Problems solved by technology

[0004] Disadvantages of manual calculation method: 1. Undetectable data input and recording errors will occur during the calculation process; 2. Many human errors in manual calculation will affect the accuracy of calculation results; 3. The accuracy of manual calculation results is uncertain; 4. The work efficiency is low, and there is a possibility of duplication of work; 5. A large number of employees cannot independently complete comprehensive calculations covering angle conversion, trigonometric functions, interpolation calculations, and square root, etc., and cannot calculate support data based on design drawings and measurement data value, making the choice of personnel to carry out the work extremely limited

Embodiment 1

[0050] Such as figure 1 , figure 2 As shown, the intelligent calculation system for overhead transmission lines includes a sag measurement calculation module, a sag design value calculation module, a foundation torsion calculation module, an entire base tower inclination calculation module, a headroom distance calculation module, a line length calculation module, a line Tower database, calculated design value reference database, calculated value result comparison database;

[0051] The sag measurement value calculation module is used to calculate the ground wire sag measurement value and output the calculation result;

[0052] The sag design value calculation module is used to calculate the design sag value of the measurement file;

[0053] The base torsion calculation module is used to calculate the torsion value of the measuring tower;

[0054] The inclination calculation module of the whole base tower is used to calculate the inclination of the measuring tower;

[0055...

Embodiment 2

[0062] The difference from Embodiment 1 is that when the sag measured value calculation module is selected, the vertical height from the suspension point of the input wire to the center of the horizontal axis of the instrument, that is, the measured value, is calculated by the method of the end of the file, the method of the middle of the file or the method of the outside of the file The sag of the ground wire; the calculation formula of the gear end method is as follows:

[0063]

[0064] Among them, a is the measured value; L is the span of the observation gear; α1 is the tangential angle of the guide and ground line (the elevation angle is positive, and the depression angle is negative); α2 is the suspension point tangent angle (the elevation angle is positive, and the depression angle is negative);

[0065] The calculation formula of file method is as follows:

[0066]

[0067] Among them, L is the span of the observation file; L 0 is the horizontal distance between...

Embodiment 3

[0073] Different from Embodiment 1, the sag design value calculation module is selected, and the design sag calculation formula is as follows:

[0074] f=f 100 ·L 2 10 -4 +cosβ (4)

[0075] Among them, L is the gear distance, β is the height difference angle of the wire suspension point; f 100 is the erection sag of the 100-meter span;

[0076] The calculation formula of β is as follows:

[0077] β=arctan(h' / L) (5)

[0078] Among them, h' is the height difference of the suspension point, and L is the gear distance;

[0079] When the temperature is t, f 100 The calculation formula is as follows:

[0080]

[0081] Among them, f1 is the sag corresponding to the temperature t1; f2 is the sag corresponding to the temperature t2; t is the actual temperature measured; The full ten temperature.
