REMOTE MONITORING DEVICE FOR DISPOSAL CONDUCTOR CONDITION OF THE OVERHEAD TRANSMISSION LINE

摘要

The invention relates to electric power engineering and can be applied for monitoring the condition of overhead transmission line (OHL). Technical result of the invention is the higher monitoring reliability and timely detection of unacceptable condition of conductor in controlled OHL span. The device monitors the condition of OHL conductor (1) and comprises power block (2), ultrasonic or laser range meter (3), unit (4) for wireless data transmission to remote terminal, and processing block (5). Block (5) is connected with range meter (3) and unit (4). Range meter (3) is oriented towards earth or other facilities located under conductor (1). Unit (4) is executed in the form of interface node between block (5) and common cellular telephone channel. Processing block (5) is connected with ice signaling indicator (7), temperature sensor (8) of conductor (1) and current sensor (9) of conductor (1). Signaling indicator (7) is executed in the form of transceiver for 10 encoded high-frequency signals which is connected via linear interface to conductor 1 through connection node 11, and via digital interface to block 5. Such design of signaling indicator 7 enables to equip the device with receiver for 12 standard time signals, eg. satellite global positioning system signal receiver connected to processing block 5.
