Description

Technical Field

[0001] The present invention relates to the technical field of transmission project design, and particularly to a sub-span calculation method for the combined layout of conductor spacers and double pendulum anti-vibration devices in a sub-span. Background Art

[0002] A conductor spacer is a protective fitting installed on a multi-split conductor, which can play a role in preventing conductor vibration and avoiding mutual whipping of conductors; a double pendulum anti-vibration device is an anti-vibration device that can effectively suppress conductor vibration. In general areas, double pendulum anti-vibration devices are not installed, but for overhead transmission lines passing through areas prone to conductor vibration, both are often required to be installed. In actual projects, there are different technical requirements for the installation positions of conductor spacers and double pendulum anti-vibration devices. In existing methods, designers of transmission projects often separately give the installation positions of conductor spacers and double pendulum anti-vibration devices, and construction workers install them with reference.

[0003] This method of separately arranging positions often results in a situation where conductor spacers also need to be installed at the positions where double pendulum anti-vibration devices are theoretically installed. In practical applications, in this case, the installation of conductor spacers will be cancelled and the installation of double pendulum anti-vibration devices will be retained, but it will cause problems such as inaccurate statistics of the number of conductor spacers in the early stage, unreasonable purchase quantity, and unreasonable distance between conductor spacers and double pendulum anti-vibration devices.

Figure 3 It is a schematic diagram of the double-pendulum anti-vibration device, and the conductor spacer damper does not include the following two double-pendulums.

[0021] I. Calculate the installation sub-span sequence of the conductor spacer damper on the line length In a specific implementation manner of the embodiment of the present invention, calculate the installation sub-span sequence of the conductor spacer damper on the line length based on the line length and the average sub-span of the conductor spacer damper, including: Let the line length be L, the average sub-span of the conductor spacer damper be S, the installation quantity of the conductor spacer damper be N, the first sub-span value be S1, the second sub-span value be S2, the third sub-span value be S3,..., and the (N + 1)-th sub-span value be SN+1: N = L / S, where N is rounded up; in a specific implementation manner of the embodiment of the present invention, then: When N = 1, S1 = 0.6S, S2 = 0.4S; When N = 2, S1 = 0.6S, S2 = S, S3 = 0.4S; When N = 3, S1 = 0.65S, S2 = 1.05S, S3 = 0.8S, S4 = 0.5S; When N = 4, S1 = 0.6S, S2 = S, S3 = 0.85S, S4 = S, S5 = 0.55S; When N = 5, S1 = 0.6S, S2 = S, S3 = 0.8S, S4 = 1.05S, S5 = S, S6 = 0.55S; When N > 5 and is an even number, S1 = 0.6S, S2 = S, S3 = 0.9S, S4 = 1.1S, ……, SN-3 = 0.9S, SN-2 = 1.1S, SN-1 = 0.85S, SN = S, SN+1 = 0.55S; When N > 5 and is an odd number, S1 = 0.6S, S2 = S, S3 = 0.9S, S4 = 1.1S, ……, S N-4 = 0.9S, SN-3 = 1.1S, SN-2 = S, SN-1 = 0.85S, SN = S, SN+1 = 0.55S.

[0022] In this embodiment, N = 600 / 60 = 10. Since N is an even number greater than 5, the installation sub-span sequence of the conductor spacer on the line length can be calculated according to the formula. The installation sub-span sequence is: 36 - 60 - 54 - 66 - 54 - 66 - 54 - 66 - 51 - 60 - 33. Because the number of conductor spacers installed on the conductor within the span is 10, plus the starting point and the ending point of the conductor, 11 sub-spans will be generated. In the sub-span sequence 36 - 60 - 54 - 66 - 54 - 66 - 54 - 66 - 51 - 60 - 33, the first data 36 is the distance between the first conductor spacer and the starting point of this section of the conductor, and the last data 33 is the distance between the last conductor spacer and the ending point of this section of the conductor.

The number of installations of the double pendulum anti-vibration device on the line length is divided into 3 groups, and the 3 groups of double pendulum anti-vibration devices are symmetrically distributed with the three installation points of 2 / 9L, 1 / 2L, and 7 / 9L as the centers; among them, the distribution spacing is 6 meters; Let j be the remainder of k / 3 and i be the integer part of k / 3; When j = 0, the installation quantity of the double-pendulum anti-vibration devices in the 1st, 2nd, and 3rd groups is all i; When j = 1, the installation quantity of the double-pendulum anti-vibration device in the 1st group is i, the installation quantity of the double-pendulum anti-vibration device in the 2nd group is i + 1, and the installation quantity of the double-pendulum anti-vibration device in the 3rd group is i; When j = 2, the installation quantity of the double-pendulum anti-vibration device in the 1st group is i + 1, the installation quantity of the double-pendulum anti-vibration device in the 2nd group is i, and the installation quantity of the double-pendulum anti-vibration device in the 3rd group is i + 1.

