A kind of inter-board bus plug-in test method

Abstract

The present invention provides an inter-broad bus plug-in test method. Power consumption values of a plurality of primary source loops are detected to determine whether each primary source loop is normally operated, if all the primary source loops are normally operated, the power source values of a plurality of secondary source loops are detected to determine whether each secondary source loop is normally operated, and if all the secondary source loops are normally operated, the function test is performed and the inter-board bus plug-in test is completed. Therefore, the method realizes inter-broad bus plug-in electrifying detection, is accurate in detection, does not need manual intervention and simplifies the detection program.

Description

technical field [0001] The present application relates to the technical field of plug-in detection, in particular to an inter-board bus plug-in testing method. Background technique [0002] The DC control and protection device is the core of the HVDC transmission system, and its performance directly determines the operation of the DC project and the safety of the DC equipment. Among them, the DC protection is used to protect the DC equipment of the converter station, and quickly remove the open circuit fault or abnormal operating equipment in the system under fault or abnormal conditions to prevent it from causing damage or interfering with the normal operation of other parts of the system. The multi-processor board assembly based on the plug-in for bus communication between control and protection boards is the core component of HVDC control and protection. [0003] In the prior art, the plug-in test of the inter-board bus must go through the neutral resistance test of the ...

Problems solved by technology

The inter-board bus plug-in is relatively complicated, and there are many primary power and secondary power circuits. In the case of no electricity, some power circuits using isolated power sources have small static impedance. Only empirical values ​​can be used to judge whether the power circuit is abnormal.

And after the inter-board bus plug-in is charged, the abnormality of the primary power supply and the secondary power supply is detected by manually observing the measured values ​​of the primary power supply and the secondary power supply, and touching the main components. The hidden danger of a fault developing into a larger fault

Moreover, the functional test of the inter-board bus plug-in requires reliable inter-board communication capabilities and manual intervention to conduct a complete test, and manual observation of the results is prone to large errors
