Description
Technical field
The utility model relates to tester, is specifically related to the dielectric loss tester.
Background technology
Enameled wire by the bare wire annealing softening after, through repeatedly japanning, cure again and form.Enameled wire complex manufacturing technology, and it is subject to the influence of factors such as raw material quality, technological parameter, production equipment, environment, is the conformance with standard requirement so will produce satisfies the product of customer requirement again and is not easy.After product created, whether its outward appearance, size and performance met the requirement of the technical standard of product and user's technical protocol, must judge by checking.By check, can determine on the one hand whether conformance with standard requirement of product, whether satisfy customer requirement, can reflect the reasonable situation of production technology on the other hand.So quality inspection has the effect of checking on, preventing and differentiate.
At present, the enameled wire dielectric loss tester on the market, test frequency mostly is 1KHZ, so the dielectric loss value that radio-frequency coil is used the high frequency wave envelope curve just can't be tested.
The utility model content
The purpose of this utility model is, a kind of high frequency enameled wire dielectric loss tester is provided, and this measuring instrument carries out the measurement of dielectric loss value to enameled wire under high frequency, and Measuring Time is short, measuring error is little.
The technical matters that the utility model solved can realize by the following technical solutions:
High frequency enameled wire dielectric loss tester, comprise the measurement cabinet, described measurement cabinet communicates to connect a host computer, be provided with measuring system in the described measurement cabinet, described measuring system comprises that one is used to the measuring voltage output unit of enameled wire input measurement voltage, and the full test frequency of described measuring voltage output unit output is greater than 0.1MHz.In order to improve test speed, reduce test error simultaneously, the preferred 1MHz of test frequency of described measuring voltage output unit output.High frequency enameled wire dielectric loss tester adopts high-frequency signal that enameled wire is measured, and measuring process can at room temperature be carried out, and need not heating.And measuring-signal is strong, and the measuring accuracy height reduces measuring error.Because tested value is very faint, so described measuring system comprises that also one is used to collect the bridge diagram of measurement data.
Described host computer comprises a processor system, an accumulator system, a display system, and described measuring system connects described host computer, and described processor system is input to described accumulator system with the measurement data of described measuring system, stores.Accumulator system can be stored multi-group data, the convenient measurement data of retrieving for examination at any time.Also store measurement data contrast program in the described accumulator system, described processor system reads the measurement data and the measurement data contrast program of being stored and handles from described accumulator system, and result is externally shown by display system.For example: include the calculating of averaging of measuring number of times control, measurement data in the measurement data contrast program, so, host computer will contrast the measurement number of times of programmed control measuring system by measurement data, the repeatedly measurement data measured calculating of averaging simultaneously, and information such as measurement number of times, measurement data, mean value externally can be exported.The calculating of averaging here is primarily aimed at the dielectric loss value that measures.Adopting the form of test report with the output format of measurement data is example, the test man after some relevant informations of processor system having been imported the required usefulness of user such as testDate, test No., test man, display system will be with the form of test report information such as working temperature value, dielectric loss mean value during with testDate, test No., test man, test externally show.
Certainly for convenience the display system data presented is carried out written record, high frequency enameled wire dielectric loss tester also comprises a printing device, and described printing device connects described host computer.
Beneficial effect: as seen from the above technical solution, the utility model carries out the measurement of dielectric loss by high-frequency signal to enameled wire, and Measuring Time is short, measuring accuracy is high, and measurement result is convenient retrieves for examination at any time, and can print with the form of test report, easy to operate, save time.

For convenience display system 23 data presented are carried out written record, high frequency enameled wire dielectric loss tester also comprises a printing device 3, and printing device 3 connects host computer 2.
Measuring process:
At first get an enameled wire, be about 15cm, be sandwiched in the anchor clamps of specimen holder, it is clean to wipe examination with soft cloth then, and then coated one section graphite 43 on the outside surface of the outside paint film 42 of copper conductor 41 is about 5cm, dry up with hair dryer at last, make enameled wire to be measured.At this moment graphite 43 is as an electrode, and the copper conductor 41 in the enameled wire has formed a sample electric capacity as another electrode.
Specimen holder is pushed in the test chamber, start host computer 2 and measure.The measuring voltage output unit of measuring system 11 is an enameled wire input measurement voltage, and bridge diagram is constantly collected measurement data, and sends this measurement data to host computer 2.
The processor system 21 of host computer 2 is input to processing memory system 22 with the measurement data of measuring system 11, stores, the convenient measurement data of retrieving for examination at any time.And result externally shown by display system 23.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
