中文摘要 | Solenoid-operated valves (SOVs) are widely used components in a variety of industries and systems. Though they are small components, their failure can lead to catastrophic failure of the system in which they are placed. Past studies have revealed the electromagnetic coil insulation to be a weakness, and prior work in the AC motor community on twisted pairs has shown that insulation capacitance measurements can reveal useful diagnostic information. Yet, no studies have tracked the impedance spectrum over an aging/degradation period, no methods are available to identify frequencies in the impedance spectrum to be used, there discussion about how to employ coil impedance to determine a degradation mechanism, nor has there been any quantifications of the mechanical properties due to degradation. This paper develops a method of detection of the aging of insulation in low-voltage electromagnetic coils when subjected to elevated temperature environmental conditions by assessing changes in the impedance spectrum. In this experiment, a solenoid valve was powered and subjected to an operating environment equal to its maximum operating temperature. The valve was periodically removed from the temperature chamber and the impedance spectrum measured. The complex impedance was split into its real and imaginary parts and the Spearman correlation coefficient was used to find regions of interest within the impedance spectrum. The results indicate that resistance and reactance provide information that can assist in condition-based maintenance procedures for electromagnetic coils. Furthermore, mechanical properties of the insulation are investigated and reveal differences in degradation due to environmental conditions. |
