Description

Technical Field

[0001] This application relates to the technical field of electrical equipment, and more particularly, to an automatic transfer switch electrical appliance and a power supply system. Background Art

[0002] An automatic transfer switch electrical appliance is a commonly used emergency power supply device that can transfer the load circuit from one power source to another in an emergency to achieve emergency power supply.

[0003] In the prior art, an automatic transfer switch electrical appliance usually has a mechanical interlock structure and an electrical interlock structure. During the specific conversion, the opening and closing actions are driven by a motor. At this time, the opening and closing speeds of the product only depend on the conversion speed of the driving motor. In this case, the opening and closing speeds of the product can usually only be maintained between 0.8 and 1 second. The contact making and breaking speeds are relatively slow, which easily leads to equipment shutdown and restart, and also easily damages the electrical equipment.

[0004] Therefore, there is an urgent need to provide an automatic transfer switch electrical appliance that can improve the opening and closing speeds of the contacts during emergency power supply, thereby protecting the product, improving the electrical life of the product, and the service life of the electrical equipment. Summary of the Utility Model

[0005] The purpose of this application is to provide an automatic transfer switch electrical appliance and a power supply system. The automatic transfer switch electrical appliance can improve the fast opening and closing ability of the contacts during conversion, thereby improving the making and breaking ability of the product, and the electrical life of the product and the service life of the electrical equipment.

[0006] To achieve the above purpose, according to the first aspect of this application, an embodiment of this application provides an automatic transfer switch electrical appliance. The automatic transfer switch electrical appliance includes a driving module, a conversion module, and at least one switch body connected in sequence. The driving module can drive the conversion module. The switch body includes two contact assemblies. The conversion module can respectively convert the working states of the corresponding contact assemblies. The conversion module includes two movable members and two energy storage members. The two movable members are respectively detachably connected to the driving module. The driving module can selectively drive the movable members to move. Among them, the two movable members are respectively connected to the corresponding contact assemblies. The two energy storage members are respectively connected to the corresponding movable members. When the movable members switch the working states of the corresponding contact assemblies, the energy storage members can first store energy and then release it, and during the release process, the switching speed is accelerated, and the contact assemblies are driven to maintain the switched working state.

[0007] Based on the above embodiments of the present application, when it is necessary to switch the power supply, the driving module drives the conversion module, and then drives the contact assembly through the conversion module to realize the switching between the closing and opening working states. Specifically, when the conversion module is working, the moving part drives the corresponding contact assembly to complete the switching process when it moves. During this process, the moving part drives the energy storage part to store energy first and then release it. During the release process of the energy storage part, it can push the moving part to accelerate the moving speed, thereby increasing the opening or closing speed of the contact assembly and improving the switching speed of the working state, so as to protect the electrical equipment. At the same time, after the energy storage part is released, it can also drive the contact assembly to maintain the working state after switching.

[0008] In some embodiments, the two contact assemblies are respectively set as the first contact and the second contact, and both the first contact and the second contact have two working states of opening and closing.

[0009] The two moving parts are respectively set as the first moving part and the second moving part. The first moving part and the second moving part are respectively detachably connected to the driving module. The driving module can selectively drive the first moving part or the second moving part to move, wherein the first moving part is connected to the first contact and the second moving part is connected to the second contact.

[0010] The two energy storage parts are respectively set as the first energy storage part and the second energy storage part. The first energy storage part is connected to the first moving part. When the first moving part switches the working state of the first contact, the first energy storage part can store energy first and then release it, and can push to accelerate the switching speed during the release process, and maintain the first contact in the working state after switching. The second energy storage part is connected to the second moving part. When the second moving part switches the working state of the second contact, the second energy storage part can store energy first and then release it, and can push to accelerate the switching speed during the release process, and maintain the second contact in the working state after switching.

[0011] Based on the above embodiments of the present application, the contact assembly is divided into the first contact and the second contact, and the first contact and the second contact respectively correspond to two different power supply lines, so as to realize the switching of the power supply by changing the working states of the first contact and the second contact. At the same time, the moving parts are correspondingly set as the first moving part and the second moving part, and the energy storage parts are correspondingly set as the first energy storage part and the second energy storage part to respectively increase the switching speed when the working states of the first contact and the second contact are switched.

