Embodiment Construction

[0031] figure 1 A test system (detection platform) for implementing the detection method of the present invention is shown, and the system includes: a server, a network switch, a complete set of fault indication devices for the distribution line under test, a characteristic waveform generator, and the like. During testing, each device plays a different role:

[0032] Server: On the one hand, it simulates the master station of power distribution automation, which is used for the collection, information storage, data processing and analysis of data sent by the remote communication terminal of the fault indication complete set; on the other hand, it is used for parameter setting of the characteristic waveform generator , Adjust the output of the characteristic waveform and record the output waveform.

[0033] Network switch: provide a network access method for the communication between the power distribution line fault indication complete set, the characteristic waveform generat...

Abstract

The invention discloses a distribution line fault indication integrated equipment function and performance detection method. The method comprises a function test portion and a performance test portion, wherein the function test portion comprises six items, i.e., a fault alarm function test, a fault alarm reset function test, an event record function test, an anti-error alarm test, an information loss prevention test and a working mode test and the like; and the performance test portion comprises two items, i.e., a current acquisition precision test and a fault report timeliness test. When the method is provided by the invention is applied to detection work, various function performance parameters of whole distribution line fault indication integrated equipment can be detected in a comprehensive and rapid manner so that the safe, reliable and stable operation of the equipment in a power distribution network can be ensured; and at the same time market behaviors and product technical indicators are standardized so that technical references are provided for the purchase, acceptance and daily regular maintenance of equipment of this type.

Description

technical field [0001] The invention belongs to the technical field of power distribution automation systems, and in particular relates to a detection method for the function and performance of a power distribution line fault indication complete set. Background technique [0002] Whether in cities or in rural areas, the requirements for power supply reliability are getting higher and higher. Since the complete set of fault indication devices has the characteristics of fast finding and locating faults in distribution lines, this type of equipment is more and more widely used in power distribution systems. At present, there are various types of complete sets of fault indication devices for power distribution lines on the market, and the quality of the product functions is even more uneven. The distribution line fault indication complete set is generally composed of a fault sensor (ie, a fault indicator) and a terminal with remote transmission function (ie, a remote communicat...
