Description

Technical Field

[0001] The present invention relates to a contact device for contacting a switch device within a manufacturing container to manufacture the switch device, and a manufacturing apparatus for forming or inspecting a switch device. Background Technology

[0002] In the prior art, switching devices are known, for example, in the form of vacuum switching tubes. A typical vacuum switching tube includes a fixed contact pin at one end and a movable contact pin at the opposite end. Inside the switching device, each of the two contact pins has a contact disc disposed opposite to it. By moving the movable contact pin, different distances between the two contact discs can be adjusted to provide different switching positions of the switching device.

[0003] To achieve the high dielectric strength required for such switchgear, it is typically formed after assembly. To do this, the switchgear is first positioned within a sealed container. During formation, high voltage is applied to the contact plates in different switching positions. This applied high voltage selectively generates a breakdown discharge, whose arc melts or vaporizes defects and minor protrusions on the contact plate surface. In this way, the surface quality is gradually improved until the required dielectric strength for the switchgear is achieved.

[0004] Furthermore, the current dielectric strength of such switching devices can be checked by applying high voltage within a closed inspection container.

[0005] During the fabrication or inspection of switchgear, it may be necessary to apply high voltage to components other than the contact pins. These other components are also known as lateral contact points.

[0006] The location of the lateral contact points varies depending on the type and size of the specific switchgear, especially its height and diameter.

[0007] In traditional manufacturing facilities, such as those forming or inspecting containers, workers must select the contact components for the lateral contact parts based on the type and size of the switchgear to be manufactured and manually install them onto the manufacturing facility. Therefore, traditional equipment and methods are complex in terms of manufacturing time and personnel usage in configuring the manufacturing facility to accommodate specific switchgear.

[0008] Furthermore, in conventional manufacturing facilities, for each additional lateral contact point that needs to be touched during the manufacturing of switchgear, the operator must manually adjust the contact component. Summary of the Invention

[0009] Based on the known prior art, the object of the present invention is to provide an improved contact device for contacting switching devices, and an improved manufacturing apparatus for forming or inspecting switching devices.

[0010] This objective is achieved by a contact device having the features of claim 1. Advantageous further improvements are derived from the dependent claims, the description, and the drawings.

[0011] Accordingly, a contact device is proposed for contacting a switchgear within a manufacturing container used for manufacturing, particularly forming or inspecting, switchgear. The contact device includes a rigid contact assembly for applying a manufacturing voltage to the switchgear, wherein the rigid contact assembly has a receiving element. The contact device also includes a first adjusting mechanism for moving the rigid contact assembly in a height direction, and a second adjusting mechanism for providing a length adaptation of the contact device in a longitudinal direction. Both the first and second adjusting mechanisms are capable of withstanding the manufacturing voltage, which is a high voltage used in manufacturing switchgear.

[0012] Specifically, the manufacturing voltage can be a high voltage used for forming or inspecting the switchgear. Furthermore, the receiving element can be configured to contact the lateral contact portion of the switchgear.

[0013] In this document, "rigid" contact assembly refers to a rigid contact assembly whose base is rigid, meaning its geometry is fixed. Because this rigid contact assembly has a receiving element, this receiving element can be moved longitudinally, for example, by means of a second adjusting mechanism. Thus, the rigid contact assembly can be adjusted for the radial dimension of the lateral contact portion of the switchgear to apply a manufacturing voltage to the switchgear, for example, to adjust the diameter of the switchgear. In this way, the second adjusting mechanism can provide a length adaptation of the contact device in the longitudinal direction.

[0014] Because the contact device has a first adjustment mechanism for moving the rigid contact assembly along the height direction, the rigid contact assembly can be adjusted for the axial dimension of the lateral contact portion of the switchgear in order to apply a manufacturing voltage to the switchgear, for example, to adjust the height of the switchgear and thus the height position of the lateral contact portion.

[0015] Furthermore, since the first and second adjustment mechanisms can withstand the manufacturing voltage, the rigid contact assembly can be adjusted relative to the switching device in the longitudinal direction (radial) and in the height direction (axial). Therefore, the first and second adjustment mechanisms can be controlled by corresponding control units. In this way, contact of the lateral contact points inside the manufacturing container can be achieved in an automated or semi-automated manner.

