Description

Technical Field

[0001] This utility model relates to the field of power technology, and in particular to a distribution network fault early warning and location device that is easy to install and disassemble. Background Technology

[0002] With the rapid pace of economic development, the demand for electricity from various industries has increased significantly, placing higher demands on the safe and reliable operation of power distribution networks. Overhead power distribution lines are a crucial component of the power system and a vital basis for transmitting electrical energy.

[0003] The existing Chinese patent number is CN220419471U. This utility model relates to a fault early warning and precise positioning device for overhead power distribution lines based on traveling waves. It includes an upper shell, a lower shell, a CT (current transformer) coil, a main board, a current sensor, a GPS device, a 4G device, and a fixing device. The upper and lower shells have hollow internal structures. Grooves are provided axially on the bottom and top planes of both the upper and lower shells. The bottom of the upper shell connects to the top of the lower shell, and the grooves form channels. The CT coil is arched and is installed in the grooves at the bottom and top of the upper and lower shell cavities, respectively. The arched feet of the CT coil are located on both sides of the grooves. This utility model has fewer internal components, miniaturized parts, a smaller footprint, lighter weight, and more concentrated functions. It adopts traveling wave dual-end positioning, enabling rapid response after a fault occurs, achieving real-time alarm and precise positioning, reducing fault escalation and power outage time, and has a wide range of applications, making it less susceptible to external factors.

[0004] Although the above solutions have advantages such as rapid response after a fault occurs, real-time alarm and accurate location, reduced fault escalation and power outage time, and wide applicability, they are very inconvenient for workers to install. Workers need to pick up the upper and lower casings by hand and snap them onto the line. Once the upper and lower casings are correctly installed on the power line, workers need to use matching fixing clips or other fixing devices to fix the power distribution network fault warning and location device on the power line, which is too time-consuming and labor-intensive.

[0018] The technical effect of adopting the above-mentioned further solution is that when the upper and lower chassis are closed, the clamping plate will move due to pressure.

[0019] In a preferred embodiment, each of the four sets of second sliders has a telescopic column fixedly installed at its bottom, the inner surfaces of the four sets of return springs are movably sleeved on the outer surfaces of the telescopic columns, and the other ends of the four sets of return springs and the four sets of telescopic columns are fixedly installed inside the fixed structure.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1, please refer to Figure 1-4 This utility model provides a technical solution: a power distribution network fault early warning and location device that is easy to disassemble and assemble, including an upper chassis 1 and a lower chassis 101. A first slider 102 is fixedly installed at the front center of both the upper chassis 1 and the lower chassis 101. A protective box 103 is movably fitted onto the front outer surface of the two first sliders 102. A first rotating rod 104 is movably embedded at the bottom center of the protective box 103. A crank 105 is fixedly installed at the bottom of the first rotating rod 104. A first groove 109 is formed at the rear center of the protective box 103. The two first sliders 102... The outer surfaces of the two slides are slidably connected to the inner surface of the first slide groove 109. A forward rotation screw 106 is fixedly installed on the top of the first rotating rod 104. One of the two first sliders 102 is movably sleeved on the outer surface of the forward rotation screw 106. A second rotating rod 107 is fixedly installed on the top of the forward rotation screw 106. A reverse rotation screw 108 is fixedly installed on the top of the second rotating rod 107. The top outer surface of the reverse rotation screw 108 is movably embedded in the top side of the inner wall of the protective box 103. The other of the two first sliders 102 is movably sleeved on the outer surface of the reverse rotation screw 108.

[0032] In this embodiment, the upper housing 1 and lower housing 101 are first fitted onto the wiring. The crank 105 on the rotating protective box 103 is driven by the first rotating rod 104 to the forward rotating screw 106, which in turn drives the second rotating rod 107 to rotate. Simultaneously, the rotating rod 107 drives the reverse rotating screw 108, causing the forward and reverse rotating screws 106 to rotate synchronously. When the forward and reverse rotating screws 106 and 108 rotate, they drive the first slider 102 to perform a relative translational movement through the first sliding groove 109. The first slider 102 then drives the upper housing 1 and lower housing 101 to perform synchronous relative movement, engaging them onto the wiring. When the upper housing 1 and lower housing 101 are closed, pressure... The clamping plate 207 is moved, and when the clamping plate 207 moves, it will cause the second slider 206 to slide outward on the inner surface of the second slide groove 205 on the fixed structure 204, thereby causing the clamping plate 207 to move outward synchronously. At the same time, it will cause the return spring 209 and the telescopic column 208 to retract, fixing both sides of the line. Through the forward rotation screw 106 and the reverse rotation screw 108, the operator only needs to turn the handle 105 to fix the device to the line when using it, which greatly improves the operating efficiency. At the same time, the setting of the fixed structure 204 can increase the reliability of the device, ensuring that the upper housing 1 and the lower housing 101 remain stable when they are engaged with the power line, and are not easy to loosen or fall off.

