Description

Technical Field

[0001] This utility model relates to the field of high voltage technology, and in particular to a disconnecting switch for high voltage. Background Technology

[0002] High-voltage disconnect switches are crucial switching devices in power systems, primarily used for voltage isolation to ensure equipment safety. They are typically used in conjunction with high-voltage circuit breakers, playing a critical role in the electrical systems of power plants and substations. Suitable for three-phase AC systems, they have high rated voltages, such as 12kV or higher. The main function of these disconnect switches is to ensure the safety of high-voltage electrical equipment and devices during maintenance work by preventing current flow through voltage isolation, thereby ensuring the safety of maintenance personnel. It is important to note that high-voltage disconnect switches do not have arc-extinguishing capabilities and therefore cannot be used to interrupt load current or short-circuit current. High-voltage disconnect switches can be classified in several ways. Based on installation location, they can be divided into indoor and outdoor types; based on the number of insulating supports, they can be divided into single-pole, double-pole, and three-pole types.

[0003] In existing high-voltage disconnect switches, the length of the disconnect switch is mostly fixed. However, the required length of the disconnect switch varies depending on different installation requirements. Furthermore, the contact style of the disconnect switch is also different depending on the voltage transmission. However, the contacts of existing disconnect switches are mostly fixedly connected to the disconnect switch and the contact style cannot be changed. Therefore, this needs to be improved.

[0057] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a high-voltage disconnecting switch.

[0058] A disconnecting switch for high voltage includes a support plate 1 and a support shaft 2, the support shaft 2 being rotatably connected to the support plate 1; it also includes: a support column 3, disposed on the support shaft 2 and fixedly connected to the support shaft 2; a coil 4, disposed on the support column 3 and detachably fixedly connected to the support column 3; a support frame 5, disposed on the support shaft 2 and fixedly connected to the support shaft 2; a telescopic mechanism disposed within the support frame 5 for adjusting the length of the disconnecting switch; and a clamping mechanism disposed on the telescopic mechanism for replacing the contacts.

[0059] Reference Figure 4 In a preferred embodiment, the telescopic mechanism includes: a telescopic cylinder 6, which is disposed within the support frame 5 and fixedly connected to the support frame 5; a telescopic rod 7, which is slidably connected to the telescopic cylinder 6; and a sliding component, which is disposed within the support frame 5.

[0060] This configuration ensures that when the telescopic cylinder 6 is in operation, it drives the telescopic rod 7, which is slidably connected to the telescopic cylinder 6, to slide away from the telescopic cylinder 6, thereby driving the sliding component to operate.

[0061] Reference Figure 3 and Figure 4 In a preferred embodiment, the sliding component includes: a sliding groove 8, which is formed within the support frame 5; a sliding block 9, which is disposed within the sliding groove 8, slidably connected to the sliding groove 8, and fixedly connected to the telescopic rod 7; a sliding rod 10, which is disposed on the sliding block 9 and fixedly connected to the sliding block 9; and a connecting component, which is disposed on the sliding block 9.

[0062] This configuration allows the sliding block 9, which is fixedly connected to the telescopic rod 7, to slide within the sliding groove 8, thereby moving the sliding rod 10, which is fixedly connected to the sliding block 9, and causing the connecting components to operate.

[0063] Reference Figure 4 In a preferred embodiment, the connecting component includes: a plurality of first connecting shafts 11, which are evenly arranged on the sliding block 9 and fixedly connected to the sliding block 9; a first connecting plate 12, which is rotatably connected to the first connecting shafts 11; a second connecting shaft 13, which is rotatably connected to the first connecting plate 12; a second connecting plate 14, which is rotatably connected to the second connecting shaft 13; and a third connecting shaft 15, which is disposed on the second connecting plate 14, rotatably connected to the second connecting plate 14, and fixedly connected to the support frame 5.