[0016] This paper assumes that the proposed contact device is aligned with the main axis of a typical switching device, such as a vacuum switch tube, wherein the main axis of the switching device passes centrally through the two contact pins. Therefore, in this paper, axial refers to the direction along the main axis of the switching device, and thus relates to the height of the switching device. Radial refers to the direction transverse to the main axis of the switching device, and thus relates to the width or diameter of the switching device.

[0017] In this case, the expression "applicable," such as a component being "capable of withstanding voltage," means that the component will not be substantially damaged or even destroyed when a load is applied, especially when a high voltage is applied in this case. In this case, the first and second regulating mechanisms are capable of withstanding manufacturing voltage and are therefore designed to withstand high voltage without being significantly damaged by it. This means, for example, that the first and second regulating mechanisms do not have any electrical components that could be damaged by the high voltage required for molding.

[0018] According to one embodiment, the first adjustment mechanism can have a threaded spindle or a vertical DC drive, particularly a vertical hydraulic drive or a vertical pneumatic drive.

[0019] Additionally or alternatively, the second regulating mechanism may have a horizontal fluid drive, particularly a horizontal hydraulic drive or a horizontal pneumatic drive.

[0020] In this article, the terms “vertical” or “horizontal” refer to adjustment or movement along the height or longitudinal direction, respectively.

[0021] With the aid of the threaded spindle and the vertical or horizontal fluid drive, a drive for the first and second adjustment mechanisms can be provided, both of which are capable of withstanding manufacturing voltage.

[0022] According to another embodiment, the contact device can have an inner component and an outer component, the inner component being configured to be disposed inside the manufacturing container and the outer component being configured to be disposed outside the manufacturing container. The inner component can include the rigid contact component and the first adjustment mechanism and the second adjustment mechanism. The outer component can include a control unit for controlling the first adjustment mechanism and / or the second adjustment mechanism. In particular, the outer component can include a fluid controller for controlling the vertical and / or horizontal fluid actuator.

[0023] By setting the internal and external components, the control unit can be decoupled from the manufacturing voltage, thereby enabling, for example, the installation of electrical and electronic components within the control unit.

[0024] According to another embodiment, the first adjustment mechanism and / or the second adjustment mechanism can be configured for stepless adjustment of the rigid contact assembly. In this way, it is possible to precisely contact a variety of different lateral contact points.

[0025] According to another embodiment, the contact device can have a vertical guide tube. The threaded spindle can be housed within the vertical guide tube, and the threaded spindle can be electrically shielded by means of the vertical guide tube. The vertical guide tube can withstand the manufacturing voltage, and therefore the vertical guide tube is used to supply voltage to the receiving element. In this way, the threaded spindle can be decoupled from the manufacturing voltage.

[0026] Furthermore, the contact device may also include a parallel guide tube arranged substantially parallel to the vertical guide tube, and may have a fluid supply line for supplying the horizontal fluid actuator. In this way, the supply or control of the horizontal fluid actuator can be ensured even when the rigid contact assembly moves or adjusts in the height direction.

[0027] Furthermore, the first adjusting mechanism can have a linkage guide that connects the threaded spindle to the rigid contact assembly. Additionally, the contact device can have an electrically insulated drive shaft for rotating the threaded spindle. The linkage guide can include a slider disposed in the vertical guide tube, by means of which the rotational motion of the threaded spindle can be converted into the vertical motion of the rigid contact assembly. Specifically, the insulated drive shaft can have a dielectric strength higher than the manufacturing voltage. Thus, the insulated drive shaft can constitute a functional interface between mechanical components located inside the manufacturing container and electrical components located outside the manufacturing container.

[0028] According to another embodiment, the contact device can include a variable contact assembly for contacting the switching device with a manufacturing voltage, wherein the variable contact assembly can be detachably fixed to the receiving element. In other words, for a first / second switching device having a first / second diameter, a first / second variable contact assembly having a first / second length can be provided, wherein the first / second length of the variable contact assembly matches the first / second diameter, and thus the corresponding radial position of the lateral contact portion. Thus, by providing multiple variable contact assemblies with different lengths, additional adjustment in the longitudinal direction can be provided. Since the variable contact assembly can be detachably fixed to the receiving element, the corresponding specific switching device can be installed quickly and easily.

[0029] For example, the variable contact assembly can be secured to the receiving element by means of magnetic couplings, plug couplings, threaded connections, or bayonet locking mechanisms. In this way, the fixing and / or removal of the variable contact assembly can even be performed in an automated or semi-automated manner.

