[0002] At present, the line design based on the 3D modeling technology of transmission lines is becoming more and more mature. When simulating the connection between the V-type suspension insulator string and the tower hanging point in the 3D software, a fixed standard insulator string model is often used. Since the tower hanging point position is related to the tower type, the string hanging point of the insulator string model cannot be accurately connected with the tower hanging point, and the actual insulator string cannot be accurately expressed after the length adjustment, which cannot meet the full line calculation requirements in the transmission line design.

[0003] Designing according to the standard insulator string model increases the difficulty and risk of construction. During the on-site construction of the transmission line, the construction personnel replace the hardware or adjust the hole position according to the design value of the transmission line to achieve the purpose of connecting the V-type suspension insulator string with the tower hanging point. However, due to the complex on-site factors and the limited adjustable hardware, the final erection results will deviate from the design value, causing uneven force on the two arms of the V-type suspension insulator string, resulting in a reduction in the life of the insulator string, and even causing the insulator string to break, endangering the safety of line operation, or causing design rework due to on-site adjustments not meeting the design value.

[0068] Specifically, all pole tower hanging points of the insulator string are traversed, and the left and right tower connecting fittings of the insulator string are found through the positions of the pole tower hanging points. The direction vector of the connecting fittings is calculated through the two connection points of the tower connecting fittings, the left arm is the va vector, and the right arm is the vb vector.

[0069] Step 132, traverse the hardware chain of the insulator string, and determine whether each hardware is a connecting plate hardware according to whether the connection point vector of each hardware is parallel to the direction vector of the left and right tower connecting hardware, until the lowest connecting plate hardware is found;

[0070] Specifically, traverse the hardware chain of the insulator string and find the connection point vector of the hardware. If the connection point vector of the hardware is parallel to both va and vb, then this hardware is the connecting plate hardware of the left and right arms of the insulator string. Traverse in sequence to find the lowest connecting plate hardware.

[0071] Step 133, obtaining the connection fittings connected to each connecting plate fitting according to the connection relationship between each connecting plate fitting and the fitting chain of the insulator string, adding the connection fittings to the corresponding arm fitting chain, and generating the fitting chain of each arm.

[0072] In an optional embodiment of the present invention, step 14 may include:

[0076] Specifically, according to the different hole connections of the PT plates and the DB plates of the adjustment fittings of the fitting chain of each arm, the length of each combination of the adjustment fittings of each arm is calculated.

[0077] Step 152, subtract the length of each arm in the current posture from the length of each combination of the adjustment fittings of each arm to calculate the length difference of each combination of the adjustment fittings of each arm;

[0078] Specifically, assuming that the main hole coordinates of the PT plate and DB plate of each arm in the current posture are pos1(x1, y1, z1), and the auxiliary hole coordinates are pos2(x2, y2, z2), then the coordinate posture difference from the main hole to the auxiliary hole is dir(x, y, z) = pos1(x1, y1, z1) – pos2(x2, y2, z2), and the adjustment length of each auxiliary hole compared to the main hole is dL = Among them, x, y, and z are the coordinate attitude differences from the main hole to the auxiliary hole.

[0079] Step 153, obtaining all corresponding length adjustment combination solutions in the current arm according to the length differences of each combination of the adjustment fittings of each arm.

[0080] like Figure 2 As shown, in an optional embodiment of the present invention, step 16 may include:

[0081] Step 161, according to La=LR-L, calculate the arm length that needs to be adjusted for the single arm;

[0082] Where, LR = (TW-BW) / 2 / sin(β / 2);

[0083] Among them, TW is the distance between the left and right hanging points of the tower, BW is the width of the lowest connecting plate hardware, β is the design value of the opening angle of the insulator string, LR is the actual arm length required for the single arm, L is the arm length of the single arm in the current posture, and La is the length of the single arm that needs to be adjusted.

[0084] In an optional embodiment of the present invention, step 17 may include:

[0085] Step 171 , selecting the length that is closest to the length that needs to be adjusted for the single arm in step 16 from all the length adjustment combination solutions in step 15 as the actual adjustment solution, and obtaining a length-adjusting hardware adjustment combination hardware chain.

[0086] In an optional embodiment of the present invention, step 18 may include:

[0087] Step 181, traverse each adjustment fitting in the fitting adjustment combination fitting chain obtained in step 17 in turn, calculate the translation matrix according to the adjustment length of each adjustment fitting and the direction vector of each arm obtained in step 13, multiply all fitting matrices in the current posture by the translation matrix to obtain all fitting matrices after adjustment, and adjust the length of the substring of the insulator string model.

[0088] Specifically, each adjustment fitting in the fitting adjustment combination fitting chain obtained in step 17 is traversed in sequence, and the matrix of all fittings after length adjustment is calculated according to the following formula:

[0089] transMat=Lc*vc

[0090] FmatJJ=transMat*matJJ

[0091] Among them, transMat is the translation matrix, Lc is the adjusted length of each hardware, vc is the direction vector of the hardware chain, matJJ is the matrix of all hardware in the current posture, and FmatJJ is the matrix of all hardware after length adjustment.

