Calculation of Temperature Rise for High-Voltage Induction Motor with Compact Type in Starting Process

Abstract:

Medium-sized high-voltage motor’s starter temperature rising is difficult to accurately calculate. In this paper, the heating and cooling process at the start of the motor windings are analyzed, from the perspective of practical engineering, according to the actual structure of the motor, the motor drag establish a network model and dynamic thermal network diagrams, calculating the electrical heating and cooling conditions. This paper took consideration of the influence to the motor heating from current and impedance changes in the process of starting. Taking the times as the step size and basing on the raw heat and heat capacity of each period to calculate the motor temperature rise of the motor windings. For example the motor of YJKK500-4, 2500kW motor, calculating the motor winding temperature raise, the calculation which achieved with the experimental results, the calculation method has the engineering practicality.
