Description

Technical Field

[0001] This invention relates to the field of circuit breaker technology, specifically to a multifunctional testing device and testing method for pole-mounted circuit breakers. Background Technology

[0002] A pole-mounted circuit breaker refers to a circuit breaker installed and operated on a utility pole. To monitor the operational status of a pole-mounted circuit breaker, the testing typically includes detecting load current, overload current, and short-circuit current for breaking and closing the power system, as well as bounce time. Existing testing devices are multi-functional testing instruments, which currently require at least two people. One of the testers needs to climb to the top of the pole using climbing equipment and then connect multiple data cables one by one to the testing channels of the pole-mounted circuit breaker. This results in low testing efficiency and safety. To address these issues, the inventor proposes a multi-functional testing device and method for pole-mounted circuit breakers. Summary of the Invention

[0003] To address the current problem that using multi-functional testing equipment requires at least two people, one of whom needs to climb to the top of the pole using climbing equipment, and then connect multiple data cables one by one to the testing channel of the pole-mounted circuit breaker, resulting in low testing efficiency and safety, the present invention aims to provide a multi-functional testing device and method for pole-mounted circuit breakers.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a multi-functional testing device for pole-mounted circuit breakers, comprising a pole, a vacuum circuit breaker body fixedly sleeved on the upper outer surface of the pole, a first clamping assembly and a second clamping assembly clamped and installed on the outer surface of the pole, a clamping power assembly installed between the first clamping assembly and the second clamping assembly, a guide frame fixedly connected to the second clamping assembly, a lifting assembly fixedly installed on the guide frame, the lifting assembly being pulsatorically connected to the first clamping assembly, and a testing device installed on the guide frame. The first clamping assembly and the second clamping assembly alternately clamp and fix the pole at the same time, and then the lifting assembly enables the tester and the testing device to move vertically up and down along the pole with the guide frame, thereby enabling the tester to quickly connect the testing device to the vacuum circuit breaker body for testing.

[0005] Preferably, the vacuum circuit breaker body is a ZW20-12 type outdoor AC high-voltage vacuum circuit breaker. A clamp is fixedly installed on the vacuum circuit breaker body, and the clamp is fixedly sleeved onto the outer surface of the pole. Multiple detection channels are provided on the vacuum circuit breaker body for connecting to a detection device via a data cable to detect multiple data points. The guide frame includes a base, on the upper surface of which a detection device and a lifting assembly are fixedly installed. A guardrail and a U-shaped frame are fixedly installed on the upper surface of the base. A cross groove is provided on the U-shaped frame, and an upper horizontal plate is slidably connected within the cross groove. A lower horizontal plate is fixedly connected to the bottom end of the U-shaped frame. The upper horizontal plate is fixedly connected to a first clamping assembly, and the lower horizontal plate is fixedly connected to a second clamping assembly. The inspector uses a safety rope connected to the guardrail, allowing the inspector to stand stably on the base and rise and fall with the base. The U-shaped frame can slide along the upper horizontal plate.

