Description

Technical Field

[0001] The invention belongs to the technical field of high-voltage switches, and in particular relates to a switch mechanism box and an isolating switch. Background Art

[0002] High-voltage disconnectors are key protection devices in power systems. They can provide necessary isolation and disconnection functions in the operation, maintenance and accident handling of power systems to ensure safe and stable operation of the system. Generally speaking, disconnectors are configured at both ends of the circuit breaker. For more complex wiring methods, disconnectors may be configured at multiple locations of the circuit breaker. In fact, the number of disconnectors is twice or even more than the number of circuit breakers. With the continuous development of the power system, the power grid has an increasing demand for disconnectors. The safe and stable operation of disconnectors is of great significance to maintaining the stability of the power system.

[0003] The isolating switch includes an operating mechanism for driving the moving contact to perform opening and closing actions and a mechanism box for installing and protecting the operating mechanism, wherein the output end of the operating mechanism passes through one side of the mechanism box and is connected to the transmission mechanism of the switch, and the mechanism box is generally installed on a corresponding foundation (such as a pillar) provided on the isolating switch body. In the prior art, a transition bracket is fixedly provided on one side wall of the mechanism box, and a mounting plate is fixedly provided on the transition bracket. The mounting plate is parallel to the side wall of one side of the box body, and a bolt through hole is provided on the mounting plate. A mounting bracket is provided on the corresponding foundation for installing the mechanism box, and a bolt through hole is also provided on the mounting bracket. The same connecting bolt passes through the bolt through holes on the mounting plate and the mounting bracket at the same time and cooperates with a nut to connect the mounting plate and the mounting bracket, thereby realizing the installation and fixation of the mechanism box.

[0004] At present, when developing isolating switches of different models and used in different sites, in addition to designing the operating mechanism, in order to match different operating mechanisms, the transition bracket and mounting plate installed on the mechanism box also need to be customized to ensure that the output end of the operating mechanism can be connected to the transmission mechanism of the switch, and the mechanism box can be installed on the isolating switch body. In other words, the existing mechanism box is difficult to be used for different isolating switches. This will increase the development investment cost, and during on-site installation, it is also necessary to select corresponding auxiliary tooling for different types of isolating switches, which is inconvenient to operate and has low installation efficiency. Summary of the invention

[0005] The purpose of the present invention is to provide a switch mechanism box to solve the technical problem of insufficient versatility of the switch mechanism box in the prior art. The purpose of the present invention is also to provide an isolating switch to solve the problems of high development cost and inconvenient operation caused by insufficient versatility of the mechanism box of the isolating switch.

[0006] To achieve the above purpose, the technical solution of the switch mechanism box provided by the present invention is:

[0007] A switch mechanism box comprises a box body and a mounting plate, wherein the mounting plate and the side wall of one side of the box body are parallel, and a distance adjusting mechanism for adjusting the distance between the two and a positioning mechanism for adjusting the position of the mounting plate in a plane parallel to the side wall are connected between the two. The distance adjusting mechanism and the positioning mechanism both comprise a guide structure and a locking structure for locking a mating piece that cooperates with the guide structure in a determined position. The guide structure of one of the distance adjusting mechanism and the positioning mechanism is fixed on the side wall, and the mating piece is fixedly connected to the guide structure of the other mechanism. The mounting plate constitutes the mating piece of the other mechanism or is fixedly connected to the mating piece. A long hole for the connecting bolt to pass through is provided on the mounting plate, and the length extension direction of the long hole is perpendicular to the guide direction of the guide structure of the positioning mechanism.

[0008] As a further improvement, the guide structure of the position adjustment mechanism includes two or more guide rails arranged at intervals, each guide rail is equipped with a matching piece, the guide rail is fixed to the side wall, and the guide structure of the distance adjustment mechanism is fixedly connected to the matching piece on the guide rail.

[0009] As a further improvement, the mating piece in the positioning mechanism that cooperates with the guide rail includes a slider equipped with a self-locking structure, the slider cooperates with the guide rail, and the self-locking structure equipped with the slider constitutes the locking structure of the positioning mechanism.

[0010] As a further improvement, the guide structure of the distance adjustment mechanism includes two or more guide posts arranged at intervals, and the matching parts in the adjustment mechanism also include transition plates connected to each slider, and each guide post is fixedly connected to the transition plate.

[0011] As a further improvement, the transition plate is an annular plate.

