The invention discloses a loose coupling transformer and an underwater wireless electric energy transmission system employing the same, the loose coupling transformer comprises two annular coils arranged from inside to outside, each annular coil comprises columnar magnetic core windings uniformly arranged along the circumference, wires wound outside the magnetic core windings are connected in series, the two ends of the columnar magnetic core winding of each annular coil are connected together through an annular magnetic core, and a gap is formed between the two annular coils. The transmittingcoil and the receiving coil of the loose coupling transformer adopt modular design, the loose coupling transformer is light in weight, and design of different power levels can be achieved; the magnetic field is restrained by the magnetic core, so that eddy-current loss of the electromagnetic field in seawater is reduced; and a magnetic circuit symmetric design is adopted, so that the anti-offsetcapability is relatively high, and the requirement on the butt-joint precision of the coupling mechanism is low.

    本发明公开了一种松耦合变压器及采用该变压器的水下无线电能传输系统,包括由内至外布置的两个环状线圈,所述环状线圈包括沿圆周均匀设置的柱状磁芯绕组,各磁芯绕组外缠绕的导线串联连接,每个环状线圈的柱状磁芯绕组的两端分别通过环状磁芯连接在一起,两个环状线圈之间有间隙。本发明松耦合变压器的发射线圈与接收线圈采用模块化设计,松耦合变压器质量轻,且可实现不同功率等级设计;磁场由磁芯约束减小了电磁场在海水中的涡流损耗;采用磁路对称设计,具有较强的抗偏移能力,且对耦合机构对接精度要求低。