[0006] Preferably, the first clamping assembly includes a first arc-shaped block and a second arc-shaped block, which are sleeved on the outer surface of the pole. Multiple upper wear-resistant pads are fixedly provided on the inner walls of both the first and second arc-shaped blocks. Two upper guide rods are fixedly provided at both ends of the first arc-shaped block, and upper springs are sleeved on the outer surfaces of the upper guide rods. An upper U-shaped rod is fixedly connected to the first arc-shaped block, and an upper convex seat is fixedly connected to the outer surface of the second arc-shaped block. The upper convex seat is slidably connected to the upper guide rod and the upper U-shaped rod. The upper U-shaped rod is drive-connected to the clamping power assembly, and the upper guide rod is fixedly connected to the upper horizontal plate. When the second arc-shaped block slides along the upper convex seat via the upper U-shaped rod, it is guided by the upper guide rod, causing the first arc-shaped block to... The inner diameters of the first and second arc-shaped blocks change, thereby clamping and fixing the utility pole. The second clamping assembly includes a third and a fourth arc-shaped block, which are fitted onto the outer surface of the utility pole. Multiple lower wear-resistant pads are fixedly provided on the inner walls of both the third and fourth arc-shaped blocks. Two lower guide rods are fixedly provided at both ends of the third arc-shaped block, and a lower spring is fitted onto the outer surface of each lower guide rod. A lower U-shaped rod is fixedly connected to the third arc-shaped block, and a lower convex seat is fixedly connected to the outer surface of the fourth arc-shaped block. The lower convex seat is slidably connected to the lower guide rod and the lower U-shaped rod. The lower U-shaped rod is driven by the clamping power assembly, and the lower guide rod is fixedly connected to the lower horizontal plate. When the first and second arc-shaped blocks clamp... When holding the fixed pole, the fourth arc-shaped block slides along the lower convex seat via the lower U-shaped rod and is guided by the lower guide rod, so that the inner diameters of the third and fourth arc-shaped blocks are larger than the diameter of the pole, thus preventing the fixed pole from being clamped; the clamping power assembly includes a first motor, the first motor is fixedly connected to a first support block, the output end of the first motor is rotatably connected to a second support block, the first support block is fixedly connected to the lower convex seat, the second support block is fixedly connected to the upper convex seat, the output end of the first motor is fixedly provided with a first gear and a second gear, the first gear meshes with a first rack, the first rack is fixedly connected to the lower U-shaped rod, and the second gear meshes with a second rack, the second... The rack is fixedly connected to the upper U-shaped rod. The output end of the first motor drives the first gear and the second gear to rotate, so that the first rack and the second rack move in opposite directions, and then the second arc block and the fourth arc block move in opposite directions. The tooth directions of the first rack and the second rack are opposite. The first rack is located at the bottom end of the second rack. The first clamping assembly and the second clamping assembly can alternately clamp and fix the electric pole. The lifting assembly includes a second motor. The bottom end of the second motor is fixedly connected to a mounting base. The mounting base is fixedly located on the upper surface of the base. The output end of the second motor is fixedly provided with a lead screw. The lead screw is threadedly connected to the upper horizontal plate. The output end of the second motor causes the lead screw to rotate, thereby allowing the guide frame to rise along the electric pole.The testing device includes a testing box fixedly mounted on the upper surface of a base. A heat dissipation grid is provided on the testing box. A multi-functional testing instrument is fixedly installed inside the testing box. This instrument has powerful data analysis capabilities, enabling it to effectively analyze various parameters of the circuit breaker's mechanical characteristics and export data analysis curves, among other functions.

[0007] A testing method for a multifunctional testing device for pole-mounted circuit breakers includes the following steps:

[0008] Step 1: The ZW20-12 type outdoor AC high-voltage vacuum circuit breaker body is fixedly installed at the upper end of the pole with clamps. The vacuum circuit breaker body is equipped with a detection channel that can be connected to a multi-functional tester via a plug-in data cable to detect the working status of the vacuum circuit breaker body. The specific detection content is used for detecting the load current, overload current, and short-circuit current of the power system during breaking and closing, as well as the bounce time. The multi-functional tester has powerful data analysis functions, which can effectively analyze various indicators and parameters of the circuit breaker's mechanical characteristics and export data analysis curves, etc.

[0009] Step Two: Fix the testing box equipped with the multi-functional testing instrument onto the upper surface of the mounting base. The base is fixedly connected to the lower guide rod via the lower horizontal plate, allowing the multi-functional testing instrument to move vertically with the lower guide rod. The output end of the first motor drives the first and second gears to rotate, causing the first and second racks to move in opposite directions. This causes the second arc-shaped block to slide along the upper guide rod via the upper U-shaped rod, and cooperates with the first arc-shaped block to clamp and fix the electric rod with multiple annularly distributed upper wear-resistant pads. The fourth arc-shaped block moves in the opposite direction to the second arc-shaped block, causing the fourth arc-shaped block to cooperate with the third arc-shaped block. The inner diameter of the block is larger than the diameter of the pole. Then the second motor works, connecting the lead screw to the upper horizontal plate, and simultaneously moving the fourth arc block, the third arc block, and the base vertically upward along the pole. Then the first motor reverses, clamping and fixing the pole with the fourth and third arc blocks, increasing the diameter of the first and second arc blocks. The second motor is then started again, raising the first and second arc blocks a certain distance. The above actions are repeated, allowing the inspector and the multi-functional detector to stably climb to the vicinity of the vacuum circuit breaker body at the top of the pole for direct and rapid testing.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] 1. By setting up two clamping devices that alternately clamp and fix the pole, and then driving the lead screw through the output end of the second motor to rotate, the inspector on the guide frame and the multi-energy detector can be stably raised vertically along the pole to the vacuum circuit breaker body. This allows for convenient direct detection of multiple operating data of the vacuum circuit breaker body using a data cable, thereby improving detection efficiency. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figure 1-5As shown, the present invention provides a multifunctional testing device for pole-mounted circuit breakers, including a pole 1. A vacuum circuit breaker body 2 is fixedly sleeved on the upper outer surface of the pole 1.

[0021] By adopting the above technical solution, the first clamping component 3 and the second clamping component 4 alternately clamp and fix the pole 1 at the same time. Then, the lifting component 6 enables the inspector and the inspection device 8 to move vertically up and down along the pole 1 together with the guide frame 7, thereby enabling the inspector to quickly connect the inspection device 8 to the vacuum circuit breaker body 2 for inspection.

