DETAILED DESCRIPTION

[0041] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0042] In the description of the present application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0043] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0044] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0045] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0046] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0047] In electrical equipment, the insulation performance of the conductor and the insulating gas in the housing is crucial. Moisture will reduce the dielectric strength of the insulating gas because moisture will ionize under the action of the electric field, creating ionic conductive paths and increasing the possibility of leakage. For example, in high-voltage electrical equipment, even a small amount of moisture may cause partial discharge, which will gradually damage the insulating medium over time and eventually cause equipment failure.

[0048] The inventors of the present application have noticed that it is difficult to remove moisture directly from the insulating gas. If you try to deal with moisture directly in the shell, it may interfere with the normal operation of the conductor, and the operation in a closed shell will be limited by space and operational convenience. In addition, adding desiccant and other water-absorbing substances directly into the shell may bring other problems. For example, the desiccant may decompose and produce impurities after absorbing moisture, or the desiccant may move during the operation of the equipment, affecting the stability of the equipment.

[0049] The inventor of the present application attempts to place the moisture absorption component in a device outside the housing. Placing the moisture absorption component outside the housing can reduce the space inside the housing, making the conductor layout inside the housing more reasonable. Figure 1 , Figure 1The schematic diagram of the structure of a part of the switch device in the embodiment of the related art is shown, and the part of the structure of the switch device includes a housing 10, a sub-cavity 20, an electrical connector 30, and a moisture absorption component 40, wherein the moisture absorption component 40 also includes a frame 41, and the moisture absorption component 40 is arranged on the housing 10. However, the inventor of the present application also noticed that in the case where the moisture absorption component 40 is arranged on the outer surface of the housing 10, when the electrical connector 30 is energized, the electrical connector 30 generates high voltage, and the moisture absorption component 40 is higher than the surface of the housing 10, which may cause the electric field distribution to be distorted. Under the high-voltage environment, the electric field may produce a local electric field concentration phenomenon on the protruding part, that is, the part higher than the surface of the housing 10. In the case where the moisture absorption component 40 is arranged on the inner surface of the housing 10, when the electrical connector 30 is energized, due to the holes on the surface of the housing 10, the existence of the openings may destroy the uniformity of the electric field, making the electric field unevenly distributed inside the device, thereby reducing the insulation performance of the device.

[0050] Therefore, in the related art, the manner of setting the desiccant component 40 on the shell 10 can affect the size of the electric field and may even bring safety hazards, causing the humidity of the insulating gas in the switch device to increase, the insulating gas to leak, the gas to produce arcing, and other situations that affect the operation of the switch device.

[0051] Based on this, the inventors of the present application have discovered through in-depth research that, under the premise of not affecting the flow and strength of the electrical connector, the electrical connector can be designed to be hollow. When the electrical connector is turned on, the components of the internal cavity of the electrical connector and the electrical connector are at the same potential. The internal components can be shielded by the electrical connector itself and will not affect the electric field. This can improve the phenomenon of local discharge of the device caused by uneven electric field distribution, improve the insulation and safety performance of the device, and at the same time reduce production costs.

[0052] Figure 2 A schematic diagram of a cross-sectional structure of a portion of a switch device provided in some embodiments of the present application is shown; Figure 3 A schematic diagram of a partial cross-sectional structure of a switch device provided in some other embodiments of the present application is shown; for ease of explanation, only the content related to the embodiments of the present application is shown.

[0053] Please refer to Figure 2 and Figure 3 An embodiment of the present application provides a switch device, wherein the switch device 100 includes a housing 110 and an electrical connection assembly 120 .

[0054] Specifically, the housing 110 has a plurality of mutually independent sub-cavities 111, and the sub-cavities 111 are used to contain insulating gas. Figure 1 As shown, only one sub-cavity 111 in the housing 110 is illustrated.

[0055] The “multiple independent sub-cavities 111” can be understood as each sub-cavity 111 is independent of each other, so that the environment inside each sub-cavity 111 is relatively independent. The shape and size of the sub-cavity 111 can be set according to actual conditions and are not specifically limited here.

