Microcontroller device for diagnostics of inter-turn insulation of an electric motor winding with a megohmmeter function

摘要

The utility model relates to the field of electrical engineering, in particular to devices for diagnosing insulation of an electric motor characterized by its breakdown voltage, and can be used to build diagnostic tools for all types of insulation of an electric motor: inter-turn, inter-winding, between a winding and a housing, as well as measuring insulation resistance. Effect: expanding functionality by measuring using computing resources of a computer. SUBSTANCE: device contains a microcontroller, a voltage divider, a digital-to-analog converter, a first controlled key, an indicator, a constant voltage source, a second key, an exemplary inductance, a USART / USB interface converter. Moreover, the USART module of the microcontroller is connected to the USART / USB interface converter, configured to connect to the USB interface of the computer. 1 ill.
