Description
(5) МАГНИТОКОНТАКТНЫЙ ПРЕОБРАЗОВАТЕЛЬ(5) MAGNETIC CONTACT CONVERTER
1one
Изобретение относитс к магнитоизмерительной технике и предназначено дл определени магнитных свойств материалов и изделий и вы влени дефектов в структуре магнитных ве- .. ществ. The invention relates to a magnetic measuring technique and is intended to determine the magnetic properties of materials and products and to detect defects in the structure of magnetic substances.
Известен магнитоконтактный датчик дл определени магнитных свойств-, материалов, который имеет разделенную систему намагничивани и измерени 1 J.A magnetocontact sensor is known for detecting magnetic properties, materials, which has a divided magnetization system and measurements of 1 J.
Недостатками известного устройства вл ютс невозможность глу1 окого промагничивани материалов из-за применени переменного тока в намагничивающих обмотках, что приводит к по влению эффекта вихревых токов, и невысока точность контрол материалов.The disadvantages of the known device are the impossibility of the deep magnetization of materials due to the use of alternating current in the magnetizing windings, which leads to the effect of eddy currents, and the low accuracy of control of materials.
Известен таюче магнитоконтактный преобразователь, содержаний Ш-образный магнитопровод. На крайних ctepжн х магнитопровода расположены намагничивающие обмотки, по/:,ключенныеKnown also magnetic transducer, the contents of the W-shaped magnetic circuit. At the extreme magnetic cores are magnetized windings, on / :, connected
к источнику переменного тока и создающие в среднем стержне направленные встречно магнитные потоки, а на среднем стержне - измерительные обмотки, причем одна из них имеет зазор дл установки исследуемого образца, в зазоре среднего стержн помещен ротор 2.to the AC source and generating oppositely directed magnetic fluxes on the middle rod, and measuring windings on the middle rod, one of which has a gap for mounting the sample under study, rotor 2 is placed in the gap of the middle rod.
Недостатками устройства вл ютс ограниченна область применени , по10 скольку возможно исследовать только образцы материалов, соизмеримые с .оазмерами самого устройства} невозможно исследовать более глубокие части образц-а из-за применени переменного The drawbacks of the device are limited scope, since it is possible to examine only samples of materials commensurate with the dimensions of the device itself; it is impossible to examine the deeper parts of the sample, but due to the use of variable
15 намагничивающего пол , так как сказываетс эффект вихревых токов и, как следствие, невозможно точно установить наличие локальных дефектов в структуре образцов и достоверно опре20 делить распределение полей в материалах .15 of the magnetizing floor, as the effect of eddy currents affects and, as a result, it is impossible to accurately determine the presence of local defects in the structure of the samples and reliably determine the distribution of fields in the materials.
