技術說明

一種電流方向檢測模組，主要係包含一轉換單元、一電橋單元及一運算單元。該轉換單元係電性連接該電橋單元，該電橋單元係電性連接該運算單元，該轉換單元係感測一待測電流並輸出一轉換電流，該電橋單元係輸入該轉換電流並輸出二電橋電壓，該運算單元係輸入該電橋電壓並輸出一運算電壓。可另設一放大單元供放大該運算電壓，一整形單元供調整該運算電壓之波形，一比較單元供比較該運算電壓之值。藉此，可檢測電力系統故障電流方向，協助判斷電力系統之短路故障發生位置。 A current direction detecting module is disclosed. The current direction detecting module comprises a conversion unit, an electrical bridge unit and an operating unit. The conversion unit is electrically connected to the electrical bridge unit which, in turn, is electrically connected to the operating unit. The conversion unit detects a to-be-tested current and outputs a conversion current. The electrical bridge unit receives the conversion current and outputs two electrical bridge voltages. The operating unit receives the two electrical bridge voltages and outputs an operating voltage. The current direction detecting module may further comprise an amplifier unit amplifying the operating voltage, a shaping unit adjusting the waveform of the operating voltage, and a comparison unit doing comparison of the voltage value of the operating voltage. In this arrangement, a direction of a failure current in a power system can be detected to find out the exact location of an error.
