Comparison of properties of the new electro-mechanical model and circumferential model of the inductive-dynamic drive

Modeling of Electrodynamic Phenomena in an Ultra-Rapid Inductive–Dynamic Actuator as Applied to Hybrid Short-Circuit Breakers—A Review Study

“…The above advantages of the IDD resulted in its taking over from other types of drives (e.g., spring ones) in many circuit breakers, especially in the so-called hybrid circuit breakers (Figure 1b) of both DC [20][21][22][23][24][25][26] and AC used in synchronous switchingoff [27][28][29][30][31][32][33]. The interest of the authors in the study of this type of drive is mainly related to their application in the class of circuit breakers considered [30,[32][33][34][35][36][37][38][39][40][41]. The authors' noted works can be divided into those focusing on the study of electromagnetic [35,40], mechanical [34,38], and thermal [41] phenomena of the drive.…”

References [36][37][38] present the development of measurement systems that allow the experimental determination of the basic drive quantities.…”

“…Finally, articles [30,39] describe the results of tests on hybrid switches in which the basic element is the actuator. More detailed descriptions can be found later in the article, where most of the papers [30][31][32][33][34][35][36][37][38][39][40][41] are further referenced. IDD-type drives are able to meet such strict requirements owing to the enormous momentary accelerations achieved, provided that such IDD parameters are selected that do not exceed critical values.…”

“…Currently, the latest measurement system (authors' system) is equipped with such a camera (Figure 4). Significant results (according to the authors) obtained with the use of an ultra-fast camera recording the movement of the entire disc are presented in [40]. Measurement of the basic quantities recorded in the measurement system discussed, i.e., current using a low inductance resistive shunt and displacement via an optical sensor, can be determined as a direct measurement.…”

“…At this stage of research, the generation of such forces was ruled out. The authors observed the problem of the appearance of such forces during the movement as a result of later research using the new mechanical model described in [40].
