Embodiment Construction

[0041] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0042] see figure 1 , the ice observation method of the present invention comprises the following steps:

[0043] S1: The first ice thickness is measured by the microwave ice sensor 2 installed on the tower. During implementation, the microwave detection signal can be loaded and transmitted through the microwave transmitting antenna, and the transmitted microwave detection signal can be received through more than three microwave receiving antennas, and the dielectric value of the transmission medium can be calculated by the voltage signal of the phase difference of the received microwave detection signal. Constant, through the calculation of the dielectric constant to determine whether the transmission medium is air, water or ice, and through the p...

Abstract

The invention discloses an equivalent ice observation method and system. The method comprises the following steps: measuring a first icing thickness through a microwave icing sensor arranged on a tower; calculating the unit thickness of the first icing thickness equivalent to the reference model wire; and calculating the actual equivalent icing thickness according to the diameter of the actual to-be-measured wire and the unit thickness of the reference model wire. According to the invention, the icing thickness of wires of different models can be rapidly obtained, and the accuracy of icing monitoring in the freezing environment is greatly improved.

Description

technical field [0001] The invention relates to the technical field of ice detection on power transmission lines, in particular to an equivalent ice observation method and system. Background technique [0002] Icing of transmission lines is very common. Ice and snow accumulation on transmission lines will lead to a sharp decline in its mechanical and electrical performance, causing major electrical accidents such as conductor galloping, tower tilting or even collapse, disconnection, and insulator flashover, seriously affecting the safe operation of the power system. The freezing disaster that occurred around the Chinese New Year in 2008 caused large-scale and long-term power outages, causing direct economic losses of more than 150 billion yuan, and at the same time had serious social impacts on industrial and agricultural production and people's lives. Therefore, real-time monitoring of the icing status of transmission lines and deicing work has become a hot research topic ...
