Abstract

The invention relates to the technical field of power systems, and particularly discloses a cable alignment device, which comprises: atransmitter which is connected with a tested cable and used for emitting a sound wave signal with a specific frequency to the tested cable; and a receiver which is connected with the tested cable, and is used for collecting the sound wave signal with the specific frequency transmitted by the tested cable, and analyzing the collected sound wave signal with the specific frequency to determine the line sequence relation between the transmitter and the receiver. The transmitter which comprises a transmitting end expansion module, the transmitting end expansion module is connected with the tested cables and used for providing expanded sound wave signals with specific frequency when the number of the tested cables is increased. The receiver comprises a receiving end expansion module, and the receiving end expansion module is connected with the tested cables and used for collecting the expanded sound wave signals of the specific frequency when the number of the tested cables is increased. According to the cable alignment device provided by the invention, the implementation efficiency of alignment is improved.

Description

Technical field [0001] The present invention relates to the technical field of power systems, and more particularly to a cable counter. Background technique [0002] During the construction of the power system substation, the quantity of the secondary cable is large, and the line workload is large. It is easy to happen, and there may be short circuits and open circuits. These problems are light, which affects work efficiency, extension of the period, and the operation of the device, resulting in power grid safety incident. At present, most of the ducts are based on the common end of the reference core, and the pulse signal or potential signal is used as the transmission medium. The method determines that the reference core is based on the method of the traditional multimeter, and the transmission medium is in the cable core with the protection voltage. There is security risks, which is very likely to cause judgmental interference to the station relay protection device. And the nu...
