Problems solved by technology
[0002] In the prior art, the high-frequency transformer will have the following problems in the production process: 1. The yield rate is too low due to the poor quality of the enameled wire
2. In the production process, the technology is immature, and the insulation distance is small but cannot be found, resulting in the problem of short circuit
3. Due to the broken circuit of the product, the temperature of the wire package rises after the machine is installed, causing potential danger to production
4. The phenomenon of burning wire packs occurs, which increases the production cost and the cost is too high

Embodiment Construction
[0013] The test method of the application pulse detection multi-turn coil of the present invention comprises the following steps:
[0014] (1) Standard samples should be used for testing, and the test results should be stored as standard test results;
[0015] (2) Connect the tested product to the testing machine to get the test result;
[0016] (3), compare the test result with the standard test result, if the function curve of the test result is consistent with the function curve of the standard test result, the product passes the test; if the function curve of the test result is inconsistent with the function curve of the standard test result, then The product failed the test.
[0017] figure 1 is a circuit diagram used in the present invention. figure 1 Among them, Ci is the internal capacitance of the tester, Cc is the capacity of the test line, and Cw is the parallel capacity of the coil. Connect the tested product here. R is the energy dissipation equivalent paralle...

The invention discloses a test method for detecting multi-turn coils by means of pulse. Testing is performed by using a standard sample, and the test result is stored to act as a standard test result; then a tested product is connected on a test machine so that a test result is obtained; and finally the test result is compared with the standard test result. The test method is simple and high in visibility and can be directly applied to inductor production manufacturers. Besides, independent operation of the test method can be performed without additional purchasing of other auxiliary equipment so that product yield rate is effectively enhanced and test cost is saved.
Description
technical field [0001] The invention relates to a method for detecting high-frequency transformers, in particular to a method for detecting multi-turn coils using pulses. Background technique [0002] In the prior art, the high-frequency transformer has the following problems in the production process: 1. The yield rate is too low due to the poor quality of the enameled wire. 2. In the production process, the technology is immature, and the insulation distance is small but cannot be found, resulting in the problem of short circuit. 3. Due to the broken circuit of the product, the temperature of the wire package rises after the machine is put on, causing potential danger to production. 4. The phenomenon of burning the wire bag occurs, which increases the production cost, and the cost is too high. Contents of the invention [0003] In order to solve the problems in the prior art, a method for testing produced products is urgently needed. The invention discloses a targeted ...
