Description

technical field [0001] The invention relates to a GSM-based remote intelligent phase nuclear instrument and a phase nuclear method. Background technique [0002] During the actual operation of the power system, it is often necessary to carry out phase verification work. Before substations and transmission lines are put into operation after new construction, reconstruction and expansion, and before the transmission line is overhauled and delivered to users, a three-phase circuit phase verification test must be carried out. , to ensure that the three-phase phase sequence of the power equipment put into operation is consistent. [0003] At present, domestic high-voltage power line phase verification mainly includes three methods: local wired phase verification, local wireless phase verification and remote wireless phase verification. [0004] In the case of local wired phase verification, 4 people are required, 1 person is the commander, 2 people wear insulating boots and glov...

AI Technical Summary

Problems solved by technology

[0004] In the case of local wired phase verification, 4 people are required, 1 person is the commander, 2 people wear insulating boots and gloves as the nuclear phase operator, and 1 person records the instrument. The phase nuclear work is carried out according to the command of the commander, and the high-voltage The lead wire is fixed on the insulating rod, and the length is appropriate. When the insulating rod is used to lead the high-voltage wire to touch the high-voltage power point, the actions should be coordinated, and the two people should take care of each other to avoid mistakes and cause danger. The problem with this method is that the cable is very long. It is very inconvenient to use, has a certain degree of danger, and can only be measured at a short distance

The measurement process is cumbersome, and there may be human error (such as the measurement personnel misread or misheard the data, etc.), etc.

[0007] From the above analysis, it can be seen that there are many deficiencies in the existing nuclear phase technology methods, which cannot meet the requirements of intelligent nuclear phase in the future.
