Embodiment Construction

[0034] The detection device of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0035] Aiming at the characteristics and detection requirements of the transmission line wire sag monitoring device based on laser distance measurement, the present invention proposes a detection device for a laser sag monitor, which uses the principle of optical reflection to realize a long-distance measurement path, and by measuring the intensity of the laser signal , frequency and phase are detected to realize laser signal weakening compensation; by analyzing the measurement error, the source of the error is found and the error value is determined; the measurement data is processed through the virtual instrument to obtain accurate detection results.

[0036] Such as figure 1 The shown test system of the present invention includes: a standard measuring instrument (total station) 1, a device under test 2, a near-end fixed platform 3, ...

Abstract

The invention provides a detection apparatus used for a laser arc sag monitor. The apparatus comprises a test system and a data processor. The test system comprises a standard measuring device and a light compensation device; the standard measuring device and the light compensation device are successively arranged on a horizontal mobile track; the data processor comprises a data input module, a data calculation module and an examination result output module; and the data processor receives and processes data input by the test system. The detection apparatus provided by the invention is simple in structure and high in measurement precision and improves the test efficiency under the condition that test detection requirements are met.

Description

technical field [0001] The invention relates to state monitoring of power transmission lines, in particular to a detection device for a laser sag monitor. Background technique [0002] Transmission line on-line monitoring devices have been widely used in power grid status management, disaster prevention and mitigation, and smart grid construction. However, the development time of transmission line on-line monitoring devices is relatively short. At present, there are generally problems such as quality and reliability of the devices, which seriously restrict The popularization and application of transmission line condition monitoring system. [0003] In order to ensure the network quality of the devices, the State Grid Corporation has established a technical laboratory for power transmission and transformation equipment condition monitoring in the China Electric Power Research Institute, and some provinces and cities have also started the construction of transmission line cond...
