apart. Specifically, when the magnetic generating component m is energized, a magnetic field is generated, causing the armature 31 and the yoke 32 to engage. When the magnetic generating component m is de-energized, the magnetic field disappears, and the reset member 5 is used to drive the armature 31 and the yoke 32 apart, thereby achieving overall reciprocating movement of the armature 31 along the third direction d3. Furthermore, the linkage member 41 moves synchronously with the armature 31 and remains relatively stationary during movement. The reset member 5 is a compression spring, one end of which is fixedly disposed (for example, this end can be fixedly disposed on the housing 1 or module housing 2-0 of the housing structure of the switch device) and the other end of which acts on the linkage member 41. Furthermore, a linkage cavity 412 is provided in the middle of the linkage 41, and the reset member 5 is arranged in the linkage cavity 412, with one end acting on the side wall of the linkage cavity 412 and the other end being fixed; the reset member 5 is realized by a compression spring and is arranged in the linkage cavity 412, which reduces the space requirement of the reset member 5, is conducive to saving assembly space, improves the structural compactness of the operating system, and reduces the space required for the operating system. Furthermore, the linkage 41 also includes a positioning platform 414 arranged on the side wall of the linkage cavity 412 (the positioning platform 414 will be described later; of course, the positioning platform 414 can also be replaced by a positioning groove, and one end of the reset member 5 is inserted into the positioning groove), and one end of the reset member 5 acting on the side wall of the linkage cavity 412 is sleeved on the positioning platform 414; the shell structure includes a shell matching portion 12-3 extending into the linkage cavity 412, and one end of the reset member 5 is fixedly set on the shell matching portion 12-3; specifically, the shell matching portion 12-3 can be a rib or baffle set in the shell 1, and the shell matching portion 12-3 can be set on the shell 1 or on the module shell 2-0. In this embodiment, the shell matching portion 12-3 is preferably set on the shell 1 and is an integrated structure with it.

[0073] Furthermore, the linkage member cavity 412 is provided between the armature 31 and the driving portion 41 - 3 . Specifically, the linkage member cavity 412 is provided between the linkage member driven portion 41 - 1 and the linkage member driving portion 41 - 3 of the linkage member 41 , which will be described in detail later.

[0074] It should be pointed out that the reset member 5 is not limited to the above-mentioned compression spring implementation method. For example, the reset member 5 is a tension spring, one end of which is connected to the linkage member 41 or the armature 31, and the other end is fixedly connected to the housing structure of the switching device; or, the reset member 5 is a torsion spring, the spiral part of which is fixedly set, one spring arm is fixedly set, and the other spring arm acts on the linkage member 41 or the armature 31; the reset member 5 can also be implemented by other existing technologies as long as it can achieve reliable reset of the armature 31, which will not be listed one by one here.

[0075] like Figure 3-6 As shown, this is an implementation of the linkage 41: the linkage 41 includes a linkage driven part 41-1, a linkage transmission part 41-2 and a linkage driving part 41-3 which are connected in sequence; the linkage driven part 41-1 is used to be connected to the armature 31 by transmission, and the linkage driving part 41-3 is used to be directly or indirectly connected to the moving contact mechanism 23 by transmission (for example, the linkage driving part 41-3 can be connected to the moving contact mechanism 23 by transmission through a connecting rod 42, specifically, the linkage driving part 41-3 is hinged to one end of the connecting rod 42 by a connecting shaft 43 and the other end of the connecting rod 42 is connected to the moving contact mechanism 23 by transmission through a linkage shaft 44; or, the linkage driving part 41-3 is directly connected to the moving contact mechanism 23 by transmission through a linkage shaft 44), and a linkage cavity 412 for accommodating the reset member 5 is provided in the middle of the linkage transmission part 412. Furthermore, the linkage member passive portion 41 includes two passive portion connecting arms 41-11, which are spaced apart from each other and have one end connected to the linkage member transmission portion 41-2. The two passive portion connecting arms 41-11 are respectively clamped on both sides of the armature 31. The fixed shaft 40 of the transmission structure 4 passes through the passive portion connecting arms 41-11 and the armature 31 to connect the passive portion connecting arms 41-11 and the armature 31 together. Furthermore, the linkage member passive portion 41-1, the linkage member transmission portion 41-2, and the linkage member driving portion 41-3 are sequentially connected end to end along the movement direction of the linkage member 41 (i.e., the movement direction of the armature 31 and the third direction d3), resulting in a simple structure and requiring little space during operation.

