When selecting and using inductive coils, you must first think about the inspection of the coils Measure, and then judge the quality and pros and cons of the coil. To accurately detect the inductance and quality factor of an inductor coil, specialized instruments are generally required, and the test methods are relatively complex. In actual work, this kind of detection is generally not carried out, only the continuity check of the coil and the judgment of the value are carried out. You can first use the resistance setting of a multimeter to measure the DC resistance of the coil, and then compare it with the originally determined resistance value or nominal resistance value. If the measured resistance value is much larger than the originally determined resistance value or nominal resistance value, the pointer may even not move. (The resistance tends to infinity) It can be judged that the coil is broken. If the measured resistance is extremely small, it is difficult to compare whether it is a serious short circuit or a partial short circuit. If these two situations occur, it can be determined that the coil is bad and cannot be used. If the detection resistance is not much different from the originally determined or nominal resistance value, it can be determined that the coil is good. In this case, we can judge the quality of the coil based on the following situations. When the inductance of the coil is the same, the DC resistance is smaller and the value is higher. The diameter of the wire used is larger and the value is larger. If it is wound with multi-strand wire, the number of strands of the wire is more and the value is higher. The coil skeleton (or The smaller the loss of the material used (iron core), the higher its value. For example, when a high-silicon silicon steel sheet is used as the iron core, its value is smaller than when an ordinary silicon steel sheet is used as the iron core. The smaller the coil distributed capacitance and magnetic leakage, the higher the value. For example, the value of a honeycomb winding coil is higher than that of flat winding, and is also higher than that of random winding. The coil has no shielding cover. When there are no metal components around the installation position, the value is higher. On the contrary, the value is lower. The closer the shield or metal component is to the coil, the more serious its value will be reduced. The position of the magnetic core must be appropriately arranged and reasonably arranged. The antenna coil and the oscillating coil should be perpendicular to each other, which avoids the influence of mutual coupling.
