Abstract
Description
Technical Field
[0001] The utility model relates to a coil turns testing device, in particular to a movable horizontal coil turns testing device. Background Art
[0002] As the core component of the transformer to achieve electrical energy conversion, the coil usually includes a primary coil and a secondary coil. The principle of electromagnetic induction is used to achieve voltage and current conversion through different turns ratios of the primary and secondary coils, so there must be precise requirements for the number of turns of the coil. After the coil is wound, the accuracy of its number of turns cannot be determined. Usually, an intermediate test is performed after the coil and the core are assembled. However, if an abnormal number of turns is detected at this time, it needs to be disassembled and reworked, resulting in a waste of manpower and material resources, and a large workload, especially for dry encapsulated coils that cannot be repaired after casting, resulting in losses. Although there are special coil turns testers on the market, they are expensive, and due to the limitations of the basic wire turns of the instrument, the error is large when testing special coils. In addition, the current test equipment is usually a fixed structure and cannot be moved or adjusted according to on-site test conditions, and the versatility is poor.