[0012] In some embodiments, the conversion module further includes a first bracket, and both the first movable member and the second movable member are rotatably provided on the first bracket. The first energy storage member includes a first sliding rod and a first spring. The first spring is provided on the first sliding rod. The first movable member is connected to the first sliding rod, and when the first movable member moves, it can move relative to the first sliding rod to first compress and then release the first spring. When the first spring is released, it pushes the first movable member to move faster. The second energy storage member includes a second sliding rod and a second spring. The second spring is provided on the second sliding rod. The second movable member is connected to the second sliding rod, and when the second movable member moves, it can move relative to the second sliding rod to first compress and then release the second spring. When the second spring is released, it pushes the second movable member to move faster.

[0013] Based on the above embodiments of the present application, specific limitations are respectively imposed on the first energy storage member and the second energy storage member. When the first movable member moves, it first compresses and then releases the first spring, that is, the energy storage and release of the first energy storage member are realized. Similarly, when the second movable member moves, the energy storage and release of the second energy storage member are realized by compressing and releasing the second spring.

[0014] In some embodiments, two driving holes are provided at the connection positions between the contact component and the movable member on the first bracket, and the first movable member and the second movable member are respectively at least partially arranged in the driving holes. Third limiting parts are respectively arranged on the first movable member and the second movable member, and fourth limiting parts are arranged on the moving paths of the third limiting parts in the driving holes.

[0015] Based on the above embodiments of the present application, by setting the abutting contact between the first limiting part and the second limiting part, the stroke of the first movable member and the second movable member can be limited when they move, reducing the impact on the components in the switch body when their strokes are too large, thereby prolonging the service life of the components in the switch body.

[0016] In some embodiments, the conversion module further includes a first gear, a second gear, and a third gear. The first gear is directly or indirectly connected to the first movable member to drive the first movable member to move, and the second gear is directly or indirectly connected to the second movable member to drive the second movable member to move. The third gear can be meshed and driven with the first gear and the second gear respectively, and the driving module is connected to the third gear and drives the third gear to rotate. Among them, the first gear, the second gear, and the third gear are all set as semi-gears.

[0017] Based on the above embodiments of the present application, by setting the first gear, the second gear, and the third gear with the structure of semi-gears, when the third gear rotates driven by the driving module, the third gear is meshed and driven with one of the first gear and the second gear. For example, when the third gear rotates counterclockwise, it drives the first gear to rotate clockwise, thereby driving the first movable member to move, realizing alternative driving, and further driving the subsequent power supply line switching process.

[0018] In some embodiments, the driving module includes an intermediate connecting member, a driving motor, and / or a driving main shaft. The intermediate connecting member is connected to the third gear to drive the third gear to rotate. The driving motor is connected to the intermediate connecting member through a first transmission structure to drive the intermediate connecting member to rotate. The driving main shaft is connected to the intermediate connecting member through a second transmission structure to drive the intermediate connecting member to rotate.

[0019] Based on the above embodiments of the present application, by setting the driving motor as the power source to drive the intermediate connecting member and then drive the third gear to rotate, the subsequent driving process is completed to switch the power supply. Or, by setting the driving main shaft, the driving main shaft is rotated manually during use to drive the intermediate connecting member to achieve subsequent transmission and power supply switching. Or, both can be set at the same time. Among them, the specific structures of the first transmission structure and the second transmission structure can be set in any suitable manner.

[0020] In some embodiments, a first connecting block is provided at one end of the first gear facing the first movable member, and a first connecting hole is provided on the first movable member. The first connecting block is inserted into the first connecting hole to drive the first movable member to move through the first gear. Among them, the first connecting block can move limitedly in the first connecting hole. A fourth connecting block is provided at one end of the second gear facing the second movable member, and a fourth connecting hole is provided on the second movable member. The fourth connecting block is inserted into the fourth connecting hole to drive the second movable member to move through the second gear. Among them, the fourth connecting block can move limitedly in the fourth connecting hole.

