Embodiment Construction
[0050] The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings.
[0051] A kind of 500kV transformer substation soft wire blanking length mathematical model calculation method of the present invention comprises the following steps,
[0052] Step S01: Analyzing the physical structure of flexible conductors, insulators and fittings and the connection mode of flexible conductors as input parameters;
[0053] Step S02: Determine the sag value of the soft conductor according to the needs of the site construction, and calculate the horizontal stress through the simplified sag inversion formula ;
[0054] Step S03: Analyze and calculate the resultant force T0 on the U-shaped hanging rings on both sides of the suspension iron frame, and judge whether it is less than the breaking load [T0] of the U-shaped hanging rings. If yes, go to step S04; if not, go to step S02;
[0055]Step S04: Use the catenary method ...
