Abstract

In order to ensure the components of HVDC circuit breaker

which has various components and complex potential distribution

have reasonable arrangement and reliable insulation

combining with the Nan’ao project"The development of 160 kV HVDC circuit breaker"

this paper determines the impulse insulation level of gaps in the DC circuit breaker by simulation

and provides the air clearance design reference through the g parameter method

ensures the air clearance inside 160 kV DC circuit breaker reasonable

gives the design method of the air clearance of HVDC circuit breaker

which provides reference for the insulation design and the valuable experience for future production of DC circuit breaker.
