The invention provides a method for calculating installation positions of a rotary spacer and a double-pendulum anti-galloping device, and the method comprises the steps: building a data structure of the spacer, and analyzing a core code of an anti-galloping device installation calculator; the operation difficulty is low, and only several steps of simple operation and parameter setting are needed; the calculation time is short, for a technical improvement project with the short project time, only one day needs to be spent on independently calculating the installation distance between the rotary spacer and the double-pendulum anti-galloping device, and the calculation can be completed only within one minute by applying the program; the error rate is low, due to the fact that repeated logical operation exists in the calculation process, errors are prone to occurring when manual calculation and Excel auxiliary calculation are adopted, and 100% accuracy can be achieved on the premise that the program is set to be correct.
Description
technical field [0001] The invention relates to the field of power transmission and transformation construction, in particular to a method for calculating the installation positions of a rotating spacer bar and a double-pendulum anti-dancing device. Background technique [0002] In recent years, various regions have carried out large-scale technological transformation projects. In some of the projects, the damping spacer between the conductors is replaced by a rotary spacer and a double-pendulum anti-dancing device to achieve the purpose of anti-dancing control of the transmission line. [0003] There are two commonly used calculation methods in construction, manual calculation and Excel-assisted calculation. Manual calculation is slow, the error rate is high, and the modification is difficult. Although Excel-assisted calculation overcomes many shortcomings of manual calculation, its calculation efficiency has not been significantly improved for repetitive and complex logi...
