Problems solved by technology

[0005] 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 very inconvenient to use the wired method to drag the wires for a long time, which has a certain degree of danger. , It is also more troublesome to check the nuclear phase results

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0024] A phase nuclear instrument with a base station service function includes a sending device and a receiving device, and the sending device and the receiving device are respectively connected to an insulating rod. The installation location is as figure 1 As shown, the sending device is installed on the A-phase line of the known three-phase phase, and the receiving device is installed on any one of the remote phases (A, B, C) to be tested, and the two communicate through SMS.

[0025] The specific process of SMS communication is as follows: the user sends a phase verification command to the mobile phone number of the receiving device through a mobile phone text message, and the receiving device se...

Abstract

The invention relates to a phase check meter with a base station service function and a phase check method. The phase check meter comprises a sending device and a receiving device, wherein each of the sending device and the receiving device is connected with an insulating rod, the sending device is mounted on a known phase-A line, the receiving device is mounted at optional one of remote to-be-checked phases, and the sending device and the receiving device are communicated through short messaging service. The phase check meter registers a good operational performance during trial operation. A great number of trial operation data indicate that the phase check meter with the base station service function developed therein is used for high-voltage phase check through the short messaging service and is high in phase check accuracy and practicality and capable of enhancing operational safety greatly.

Description

technical field [0001] The invention belongs to the field of distribution network operation, and relates to a phase verification instrument, in particular to a phase verification instrument and a phase verification method with a base station service function. Background technique [0002] In the power system, whether the phase sequence is consistent is directly related to whether it can be connected to the grid, and the positive or negative phase sequence also affects the rotation direction of the motor. At present, voltage transformers are generally used to measure high-voltage systems, which is very inconvenient to use. In urban planning and construction, the urban distribution network lines are complex, some early-constructed residences and community lines are not well planned, and the drawings in the reconstruction process are incomplete, etc., which have many impacts on urban planning and construction, so measure the phase sequence and straighten out the current lines ...
