The invention discloses a lab simulation test system and method for a tower tilt online monitoring apparatus and solves the problem that there is a pressing site demand for an apparatus that may truly simulate tilting of a power transmission tower and for testing and evaluating the tower tilt online monitoring apparatus before mounting. The system comprises a simulation power transmission tower (1), a tower tilt online monitoring apparatus (10) is disposed on the simulation power transmission tower (1), a left footing of the simulation power transmission tower (1) is arranged on a left lift platform (6), and a right footing of the simulation power transmission tower (1) is arranged on a right lift platform (2); by adjusting the left lift platform (6), a rise L1 to a height is implemented, by adjusting the right lift platform (2), a rise L2 to a height is implemented, and calculating is performed to obtain a tilt L1-l2 of the simulation power transmission tower (1). The practicality of a tower tilt online monitoring system is effectively improved.
Description
technical field [0001] The invention relates to an accuracy comparison system for on-line monitoring devices of transmission lines, in particular to an accuracy comparison system for on-line monitoring devices for tower inclination and a monitoring method thereof. Background technique [0002] When the transmission line passes through the goaf, the tower will be tilted due to uneven geological settlement, which will change the tension at both ends of the conductor, cause the sag of the conductor to decrease, and even break the line. At present, the on-line monitoring of tower inclination of transmission lines mostly adopts on-line tower inclination monitoring devices with dual-axis inclination sensors. There is an urgent need for a device that can truly simulate the inclination of transmission line towers on-line to test and evaluate the on-line tower inclination monitoring device before installation. Contents of the invention [0003] The present invention provides a labo...
