This utility model relates to the field of current transformer technology and discloses an environmentally friendly anti-interference current transformer, including two current transformer housings. Current transformer assemblies are disposed inside the two current transformer housings, and bases are installed on the bottom surfaces of both current transformer housings. This environmentally friendly anti-interference current transformer facilitates disassembly of the current transformer housings by setting a fixing plate on the upper surface of the housings and connecting them with bolts, while also using a snap-fit ​​mechanism between the two housings. This facilitates the recycling of the internal components. During use, the secondary winding coil is spirally and uniformly wound, reducing the distributed capacitance and inductance of the winding and enhancing the overall anti-interference capability. As the cable passes through the middle area of ​​the current transformer housing, it is guided by a limiting rope to be as close as possible to the center of the iron core, reducing the problem of uneven magnetic field distribution within the iron core caused by eccentricity and improving the anti-interference capability.

This invention discloses a novel inductor coil and circuit. The novel inductor coil includes at least one pair of inductor units. Each pair of inductor units consists of a first inductor and a second inductor with identical structures. The first inductor is connected in series at one end of the load, and the second inductor is connected in series at the other end of the load. The center-to-center distance between the first and second inductors is D, where D ≥ 0. The first and second inductors are symmetrically distributed along the centerline of D / 2. Both the first and second inductors are frameless arc-shaped hollow coils with an arc θ satisfying 0 < θ ≤ π and curvature k2 ≥ 0; when θ = π, D > 0. The inductor provided by this invention does not form a common-mode inductor, which can effectively reduce electromagnetic interference and external electromagnetic radiation. It can also be used on the main power path, and its heat dissipation performance is improved, with flexible adjustment of inductor parameters.