[0076] Furthermore, the passive part connecting arm 41 - 11 is provided with an active part connecting hole 411 , and the armature 31 is provided with an armature connecting hole 310 . The active part connecting hole 411 and the armature connecting hole 310 allow the fixed shaft 40 to pass through to connect the active part connecting part 41 - 11 and the armature 31 together. In order to achieve the synchronous movement of the armature 31 and the linkage 41 and keep them relatively still during the movement: the passive part connecting arm 41-11 and the armature 31 can be connected by multiple fixed shafts 40 arranged parallel to each other to limit the linkage 41 from rotating relative to the armature 31; or, the fixed shaft 40 is a polygonal shaft, the passive part connecting hole 411 of the passive part connecting arm 4-11 and the armature connecting hole 310 of the armature 31 are both polygonal holes matched with the polygonal shaft to limit the linkage 41 from rotating relative to the armature 31; or, the armature cross arm 31-1 of the armature 31 is provided with an armature positioning surface, and the linkage transmission part 41-2 includes a linkage positioning surface located between the two passive part connecting arms 41-11, and the armature positioning surface and the linkage positioning surface are abutted against each other to prevent the linkage 41 from rotating relative to the armature 31.

[0077] Furthermore, the linkage transmission portion 41-2 is a frame-shaped structure, with a pair of side walls connected to the linkage driven portion 41-1 and the linkage driving portion 41-3, respectively. A positioning platform 414 is provided on the inner side of the side wall of the linkage transmission portion 41-2 connected to the linkage driving portion 41-3. That is, the linkage driving portion 41-3 and the positioning platform 414 are respectively located on either side of a side wall of the linkage cavity 412. Furthermore, the free end of the driven portion connecting arm 41-11 is also adapted to be movably inserted into the middle of the coil assembly 33. The two driven portion connecting arms 41-11 preferably completely cover the armature vertical arm 31-0 of the armature 31 from both sides. Furthermore, the linkage transmission portion 41-2 is a square frame-shaped structure.

[0078] Furthermore, the linkage driving part 41 - 3 is provided with a driving part connecting hole 413 , and the driving part connecting hole 413 is used to be hinged to the connecting rod 412 through the connecting shaft 43 .

[0079] like Figure 2 and 8As shown, the movable contact mechanism 23 includes a movable contact 23-1 and a rotatably mounted contact support 23-2. The axis of rotation of the contact support 23-2 is aligned with the second direction d2, and the movable contact 23-1 is mounted on the contact support 23-2. Furthermore, the contact support 23-2 is provided with a movable contact hole 23-20. The movable contact hole 23-20 is radially disposed on one side of the rotation axis of the contact support 23-2. A linkage shaft 44 is inserted into the movable contact hole 23-20 to drive the rotation thereof. Furthermore, the moving contact mechanism 23 also includes a contact spring 23-3, and the two ends of the contact spring 23 are respectively connected to the moving contact 23-1 and the contact support 23-2; the contact spring 23-3 enables the moving contact 23-1 to establish a first limit fit with the contact support 23-2, thereby driving the moving contact 23-2 to rotate synchronously with it during the rotation process of the contact support 23-2 and closing and disconnecting with the static contact group; when the moving contact 23-1 and the static contact group are in a closed state and a short-circuit current flows through the contact system, the moving contact 23-1 will rotate relative to the contact support 23-2 and disconnect from the static contact group, and the contact spring 23-3 will lock the moving contact 23-1 in a temporary disconnection position to prevent the moving contact 23-1 and the static contact group from closing again. Furthermore, when the moving contact 23-1 is in the temporary disconnecting position, the contact spring 23-3 enables the moving contact 23-1 to establish a second limiting fit with the parking structure. The parking structure is performed by the contact support 23-2 or the shell structure of the switch device. In this embodiment, the parking structure is preferably implemented by the buffer blocking portion 25 (to be described later). Specifically, in order to realize the above-mentioned function of the contact spring 23-3, the connection relationship between the moving contact 23-1, the contact support 23-2 and the contact spring 23-3 can be realized by existing technology. For example: one end of the contact spring 23-3 is connected to the moving contact 23-1 and the other end is connected to the contact support 23-2; in a plane perpendicular to the rotation axis of the moving contact 23-1 and coinciding with the axis of the contact spring 23-3: when the moving contact 23-1 and the contact support 23-2 are in the first limiting fit state, the contact spring 23-3 The axis of the contact spring 23-3 is located on one side of the rotation axis of the moving contact 23-1, and the contact spring 23-3 makes the moving contact 23-1 tend to rotate in the first rotation direction relative to the contact support 23-2; when the moving contact 23-1 is in the temporary disconnecting position, the axis of the contact spring 23-3 is located on the other side of the rotation axis of the moving contact 23-1, and the force of the contact spring 23-3 makes the moving contact 23-1 tend to rotate in the second rotation direction relative to the contact support 23-2, and the second rotation direction is opposite to the first rotation direction.

