Description
Technical Field
[0001] This utility model relates to the field of high-voltage line fault detection technology, and in particular to a high-voltage line fault detection device. Background Technology
[0002] High-voltage line fault detection refers to the entire process of using a series of technical means and equipment to monitor, analyze, judge and locate high-voltage transmission and distribution lines (usually referring to voltage levels of 35kV and above) in order to discover abnormal operating conditions of the lines, potential insulation deterioration hazards and determine the location of the fault.
[0003] When performing short-circuit detection on high-voltage lines, a line fault indicator is required. It is installed directly on the high-voltage line to detect and determine whether there is an abnormal current in the line. It is mainly used for short-circuit faults and single-wire grounding faults.
[0004] Traditional line fault indicators are typically installed directly on the line using clip-on or snap-on methods, but their installation and removal methods need improvement. To facilitate installation and removal, a high-voltage line fault detection device is proposed, making it easier for operators to use. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-voltage line fault detection device, which effectively solves the deficiencies of the prior art.
[0006] To achieve the above objectives, one embodiment of the present invention provides a high-voltage line fault detection device, including a hollow mounting base, a card seat installed at the top of the hollow mounting base, a card groove formed by the downward indentation of the middle of the top of the card seat, and a first mounting base and a second mounting base respectively installed on both sides of the top of the card seat. An arc-shaped clamping plate and a torsion spring are rotatably mounted on the top of the first mounting base via pins. The torsion spring drives the arc-shaped clamping plate to rotate. Wire supports are installed inside the arc-shaped clamping plate and inside the slot. A first pull ring is installed on the side of the arc-shaped clamping plate near the outer wall of the torsion spring. The top surface of the second mounting base is equipped with a guide rail, and a clamping block is slidably installed inside it. The side of the clamping block is recessed inward and engages with the end of the arc-shaped pressing plate away from the torsion spring. A spring is installed between the other side of the clamping block and the inner wall of the guide rail. A second pull ring is slidably connected to the side of the guide rail near the spring. The end of the second pull ring passes through the spring and is threadedly connected to one side of the clamping block.
[0007] Preferably, the hollow mounting base has multiple hollow sections at its bottom end, and the bottom end of the hollow mounting base is hemispherical. A transparent cover is installed at the bottom end of the hollow mounting base, and a protrusion is installed at the bottom end of the outer wall of the transparent cover for threaded connection with the external insulating rod. This design facilitates the stable installation of the transparent cover on the outer wall of the hollow mounting base. Since the transparent cover is made of transparent material, it facilitates the transmission of light, allowing inspection personnel to observe the operation of the high-voltage line fault detection equipment. At the same time, the top of the transparent cover is fixedly connected to the hollow mounting base by adhesive, which facilitates installation.
[0008] Preferably, both ends of the first and second mounting bases are rotatably mounted with bolts, and the four bolts pass through the card holder and are threadedly connected to the hollow mounting base. This method facilitates the fixed connection between the card holder and the hollow mounting base, making it convenient for operators to perform initial installation and subsequent disassembly. At the same time, the hollow mounting base, card holder, first mounting base and second mounting base are processed separately in the above manner, reducing the size of the parts and facilitating the assembly of the parts.
[0009] Preferably, in any of the above solutions, the inner wall of the arc-shaped clamping plate and the inner wall of the slot are provided with two limiting holes, and the outer circular surfaces of the two wire supports are each equipped with a limiting post that matches the limiting hole. By using this solution, it is easy to install the limiting post inside the limiting hole, and the two are connected by interference fit, so that the two wire supports are respectively installed inside the slot and the arc-shaped clamping plate. After the arc-shaped clamping plate is engaged with the clamping block, the two wire supports press the high-voltage line, so that the high-voltage line fault detection equipment is stably installed.
[0010] Preferably, in any of the above solutions, the arc-shaped clamping plate has rounded corners at the end away from the torsion spring and at one corner of the top of the clamping block. The width of the arc-shaped clamping plate is the same as the length of the clamping block. By using this solution, it is convenient for the rounded corners at the top of the clamping block and the end of the arc-shaped clamping plate to contact each other in the early stage of the clamping of the arc-shaped clamping plate and the clamping block, so that the arc-shaped clamping plate pushes the clamping block, and the clamping block pushes the spring, and the spring is compressed again. Under the action of the torsional force of the torsion spring and the pushing force of the external insulating rod, the arc-shaped clamping plate and the clamping block are stably clamped together, ensuring the stability of the connection between the two.
