An integrated inductor and a power conversion module including the integrated inductor are provided. The integrated inductor includes a magnetic core, the magnetic core including two cover plates, two side columns and two central columns between the two side columns, and two windings wound around the two central columns respectively, forming two inductors. Each operating current flowing through the two windings includes a corresponding high-frequency current component, a phase difference between the high-frequency current components of the operating currents flowing through the two windings is 180 degrees.

Integrated inductor and a power conversion module including the integrated inductor

A warning device for preventing underground cables against accidental excavation comprises an optical fiber vibration sensor having a mode recognition function, a signal processing unit, a wireless communication unit and a power supply unit, wherein the signal processing unit is connected to the optical fiber vibration sensor, the wireless communication unit and the power supply unit, and the optical fiber vibration sensor is installed within a set range of a cable and is used to monitor vibration signals around the cable, so that once a behavior possibly endangering the cable occurs, an alarm is given out in time to reduce power transmission and transformation accidents. Compared with the prior art, the warning device has the advantages of low false alarm rate, rapid response and accurate localization region.
