Description

Technical Field

[0001] The utility model relates to the technical field of power equipment, in particular to an insulating partition for repairing an isolating switch. Background Art

[0002] Isolators are widely used in power systems, primarily to isolate circuits. When disconnected, they have a clearly visible break. When closed, they allow both normal operating current and short-circuit current in fault conditions to flow through the conductive system. Isolators require regular maintenance during use. During maintenance, the moving and stationary contacts of the isolator must be separated to ensure the safety of maintenance personnel. This separation is typically achieved using an insulating partition.

[0003] In the related art, a flat insulating partition is disclosed. When workers take and place this insulating partition, they may touch the charged body of the disconnector, which is dangerous. To address this problem, in the prior art, the authorized patent document with application number CN201920578967.6 discloses a retractable and foldable insulating partition for maintenance. When in use, this solution can isolate the arms and torso of the maintenance personnel from the charged body by flipping the insulating side panels upward, solving the problem that the insulating partition may touch the charged body during the taking and placing process.

[0027] 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.

[0028] The utility model provides an insulating partition for isolating switch maintenance, comprising a support rod 1, the bottom of which is provided with a clamping sleeve 2 adapted to fit the isolating switch support base. When in use, the insulating partition is fixed in position by clamping the clamping sleeve 2 with the isolating switch support base, preventing movement of the isolating switch during use and improving the reliability of the insulating partition. The clamping sleeve 2 has a U-shaped structure, and the bottom end of the inner cavity of the clamping sleeve 2 is shaped like an eight, which facilitates the clamping sleeve 2 to be clamped to the isolating switch support base.

[0029] The support rod 1 is provided with a placement hole 13 in the middle of its length direction, and a handle 8 is clamped in the inner cavity of the placement hole 13. The handle 8 is movably connected to a fixing rod 17 in the middle of its length direction. A slot 7 adapted to the handle 8 is provided on one side of the bottom end of the support rod 1. When the handle 8 is inserted into the slot 7, the staff can use the handle 8 to drive the support rod 1 to move, and the staff can stay away from the charged body of the isolating switch, avoiding electric shock to the staff due to contact with the charged body of the isolating switch during the process of taking and placing the insulating partition, thereby improving the safety of the insulating partition when in use.

[0030] The top of the support rod 1 is provided with an isolation sleeve adapted to the static contact of the isolating switch on one side, and the isolation sleeve comprises a horizontal plate 4 connected to the support rod 1 and a vertical plate 5 connected to one end of the horizontal plate 4 away from the support rod 1. Both sides of one end of the horizontal plate 4 and both sides of one end of the vertical plate 5 are fixedly connected to a rotating rod. The top of the support rod 1 and the other end of the horizontal plate 4 are fixed with a fixing sleeve movably sleeved with the rotating rod, and the external thread of one fixing sleeve is connected with a bolt, and the middle part of a rotating rod is provided with a threaded hole adapted to the bolt. The horizontal plate 4 is fixedly connected to the support rod 1 by the bolt, and the horizontal plate 4 is fixedly connected to the vertical plate 5 by another bolt. Through the setting of the bolt, when the bolt is threadedly connected to the rotating rod, the horizontal plate 4 and the support rod 1 can be in a fixed connection state, and the vertical plate 5 and the horizontal plate 4 can be in a fixed connection state, thereby fixing the shape of the isolation sleeve, which is convenient for the use of the isolation sleeve; when the bolt is separated from the rotating rod, the horizontal plate 4 and the support rod 1 are in a state of movably connected, and the vertical plate 5 and the horizontal plate 4 are in a state of movably connected, and the isolation sleeve can be folded or unfolded, which is convenient for the storage and assembly of the isolation sleeve. When the insulating partition is in use, the isolation sleeve is L-shaped, and the structure formed by the isolation sleeve and the support rod 1 can isolate the static contact of the disconnector to prevent staff from touching the static contact.

[0031] A positioning block 6 is fixedly connected to the top of the support rod 1, and the bottom of the positioning block 6 is in a horizontal state. The positioning block 6 is located above the horizontal plate 4. Through the setting of the positioning block 6, the positioning block 6 can limit the horizontal plate 4, making it convenient for the staff to quickly unfold the horizontal plate 4.

[0032] The other side of the other end of the support rod 1 is connected to a support plate 3 for supporting the moving contact of the disconnector through a connecting structure. Round rods 14 are fixedly connected to both sides of one end of the support plate 3. The other end of the round rod 14 is movably connected to the support rod 1, and the support plate 3 is movably connected to the support rod 1 through the round rod 14.

