Abstract

The invention relates to a remote on-line sag monitoring device of an overhead high voltage power transmission circuit, in particular to a sag monitoring device of the power transmission circuit. The sag monitoring device of the power transmission circuit resolves the problems that an existing sag monitoring device of the power transmission circuit is low in measurement accuracy, large in size, inconvenient to use and install and the like, and is composed of a landmark arranged at the maximum sag position on the power transmission circuit and a measurement device arranged on a power transmission circuit tower. The measurement device comprises a machine shell, a single-chip microcomputer, an infrared sensor and a GPRS module are arranged in the machine shell, the infrared sensor is connected with the input end of the single-chip microcomputer and used for measuring the distance between the infrared sensor and the landmark and the included angle between the connecting line of the infrared sensor and the landmark and the horizontal line, and the GPRS module is connected with the output end of the single-chip microcomputer. The single-chip microcomputer works out the first maximum sag and the second maximum sag according to the distance, between the infrared sensor and the landmark, measured by the infrared sensor and the included angle, between the connecting line of the infrared sensor and the landmark and the horizontal line, measured by the infrared sensor in combination of half of the known distance between two towers through the Pythagorean theorem and the trigonometric function, then calculates the average value of the first maximum sag and the second maximum sag and obtains the maximum sag. The sag monitoring device of the power transmission circuit is high in measurement accuracy and small in size.

Description

Power transmission line sag monitoring device
Technical field
The present invention relates to the remote online sag monitoring equipment of aerial high-voltage power transmission line, be specially power transmission line sag monitoring device.
Background technology
It is the important measures ensureing overhead transmission line safe operation that power transmission line sag detects.Power transmission line sag refers to the vertical distance of any point and this some distance two suspension point lines on pole line.There is the problems such as measuring accuracy is low, volume large, use installation inconvenient in existing power transmission line sag monitoring device.
Summary of the invention
