[0011] In one possible implementation, the first plate is further provided with a first positioning hole, the second plate is provided with a second positioning hole coaxial with the first positioning hole, and the fixing part is provided with a third positioning hole. When the locking plate is rotated to the position where the abutting part is below the opening operation plate and in the locked state, the third positioning hole is located between the first positioning hole and the second positioning hole. The first limiting member passes through the first positioning hole, the third positioning hole and the second positioning hole to maintain the locked state.

[0012] In one possible implementation, the first plate is further provided with a fourth positioning hole, the second plate is provided with a fifth positioning hole coaxial with the fourth positioning hole, and the abutment part is provided with a sixth positioning hole. When the locking plate rotates to the position where the abutment part is located in the receiving groove and is in the unlocked state, the sixth positioning hole is located between the fourth positioning hole and the fifth positioning hole. The second limiting member passes through the fourth positioning hole, the sixth positioning hole and the fifth positioning hole to maintain the unlocked state.

[0015] In one possible implementation, the first plate and the first fixing plate are integrally formed; and / or,

[0016] The second plate and the second fixing plate are integrated into one unit.

[0017] In one possible implementation, the first limiting member includes a first limiting part and a first handle part connected to the first limiting part.

[0018] In one possible implementation, the first limiting part is further provided with a first limiting hole, which is located below the second plate and is used for the third connector to pass through. The third connector is used to restrict the upward movement of the first limiting part.

[0019] In one possible implementation, the abutment portion has a notch located at the end of the locking plate away from the first connector.

[0020] Compared to existing technologies, the technical solution provided by this utility model has at least the following beneficial effects: The manual opening / closing handle includes an opening operation plate and an closing operation plate, and both the manual opening / closing handle and the fixing frame are connected to the first side plate of the housing. When the manual opening / closing handle is in maintenance mode, rotating the locking plate connected to the fixing frame moves the abutting part of the locking plate to the bottom of the opening operation plate. If the operator accidentally moves the manual opening / closing handle, the interference of the abutting part on the opening operation plate restricts the opening operation plate from continuing to rotate toward the abutting part, thereby preventing accidental operation of the manual opening / closing handle from causing tripping. When the manual opening / closing handle is in normal operation, rotating the locking plate connected to the fixing frame restores its original position, causing the abutting part of the locking plate to move away from the bottom of the opening operation plate. This design can improve the phenomenon of accidental tripping caused by accidental operation of the manual opening / closing handle during live-line work. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] In the description of this utility model, it should be understood that the terms "upper", "lower", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0038] The purpose of this utility model is to provide a pole-mounted switch tripping interlocking anti-misoperation device, which can improve the phenomenon of tripping caused by accidental operation of the manual tripping handle during live-line work.

[0039] Please see Figures 1 to 7To achieve the above objectives, this utility model provides a pole-mounted switch opening interlocking anti-misoperation device, suitable for live-line work on 10kV pole-mounted switches. The device includes a housing 100, a manual opening / closing handle 200, a fixing frame 300, and an interlocking plate 400. The housing 100 includes a first side plate 110. The manual opening / closing handle 200 is rotatably connected to the first side plate 110 and includes an opening operation plate 210 and a closing operation plate 220. The manual opening / closing handle 200 can rotate relative to the first side plate 110 to open or close the switch. The manual opening / closing handle 200 is rotatably connected to the first side plate 110 via a rotating shaft. The opening operation plate 210 and the closing operation plate 220 are located on opposite sides of the first side plate 110. Figure 1 From the perspective of rotation, the tripping operation plate 210 is located on the left side of the rotating shaft, while the closing operation plate 220 is located on the right side of the rotating shaft. The tripping operation plate 210 can be used for tripping when rotated counterclockwise, and is in the closing state otherwise. The fixing frame 300 is fixedly connected to the first side plate 110. The locking plate 400 is rotatably connected to the fixing frame 300. The locking plate 400 is provided with an abutment part 410. The abutment part 410 can be moved to the bottom of the tripping operation plate 210 to abut against the tripping operation plate 210 to restrict the tripping operation plate 210 from continuing to rotate toward the abutment part 410.

[0040] The manual opening and closing handle 200 includes an opening operation plate 210 and a closing operation plate 220. The manual opening and closing handle 200 and the fixing frame 300 are both connected to the first side plate 110 of the housing 100. When the manual opening / closing handle 200 is in maintenance mode, rotating the locking plate 400 connected to the fixing frame 300 moves the abutment part 410 of the locking plate 400 below the tripping operation plate 210. If the operator accidentally moves the manual opening / closing handle 200, the interference of the abutment part 410 with the tripping operation plate 210 restricts the tripping operation plate 210 from continuing to rotate toward the abutment part 410, thus preventing the circuit breaker from tripping due to accidental operation of the manual opening / closing handle 200. When the manual opening / closing handle 200 is in normal operation, rotating the locking plate 400 connected to the fixing frame 300 restores its original position, causing the abutment part 410 of the locking plate 400 to move away from below the tripping operation plate 210, without affecting remote control of the manual opening / closing handle 200 for opening and closing operations. This setting can improve the phenomenon of accidental tripping caused by accidental operation of the manual opening / closing handle 200 during live-line work.

