Technical Field

[0001] The invention belongs to the field of outdoor pole switches, and in particular relates to a primary-secondary fused sealed pole and a power taking device used on an outdoor pole. Background Art

[0002] The primary and secondary fused sealed pole is a kind of power equipment component that integrates multiple functions. It is mainly used in outdoor pole-mounted vacuum circuit breakers and other equipment in power systems. The primary and secondary fused sealed pole refers to the vacuum interrupter, phase sequence and zero sequence current sensor, phase sequence and zero sequence voltage sensor and other components, which are encapsulated into an independent component through solid insulating materials.

[0003] Most of the existing primary and secondary fused sealed poles are fixed to the mechanism box by screws, and in order to prevent the screws from being rusted by rainwater, the screws are usually arranged inside the mechanism box, so that when replacing the sealed poles, the mechanism box usually needs to be disassembled, which is troublesome.

[0004] The power extraction device is a technical product that uses the principle of electromagnetic induction to obtain electrical energy from high-voltage transmission lines. It is often used in vacuum circuit breakers to provide electrical energy for the components inside the vacuum circuit breakers.

[0035] When installing the sealed pole body 1, align the positioning column 62 with the opening of the L-shaped groove 63 and put it into the fixing tube 61, then rotate the sealed pole body 1 along the L-shaped groove 63 until the positioning column 62 touches the end of the L-shaped groove 63, use a screwdriver to rotate the adjusting nut 76, the adjusting nut 76 drives the worm 75 to rotate, the worm 75 drives the worm wheel 72 and the screw 73 to rotate, the screw 73 drives the locking block 77 to descend, so that the locking block 77 extends into the L-shaped groove 63, the locking block 77 fixes the positioning column 62 in the L-shaped groove 63, when disassembling, only need to rotate the adjusting nut 76 in the opposite direction, and then rotate the sealed pole body 1 in the opposite direction, the sealed pole body 1 can be removed from the mechanism box 2, the operation is simple and convenient.

[0036] like Figure 5-Figure 11 As shown, a power taking device for outdoor poles provided by the present invention is provided. In order to facilitate the disassembly and replacement of the power taking device, in this embodiment, a power taking component 3 is included. The power taking component 3 includes a mounting sleeve 34 and a mounting groove 32. The mounting groove 32 is provided on the side of the sealed pole body 1. The axis of the mounting groove 32 coincides with the axis of the lower outlet terminal 5. The mounting sleeve 34 is threadedly connected to the mounting groove 32. A through hole is provided on the mounting sleeve 34 for the lower outlet terminal 5 to pass through. A clamping mechanism 39 is fixedly installed inside the mounting sleeve 34. A magnetic core 37 is installed on the clamping mechanism 39. The magnetic core 37 is provided with a magnetic core 37. An insulating tube 38 is fixedly installed on the side near the installation groove 32, and the magnetic core 37 and the insulating tube 38 are electrically connected through a connecting wire 36. Two second electrode sheets 35 are electrically connected to the side of the insulating tube 38. Two first electrode sheets 33 adapted to the two second electrode sheets 35 are fixedly connected on the inner side wall of the installation groove 32. When the installation sleeve 34 is installed on the sealed pole body 1, the two second electrode sheets 35 are respectively in contact with the two first electrode sheets 33. The sealed pole body 1 is provided with a power outlet terminal 31, and the live wire and the neutral wire of the power outlet terminal 31 are respectively electrically connected to the two first electrode sheets 33.

[0037] like Figure 6-Figure 9 , Fig.11 As shown, a power extraction device for outdoor poles provided by the present invention is provided. In this embodiment, the clamping mechanism 39 includes a base plate 391, and the base plate 391 is fixedly installed inside the mounting sleeve 34. A plurality of evenly distributed mounting seats 392 are fixedly connected to the side of the base plate 391. A rotating seat 393 is hinged on the mounting seat 392. A clamping rod 394 is installed at one end of the rotating seat 393. A hook is provided at the end of the clamping rod 394 so that it can clamp the magnetic core 37. A toggle rod 395 is fixedly connected to the side of the rotating seat 393 facing the center of the base plate 391. A placement plate 397 is connected to the side of the base plate 391 through a first compression spring 396. The surface of the placement plate 397 contacts the end of the toggle rod 395. Initially, the rotating seat 393 is inclined relative to the vertical plane, and a plurality of movable grooves 399 adapted to the rotating seat 393 are provided on the placement plate 397.

[0038] Initially, the multiple clamping rods 394 are in an open state, and the distance between the ends of the multiple clamping rods 394 is greater than the diameter of the magnetic core 37. Therefore, when replacing the magnetic core 37, the magnetic core 37 can be directly pressed between the multiple clamping rods 394, and the magnetic core 37 drives the placement plate 397 to descend. The placement plate 397 drives the rotating seat 393 to rotate through the toggle rod 395, and the rotating seat 393 drives the clamping rods 394 to clamp the magnetic core 37.