[0080] Furthermore, the contact support 23-2 is further provided with a contact coupling hole, and the contact receiving hole 23-20 and the contact coupling hole are arranged along the rotation direction of the contact support 23-2 and around the rotation axis of the contact support 23-2. When the operating system includes multiple moving contact mechanisms 23, a coupling shaft sequentially passes through the contact coupling holes of each moving contact mechanism 23, thereby ensuring synchronous rotation of each moving contact mechanism 23. Furthermore, the axis of the contact receiving hole 23-20, the axis of the contact coupling hole, and the rotation axis of the contact support 23-2 are coplanar, and within this plane, the axis of the contact receiving hole 23-20 and the axis of the contact coupling hole are respectively located on either side of the rotation axis of the contact support 23-2.

[0081] like Figure 2 、 5 7-8 shows an embodiment of the switch module 2, which is used in conjunction with the operating system.

[0082] In the switch module 2 of this embodiment: the static contact group includes a first static contact 21 and a second static contact 22 arranged around the moving contact mechanism 23 along the rotation direction of the moving contact mechanism 23; in the moving contact mechanism 23, the moving contact 23-1 includes a moving contact bridge 23-10 and two moving contacts arranged at both ends of the moving contact bridge 23-10, and the moving contact mechanism 23 rotates to make the two moving contacts close and disconnect with the first static contact 21 and the second static contact 22 respectively (specifically, the moving contact mechanism 23 rotates to make the two moving contacts close and disconnect with the first static contact 21c of the first static contact 21 and the second static contact 22c of the second static contact 22 respectively).

[0083] like Figure 2 and 8As shown, the first static contact 21 includes a first wiring portion 21-2; the second static contact 22 includes a second bearing portion 22-1, a second transition portion 22-3, a second connecting portion 22-2 arranged relative to the second bearing portion 22-1, a sampling portion 22-4 and a second wiring portion 22-0 connected in sequence, the second bearing portion 22-1 is provided with a second static contact 22c, and the second bearing portion 22-1, the second transition portion 22-3 and the second connecting portion 22-2 are generally U-shaped structures; the first wiring portion 21-2 and the second wiring portion 21-0 are respectively used to electrically connect with two groups of external wires (one group of external wires is used to carry the current flowing into the switch module 2, and the other group of external wires is used to carry the current flowing out of the switch module 2), and the sides of the two for contacting the external wires face the same direction, which is convenient for the operator to connect the wires and convenient for the installation layout of the switch module 2. Furthermore, the first static contact 21 has an overall U-shaped structure and includes a first bearing portion 21-1 and a first transition portion 21-3. The first bearing portion 21-1, the first transition portion 21-3, and the first connecting portion 21-2 are sequentially connected, and the first bearing portion 21-1 and the first connecting portion 21-2 are spaced apart from each other. Furthermore, the plane on which the first connecting portion 21-2 and the second connecting portion 22-1 lie is parallel to the rotation axis of the moving contact mechanism 23 and parallel to each other; the plane on which the first bearing portion 21-1 and the second bearing portion 22-1 lie is parallel to the rotation axis of the moving contact mechanism 23 and parallel to each other. Furthermore, the end of the first bearing portion 21-1 away from the first transition portion 21-3 is inclined toward the side away from the first wiring portion 22-1 relative to the end of the first bearing portion 21-1 connected to the first transition portion 21-3; the end of the second bearing portion 22-1 away from the second transition portion 22-3 is inclined toward the side away from the second connection portion 22-2 relative to the end of the second bearing portion 22-1 connected to the second transition portion 22-3.

[0084] like Figure 2 and 8 As shown, the first static contact 21 and the second static contact 22 are arranged side by side and spaced apart along the first direction d1, and the first static contact 21 is offset toward the second static contact 22 in the third direction d3. That is, a first plane and a second plane are defined, the first plane is parallel to the first direction d1, the second plane is parallel to the third direction d3, and the intersection line of the first plane and the second plane coincides with the rotation axis of the moving contact mechanism 23, and the first static contact 21 and the second static contact 22 are located on both sides of the first plane and on both sides of the second plane.

[0085] like Figure 2As shown, the contact system of the switch module 2 further includes a sampling element 7 disposed on the sampling portion 24. The sampling element 7 is a Hall sensor or a shunt that facilitates sampling of the current flowing through the contact system of the switch module 2 for real-time monitoring. Furthermore, the sampling element 7 is connected to a control system 8. The control system 8 can directly control the electromagnetic system 3 based on the current signal collected by the sampling element 7, or the control system 8 can transmit the current signal collected by the sampling element 7 to a host computer, which then controls the electromagnetic system 3 based on the current signal.

[0086] As another embodiment, the sampling component 7 is not connected to the control system 8, and the switch device is provided with a signal interface, and the sampling component 7 is connected to an external device (such as a host computer) via the signal interface.

[0087] Furthermore, the sampling portion 22 - 4 and the second wiring portion 22 - 0 are located on one side of the second bearing portion 22 - 1 in the third direction d3 and the first static contact 21 is located on the other side of the second bearing portion 22 - 1 in the third direction d3, which facilitates the installation of the sampling member 7 .

