Tension real-time measuring device and tension real-time measuring method

Abstract

The invention provides a tension real-time measuring device and a tension real-time measuring method. The device comprises stand columns which are arranged on the same straight line and an impact cable which is arranged on the stand columns. A spanning frame arranged below the impact cable comprises parallel carrier cables and a net movably arranged between the carrier cables. The two ends of the impact cable and the two ends of the carrier cables are provided with fixing pillars and tension adjusters respectively. The measuring system comprises a height measuring instrument, a scene recorder, a theodolite and a real-time tension measuring instrument. Compared with the prior art, the tension real-time measuring device and the tension real-time measuring method can measure the tension instant change data of the spanning frame after the spanning frame is subjected to line breaking impact, when the spanning frame is arranged on a transmission line in an erected mode, spanning frames meeting requirements can be selected according to measurement data, and the damage to original power lines or ground barriers due to line breaking impact of the transmission line can be avoided.

Description

technical field [0001] The invention relates to a tension measurement device, in particular to a measurement device and a measurement method for real-time measurement of tension changes. Background technique [0002] With the accelerating pace of electric power development, the power grid has also developed rapidly, the operating voltage level of the power grid system has been continuously improved, and the network scale has also been continuously expanded. Power grid construction has become the main direction of power construction, and a strong smart grid will be built in an all-round way. [0003] With the increase of overhead transmission lines, more and more new overhead transmission lines cross the original power lines and ground obstacles. In order to ensure the normal operation of the original power lines and ground obstacles, it is necessary to 1. Protective devices are erected above ground obstacles to ensure that the newly-built overhead transmission lines have a ...

Problems solved by technology

However, since the momentary tension of this suspension type spanning frame will increase after being impacted by the broken line, the sag will also increase, and whether the rope will not break after the tension increases and whether the sag can ensure the safety of the rope after the increase of the tension To provide sufficient safety distance for power lines and ground obstacles to be crossed, it is necessary to provide a measuring device to measure the instantaneous change of tension and sag, so as to verify the existing theoretical formula

[0005] The traditional tension measuring device can only measure the static tension or the tension with a very low speed of change, and cannot measure the instantaneous tension change of the suspension spanning frame after being impacted by a broken wire in real time.
