Low-altitude power line swing monitoring device

Abstract

The invention provides a low-altitude power line swing monitoring device and is applicable to the technical field of power system monitoring. The low-altitude power line swing monitoring device is characterized in that one end of a tension spring is fixedly connected with a pole support frame; a hooking connector is fixedly connected with the other end of the tension spring, and is hooked to a power line; one end of a connecting rod structure is connected with the other end of the tension spring; a potentiometer comprises a movable electric brush; the other end of the connecting rod structure is connected with the movable electric brush; the two ends of a power supply are connected with the potentiometer to form a loop circuit with the potentiometer; the tension spring stretches or contracts under the swing effect of the power line to form deformation, and the tension spring drives the movable electric brush to move through the connecting rod structure in the process of being deformed; an AD (analog / digital) sampling circuit collects current signals of the loop circuit and converts the current signals into digital signals; a transmission port is connected with a remote alarm device; a monitoring processor receives the digital signals and transmits the digital signals to the remote alarm device through the transmission port. The low-altitude power line swing monitoring device has the advantages that the structure is simple, the mounting is convenient, and the swing situation of the power line can be monitored in real time.

Description

technical field [0001] The invention relates to the technical field of power system monitoring, in particular to a low-altitude power line swing monitoring device. Background technique [0002] Existing transmission lines are usually installed on poles and towers in an overhead manner. For rural low-voltage power lines, due to the height setting of poles and the selection of wiring paths, power lines often shuttle between woods or bamboo forests. [0003] Due to weather changes, tree branches or bamboo branches are often entangled on power lines due to strong winds. On the one hand, it is easy to conduct electricity through tree branches or bamboo branches in rainy days, causing safety hazards to pedestrians on the road; Swing, excessive wind force may even cause wire breakage or tower toppling, causing great economic losses to the power supply system. [0004] In the existing technology, manual road patrol is often used for inspection, which consumes a lot of manpower and ...