[0056] It should be noted that the insulating gas may be sulfur hexafluoride (SF6) gas or other environmentally friendly gases (such as nitrogen, etc.), which may be set according to actual conditions, and the embodiments of the present application do not impose specific restrictions on this.

[0057] A plurality of electrical connection components 120 are disposed in all sub-cavities 111 in a one-to-one correspondence. It can be understood that each electrical connection component 120 is located in a corresponding sub-cavity 111, and the electrical connection components 120 of two adjacent sub-cavities 111 can be connected to each other.

[0058] The electrical connection component 120 includes an electrical connection member 121 , a separator 122 and a moisture absorption component 123 .

[0059] Specifically, the electrical connector 121 has a receiving cavity Q and an opening K connected to the receiving cavity Q, and the receiving cavity Q is connected to the corresponding sub-cavity 111 by means of the opening K. The electrical connector 121 is a component for conducting electricity. It should be noted that the shape and size of the electrical connector 121 in each sub-cavity 111 may be different or the same, and may be set according to actual conditions.

[0060] The shape and size of the accommodating cavity Q and the opening K can be set according to actual conditions, and the embodiment of the present application does not impose any specific restrictions on this.

[0061] The accommodating cavity Q is connected to the corresponding sub-cavity 111 via the opening K. It can be understood that when the insulating gas is accommodated in the corresponding sub-cavity 111, the insulating gas can also enter the accommodating cavity Q via the opening K.

[0062] The electrical connector 121 has a plurality of connection terminals 121 a , which are disposed on the cavity walls of the corresponding sub-cavities 111 , and all the electrical connectors 121 are electrically connected via the corresponding connection terminals 121 a .

[0063] The electrical connector 121 has multiple connection terminals 121a. It is understandable that the electrical connector 121 can have 2 connection terminals 121a, 3 connection terminals 121a, or 4 connection terminals 121a. It can be set according to actual conditions, and the embodiments of the present application do not impose any restrictions on this.

[0064] It should be noted that among the multiple connection terminals 121a of the electrical connector 121, the multiple connection terminals 121a can be connected in series and / or in parallel, which can be selected according to actual conditions and is not specifically limited. Figure 2 , a connection terminal 121 a in the electrical connection member 121 is schematically shown.

[0065] All electrical connectors 121 are electrically connected by means of corresponding connection terminals 121a, and the following situations may occur: 1. Adjacent connection terminals 121a may be connected together by bolts; 2. Adjacent connection terminals 121a may also be plug-in connections, where one connection terminal 121a is configured as a plug shape, and the other connection terminal 121a is configured as a socket shape. The selection may be made according to actual conditions, and of course, electrical connection may also be made in other ways, as long as all electrical connectors 121 can be electrically connected by means of corresponding connection terminals 121a, and the embodiments of the present application do not impose specific restrictions on this.

[0066] The partition 122 is disposed in the accommodating chamber Q and divides the accommodating chamber Q into a first chamber Q1 and a second chamber Q2. An opening K is disposed on the chamber wall of the first chamber Q1, and a plurality of first through holes (not shown in the figure) are disposed on the partition 122. The first chamber Q1 and the second chamber Q2 are connected by means of the plurality of first through holes.

[0067] The partition 122 may refer to a component that divides the accommodating chamber Q into a first chamber Q1 and a second chamber Q2. It should be noted that the first chamber Q1 may be a cavity or may include a plurality of sub-cavities, which may be configured according to actual conditions. Figure 3 As shown, an opening K may be provided on the cavity wall of the accommodating cavity Q, and the partition 122 is provided in the opening K of the accommodating cavity Q. In this way, the partition 122 may not separate the accommodating cavity Q into the first cavity Q1 and the second cavity Q2.

[0068] A plurality of first through holes are provided on the partition 122 , so that the insulating gas can enter the containing cavity Q when the sub-cavity 111 contains the insulating gas.

[0069] The moisture absorption component 123 is disposed in the second cavity Q2. The moisture absorption component 123 may refer to a component for absorbing moisture in the insulating gas to improve the insulating performance of the insulating gas. The moisture absorption component 123 is disposed in the second cavity Q2, and the partition 122 can also more stably accommodate the moisture absorption component 123 in the second cavity Q2.

