An Improved Mayr-Type Arc Model Based on Current-Zero Measurements
In this paper it is shown that the Mayr-type arc models can be used to describe the arc behavior before current zero exactly. Based on this analysis the different types of ‘modified’ Mayr arc models can be explained. As a result of the theory, an improved Mayr-type arc model with a constant time parameter and a cooling power which is dependent on the electrical power input is introduced and use...
متن کاملInfluence of arc chamber parameters on passive resonance circuit of HVDC circuit breakers
HVDC circuit breaker with sufficient interruption capability and interruption speed, as a key technology to enable HVDC transmission in meshed multi terminal networks do not yet exist. AC circuit breakers in combination with a passive resonance path are used to build HVDC breakers even though the requirements for AC breaking strongly differ from requirements for DC current interruption. Current...
متن کاملmortality forecasting based on lee-carter model
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
15 صفحه اولA Method for Obtaining the Electric Arc Model Parameters for SF6 Power Circuit Breakers
Abstract: In this work, a new method for calculating the parameters of electric arc model for SF6 power circuit breaker is proposed. The methodology consists in the optimization of a theoretical function with respect to a group of model parameters in order to achieve a better approximation to a set of experimental data. The theoretical function is an asymptotic solution of the equation for the ...
متن کاملOverview of Current Research into Low-Voltage Circuit Breakers
The low-voltage circuit breaker has been used for many years for network and persons protection. The review papers existing on these devices generally deal with electrical aspects or macroscopic information on the arc but few concern the “fine” understanding of arc behaviour from its ignition between the opening contact to the current limitation stage due to its presence in the splitter plates....
