Abstract (en)

Disclosed is a circuit breaker, including a housing 1 and an arc extinguishing chamber 2 arranged in an interior space of the housing 1, wherein a gas outlet passage is formed in a first sidewall 13 of the housing 1, the gas outlet passage is designed to communicate the interior space of the housing with a surrounding environment of the circuit breaker, at least one deionizing component 3, 4 is arranged between the arc extinguishing chamber 2 and the gas outlet passage, and the deionizing component 3, 4 is configured to allow conductive gases to pass therethrough and designed to cool the conductive gases therethrough. By the circuit breaker having the above-described configuration, the conductive gases are kept inside the housing of the circuit breaker and prevented from flying out of the circuit breaker, thus achieving zero flashover function.
