System and method for measuring conductor sag based on inclination angle difference method

Abstract

The invention discloses a system and a method for measuring conductor sag based on an inclination angle difference method. The system comprises a measuring device A1, a measuring device A2 and a host module, wherein the measuring device A1 comprises a single-axis inclination angle sensor I, an MCU processor I, a data storage device I and a wireless transceiver I; the measuring device A2 comprises a single-axis inclination angle sensor II, an MCU processor II, a data storage device II and a wireless transceiver II; and the host module comprises a wireless transceiver III and a host. According to the system and the method provided by the invention for measuring the conductor sag based on the inclination angle difference method, a sensor non-linear error caused by the temperature is made up by mutual compensation of data measured by the two devices, and a more accurate sag value can be acquired.

Description

technical field [0001] The invention relates to a wire sag measurement system and method based on an inclination differential method. Background technique [0002] The sag of overhead transmission lines is an important index for the design and operation of transmission lines. Too large or too small may cause serious safety hazards. [0003] In addition, in recent years, due to the increase in power load, many existing transmission lines have increased the maximum allowable temperature of the conductor from 70 degrees Celsius to 80 degrees Celsius in order to improve the power transmission capacity. The existing methods for measuring the sag value are generally Using a single sensor, the measurement accuracy of a single sensor is easily affected by the installation process and operating temperature. The sensor has a nonlinear error to temperature, and a single sensor cannot compensate well. Contents of the invention [0004] The purpose of the present invention is to over...