[0033] Example 2, as Figure 1-4 As shown, a first rubber pad 2 is fixedly installed at the bottom center of the upper chassis 1, and first sealing rings 202 are fixedly installed on both sides of the bottom of the upper chassis 1. A second rubber pad 201 is fixedly installed at the top center of the lower chassis 101, and second sealing rings 203 are fixedly installed on both sides of the top of the lower chassis 101. Fixing structures 204 are fixedly installed on both sides of the upper chassis 1 and the lower chassis 101. Second sliding grooves 205 are opened on both sides of the inner wall of the four fixing structures 204, and the inner surfaces of the eight second sliding grooves 205 can slide. The system is connected to a second slider 206. The eight second sliders 206 are divided into four groups. Each of the four groups of second sliders 206 has a clamp 207 fixedly installed on one side opposite to the other. Each of the four groups of second sliders 206 has a return spring 209 fixedly installed at the bottom. Each of the four groups of second sliders 206 has a telescopic column 208 fixedly installed at the bottom. The inner surfaces of the four groups of return springs 209 are movably sleeved on the outer surfaces of the telescopic columns 208. The other ends of the four groups of return springs 209 and the four groups of telescopic columns 208 are fixedly installed inside the fixed structure 204.

[0034] In this embodiment, when the upper chassis 1 and the lower chassis 101 move relative to each other, the upper chassis 1 drives the first rubber pad 2 to move downward, so that it fits against the top outer surface of the circuit. Then, the lower chassis 101 drives the second rubber pad 201 to move upward, so that it fits against the bottom outer surface of the circuit. At the same time, the first sealing ring 202 and the second sealing ring 203 are closed. Through the setting of the first rubber pad 2 and other structures, the sealing performance between the upper chassis 1 and the lower chassis 101 and the circuit is improved when they are closed, effectively preventing external impurities such as moisture and dust from entering the interior and affecting its use.

[0035] Working Principle: In use, the upper housing 1 and lower housing 101 are first fitted onto the wiring. The crank 105 on the rotating protective box 103 transmits power to the forward lead screw 106 via the first rotating rod 104, which in turn drives the second rotating rod 107 to rotate. Simultaneously, the second rotating rod 107 transmits power to the reverse lead screw 108, causing the forward and reverse lead screws 106 and 108 to rotate synchronously. When the forward and reverse lead screws 106 and 108 rotate, they drive the first slider 102 to move relative to each other through the first sliding groove 109. The first slider 102 then drives the upper housing 1 and lower housing 101 to move synchronously relative to each other, engaging them onto the wiring. When the upper housing 1 and lower housing 101 are closed, they will... The pressure drives the clamping plate 207 to move, and when the clamping plate 207 moves, it drives the second slider 206 to slide outward on the inner surface of the second slide groove 205 on the fixed structure 204, thereby causing the clamping plate 207 to move outward synchronously. At the same time, it drives the return spring 209 and the telescopic column 208 to retract, fixing both sides of the line. Through the forward rotation screw 106 and the reverse rotation screw 108, the operator only needs to turn the handle 105 to fix the device to the line when in use, which greatly improves the operating efficiency. At the same time, the setting of the fixed structure 204 can increase the reliability of the device, ensuring that the upper housing 1 and the lower housing 101 remain stable when locked onto the power line, and are not easy to loosen or fall off. During use, when the upper chassis 1 and the lower chassis 101 move relative to each other, the upper chassis 1 drives the first rubber pad 2 to move downwards, so that it fits against the top outer surface of the circuit. Then, the lower chassis 101 drives the second rubber pad 201 to move upwards, so that it fits against the bottom outer surface of the circuit. At the same time, the first sealing ring 202 and the second sealing ring 203 are closed. Through the design of the first rubber pad 2 and other structures, the sealing performance between the upper chassis 1 and the lower chassis 101 and the circuit is improved when they are closed, effectively preventing external impurities such as moisture and dust from entering the interior and affecting its use.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