[0026] In a specific implementation manner of the embodiment of the present invention, according to the wire length and the installation number of the double-pendulum anti-vibration devices on the wire length, the installation positions of the double-pendulum anti-vibration devices are arranged, and it further includes: When the wire length L is greater than 700m, the four-point arrangement principle is adopted. The installation number of the double-pendulum anti-vibration devices on the wire length is divided into 4 groups, and the 4 groups of double-pendulum anti-vibration devices are symmetrically distributed with the four installation points of 2 / 9L, 7 / 16L, 9 / 16L, and 7 / 9L as the centers; wherein, the distribution spacing is 6 meters; Let j be the remainder of k / 3 and i be the integer part of k / 3; When j = 0, the installation quantity of the double-pendulum anti-vibration devices in the 1st, 2nd, 3rd, and 4th groups is all i; When j = 1, the installation quantity of the double-pendulum anti-vibration device in the 1st group is i, the installation quantity of the double-pendulum anti-vibration device in the 2nd group is i + 1, the installation quantity of the double-pendulum anti-vibration device in the 3rd group is i, and the installation quantity of the double-pendulum anti-vibration device in the 4th group is i; When j = 2, the installation quantity of the double-pendulum anti-vibration device in the 1st group is i, the installation quantity of the double-pendulum anti-vibration device in the 2nd group is i + 1, the installation quantity of the double-pendulum anti-vibration device in the 3rd group is i + 1, and the installation quantity of the double-pendulum anti-vibration device in the 4th group is i; When j = 3, the installation quantity of the double-pendulum anti-vibration device in the 1st group is i + 1, the installation quantity of the double-pendulum anti-vibration device in the 2nd group is i + 1, the installation quantity of the double-pendulum anti-vibration device in the 3rd group is i, and the installation quantity of the double-pendulum anti-vibration device in the 4th group is i + 1.

[0027] In this embodiment, since L = 600m, the three-point arrangement principle is selected. According to the above three-point arrangement principle, it can be calculated that 5 double-pendulum anti-vibration devices are macroscopically arranged at the wire length of 133m, 4 double-pendulum anti-vibration devices are macroscopically arranged at the wire length of 300, and 5 double-pendulum anti-vibration devices are macroscopically arranged at the wire length of 467m. Symmetric micro-arrangements are made with these three installation points as the centers; wherein, the meaning of the micro-arrangement spacing of 6 meters is as follows: Since the number of double-pendulum anti-vibration devices installed at the first installation point is 5, the double-pendulum anti-vibration device in the middle of these 5 double-pendulum anti-vibration devices is located at a line length of 133 m, and the two on the left and right are successively located at line lengths of 121 m, 127 m, 139 m, and 145 m. The number of double-pendulum anti-vibration devices installed at the second installation point is 4, and the central position of these 4 double-pendulum anti-vibration devices is at a line length of 300 m. The positions of these 4 double-pendulum anti-vibration devices are successively located at line lengths of 291 m, 297 m, 303 m, and 309 m. The number of double-pendulum anti-vibration devices installed at the third installation point is 5, which is odd similar to the first group. Then the double-pendulum anti-vibration device in the middle of these 5 double-pendulum anti-vibration devices is located at line lengths of 455 m, 461 m, 467 m, 473 m, and 479 m.

[0028] Through the above analysis, the sub-span sequence of the double-pendulum anti-vibration devices installed on the line length is obtained as: 121-6-6-6-6-146-6-6-6-146-6-6-6-6. Briefly analyze this sequence: The first data 121 is the distance between the first installed double-pendulum anti-vibration device and the starting point of the line length. The second data 6 is the distance between the second double-pendulum anti-vibration device and the previous one, that is, 127 - 121 = 6. The sixth data 146 is the distance between the sixth double-pendulum anti-vibration device and the fifth one, that is, 291 - 145 = 146. The remaining data can all be replicated by the method introduced above.

[0029] IV. Calculate the sub-span sequence of the combined layout of conductor spacer dampers and double-pendulum anti-vibration devices In the existing method, transmission project designers often separately give the installation positions of conductor spacer dampers and double-pendulum anti-vibration devices, and construction personnel refer to the installation. This method of separately arranging positions often results in the phenomenon that conductor spacer dampers also need to be installed at the positions where double-pendulum anti-vibration devices are theoretically installed. In practical applications, when this situation occurs, the installation of conductor spacer dampers will be cancelled and the installation of double-pendulum anti-vibration devices will be retained, but it will cause problems such as inaccurate statistics of the number of conductor spacer dampers in the early stage, the purchase quantity, and the unreasonable distance between the conductor spacer dampers and the double-pendulum anti-vibration devices. Therefore, it is necessary to comprehensively consider the installation positions of the conductor spacer dampers and the double-pendulum anti-vibration devices and make a combined layout.

