Description

Technical Field

[0001] This utility model relates to the field of switch protection device technology, and in particular to an air switch protective cover. Background Technology

[0002] An air circuit breaker (BCB) is a commonly used switching device with overload protection function, widely used in substations. During substation operation and maintenance, BCBs are often placed in a fixed open or closed position. To prevent accidental operation or contact, various methods are often used for sealing and protection. Currently, the common method is to use yellow tape for sealing, but this makes operation inconvenient, prevents tripping in case of overload in the closed position, and is also aesthetically unappealing. Alternatively, a protective cover can be used to enclose the BCB. However, since the protective cover needs to be installed simultaneously with the BCB installation, it cannot flexibly protect the BCB within the substation without affecting its performance.

[0043] 2. Air switch. Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0045] The following is combined with Figures 1-8 The air switch protective cover provided by the present invention will be described in detail through specific embodiments and application scenarios.

[0046] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides an air switch protective cover 1, including: a base 11, a transparent cover 12, and an indicator 13.

[0047] The base 11 is used to be installed on the side of the end of the air switch 2. The transparent cover 12 is rotatably disposed on the base 11 to cover the outside of the air switch 2. The width of the transparent cover 12 and the width of the base 11 are the same as the width of the air switch 2.

[0048] Indicator sign 13 is located on transparent cover 12 and is used to warn of the operation of air switch 2.

[0049] Understandably, substations typically install a row of air switches 2 side by side, and air switches 2 for important circuits need to be sealed to prevent accidental contact. The top of the air switch 2 is a metal baffle.

[0050] The base 11 is used to provide a mounting support for the transparent cover 12 and the indicator 13. In this embodiment, the base 11 is mounted on the metal baffle at the top of the air switch 2.

[0051] Specifically, the base 11 can be mounted on the metal baffle using fasteners or glue.

[0052] A transparent cover 12 is installed over the outside of the air switch 2 and is suspended relative to the air switch 2, meaning there is a certain gap between the transparent cover 12 and the air switch 2. This provides sufficient space for the air switch 2 to trip, preventing interference with the transparent cover 12 when the air switch 2 trips and affecting its tripping protection function. Furthermore, the cover is transparent, allowing the user to observe the open / closed state of the air switch 2 without having to lift the cover, making it convenient for the user to monitor the air switch 2's status. The transparent cover 12 is rotatable relative to the base 11, allowing the user to easily open the transparent cover 12 when operating the air switch 2 and close it after operation, thus protecting the air switch 2.

[0053] Furthermore, the width of the transparent cover 12 is the same as the width of the air switch 2. When multiple air switches 2 are arranged side by side, multiple transparent covers 12 can be installed and protected relative to multiple air switches 2 without interference between adjacent transparent covers 12. Moreover, since the base 11 is not fixed to the air switch 2, the protective cover 1 can be installed after the air switch 2 in the substation has been installed. Compared with the previous protective cover 1 which needed to be installed synchronously with the air switch 2, the protective cover 1 in this embodiment can be used to protect the air switch 2 in the operating substation, and the protective cover 1 can also be flexibly replaced and repaired without affecting the normal operation of the air switch 2.

[0054] The indicator 13 is used to warn about the operation of the air switch 2. For example, when the air switch 2 is in the closed state, the indicator 13 warns against opening the switch, and when the air switch 2 is in the open state, the indicator 13 warns against closing the switch, so that users can clearly and intuitively understand the instructions for preventing misoperation of the air switch 2 through the indicator 13.

[0055] The air switch protective cover 1 provided by this utility model has a base 11 installed on the side of the end of the air switch 2, and a transparent cover 12 rotatably mounted on the base 11. This allows the transparent cover 12 to be suspended and cover the outside of the air switch 2, which does not affect the tripping protection function of the air switch 2, and can protect the air switch 2 from accidental operation. Users can also observe the status of the air switch 2 through the transparent cover 12. Furthermore, the width of the transparent cover 12 and the width of the base 11 are the same as the width of the air switch 2, that is, the width of the protective cover 1 does not exceed the width of the air switch 2. For air switches 2 arranged in a row, the protective cover 1 can be installed on each air switch 2 without interference, which improves the installation flexibility of the air switch protective cover 1.

