Abstract

A signal detection apparatus (1) includes an acquisition assembly, a charging capacitor (3), an AC-DC conversion module (4), a detection capacitor (5), and a pair of voltage detection interfaces (6). The acquisition assembly is coupled to a target line (11) to acquire a surge signal in the target line (11). The acquisition assembly includes at least two acquisition coils (2) connected in series. Two ends of the charging capacitor (3) are respectively coupled to the acquisition assembly, and the charging capacitor (3) is adapted to be charged by the acquisition assembly. The AC-DC conversion module (4) is connected in parallel to the charging capacitor (3) to convert an AC voltage output by the charging capacitor (3) into a DC voltage. The detection capacitor (5) is coupled to the AC-DC conversion module (4) to be charged by the AC-DC conversion module (4). The pair of voltage detection interfaces (6) are respectively coupled to two ends of the detection capacitor (5) to detect a voltage across the detection capacitor (5).
