<p>The present invention provides a gas circuit breaker comprising: a container filled with an arc-suppressing gas; a first contact part arranged in the container and provided with a first arc contact; and a second contact part arranged opposite to the first contact part in the container and provided with a second arc contact. The first contact part comprises: a gas blowing chamber comprising a space for storing the arc-suppressing gas used for performing arc suppression to the arc generated between the first arc contact and the second arc contact; a flow path for the arc-suppressing gas, comprising a first opening and a second opening, wherein the first opening is arranged near the first arc contact, the second opening is connected with the gas blowing chamber; and an a planar member arranged in the space of the gas blowing chamber and configured to shield gas flow of the arc-suppressing gas coming from the flow path and split the space into a first space and a second space, therefore, the gas circuit breaker capable of obtaining a sufficient breaking performance for a current by fully rising a pressure in the gas blowing chamber through heat energy of the arc can be provided.</p> |
