| Abstract: | Based on the first law of thermodynamics and the law of hydrokinetics, the mathematic model of the pressure characteristic was established for the 252 kV self-extinguishing SF6 circuit breaker, and the pressure characteristic curve of the arc-extinguishing chamber can be obtained through computation. The pressure characteristic can be achieved by the test. The comparison of testing with the computation indicates the accuracy of theoretical calculation result. |