[0012] As a further improvement, the guide structure of the distance adjustment mechanism includes two or more guide columns arranged at intervals, the guide columns are fixedly connected to the matching parts in the adjustment mechanism, and the mounting plate is sleeved on the guide columns and constitutes a matching part that cooperates with the guide columns.

[0013] As a further improvement, the outer periphery of the guide column is provided with threads, and the locking structure of the distance adjustment mechanism includes locking nuts threadedly assembled on the guide column and respectively located on both sides of the mounting plate, and the mounting plate is clamped between the locking nuts on both sides.

[0014] As a further improvement, two mounting plates are provided, and the two mounting plates are arranged at an interval, and each mounting plate is connected to at least two guide columns.

[0015] As a further improvement, each guide rail is configured with more than two sliders, and the number of guide posts is the same as that of sliders, and they are arranged opposite to each other.

[0016] The present invention belongs to the invention creation of element change, and its beneficial effect is: in the present invention, the position and spacing of the mounting plate connected and installed with the switch body relative to the box body are adjustable. Specifically, the mounting plate and the side wall of one side of the box body are connected through the distance adjustment mechanism and the position adjustment mechanism, and the distance adjustment mechanism and the position adjustment mechanism both include a guide structure, and the guide structure stipulates the moving direction of the matching piece that cooperates with the guide. The guide structure of one of the distance adjustment mechanism and the position adjustment mechanism is fixed on the side wall, and the matching piece is fixedly connected to the guide structure of the other mechanism, and the mounting plate constitutes the matching piece of the other mechanism or is fixedly connected to the matching piece, that is, for example, when the position adjustment mechanism is connected to the side wall of the box body, the distance adjustment mechanism is directly or indirectly connected to the mounting plate, the guide structure of the distance adjustment mechanism can be guided and moved relative to the position adjustment mechanism and drive the mounting plate to move, and the mounting plate can be guided and moved relative to the distance adjustment mechanism, and under the action of the locking structure, each part can be kept in a certain position to play the role of supporting the operating mechanism. At the same time, the through hole set on the mounting plate for the connecting bolt to pass through is a long hole, and the connecting bolt can be adaptively moved to different positions in the long hole. The length extension direction of the long hole is perpendicular to the guiding direction of the guiding structure of the positioning mechanism. In general, when adjusting the spacing mechanism, the spacing between the mounting plate and the box body is changed, and when adjusting the positioning mechanism, the position of the mounting plate relative to the side wall of the box body in a plane parallel to the side wall is changed. The length direction of the long hole, the guiding direction of the positioning mechanism, and the guiding direction of the spacing mechanism together form a spatial rectangular coordinate system. When the mechanism box is actually installed, on the premise of ensuring that the output end of the operating mechanism can be smoothly connected to the transmission mechanism of the switch, the mechanism box can adjust the installation position according to different installation conditions to match the installation base of the installation mechanism box on the switch. In other words, the connecting bolts used when installing the mechanism box can be moved in the above-mentioned spatial rectangular coordinate system to ensure that the mechanism box can be smoothly installed. It can be seen from the above analysis that the switch mechanism box in the present invention can be used for switches of different models and applied in different positions.

[0017] To achieve the above object, the technical solution of the isolating switch provided by the present invention is:

[0018] A disconnector comprises an operating mechanism and a mechanism box, wherein the mechanism box comprises a box body and a mounting plate, wherein the mounting plate and the side wall of one side of the box body are parallel, and a distance adjusting mechanism for adjusting the distance between the two and a positioning mechanism for adjusting the position of the mounting plate in a plane parallel to the side wall are connected between the two. The distance adjusting mechanism and the positioning mechanism both comprise a guide structure and a locking structure for locking a matching piece that cooperates with the guide structure at a determined position. The guide structure of one of the distance adjusting mechanism and the positioning mechanism is fixed on the side wall, and the matching piece is fixedly connected to the guide structure of the other mechanism. The mounting plate constitutes the matching piece of the other mechanism or is fixedly connected to the matching piece. A long hole for a connecting bolt to pass through is provided on the mounting plate, and the length extension direction of the long hole is perpendicular to the guide direction of the guide structure of the positioning mechanism.

[0019] As a further improvement, the guide structure of the position adjustment mechanism includes two or more guide rails arranged at intervals, each guide rail is equipped with a matching piece, the guide rail is fixed to the side wall, and the guide structure of the distance adjustment mechanism is fixedly connected to the matching piece on the guide rail.

