Abstract

In the article, the authors investigated a device for testing the insulation of electrical equipment with increased voltage. Insulation in electrical devices is an essential structural element. The electrical strength of the insulation is determined by its ability to withstand the continuous rated voltage for which the installation is designed. But in some cases, the strength of the insulation may deteriorate due to its moisture or due to defect development. Defects can be air inclusions in a solid or liquid dielectric, which further create conditions for the occurrence of partial discharges. The current test scheme for determining the insulation electrical strength margin is considered. A diagram of the developed installation for testing insulation based on a single design and technological component is presented. The aim of the work is to study the dependence of the voltage gain on the frequency change for a single-section and two-section multifunctional integrated electromagnetic component (MIEK). A hypothesis was put forward that the use of a two-section multifunctional integrated electromagnetic component will significantly increase the voltage gain compared to the use of a single-section single design-technological component. In the process of scientific research of the installation for testing the electrical equipment insulation, methods of mathematical modeling were used. The presented device has smaller weight and size indicators and more effective voltage gain indicators. As a result of mathematical modeling, it is shown that the use of a two-section multifunctional integrated electromagnetic component makes it possible to increase the voltage gain to 90, while when using a single-section component, the voltage gain is 9. The results of the studies confirm the relevance and significance of component integration in order to reduce the weight and dimensions of the known devices.