[0011] This utility model has the following advantages: 1. This high-voltage line fault detection device comprises a hollow mounting base, a clamping base, a first mounting base, and a second mounting base. A clamping block is slidably mounted on the top of the second mounting base and pushed by a spring. A torsion spring and an arc-shaped pressure plate are rotatably mounted on the top of the first mounting base. The torsion spring twists the arc-shaped pressure plate to rotate. In use, one insulating rod is threadedly connected to the protrusion, and the top of another insulating rod is clamped inside the first pull ring. When the wire enters the lower wire support, the other insulating rod pushes upward to rotate the arc-shaped pressure plate, causing one end of the arc-shaped pressure plate to engage with the middle of the clamping block. The installation of the high-voltage line fault detection equipment is completed by snapping it in place. For disassembly, one insulating rod is threaded onto the protrusion, and the top of another insulating rod is snapped into the second pull ring. Pulling outwards separates the clamping block from the arc-shaped pressure plate, allowing the insulating rod to be pulled downwards. This causes the arc-shaped pressure plate on the power line to rotate at a certain angle, sliding the top of the insulating rod out of the second pull ring and inserting it into the first clamping ring. Pulling it down increases the angle of the arc-shaped pressure plate, allowing the entire assembly to be removed quickly. The overall structure is simple, facilitating installation and disassembly by operators.
[0012] 2. This high-voltage line fault detection device comprises a second mounting base, a guide rail, a clamping block, a spring, and a second pull ring. The second pull ring passes through the guide rail and the spring and is threadedly connected to one side of the clamping block. The guide rail facilitates the limiting of the clamping block. After the high-voltage line fault detection device is installed on the high-voltage line, the torsion spring and the spring utilize their accumulated potential energy to stably clamp the clamping block with the arc-shaped pressing plate, preventing accidental disengagement and ensuring that the high-voltage line fault detection device is stably installed on the line.

Detailed Implementation
[0015] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.
[0016] like Figures 1 to 8 As shown, a high-voltage line fault detection device includes a hollow mounting base 1, a card holder 14 is installed on the top of the hollow mounting base 1, the middle of the top of the card holder 14 is recessed downward to form a card groove 3, and a first mounting base 13 and a second mounting base 4 are respectively installed on both sides of the top of the card holder 14. The top of the first mounting base 13 is rotatably mounted with an arc-shaped clamping plate 10 and a torsion spring 12 via pins. The torsion spring 12 drives the arc-shaped clamping plate 10 to rotate. The inside of the arc-shaped clamping plate 10 and the inside of the slot 3 are both equipped with wire supports 9. The side of the arc-shaped clamping plate 10 near the outer wall of the torsion spring 12 is equipped with a first pull ring 11. The top surface of the second mounting base 4 is equipped with a guide rail 5, and a clamping block 8 is slidably installed inside it. The side of the clamping block 8 is recessed inward and engages with the end of the arc-shaped pressing plate 10 away from the torsion spring 12. A spring 7 (in a compressed state) is installed between the other side of the clamping block 8 and the inner wall of the guide rail 5. A second pull ring 6 is slidably connected to the side of the guide rail 5 near the spring 7. The end of the second pull ring 6 passes through the spring 7 and is threadedly connected to one side of the clamping block 8.
[0017] The hollow mounting base 1 has a hollow structure and a circuit board installed inside. The circuit board has a self-powered circuit for obtaining power through electromagnetic induction. At the same time, a magnetic core is installed inside the arc-shaped clamping plate 10. A current transformer (CT) is installed on the circuit board, which forms a closed circuit with the conductor core. The current is then collected by electromagnetic induction. A display component is installed at the bottom of the hollow mounting base 1 near the hollow part, and a flip-up window and an LED flash are installed on it.
[0018] The bottom of the hollow mounting base 1 has multiple hollow sections. The bottom of the hollow mounting base 1 is hemispherical. A transparent cover 2 is installed at the bottom of the hollow mounting base 1. The bottom of the outer wall of the transparent cover 2 has a protrusion 17 that is threadedly connected to the external insulating rod. As an optional technical solution of this utility model, this makes it easier for the transparent cover 2 to be stably installed on the outer wall of the hollow mounting base 1. Since the transparent cover 2 is made of transparent material, it facilitates the transmission of light, making it easier for inspection personnel to observe the operation of the high-voltage line fault detection equipment. At the same time, the top of the transparent cover 2 is fixedly connected to the hollow mounting base 1 by adhesive, which facilitates installation.
[0019] Bolts are rotatably installed at both ends of the first mounting base 13 and the second mounting base 4. Four bolts pass through the card holder 14 and are threadedly connected to the hollow mounting base 1. As an optional technical solution of this utility model, this facilitates the fixed connection between the card holder 14 and the hollow mounting base 1, making it convenient for operators to perform initial installation and subsequent disassembly. At the same time, the above method allows for the separate processing of the hollow mounting base 1, card holder 14, first mounting base 13 and second mounting base 4, reducing the size of the parts and facilitating the assembly of the parts.
