Ice disaster prevention method for suppressing wire torsion through distributed suspended heavy hammers

Abstract

The invention provides an ice disaster prevention method for suppressing wire torsion by distributed suspended heavy hammers. The method comprises the following steps: S1, acquiring parameters of a power transmission line, wherein the parameters comprise an equivalent icing thickness and a line span length of the power transmission line; S2, calculating eccentric torque of eccentric ice of wing-shaped icing formed by the power transmission line under the condition that the power transmission line is not twisted; S3, determining the total torque of the suspended heavy hammers according to the suspended weight mass and the shape of the suspended heavy hammers, wherein the total torque is equal to the eccentric torque; and S4, determining the number and the distribution spacing of the suspended heavy hammers, and then suspending the suspended heavy hammers according to the distribution spacing. The power transmission line can be effectively prevented from waving under the wind power condition so that the power transmission line is prevented from twisting due to waving to form uniform icing and the icing is non-uniformly coated on one side. The wing-shaped icing of the power transmission conductor naturally falls off under the action of natural wind power so that the icing disaster of the power transmission line is prevented, the stable operation of the whole power grid system is further ensured, and the production and life loss of the society caused by the icing of the power transmission line is avoided.

Description

technical field [0001] The invention relates to an anti-icing method, in particular to an ice disaster prevention method for suppressing the twisting of a wire by a distributed suspension weight. Background technique [0002] Icing of transmission lines seriously endangers the safe operation of the power grid. The icing of transmission wires is a gradual process. During the icing process, the ice layer first grows on the windward side. If the wind direction does not change sharply, the ice thickness on the windward side will gradually increase. When the ice on the windward side reaches a certain thickness , when the weight of icing on the wire is enough to make the wire twist, the wire will twist; in the process of continuous icing, the wire shows that the icing will continue to grow, and finally a circular or oval icing will be formed on the wire. Generally, wires with small diameters are covered with ice in a circular shape, and wires with large diameters are elliptical. ...

AI Technical Summary

Problems solved by technology

The icing on the transmission wire exceeds the weight that the wire can bear, causing the tower to collapse, and the icing on the transmission line seriously endangers the safe operation of the power grid. At the same time, it brings great inconvenience to people's production and life
