“…In equations ( 1)-( 6), driving force (F EM ) and equivalent inductance (L) are key parameters that determine the dynamic characteristics of LEAs, and they are usually expressed as functions of driving current (i) and displacement (s) [18,19]. Usually, analytical expressions can be obtained for equivalent inductance and driving force under certain assumptions based on the equivalent magnetic circuit method [20][21][22][23][24][25][26].…”

Linear electromagnetic actuators (LEAs) are widely used in tokamaks, but they are extremely sensitive to and are prone to fail in high-strength stray magnetic field (SMF) which is usually a concomitant with tokamaks. In this paper, a multi-physics coupling analysis model of LEA including magnetic field, electric circuit and mechanical motion is proposed, and the dynamic characteristics of LEA in SMF are studied in detail based on the proposed model. The failure mechanism of LEA in SMF is revealed, and the influence of SMF on the dynamic performance of LEA is studied and quantified. It is shown that, the failure threshold of the LEA selected in this work under the rated condition is 27 mT and 14 mT in the positive and negative direction, respectively. Under a typical SMF of 10 mT in the negative direction, the closing time of the LEA will be extended 40%, while its opening time will be shortened about 10%. Experimental tests are also conducted, which verify the validity of the proposed model and the analysis results. This paper provides a basis for the diamagnetic optimization design of LEA, and it is of great significance to ensure the reliable operation of tokamak.

“…Therefore, in this manuscript, the switching times of different rated currents of the apparatus contactors are not analyzed. In [15,16], laboratory measurements of low voltage contactor switching times are presented. In relation to the proposed SCB, neither the switching times of contactors analysis nor application of additional electronic controller to switching operation are not required.…”

The subject of the article is a description of the operating principle of the new proposal of the selective circuit breaker, which is an extension of the existing selective devices. The solution proposed in the article allows one to increase the selectivity range of classic selective circuit breakers. In the case of networks with high values of short-circuit loop impedance, operating at reduced supply voltage, the proposed solution will not limit the short-circuit current too excessively as it is in the case of classic solutions. This advantage will allow for the correct reaction of the protections preceding them. The article presents the structure and analysis of the selection of parameters of the proposed solution. The results of simulation calculations have also been illustrated.
