The utility model discloses a high-tension switchgear having the gas analysis function, which comprises a cabinet body and a fault detection unit arranged in the cabinet body. The fault detection unit comprises a gas acquisition device communicated with the cabinet body and used for extracting air in the cabinet body as a gas sample, a gas channel connected with the gas acquisition device, a gas sensor arranged in the gas channel and used for detecting the content of a specified element in the gas sample, a judging module used for judging whether the detected content of the specified element in the gas sample exceeds a preset value or not, and a fault category determination module used for determining the category of a fault related to the specified element and occurred in the cabinet body on the premise that the detected content of the specified element in the gas sample exceeds the preset value. Due to the adoption of the high-tension switchgear, when a fault occurs to the high-tension switchgear, the self-checking of the high-tension switchgear is enabled. Meanwhile, the detection is prevented from being influenced by the operation state of the high-tension switchgear and more fault categories can be detected.