[0021] Based on the above embodiments of the present application, the power transmission between the first gear and the first movable member is realized through the cooperation of the first connecting block and the first connecting hole, and the power transmission between the second gear and the second movable member is realized through the cooperation between the fourth connecting block and the fourth connecting hole. Further, by setting that the first connecting block can rotate limitedly in the first connecting hole, there is a vacant stroke when the first gear drives the first movable member, which can reduce the impact when the components contact during the transmission process to a certain extent and improve the mechanical life of each component. Similarly, by setting that the fourth connecting block can rotate limitedly in the fourth connecting hole, the impact when the components contact can also be reduced, and the mechanical life can be prolonged.

[0022] In some embodiments, the first contact includes a first moving contact and two first stationary contacts. The first moving contact has at least two first moving contact points. The two first stationary contacts are correspondingly arranged on the moving paths of the two first moving contact points. One of the first stationary contacts is connected to a first power supply, and the other first stationary contact is connected to an electrical device. The second contact includes a second moving contact and two second stationary contacts. The second moving contact has at least two second moving contact points. The two second stationary contacts are correspondingly arranged on the moving paths of the two second moving contact points. One of the second stationary contacts is connected to a second power supply, and the other second stationary contact is connected to the electrical device.

[0023] Based on the above embodiments of the present application, by specifically defining the structures of the first contact and the second contact, and by arranging the first stationary contact on the moving path of the first moving contact point, when the first moving contact moves driven by the first moving member, the two first moving contact points can be respectively in contact with the two first stationary contacts to realize the closing and conduction of the first contact. Conversely, when the first moving contact point is separated from the first stationary contact, the opening can be completed. Similarly, the closing and opening of the second contact are realized through the contact and separation between the second moving contact point and the second stationary contact. After the first contact is closed, the first power supply is conducted to the electrical device. After the second contact is closed, the second power supply is conducted to the electrical device. Thus, the switching of the power supply is realized through the above arrangement.

[0024] In some embodiments, there are multiple switch bodies. The first moving contacts in the multiple switch bodies are connected in sequence, and the second moving contacts in the multiple switch bodies are connected in sequence.

[0025] Based on the above embodiments of the present application, by arranging multiple switch bodies, the switching of the power supply for multiple electrical devices can be realized simultaneously, and the power supply switching in the emergency power supply state can be realized simultaneously.

[0026] According to the second aspect of the present application, a power supply system is provided. The power supply system includes a first power supply, a second power supply, and the above-mentioned automatic transfer switch electrical appliance. The first power supply and the second power supply are respectively connected to the same electrical device through the automatic transfer switch electrical appliance.

[0027] Based on the above embodiments of the present application, the power supply system can realize the switching between the first power supply and the second power supply through the automatic transfer switch electrical appliance. At the same time, through the arrangement of structures such as the first energy storage member and the second energy storage member, the switching process is made faster, thereby protecting the electrical device.

Detailed implementation manners

[0042] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0043] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Usually, the components of the embodiments of the present application described and illustrated herein can be arranged and designed in various different configurations.

[0044] Therefore, the detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application to be protected, but merely represents the selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0045] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0046] In the description of the present application, it should be noted that, unless otherwise stated, the orientation or positional relationship indicated by terms such as "inner" and "outer" is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of this application is usually placed during use. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application. In addition, terms such as "first" and "second" are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0047] In the description of the present application, it should also be noted that, unless otherwise clearly specified and limited, the terms "set" and "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0048] In the prior art, an automatic transfer switch usually has a mechanical interlock structure and an electrical interlock structure. When specifically performing the conversion, the opening and closing operations are driven by a motor. At this time, the opening and closing speeds of the product only depend on the conversion speed of the driving motor. In this case, the opening and closing speeds of the product usually can only be maintained between 0.8 - 1 second, the contact making and breaking speeds are relatively slow, which easily leads to equipment shutdown and restart, and at the same time, it is also easy to damage the electrical equipment.

