Arc Motion in Vacuum Circuit Breakers
IEEE Transactions on Plasma Science, 1986Arc motion due to self-magnetic fields is investigated theoretically and experimentally. Using an array of four Hall probes 90° apart around a vacuum breaker, we unambiguously determine arc rotation. It is primarily the radio component of magnetic induction that causes this motion.

Vacuum circuit breakers in cable networks
22nd International Conference and Exhibition on Electricity Distribution (CIRED 2013), 2013The impact of switching over-voltages in a public distribution network on cable ageing and the occurrence of earth fault failure are discussed. It is concluded that 95% of the network remains unaffected by the behaviour of the VCB, and that switching over-voltages in the remaining connected Industrial sites don't propagate into the public network ...

New solution of a vacuum circuit breaker
XXIst International Symposium on Discharges and Electrical Insulation in Vacuum, 2004. Proceedings. ISDEIV., 2004To be able to optimise a vacuum circuit breaker one has to pay attention to: - possible short arcing time to reduce the energy dissipated between contacts; - application of a high speed actuator especially for the highest rated voltages; - concentrate on solution of vacuum chambers and contact design generating axial magnetic field (AMF) and the lowest

The chaos in synthetic circuit experiment for vacuum circuit breaker
24th ISDEIV 2010, 2010The chaos characteristic of vacuum circuit breaker (VCB) under different interruption conditions in synthetic circuit experiment is researched. Using four parameter and two parameter method, comparing the influence of the metal vapor arc model, the variations of voltage and current for different VCBs are obtained.

History of vacuum circuit breakers and recent developments in Japan
IEEE Transactions on Dielectrics and Electrical Insulation, 2005Vacuum circuit breakers (VCBs) have been developed and widely applied in Japan to meet the requirements of increasing energy consumption and also in national security of various areas. As a result, for example, a 168 kV two break porcelain type and a 100 kA one break VCB have already appeared in the Japanese market and they are currently being exported

Development of High Voltage Vacuum Circuit Breakers in China
2006 International Symposium on Discharges and Electrical Insulation in Vacuum, 2006This paper introduces research work on the development of high-voltage (HV) vacuum circuit breakers (VCBs) in China from its starting point in 1989 to 2006. In this period, a 126-kV two-breaks VCB prototype and a 126-kV single-break VCB prototype were developed. A latest 252-kV single-break interrupter prototype is introduced. Five HV VCBs technologies

The ins and outs of vacuum circuit breakers
Electronics and Power, 1975It has been known for some 40 years that one of the most effective ways of interrupting an a.c. circuit is to do so by means of contacts in vacuum. Unlike all other interrupters there is no gas in the arc, only metal vapour which condenses very rapidly as the current falls to zero, giving a most predictable performance and a very fast rise of electric ...

Robust optimisation of the spring actuator in a vacuum circuit breaker
Mathematical Structures in Computer Science, 2014We present a concept of robust optimisation design for the spring actuator in a 10 kV/12.5 kA vacuum circuit breaker. We assume the breaking and closing velocity characteristics, which are derived form the technical data of the interrupter, as the specifications for the problem, and take the lengths of the connecting rods of the actuator and the ...

The role of vacuum in circuit breaker technology
2012 25th International Symposium on Discharges and Electrical Insulation in Vacuum (ISDEIV), 2012Based on first installations of electrical energy systems at the second half of the 19th century, apparatus were needed to close and open electrical circuits under load and short-circuit conditions. Looking back to the origin of the development of these apparatus very different media have been used in order to switch electrical currents with the focus ...