[0070] In this way, by providing a shell 110 and a plurality of electrical connection components 120, a plurality of independent sub-cavities 111 of the shell 110 contain insulating gas, which can provide a more stable insulating environment for the electrical connection component 120. The insulating gas can effectively reduce the generation of electric arcs and reduce the risk of discharge accidents of the switch device 100. Next, by providing a housing cavity Q of the electrical connector 121 to be connected to the sub-cavity 111 through an opening K, the insulating gas can more fully surround the electrical connector 121, further enhancing the insulation effect. By providing a plurality of connecting terminals 121a on the cavity wall of the sub-cavity 111, all the electrical connectors 121 are electrically connected by means of the corresponding connecting terminals 121a, so that the electrical connection of the electrical connectors 121 of two adjacent sub-cavities 111 can be achieved. The moisture absorption component 123 is arranged in the second cavity Q2, which can effectively absorb the moisture in the insulating gas. The arrangement of the partition 122 can more stably accommodate the moisture absorption component 123 in the second cavity Q2. After the moisture absorption component 123 absorbs the moisture of the insulating gas, the multiple first through holes on the partition 122 can prevent possible impurities from entering the sub-cavity 111. At the same time, when the electrical connector 121 is powered on, the moisture absorption component 123 and the partition 122 and other components accommodated in the accommodating cavity Q of the electrical connector 121 can have the same potential as the electrical connector 121, reducing the impact on the electric field. While absorbing the moisture in the insulating gas and improving the insulation of the device, it can reduce the number of installed components, making it easier to install, thereby reducing production costs. Therefore, the embodiment of the present application improves the stability and reliability of the entire switch device 100.

[0071] In some embodiments, please refer to Figure 2 The moisture absorption component 123 includes a plurality of absorption units 123a, and the absorption units 123a are configured in a spherical shape.

[0072] It is understandable that the adsorption units 123a can play a role in absorbing moisture independently of each other. The adsorption unit 123a refers to a component that absorbs moisture in the insulating gas. Specifically, the moisture absorption component 123 can select a suitable number of adsorption units 123a according to the size of the accommodating cavity Q, so as to better absorb moisture in the insulating gas.

[0073] Thus, by setting the moisture absorption component 123 to include a plurality of adsorption units 123a, and constructing the adsorption unit 123a into a spherical shape, the adsorption surface area can be increased. Compared with other shapes, the spherical surface area is the largest under the same volume, so that each adsorption unit 123a can contact the surrounding insulating gas, further increasing the effective area for adsorbing moisture in the insulating gas, effectively drying the insulating gas, and improving the insulation of the device. At the same time, since the spherical shape has the characteristic of isotropy, the adsorption unit 123a can more evenly adsorb the air in the insulating gas, thereby improving the reliability of the device.

[0074] In some embodiments, please refer to Figure 2 , the adsorption unit 123a is configured as a molecular sieve; and / or, the diameter of the adsorption unit 123a is 1 mm to 6 mm.

[0075] Specifically, the main components of molecular sieves are aluminum hydroxide, water glass, and alkali metals, which usually have strong adsorption capacity and can effectively adsorb moisture in the insulating gas to improve the dryness of the insulating gas.

[0076] Since the size of water molecules matches the pore size of the molecular sieve, the molecular sieve can selectively adsorb water molecules while adsorbing less other gases in the device (such as insulating gas), so that the composition and performance of the insulating gas are not affected.

[0077] The diameter of the adsorption unit 123a is set to 1 mm to 6 mm. Specifically, the diameter of the adsorption unit 123a can be 1 mm, 2 mm, 3 mm, 4 mm, 5.1 mm or 6 mm. Of course, the diameter of the adsorption unit 123a can also be other values ​​from 1 mm to 6 mm, which can be selected according to actual conditions, and is not specifically limited in the embodiments of the present application.

[0078] Thus, by configuring the adsorption unit 123a as a molecular sieve, the dryness of the insulating gas can be improved. And / or, by setting the diameter of the adsorption unit 123a to 1 mm to 6 mm, the adsorption unit 123a can effectively adsorb moisture in the insulating gas while improving the efficiency of adsorption of moisture.