[0020] As a further improvement, the mating piece in the positioning mechanism that cooperates with the guide rail includes a slider equipped with a self-locking structure, the slider cooperates with the guide rail, and the self-locking structure equipped with the slider constitutes the locking structure of the positioning mechanism.

[0021] As a further improvement, the guide structure of the distance adjustment mechanism includes two or more guide posts arranged at intervals, and the matching parts in the adjustment mechanism also include transition plates connected to each slider, and each guide post is fixedly connected to the transition plate.

[0022] As a further improvement, the transition plate is an annular plate.

[0023] As a further improvement, the guide structure of the distance adjustment mechanism includes two or more guide columns arranged at intervals, the guide columns are fixedly connected to the matching parts in the adjustment mechanism, and the mounting plate is sleeved on the guide columns and constitutes a matching part that cooperates with the guide columns.

[0025] As a further improvement, two mounting plates are provided, and the two mounting plates are arranged at an interval, and each mounting plate is connected to at least two guide columns.

[0026] As a further improvement, each guide rail is configured with more than two sliders, and the number of guide posts is the same as that of sliders, and they are arranged opposite to each other.

[0027] The present invention belongs to the invention creation of element change, and its beneficial effect is: in the present invention, the position and distance of the mechanism box relative to the disconnector are adjustable. Specifically, for the mechanism box, the installation plate and the side wall of one side of the box body are connected through the distance adjustment mechanism and the position adjustment mechanism. The distance adjustment mechanism and the position adjustment mechanism both include a guide structure, and the guide structure stipulates the moving direction of the matching piece that cooperates with the guide. The guide structure of one of the distance adjustment mechanism and the position adjustment mechanism is fixed on the side wall, the matching piece is fixedly connected to the guide structure of the other mechanism, and the installation plate constitutes the matching piece of the other mechanism or is fixedly connected to the matching piece.

At the same time, the through hole set on the mounting plate for the connecting bolt to pass through is a long hole, and the connecting bolt can be adaptively moved to different positions in the long hole. The length extension direction of the long hole is perpendicular to the guiding direction of the guiding structure of the positioning mechanism. In general, when adjusting the spacing mechanism, the spacing between the mounting plate and the box body is changed, and when adjusting the spacing mechanism, the position of the mounting plate relative to the side wall of the box body in a plane parallel to the side wall is changed. The length direction of the long hole, the guiding direction of the positioning mechanism, and the guiding direction of the spacing mechanism together form a spatial rectangular coordinate system. When the mechanism box is actually installed, on the premise of ensuring that the output end of the operating mechanism can be smoothly connected to the transmission mechanism of the switch, the mechanism box can adjust the installation position according to different installation conditions to match the installation base of the installation mechanism box on the switch. In other words, the connecting bolts used when installing the mechanism box can move in the above-mentioned spatial rectangular coordinate system to ensure that the mechanism box can be smoothly installed. It can be seen from the above analysis that the switch mechanism box in the present invention can be universally used for disconnectors of different models and applications in different positions. Therefore, when developing disconnectors, it is not necessary to redevelop the mechanism box, which is low in cost, and this universal mechanism box is also convenient for on-site operation and installation.

[0036] In order to provide a mechanism box for a switch operating mechanism with greater versatility, the basic technical concept of the present invention is to change the connection relationship between the mounting plate of the mechanism box and the box body, so that the spacing and relative position of the mounting plate relative to the box body are adjustable, and at the same time, the through holes on the mounting plate for the connection bolts to pass through are changed to long holes, and the range of the through holes is expanded to adapt to mounting brackets in different positions. When installing the mechanism box, the spacing, relative position and other relationships between the mounting plate and the box body can be actively adjusted to ensure that the long holes on the mounting plate are adapted to the corresponding through holes on the mounting bracket for the connection bolts to pass through. The relationship between the mounting plate of this type of mechanism box and the operating mechanism and the mounting bracket on the switch is not strictly determined and cannot be changed, but the mounting plate can be actively adjusted during installation so that the mechanism box can be installed smoothly, which has strong versatility.

[0037] Based on the above concept, the present invention is further described in detail in combination with embodiments and drawings.