[0049] To solve the above problems in the prior art, according to the first aspect of the present application, embodiments of the present application provide an automatic transfer switch. As shown in Figures 1 to 5 , the automatic transfer switch includes a driving module 1, a conversion module 2, and at least one switch body 3 connected in sequence. The driving module 1 can drive the conversion module 2. The switch body 3 includes two contact assemblies. The conversion module 2 can respectively convert the working states of the corresponding contact assemblies. The conversion module 2 includes two movable members and two energy storage members. The two movable members are respectively detachably connected to the driving module 1. The driving module 1 can selectively drive the movable members to move. Among them, the two movable members are respectively connected to the corresponding contact assemblies. The two energy storage members are respectively connected to the corresponding movable members. When the movable member switches the working state of the corresponding contact assembly, the energy storage member can first store energy and then release it, and during the release process, it can push to accelerate the switching speed and drive the contact assembly to maintain the switched working state.

[0050] Based on the above embodiments of the present application, when power supply switching is required, the driving module 1 drives the conversion module 2, and then drives the contact assembly through the conversion module 2 to realize the switching between the closing and opening working states. Specifically, when the conversion module 2 works, the moving part drives the corresponding contact assembly to complete the switching process during its movement. During this process, the moving part drives the energy storage part to store energy first and then release it. During the release process of the energy storage part, it can push the moving part to accelerate its movement speed, thereby increasing the opening or closing speed of the contact assembly and improving the switching speed of the working state, so as to protect the electrical equipment. At the same time, after the energy storage part is released, it can also drive the contact assembly to maintain the switched working state.

[0051] Specifically, in the present application, referring to Figure 3 and Figure 4 as shown, the two contact assemblies can be respectively set as the first contact 31 and the second contact 32. Both the first contact 31 and the second contact 32 have two working states: opening and closing. Thus, when the automatic transfer switch is in use, the first contact 31 and the second contact 32 are used for the connection and conduction between two different power supplies and the electrical equipment. The opening and closing working states of the first contact 31 and the second contact 32 respectively correspond to the disconnection and conduction of the corresponding connection lines.

[0052] Furthermore, in the present application, the two moving parts can be respectively set as the first moving part 21 and the second moving part 22. The first moving part 21 and the second moving part 22 are respectively detachably connected to the driving module 1. The driving module 1 can selectively drive the first moving part 21 or the second moving part 22 to move. Among them, the first moving part 21 is connected to the first contact 31, and the second moving part 22 is connected to the second contact 32.

[0053] Based on the above embodiments of the present application, the two moving parts are specifically divided into the first moving part 21 and the second moving part 22, which are respectively used to drive the switching processes of the first contact 31 and the second contact 32.

[0054] Referring to Figure 5 and Figure 6 as shown, in some embodiments of the present application, the two energy storage parts can be respectively set as the first energy storage part 23 and the second energy storage part 24. The first energy storage part 23 is connected to the first moving part 21. When the first moving part 21 switches the working state of the first contact 31, the first energy storage part 23 can store energy first and then release it, and increase the switching speed during the release process, and maintain the first contact 31 in the switched working state. The second energy storage part 24 is connected to the second moving part 22. When the second moving part 22 switches the working state of the second contact 32, the second energy storage part 24 can store energy first and then release it, and increase the switching speed during the release process, and maintain the second contact 32 in the switched working state.

[0055] Based on the above embodiments of the present application, during the movement of the first movable member 21, the first energy storage member 23 is first compressed, and then the first energy storage member 23 is released. The release process of the first energy storage member 23 can in turn push the first movable member 21 to increase the speed of the first movable member 21, thereby accelerating the opening and closing speeds and improving the switching speed. Similarly, the opening and closing speeds of the second contact 32 are improved by the arrangement of the second energy storage member 24.

[0056] Specifically, through the arrangements of the first energy storage member 23 and the second energy storage member 24 above, the switching speed of the automatic transfer switch electrical appliance can be shortened. Usually, the opening and closing speeds can be switched within 10 milliseconds, reducing the possibility of damage to electrical equipment during the switching process.

