Description

Technical Field

[0001] The present invention relates to the technical field of isolating switches, and more particularly to an outdoor high-voltage isolating switch. Background Art

[0002] High-voltage disconnectors are important switchgear in the electrical systems of power plants and substations, and must be used in conjunction with high-voltage circuit breakers. Disconnectors are suitable for indoor installations with three-phase AC 50Hz and rated voltage 12KV. They are used to connect, disconnect or convert lines when there is voltage but no load on high-voltage equipment. Its main functions are: to ensure the safety of high-voltage electrical appliances and devices during maintenance work, to isolate voltage, and cannot be used to cut off, put in load current or break short-circuit current. It can only be used for certain switching operations that do not generate strong arcs, that is, it does not have an arc extinguishing function; according to the installation location, it can be divided into indoor and outdoor types.

[0003] When the existing high-voltage disconnector is in use, it is rotatably connected to the electrical contact on one side through a switch blade. When the switch blade rotates to clamp the electrical contact on the other side, the disconnector is closed to connect the entire circuit. When the switch blade rotates to separate from the electrical contact on the other side, the disconnector is opened to disconnect the entire circuit. However, when the disconnector is in use, the electrical contact is clamped by the switch blade. Although the stability of the closing is ensured, the switch blade will be deformed and worn after long-term use, making it impossible for the switch blade to stably clamp the electrical contact, thereby reducing the stability of the disconnector after closing.

[0040] The T-shaped slide groove 51 is slidably connected with a T-shaped slider 52, and the upper surface of the T-shaped slider 52 is fixedly connected with a fixed clamp 53. A mounting plate 55 is provided on the upper surface of the fixed block 3 on one side, and the No. 1 electrical contact head 9 and the fixed clamp 53 both penetrate the upper surface of the mounting plate 55. Limiting clamps 56 are fixedly connected to the positions near the fixed clamp 53 on both sides of the upper surface of the mounting plate 55, and the outer surface of the limiting clamp 56 is provided with a No. 1 groove 57 at the lower end of the side close to each other.

[0041] like Figure 1 As shown, the insulator 2, the fixed block 3 and the switch blade 11 are each provided with two, and the two switch blades 11 are located on both sides of the No. 1 electrical contact head 9, the two fixed clamping plates 53 are located on both sides of the two switch blades 11, and the two limiting clamping plates 56 are located on both sides of the two fixed clamping plates 53. The inner side of the two switch blades 11 close to the No. 1 electrical contact head 9 is fixedly connected with a pull ring 12, and the lower ends of the outer surfaces of the two fixed blocks 3 away from each other are fixedly connected with the terminal board 4.

[0042] like Figure 4 As shown, the outer surfaces of the two fixing clamps 53 are fixedly connected to one side away from each other with evenly distributed triangular support blocks 58 , and the triangular support blocks 58 are fixedly connected to the upper surface of the mounting plate 55 .

[0043] like Figure 2 , Figure 3 , Figure 4 As shown, one side of the outer surface of the two fixed clamps 53 is provided with a through groove 54, and the mounting plate 55 passes through the through groove 54 and is slidably connected to the through groove 54, and the lower surface of the mounting plate 55 is fixedly connected with four rectangular and evenly distributed positioning cylinders 510, and one side of the upper surface of the fixed block 3 corresponding to the four positioning cylinders 510 is provided with positioning holes 59, and the four positioning cylinders 510 are respectively slidably connected to the inside of the four positioning holes 59, and the four positioning cylinders 510 are each provided with a No. 1 spring 511.