[0030] Alternatively or additionally, the variable contact assembly may have a spring-loaded contact cover for applying the manufacturing voltage to the switching device, wherein the contact cover is movably fixed to the variable contact assembly in the longitudinal direction. For example, the variable contact assembly may have a ferromagnetic plate for the magnetic coupling at one end and a spring-loaded contact cover at the opposite end. Because the contact cover is spring-loaded and movably fixed to the variable contact assembly in the longitudinal direction, additional adjustment in the longitudinal direction can be provided, which is particularly suitable for compensating for the diameter tolerances of the switching device. In this way, particularly robust contact at the lateral contact points can be achieved for the respective switching devices.

[0031] According to a further development plan (which is compatible with all embodiments and examples currently described), the manufacturing voltage can be higher than 50kV. In current applications, the manufacturing voltage can be any value in the range of 70kV to 1200kV.

[0032] The aforementioned task is also accomplished by a manufacturing apparatus having the features of claim 13. Advantageous further developments of this apparatus are derived from this specification and the accompanying drawings.

[0033] Accordingly, a manufacturing apparatus for forming or inspecting switchgear is provided. The manufacturing apparatus includes the aforementioned manufacturing container and the aforementioned contact device. Specifically, the outer component can be disposed outside the manufacturing container, and the inner component can be disposed inside the manufacturing container. Attached Figure Description

[0034] Preferred embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. The drawings schematically illustrate: Figure 1a , Figure 1b A cross-sectional view of a typical switching device is shown; Figure 2a , Figure 2b A schematic diagram of the manufacturing apparatus is shown; and Figures 3 to 5 A partial three-dimensional cross-sectional view of the contact device is shown. Detailed Implementation

[0035] The preferred embodiments will now be described with reference to the accompanying drawings. In different drawings, the same, similar, or functionally identical elements are represented by the same reference numerals. To avoid repetition, repeated descriptions of these elements are omitted in some cases.

[0036] Figure 1aA schematic longitudinal sectional view of a typical switchgear 2 is shown, the switchgear being in the form of a vacuum switch tube 2. A first end flange and second end flanges 2a, 2b enclose the tubular base 2c of the switchgear 2. A fixed contact pin 2f extends through the first end flange 2a into the interior of the switchgear 2. A movable contact pin 2g is supported by a linear bearing 2d with a built-in bellows 2e, disposed on the second end flange 2b. Inside the switchgear 2, the two contact pins 2f, 2g each have contact discs 2h, 2i. As shown in Figure 1, the main axis of the switchgear corresponds to the Z-axis of the Cartesian coordinate system. By moving the movable contact pin 2g along the Z-axis of the switchgear, different switching distances between the two contact discs 2h, 2i can be adjusted, thereby providing different switching positions of the switchgear 2.

[0037] Figure 1a Two lateral contact portions 3a and 3b of the switchgear 2 are also shown exemplarily and schematically. During manufacturing, particularly during the formation or inspection of the switchgear within the manufacturing container, a manufacturing voltage, in the form of a high voltage, should be applied to these lateral contact portions.

[0038] Figure 1b Two are illustrated schematically. Figure 1a Examples of switchgear are shown. The first example switchgear shown on the left has three lateral contact portions 3a to 3c, each with a corresponding height ha to hc and a radius r1. The second example switchgear 2 shown on the right has two lateral contact portions 3d and 3e, each with a corresponding height hd and he and a radius r2. Figure 1b As shown, the heights ha to he and the radii r1 and r2 of the two example switchgears are significantly different. The heights ha to he and the radii r1 and r2 are measured from the clamping point, at which the switchgear is clamped in the manufacturing container (e.g., at the end of one of the two contact pins 2g or 2f).

[0039] When these two example switchgear 2 are to be arranged or clamped in the same manufacturing container for molding or inspection, the contact devices for applying the manufacturing voltage to the lateral contact portions 3a to 3e must be adjusted accordingly in the height and longitudinal directions. In conventional contact devices, this adjustment is performed manually by a worker.

[0040] To better understand the various directions, this paper uniformly adopts the Cartesian coordinate system XYZ, whose origin can be located, for example, at the aforementioned clamping point. Furthermore, it is assumed that the switching device 2 and the proposed contact device 1 (see...) Figures 3 to 5 ) or the proposed manufacturing apparatus 100 (see Figure 2a , Figure 2b Align them as follows.