[0041] In one possible implementation, the fixing frame 300 includes a first plate 310 and a second plate 320 arranged vertically and parallel to each other. The first plate 310 is located above the second plate 320, and a receiving groove is formed between the first plate 310 and the second plate 320. The locking plate 400 is provided with a fixing part 420 located in the receiving groove. The first plate 310 is provided with a first connecting hole 311, the second plate 320 is provided with a second connecting hole 321 coaxial with the first connecting hole 311, and the fixing part 420 is provided with a third connecting hole 421 coaxial with the first connecting hole 311. The first connecting member is sequentially passed through the first connecting hole 311, the third connecting hole 421, and the second connecting hole 321 and then fixed by the first fixing member, so that the locking plate 400 can rotate around the axis of the first connecting member.

[0042] The first connector may be, but is not limited to, a bolt with a smooth rod and a threaded section, and the first fastener may be, but is not limited to, a nut adapted to the threaded section. Specifically, after the bolt passes through the first connecting hole 311, the third connecting hole 421, and the second connecting hole 321 from top to bottom, the bolt head abuts against the upper surface of the first plate 310, the smooth rod of the bolt extends into the first connecting hole 311, the third connecting hole 421, and the second connecting hole 321, and the threaded section of the bolt extends at least partially below the second connecting hole 321. By fitting the nut onto the threaded section and tightening it, the locking plate 400 can rotate around the axis of the smooth rod.

[0043] In one possible implementation, the first plate 310 is further provided with a first positioning hole 312, the second plate 320 is provided with a second positioning hole 322 coaxial with the first positioning hole 312, and the fixing part 420 is provided with a third positioning hole 422. When the locking plate 400 rotates to the position where the abutment part 410 is below the tripping operation plate 210 and in a locked state, the third positioning hole 422 is located between the first positioning hole 312 and the second positioning hole 322. The first limiting member 500 passes through the first positioning hole 312, the third positioning hole 422 and the second positioning hole 322, restricting the locking plate 400 from rotating around the axis of the first connecting member, thereby maintaining the locked state and solving the problem of accidental tripping caused by the manual tripping handle 200 during live-line work. Specifically, the first limiting member 500 includes a first limiting part 510 and a first handle part 520 connected to the first limiting part 510. The first limiting part 510 is used to pass through the first positioning hole 312, the third positioning hole 422 and the second positioning hole 322, and the first handle part 520 is used to abut against the upper surface of the first plate 310.

[0044] In some embodiments, the first positioning hole 312, the second positioning hole 322, and the third positioning hole 422 may be configured as circular holes. The first limiting portion 510 of the first limiting member 500 may be configured as a columnar structure adapted to the circular hole. The maximum width of the cross-section of the first handle portion 520 of the first limiting member 500 perpendicular to the axis of the circular hole is greater than the diameter of the circular hole, so as to prevent the first limiting member 500 from falling out of the first positioning hole 312, the second positioning hole 322, and the third positioning hole 422. In other embodiments, based on the first positioning hole 312, the second positioning hole 322, and the third positioning hole 422 being configured as circular holes, a groove may be formed in the hole wall of the circular hole, so that the circular hole and the groove form a continuous irregular hole.

[0045] In this design, a portion of the groove and the circular hole form a rectangular hole. The first limiting part 510 can be configured as a cuboid adapted to the rectangular hole. The cross-section of the cuboid perpendicular to the axis of the circular hole is smaller than the cross-section of the rectangular hole perpendicular to the axis of the circular hole. Furthermore, the maximum width of the cross-section of the first handle part 520 of the first limiting member 500 perpendicular to the axis of the circular hole is greater than the maximum width of the cross-section of the rectangular hole perpendicular to the axis of the circular hole, ensuring that the first handle part 520 can abut against the upper surface of the first plate 310 or the top edge of the first positioning hole 312. In addition, the first limiting part 510 is also provided with a first limiting hole 511, which is located below the second plate 320 and is used for the passage of a third connecting member. The third connecting member is used to restrict the upward movement of the first limiting part 510, thereby ensuring the limiting effect of the first limiting member 500 on the locking plate 400.