[0044] When in use, the isolating switch is installed on the electric pole through the mounting frame 1, and then the wires are connected through the terminal board 4 on one side of the fixing block 3. The wires on one side are connected to the distribution cabinet, and the wires on the other side are directly connected to the power grid. At the same time, the high-voltage power supply and the ground are isolated by the insulator 2 to prevent the current from being directly grounded. Then, the pull ring 12 can drive the switch blade 11 to rotate around the No. 2 electrical contact head 10. When the switch blade 11 rotates to contact the No. 1 electrical contact head 9, the No. 1 electrical contact head 9 is clamped to complete the closing. However, long-term use will cause deformation and wear of the switch blade 11, making it impossible for the switch blade 11 to stably clamp the electrical contact, thereby reducing the stability of the isolating switch after closing. Therefore, the clamping assembly 5 is provided, and when the switch is closed, the mounting plate 55 is simultaneously driven to move downward, thereby driving the two limiting clamps 56 to move downward, and then the two fixed clamps 53 are driven to move closer to each other through the provision of the No. 1 groove 57, thereby pushing the two gate blades 11 to clamp the No. 1 electrical contact head 9, thereby ensuring the stability of the two gate blades 11 clamping the No. 1 electrical contact head 9, and improving the stability of the disconnector after closing. After the switch is opened, the mounting plate 55 is driven to move upward by the No. 1 spring 511, so that the mounting plate 55 can be automatically reset, and the sliding connection between the positioning cylinder 510 and the positioning hole 59 ensures the stability of the movement of the mounting plate 55, and at the same time, the sliding connection between the mounting plate 55 and the through groove 54 limits the movement of the mounting plate 55 to prevent the mounting plate 55 from being separated from the fixed clamp 53.

[0045] like Figure 2 , Figure 5 , Figure 6 As shown, a fixing component 6 is arranged between the mounting plate 55 and the fixing block 3, and the fixing component 6 includes a No. 1 mounting groove 61 provided on one side of the upper surface of the fixing block 3 close to the pull ring 12, a No. 1 slide plate 62 is slidably connected inside the No. 1 mounting groove 61, a No. 1 L-shaped block 63 is fixedly connected to one side of the upper surface of the No. 1 slide plate 62, a No. 2 L-shaped block 64 is fixedly connected to a position corresponding to the No. 1 mounting groove 61 on the lower surface of the mounting plate 55, a No. 1 slide groove 65 is provided on the side of the inner wall of the No. 1 mounting groove 61 away from the No. 1 L-shaped block 63, a No. 2 slide plate 66 is slidably connected inside the No. 1 slide groove 65, two No. 1 straight rods 67 are fixedly connected between the No. 2 slide plate 66 and the No. 1 slide plate 62, and No. 2 springs 68 are provided on the outer circumferential surfaces of the two No. 1 straight rods 67.

[0046] like Figure 5 , Figure 6As shown, one end of the two No. 1 straight rods 67 penetrates the No. 2 slide plate 66 and the outer surface of the fixed block 3, and one end of the two No. 1 straight rods 67 is commonly connected to a connecting rod 69, and a fixing plate 610 is fixedly connected to the lower side of the outer surface of the fixing plate 610 near the connecting rod 69. A triangular protrusion 611 is fixedly connected to the lower side of the outer surface of the fixing plate 610 near the connecting rod 69.

[0047] In the above embodiment, the two limiting clamps 56 are used to drive the two fixing clamps 53 to move closer to each other, thereby pushing the two switch blades 11 to clamp the No. 1 electrical contact 9. However, when the mounting plate 55 moves downward, the No. 1 spring 511 is compressed, so that the No. 1 spring 511 has upward elastic potential energy, which will push the mounting plate 55 to move upward, and then push the switch blade 11 to rotate upward, so that the switch blade 11 is separated from the No. 1 electrical contact 9, reducing the stability of the isolating switch after closing. Therefore, a fixing assembly 6 is provided, and when the mounting plate 55 moves downward, the second L-shaped block 64 is driven to move downward, so that the second L-shaped block 64 moves into the first mounting groove 61, and then the second slide plate 66 is driven by the second spring 68 to move in the first slide groove 65 in a direction away from the first mounting groove 61, and at the same time, the first slide plate 62 is driven to move by the first straight rod 67, thereby driving the first L-shaped block 63 to move toward the second L-shaped block 64, so that the first L-shaped block 63 is engaged with the second L-shaped block 64, thereby fixing the second L-shaped block 64 in the first mounting groove 61, and then fixing the mounting plate 55 to prevent the mounting plate 55 from moving, thereby preventing the mounting plate 55 from moving. The plate 55 pushes the blade 11 to rotate upward, so that the blade 11 is separated from the No. 1 electrical contact head 9, thereby improving the stability of the disconnector after closing. When opening, it also drives the fixed plate 610 to rotate, thereby driving the triangular protrusion 611 to rotate, thereby pushing the connecting rod 69 to move in the direction of the fixed block 3, and then drives the No. 1 slide plate 62 to move through the No. 1 straight rod 67, thereby driving the No. 1 L-shaped block 63 to move away from the No. 2 L-shaped block 64, so that the No. 1 L-shaped block 63 is separated from the No. 2 L-shaped block 64, releasing the fixation of the No. 2 L-shaped block 64, thereby releasing the fixation of the mounting plate 55, thereby facilitating the resetting of the mounting plate 55.