[0030] In this embodiment, the sub-span sequence of the conductor spacer dampers installed on the line length is: 36-60-54-66-54-66- 54-66-51-60-33, The sub-span sequence of the double-pendulum anti-vibration devices installed on the line length is: 121- 6-6-6-6-146-6-6-6-146-6-6-6-6.

[0031] That is, in this embodiment, to solve the problems existing in the prior art, it is necessary to synthesize the above two sub-span sequences into one sub-span sequence, which is convenient for construction personnel to clearly obtain the installation positions of the conductor spacer dampers or double pendulum anti-vibration devices.

[0032] In a specific implementation manner of the embodiment of the present invention, the obtaining of the combined arrangement sub-span sequence of the conductor spacer dampers and the double pendulum anti-vibration devices includes: First, cancel all the conductor spacer dampers within the installation range of each group of double pendulum anti-vibration devices, then adjust the installation positions and quantities of the conductor spacer dampers outside the installation range of each group of double pendulum anti-vibration devices, and finally add marks [] to the sub-spans corresponding to the positions where the double pendulum anti-vibration devices are installed to obtain the combined arrangement sub-span sequence of the conductor spacer dampers and the double pendulum anti-vibration devices. In this embodiment, the added mark is [], and in other embodiments, it can also be other marks different from this embodiment.

[0033] The adjustment of the conductor spacer dampers outside the installation range of each group of double pendulum anti-vibration devices includes: Assume that the maximum sub-span on the wire length L is a and the minimum sub-span is b, then the adjustment method is: If L1 + L2 ≤ a, then remove the No. 1 conductor spacer damper; If L1 + L2 > a and L1 ≥ b, then keep the position of the No. 1 conductor spacer damper unchanged; If L1 + L2 > a and L1 < b, then adjust the No. 1 conductor spacer damper so that L1 = b; Among them, as Figure 2 shown, L1 is the distance between the outermost double pendulum anti-vibration device at the installation point of each group of double pendulum anti-vibration devices and the adjacent No. 1 conductor spacer damper; L2 is the sub-span between the outermost double pendulum anti-vibration device at the installation point of each group of double pendulum anti-vibration devices and the adjacent No. 1 conductor spacer damper (the distance between the No. 1 conductor spacer damper and the adjacent No. 2 conductor spacer damper). In this embodiment, the maximum sub-span a is taken as 66 m and the minimum sub-span b is taken as 25 m.

[0034] According to the above method, the combined arrangement sub-span sequence obtained by the combined arrangement of the sub-span sequence of the conductor spacer dampers installed on the wire length and the sub-span sequence of the double pendulum anti-vibration devices installed on the wire length is: .

[0035] Brief analysis of the above combined arrangement sub-span sequence: The first data 36 and the second data 60 are the sub-spans of the first conductor spacer damper and the second conductor spacer damper installed on the wire length respectively. The data marked with [] are the sub-spans of the double pendulum anti-vibration devices installed on the wire length.

[0036] The 8th data 25 is the sub-span of the 3rd conductor spacer damper installed on the wire length, and the calculation is as follows: The position of the 3rd conductor spacer on the line length is: 36 + 60 + 54 = 150, that is, it is located at 150 m of the line length. The double pendulum anti-vibration device adjacent to the 3rd conductor spacer is the 5th double pendulum anti-vibration device in the first group introduced above, which is located at 145 m of the line length. Then L1 = 150 - 145 = 5. The position of the 4th conductor spacer on the line length is: 36 + 60 + 54 + 66 = 216, that is, it is located at 216 m of the line length. Then L2 = 216 - 150 = 66. Then L1 + L2 = 71 > 66, and L1 = 5 < 25. Then move the position of the 3rd conductor spacer 20 m to the right, so that the distance between the 3rd conductor spacer and the 5th double pendulum anti-vibration device is 25 m, that is, the 8th data 25 in the above combined arrangement sub-span sequence is obtained. At this time, the position of the 3rd conductor spacer on the line length is 150 + 20 = 170, that is, it is located at 170 m of the line length.

[0037] The 8th conductor spacer falls within the installation range of the third group of double pendulum anti-vibration devices, so it is cancelled. The calculation is as follows: The position of the 8th conductor spacer on the line length is: 36 + 60 + 54 + 66 + 54 + 66 + 54 + 66 = 456, that is, it is located at 456 m of the line length. The starting point of the 3rd group of double pendulum anti-vibration devices, that is, the position of the first double pendulum anti-vibration device in the 3rd group, is at 455 m of the line length. Therefore, according to the rules introduced above, the original 8th conductor spacer.

[0038] The sub-spans of the remaining conductor spacers can be replicated according to the above calculation method, and the final actual required combined arrangement sub-span sequence is obtained, which solves the problems of inaccurate statistics of the number of conductor spacers in the early stage and unreasonable distances between conductor spacers and double pendulum anti-vibration devices.
