AI Technical Summary
Existing gas-insulated circuit breakers face challenges in providing simple mechanical connections while maximizing interrupting capabilities due to the interference of electric fields with interrupter connections, limiting the dimension and space between interrupters.
The interrupters in the three-phase gas-insulated circuit breaker have a non-circular cross-section, such as oval or elliptic, allowing for increased accommodation of insulating gas and improved exhaust performance, with arrangements like linear or triangular configurations to optimize mechanical and electrical connections.
This design enhances the interrupting capability and accommodates more insulating gas, improving the circuit breaker's performance and handling higher voltage ratings.
