Description

Technical Field

[0001] The utility model belongs to the technical field related to power transmission lines, and particularly relates to an electrical data collection device for power transmission lines. Background Art

[0002] The transmission line is realized by using a transformer to step up the voltage of the electric energy generated by the generator, and then connecting it to the transmission line through control equipment such as circuit breakers. In terms of structural form, the transmission line is divided into overhead transmission lines and cable lines. Overhead transmission lines are composed of line towers, conductors, insulators, line hardware, guy wires, tower foundations, grounding devices, etc., and are erected above the ground. According to the nature of the transmitted current, power transmission is divided into AC transmission and DC transmission.

[0003] When the transmission line is working normally, the power personnel will collect electrical parameters of the transmission line from time to time to prevent the occurrence of power accidents. When collecting electrical parameters, clamp-on current transformers are usually used to collect electrical parameters of the transmission line. Although the clamp-on current transformer can collect electrical parameters of the transmission line, when in use, the height is usually the maximum height of the user's arm. If the electrical parameters of the transmission line at a certain height are collected, the user needs to climb to a certain height to hold the clamp-on current transformer in contact with the transmission line. Because the height is fixed, it is not more convenient to use the line data collection work at a certain height, the work efficiency is low, and it is time-consuming and labor-intensive. Utility Model Content

[0004] In order to solve the problems mentioned in the above background technology, the purpose of the utility model is to provide an electrical data collection device for a power transmission line. The height of the entire device can be adjusted according to the height requirements of different power transmission lines to complete the data collection work. It has a simple structure, is easy to carry and has strong practicality.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A power transmission line electrical data collection device comprises a clamp-on current transformer body 1, a vertical rod 2 is detachably provided below the clamp-on current transformer body 1, a first cylinder 3 is sleeved on the outside of the vertical rod 2, and a gap is slidably provided between the vertical rod 2 and the first cylinder 3;

[0007] A vertical through slot 5 is formed on the side wall of the first cylinder 3 , and a stud 4 is slidably arranged through the through slot 5 , and one end of the stud 4 is threadedly connected to the side wall of the vertical rod 2 .

[0008] Through the above technical solution, the stud 4 can be lifted and slid on the inner wall of the through groove 5, thereby driving the vertical rod 2 to be lifted and moved in the first cylinder 3; by changing the total usable length of the first cylinder 3, the vertical rod 2 and the clamp-type current transformer body 1, the electrical parameter collection work of the transmission line at different heights can be carried out without the need for workers to climb, which is convenient, practical, simple and portable.

[0009] Furthermore, a sleeve 7 is provided on one side of the first cylinder 3 in contact with its outer wall, a second cylinder 8 is slidably embedded inside the sleeve 7, a push rod 9 is slidably inserted inside the second cylinder 8, and the top of the push rod 9 is in contact with the clamp-on current transformer body 1; a plurality of groups of evenly distributed through holes 10 are provided on the side wall of the push rod 9, a fixing hole is provided on one side of the second cylinder 8 corresponding to the through hole 10, and a bolt 11 is threadedly connected to the fixing hole and any one of the through holes 10.

[0010] Through the above technical solution, the fixing holes on the second cylinder 8 can be docked with the through holes 10 at different positions, and then fixed by bolt connection, so that the total length of the top rod 9 and the second cylinder 8 can be adjusted. As the placement height of the clamp-type current transformer body 1 changes (the height between the first cylinder 3 and the vertical rod 2 changes), the total length of the top rod 9 and the second cylinder 8 can also be adjusted so that the top rod 9 can stably contact the clamp-type current transformer body 1, so that when the clamp-type current transformer body 1 is used at different heights, the top rod 9 can stably push the clamp-type current transformer body 1 and unfold the clamp-type current transformer body 1 for contact with the power transmission line and use for electrical parameter collection.

[0011] Furthermore, a spring 13 is sleeved on the outer surface of the second cylinder 8 located below the sleeve 7 , the upper end of the spring 13 is fixedly connected to the sleeve 7 , and the lower end of the spring 13 is fixedly connected to the second cylinder 8 .

[0012] Through the above technical solution, the spring 13 can give the sleeve 7 a force to drive the push rod 9 and stably fit the push rod 9 to the clamp-on current transformer body 1.

[0013] Furthermore, the length of the sleeve 7 is shorter than the length of the first cylinder 3 , thus satisfying the coordination and structural properties of the entire device.

[0014] Furthermore, a handle 6 is fixedly connected to the outside of the stud 4 .

[0015] Through the above technical solution, the handle 6 can drive the stud 4 to rotate at the vertical rod 2, so that one end of the handle 6 is tightly fitted against the outer wall of the first cylinder 3. When the vertical rod and the first cylinder are tightly fitted, the handle 6 can limit the movement of the vertical rod 2, and then after adjusting the total length of the vertical rod 2 and the first cylinder 3, it can be fixed.

[0016] Furthermore, the clamp-on current transformer body 1 is threadably connected to the vertical rod 2 .

[0017] Through the above technical solution, the clamp-on current transformer body 1 can be disassembled from other structures by connecting the clamp-on current transformer body 1 with the thread of the vertical rod 2. Firstly, it is convenient to carry and assemble, and secondly, it can be used by hand when the electrical parameter collection of the transmission line at a certain height is not required.

[0018] Furthermore, a handle 12 is fixedly connected to the second cylinder 8, and the handle 12 can drive the second cylinder 8 to move up and down, thereby adjusting the height between the second cylinder and the push rod.

[0019] Compared with the prior art, the utility model of the power transmission line electrical data collection device has the following beneficial effects:

[0020] (1) The present invention can adjust the total use length of the first cylinder, the vertical rod, the stud, the through groove and the handle by moving the vertical rod upward in the first cylinder. The handle can also be used to drive the stud to rotate at the vertical rod. The handle and the vertical rod are pressed tightly together to limit the movement of the vertical rod, thereby changing the total use length of the first cylinder, the vertical rod and the clamp-on current transformer body. The electrical parameter collection work of the transmission line at different heights can be carried out according to the actual transmission line electrical parameter collection requirements. The electrical parameter collection work of the transmission line at a high place can be carried out without climbing, which saves time and effort and reduces the risk of work.

[0021] (2) Through the coordination among the push rod, through hole, bolt, sleeve and spring, when the total use length of the first cylinder, the vertical rod and the clamp-on current transformer body is changed, the fixing hole on the second cylinder can be connected with the through hole at different positions of the push rod by bolts, so that the total length of the push rod and the second cylinder can be changed, so that the push rod can be adjusted in height accordingly with the change of the placement height of the clamp-on current transformer body, thereby ensuring that when the cylinder drives the push rod to move close to the clamp-on current transformer body, the push rod can open the clamp-on current transformer body, and then the transmission line is placed in the clamp-on current transformer body to collect power parameters.

[0032] During specific implementation, the height can be adjusted according to specific needs to meet the data collection work of transmission lines at different heights.

[0034] In specific implementation, the fixing holes on the second cylinder 8 can be docked with the through holes 10 at different positions, and then fixed by bolt connection, so that the total length of the top rod 9 and the second cylinder 8 can be adjusted.