[0038] The specific embodiment of the switch mechanism box provided by the present invention is as follows:

[0039] The switch mechanism box provided in this embodiment is as follows Figure 1-Figure 5 As shown, it includes a box body 201 and a mounting plate 202. The mounting plate 202 is parallel to one side wall of the box body 201. The space inside the box body 201 is used to install the operating mechanism. When the switch is actually assembled, the output end 3 of the operating mechanism passes through one side of the box body 201 and is connected to the transmission mechanism of the switch body. The power output by the operating mechanism can be transmitted to the transmission mechanism of the switch body through the output end 3 to drive the switch body to open and close. The mounting plate 202 is used to install the mechanism box 2 as a whole on the switch. The switch is provided with a corresponding mounting base, such as Figure 1As shown, the switch is provided with a pillar 1, and a mounting bracket 101 is provided on the pillar 1. A connecting plate is provided at one end of the mounting bracket 101, and a through hole is provided on the connecting plate for the connecting bolt 4 to pass through. The mounting plate 202 is also provided with a through hole for the connecting bolt 4 to pass through. During installation, the connecting bolt 4 passes through the through hole on the connecting plate and the through hole on the mounting plate 202 at the same time, and a nut is used in combination to realize the connection between the mechanism box 2 and the mounting bracket 101.

[0040] The operating mechanism of switches of different models and used in different environments and the structure and position of the mounting bracket 101 are not the same. In order to make the mechanism box 2 applicable to different switches, a distance adjustment mechanism and a position adjustment mechanism are also provided between the mounting plate 202 and the side wall of the box in this embodiment, wherein the distance adjustment mechanism refers to a mechanism for adjusting the distance between the mounting plate 202 and the side wall of the box, and the position adjustment mechanism refers to a mechanism for adjusting the relative position or orientation of the mounting plate 202 and the side wall of the box in the plane parallel to the side wall. In other words, the mounting plate 202 is actually connected to one side wall of the box 201 through the distance adjustment mechanism and the position adjustment mechanism, and in order to simultaneously meet the adjustment of the distance and position of the mounting plate 202 relative to the side wall of the box, the position adjustment mechanism and the distance adjustment mechanism should be connected in series, and the series connection here should be understood as a connection or connection one by one. On the basis of the series connection of the position adjustment mechanism and the distance adjustment mechanism, in order to meet the connection between the mounting plate 202 and the side wall of the box, one of the position adjustment mechanism and the distance adjustment mechanism should be connected to the mounting plate 202, and the other should be connected to the side wall of the box. Specifically, for the position adjustment mechanism and the distance adjustment mechanism, both include a guide structure, the function of the guide structure is to determine the moving direction of the guide matching member (hereinafter referred to as the matching member) matched with the guide, and the guide direction of the guide structure of the position adjustment mechanism is parallel to the side wall of the box body 201, that is, Figure 1 , Figure 2 and Figure 6 The direction corresponding to the Z axis shown in FIG. 1 is perpendicular to the side wall of the box body 201. Figure 1 , Figure 2 and Figure 6 At the same time, the through hole 207 provided on the mounting plate 202 for the connecting bolt 4 to pass through is a long hole 207, and the length extension direction of the long hole 207 is perpendicular to the guide direction of the guide structure of the positioning mechanism, that is, Figure 1 , Figure 2 and Figure 6 The direction corresponding to the Y axis.

[0041] On the basis of the position adjustment mechanism and the distance adjustment mechanism being connected in series, in order to satisfy the connection between the mounting plate 202 and the side wall of the box body, one of the position adjustment mechanism and the distance adjustment mechanism should be connected to the mounting plate 202, and the other should be connected to the side wall of the box body. Specifically, the guide structure of one of the distance adjustment mechanism and the position adjustment mechanism should be fixed to the side wall of the box body, and the matching piece of the mechanism should be fixedly connected to the guide structure of the other mechanism, and the mounting plate should be guided and matched with the guide structure of the other mechanism. Specifically, the mounting plate can directly constitute the matching piece, or the mounting plate can be fixedly connected to the matching piece on the other mechanism. For example, the guide structure of the position adjustment mechanism is fixed to the side wall of the box body, and the guide structure of the distance adjustment mechanism is fixedly connected to the matching piece of the position adjustment mechanism, thereby realizing the adjustment of the position of the guide structure of the distance adjustment mechanism relative to the side wall of the box body. The mounting plate and the guide structure of the distance adjustment mechanism are guided and matched, thereby realizing the adjustment of the spacing of the mounting plate relative to the side wall of the box body.