[0023] By adopting the above technical solution, multiple detection channels 22 provided on the vacuum circuit breaker body 2 are used to connect with the detection device 8 using data cables to detect multiple data.

[0024] The guide frame 7 includes a base 71, on the upper surface of which a detection device 8 and a lifting assembly 6 are fixedly installed. A guardrail 72 and a U-shaped frame 73 are fixedly provided on the upper surface of the base 71. A cross groove 731 is provided on the U-shaped frame 73. An upper horizontal plate 74 is slidably connected in the cross groove 731. A lower horizontal plate 75 is fixedly connected to the bottom end of the U-shaped frame 73. The upper horizontal plate 74 is fixedly connected to the first clamping assembly 3, and the lower horizontal plate 75 is fixedly connected to the second clamping assembly 4.

[0025] By adopting the above technical solution, the tester uses a safety rope to connect with the guardrail 72, so that the tester can stand stably on the base 71 and rise and fall together with the base 71. The U-shaped frame 73 can slide along the upper horizontal plate 74.

[0026] The first clamping assembly 3 includes a first arc-shaped block 31 and a second arc-shaped block 32. The first arc-shaped block 31 and the second arc-shaped block 32 are sleeved on the outer surface of the pole 1. Multiple upper wear-resistant pads 33 are fixedly provided on the inner walls of the first arc-shaped block 31 and the second arc-shaped block 32. Two upper guide rods 35 are fixedly provided at both ends of the first arc-shaped block 31. An upper spring 36 is sleeved on the outer surface of the upper guide rod 35.

The upper guide rod 35 is fixedly connected to the upper horizontal plate 74.

[0027] By adopting the above technical solution, when the second arc-shaped block 32 slides along the upper convex seat 37 via the upper U-shaped rod 34, it is guided by the upper guide rod 35, so that the inner diameter of the first arc-shaped block 31 and the second arc-shaped block 32 changes, thereby clamping and fixing the electric pole 1.

[0028] The second clamping assembly 4 includes a third arc-shaped block 41 and a fourth arc-shaped block 42. The third arc-shaped block 41 and the fourth arc-shaped block 42 are sleeved on the outer surface of the pole 1. Multiple lower wear-resistant pads 43 are fixedly provided on the inner walls of the third arc-shaped block 41 and the fourth arc-shaped block 42. Two lower guide rods 45 are fixedly provided at both ends of the third arc-shaped block 41. A lower spring 46 is sleeved on the outer surface of the lower guide rod 45.

The lower guide rod 45 is fixedly connected to the lower horizontal plate 75.

[0029] By adopting the above technical solution, when the first arc-shaped block 31 and the second arc-shaped block 32 clamp and fix the electric pole 1, the fourth arc-shaped block 42 slides along the lower convex seat 47 through the lower U-shaped rod 44 and is guided by the lower guide rod 45, so that the inner diameter of the third arc-shaped block 41 and the fourth arc-shaped block 42 is greater than the diameter of the electric pole 1, and thus will not clamp and fix the electric pole 1.

[0030] The clamping power assembly 5 includes a first motor 51, a first support block 52 fixedly connected to the first motor 51, a second support block 57 rotatably connected to the output end of the first motor 51, the first support block 52 fixedly connected to the lower convex seat 47, the second support block 57 fixedly connected to the upper convex seat 37, a first gear 53 and a second gear 55 fixedly provided at the output end of the first motor 51, the first gear 53 meshing with a first rack 54, the first rack 54 fixedly connected to the lower U-shaped rod 44, the second gear 55 meshing with a second rack 56, and the second rack 56 fixedly connected to the upper U-shaped rod 34.

[0031] By adopting the above technical solution, the output end of the first motor 51 drives the first gear 53 and the second gear 55 to rotate, so that the first rack 54 and the second rack 56 move in opposite directions, and then make the second arc block 32 and the fourth arc block 42 move in opposite directions.

The mounting base 62 is fixedly disposed on the upper surface of the base 71. The output end of the second motor 61 is fixedly provided with a lead screw 63, which is threadedly connected to the upper horizontal plate 74.

[0035] By adopting the above technical solution, the output end of the second motor 61 causes the lead screw 63 to rotate, thereby enabling the guide frame 7 to rise along the electric pole 1.

[0036] The detection device 8 includes a detection box 81, which is fixedly mounted on the upper surface of the base 71. A heat dissipation grid 82 is provided on the detection box 81, and a multi-functional detector 83 is fixedly installed inside the detection box 81.

[0037] By adopting the above technical solution, the multi-functional tester 83 has powerful data analysis capabilities, which can effectively analyze various index parameters of the mechanical characteristics of circuit breakers and export data analysis curves and other functions.

