Metal plate inductive coil used in harsh environment The utility model relates to a metal steel plate inductive coil used in a harsh environment, which is provided with a conductive coil, which is characterized in that:(1) It is a thin steel wire coil surrounded by a plane formed after the space separation of the steel plate engraving, and is provided with four layers, that is, four steel wire coils arranged in parallel, which are connected in series in turn; An insulating support block is arranged between each ring wire of each steel wire coil (2) An insulating layer is arranged between each layer of steel wire coils (3) A ceramic shell with insulation, high temperature resistance, high acid and alkali is arranged on the outer surface of the four layer coil (4) The shell is provided with a power line (5) The utility model is suitable for inductive coils working in harsh environments, with novel structure, simple application and convenient use. In particular, the utility model has stable working performance and long service life in harsh environments. High frequency and high power adjustable inductance coil device The utility model relates to an inductive coil, in particular to a high-frequency high-power adjustable inductive coil device for a high-power transmitter, which comprises a base plate, a coil group arranged on the base plate and a driving mechanism. The utility model is characterized in that the coil group comprises a fixed coil and a moving coil, and is provided with a fixed skeleton arranged coaxially and a moving skeleton which can rotate around an axis, The fixed coil and the moving coil are composed of N multi strand soft insulated copper wires, which are respectively wound on the fixed frame and the moving frame according to the axial direction, and the moving frame is connected with the driving mechanism. Multi strand soft insulated copper wire is used to replace copper tube winding, which effectively uses the conductor section, saves a lot of copper materials, simplifies the winding process, does not need special winding equipment, saves man hours and reduces costs. Greatly reduce costs and improve economic benefits. High voltage high current high frequency inductance coil The utility model relates to an inductive coil, in particular to a high voltage high current high frequency inductive coil, which comprises a skeleton and a coil wound on the skeleton, wherein the skeleton is mainly a regular polygon disk-shaped skeleton composed of a central plate, a plurality of spoke plates radially fixed on the central plate and a connecting plate connecting the other end of the spoke plate, A row of winding columns are arranged on the spoke plate to form a plurality of concentric regular polygon vertices; The coil is a multi circle concentric regular multilateral disk-shaped coil formed by a plurality of multi strand excitation wires wound in parallel and sequentially around the winding column at the vertex of the concentric regular polygon on the spoke plate. The disk-shaped spiral structure is adopted, with small volume, which greatly reduces the occupied area of the machine room; Multiple excitation wires are wound to reduce copper consumption and reduce high-frequency loss.