[0042] The mechanism box 2 also needs to play the role of supporting the operating mechanism. For the mounting plate 202, in addition to being able to adjust the position and the distance from the side wall of the box, it also needs to be locked in a certain position. Therefore, no matter which part of the structure is the matching piece that cooperates with the guide structure of the position adjustment mechanism and the distance adjustment mechanism, the position adjustment mechanism and the distance adjustment mechanism need to be equipped with a locking structure, that is, after the mounting plate 202 is adjusted into place, the locking structure keeps the mounting plate 202 in a certain position.

[0043] When the mechanism box 2 in this embodiment is installed and used, according to the different positions of the output terminal 3 of the operating mechanism and the mounting bracket 101 of the switch, the position and spacing of the mounting plate 202 relative to the box body 201 can be changed by adjusting the positioning mechanism and the distance adjustment mechanism, while ensuring that the output terminal 3 of the operating mechanism can be reliably connected, so that the long hole 207 of the mounting plate 202 corresponds to the through hole of the connecting plate on the mounting bracket 101 in the Z-axis direction and the X-axis direction. Since the direction of the long hole 207 extends in the Y-axis direction, the long hole 207 can adapt to the through holes at different positions of the connecting plate in the Y-axis direction.

[0044] Analysis of the above installation and use process shows that the mechanism box 2 in this embodiment is suitable for different switches and has strong versatility. Therefore, when developing switches, whether it is an isolating switch, a grounding switch or a main circuit breaker, the mechanism box 2 in this embodiment can be used, and there is no need to customize the mechanism box 2 for different models, which reduces development costs and is also convenient for on-site operation and installation.

[0045] As an embodiment in which the position adjustment mechanism is connected to the side wall of the box body and the distance adjustment mechanism is connected to the mounting plate 202, Figure 2-Figure 5 As shown, the guide structure of the positioning mechanism includes two guide rails 203 fixedly connected to the side walls of the box body 201. The guide rails 203 extend in the up and down directions. Figure 2The guide rails 203 extend in the Z-axis direction, and the two guide rails 203 are arranged at intervals. Each guide rail 203 is correspondingly configured with a matching piece that cooperates with the guide rail 203 for guiding, and the guide structure of the distance adjustment mechanism is fixedly connected to the matching piece. Among them, the guide rail 203 and the side wall of the box body 201 can be connected by existing technology, such as connecting with screws or rivets, or welding. The structural strength of the guide rail 203 is higher, and the entire length of the guide rail 203 can play a guiding role, and it is also easy to install. In other embodiments, the guide structure of the positioning mechanism can also include two guide shafts (optical axes) arranged at intervals, and the two ends of the guide shaft are installed on the side wall of the box body through a base, so that the guide shaft forms a simply supported beam supported at both ends, and the matching piece that cooperates with the guide shaft for guiding can be a linear bearing sleeved on the guide shaft or a sliding block equipped with a linear bearing.

[0046] It should be noted here that, if space permits, three or more guide rails 203 may be provided that are spaced apart and arranged in parallel.

[0047] On the basis of using the guide rail 203 as the guide structure, the matching part can be configured with a slider 204 with a self-locking structure. Specifically, a slider 204 with a self-locking structure such as a wedge-shaped self-locking structure, a ratchet self-locking structure, a thread self-locking structure, etc. in the prior art can be selected. After the slider 204 is self-locked, the locking force between it and the guide rail 203 should meet the requirements of supporting the operating mechanism. The self-locking structure configured on the slider 204 itself constitutes the locking structure of the above-mentioned adjustment mechanism. In this case, there is no need to configure other locking structures, the overall parts are less, and it is further convenient for on-site installation.

[0048] Of course, in other embodiments, no matter which other form of guide structure is adopted, a separate locking structure can be added. For example, in a simple embodiment, if the guide rail 203 has a guide groove, and the matching piece is a movable block that moves along the guide groove, a through hole can be set on the side wall of the guide groove, and after the movable block is in place, a top screw is passed through the through hole to tighten the movable block and lock it with the guide rail 203. For another example, the locking structure can also be a screw-nut mechanism, in which the screw-nut mechanism is installed on the side wall of the box 201, wherein the screw or the screw is rotatably installed on the box 201, and a block is provided on the screw that is threadedly connected to it, and the block is connected to the matching piece (such as the slider 204), and when the matching piece moves up and down along the guide rail 203, the screw rotates and the block moves synchronously, and the matching piece can be directly locked after it moves into place.