[0033] The connecting structure includes a fixed block 18 fixedly connected to the support rod 1, one end of the outer side of the fixed block 18 is movably connected to the driving sprocket 15, the middle part of the driving sprocket 15 is provided with a limiting groove adapted to the handle 8, one end of the outer side of the fixed block 18 is provided with a fixing hole adapted to the fixing rod 17, the other end of the outer side of the fixed block 18 is movably connected to the driven sprocket 9, the driving sprocket 15 and the driven sprocket 9 are connected by a transmission chain 16, the driven sprocket 9 is fixedly connected to the support plate 3 through the round rod 14, the round rod 14 is movably connected to the fixed block 18, and the handle 8 includes a hand-held portion 19 and a limiting portion 20 adapted to the limiting groove; The fixing rod 17 includes a connecting portion 21 movably connected to the inner cavity of the handle 8 and a fixing portion 22 adapted to the fixing hole. The connecting portion 21 and the limiting portion 20 are both non-cylindrical. When the limiting portion 20 is inserted into the limiting groove, the user rotates the handle 8, and the handle 8 can drive the driving sprocket 15 to rotate. The driving sprocket 15 drives the transmission chain 16 engaged therewith to rotate. The transmission chain 16 drives the driven sprocket 9 to rotate. The driven sprocket 9 drives the support plate 3 to rotate via the round rod 14 fixed thereto. The support plate 3 can support the movable contact of the isolating switch to prevent the isolating switch from closing during maintenance. When the fixing portion 22 is inserted into the fixing hole, the position of the fixing rod 17 is fixed, and the position of the handle 8 is fixed, thereby fixing the positions of the driving sprocket 15, the driven sprocket 9, and the support plate 3, making it easier to use the support plate 3.

[0034] In some embodiments of the present application, the gripping portion 19 of the handle 8 is cylindrical, the limiting portion 20 of the handle 8 is rectangular, the connecting portion 21 of the fixing rod 17 is rectangular, and the fixing portion 22 of the fixing rod 17 is a cylindrical rod that is engaged with the fixing hole.

[0035] From the above description, it can be seen that the insulating partition is a foldable structure, which is easy to store. When folded, the handle 8 is inserted into the placement hole 13, the horizontal plate 4 and the support plate 3 are both in a vertical state, and the vertical plate 5 contacts the side of the horizontal plate 4 away from the support rod 1.

[0036] The support rods 1, support plates 3, horizontal plates 4, and vertical plates 5 each include a shaped sleeve 11. The outer surface of the shaped sleeve 11 is wrapped with a protective sleeve 12. A magnet block 10 is fixed to the inner wall of the shaped sleeve 11. The magnet block 10 ensures that when the insulating partition is folded, the various parts are magnetically attracted to each other, preventing them from spreading and facilitating the transfer of the insulating partition. The shaped sleeve 11 can be made of engineering plastic, and the protective sleeve 12 can be made of rubber.

[0037] The insulating partition has insulating properties, and an insulating coating is sprayed on its outer surface. The material of the insulating partition is an insulating material, which can be engineering plastic.

[0038] To sum up: when the insulating partition for isolating switch maintenance is used, the staff rotates the horizontal plate 4 until the horizontal plate 4 is in a horizontal state, and then uses bolts to fix the horizontal plate 4 and the support rod 1 together; the staff then rotates the vertical plate 5 until the vertical plate 5 is in a vertical state, and uses another bolt to fix the horizontal plate 4 and the vertical plate 5 together, and the isolation sleeve is assembled. The staff takes out the handle 8, inserts the handle 8 into the slot 7, and rotates the support plate 3 so that the support plate 3 contacts the top of the support rod 1. After the moving contact and the static contact of the isolating switch are separated, the staff uses the handle 8 to move the insulating partition until the sleeve 2 is engaged with the support base of the isolating switch, and the static contact of the isolating switch is blocked by the isolation sleeve (as shown in the attached manual). Figure 3 (As shown, the disconnector model in the figure is GCD-12KV). The worker removes handle 8, inserts it into the limiting slot, and rotates handle 8. This drives driving sprocket 15, which in turn drives driven sprocket 9 via transmission chain 16. Driven sprocket 9, in turn, drives support plate 3 via round rod 14 fixed to it until support plate 3 supports the disconnector's moving contact. The worker then pushes fixing rod 17 inward until its fixing portion 22 is inserted into the fixing hole, securing support plate 3 in place. The worker can then inspect and repair the disconnector.
