The invention provides an icing monitoring method of a power transmission line, which comprises the steps as follows: step one, a plurality of ultrasonic wave transceivers (a first ultrasonic wave transceiver, a second ultrasonic wave transceiver, ......, an nth ultrasonic wave transceiver) are arranged around the power transmission line and connected with a main control module, wherein the ultrasonic wave transceivers are positioned on the same circumference and the center of the circumference is positioned on an axis of the power transmission line; step two, the propagation velocities V of ultrasonic waves in the environment are measured by the main control module; step three, the main control module sequentially controls each ultrasonic wave transceiver to transmit and receive an ultrasonic wave and simultaneously records the time of each ultrasonic wave transceiver from transmitting the ultrasonic wave to receiving the ultrasonic wave; and step four, the main control module calculates the icing thickness value of the power transmission line corresponding to each ultrasonic wave transceiver according to the recorded time. The accuracy and the correctness of icing monitoring thickness detection of the power transmission line are effectively improved.
Description
technical field [0001] The invention belongs to the field of cable monitoring, and in particular relates to a method for monitoring icing of power transmission lines. Background technique [0002] my country's meteorological environment is changeable, and ice disasters occur from time to time. The ice rain or ice and snow frozen on the transmission line will gradually form an ice shell with a cross section approximately oval or egg-shaped on the transmission line. The icing of transmission lines can only be formed in a specific natural environment. When the temperature and humidity of the air reach certain conditions, icing can be formed. When the temperature and humidity meet the conditions, the amount of icing depends on the wind speed. When there is no wind or light wind, only extremely thin ice can be formed. When the wind speed reaches a certain speed, the ice on the line will accumulate and thicken. Severe icing will cause damage to transmission lines, even interrupti...