[0049] like Figure 2-Figure 6As shown, the guide structure of the distance adjustment mechanism includes a guide column 206, and four guide columns 206 are provided, and the four guide columns 206 are arranged at intervals. The mounting plate 202 is sleeved on the guide column 206, that is, in addition to the long hole 207, the mounting plate 202 is also provided with a through hole adapted to the guide column 206. In this case, the mounting plate 202 is actually a matching piece for guiding and matching with the guide column 206. This solution has a simple structure, can save independent matching pieces, and is easy to install.

[0050] Of course, in other implementations, an independent matching piece may be added, such as a sliding block that is sleeved on the guide post 206 and is guided and matched with the guide post 206, and the guide plate is connected to the sliding block.

[0051] The guide structure of the distance adjustment mechanism is not limited to the above-mentioned one. In other implementations, the guide column 206 can also be replaced by the guide rail 203. In this case, it is necessary to add a matching piece that cooperates with the guide rail 203, and the mounting plate 202 is connected to the matching piece.

[0052] Considering the supporting capacity of the guide pillar 206 , in other embodiments, at least two guide pillars 206 should be provided.

[0053] Regardless of the number of guide posts 206, in a preferred embodiment, the matching parts of the positioning mechanism also include a transition plate 205, each slider is connected to the transition plate 205, and each guide post 206 is also fixedly connected to the same transition plate 205, and the specific connection method can be welding or screwing. Compared with the embodiment of directly fixing the guide post 206 to the slider, this can form a more integrated structure and improve the structural strength. More preferably, the transition plate 205 is an annular plate. Compared with an ordinary flat plate, the annular plate has a lighter weight and can reduce the load on the basis of inconvenient or even stronger bending and torsion resistance.

[0054] Specifically, the outer periphery of the guide column 206 is provided with a thread, and the locking structure of the distance adjustment mechanism includes locking nuts 208 respectively located on both sides of the mounting plate 202, the locking nuts 208 are threadedly connected to the guide column 206, and the mounting plate 202 is clamped between the locking nuts 208. The locking nuts 208 on both sides of the mounting plate 202 cooperate to jointly limit the position of the mounting plate 202 in the extension direction of the guide column 206. When the mounting plate 202 needs to be adjusted, the locking nuts 208 can be loosened. The figure shows an example of a case where only two locking nuts 208 are included, and in other embodiments, three or more nuts can be provided. In this case, in addition to the two locking nuts 208 used to directly clamp the mounting plate 202, the other nuts can play a role in preventing loosening. Of course, during the specific on-site installation, the gaskets can be increased or decreased according to the needs.

[0055] In addition, considering the cost, in this embodiment, on the basis of satisfying the connection and installation of the mechanism box 2 and the mounting bracket 101, the mounting plate 202 is composed of two independent or separate plates, each of which is provided with a long hole 207 and each of which is connected to at least two guide posts. In other embodiments, the mounting plate 202 may also include only one complete plate.

[0056] In this embodiment, each guide rail 203 is equipped with two sliders 204, the number of guide posts 206 is the same as the number of sliders 204, and the guide posts 206 and the sliders 204 are arranged opposite to each other during installation. This makes installation easier on the one hand, and there is no force arm between the guide posts 206 and the sliders 204 on the other hand, so the overall strength is higher. It is not difficult to understand that in other embodiments, according to actual installation requirements, the number of guide posts 206 and the number of sliders 204 can also be appropriately increased or decreased, and staggered installation can be performed.

[0057] It should be noted that Figure 1-Figure 6 An exemplary implementation is given in which the guide rail 203 extends vertically (Z axis) and the long hole 207 extends horizontally (Y axis), but in fact, the extension directions of the guide rail 203 and the long hole 207 can also be interchanged, that is, the guide rail 203 extends horizontally (Y axis) and the long hole 207 extends vertically (Z axis), which does not affect the normal use of the mechanism box 2.

[0058] It should also be noted that in other embodiments, the mechanism connected to the side wall of the box body may also be a distance adjustment mechanism, and the mechanism connected to the mounting plate may be a position adjustment mechanism. In this case, the mounting plate can also adjust the position and spacing relative to the side wall of the box body. Specifically, how to set the distance adjustment mechanism and the position adjustment mechanism can be determined by a person skilled in the art according to the above-given combination, and will not be described in detail here.

[0059] The specific embodiment of the isolating switch in the present invention:

[0060] The isolating switch includes an operating mechanism and a mechanism box. The mechanism box is the mechanism box described in the above switch mechanism box embodiment, which will not be described in detail here.
