Microcontroller device for diagnostics of inter-turn insulation of a motor winding by self-induction EMF

摘要

The invention relates to the field of electrical engineering, in particular to devices for monitoring the quality of insulation, characterized by its breakdown voltage, and can be used in tools for diagnosing the state of interturn insulation of the winding of an induction motor or transformer. Technical result that can be achieved using the proposed useful model, is reduced to expanding its functionality by organizing measurements under the control of a computer. Microcontroller devices diagnosis of interturn winding insulation of the motor by self-induced EMF includes a microcontroller, a voltage divider, a digital to analog converter, controllable switch, the converter USART / USB interfaces, RC-filter controlled current source. In this case, the device is configured to transmit a signal to a computer using a USART / USB interface converter and connecting to the keyboard microcontroller through a group of microcontroller inputs. 1 ill.