[0056] like Figure 4 As shown, the transparent cover 12 of this embodiment includes a main body 121, a bottom 122 and a connecting part 123.

[0057] There are two connecting parts 123, which are respectively located on both sides of the first end of the main body 121, and the connecting parts 123 are rotatably mounted on the base 11.

[0058] The second end of the main body 121 is connected to the bottom 122.

[0059] Understandably, the main body 121 covers the front of the air switch 2, and the bottom 122 covers the bottom of the air switch 2. Both the main body 121 and the bottom 122 are used to protect the air switch 2 to prevent accidental operation.

[0060] The connecting part 123 rotates relative to the base 11, thereby driving the main body 121 and the bottom 122 to rotate relative to the base 11. In this embodiment, there are two connecting parts 123, and the two connecting parts 123 drive the main body 121 to rotate from both sides of the main body 121, thereby improving the stability of the rotation of the main body 121.

[0061] like Figure 1 As shown, in this embodiment, the main body 121, the connecting part 123, and the bottom 122 are all connected by a rounded transition.

[0062] Understandably, the connection between the main body 121, the connecting part 123, and the bottom 122 is a rounded transition connection, which allows the main body 121 to smoothly transition with the connecting part 123 and the bottom 122. The absence of abrupt sharp corners ensures the aesthetics of the transparent cover 12 and makes the operation of the transparent cover 12 safer.

[0063] Specifically, the main body 121, the connecting part 123, and the bottom 122 can all be made of plastic.

[0064] like Figure 4As shown, in this embodiment, the connecting part 123 is provided with a connecting block 1231 on the side facing the base 11, and the base 11 is provided with a connecting groove 111 on the side facing the connecting part 123.

[0065] The connecting block 1231 is rotatably connected to the connecting groove 111.

[0066] It is understood that in this embodiment, the connecting block 1231 is a cylindrical block, and the connecting groove 111 is a cylindrical groove. The connecting block 1231 is inserted into the connecting groove 111 and can rotate relative to it, thereby realizing the rotation of the connecting part 123 relative to the base 11. The structure of the connecting block 1231 and the connecting groove 111 is simple and easy to process and install.

[0067] like Figure 4 and Figure 5 As shown, a positioning block 1232 is provided on the side of the connecting block 1231 in this embodiment.

[0068] A positioning groove 112 is provided on the side of the connecting groove 111. There are two positioning grooves 112, which are arranged at intervals along an arc with the center of the connecting groove 111 as the center.

[0069] When the connecting part 123 rotates around the base 11, the positioning block 1232 is engaged in one of the two positioning slots 112 to limit the opening and closing position of the transparent cover 12.

[0070] Understandably, in order to prevent excessive force from causing the transparent cover 12 to rotate too much relative to the base 11 when the user opens and closes the transparent cover 12, this embodiment provides two positioning grooves 112 to limit the rotation angle of the transparent cover 12.

[0071] When the transparent cover 12 is lifted, the connecting part 123 rotates around the base 11. When it rotates to its maximum angle, the positioning block 1232 engages in the positioning groove 112 near the top of the transparent cover 12, restricting the rotation of the transparent cover 12 away from the air switch 2. When the transparent cover 12 is closed, the connecting part 123 rotates around the base 11. When it rotates to its maximum angle, the positioning block 1232 engages in the positioning groove 112 near the bottom of the transparent cover 12, restricting the rotation of the transparent cover 12 towards the air switch 2. By limiting the rotation angle of the transparent cover 12 when it is lifted and closed, the transparent cover 12 rotates within a reasonable rotation angle, ensuring the reliability of the rotation of the transparent cover 12.

[0072] like Figure 4 As shown, the bottom 122 of this embodiment is provided with a toggle bar 1221. The toggle bar 1221 extends along the width direction of the air switch 2.

[0073] Understandably, when the user opens and closes the transparent cover 12, the toggle bar 1221 can increase the friction with the user's hand, making the toggle operation of the transparent cover 12 more reliable.

