Problems solved by technology

There are also video and other systems used in the construction process of existing transmission line wiring, but only video can not get the distance value of the wire to the ground and the distance between the crossing object, that is, it cannot provide a value, and it cannot be used to control the wiring construction tension
The video can only provide a relatively macro image, but it can't do anything about the value
[0003] And the friction coefficient of the pay-off block is not a fixed value, and it is difficult to obtain an accurate value. The height of the crossing object and the ground cannot be accurately known according to the pulling force. It is inaccurate to judge the distance of the crossing object only based on the pulling force for tension control

Abstract

The invention discloses an intelligent tension stringing monitoring device for an overhead electric transmission line, which comprises a data wireless receiving and processing unit, a pulley wireless angular transducer, a traction measuring device and a tension measuring device. The pulley wireless angular transducer is used for measuring the angle of a conducting wire and a horizontal plane at apulley on a rod tower; the traction measuring device is used for measuring the traction of a tractive rope of the electric transmission line; the tension measuring device is used for measuring the tension of an outlet conducting wire of a tensioning machine; and the pulley wireless angular transducer, the traction measuring device and the tension measuring device are all connected with the data wireless receiving and processing unit wirelessly through a wireless receiving-transmitting device. The data wireless receiving and processing unit can receive the information of the wireless angular transducer, the tension information of the tension measuring device and the traction information of the traction measuring device, and further draws a sag curve of the conducting wire according to the information and the parameters of a know ground and a spanning object, so as to monitor the sags of all shelves or all important shelves in real time.

Description

technical field [0001] The invention relates to a tension stringing device for an overhead transmission line, in particular to an intelligent monitoring device and a monitoring method for the tension stringing of an overhead transmission line. Background technique [0002] At present, during the tension-strung construction process of overhead transmission lines, it is necessary to ensure that the distance between the ground wire and the crossing object meets the safety requirements. The height of objects, etc., are observed by eyesight, and the values ​​provided are not very accurate. Therefore, it is necessary to further improve the accuracy of the distance of crossing objects, reduce human errors, and ensure the safety of wiring construction. There are also video and other systems used in the construction process of existing transmission line wiring, but only video can not get the distance value of the wire to the ground and the distance between the crossing object, that i...
