Abstract： |
This invention relates to an intelligent data collection and protection integral system used in high-middle voltage power devices characterizing in that the intelligent data collection part is composed of a digit circuit to realize the on-line sampling of data and the high speed CAN communication function of an upper processor and finish the complicated data on-line pretreatment function matched with enough resources, the protection part is composed of an analog circuit to finish the over voltage test and alarm of the master circuit high level voltage, the analog circuit voltage test has no process period so as to realize zero time delay over voltage protection, the split-plug design for a voltage adjustment circuit suits different levels. The circuits of two parts are integrated in a same system to use the voltage signal source together, configure the systematic resources reasonably and the system and the upper processor are connected by fibers. |