[0088] Furthermore, the second connecting portion 22-2, the sampling portion 22-4 and the second wiring portion 22-0 are of a straight plate structure as a whole; the second bearing portion 22-1, the second transition portion 22-3 and the second connecting portion 22-3 form a U-shaped portion, and the sampling portion 22-4 and the second wiring portion 22-0 protrude on one side of the U-shaped portion in the opening direction of the U-shaped portion, which is beneficial for controlling the installation space required for the second static contact 22 and facilitating the arrangement of the sampling member 7 on the sampling portion 22-4; further, the first static contact 21 is of a U-shaped structure as a whole, which makes the overall structure of the static contact group simple and occupies less space.

[0089] Furthermore, the first wiring portion 21 - 2 , the first bearing portion 21 - 1 , the second bearing portion 22 - 1 , and the second connecting portion 22 - 2 are sequentially arranged along the first direction d1 .

[0090] like Figure 2 and 8As shown, the switch module 2 also includes two groups of arc extinguishing systems, which are used to extinguish the arc generated by the opening and closing of the moving contact mechanism 23 and the static contact group. Each group of arc extinguishing systems includes an arc extinguishing chamber 24. The arc extinguishing chamber 24 includes a plurality of arc extinguishing grids arranged side by side and at intervals. The arc inlet and the exhaust port of the arc extinguishing chamber 24 are arranged relative to each other along the third direction d3, and the two ends of each arc extinguishing grid extend into the arc inlet and the exhaust port of the arc extinguishing chamber 24 respectively. The two groups of arc extinguishing chambers 24 are respectively arranged on the radial sides of the moving contact mechanism 23 and are respectively the first arc extinguishing chamber and the second arc extinguishing chamber. The first static contact 21, the first arc extinguishing chamber, the second static contact 22 and the second arc extinguishing chamber are arranged around the moving contact mechanism 23 along the rotation direction of the moving contact mechanism 23. The first arc extinguishing chamber is used in conjunction with the first static contact 21 and one end of the moving contact 23-1, and the second arc extinguishing chamber is used in conjunction with the second static contact 22 and the other end of the moving contact 23-1. Furthermore, in the arc extinguishing chamber 24 , the arc extinguishing grids are arranged side by side and spaced apart along the first direction d1 .

[0091] Furthermore, each set of the arc extinguishing systems also includes a contact arc-striking structure, which is used to guide the arc generated by the opening and closing of the moving contact mechanism 23 and the static contact group into the arc-extinguishing chamber 24. The contact arc-striking structure cooperates one-to-one with the arc-extinguishing chamber 24 and includes a static arc-striking member that cooperates with the static contact group and a dynamic arc-striking portion 23-11 that cooperates with the moving contact 23-1. The static arc-striking member and the dynamic arc-striking portion 23-11 are opposite to each other to form an arc-striking channel. One end of the arc-striking channel cooperates with the static contact group and the dynamic contact 23-1, and the other end cooperates with the arc entrance of the arc-extinguishing chamber 24. Furthermore, the arc-striking channel is a trumpet-shaped arc-striking channel, with the small end of the arc-striking channel cooperating with the static contact group and the dynamic contact 23-1, and the large end of the arc-striking channel cooperating with the arc entrance of the arc-extinguishing chamber 24.

[0092] Specifically, the static arc-striking component that cooperates with the first static contact 21 is the first static arc-striking plate 21i, and the static arc-striking component that cooperates with the second static contact 22 is the second static arc-striking plate 22i. One end of the first static arc-striking plate 21i is arranged on the first bearing portion 21-1 and the other end extends toward the first arc extinguishing chamber. One end of the second static arc-striking plate 22i is arranged on the second bearing portion 22-1 and the other end is used to extend toward the second arc extinguishing chamber. A moving arc-striking portion 23-11 is provided at each end of the moving contact 23-1. The free ends of the two moving arc-striking portions 23-11 extend toward the first arc extinguishing chamber and the second arc extinguishing chamber respectively and cooperate with the first static arc-striking plate 21i and the second static arc-striking plate 22i respectively. Furthermore, the two ends of the first static arc-striking plate 21i are respectively a first inner end and a first outer end, the first inner end is arranged on the first bearing portion 21-1 and contacts the side edge of the first static contact 21c, and the first outer end extends to one side of the first arc-extinguishing chamber and is arranged side by side with the arc-extinguishing grid of the first arc-extinguishing chamber; the two ends of the second static arc-striking plate 22i are respectively a second inner end and a second outer end, the second inner end is arranged on the second bearing portion 22-1 and contacts the side edge of the second static contact 22c, and the second outer end extends to one side of the second arc-extinguishing chamber. side and arranged side by side with the arc extinguishing grid of the second arc extinguishing chamber; the moving contact 23-1 includes a moving contact bridge 23-10, and a moving arc-striking portion 23-11 is provided at each end of the moving contact bridge 23-10. The moving contact 23-1 and the moving arc-striking portion 23-11 are preferably an integrated structure, and the moving contact 23-1 and the moving arc-striking portion 23-11 are arranged to move synchronously. The two moving contacts of the moving contact bridge 23-10 are respectively used in conjunction with the first static contact 21c of the first static contact 21 and the second static contact 22c of the second static contact 22. Furthermore, the moving arc-striking portion 23-11 is horn-shaped, and the two moving arc-striking portions 23-11 are respectively a first arc-striking portion cooperating with the first static arc-striking plate 21i and a second arc-striking portion cooperating with the second static arc-striking plate 22i; when the moving contact 23-1 is in the disconnected position, a trumpet-shaped first arc-striking path is formed between the first arc-striking portion and the first static arc-striking plate 21i, and the large mouth end of the first arc-striking path is relatively matched with the arc entrance of the first arc extinguishing chamber, and a trumpet-shaped second arc-striking path is formed between the second arc-striking portion and the second static arc-striking plate 22i, and the large mouth end of the second arc-striking path is relatively matched with the arc entrance of the second arc extinguishing chamber.