[0041] The main axis of the switchgear passes centrally through the two contact pins 2f and 2g, and is parallel to or coincides with the Z-axis. The main axis of the manufacturing device passes through clamping point 106 (see...). Figure 2a , Figure 2b The contact device's main axis corresponds to the height direction and is parallel to the switchgear's main axis or parallel to the Z-axis. The contact device's longitudinal axis corresponds to the longitudinal direction and is parallel to the X-axis.

[0042] Starting from clamping point 106, each lateral contact portion 3a to 3e can be uniquely determined by two distances: an axial distance, for example in the form of heights ha to he, and a radial distance, for example in the form of radii r1 and r2. Therefore, the axial / radial adjustment or adaptation described herein corresponds to the movement of the corresponding component of the proposed contact device 1 in the height / longitudinal direction or along the Z-axis / X-axis.

[0043] Figure 2a and Figure 2b The principle representation of the proposed manufacturing apparatus 100 is shown below. The manufacturing apparatus 100 includes a manufacturing container 4 having a lower clamping portion 102 and an upper clamping portion 104 for clamping the contact pins 2g and 2f of the switchgear 2. The lower clamping portion 102, together with the clamped contact pin 2g, forms an imaginary clamping point 106 corresponding to the origin of the XYZ coordinate system. The manufacturing apparatus 100 also includes the proposed contact device 1, having an inner component 16 and an outer component 18. The inner component is disposed inside the manufacturing container 4, and the outer component is disposed outside the manufacturing container 4. The inner component 16 is capable of withstanding a manufacturing voltage, wherein the manufacturing voltage is a high voltage used for manufacturing the switchgear 2, particularly for forming or inspecting the switchgear. The outer component 18 itself cannot withstand the manufacturing voltage; that is, the outer component 18 includes parts that would be damaged when subjected to the manufacturing voltage. However, the outer component 18 has a manufacturing voltage supply line 30 that feeds the manufacturing voltage from a voltage supply device through the outer component 18 to the inner component 16. The outer component 18 also includes a fluid supply line 12b, a control unit 20, and a fluid controller 21 for supplying or controlling the inner component 16. Components in the inner component 16 that may be sensitive to manufacturing voltage are electrically shielded inside the inner component, as will be discussed below. Figure 3 This needs to be explained.

[0044] Through the Figure 2a and Figure 2b A geometric comparison reveals that the inner component 16 is configured for axial and radial adjustment so as to contact the lateral contact portions 3 of the switching device 2, which are positioned differently in the Z and X directions.

[0045] Figure 3 , Figure 4 and Figure 5 Partial cross-sectional views of the proposed contact device 1 are shown schematically. Figure 3 The main components of the inner assembly 16 and the interface components 12b, 22, and 30 to the outer assembly 18 are shown. The contact device 1 includes a base housing 34, which serves as the structural foundation of the inner assembly 16 and also as the foundation for the interface components, particularly the fluid supply line 12b, the manufacturing voltage power supply line 30, and the insulated drive shaft 22 of the contact device 1. The base housing 34 can be arranged inside (not shown) and / or outside the manufacturing container 4.

[0046] To apply a manufacturing voltage to the lateral contact portion 3 of the switching device, the contact device 1 includes a rigid contact assembly 6 having a receiving element 8. A variable contact assembly 24, including a spring-loaded contact cover 28, is detachably fixed to the receiving element 8 for contacting the lateral contact portion 3.

[0047] To move the rigid contact assembly 6 along the Z-axis, i.e., to axially adjust the contact along the height direction Z, the contact device 1 includes a first adjustment mechanism 10, the movable parts of which are substantially arranged within a vertical guide tube 11a. More specifically, a threaded spindle 11 is rotatably mounted within the vertical guide tube 11a, which is driven by a motor arranged in the outer assembly 18 via an insulated shaft 22. The rotational movement of the threaded spindle 11 is converted into a linear displacement of the rigid contact assembly 6 along the height direction Z via a connecting rod guide 11b, on which the rigid contact assembly 6 is fixed.