[0064] This configuration allows the first connecting plate 12, which is rotatably connected to the first connecting shaft 11, to rotate, thereby causing the second connecting plate 14, which is rotatably connected to the second connecting shaft 13, to rotate around the axis of the third connecting shaft 15, thus enabling the adjustment of the length of the disconnecting switch.

[0065] Reference Figure 5 In a preferred embodiment, the clamping mechanism includes: a clamping frame 16, disposed on the sliding rod 10 and fixedly connected to the sliding rod 10; a clamping cylinder 17, disposed inside the clamping frame 16 and fixedly connected to the clamping frame 16; a clamping rod 18, slidably connected to the clamping cylinder 17; a clamping block 19, disposed on the clamping rod 18 and fixedly connected to the clamping rod 18; and a rotating component, disposed on the clamping block 19.

[0066] This configuration causes the clamping cylinder 17 to slide away from the clamping cylinder 17 when it is in operation, causing the clamping rod 18, which is slidably connected to the clamping cylinder 17, to move away from the clamping cylinder 17, thereby moving the clamping block 19, which is fixedly connected to the clamping rod 18, and driving the rotating component to run.

[0067] Reference Figure 5 In a preferred embodiment, the rotating component includes: a plurality of first rotating shafts 20, which are evenly arranged on the clamping block 19 and fixedly connected to the clamping block 19; a rotating plate 21, which is disposed on the first rotating shafts 20 and rotatably connected to the first rotating shafts 20; a second rotating shaft 22, which is rotatably connected to the rotating plate 21; and a transmission component, which is disposed on the clamping frame 16.

[0068] This configuration allows the rotating plate 21, which is rotatably connected to the first rotating shaft 20, to rotate, thereby driving the transmission components to operate.

[0069] Reference Figure 5In a preferred embodiment, the transmission component includes: a transmission groove 23, which is formed on the clamping frame 16; multiple transmission blocks 24, which are evenly arranged in the transmission groove 23, slidably connected to the transmission groove 23, and fixedly connected to the second rotating shaft 22; a transmission plate 25, which is disposed on the transmission blocks 24 and fixedly connected to the transmission blocks 24; and a transmission rod 26, which is fixedly connected to the transmission plate 25.

[0070] This configuration allows the transmission block 24, which is fixedly connected to the second rotating shaft 22, to slide within the transmission groove 23, causing the transmission plates 25, which are fixedly connected to the transmission block 24, to move closer together, and causing the transmission rods 26, which are fixedly connected to the transmission plates 25, to move until the transmission rods 26 come into contact with each other, thereby fixing the contact.

[0071] Working principle: When adjusting the length, the telescopic cylinder 6 is activated, which drives the telescopic rod 7, which is slidably connected to the telescopic cylinder 6, to slide away from the telescopic cylinder 6. This causes the sliding block 9, which is fixedly connected to the telescopic rod 7, to slide in the sliding groove 8, which in turn moves the sliding rod 10, which is fixedly connected to the sliding block 9. This causes the first connecting plate 12, which is rotatably connected to the first connecting shaft 11, to rotate. This causes the second connecting plate 14, which is rotatably connected to the second connecting shaft 13, to rotate around the axis of the third connecting shaft 15, thereby adjusting the length of the disconnect switch.

[0072] Then, when the contact needs to be replaced, the clamping cylinder 17 is activated, which drives the clamping rod 18, which is slidably connected to the clamping cylinder 17, to slide away from the clamping cylinder 17. This causes the clamping block 19, which is fixedly connected to the clamping rod 18, to move, thereby causing the rotating plate 21, which is rotatably connected to the first rotating shaft 20, to rotate. This causes the transmission block 24, which is fixedly connected to the second rotating shaft 22, to slide in the transmission groove 23. This causes the transmission plate 25, which is fixedly connected to the transmission block 24, to move closer to each other, and causes the transmission rod 26, which is fixedly connected to the transmission plate 25, to move until the transmission rods 26 contact each other, thereby fixing the contact.

[0073] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
