DEVICE FOR MEASURING ICE AND WIND LOADS ON OVERHEAD POWER TRANSMISSION LINES

摘要

FIELD: power engineering. SUBSTANCE: device used for simultaneous separate monitoring of ice and wind loads for early detection of ice and prediction of wire dancing has magnetoelastic force sensor suspended between supporting-structure cross-arm and phase-conductor insulator string that functions to check full load on overhead power transmission line. Two nonlinear controllable transducers are connected between magnetoelastic force sensor and two remote-transmission channels with measuring instruments. One of transducers measures ice component of full load and other one, wind component. Transducers are controlled by two magnetic current transformers incorporating adding amplifier and dividing unit. EFFECT: enlarged functional capabilities. 4 dwg
