Problems solved by technology

Constrained by measurement technology and harsh line conditions, the current icing monitoring of transmission lines is mainly based on the monitoring of ice weight and equivalent ice thickness. The monitoring of ice shape is relatively rough, and it is difficult to meet the model correction of ice prediction and prediction. It is difficult to meet the test requirements of aerodynamic parameters of ice-coated conductors

Abstract

The invention relates to icing measuring device comprises a fixing frame and two icing detection units, the two icing detection units are arranged on the fixing frame and located on the two sides of apower transmission wire, and the plane where the two icing detection units are located is perpendicular to the extending direction of the power transmission wire. According to the icing measuring device, a projection contour line is formed on the wire and icing through lasers, reflected light of the contour line is received by a CMOS image receiving unit, spatial coordinates of the contour line can be obtained after signal processing based on the optical triangulation principle, and then wire icing shape information can be obtained accurately. On the basis of the monitored icing shape information, power grid icing pre-warning, pneumatic parameter analysis and other work can be corrected in time, and power grid accidents, disasters and the like caused by icing are effectively prevented.

Description

technical field [0001] The invention relates to the field of transmission line monitoring equipment, in particular to an ice coating measurement device and a measurement method for measuring the ice coating of conductors. Background technique [0002] Icing fault is one of the common transmission line faults, which seriously endangers the safe and stable operation of the power grid. Ice-covered transmission wires can easily lead to faults such as heavy ice overload, galloping, jumping off ice, electrical breakdown tripping, etc., and in severe cases, it will lead to the paralysis of the power grid. In order to reduce or eliminate the impact of icing faults, power grid companies are actively developing icing prediction and forecasting technology, line ice melting technology, and tower line system anti-icing technology. The timely and accurate monitoring of transmission conductor icing data is an important part of all these technologies. [0003] There are three main types o...