[0048] like Figure 3 , Figure 7 , Figure 8As shown, a blocking assembly 7 is arranged inside the two fixed splints 53, and the blocking assembly 7 includes a No. 2 mounting groove 71 on the upper end of the outer surface of the fixed splint 53 close to the gate blade 11, and the interior of the two No. 2 mounting grooves 71 is rotatably connected with a rotating baffle 72, and No. 2 slide grooves 75 are provided on both sides of the lower end of the inner wall of the No. 2 mounting groove 71 away from the gate blade 11, and the interior of the two No. 2 slide grooves 75 is slidably connected with a No. 1 straight plate 77, and the lower ends of the two No. 1 straight plates 77 are fixedly connected with a slider 76, and the lower ends of the two No. 2 slide grooves 75 are provided with a No. 3 mounting groove 73, and one side of the two No. 3 mounting grooves 73 passes through the outer surface of the fixed splint 53 close to the limiting splint 56, and the two No. 3 mounting grooves 73 are located on both sides of the through groove 54, and the interior of the two No. 3 mounting grooves 73 is rotatably connected with a rotating plate 74, and the slider 76 is located above the rotating plate 74.

[0049] like Figure 8 As shown, a No. 2 groove 78 is provided at a position on the outer surface of the rotating baffle 72 opposite to the upper ends of the two No. 1 straight plates 77, and a No. 3 slide groove 79 is provided on both sides of the inner walls of the two No. 2 grooves 78. The upper ends of both sides of the outer surface of the No. 1 straight plate 77 are fixedly connected with a No. 2 straight rod 710, and the two No. 2 straight rods 710 are slidably connected to the inside of the two No. 3 slide grooves 79 respectively.

[0050] In the above embodiment, although the two gate blades 11 are clamped with the No. 1 electrical contact head 9 by the two fixed clamping plates 53, after long-term use, in weather such as strong winds, the gate blades 11 will still be separated from the two fixed clamping plates 53, reducing the stability of the isolating switch after closing. Therefore, a blocking component 7 is provided, and the mounting plate 55 drives the two limiting clamping plates 56 to move downward, so that the two No. 1 grooves 57 move downward, thereby pushing the rotating plate 74 to rotate in the No. 3 mounting groove 73, and then driving the slider 76 to move upward in the No. 2 slide groove 75, while driving the No. 1 straight plate 77 to move upward, and then through the sliding connection between the No. 2 straight rod 710 and the No. 3 slide groove 79, the rotating baffle plate 72 can be pushed to rotate in the No. 2 mounting groove 71, so that the rotating baffle plate 72 is vertical to the fixed clamping plate 53, thereby blocking the gate blade 11 from rotating through the rotating baffle plate 72, so that the gate blade 11 cannot be separated from the clamping of the two fixed clamping plates 53, further improving the stability of the isolating switch after closing.