[0079] In some embodiments, please refer to Figure 2 The moisture-absorbing component 123 also includes a packaging component 123b.

[0080] The package 123b has a receiving cavity r and a plurality of second through holes (not shown in the figure) connected to the receiving cavity r, and the adsorption unit 123a is received in the receiving cavity r. Specifically, the package 123b may refer to a component that packages a plurality of adsorption units 123a together. It is understandable that the package 123b is provided with a receiving cavity r inside, and the receiving cavity r can be used to place the adsorption unit 123a, and a plurality of second through holes are provided on the package 123b to enable the insulating gas to enter and exit the receiving cavity r, so that the moisture in the insulating gas can enter the receiving cavity r and be absorbed by the adsorption unit 123a, and at the same time, the dried insulating gas can be discharged.

[0081] The shape and size of the packaging member 123b can be set according to the number of adsorption units 123a, and this embodiment of the present application does not impose any specific limitation on this.

[0082] In this way, by providing the packaging member 123b to accommodate the adsorption unit 123a in the accommodating cavity r, multiple adsorption units 123a can be more stably placed in the accommodating cavity Q. During the operation of the switch device, it may be subjected to vibration, impact, etc. The packaging member 123b can reduce the occurrence of the multiple adsorption units 123a moving randomly inside the device, thereby improving the stability and reliability of the device.

[0083] In some embodiments, please refer to Figure 2 The material of the packaging piece 123b is non-woven fabric.

[0084] Thus, the material of the packaging member 123b is non-woven fabric, which can make the insulating gas flow into or out of the accommodating cavity r more smoothly. At the same time, the texture of the non-woven fabric is usually soft, so that the non-woven fabric can more flexibly accommodate multiple adsorption units 123a according to the shape and number of the adsorption units 123a. The material of the non-woven fabric can also improve the anti-aging property of the packaging member 123b, extend the service life of the packaging member 123b, and reduce the production cost.

[0085] Of course, in some other embodiments, the material of the packaging member 123b may also be other materials, as long as the insulating gas can enter and exit the accommodating cavity r, and the embodiment of the present application does not impose any specific limitation on this.

[0086] In some embodiments, please refer to Figure 2 The partition 122 and the cavity wall of the accommodating cavity Q are detachably connected.

[0087] Specifically, the partition 122 and the cavity wall of the accommodating cavity Q can be detachably connected by means of bolt connection, snap connection or slot connection. The specific detachable connection method can be set according to actual conditions, and the embodiment of the present application does not impose specific restrictions on this.

[0088] In this way, by arranging the partition 122 and the cavity wall of the accommodating cavity Q to be detachably connected, the partition 122 can be more conveniently connected to the cavity wall of the accommodating cavity Q, thereby improving the reliability of the device.

[0089] In some embodiments, please refer to Figure 2 The electrical connector 121 includes a stepped portion b disposed on the cavity wall of the accommodating cavity Q.

[0090] Specifically, the partition 122 abuts against the step portion b and is detachably connected to the step portion b. The step portion b may be formed by processing the cavity wall of the accommodating cavity Q, such as by cutting, casting, etc. The shape, size, and location of the step portion b may be set according to actual conditions, and the embodiment of the present application does not impose any specific restrictions on this.

[0091] The step portion b can play a role in positioning and supporting the partition 122. The step portion b can make the partition 122 more accurately installed in the accommodating cavity Q, and the step portion b can also reduce the occurrence of unnecessary displacement of the partition 122.

[0092] The separator 122 is detachably connected to the step portion b, and there are many ways of detachable connection. For example, it can be connected by bolts, threaded holes are set at corresponding positions of the step portion b and the separator 122, and the separator 122 and the step portion b are fixed together by bolts; it can also be a snap connection, and mutually cooperating snap structures are designed on the step portion b and the separator 122 respectively. The snaps are tightened during installation to achieve connection, which is more convenient to open during disassembly.

[0093] Thus, by abutting the partition 122 against the step portion b and being detachably connected to the step portion b, the partition 122 can be more stably connected to the cavity wall of the accommodating cavity Q. In addition, when the partition 122 needs to be replaced, the partition 122 can be removed from the step portion b more quickly.