[0057] Further, in the present application, the drive module 1 as the switching power source can usually be set as a device such as a motor. Compared with directly increasing the rotation speed of the power source, for example, replacing the motor with a higher rotation speed, the above arrangements in the present application can avoid the greater impact force brought by the high-speed motor and reduce the influence of the impact force on the mechanical life of components such as the first contact 31 and the second contact 32.

[0058] At the same time, when the power source of the drive module 1 is set as a motor, with the power unchanged, replacing the motor with a higher rotation speed will result in a decrease in the torque of the motor, which will affect the driving effect during transmission. In order to ensure both the rotation speed and torque of the motor, a larger motor needs to be replaced, and both will lead to an increase in the overall volume and cost of the product. However, the above arrangements in the present application can achieve the effect of accelerating the opening and closing speeds during switching while maintaining a smaller volume and lower cost.

[0059] In the present application, the first movable member 21 and the second movable member 22 can be set as any suitable structure.

[0060] Reference Figure 5 As shown in, in an exemplary embodiment provided by the present application, both the first movable member 21 and the second movable member 22 are set as shaft structures. At this time, the drive module 1 can drive the first movable member 21 and the second movable member 22 to rotate, and then alternately drive the first contact 31 and the second contact 32 to rotate to complete the opening and closing processes, realizing the switching of the power supply line.

[0061] In some other embodiments of the present application, the first movable member 21 and the second movable member 22 can also be set as other structures, such as a crank-slider mechanism, etc. The present application does not make specific limitations on this.

[0062] In the present application, the first energy storage member 23 and the second energy storage member 24 can be set as any suitable structure, such as a compression spring structure and a torsion spring structure, etc.

[0063] Reference Figure 6 and Figure 7 As shown in and , in an exemplary embodiment provided by the present application, the conversion module 2 further includes a first bracket 25, and both the first movable member 21 and the second movable member 22 are rotatably arranged on the first bracket 25. The first energy storage member 23 includes a first sliding rod 231 and a first spring 232. The first spring 232 is arranged on the first sliding rod 231. The first movable member 21 is connected to the first sliding rod 231, and when the first movable member 21 moves, it can move relative to the first sliding rod 231 to first compress and then release the first spring 232. When the first spring 232 is released, it pushes the first movable member 21 to move faster. The second energy storage member 24 includes a second sliding rod 241 and a second spring 242. The second spring 242 is arranged on the second sliding rod 241. The second movable member 22 is connected to the second sliding rod 241, and when the second movable member 22 moves, it can move relative to the second sliding rod 241 to first compress and then release the second spring 242. When the second spring 242 is released, it pushes the second movable member 22 to move faster.

[0064] Based on the above embodiments of the present application, when the first movable member 21 moves, the first spring 232 is first compressed and then released, that is, the energy storage and release of the first energy storage member 23 are realized. Similarly, when the second movable member 22 moves, the energy storage and release of the second energy storage member 24 are realized by compressing and releasing the second spring 242.

[0065] Specifically, when both the first movable member 21 and the second movable member 22 are set as a rotating shaft structure, both the first movable member 21 and the second movable member 22 are rotatably arranged on the first bracket 25.

[0066] Reference Figure 6 and Figure 7 As shown in and , at this time, a first chute 233 may be formed along the length direction at the first end of the first sliding rod 231. A first connecting column 234 is slidably arranged in the first chute 233. The first connecting column 234 is connected to one of the first movable member 21 and the first bracket 25, and the second end of the first sliding rod 231 is connected to the other. The first spring 232 is sleeved on the first sliding rod 231, and one end of the first spring 232 abuts against the first connecting column 234, and the other end of the first spring 232 abuts against the first movable member 21 or the first bracket 25 connected to the second end of the first sliding rod 231.