[0020] Both the inner wall of the arc-shaped clamping plate 10 and the inner wall of the slot 3 have two limiting holes 15. The outer circular surfaces of the two line supports 9 are each equipped with limiting posts 16 that are compatible with the limiting holes 15. As an optional technical solution of this utility model, this makes it easy to install the limiting posts 16 inside the limiting holes 15. The two are connected by interference fit, so that the two line supports 9 are installed inside the slot 3 and the arc-shaped clamping plate 10 respectively. After the arc-shaped clamping plate 10 is engaged with the clamping block 8, the two line supports 9 clamp the high-voltage line, so that the high-voltage line fault detection equipment is installed stably.
[0021] The arc-shaped clamping plate 10 has rounded corners at the end away from the torsion spring 12 and at one corner of the top of the clamping block 8. The width of the arc-shaped clamping plate 10 is the same as the length of the clamping block 8. As an optional technical solution of this utility model, this facilitates the contact between the rounded corners of the top of the clamping block 8 and the end of the arc-shaped clamping plate 10 in the early stage of the clamping of the arc-shaped clamping plate 10 and the clamping block 8, so that the arc-shaped clamping plate 10 pushes the clamping block 8, and the clamping block 8 pushes the spring 12, and the spring 12 is compressed again. Under the action of the torsional force of the torsion spring 12 and the pushing force of the external insulating rod, the arc-shaped clamping plate 10 and the clamping block 8 are stably clamped, ensuring the stability of the connection between the two.
[0022] This high-voltage line fault detection equipment requires the following steps to be used: 1) During installation, two insulating rods are required. One insulating rod is threaded to the protrusion 17, and the top of the other insulating rod is inserted into the first retaining ring 11 and pushes the arc-shaped clamping plate 10 into the open state. 2) The high-voltage line fault detection equipment is lifted synchronously by two insulating rods. After the wire enters the interior of the lower line support 9, the other insulating rod is pushed upward to rotate the arc-shaped clamping plate 10. With the torsional force of the torsion spring 12, one end of the arc-shaped clamping plate 10 is engaged with the clamping block 8, thus completing the installation of the high-voltage line fault detection equipment. 3) During disassembly, two insulating rods are required. One insulating rod is threaded to the protrusion 17, and the top of the other insulating rod is engaged with the second pull ring 6. This insulating rod contacts the transparent shell to form a lever structure. Dragging the second pull ring 6 causes the clamping block 8 to separate from the arc-shaped pressing plate 10. 4) Control the two insulating rods to move downwards, so that the arc-shaped pressing plate 10 opens at a certain angle. The top of the insulating rod slides out from the second pull ring 6 and inserts into the inside of the first retaining ring 11 and pulls it down, increasing the angle of the arc-shaped pressing plate 10, thus completing the removal of the whole.
[0023] In summary, during use, the user sets up a hollow mounting base 1, a clamping base 14, a first mounting base 13, and a second mounting base 4. A clamping block 8 is slidably mounted on the top of the second mounting base 4 and pushed by a spring 7. A torsion spring 12 and an arc-shaped pressure plate 10 are rotatably mounted on the top of the first mounting base 13. The torsion spring 12 twists the arc-shaped pressure plate 10 to rotate. During use, one insulating rod is threaded to the protrusion 17, and the top of another insulating rod is clamped inside the first pull ring 11. When the wire enters the lower wire support 9, the other insulating rod is pushed upwards to rotate the arc-shaped pressure plate 10, causing one end of the arc-shaped pressure plate 10 to engage with the middle of the clamping block 8, thus completing the installation of the high-voltage line fault detection device. During disassembly, one insulating rod is threaded to the protrusion 17, and the top of another insulating rod is clamped to the second pull ring 6, pulling outwards to clamp the block. 8 separates from the arc-shaped clamping plate 10, thereby controlling the insulating rod to pull the whole unit downward. The arc-shaped clamping plate 10 on the wire pushes to rotate at a certain angle, causing the top of the insulating rod to slide out from the second pull ring 6 and insert into the inside of the first retaining ring 11 and pull down, increasing the angle of the arc-shaped clamping plate 10, completing the removal of the whole unit, realizing quick disassembly. The overall structure is simple and convenient for operators to install and disassemble. Then, by setting the second mounting base 4, guide rail 5, clamping block 8, spring 7 and second pull ring 6, the second pull ring 6 passes through the guide rail 5 and spring 7 and is threaded to one side of the clamping block 8. The guide rail 5 facilitates the limiting of the clamping block 8. After the high-voltage line fault detection equipment is installed on the high-voltage line, the torsion spring 12 and spring 7 use their accumulated potential energy to make the clamping block 8 stably clamped with the arc-shaped clamping plate 10, preventing accidental disengagement and ensuring that the high-voltage line fault detection equipment is stably installed on the line.
