Embodiment
[0071] Assuming that the entire insulator string is 12m long and is composed of 80 insulators, each insulator length L=0.15m, a set of on-site conductor wind deflection data is calculated respectively by the monitoring method of the present invention and the conventional method before, and comparative analysis is carried out:
[0072] The comparison of monitoring method of the present invention and conventional method in table 1
[0073]
[0074] It can be seen from Table 1 that the windage monitoring method of the transmission conductor of the present invention can more accurately reflect the actual windage of the conductor.

The invention discloses a ZigBee-based system for monitoring the wind drift of a power transmission line on line, which comprises a ZigBee wireless wind drift detector, a rod tower monitoring sub-machine, a general packet radio service (GPRS) communication module and a monitoring center, which are connected in turn, wherein the rod tower monitoring sub-machine and the GPRS communication module are connected with a power supply module respectively; and the rod tower monitoring sub-machine is connected with a wired wind drift detector. In a method using the system for monitoring, the actual wind drift condition of an insulator string of the power transmission line can be obtained accurately by acquiring the wind drift angles of the topmost and bottommost insulators of the insulator string of the power transmission line in real time or fixed time and by quantitative calculation and qualitative analysis, and thus, the most direct and efficient monitoring of the wind drift of the insulator string of the power transmission line is realized.
Description
technical field [0001] The invention belongs to the technical field of on-line monitoring of the state of power transmission and transformation equipment, and relates to an online wind deflection monitoring system for transmission conductors, in particular to an online wind deflection monitoring system for transmission conductors based on ZigBee, and also relates to a monitoring method using the system . Background technique [0002] Affected by natural conditions, overhead transmission lines will have many kinds of disasters, and wind deflection flashover of transmission line insulators is one of the more serious disasters. The wind deflection angle of the wire suspension insulator string refers to the angular deviation of the suspension insulator string caused by the wind acting on the insulator string and the wire, and the wind load of the wire causes the suspension insulator string to deflect. The main cause of the wind deflection flashover accident is that the deflecti...
