ESTIMATING THE THERMAL PERFORMANCE IN IMPULSE CAPACITORS AT MEASURING THE COIL COOLING PARAMETERS

Abstract

A comprehensive study of thermal processes and methods for increasing the thermal stability of pulsed power capacitors of the serpentine type widely used in induction units and power electronics is carried out. One of the key problems in the operation of such devices is overheating, which significantly reduces their service life, reliability and stability of operation. In this regard, special attention is paid to the development of effective cooling systems that ensure timely and uniform heat removal from active elements.

The main objective of the study was to determine the optimal parameters of water cooling, including the flow rate of the cooling liquid, which made it possible to significantly reduce the temperature of power capacitors under their intense pulse load. The experimental analysis of the thermal mode showed that an increase in the fluid circulation rate improves heat exchange and helps to reduce overheating, which is confirmed by a series of measurements and a graphical presentation of the results.

The paper also considers the basic principles of heat transfer, heat balance and heat transfer mechanisms in the cooling system, as well as the effect of parameter optimization on the heat transfer coefficient. The proposed measures allowed to significantly increase the energy efficiency of the installation, increase the service life of capacitors and improve the overall reliability of power circuits.

The importance of a comprehensive and systematic approach to heat removal in pulse power systems is emphasized. The presented results create a basis for further research and development of modern technological solutions in the field of cooling power components, which is relevant for a wide range of industrial applications related to induction technologies and high-intensity pulse loads.
