High-voltage line polling device based on GPS

Abstract

The invention discloses a high-voltage line polling device based on a GPS (global positioning system). The polling device comprises a barrel, deicing devices, clamping devices, driving devices, a weight reduction device, a solar cell panel and a protection device; the deicing devices are symmetrically fixed at two ends of the barrel, the clamping devices are arranged in the barrel; the number of the clamping device is nine, and every three clamping devices are uniformly distributed at an inner all of the barrel in a ring, and three rows of clamping devices are equidistantly arranged; a base isfixed at the bottom of the barrel; one driving device is fixed at one of four corners at the bottom of the base, and the orientation of the driving device located at one end of the base is opposite to that of the driving device at the other end of the base. The high-voltage line periodic polling device based on the GPS disclosed by the invention is fast in polling speed and high in efficiency, the tiny fault in the high-voltage line can be detected so as to prepare in advance, and the device is low in power consumption, the solar energy is used for supplying power, the accurate positioning can be realized through the GPS after detecting the fault, thereby realizing fast overhauling.

Description

technical field [0001] The invention relates to the technical field of high-voltage line fault detection, in particular to a GPS-based high-voltage line inspection device. Background technique [0002] High-voltage lines usually refer to transmission lines that transmit voltages above 10kV (including 10kV). According to GB / T 2900.50-2008, definition 2.1, high voltage usually does not include 1000V. The voltage levels of high-voltage transmission lines in China are generally divided into: 35kV, 110kV, 220kV, 330kV, 500kV, 750kV, etc. [0003] High-voltage overhead transmission lines generally use steel-cored aluminum stranded wires. Under the combined action of huge variable tension, bending stress caused by vibration, and long-term fatigue caused by rapid changes in temperature, the material of the transmission line will become brittle. It will cause surface damage under the ground, which will inevitably lead to cracks and broken strands of high-voltage overhead transmissio...

Problems solved by technology

[0003] High-voltage overhead transmission lines generally use steel-cored aluminum stranded wires. Under the joint action of huge variable tension, bending stress caused by vibration, and long-term fatigue caused by rapid changes in temperature, the material of the transmission line will become brittle. It will inevitably cause surface damage to the high-voltage overhead transmission line, which will inevitably cause cracks and broken strands, which seriously threaten the wire itself, its transmission and transformation equipment, and personal safety. Therefore, it is of great significance to carry out automatic inspection and fault diagnosis of transmission lines. Existing fault diagnosis, usually after the line is obviously damaged and unusable, then manually narrow the scope and gradually check to find out the fault point. This method is inefficient and cannot prevent problems before they happen. Therefore, we propose a GPS-based high-voltage line inspection device
