Embodiment 1

[0023] Embodiment 1: as figure 1 As shown, a remote wireless phase verification system for power lines based on 5G communication includes a reference host and a host to be tested. The reference host and the host to be tested are respectively connected to the line under test and the line to be tested through a signal collector. , the signal collector achieves data transmission with the receiving host through 5G, the reference host and the host to be tested are both connected to the Beidou ground-based augmentation system, and the reference host is connected to the host to be tested, such as image 3 and Figure 4 As shown, both the reference end host and the test end host include a microprocessor, a power supply module, a GPRS wireless module, an LCD display module, a GPS module, and a first radio frequency transceiver module, the first radio frequency transceiver module is wirelessly connected to the signal collector, and the GPS The module is wirelessly connected to the Beid...

Embodiment 2

[0028] Embodiment 2: a kind of verification phase method of the remote wireless phase verification system of power lines based on 5G communication, comprising the following steps:

[0029] S1. First, the signal collector on the line under test collects the signal collector on the line to be tested and the signal collector on the line to be tested respectively collects the voltage positive zero-crossing signal on the line under test and the voltage positive zero-crossing signal on the line under test, and then the signal collector Send the collected signal to the reference end host and the test end host through the second radio frequency transceiver module;

[0030] S2. The host at the reference end and the host at the test end start timing after receiving the second pulse signal sent by the GPS module, and end when receiving the positive zero-crossing signal of the voltage on the line under test and the line under test, and obtain the line under test and Time difference inform...

Abstract

The invention provides a power line remote wireless phase checking system and method based on 5G communication. The system comprises a reference end host and a to-be-tested end host which are respectively connected with a tested line and a to-be-tested line through a signal collector. The reference end host and the to-be-tested end host are both connected with the Beidou ground-based augmentation system, and the reference end host is connected with the to-be-tested end host. The reference end host and the to-be-detected end host are used for monitoring voltage zero crossing point signals on a tested line and a to-be-tested line respectively, then the voltage zero crossing point signal acquisition time on different lines is compared with the time difference between the pulse per second, and then the phase detection result on the to-be-tested line is obtained through calculation. Remote wireless phase checking is integrally realized, and the operation is simple.

Description

technical field [0001] The present invention relates to the technical field of power line phase verification, in particular to a 5G communication-based remote wireless phase verification system and method for power lines. Background technique [0002] At present, the phase verification of the switchgear is mainly carried out on the secondary side, but because the secondary side of the switchgear uses the test hole of the live indicator for the phase verification, and the main function of the live indicator is to indicate whether the switch cabinet is charged, and it is not a standard phase verification Therefore, there is no uniform standard for the connection circuit of the live indicator test hole of the switchgear from different manufacturers, different periods, and different standards, which will cause different degrees of phase shift in the live indicator test hole of the switchgear of different manufacturers, and the voltage is low. Distortion, mixed lines, etc., cause...
