Power line gravity characteristic monitoring device

Abstract

The invention discloses a power line gravity characteristic monitoring device, comprising a base A (1) and a spring (18), characterized in that: the two ends of the spring (18) are respectively fixed on the base A (1) and the base On B (15); metal rod A (14), metal rod B (20) and metal rod C (23) are installed on one side of the base B (15), and permanent magnets A (16) are respectively installed on the top thereof , permanent magnet B (22), permanent magnet C (6); on one side of base A (1) fixedly connect metal pipe A (9), metal pipe B (7), metal pipe C (2), respectively Reed switch A (12), reed switch B (21), and reed switch C (13) are installed on its top; Bellows (11) are installed on the outside of (2). The invention can monitor whether the wire is seriously covered with ice and whether it is broken in the shortest time, and helps to restore the operation of the faulty line faster.

Description

technical field [0001] The invention relates to the technical field of line monitoring equipment for power systems, in particular to a gravity characteristic monitoring device for power lines. Background technique [0002] In the power system, because the high-voltage power lines of the system are often under the action of external forces and other natural disasters, the power lines will be broken and iced, which will bring harm to the safe operation of the system. In the case of ice, the line has no means to reflect the actual situation. In the prior art, manual line inspection or observation is usually used. Since most of the lines are in the wilderness, when a line breaks, it is necessary to manually search for the broken line. The labor intensity of the staff is high, time-consuming and laborious, and cannot Damaged lines can be identified faster, resulting in more accurate fault handling. If the line is covered with ice, because the lines are not all at the same altit...

Problems solved by technology

In the prior art, manual line inspection or observation is usually used. Since most of the lines are in the wilderness, when a line breaks, it is necessary to manually search for the broken line. The labor intensity of the staff is high, time-consuming and laborious, and cannot Faster identification of damaged lines, resulting in more accurate fault handling

If the line is covered with ice, because the lines are not all at the same altitude, the ice condition of each section of the line is different in the initial stage of line icing. It is necessary to rely on personnel to inspect section by section, or use telescopes for long-distance observation. Measure the icing status of the line to judge whether to carry out ice-melting treatment. The workload of the staff is huge, and there is no unified judgment standard for the degree of icing; It is inconvenient to find and observe the line icing, which leads to the untimely melting of ice, and then the failure to deal with the fault in time
