A New Alignment Instrument Based on the Principle of Sound Wave Transmission

变电站二次系统检修和施工过程涉及大量电缆对线工作。因此,研究电力系统中电缆对线仪的现状,针对现有对线仪器存在安全系数低、准确率不高和操作复杂等不足,提出一种基于声波传输原理的新型对线仪。利用声波传输安全无干扰的特征,介绍一种新型对线仪器,在待测电缆首端发射声波信号,通过接收不同线芯末端的声波信号频率,标识出待识别的电缆。结果表明,该新型对线仪具有安全、高效、稳定等优点,拥有良好的推广价值。

In the process of maintenance and construction of secondary system of substation, a lot of cable alignment work is involved. This paper studies the current situation of the cable to wire instrument in the power system. In view of the shortcomings of the existing cable to wire instrument, such as low safety factor, low accuracy and complex operation, a new type of wire instrument based on the principle of acoustic transmission is proposed. Based on the characteristics of safe and non-interference of acoustic transmission, this paper introduces a new type of line instrument, which transmits acoustic signal at the first end of the cable to be tested, and identifies the cable to be identified by receiving the frequency of acoustic signal at the end of different cores. The new type of alignment instrument has the advantages of safety, high efficiency and stability, and has a good promotion value.
