Abstract

The invention discloses a wireless nuclear phase instrument, which consists of a master machine, an X slave machine and a Y slave machine, wherein both the two slave machines comprise an inductive voltage sensor, an amplifier and a wireless communication module; the master machine comprises a display module, an MCU control module, a key and a wireless communication module; the slave machines also comprise an AD sampling module and an MCU control module; the wireless communication modules of the master machine and the slave machines all adopt bidirectional communication data transmission; a nuclear phase method of the wireless nuclear phase instrument comprises that: a communication protocol of an addressing mode is set in the MCU control module of the master machine, the master machine sends a signal acquisition command, the X slave machine and the Y slave machine simultaneously acquire voltage signals on a tested line, the master machine receives the data acquired by the X slave machine and the Y slave machine in time division mode, and the MCU control module calculates the phase and amplitude data and displays the data on the display module. The wireless nuclear phase instrument has the advantages of flexible and safe use, high reliability in signal transmission, signal receiving accuracy and reliable test results.

Description

technical field [0001] The invention relates to a phase verification device for phase verification and phase sequence verification of power transmission lines and substations, in particular to a wireless phase verification instrument with two-way wireless data communication. technical background [0002] Before the three-phase line of the power transmission line is connected, the phase verification and phase sequence verification are carried out; before the parallel operation of the transformers, the group identification is carried out, that is, the phase verification test is carried out to ensure correct wiring and safe power transmission. [0003] The phase nuclear meter is a device used to detect and indicate the correct phase relationship between two charged parts under the same rated voltage and frequency. At present, phase verification instruments used for phase verification and phase sequence verification of power transmission lines and transformer group identificatio...
