  • Dead tank circuit breaker with surge arrester connected across the bushing tops of each pole
    Patent number: 9728362
    Abstract: Surge arrester structure is provided for a dead tank circuit breaker. The circuit breaker has a pole assembly with a first electrical terminal in a first bushing, and a second electrical terminal in a second bushing. The first terminal is electrically connected to a stationary contact and the second terminal is electrically connected to a movable contact. The surge arrester structure includes a surge arrester having first and second opposing ends. A first conductor structure electrically and mechanically connects the first end of the surge arrester with an end of the first terminal. A second conductor structure electrically and mechanically connects the second end of the surge arrester with an end of the second terminal. The surge arrester is electrically connected parallel with respect to the stationary and movable contacts so that the surge arrester can limit transient over voltages occurring across the contacts when the contacts are open.
