Investigation on the Interruption Process of Molded Case Circuit Breakers Including the Influence of Blow Open Force
نویسندگان
چکیده
To one double-breaker model, experimental investigation on blow open force was carried out. It demonstrates that the ratio between the emerging blow open force and arc power FB/ui decreases with the arcing time, the contact gap has less effect on FB/ui, and the characteristics of the blow open force are similar when the peak value of the short circuit current is beyond 4 kA. Then, according to the experimental data and conclusions, considering the influence of blow open force, the interruption process of molded case circuit breakers (MCCBs) was investigated. It demonstrates the blow open force has significant influence on interruption process and the proposed method is effective to evaluate new design of MCCBs. key words: blow open force, interruption process, circuit breaker, electrodynamic repulsion force

متن کاملAnalysis of Circuit Breakers Using Artificial Stock Market
In various stock markets, there is a system called “circuit breakers” that interrupts dealing of stocks for a certain period when stock price changes greatly. In this paper, we consider the influence of the circuit breakers on a stock market using an agent-based artificial market simulator called “U-Mart”, by controlling the period of interruption and the criterion to invoke the circuit breaker...
متن کاملInvestigating Characteristics of N2, CO2 and CF3I in Contrast to High Current Arcs in Circuit Breakers to Choose a Suitable Substitute for SF6
Specific and sensitive operation of circuit breakers makes an individual position for them in power networks. Circuit breakers are at the central gravity of variations and execution operations. Therefore, an optimum operation is the main reason to investigate about new gases to be used in MV and HV circuit breakers instead of SF6. The arc process has enormous complexity because of hydrodynamic ...
