Abstract

The invention provides an automatic detection system for fault indicators for a distributing line. The automatic detection system for the fault indicators for the distributing line comprises an automatic test module, an output control device, a data acquisition unit and a control acquisition unit. The output control device, the data acquisition unit and the control acquisition unit are respectively connected with the automatic test module by computer communication lines. According to the automatic detection system for the fault indicators for the distributing line provided by the invention, the real-time acquisition of the action states of the fault indicators is realized. The amplitude of a tested alternating voltage signal and the amplitude of an alternating current signal can respectively reach 10kV and 2kA, and actual signals of the line can be more accurately simulated. Moreover, the automatic detection system for the fault indicators for the distributing line is high in degree of automation, test efficiency and safety.

Description

technical field [0001] The invention relates to a detection system, in particular to an automatic detection system for a distribution line fault indicator. Background technique [0002] Although a large number of line fault indicators are used in power distribution lines, and there are a large number of manufacturers, there is no unified indicator standard and technical specification at home and abroad. They are not the same, and the technical level of the products is very different. When the line fails, the correct rate of the indicator action is low, and it is prone to false alarms and false alarms. [0003] In 2010, the State Grid Corporation promulgated the enterprise standard "Q / GDW436-2010 Technical Specifications for Distribution Line Fault Indicators", which uniformly stipulated the functions, performance indicators and test methods of fault indicators, and stipulated a variety of functions and performance test items. Although the advanced fault indicator detection...
