Line fault detecting system and method capable of achieving real-time interaction of three-phase data

Abstract

The invention discloses a line fault detecting system and method capable of achieving real-time interaction of three-phase data. The system comprises a plurality of groups of fault indicators mounted on three-phase lines and a master monitor station, and every group of fault indicators comprise three fault indicators which are mounted on the three phases of the three-phase lines respectively and communicated with one other synchronously; by means of the synchronous communication, the fault indicator on any phase of the three-phase lines can obtain the synchronous data of the corresponding two fault indicators on the other two phases at the same time and comprehensively determines whether the corresponding phase gets into fault through the synchronous data of the three-phase lines; the three-phase fault indicators are communicated with the master monitor station. The line fault detecting system and method capable of achieving the real-time interaction of the three-phase data has the advantages of improving the fault detecting accuracy, avoiding data transmission losses and being also applicable to the condition other expanding projects requiring the three-phase interaction data need performing on overhead lines.

Description

technical field [0001] The invention relates to a line fault detection system and method capable of real-time interaction of three-phase data. Background technique [0002] The overhead fault indicator is connected to the phase line of the distribution overhead line. By detecting the current and voltage of the distribution line, it can judge the short circuit and ground fault, and locate the fault section accordingly. In recent years, some manufacturers have introduced fault indicators with communication functions. The fault indicators have a built-in short-distance wireless communication module, and a dedicated data collector is set as the communication terminal. The data collector communicates with the indicator through the short-distance wireless communication module. The wireless public network communication module or wired way communicates with the main station, that is, the fault indicator itself has no long-distance wireless communication function, and the data inform...
