Embodiment 1

[0066] When cracks appear on high voltage cables, such as Figure 6 shown, perform the following steps:

[0067] S11, data acquisition: the data acquisition module 32 arranged on the intelligent inspection robot 3 collects the real-time status data of the high-voltage cable in real time, and transmits the real-time status data to the data processing module 34;

[0068] S12, data processing: the data processing module 34 compares the real-time state data with the standard data transmitted by the memory module 36, and generates a comparison result and sends it to the main control module 35;

[0069] S13, early warning judgment: the main control module 35 performs early warning processing on the comparison result, when the size and shape of the crack exceed the early warning threshold, generate early warning information and enter step S14, and when the size and shape of the crack do not exceed the early warning threshold, enter step S17;

[0070] S14, alarm judgment: the main co...

Embodiment 2

[0075] When the surface temperature of the high-voltage cable is abnormally high, such as Figure 7 shown, perform the following steps:

[0076] S21, data acquisition: the data acquisition module 32 arranged on the intelligent inspection robot 3 collects the surface temperature data of the high-voltage cable in real time and transmits the data processing module 3;

[0077] S22, data processing: the data processing module 34 compares the high-voltage cable surface temperature data with the standard temperature transmitted by the memory module 36, and generates a comparison result and sends it to the main control module 35;

[0078] S23, early warning judgment: the main control module 35 performs early warning processing on the comparison result, when the surface temperature of the high voltage cable exceeds the early warning threshold, generates early warning information and enters step S24, and when the surface temperature of the high voltage cable does not exceed the early wa...

Embodiment 3

[0084] Compared with Embodiment 1, this embodiment has a different rail structure, such as Figure 8 As shown, the cross section of the guide rail body 21 is circular, including a support layer 211, an elastic material layer 212 and a wear-resistant layer 213 arranged sequentially from the inside to the outside. Same guide groove.

[0085] The concave guide groove can effectively avoid snow covering the guide device 22, so that the intelligent inspection robot 3 can better run along the extension direction of the guide device 22 on the flexible guide rail 2, and improve the stability of the intelligent inspection system.

Abstract

The invention discloses an intelligent inspection system for a high-voltage cable. The intelligent inspection system comprises guide rail brackets (1), a flexible guide rail (2), an intelligent inspection robot (3) and a central control system (4), wherein the guide rail brackets (1) are fixedly arranged on a pylon and are used for supporting the flexible guide rail (2); two ends of the flexible guide rail (2) are fixed on two adjacent guide rail brackets (1) separately and the flexible guide rail (2) is used for providing the intelligent inspection robot (3) with support and guide; the intelligent inspection robot (3) is arranged on the flexible guide rail (2) and is used for monitoring the high-voltage cable in real time, generating warning information or alarm information when a potential safety hazard appears and transmitting the warning information or alarm information to the central control system (4); and the central control system (4) is used for converting the warning information of a warning signal, converting the alarm information into an alarm signal and feeding back the signals to a manager. According to the intelligent inspection system for the high-voltage cable, thepotential safety hazard in the high-voltage cable can be timely discovered, so that the security and the stability of a high-voltage line are improved and the inspection cost is reduced.

Description

technical field [0001] The invention relates to the field of power transmission line detection, in particular to an intelligent inspection system for high-voltage cables. Background technique [0002] High-voltage lines usually refer to transmission lines that carry voltages above 10KV (including 10KV). In the wild, overhead lines carried by iron towers are often used for transmission. At present, the inspection of outdoor high-voltage cables generally adopts the following two methods: 1) Manual inspection along the line tower by tower; 2) Helicopter inspection. The first method of patrol inspection is labor-intensive, expensive and has high risk; the second method is restricted by meteorological factors, and the helicopter cannot stay at a fixed point for a long time, and the cost is high. [0003] The application number is 201120413583.2, which discloses a high-voltage line inspection robot, including a walking device, a functional module and a detection module. The walk...
