Abstract

The invention discloses an automatic dynamic monitoring digital power transmission line, which includes a first ground wire, a second ground wire, a third ground wire and a main control device; the main control device includes a current sensor, a signal processing circuit, a control chip, Communication circuit, gating circuit and display; current sensor output detection signal; signal processing circuit amplifies the detection signal, analog-to-digital conversion to output standard data signal; control chip receives standard data signal to generate real-time current data; communication circuit remote transmission The real-time current data output by the control chip is sent to the controller; the controller digitally displays the real-time current value according to the real-time current data, and identifies the working fault according to the real-time current data; the gating circuit only controls the first line switch, The second circuit switch and the third circuit switch are cut off in sequence; the display digitally receives the real-time current data output by the control chip and digitally displays the real-time current value.

Description

technical field [0001] The invention relates to the technical field of electric power, in particular to an automatic dynamic monitoring digital power transmission line. Background technique [0002] For ultra-high voltage double-circuit, multi-circuit cross-arm or long-distance parallel erection of multiple lines in the same corridor, and lines with small air gaps at crossing points of ultra-high voltage lines, when one of the out-of-service lines is overhauled , Due to the phenomenon of electromagnetic induction, there will be a large induced voltage and induced current in the outage line. When the transmission line is connected, arc discharge will occur, and the transmission line will be connected, causing burns. [0003] In addition, when the high-voltage equipment in the substation is powered off for maintenance, the transmission line is often used to prevent personal electric shock accidents caused by sudden calls or induced electricity from the equipment being overhaul...