[0094] In some embodiments, please refer to Figure 2 The housing 110 includes a housing body 112 and a plurality of insulating members 113 .

[0095] The shell body 112 has a cavity c. A plurality of insulating members 113 are disposed in the cavity c and divide the cavity c into a plurality of mutually independent sub-cavities 111 . The connecting terminals 121 a are disposed on corresponding insulating members 113 .

[0096] Specifically, multiple insulating members 113 are arranged in the cavity c of the shell body 112, and the insulating members 113 can divide the cavity c into multiple independent sub-cavities 111. The insulating members 113 can be made of ceramic or epoxy resin, etc., and can be arranged according to actual conditions, and the embodiment of the present application does not impose specific restrictions on this.

[0097] In this way, by arranging a plurality of insulating members 113 in the cavity c and dividing the cavity c into a plurality of independent sub-cavities 111, when an electrical fault or insulating gas leakage occurs in a sub-cavity 111, the fault range can be reduced due to the independence of each sub-cavity 111, thereby improving the overall safety and reliability of the device. At the same time, by arranging the connection terminal 121a on the corresponding insulating member 113, the insulating performance of the insulating member 113 can be utilized to more effectively reduce the occurrence of accidental electrical contact between the connection terminal 121a and the shell body 112 or other non-related conductive components, thereby enhancing the electrical insulation of the entire switch device 100. In addition, the relatively stable structure of the insulating member 113 can provide a more fixed and reliable installation environment for the connection terminal 121a, reduce the possibility of loosening or displacement of the connection terminal 121a due to vibration, external force impact, etc., and improve the stability and continuity of the electrical connection.

[0098] In some embodiments, please refer to Figure 2 , the shell body 112 includes a plurality of sub-bodies 112a.

[0099] The two adjacent sub-bodies 112a are detachably connected. An insulating member 113 is disposed at the connection between the two adjacent sub-bodies 112a. The sub-bodies 112a and the insulating member 113 connected to the sub-bodies 112a define a sub-cavity together.

[0100] Specifically, two adjacent sub-bodies 112a are arranged to be detachably connected, and the detachable connection method can be a bolt connection, a snap connection, a connection between a slot and a block, etc., which can be arranged according to actual conditions.

[0101] The sub-body 112a and the insulating part 113 connected thereto jointly define the sub-cavity 111, that is, the insulating part 113 can be a part of the boundary of the sub-cavity 111, and the insulating part 113 and the inner wall of the sub-body 112a and other structures together enclose a relatively closed and independent space that can be used to accommodate insulating gas and connect the corresponding connection terminal 121a.

[0102] Thus, by providing a detachable connection between two adjacent sub-bodies 112a, when assembling the switch device, the operator can more conveniently connect the sub-bodies 112a as required, and when it is necessary to maintain or overhaul the inside of the device or replace a sub-body 112a of the shell body 112, the connected sub-bodies 112a can be more easily disassembled, further improving the convenience and flexibility of operation. At the same time, providing an insulating member 113 at the connection between two adjacent sub-bodies 112a can enhance the insulation between the adjacent sub-bodies 112a, and can also improve the sealing of the connection, thereby improving the insulation and safety of the entire switch device 100.

[0103] In some embodiments, the switch device 100 further includes a plurality of valve elements (not shown in the drawings).

[0104] Specifically, a valve member is disposed on the cavity wall of each sub-cavity 111. It can be understood that a valve member is disposed on the cavity wall of each sub-cavity 111.

[0105] When the switch device is used, the insulating gas can be introduced into the sub-cavity 111 through the valve, and the valve can be closed after sufficient insulating gas is introduced. At the same time, a valve is provided on the cavity wall of each sub-cavity 111, and the gas pressure of the insulating gas in each sub-cavity 111 can also be independently controlled.

[0106] Thus, by setting the valve, it is possible to better control the insulating gas from entering and exiting the sub-cavity 111. When the switch device 100 needs to be fed with insulating gas, by opening the valve, the external insulating gas can enter the sub-cavity 111 more smoothly, so that the insulating gas reaches a suitable gas pressure and gas content, thereby improving the insulation of the device.

[0107] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0108] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
