Remote digital kernel phase system

Abstract

This invention discloses a remote digital phase-check system including a reference end device and a mobile end device, in which, the reference end device includes a GPS receiving adapter and a host, the mobile device includes a GPS receiving converter, a mobile communication host, a phase detector, a handheld test device and a mobile phone, the devices of the two ends are placed in two different places and phase information between them is transferred through the current phone network resources distributed extremely wide, and the transfer among sub-devices especially those of the mobile end is by radio transmission technology so as to increase the safety and stability greatly.

Description

technical field [0001] The present invention relates to electric power nuclear phase technology, in particular, relates to a remote, digital nuclear phase system. Background technique [0002] Today, with the rapid growth of electricity demand, the power industry has developed rapidly, and the capacity of the power grid has continued to increase. The power production and power transmission departments have put forward higher requirements for the stability of power system operation. In actual power operation, the measurement of phase difference is very important. Newly built, rebuilt and expanded substations and transmission lines, as well as after the line is overhauled and before power is delivered to users, must undergo a three-phase circuit phase verification test 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 and the correct phase is the guarantee of safe electricity use....

AI Technical Summary

Problems solved by technology

If the nuclear phase is wrong, the load will be burnt down, and the line will be blacked out in severe cases, resulting in huge economic losses

[0003] At present, most of the nuclear phase equipment of three-phase power lines at home and abroad are wired, and only support local and short-distance applications, and cannot support remote nuclear phase, which has obvious geographical limitations.