[0074] like Figure 1 As shown, the sign 13 in this embodiment is rotatably mounted on the transparent cover 12.

[0075] The front of indicator 13 indicates that air switch 2 is prohibited from being opened, and the back of indicator 13 indicates that air switch 2 is prohibited from being closed.

[0076] Understandably, the indicator 13 can be flipped relative to the transparent cover 12. Users can flip the indicator 13 so that the front or back of the indicator 13 faces the outer side of the transparent cover 12. Compared to switching between the front and back of the indicator 13 by disassembly and assembly, the indicator 13 in this embodiment can conveniently switch the warning instructions for the operation of the air switch 2 by flipping the indicator 13.

[0077] like Figure 4 and Figure 6 As shown, the sign 13 in this embodiment includes a bar sign 131 and a connecting shaft 132.

[0078] Two connecting shafts 132 are provided, and the two connecting shafts 132 are respectively located on both sides of the bar-shaped sign 131. The transparent cover 12 is provided with connecting lugs 124.

[0079] Two connecting lugs 124 are provided, and two connecting shafts 132 are inserted into the corresponding connecting lugs 124.

[0080] Understandably, the rotation of the bar sign 131 relative to the transparent cover 12 is achieved by the rotation of the connecting shaft 132 relative to the connecting lug 124. Furthermore, since there are two connecting shafts 132 and two connecting lugs 124, both sides of the bar sign 131 can rotate, which improves the stability of the rotation of the bar sign 131.

[0081] like Figure 6 , Figure 7 and Figure 8 As shown, the sign 13 in this embodiment also includes a snap-fit ​​plate 133. The snap-fit ​​plate 133 is arranged perpendicularly to the bar sign 131.

[0082] The transparent cover 12 is provided with a first snap-fit ​​groove 125 and a second snap-fit ​​groove 126. The first snap-fit ​​groove 125 is located on one side of the line connecting the two connecting lugs 124, and the second snap-fit ​​groove 126 is located on the other side of the line connecting the two connecting lugs 124.

[0083] The front and back of the bar sign 131 have different warning texts. The card plate 133 is inserted into the first card slot 125 or the second card slot 126 to warn of the operation of the air switch 2.

[0084] Understandably, the first snap-fit ​​slot 125 and the second snap-fit ​​slot 126 extend along the width direction of the transparent cover 12, and the first end of the snap-fit ​​plate 133 extending out of the bar 131 can be inserted into the first snap-fit ​​slot 125, and the second end of the snap-fit ​​plate 133 extending out of the bar 131 can be inserted into the second snap-fit ​​slot 126.

[0085] When the bar sign 131 rotates around the two connecting lugs 124, it rotates to the top of the transparent cover 12. The first end of the snap-fit ​​plate 133 is inserted into the first snap-fit ​​groove 125, which fixes the snap-fit ​​plate 133. The position of the bar sign 131 is fixed, and without user operation, the bar sign 131 cannot rotate. The front of the bar sign 131 faces outward, displaying the words "Do Not Open the Circuit" to remind the user not to perform the opening operation. When the bar sign 131 rotates to the bottom 122 of the transparent cover 12, the second end of the snap-fit ​​plate 133 is inserted into the second snap-fit ​​groove 126, which fixes the snap-fit ​​plate 133. The position of the bar sign 131 is fixed, and without user operation, the bar sign 131 cannot rotate. The back of the bar sign 131 faces outward, displaying the words "Do Not Close the Circuit" to remind the user not to perform the closing operation.

[0086] like Figure 1 As shown, a strong magnet 113 is embedded in the base 11 of this embodiment.

[0087] A strong magnet 113 is located on the side of the base 11 away from the transparent cover 12.

[0088] Understandably, because the base 11 has a built-in strong magnet 113, when installing the protective cover 1, the base 11 only needs to be attached to the metal baffle above the air switch 2, and when removing the protective cover 1, the base 11 only needs to be forcefully pulled off the metal baffle. Compared with other connection methods, the connection of the strong magnet 113 is easy to disassemble and install, and can be operated quickly, making it particularly suitable for operating the air switch 2 in substations.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
