Problems solved by technology

[0006] (1) Inspection scheme 1) can only roughly simulate short-circuit / ground faults, and is not suitable for inspection of batch fault indicators
[0007] (2) Compared with the inspection scheme 1), the inspection scheme 2) has been greatly improved, but the console and the main station system are not integrated together. The pass / failure of the fault indicator inspection needs manual judgment, and the automatic inspection cannot be realized. Require

Abstract

The invention relates to a full-automatic closed-loop testing system for a fault indicator. The full-automatic closed-loop testing system comprises a console with an embedded simulator station, a testing unit and a monitoring unit, wherein the console, the testing unit and the monitoring unit are sequentially connected to form a closed loop, the testing unit comprises a voltage source and a current source which are respectively connected with the console and the fault indicator to be tested, the fault indicator to be tested is connected with the monitoring unit, and the console is connected with the fault indicator to be tested. Compared with the prior art, the full-automatic closed-loop testing system has the advantages of high automation level, good flexibility, high testing efficiency and the like.

Description

technical field [0001] The invention relates to a fault indicator testing device, in particular to a closed-loop full-automatic testing system for the fault indicator. Background technique [0002] The current inspection methods for distribution line fault indicators generally include: [0003] 1) Separate current source and voltage source. The separate current source and voltage source are used to meet the conditions of short circuit fault / ground fault, and the indicating unit forms a local alarm indication or sends alarm information to the monitoring unit, and the monitoring unit then sends the alarm information to the master station system and displays it. The advantage of this approach is that it is simple and easy to implement. All existing resources are used to build a test environment, which is applicable to the initial R&D stage. [0004] 2) The test device is formed by integrating the current source and the voltage source, but the console is separated from the ana...
