Three-remote automatic test device for power distribution terminal

Abstract

The invention discloses a three-remote automatic test device for a power distribution terminal. The three-remote automatic test device comprises a digital signal controller, a current source assembly, a voltage source assembly, a remote signaling assembly, a remote control assembly, a data interface, a current sampling assembly and a voltage sampling assembly. The three-remote automatic test device for the power distribution terminal can automatically test functions and performances such as analog quantity acquisition, digital quantity acquisition and control quantity output of the power distribution terminal according to the test scheme. A test result is derived through the data interface, and a test report is formed. According to the three-remote automatic test device for the power distribution terminal, the automation degree of the test process is high, test efficiency is improved, and the test cost is reduced.

Description

technical field

[0001] The invention relates to power electronic equipment technology, in particular to a three-remote automatic test equipment for power distribution terminals. Background technique

[0002] Distribution automation plays a key role in improving power supply reliability and power quality. The implementation of distribution automation depends on a large number of distribution terminals installed on site. These terminals mainly have the functions of analog quantity acquisition, digital quantity acquisition and control quantity output, referred to as telemetry, remote signaling, and remote control (three remotes). Whether the three-remote function and performance of the terminal can meet the technical standards is the key factor for the success of the distribution automation project. Therefore, power companies need to conduct network access tests on distribution terminals before implementing distribution automation. Random inspections will also be carried out d...