[0067] At this time, as the first movable member 21 rotates, for example, when the first connecting column 234 is connected to the first bracket 25, the first connecting column 234 slides along the first chute 233 to compress the first spring 232. After the first sliding rod 231 moves to the horizontal state, when the first movable member 21 continues to rotate, the first spring 232 is released. The elastic potential energy when the first spring 232 is released is used to push the rotation speed of the first movable member 21 to increase, and further the opening and closing speeds of the first contact 31 are increased.

[0068] Similarly, when the second movable member 22 rotates, the second spring 242 is first compressed and then released. When the second spring 242 is released, it pushes the second movable member 22 to increase its rotation speed, thereby increasing the opening and closing speeds of the second contact 32.

[0069] Reference Figure 7 As shown in [[reference]], in some embodiments of the present application, the conversion module 2 may further include a first gear 26, a second gear 27, and a third gear 28. The first gear 26 is directly or indirectly connected to the first movable member 21 to drive the first movable member 21 to move. The second gear 27 is directly or indirectly connected to the second movable member 22 to drive the second movable member 22 to move. The third gear 28 can be meshed and driven with the first gear 26 and the second gear 27 respectively. The driving module 1 is connected to the third gear 28 and drives the third gear 28 to rotate. Among them, the first gear 26, the second gear 27, and the third gear 28 are all set as half gears.

[0070] Based on the above embodiments of the present application, by providing the first gear 26, the second gear 27, and the third gear 28 with a structure of half gears, when the third gear 28 rotates driven by the driving module 1, the third gear 28 is meshed and driven with one of the first gear 26 or the second gear 27. For example, when the third gear 28 rotates counterclockwise, it drives the first gear 26 to rotate clockwise, thereby driving the first movable member 21 to move, realizing alternative driving, and further driving the subsequent power supply line switching process.

[0071] In the present application, any suitable setting can be selected for the specific connection manners between the first gear 26 and the first movable member 21 and between the second gear 27 and the second movable member 22.

Or, by setting the driving main shaft 13, when in use, the driving main shaft 13 is rotated manually to drive the intermediate connecting member 11 to realize the subsequent transmission and power supply switching.

Conversely, when the first moving contact separates from the first static contact 312, the opening can be completed. Similarly, the closing and opening of the second contact 32 are realized through the contact and separation between the second moving contact and the second static contact 322.

For example, when both the first movable member 21 and the second movable member 22 are set as rotating shaft structures, the second connecting block 213 can be set as a convex block, the second connecting hole 313 can be set as an arc-shaped groove, and the arc-shaped groove corresponds to a partial rotation path of the convex block when rotating with the first movable member 21. Or the second connecting block 213 and the second connecting hole 313 can refer to the structure and connection method of the first connecting block 261 and the first connecting hole 212. Similarly, the third connecting block 222 and the third connecting hole 323 can also be correspondingly set in the above manner.

[0086] Based on the above embodiments of the present application, the power transmission between the first movable member 21 and the first moving contact 311 is realized through the cooperation of the second connecting block 213 and the second connecting hole 313, and the power transmission between the second movable member 22 and the second moving contact 321 is realized through the cooperation between the third connecting block 222 and the third connecting hole 323. Further, by setting that the second connecting block 213 can rotate limitedly in the second connecting hole 313, there is a vacant stroke when the first movable member 21 drives the first moving contact 311, which can reduce the impact when the components contact during the transmission process to a certain extent and improve the mechanical life of each component. Similarly, by setting that the third connecting block 222 can rotate limitedly in the third connecting hole 323, it can also reduce the impact when the components contact and extend the mechanical life.

When the first movable member 21 and the second movable member 22 are both set as rotating shafts, the first movable member 21 and the second movable member 22 are at least partially rotatably arranged in the connection holes 291. A first limiting portion 292 is arranged in the connection holes 291, and second limiting portions 211 are respectively arranged on the first movable member 21 and the second movable member 22.

For example, a drive protective casing, a conversion protective casing, and a switch protective casing can be separately provided. The integrally provided protective casing can improve the production efficiency during production and processing, and at the same time has a better insulation protection effect. The separately provided protective casings are convenient for disassembly and later maintenance, and can better adapt to the adaptive adjustment of each module.