[0046] In one possible implementation, the first plate 310 is further provided with a fourth positioning hole 313, the second plate 320 is provided with a fifth positioning hole 323 coaxial with the fourth positioning hole 313, and the abutment portion 410 is provided with a sixth positioning hole 411. When the locking plate 400 rotates to the position where the abutment portion 410 is located in the receiving groove and in the unlocked state, the sixth positioning hole 411 is located between the fourth positioning hole 313 and the fifth positioning hole 323. The second limiting member passes through the fourth positioning hole 313, the sixth positioning hole 411, and the fifth positioning hole 323, restricting the locking plate 400 from rotating around the axis of the first connecting member, thereby maintaining the unlocked state. Specifically, the second limiting member includes a second limiting part and a second handle part connected to the second limiting part. The second limiting part is used to pass through the fourth positioning hole 313, the sixth positioning hole 411, and the fifth positioning hole 323, and the second handle part is used to abut against the upper surface of the first plate 310. The second limiting member can be the same as the first limiting member for general applicability. The abutment portion 410 is provided with a notch 412, which is located at the end of the locking plate 400 away from the first connector. When the locking plate 400 is rotated to the position where the abutment portion 410 is located in the receiving groove, there is a notch 412 between the locking plate 400 and the first side plate 110, which facilitates subsequent application of force at the notch 412 position to rotate the locking plate 400 out of the receiving groove.

[0047] In some embodiments, the fourth positioning hole 313, the fifth positioning hole 323, and the sixth positioning hole 411 may be configured as circular holes, and the second limiting part of the second limiting member may be configured as a columnar structure adapted to the circular hole. The maximum width of the cross-section of the second handle part of the second limiting member perpendicular to the axis of the circular hole is greater than the diameter of the circular hole, so as to prevent the second limiting member from falling out of the fourth positioning hole 313, the fifth positioning hole 323, and the sixth positioning hole 411. In other embodiments, based on the possibility that the fourth positioning hole 313, the fifth positioning hole 323, and the sixth positioning hole 411 can be set as circular holes, a groove can be formed in the hole wall of the circular hole, so that the circular hole and the groove form a continuous irregular hole. The groove and a portion of the circular hole form a rectangular hole. The second limiting part can be set as a cuboid adapted to the rectangular hole. The cross-section of the cuboid perpendicular to the axis of the circular hole is smaller than the cross-section of the rectangular hole perpendicular to the axis of the circular hole. Furthermore, the maximum width of the cross-section of the second handle portion of the second limiting member perpendicular to the axis of the circular hole is greater than the maximum width of the cross-section of the rectangular hole perpendicular to the axis of the circular hole, ensuring that the second handle portion can abut against the upper surface of the first plate 310 or the top edge of the fourth positioning hole 313. In addition, the second limiting part also has a second limiting hole located below the second plate 320 for the fourth connecting member to pass through. The fourth connecting member is used to restrict the upward movement of the second limiting part, ensuring the limiting effect of the second limiting member on the locking plate 400.

[0048] In one possible implementation, the fixing frame 300 further includes a first fixing plate 330 connected to the first plate 310. The first fixing plate 330 has a first contact surface that fits against the first side plate 110. The first contact surface is fixedly connected to the first side plate 110. The fixing connection method can be, but is not limited to, bonding and welding. The second plate 320 is fixedly connected to the first fixing plate 330. The fixing connection method can also be, but is not limited to, bonding and welding. The first plate 310 and the second plate 320 can be fixed simultaneously by only one first fixing plate 330, and the first plate 310 and the second plate 320 are fixed relative to the first side plate 110. This can save material of the fixing frame 300 and reduce production costs.

[0049] In one possible implementation, the fixing frame 300 further includes a first fixing plate 330 connected to the first plate 310 and a second fixing plate 340 connected to the second plate 320. The first plate 310 and the first fixing plate 330 are integrally formed by bending the same plate to improve the structural strength of the first plate 310 and the first fixing plate 330; the second plate 320 and the second fixing plate 340 are integrally formed by bending the same plate to improve the structural strength of the second plate 320 and the second fixing plate 340. The first fixing plate 330 has a first mounting hole 331, the second fixing plate 340 has a second mounting hole 341 coaxial with the first mounting hole 331, and the first side plate 110 has a third mounting hole coaxial with the first mounting hole 331. The second connector passes through the third mounting hole, the first mounting hole 331 and the second mounting hole 341 and is fixed by the second fixing member.

[0050] The first mounting hole 331, the second mounting hole 341, and the third mounting hole correspond one-to-one. The second connecting member can be, but is not limited to, a bolt with a smooth rod and a threaded section. The second fixing member can be, but is not limited to, a nut adapted to the threaded section. Specifically, after the bolt passes through the third mounting hole, the first mounting hole 331, and the second mounting hole 341, the bolt head abuts against the inner side of the first side plate 110. The smooth rod of the bolt extends into the third mounting hole, the first mounting hole 331, and the second mounting hole 341. At least part of the threaded section of the bolt extends to the side of the second fixing plate 340 away from the first fixing plate 330. The nut is fitted onto the threaded section and tightened, so that the first fixing plate 330 and the second fixing plate 340 are fixed relative to the first side plate 110.

[0051] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0052] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0053] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