[0048] As an alternative to the threaded spindle and connecting rod guide, the first adjustment mechanism 10 is particularly capable of having a vertical DC actuator, such as a vertical hydraulic actuator or a vertical pneumatic actuator, for moving the rigid contact assembly 6 along the height direction Z.

[0049] In order to move the receiving element 8 along the X-axis and thereby move the contact cover 28 arranged thereon, i.e. to make radial adjustment of the contact along the longitudinal direction X, the contact device 1 includes a second adjustment mechanism 12, the movable parts of which are basically arranged in or on the rigid contact assembly 6.

[0050] The second adjustment mechanism 12 has a horizontal fluid actuator 14, which is in the form of a horizontal pneumatic actuator 14. Alternatively, the horizontal fluid actuator 14 can also be configured as a horizontal hydraulic actuator 14.

[0051] The second adjustment mechanism 12 is supplied or controlled via a fluid supply line 12b. The fluid supply line 12b is arranged in a spiral configuration within a parallel guide tube 12a, which is aligned parallel to the vertical guide tube 11a and connected to the vertical guide tube via a base housing 34 and a rigid support arm 32. The spiral arrangement or winding of the fluid supply line 12b within the parallel guide tube 12a, along with the rigid support arm 32, enables fluid supply to the second adjustment mechanism 12 while maintaining an adjustable height. Accordingly, the two guide tubes 11a and 12a have substantially the same total height.

[0052] The first adjusting mechanism 10 is capable of withstanding the manufacturing voltage and is configured to transmit the manufacturing voltage from the manufacturing voltage supply line 30 via the vertical guide tube 11a and the connecting rod guide 11b disposed therein to the rigid contact assembly 6. The second adjusting mechanism 12 is capable of withstanding the manufacturing voltage and is configured to transmit the manufacturing voltage from the rigid contact assembly 6 via the guide element 46 for guiding the piston of the cylinder 48 to the receiving element 8 fixed on the piston. Thus, the manufacturing voltage is applied to the contact cover 28 of the variable contact assembly 24, which is detachably fixed to the receiving element 8.

[0053] Figure 4 A portion of the contact device 1 is shown, wherein the aforementioned variable contact assembly 24 is not installed. Radial and longitudinal adaptation is provided by the second adjustment mechanism. Figure 4 The first longitudinal adapter, designated L1, can be 30 mm, 20 mm, or 15 mm, for example, when using a pneumatic actuator. Therefore, the first longitudinal adapter L1 can be used, for example, to retract the receiving element 8 to prevent collision with the surrounding environment during height adjustment of the rigid contact assembly 6.

[0054] Figure 5 A portion of the contact device 1 is shown, which has a variable contact assembly 24 with an effective length L2. The effective length L2 represents the distance between the displacement element 6 and the spring-loaded contact cover 28. As described above, the variable contact assembly 24 can be selected according to the switching device to be manufactured. The maximum achievable effective length L2 depends on the stability of the fixing mechanism used to detachably fix the variable contact assembly 24 and the weight of the variable contact assembly itself. For example, when using… Figure 5 With the magnetic connector 26 shown, an effective length L2 between 20 mm and 300 mm can be achieved. By employing a more robust fixing mechanism, such as a threaded locking element or a bayonet locking element, an effective length L2 up to 1000 mm can be achieved. In other words, by means of the variable contact assembly 24, the maximum adjustable length of the contact device 1 in the longitudinal direction can be 1000 mm, 800 mm, 600 mm, 400 mm, 300 mm, 200 mm, or a value in between.

[0055] To reliably transmit the manufacturing voltage, the rigid contact assembly 6 has a cover 42, and the variable contact assembly 24 correspondingly has a cylindrical retainer 36, which can optionally contact the cover 42 in a voltage-transmitting manner even when the second adjustment mechanism 12 is operated. Furthermore, to robustly transmit the manufacturing voltage, the variable contact assembly 24 also has a contact 44 arranged between the cylindrical retainer 36 and a contact cover 28 spring-loaded thereon.

[0056] An automatic radial tolerance adapter is provided for compensating for the radial tolerance of the switchgear 2 by means of a spring-loaded contact cover 28.

[0057] As Figures 3 to 5 In an alternative to the illustrated embodiment, the second adjustment mechanism 12 can be implemented without the horizontal fluid actuator 14, and the length adaptation of the contact device in the longitudinal direction X can be provided solely by means of the variable effective length L2 of the variable contact assembly 24.
