“…Most implementations of Thomson coil based FMS [9][10][11][12][13][14][15][16][18][19][20], employ a single pulse circuit, perhaps because of simplicity. Its variations include Circuit 1, 2 and 3 as shown in Fig.…”

Thomson coil actuators (also known as repulsion coil actuators) are well suited for vacuum circuit breakers when fast operation is desired such as for hybrid AC and DC circuit breaker applications. This paper presents investigations on how the actuator drive circuit configurations as well as their discharging pulse patterns affect the magnetic force and therefore the acceleration, as well as the mechanical robustness of these actuators.Comprehensive multi-physics finite-element simulations of the Thomson coil actuated fast mechanical switch are carried out to study the operation transients and how to maximize the actuation speed. Different drive circuits are compared: three single switch circuits are evaluated; the pulse pattern of a typical pulse forming network circuit is studied, concerning both actuation speed and maximum stress; a two stage drive circuit is also investigated. A 630 A, 15 kV / 1 ms prototype employing a vacuum interrupter with 6 mm maximum open gap was developed and tested. The total moving mass accelerated by the actuator is about 1.2 kg. The measured results match well with simulated results in the FEA study.

“…As shown in Figure 3, a high speed switch (HSS) with a trip time less than 1 ms achieved by installing an electromagnetic repulsion mechanism and a spring mechanism was proposed [18]. A CL component was also proposed in [18], consisting of HSS, a CL resistor and a counter pulse circuit. When a fault occurs, the fault current could be enforced to zero by adding a counter pulse current.…”

Circuit breakers (CBs) are the main protection devices for both alternating current (AC) and direct current (DC) power systems, ranging from tens of watts up to megawatts. This paper reviews the current status for solid-state circuit breakers (SSCBs) as well as hybrid circuit breakers (HCBs) with semiconductor power devices. A few novel SSCB and HCB concepts are described in this paper, including advantage and limitation discussions of wide-band-gap (WBG) devices in basic SSCB/HCB configuration by simulation and 360 V/150 A experimental verifications. Novel SSCB/HCB configurations combining ultra-fast switching and high efficiency at normal operation are proposed. Different types of power devices are installed in these circuit breakers to achieve adequate performance. Challenges and future trends of semiconductor power devices in SSCB/HCB with different voltage/power levels and special performance requirements are clarified.

“…Few prototypes were presented in the literature published in late 1990's and 2000's but these were without any design criteria or guidelines were presented [16][17][18][19][20][21]. Recent studies report a comprehensive model in FEM software, but do not give evaluation of design variables, especially on the circuit parameters [22].…”

The paper presents the operation transient analysis and multi-physics complexities in the design of a Thompson coil based ultra-fast mechanical switch for hybrid AC and DC circuit breakers. The electromagnetic, mechanical and thermal behavior of the switch has been analyzed through simulation using a multiphysics finite element software. The design variables have been classified into lumped circuit and geometric parameters; the sensitivity analysis by means of systematic and comprehensive simulations on these parameters helped establish the design guidelines. The switch has been designed with optimization for both the circuit parameters and geometrical dimensions of components targeting 2 mm travel for separation within 1 ms.Index Terms-Finite element method, ultra-fast switch, Thompson coil, operating mechanism, hybrid circuit breaker, DC circuit breaker.978-1-4799-6735-3/15/$31.00 ©2015 IEEE
