Electricity taking module and electricity taking device for three-phase cable

The invention discloses a power taking module, which can be arranged for each phase of cable core of a three-phase cable through reasonable structural design, and can continuously obtain electric energy to be supplied to sensor equipment for use due to the fact that the power taking module only takes power for one phase of cable core, so that the requirement of a sensor for continuously monitoring a three-phase cable joint is met. The invention further discloses a power taking device with three power taking modules, and each power taking module can obtain electric energy from the three-phase cable, so that the electric energy required by the work of the sensor can be continuously obtained from the three-phase cable. 本发明公开了一种取电模组，通过合理的结构设计，使得可以针对三相电缆的每一相缆芯设置，由于其仅针对一相缆芯取电，可以持续获取电能供应给传感器设备使用，满足传感器持续对三相电缆接头进行监测的需求。本发明还公开了一种具有三组取电模组的取电装置，每一组取电模组均可以从三相电缆中获取电能，从而可从三相电缆中持续获取给传感器工作所需要的电能。