[0039] In order to avoid affecting the replacement of the magnetic core 37, the toggle rod 395 can be set to an elastic structure. When the magnetic core 37 has not fully entered the clamping rod 394, the toggle rod 395 will be deformed under the squeezing of the placement plate 397. When the magnetic core 37 fully enters the clamping rod 394, the toggle rod 395 returns to its original state and clamps the magnetic core 37 on the clamping rod 394 through the placement plate 397.

[0040] like Figure 7-Figure 8As shown, a power-taking device for use on an outdoor pole provided by the present invention is provided. Since the bending degree of the elastic material is limited, when installing the magnetic core 37, when the staff accidentally presses excessively and causes the bending degree of the toggle rod 395 to exceed its limit, the toggle rod 395 is likely to break, affecting the use of the clamping mechanism 39. Therefore, in this embodiment, the toggle rod 395 is configured as a telescopic rod, and the toggle rod 395 includes a fixed oblique rod 3951 fixedly connected to the side of the rotating seat 393, and the end of the fixed oblique rod 3951 is provided with a receiving groove 3953, and the interior of the receiving groove 3953 is slidably connected with a movable column 3954, and a third compression spring 3952 is connected between the movable column 3954 and the fixed oblique rod 3951, and the end of the movable column 3954 abuts against the side of the placement plate 397.

[0041] When the placing plate 397 squeezes the toggle rod 395 , the third compression spring 3952 is compressed and deformed, and the third compression spring 3952 is not easily damaged, which can reduce the failure rate of the clamping mechanism 39 .

[0042] like Figure 7-Figure 9 As shown, it is a power taking device used on an outdoor pole provided by the present invention. When the magnet core 37 is installed, when the magnet core 37 has not completely fallen into the clamping rod 394, the end of the clamping rod 394 will contact the peripheral side wall of the magnet core 37. Since the contact area between the hook and the peripheral side wall of the magnet core 37 is small, the pressure of the clamping rod 394 on the peripheral side wall of the magnet core 37 is large, which is easy to cause damage to the peripheral side wall of the magnet core 37. Therefore, in this embodiment, one end of the rotating seat 393 is slidably connected to the clamping rod 394, and a second compression spring 398 is connected between the rotating seat 393 and the clamping rod 394. The clamping mechanism 39 also includes a delay mechanism 9, which includes a movable hole 94 opened on the clamping rod 394, a positioning block 95 is slidably connected inside the movable hole 94, and the length of the positioning block 95 is the same as the width of the clamping rod 394. The side of the rotating seat 393 away from the center of the bottom plate 391 is fixedly connected to a mounting tube 91, and the mounting tube 91 is connected to the inside of the rotating seat 393. The inside of the mounting tube 91 is slidably connected to a top column 93, and the top column 93 and the mounting tube 91 are connected to each other. A fourth compression spring 92 is connected between the mounting round tubes 91, a mounting square tube 96 is fixedly connected to the side of the rotating seat 393 near the center of the bottom plate 391, the mounting square tube 96 is connected to the inside of the rotating seat 393, a push-back block 97 is slidably connected to the inside of the mounting square tube 96, the center line of the push-back block 97 coincides with the axis of the top column 93, when the positioning block 95 is inserted into the mounting square tube 96, the distance from the end of the clamping rod 394 to the surface of the placement plate 397 is greater than the thickness of the magnet core 37; The clamping rod 394 is pulled upward, and the clamping rod 394 drives the positioning block 95 to rise. When the center line of the positioning block 95 coincides with the center line of the top column 93, under the action of the fourth compression spring 92, the top column 93 pushes the positioning block 95 to move, and one end of the positioning block 95 is inserted into the mounting square tube 96, and pushes the push-back block 97 to move, so that the clamping rod 394 is fixed on the rotating seat 393 through the positioning block 95; when the placing plate 397 descends, the movable groove 399 squeezes the push-back block 97 and pushes the push-back block 97 to move in the opposite direction, and the push-back block 97 pushes the positioning block 95 back into the movable hole 94, and retracts the top column 93 into the mounting circular tube 91. Under the action of the second compression spring 398, one end of the clamping rod 394 is retracted into the rotating seat 393, so that the clamping rod 394 clamps the axial side of the magnetic core 37; In order to enable the side of the movable groove 399 to drive the push-back block 97 to move, a chamfered surface is provided on the top of one end of the push-back block 97, and the side wall of the movable groove 399 intersects with the chamfered surface in a vertical plane. Initially, when the rotating seat 393 is in a vertical state and the positioning block 95 is inserted into the interior of the mounting square tube 96, the distance between the side wall of the movable groove 399 and the end side of the push-back block 97 is not less than the distance from the end side of the positioning block 95 located inside the mounting square tube 96 to the side of the clamping rod 394, thereby enabling the positioning block 95 to be completely retracted into the movable hole 94.

[0043] like Figure 7-10 As shown, a power-taking device for outdoor poles provided by the present invention is provided. After the magnetic core 37 is installed, the power for fixing the magnetic core 37 comes from the second compression spring 398 and the first compression spring 396, and the second compression spring 398 and the first compression spring 396 are in a free active state, so that the magnetic core 37 is not locked. In order to relatively fix the magnetic core 37 and the clamping rod 394, a fastening mechanism 8 is further provided in this embodiment.
