Cable two-side phase sequence checking device

The utility model relates to the technical field of power system construction, and discloses a cable two-side phase sequence checking device which comprises a signal transmitting device and a signal receiving device, the signal transmitting device is connected to a cable core wire through a transmitting end test wire, and then a core wire on the other side of a cable is connected to the signal receiving device. The voltage on the signal transmitting device is transmitted to the signal receiving device, the corresponding phase line can be judged by detecting the voltage amplitude on each core line, whether the phase sequence is correct or not can be judged by displaying the corresponding color, the phase sequence on one side does not need to be known, the accuracy of the phase sequence of all cables can be obtained at a time, and the detection operation is simple. 本实用新型涉及电力系统施工技术领域，公开了一种电缆两侧相序核对设备，包括有信号发射装置及信号接收装置，通过将信号发射装置通过发射端测试线接到电缆芯线上，再将电缆另一侧的芯线接入信号接收装置，信号发射装置上的电压就会传输到信号接收装置上，通过检测每跟芯线上的电压幅值就能判断出相应的相线，并通过显示
