Simulation of Internal Arcing in High Voltage Switchgear Based on Fluent

Abstract:

Internal arcing faults in the high voltage switchgear may cause serious damage to the equipment and fatal injury to personnel. To simulation the fault arcs based on appropriate calculation methods can not only shorten the development period of arc resistant switchgear, but also save the development cost. In this paper, based on KYN28-12(Z) switchgear, three-dimensional mathematical model of pressure relief channel of circuit breaker chamber in switchgear is established by using the GAMBIT software, then simulate the process of internal arcing in switchgear by adopting FLUENT software. The influence of the length and depth of pressure relief vent, also the loading position of arc discussed in the simulation.