[0093] As another embodiment, the moving arc-striking portion 23-11 can also be fixedly set, for example, fixedly set on the module shell 2-0. After the moving contact 23-1 is disconnected from the static contact group, one end of the moving arc-striking portion 23-11 is opposite to the moving contact 23-1 along the third direction d3 to strike an arc.

[0094] Furthermore, the first arc extinguishing chamber, the moving contact mechanism 23 and the second arc extinguishing chamber are sequentially arranged along the third direction d3.

[0095] As another embodiment, the static contact group may also include only one static contact, and one end of the moving contact 23-1 of the moving contact mechanism 23 is closed and disconnected with the static contact. Accordingly, the switch module 2 is only provided with one set of arc extinguishing systems for use with the static contact and the moving contact 23-1.

[0096] like Figure 5 、 7 As shown in Figure 8, the switch module 2 also includes a module housing 2-0, in which the contact system and arc extinguishing system are both arranged. Furthermore, the module housing 2-0 includes module half-shells 2-00 that are relatively assembled together along the axis of the rotating shaft of the moving contact mechanism 23. In other words, the two module half-shells 2-00 are relatively assembled together along the second direction d2.

[0097] Furthermore, the module housing 2-0 also includes a module housing guide hole 2-01 provided on its side wall. The linkage shaft 44 of the transmission structure 4 passes through the module housing guide hole 2-01 and is transmission-connected to the movable contact mechanism 23. Furthermore, the shape of the module housing guide hole 2-01 is adapted to the movement trajectory of the linkage shaft 44. The module housing guide hole 2-01 is preferably an arc-shaped hole with its center located on the rotation axis of the movable contact mechanism 23, thereby improving the transmission reliability between the linkage shaft 44 and the movable contact mechanism 23.

[0098] Furthermore, the module housing 2-0 also includes arc-extinguishing chamber exhaust windows 2-02 disposed on its side walls. Two sets of arc-extinguishing chamber exhaust windows 2-02 are disposed on a pair of side walls of the module housing 2-0, respectively cooperating with the exhaust ports of the first arc-extinguishing chamber and the second arc-extinguishing chamber (the exhaust port of the arc-extinguishing chamber 24 is disposed opposite the arc inlet), respectively connecting the first arc-extinguishing chamber and the second arc-extinguishing chamber to the external environment. Specifically, in the module housing 2-0, the arc-extinguishing chamber exhaust window 2-02 cooperating with the first arc-extinguishing chamber is the first arc-extinguishing chamber exhaust window, and the arc-extinguishing chamber exhaust window 2-02 cooperating with the second arc-extinguishing chamber is the second arc-extinguishing chamber exhaust window.

[0099] Furthermore, the switch module 2 also includes a magnetic arc-guiding structure, which includes a permanent magnet 26 and a magnetic conductive part 27. The two groups of magnetic arc-guiding structures are respectively coordinated with the two groups of arc extinguishing chambers 24; in each group of the magnetic arc-guiding structures, the two permanent magnets 26 are relatively arranged on both sides of the corresponding arc extinguishing chamber 24 along the axial direction of the rotating shaft of the moving contact mechanism 23 (that is, the second direction d), and the polarities of the two poles of the two permanent magnets 26 are opposite. The magnetic conductive part 27 includes two relatively arranged magnetic conductive side plates 27-1 and a magnetic conductive part connecting plate 27-2 connecting the two magnetic conductive side plates 27-1. The two magnetic conductive side plates 27-1 are respectively arranged on both sides of the two permanent magnets 26, that is, in the second direction d2, the two permanent magnets 26 are located between the two magnetic conductive side plates 27-1; the magnetic arc-guiding structure is conducive to improving the efficiency of the arc entering the arc extinguishing chamber 24, thereby improving the arc extinguishing ability and breaking performance of the switch module 2. Furthermore, the permanent magnets 26 and magnetic conductive members 27 are both disposed outside the module housing 2-0, that is, a side wall of the module housing 2-0 is disposed between the permanent magnets 26 and the corresponding arc-extinguishing chambers 24. Furthermore, a recessed structure for accommodating the permanent magnets 26 and the magnetic conductive side plates 27-1 is provided on the outer surface of the module housing 2-0, thereby improving the compactness of the switch module 2 and reducing the required installation space.