[0051] like Figure 8 , Fig. 9 , Fig.10As shown, a reset component 8 is arranged between the through groove 54 and the No. 2 mounting groove 71, and the reset component 8 includes a No. 4 slide groove 81 opened on one side of the middle position of the lower end of the inner wall of the No. 2 mounting groove 71 close to the gate blade 11, and a No. 3 slide plate 82 is slidably connected inside the No. 4 slide groove 81, and a No. 2 straight plate 83 is fixedly connected to the upper surface of the No. 3 slide plate 82, and three evenly distributed No. 3 straight rods 84 are fixedly connected to the lower surface of the No. 3 slide plate 82, and the No. 3 straight rods 84 pass through the upper end of the inner wall of the through groove 54.

[0052] like Fig.10 As shown, a No. 5 slide groove 85 is provided at the position corresponding to the three No. 3 straight rods 84 at the upper end of the inner wall of the through groove 54, a No. 4 slide plate 86 is slidably connected inside the No. 5 slide groove 85, and the three No. 3 straight rods 84 are fixedly connected to the No. 4 slide plate 86, and a No. 3 spring 87 is provided on the outer circumferential surface of the three No. 3 straight rods 84 near the No. 4 slide plate 86.

[0053] In the above embodiment, by pushing the rotating plate 74 to rotate, the rotating baffle 72 is driven to rotate, so that the rotating baffle 72 is in a vertical state with the fixed clamping plate 53, and the gate blade 11 is blocked by the rotating baffle 72 to prevent the gate blade 11 from being separated from the clamping of the two fixed clamping plates 53. However, after the disconnector is opened, because the rotating baffle 72 rotates in the second mounting groove 71, the rotating baffle 72 is easy to rotate automatically, resulting in that when closing the switch, the rotating baffle 72 is easy to block the gate blade 11 from closing the switch. Therefore, a reset component 8 is provided. After opening the switch, the mounting plate 55 automatically moves upward, and the mounting plate 55 is installed. The mounting plate 55 moves in the through slot 54, so that after the mounting plate 55 is reset, the fourth slide plate 86 is pushed to move upward in the fifth slide slot 85, and then the third slide plate 82 is pushed to move upward in the fourth slide slot 81 through the third straight rod 84, and the second straight plate 83 is pushed upward, thereby pushing the rotating baffle 72 to rotate upward, so that the rotating baffle 72 and the fixed clamping plate 53 are approximately in the same line, thereby effectively preventing the rotating baffle 72 from rotating automatically, and preventing the rotating baffle 72 from blocking the gate blade 11 from closing when the isolating switch is closed, thereby facilitating the closing of the gate blade 11.

[0054] Method of use: install the isolating switch on the electric pole through the mounting frame 1, then connect the wires through the terminal block 4 on one side of the fixing block 3, and then drive the switch blade 11 to rotate around the No. 2 electrical contact head 10 toward the No. 1 electrical contact head 9 through the pull ring 12, so that the No. 1 electrical contact head 9 is clamped, and at the same time, the mounting plate 55 is pushed downward, and then the clamping component 5 is used to drive the two fixed clamping plates 53 to push the two switch blades 11 to clamp the No. 1 electrical contact head 9, and then start the blocking component 7 to drive the rotating baffle 72 to rotate, so that the rotating baffle 72 is perpendicular to the fixed clamping plate 53, and finally the No. 2 is clamped through the fixing component 6. The L-shaped block 64 is fixed into the No. 1 mounting groove 61, thereby fixing the mounting plate 55. When opening the gate, the pull ring 12 drives the gate blade 11 to rotate away from the No. 1 electrical contact head 9. At the same time, the fixing assembly 6 is driven by the fixing plate 610 and the triangular protrusion 611 to release the fixation of the No. 2 L-shaped block 64. Then, the mounting plate 55 is driven to move upward through the No. 1 spring 511. At the same time, the mounting plate 55 slides in the through groove 54, pushing the No. 4 slide plate 86 to move upward, thereby starting the reset assembly 8 and driving the rotating baffle 72 to rotate upward, so that the rotating baffle 72 and the fixed clamping plate 53 are in a state of being approximately colinear.
