Problems solved by technology
[0004] The purpose of this invention is to solve the problem that the traditional phase-nucleation instrument has a short distance between phase-nucleation and can only perform phase-nucleation detection when the line is electrified, but cannot verify the phase of the newly-built blackout line to be connected to the power grid.

A wireless phase verification test device for a power outage line, comprising a signal collector a arranged at a phase verification initiation end, a transmitting host, a transmitting clamp, and a signal collector b at a phase nuclear judgment end, a receiving host, a receiving clamp, and signal collectors a, b They are respectively used to collect the voltage information of the live lines at both ends; the transmitting host receives the voltage information collected by the signal collector a, so as to send a high-voltage pulse signal with direction to the transmitting clamp, and the receiving clamp is used to induce the transmitting clamp to send through the power failure line The incoming signal, and transmit the pulse signal with direction generated by the coupling to the receiving host; the receiving host receives the voltage information collected by the signal collector b and the pulse signal transmitted by the receiving clamp, and judges the same phase of the live line at both ends and the power failure line The same phase; the present invention can accurately verify the phases of the power failure line and the live lines at both ends, ensure the successful one-time grid connection of the power failure line, and improve the work efficiency and the safety of engineering construction.
Description
technical field [0001] The invention belongs to the technical field of electric power equipment, and relates to the phase verification technology of power cables, in particular to a wireless phase verification testing device for power outage lines. Background technique [0002] With the continuous development of my country's power grid and the increasing demand for electricity, the construction and maintenance of power grid lines are increasing day by day. Before the newly constructed blackout line or line section is connected to the grid, the blackout line must be connected after the correct phase is verified. However, the previous method cannot guarantee that the phase of the blackout line after construction is consistent with the live running line. Check the phase operation by opening and closing the switch multiple times, so as to judge whether the phase of the power failure line to be checked is correct. If the phase of the line to be connected is wrong, it is necessar...
