Description

Technical Field

[0001] This utility model relates to the field of outdoor disconnect switch technology, specifically an outdoor disconnect switch that is easy to maintain. Background Technology

[0002] A disconnecting switch is a switching device mainly used for isolating power sources, switching operations, connecting and disconnecting small current circuits, and without arc extinguishing function. Due to its relatively simple operating principle and structure, there are usually no strict regulations on major overhaul cycles. Conventionally, it is usually carried out during the major overhaul of main equipment. It is mainly used to isolate the power supply of distribution lines during maintenance to improve the safety of operation. It has a clear isolation break and is mostly installed on overhead lines and substations.

[0003] For example, the outdoor disconnect switch that is easy to maintain disclosed in the authorization announcement number CN216818191U includes a switch fixing frame. Both sides of the bottom of the switch fixing frame are connected to core rods. Insulating skirts are evenly installed on the outer side of the core rods. A stationary contact is connected to the bottom end of one core rod. A moving contact is arranged in contact with the outer side of the stationary contact. One end of the moving contact is connected to a switch gate, and the end of the switch gate away from the moving contact is movably connected to the inner side of the connecting seat. The connecting seat is fixedly connected to the bottom end of another core rod. Although it enables quick connection between the disconnecting switch and the line connection components during installation via the switch fixing bracket and its end mounting plate, when the disconnecting switch needs to be disassembled, only the fixing pin needs to be removed to release the restriction of the mounting block, so that the mounting block can drive the core rod to slide along the fitting groove. This facilitates the quick removal of the mounting block from the fitting groove, thus eliminating the need to disassemble the entire disconnecting switch from the line connection components when disassembling and maintaining the disconnecting switch. This reduces the convenience of disassembling and assembling the disconnecting switch, while also facilitating better maintenance. However, this does not solve the problem that existing outdoor disconnect switches are generally not conducive to the maintenance and replacement of parts during use, are not convenient for energizing different lines, affect the labor intensity of manual labor, reduce the efficiency of maintenance and replacement of parts, and are not convenient for disassembling and replacing parts. Long-term use may cause poor contact, affecting the stable power supply of the outdoor disconnect switch. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are: the outdoor disconnect switch not only realizes the convenient maintenance and replacement of the components of the outdoor disconnect switch, facilitates the power transmission of different lines, reduces the labor intensity of manual labor, and improves the efficiency of maintenance and replacement of the components of the outdoor disconnect switch, but also realizes the convenient disassembly and replacement of the components of the outdoor disconnect switch, avoids poor contact caused by long-term use, and facilitates the stable power supply of the outdoor disconnect switch. (1) Connect the external power supply to the inlet socket. The inlet socket transmits current to the surface of the main contact blade through the wire. When it is necessary to contact and energize the first stationary contact, the servo motor drives the rotating shaft to rotate. Under the movable support of the support block, the rotating shaft drives the connecting plate and the main contact blade to rotate. The connecting plate limits the main contact blade, so that the main contact blade moves into the interior of the first stationary contact and contacts the two sets of elastic plates. At the same time, the two sets of elastic plates inside the first stationary contact move in opposite directions to generate a thrust. The two sets of first springs inside the first stationary contact provide elastic support for the two sets of elastic plates inside the first stationary contact, thereby pressing the main contact blade to prevent it from loosening and falling off. When it is necessary to contact and energize the second stationary contact, the servo motor drives the rotating shaft to rotate. The rotating shaft drives the connecting plate and the main contact blade to rotate, so that the main contact blade moves. The second stationary contact contacts two sets of elastic plates inside. At the same time, the two sets of elastic plates inside the second stationary contact move in opposite directions, generating a thrust. Under the elastic support of the two sets of first springs inside the second stationary contact, the two sets of first springs inside the second stationary contact provide elastic support for the two sets of elastic plates inside the second stationary contact, thereby clamping the main contact blade. When the inlet socket needs to be maintained or replaced, the first bolt is turned to disengage the first bolt from the first insulator, and the inlet socket can be taken out for maintenance or replacement. When the outlet socket needs to be maintained or replaced, the second bolt is turned to disengage the second bolt from the second insulator. This enables convenient maintenance and replacement of components of the outdoor disconnect switch, facilitates the power transmission of different lines, reduces the labor intensity of manual labor, and improves the efficiency of maintenance and replacement of components of the outdoor disconnect switch. (2) Manually pull the two sets of handles. With the support of the support base, the handles drive the movable shaft to move. The movable shaft drives the second spring and the top block to move, so that the top block is disengaged from the annular groove. The first insulator and the second insulator can be taken out and replaced. When the handle is released, under the elastic support of the second spring, the second spring drives the top block to reset. The new first insulator and the second insulator are placed on the surface of the circular groove inside the support plate, so that the top block is matched with the annular groove and fixed and limited. This realizes the convenient disassembly and replacement of parts of the outdoor disconnect switch, avoids poor contact caused by long-term use, and facilitates the stable power supply of the outdoor disconnect switch.

Under the elastic support of the first stationary contact 18, the two sets of first springs 23 inside the first stationary contact 18 provide elastic support for the two sets of elastic plates 24 inside the first stationary contact 18, thereby pressing the main contact blade 12 tightly to prevent it from loosening and falling off. When it is necessary to make contact and energize the second stationary contact 21, the servo motor 7 drives the rotating shaft 8 to rotate. The rotating shaft 8 drives the connecting plate 13 and the main contact blade 12 to rotate, so that the main contact blade 12 moves into the second stationary contact 21 and makes contact with the two sets of elastic plates 24. At the same time, the two sets of elastic plates 24 inside the second stationary contact 21 move in opposite directions to generate a thrust. Under the elastic support of the two sets of first springs 23 inside the second stationary contact 21, The two sets of first springs 23 inside the second stationary contact 21 provide elastic support for the two sets of elastic plates 24 inside the second stationary contact 21, thereby clamping the main contact blade 12. When maintenance or replacement of the inlet seat 9 is required, the first bolt 14 is tightened, and the first bolt 14 is disengaged from the first insulator 5 due to the threaded connection between the first bolt 14 and the first insulator 5, allowing the inlet seat 9 to be removed for maintenance or replacement. When maintenance or replacement of the outlet seat 15 is required, the second bolt 16 is tightened, and the second bolt 16 is disengaged from the second insulator 6 due to the threaded connection between the second bolt 16 and the second insulator 6, allowing the inlet seat 9 to be removed for maintenance or replacement. When replacing the insulator, manually pull both sets of handles 28. With the support of the support base 27, the handles 28 drive the movable shaft 29 to move. The movable shaft 29 drives the second spring 30 and the top block 32 to move, so that the top block 32 disengages from the annular groove 31, allowing the first insulator 5 and the second insulator 6 to be removed and replaced. When the handles 28 are released, with the elastic support of the second spring 30, the second spring 30 drives the top block 32 to reset, allowing the new first insulator 5 and the second insulator 6 to be placed into the surface of the circular groove 25 inside the support plate 3, so that the top block 32 fits into the annular groove 31 and is fixed in place, thus completing the operation of the outdoor disconnect switch.
