Description

Technical Field

[0001] The utility model relates to the technical field of disconnectors, in particular to a rotary disconnector with an arc path limiting module. Background Art

[0002] An isolating switch is a switching device that is mainly used for isolating power supply, switching operation, connecting and disconnecting low current circuits, and has no arc extinguishing function. However, due to the locking structure of the existing isolating switch, the operation steps required to close the switch when the equipment encounters a circuit breaker are relatively cumbersome, thereby reducing the safety of the equipment when in use. This requires the use of a rotary isolating switch with an arc path limiting module. Therefore, the existing rotary isolating switch with an arc path limiting module has been continuously innovated and developed. Therefore, it can be seen that the current rotary isolating switch basically meets people's needs, but there are still some problems.

[0003] For example, the patent document with the announcement number CN217485343U discloses a contact module and an operating module, wherein the contact module includes a moving contact assembly connected to the operating module, and two groups of static contact assemblies relatively arranged on both sides of the moving contact assembly, the moving contact assembly includes a moving contact bridge and a clamping mechanism arranged at both ends of the moving contact bridge, the clamping mechanism includes an elastic member and two clamping plates respectively matched with the elastic member, the elastic member can drive the two clamping plates close to each other, and the static contact assembly can overcome the action of the elastic member and be inserted between the two clamping plates. By increasing the clamping force between the moving contact bridge and the static contact assembly, the moving contact assembly can be avoided from being burned due to excessive temperature, which is beneficial to extending the service life. By setting the clamping structure and the elastic member, the clamping force between the moving contact bridge and the static contact assembly is increased, which can be avoided from being burned due to excessive temperature, which is beneficial to extending the service life.

[0004] However, when the above-mentioned device increases the clamping force between the moving contact bridge and the static contact assembly, its clamping structure is easily affected when the equipment is short-circuited, and the connection between the moving contact bridge and the static contact is relatively tight. When it is necessary to disconnect them, the operation steps required are relatively cumbersome, thereby reducing the safety of the equipment during use. Therefore, there is an urgent need for a rotary isolating switch with an arc path limiting module to solve the above-mentioned problem. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1 , Figure 4 and Figure 6 A rotary disconnector with an arc path limiting module includes a base 1, two sets of baffles 2 are fixedly connected around the top of the base 1, slots 3 are formed on the inner walls of the baffles 2 on both sides of the top of the base 1, a fixing plate 4 is overlapped on the surface of the baffle 2, and a cover plate 5 is fixedly connected to the top of the fixing plate 4;

[0028] The switch mechanism includes a connecting rod 6, the inner wall of the cover plate 5 is rotatably connected to the connecting rod 6, the top of the connecting rod 6 is fixedly connected to the handle 7, the bottom of the surface of the connecting rod 6 is fixedly connected to the limit block 23, the two sides of the top of the base 1 are fixedly connected to the telescopic rod 8, the inner wall of the telescopic rod 8 is overlapped with the first spring 9, the middle part of the connecting rod 6 is fixedly connected to the connecting assembly 10, and the top of the telescopic rod 8 is overlapped with the bottom of the connecting assembly 10, and the two sides of the connecting assembly 10 are fixedly connected to the first copper sheet 11.

[0029] When using a rotary isolating switch with an arc path limiting module, it is necessary to install the device in the working position, and then fix the cover plate 5 to the surface of the baffle 2 through the fixing plate 4 at the bottom, so that the cover plate 5 and the internal structure are installed on the top of the base 1, and then connect the power supply on both sides of the device, and rotate the handle 7 to drive the connecting rod 6 at the bottom to rotate. The rotation of the connecting rod 6 drives the connecting components 10 and the first copper sheet 11 on both sides to move around the axis of the connecting rod 6. When the first copper sheet 11 is rotated to the position where the cable is fixed, the first copper sheet 11 connects the two. When the switch needs to be turned off, the handle 7 is turned to drive the connecting rod 6 to rotate. When the connecting rod 6 rotates, the first spring 9 pushes the telescopic rod 8 to fit into the bottom of the connecting assembly 10, thereby providing a certain resistance to the handle 7. After the applied force is greater than the resistance, the connecting assembly 10 moves away from the surface of the telescopic rod 8 and moves to the switch-off position. At this time, another set of first springs 9 pushes the telescopic rod 8 to fit into the bottom of the connecting assembly 10, thereby fixing the connecting assembly 10 again and completing the closing of the switch.