[0100] Furthermore, the switch module 2 also includes a buffer block 25. When a short-circuit current flows through the contact system, the moving contact 23-1 is repelled and rotates relative to the contact support 23-2 until the moving contact 23-1 hits the buffer block 25 and rests on it, placing the moving contact 23-1 in a temporary disconnected position. In subsequent processes, when the contact support 23-2 rotates toward the disconnected position (operated by an operator or automatically), the moving contact 23-1 is blocked by the buffer block 25 and reset relative to the contact support 23-2. Furthermore, the switch module 2 includes two buffer blocks 25, each of which engages with both ends of the moving contact 23-1. The buffer blocks 25 and the module housing 2-0 are integral structures. Alternatively, the buffer blocks 25 and the module housing 2-0 are separate structures, with the buffer blocks 25 fixed to the module housing 2-0.

[0101] like Figure 3-5As shown, when the operating device of the operating system and the switch module 2 are assembled, the magnetic generating component m of the electromagnetic system 3 and the switch module 2 are preferably arranged side by side along the third direction d3, the axial direction of the coil assembly 33 of the magnetic generating component m is the same as the third direction d3, the transmission structure 4 and the switch module 2 are arranged side by side along the second direction d2, and the armature 31 is arranged to move as a whole along the third direction d3. As other embodiments, the magnetic generating component m and the switch module 2 are arranged side by side along the first direction d1; alternatively, the electromagnetic system 3 and the switch module 2 are arranged side by side along the second direction d2. The layout of the switch module 2, the electromagnetic system 3, and the transmission structure 4 can be adjusted as needed, is reasonable and compact, and the dimensions of the switch device in various directions can be selectively optimized to enable its use in a smaller space and meet the requirements of different installation spaces.

[0102] Furthermore, the armature 31 and the transmission structure 4 are located between the two ends where the distance between the magnetic generating component m and the switch module 2 is the largest in the third direction d3, and "the two ends where the distance between the magnetic generating component m and the switch module 2 is the largest" refers to the end of the magnetic generating component m away from the switch module 2 in the third direction d3 and the end of the switch module 2 away from the magnetic generating component m in the third direction d3; in other words, on the projection of the operating device and the switch module 2 perpendicular to the second direction d2 (that is, the axial direction of the rotating shaft of the moving contact mechanism 23), the switch module 2 and the magnetic generating component m are respectively located at the two ends of the projection, and when the armature 31 moves, it will not exceed the two boundaries of the projection in the third direction d3.

[0103] Furthermore, the first static contact 21 is arranged close to the magnetic generating component m relative to the second static contact 22 in the third direction d3.

[0104] Furthermore, the second arc extinguishing chamber, the moving contact mechanism 23, the first arc extinguishing chamber and the magnetic generating component m are sequentially arranged along the third direction d3.

[0105] like Figure 1-4 FIG. 1 shows an embodiment of a switch device according to the present invention. The switch device includes the above-mentioned operating system and a switch module 2 .

[0106] In the switch device of this embodiment, the switch unit s includes at least two (i.e., two or more) switch modules 2, each of which is arranged side by side along a second direction d2. The movable contact mechanism 23 of each switch module 2 is coaxially rotatable, with the rotation axis parallel to the second direction d2. The coil assembly 33 of the electromagnetic system 3 is axially perpendicular to the second direction d2, and the armature 31 is integrally movable along the axial direction of the coil assembly 33. In the switch device of this embodiment, the electromagnetic system drives the movable contact mechanism to rotate via the integrally movable armature, resulting in simple and reliable operation.

[0107] In the switch device of this embodiment, the electromagnetic system 3 and the switch unit s are preferably arranged sequentially along the third direction d3. The magnetic generating assembly m and the switch unit s are arranged side by side along the third direction d3. The axial direction of the coil assembly 33 of the electromagnetic system 3 is aligned with the third direction d3. The armature 31 is preferably arranged to be movable as a whole along the third direction d3. The layout of the switch modules and the electromagnetic system of the switch device of this embodiment can be adjusted as needed, ensuring a reasonable and compact design. The dimensions of the switch device in various directions can be selectively optimized, enabling its use in smaller spaces and meeting the requirements of various installation spaces.