[0092] The direction vector vc of the hardware chain is the direction vector of the tower hardware.

[0093] The following is a description of the specific implementation process of the above method embodiment of the present invention:

[0094] Step 101, traverse all the hardware in the insulator string model of the transmission line, calculate the connection point position according to the hardware matrix of the hardware, if two hardware have the same connection point, then the two hardware are connected, and traverse in sequence to obtain all the connection hardware of the hardware. Then continue to search for subsequent hardware until all the hardware of the insulator string is traversed, and the connection hardware of all hardware can be obtained to determine the hardware chain of the insulator string.

[0095] Step 102, traverse all the pole tower hanging points in the insulator string, find the left and right tower connecting hardware of the insulator string through the position of the pole tower hanging point, calculate the direction vector of the connecting hardware through the two connection points of the tower connecting hardware, the left arm is the va vector, and the right arm is the vb vector. Traverse the hardware chain of the insulator string, find the connection point vector of the hardware, if the connection point vector of the hardware is parallel to both va and vb, then this hardware is the connecting plate hardware of the left and right arms of the insulator string, traverse it in sequence, and find the lowest connecting plate hardware. Then, according to the hardware connection relationship obtained by step 1 for each pole tower hanging point, obtain the connecting hardware, add it to the hardware chain of the arm to which the pole tower hanging point belongs, and traverse the hardware connection hardware in a loop in sequence until the lowest connecting plate hardware is traversed, and the hardware chain of the arm of the insulator string is completed. The hardware chain of all arms of the insulator string is created according to this method.

[0096] Step 103, find the adjustment fittings of the PT plate and DB plate of the upper part of the arm on the insulator through the hardware chain of the arm.

[0097] Step 104, a length is calculated from the different hole connections of the PT plate and the DB plate, and the length of the original hole connection is subtracted to obtain the length difference between each combination and the original posture of the current hardware, thereby obtaining all the corresponding adjustment length combination schemes in the current arm.

[0098] Let the main hole coordinates be pos1(x1,y1,z1), the secondary hole coordinates be pos2(x2,y2,z2),

[0099] Then the coordinate posture difference from the main hole to the auxiliary hole is dir(x,y,z)=pos1(x1,y1,z1)–pos2(x2,y2,z2).

[0100] According to the distance formula Calculate the length difference of each combination of adjustment fittings for each arm.

[0101] Step 105, the minimum width of the connecting plate fitting obtained in step 2 is used as the lower base width BW of the trapezoid, and the distance value from the tower hanging point is used as the upper base width TW of the trapezoid, and the distance value from the tower fitting to the connecting plate fitting is used as the hypotenuse length L of the isosceles trapezoid, and then the actual hypotenuse length LR is calculated according to the isosceles trapezoid principle based on the specified insulator string opening angle design value β / 2, and the difference between LR and the original L is equal to the length La that needs to be adjusted.

[0102] Calculate the arm length to be adjusted from the adjustment angle according to the isosceles trapezoid formula: LR = (TW-BW) / 2 / sin(β / 2);

[0103] Adjusted length difference: La=LR-L.

[0104] Step 106, selecting the adjustment length La closest to step 5 from all the length combination schemes in step 4 as the actual adjustment length, and obtaining a hardware adjustment combination hardware chain for adjusting the length of the insulator string.

[0105] Step 107, using the three-dimensional transformation matrix concept, traverse each adjustment fitting of the fitting adjustment chain obtained in step 6 in turn, calculate the translation matrix transMat = Lc*vc based on the adjusted length Lc of each adjustment fitting and the direction vector vc of the arm obtained in step 2, multiply all fitting matrices from the tower fitting to the adjustment fitting by the translation matrix transMat to obtain the final matrix of the fitting, until all the adjustment fittings are traversed, the transformation matrix of all the fittings can be calculated, thereby achieving the angle adjustment effect of the "V" type suspension insulator string.

[0106] Calculate the direction vector of the arm in the current posture by connecting the first topological point of the tower fitting in the scene at the position ptJJFirst(a1,b1,c1) and the second topological point in the scene at the position ptJJSecond(a2,b2,c2).

[0107] The direction vector vc of the arm is normalized

[0108] The translation vector of the hardware is obtained by adjusting the length Lc of each hardware adjustment

[0109]

[0110] According to the three-dimensional translation vector vtTransJJ, the secondary coordinates are introduced, that is, the four-dimensional translation vector

[0111]

[0112] Then the final transformation matrix of the hardware is

[0113] The above embodiment of the present invention automatically selects a suitable hardware combination and adjusts the hole position, which can effectively solve the problem that the "V" type suspension insulator string and the tower hanging point cannot be accurately connected according to the designed opening angle. The method described in the above embodiment of the present invention can effectively improve the efficiency, accuracy and convenience of transmission line design, reduce construction difficulty, reduce construction risks, and reduce the probability of design rework.
