Problems solved by technology

The phasing work is carried out according to the order of the commander. The high-voltage operator fixes the high-voltage lead wire on the insulating rod, and the length is appropriate. When the high-voltage wire is used to touch the high-voltage power point with the insulating rod, the movements are coordinated, and the two take care of each other to avoid mistakes and cause danger. , the problem with this method is that for high-voltage lines, especially for phase detection of high-voltage overhead lines, two devices are required to be in contact with two wires at the same time, and it is inconvenient to use the wired method, and it has certain risks
[0007] The above wireless phasing instruments can only complete point-to-point phasing. With the continuous development of the power system, in order to adapt to the complexity of the future power line network, it is necessary to design and manufacture an online power frequency phase monitoring device

Description

technical field [0001] The invention relates to the field of grid identification equipment, in particular to an online power frequency phase monitoring device. Background technique [0002] In the field of power distribution, phase verification refers to the use of instruments or other means to check whether the phases and phase sequences of two power sources or loops are the same. That is, in the operation of actual power, the measurement of phase difference. Newly built, rebuilt and expanded substations and transmission lines, as well as after the line is overhauled and before power is sent to users, must conduct three-phase circuit phase verification tests to ensure that the phase sequence of the transmission line meets the requirements of the user's three-phase load. The phase sequence is consistent. [0003] According to the investigation of the inventor, it is found that the existing phasing methods mainly have the following forms: [0004] 1. Local wired phasing: T...
