摘要（英）：

The utility model discloses an electric signal injection and reception device used for the high voltage parallel reactor winding fault detection. The device comprises a signal injection and protection circuit, a voltage sensor, a capacitive voltage divider and a protection shell. The protection shell is grounded, and the signal injection and protection circuit and the voltage sensor are arranged on a casing pipe of a reactor. The signal injection and protection circuit is connected with an injection interface of a signal terminal in the protection shell via a core wire of a coaxial cable, and the injection interface is connected with the protection shell via a first switch. The voltage sensor is connected with the capacitive voltage divider, and the capacitive voltage divider is connected with a detection interface of the signal terminal in the protection shell via the core wire of the coaxial cable. The detection interface is connected with the protection shell via a second switch, and an earth wire of the coaxial cable is connected with the protection shell.