[0108] Furthermore, the magnetic generating component m and the switch unit s are respectively arranged at the two ends of the switching device in the third direction d3; the armature 31 moves between the two ends of the switching device along the third direction d3, that is, when the armature 31 moves, any part of the armature 31 will not exceed the magnetic generating component m and the switch unit s in the third direction d3; in other words, on the projection of the switching device of this embodiment perpendicular to the second direction d2, the magnetic generating component m and the switch unit s are respectively located at the two ends of the projection, and when the armature 31 moves, it will not exceed the two boundaries of the projection in the third direction d3.

[0109] As another embodiment, the magnetic generating component m and the switch unit s are arranged side by side along the first direction d1.

[0110] As another embodiment, the electromagnetic system 3 and the switch module 2 are arranged side by side along the second direction d2.

[0111] like Figure 3 and 4 As shown, the switch device of this embodiment includes at least one set of transmission structures 4, and the transmission structures 4 and each switch module 2 are arranged side by side along the second direction d2.

[0112] Furthermore, the switch device of this embodiment includes at least one switch module group t, each switch module group t including two switch modules 2 arranged side by side along a second direction d2. A transmission structure 4 is provided between the two switch modules 2 of at least one switch module group t. It should be noted that in the switch device of this embodiment, any two adjacent switch modules 2 constitute a switch module group t, and the number of switch module groups t = the number of switch modules 2 - 1. For example, a switch device having two switch modules 2 has one switch module group t; a switch device having three switch modules 2 has two switch module groups t, and so on. Of course, in the switch device of this embodiment, it is permissible to provide a transmission structure 4 between the two switch modules 2 of each switch module group t, but this will increase the structural complexity and production cost of the switch device. Furthermore, a transmission space 1-320 is provided between the two switch modules 2 of at least one switch module group t, and the transmission structure 4 is provided within the corresponding transmission space 1-320.

[0113] Specifically, in the switching device of this embodiment, the switch unit s includes two groups of switch modules 2 and a group of transmission structures 4, and the transmission structure 4 is located between the two groups of switch modules 2 in the second direction d2; that is, a transmission space 1-320 is provided between the two groups of switch modules 2, and the transmission structure 4 is accommodated in the transmission space 1-320.

The switch unit s and the electromagnetic system 3 are located at one end of the projection, and the control system 8 is located at the other end of the projection. The above-described layout of the control system 8, the electromagnetic system 3, and the switch unit s makes the wiring layout of the control system 8, the electromagnetic system 3, and the switch unit s simpler and more convenient. The layout of the switch unit, the electromagnetic system, and the control system is reasonable, occupies a small space, and improves the integrity of the switch device, facilitating installation and use.

[0115] As another embodiment, the control system 8 and the switch unit s are arranged side by side along the first direction d1. Furthermore, the magnetic generating component m is located on one side of the switch unit s and the control system 8 in the third direction d3. In other words, in a projection of the switch device of this embodiment perpendicular to the first direction d1, the switch unit s and the control system 8 overlap and are located at one end of the projection, while the magnetic generating component m is located at the other end of the projection.

[0116] like Figure 1-2 As shown, the operating device, switch unit s, and control system 8 are all arranged within a housing 1. Furthermore, the housing 1 includes a base 11 and a cover 12 that are relatively assembled together along a first direction d1.

[0117] Furthermore, the housing structure of the switch device of this embodiment also includes a module shell 2 - 0 of each switch module 2 .

[0118] As another embodiment, each switch module 2 may not be provided with a module shell 2 - 0 , but a partition plate for separating each switch module 2 may be provided in the outer shell 1 , and each partition plate and the outer shell 1 may be an integral structure or a split structure.

[0119] Furthermore, the shell 1 also includes a shell exhaust window arranged on its side wall, and the shell exhaust window includes a first shell exhaust window 12-1 and a second shell exhaust window 12-2.

[0120] Furthermore, the first exhaust window 12-1 of the shell is arranged on the side wall of the shell 1 opposite to the switch module 2 along the third direction d3 and away from the electromagnetic system 3; the second exhaust window 12-2 of the shell is arranged on the side wall of the shell 1 opposite to the switch module 2 along the first direction d1 and away from the control system 8; the layout of the first exhaust window and the second exhaust window of the shell is more convenient for the layout of the electromagnetic system and the switch module of the switching device.

[0121] As another embodiment, the first and second vent windows 12-1, 12-2 are respectively disposed on a pair of side walls of the housing 1 in the third direction d3. That is, the first vent window 12-1 is disposed on the side wall of the housing 1 that is opposite the switch module 2 and away from the electromagnetic system 3 along the third direction d3, and the second vent window 12-2 is disposed on the side wall of the housing 1 that is opposite the electromagnetic system 3 and away from the switch module 2 along the third direction d3. It should be noted that the positions of the first and second vent windows 12-1, 12-2 are adjusted based on the layout of the electromagnetic system 3 and the switch module 2.

