Detection
(1) in the selection and use of inductive coil, the first to think of the coil inspection measurement, and then to judge the quality of the coil and pros and cons. In order to accurately detect the inductance and quality factor Q of the inductance coil, special instruments are generally required, and the testing method is more complex. In practical work, this kind of detection is generally not carried out, only the coil on and off inspection and the size of Q value judgment. You can first use the multimeter resistance to measure the DC resistance of the coil, and then compare it with the original determined or nominal resistance value. If the measured resistance value increases much more than the original determined or nominal resistance value, or even the pointer does not move (resistance tends to infinity X), you can judge the coil break; If the resistance measured is very small, it is difficult to determine whether it is a serious short circuit or a local short circuit. In both cases, you can judge that the coil is broken and cannot be used. If the test resistance is not much different from the original determined or nominal resistance, the coil is judged to be good. In this case, we can judge the quality of the coil according to the following situations, that is, the size of Q value. When the inductance of the coil is the same, the smaller the DC resistance is, the higher the Q value is. The larger the diameter of the wire used, the larger its Q value; If multi-strand winding system is used, the more strands of wire, the higher Q value; The smaller the loss of the material used in the coil skeleton (or core), the higher its Q value. For example, when high silicon steel sheet is used as iron core, its Q value is higher than that when ordinary silicon steel sheet is used as iron core. The smaller the coil distribution capacitance and flux leakage, the higher the Q value. For example, the coil of honeycomb winding method, its Q value is higher than that of flat winding, higher than that of disorderly winding; When the coil has no shielding cover and there are no metal components around the installation position, the Q value is higher, and conversely, the Q value is lower. The closer the shield or metal component is to the coil, the more serious the Q value decreases. The position of the magnetic core should be properly arranged; The antenna coils and oscillating coils should be perpendicular to each other, thus avoiding the effect of coupling.
(2) The appearance of the coil should be checked before installation
Before use, should check whether the structure of the coil is firm, whether the wire turns loose and loose phenomenon, lead contact is not loose, magnetic core rotation is flexible, there is no slip buckle, etc.. These aspects are checked and qualified before installation.
(3) The coil in the use of fine tuning, should consider the method of fine tuning
Some coils in the use of the process, the need to fine-tune, rely on changing the number of coils and very inconvenient, therefore, the selection should take into account the method of fine-tuning. For example, single-layer coil can be used to remove the end of the number of trapped coil method, that is, in advance on one end of the coil around 3 ~4 laps, in fine tuning, moving its position can change the inductance. It has been proved that this adjustment method can achieve fine tuning of ±2%-±3% inductance. The coil used in short-wave and ultra-short-wave circuits is usually set aside as fine tuning, and the inductance can be changed by removing or folding the half coil. Fine tuning of multilayer segmented coils can be achieved by moving the relative distance of one segment, and the number of moving segments should be 20%-30% of the total number of turns. Practice has proved that this fine tuning range can reach 10%-15%. For a coil with a magnetic core, the inductance of the coil can be fine-tuned by adjusting the position of the magnetic core in the coil tube.
(4) The inductance of the original coil should be maintained when using the coil
Inductance coil
Inductance coil
Coil in use, do not change the shape of the coil. Size and distance between coils, otherwise it will affect the original inductance of the coil. In particular, the higher the frequency, the lower the number of coils. Therefore, the high-frequency coil used in TV sets is generally sealed and fixed with high-frequency wax or other dielectric materials. In addition, attention should be paid to the maintenance, do not arbitrarily change or adjust the position of the original coil, so as not to lead to detuning failure.
(5) The installation of adjustable coil should be easy to adjust
The adjustable coil should be installed in an easy to adjust position of the machine in order to adjust the inductance of the coil to achieve the best working condition.