[0038] A testing method for a multifunctional testing device for pole-mounted circuit breakers includes the following steps:

[0039] Step 1: The ZW20-12 type outdoor AC high-voltage vacuum circuit breaker body 2 is fixedly installed on the upper end of the pole 1 by clamp 21. The vacuum circuit breaker body 2 is equipped with a detection channel 22, which can be connected to the multi-functional tester 83 by plugging in a data cable to realize the detection of the working status of the vacuum circuit breaker body 2. The specific detection content is used for breaking and closing the load current, overload current and short circuit current of the power system, bounce time, etc. The multi-functional tester 83 has powerful data analysis function, which can effectively analyze various index parameters of the mechanical characteristics of the circuit breaker and export data analysis curves, etc.

[0040] Step 2: Fix the testing box 81, which houses the multifunctional testing instrument 83, onto the upper surface of the mounting base 71. The base 71 is fixedly connected to the lower guide rod 45 via the lower horizontal plate 75, allowing the multifunctional testing instrument 83 to move vertically with the lower guide rod 45. The output end of the first motor 51 drives the first gear 53 and the second gear 55 to rotate, causing the first rack 54 and the second rack 56 to move in opposite directions. This causes the second arc-shaped block 32 to slide along the upper guide rod 35 via the upper U-shaped rod 34, and cooperate with the first arc-shaped block 31 to clamp and fix the electric rod 1 with multiple annularly distributed upper wear-resistant pads 33. The fourth arc-shaped block 42 moves in the opposite direction to the second arc-shaped block 32, causing the fourth arc-shaped block 42 to cooperate with the first arc-shaped block 31 to move in opposite directions. The inner diameter of the three arc-shaped blocks 41 is larger than the diameter of the pole 1. Then the second motor 61 works, so that the lead screw 63 is threadedly connected to the upper horizontal plate 74, and the fourth arc-shaped block 42, the third arc-shaped block 41 and the base 71 move vertically upward along the pole 1. Then the first motor 51 reverses, so that the fourth arc-shaped block 42 and the third arc-shaped block 41 clamp and fix the pole 1. The diameters of the first arc-shaped block 31 and the second arc-shaped block 32 become larger. Then the second motor 61 is started again, so that the first arc-shaped block 31 and the second arc-shaped block 32 rise a certain distance. The above actions are repeated, so that the inspector and the multi-functional detector 83 can stably climb to the vicinity of the vacuum circuit breaker body 2 at the upper end of the pole 1 for direct and rapid testing.

[0041] Working Principle: The ZW20-12 type outdoor AC high-voltage vacuum circuit breaker body 2 is fixedly installed on the upper end of the pole 1 by clamp 21. The vacuum circuit breaker body 2 is equipped with a detection channel 22, which can be connected to a multi-functional tester 83 via a plug-in data cable to detect the working status of the vacuum circuit breaker body 2. The specific detection content is used for breaking and closing the load current, overload current, and short-circuit current of the power system, as well as the bounce time. The multi-functional tester 83 has powerful data analysis functions, which can effectively analyze various indicators and parameters of the circuit breaker's mechanical characteristics and export data analysis curves. The detection box 81, on which the multi-functional tester 83 is installed, is fixedly installed on the upper surface of the base 71. The base 71 is fixedly connected to the lower guide rod 45 through the lower horizontal plate 75, so that the multi-functional tester 83 can move vertically with the lower guide rod 45. The output end of the first motor 51 drives the first gear 53 and the second gear 55 to rotate, so that the first rack 54 and the second rack 56 move in the direction of rotation. Conversely, the second arc-shaped block 32 slides along the upper guide rod 35 via the upper U-shaped rod 34, and cooperates with the first arc-shaped block 31 to clamp and fix the electric rod 1 with multiple annularly distributed upper wear-resistant pads 33. The fourth arc-shaped block 42 moves in the opposite direction to the second arc-shaped block 32, so that the inner diameter of the fourth arc-shaped block 42 and the third arc-shaped block 41 is larger than the diameter of the electric rod 1. Then the second motor 61 works, so that the lead screw 63 is threadedly connected to the upper horizontal plate 74, and at the same time, the fourth arc-shaped block 42 and the third arc-shaped block 32 can move in opposite directions. The entire assembly of 41 and base 71 moves vertically upward along pole 1. Then, the first motor 51 reverses direction, causing the fourth arc block 42 and the third arc block 41 to clamp and fix pole 1. The diameters of the first arc block 31 and the second arc block 32 increase. Then, the second motor 61 is started, causing the first arc block 31 and the second arc block 32 to rise a certain distance. The above actions are repeated, allowing the inspector and the multi-functional detector 83 to stably climb to the vicinity of the vacuum circuit breaker body 2 at the upper end of pole 1 for direct and rapid testing.