[0122] Furthermore, the switchgear of this embodiment further includes a sparging plate 6. Gas exhausted from the first and second exhaust windows of the arc extinguishing chamber of the switch module 2 passes through the corresponding sparging plate 6 and then exits the switchgear through the first and second exhaust windows of the outer casing 12-1 and 12-2. Furthermore, the sparging plate 6 is disposed between the corresponding outer casing exhaust window and the arc extinguishing chamber exhaust window 2-02; alternatively, the sparging plate 6 is disposed within the corresponding arc extinguishing chamber exhaust window 2-02; alternatively, the sparging plate 6 is disposed within the corresponding outer casing exhaust window.

[0123] Furthermore, the first housing exhaust vent 12-1 is disposed on a first side wall of the housing 1. The first housing side wall is disposed opposite the switch unit s along a third direction d3 and is positioned away from the electromagnetic system 3 relative to the switch unit s. That is, the first housing side wall, the switch unit s, and the electromagnetic system 3 are sequentially disposed along the third direction d3. The second housing exhaust vent 12-2 is disposed on a second side wall of the housing 1. The second housing side wall is disposed opposite the switch unit s along a first direction d2 and is positioned away from the control system 8 relative to the switch unit s. That is, the second housing side wall, the switch unit s, and the control system 8 are sequentially disposed along the first direction d1. The first and second housing side walls are connected by a bend at one end.

[0124] like Figure 2 As shown, the housing 1 includes a first space 1-31 arranged therein for accommodating a magnetic generating component m of the electromagnetic system 3, a second space 1-32 for accommodating a switch module 2 driven by the electromagnetic system 3 to be closed and opened, and a third space 1-33 for accommodating a control system 8 connected at least to the electromagnetic system 3; the "control system 8 connected at least to the electromagnetic system 3" means that the control system 8 is only connected to the electromagnetic system 3, or the control system 8 is connected to the electromagnetic system 3 and is also connected to other structures of the switch device (such as the sampling component 7); the first space 1-31 and the second space 1-32 are arranged side by side along the third direction d3, and the second space 1-32 and the third space 1-33 are arranged side by side along the first direction d1.

[0125] Furthermore, the first space 1-31, the second space 1-32 and the third space 1-33 are arranged side by side along the first direction d1; that is, on the projection of the housing 1 perpendicular to the second direction d2, the first space 1-31 and the second space 1-32 are located at one end of the projection, and the third space 1-33 is located at the other end of the projection. The layout of the first space, the second space and the third space is reasonable and compact, which is conducive to reducing the overall specifications and dimensions of the switch device. Specifically, the first space 1-31 and the second space 1-32 are completely or partially arranged in the upper cover 12, and the third space 1-33 is completely arranged in the base 11; on the projection of the housing 1 perpendicular to the first direction d1, the first space 1-31 overlaps with one end of the third space 1-33, and the second space 1-32 overlaps with the other end of the third space 1-33.

[0126] As other embodiments, the first space 1-31 and the third space 1-33 are arranged side by side with the first space 1-31 along the third direction d3; that is, on the projection of the shell 1 perpendicular to the first direction d1, the second space 1-32 and the third space 1-33 overlap and are located at one end of the projection, and the first space 1-31 is located at the other end of the projection; on the projection of the shell 1 perpendicular to the second direction d2, the second space 1-32 and the third space 1-33 are arranged side by side along the first direction d1 and are located at one end of the projection, and the first space 1-31 is located at the other end of the projection. Specifically, the first space 1-31 extends into the base 11 and the upper cover 12 at both ends in the first direction d1; the second space 1-32 is partially or completely arranged in the upper cover 12; the third space 1-33 is arranged in the base 11; on the projection of the shell 1 perpendicular to the second direction d2, one end of the first space 1-31 is opposite to the second space 1-32 along the third direction d3 and the other end is opposite to the third space 1-33 along the third direction d3.

[0127] Furthermore, the module shells 2-0 are arranged side by side in the second space 1-32 along the second direction d2.

[0128] Furthermore, the second space 1-32 also includes at least one transmission space 1-320, which is arranged between two adjacent module shells 2-0 and is used to accommodate a transmission structure 4 that is respectively connected to the electromagnetic system 3 and the moving contact mechanism 23 of the switch module 2.

[0129] Furthermore, the module housing 2-0 and the base 11 mate relative to each other along the first direction d1 to enclose a third space 1-33, ensuring insulation between the phases of the switchgear while effectively isolating high and low voltages. Furthermore, the housing structure includes an isolation plate disposed between the second space 1-32 and the third space 1-33, separating the switch module 2 disposed in the second space 1-32 from the control system 8 disposed in the third space 1-33. This isolation plate further improves insulation performance within the switchgear. Furthermore, the isolation plate is detachably assembled with the base 11.
