Problems solved by technology
However, in the process of practical application, since the rotation of the insulator string along the axis is not restricted, it will be difficult to determine the direction of the inclination sensor after a period of operation, resulting in a large error in the calculation of the ice thickness

The embodiment of the invention discloses a method, a device and equipment for monitoring the icing thickness of a tension-resistant tower ground wire and a medium. The method comprises the following steps: acquiring span measurement parameters of the tension-resistant tower ground wire before icing; calculating a vertical span on one side of a sensor according to the span measurement parameter before icing, then obtaining a span measurement parameter after icing of the strain tower ground wire, and calculating the mass per unit length after icing of the ground wire according to the vertical span on one side of the sensor and the span measurement parameter after icing; and finally, according to the span measurement parameters before icing and the mass per unit length after icing, calculating the icing thickness of the strain tower ground wire after icing so as to monitor the icing thickness of the strain tower ground wire. According to the embodiment of the invention, the ice coating thickness of the ground wire can be calculated only by adopting the tension sensor, so that the calculation error of the ice coating thickness is reduced, the accuracy of monitoring the ice coating thickness is improved, and the monitoring, operation and maintenance cost is also saved.
Description
technical field [0001] The invention relates to the technical field of power systems, in particular to a method, device, equipment and medium for monitoring the ice thickness of a ground wire of a tension tower. Background technique [0002] The icing of the transmission line is likely to increase the weight of the ground wire in the line, causing accidents such as dropped wires and disconnected wires. In serious cases, it will cause deflection damage to the ground wire support and cross-arm of the tower, or even collapse the tower, which seriously threatens the safe operation of the transmission line. . Therefore, it is necessary to monitor the ice thickness of the transmission line, and when the ice thickness exceeds the safe value, the deicing work should be carried out. [0003] At present, for the monitoring of the ice coating thickness of the ground wire of the strain tower, it is mainly to install a tension sensor and an inclination sensor at the hanging point of the...
