Abstract
This paper introduced the technical criterion
the reasonable disposition to basic structure and the close resistance of circuit breaker for 1 100 kV
50 kA GIS developed by Hyosung in Korea.Based on Maxwell 2D 3D software
the electric field distribution of the interrupter in breaker was analyzed
the calculations of the close resister’s thermal capacity and the validate tests were carried out.It is proved that the capability of the circuit breaker is good
and the thermal capacity of the select close resistance can satisfy the requirement.