[0030] See also Figure 2 , Figure 3 and Figure 7The inner wall of the fixed plate 4 is slidably connected with a card block 12, one side of the card block 12 is fixedly connected with a push plate 13, a second spring 14 is provided on one side of the card block 12, and the surface of the card block 12 is overlapped with the inner wall of the card slot 3, an indicator groove 15 is opened on the top of the cover plate 5, and gaskets 16 are fixedly connected around the surface of the base 1.

[0031] Before installing the equipment, first place the base 1 to the installation position, then use bolts and gaskets 16 to fix the base 1 to the installation position, then push the push plate 13 to make the block 12 move relatively and be received in the fixed plate 4, then insert the fixed plate 4 at the bottom of the cover plate 5 into the surface of the baffle 2, then release the push plate 13, and push the block 12 to move through the second spring 14, so that it is stuck in the slot 3 on the inner wall of the baffle 2, thereby fixing the fixed plate 4 and the cover plate 5 to the top of the baffle 2.

[0032] See also Figure 1 , Figure 3 and Figure 5 The inner walls of the baffle 2 and the fixed plate 4 are both provided with a threaded groove 17, the inner wall of the threaded groove 17 is threadedly connected to a threaded block 18, one side of the threaded block 18 is fixedly connected to a wire tube 19, and the other side of the threaded block 18 is fixedly connected to a second copper sheet 20. The surface of the threaded block 18 is threadedly connected with fixing bolts 21 around the periphery, and the surface of the threaded block 18 is located on both sides of the top of the base 1.

[0033] When installing the cable, first insert the cable into the wire tube 19, then rotate the fixing bolts 21. The four sets of fixing bolts 21 fix the cable to the middle of the wire tube 19 by rotating. The fixing bolts 21 are made of plastic and are non-conductive. Then rotate the thread block 18 through the thread groove 17 to the inner wall of the baffle 2 and the fixing plate 4, so that the second copper sheet 20 is located inside the equipment.

[0034] See also Figure 2 and Figure 4 A rotation groove 22 is provided in the middle of the top of the base 1, and the bottom end of the connecting rod 6 is rotatably connected to the inner wall of the rotation groove 22. The cross-section of the top of the telescopic rod 8 is semicircular, and the bottom of the connecting component 10 is provided with a groove corresponding to the semicircular shape.

[0035] The connecting rod 6 and the limiting block 23 both rotate in the rotation groove 22 , and the rotation groove 22 can limit the maximum movable position of the limiting block 23 , thereby limiting the maximum rotation angle of the handle 7 .

[0036] Working principle: when using a rotary disconnector with an arc path limiting module, first install the base 1 to the working position with bolts, then insert the block 12 into the slot 3 in the baffle 2, and then insert the cable into the wire tube 19 to fix the cable, and fix it to both sides of the equipment through the threaded block 18, and then rotate the first copper sheet 11 on both sides of the connecting component 10 to the side of the second copper sheet 20. At this time, the current of the cable is guided to the first copper sheet 11 through the second copper sheet 20, and then guided to another group of cables and the second copper sheet 20 through the first copper sheet 11, thereby turning on the power. When the switch needs to be turned off, turn the handle 7 to drive the connecting rod 6 to rotate, and move the first copper sheet 11 away from the side of the second copper sheet 20. At this time, the first spring 9 pushes the telescopic rod 8 to be stuck in the bottom of the connecting component 10, thereby fixing the connecting component 10, thereby completing the closing of the switch.
