The invention relates to a cubicle gas-insulated switchgear comprising a cabinet body. An arc-extinguish chamber and a disconnecting switch are arranged inside the cabinet body. The arc-extinguish chamber consists of an arc-extinguish chamber static-end outlet base and an arc-extinguish chamber moving-end outlet seat. The disconnecting switch includes a disconnecting switch moving contact base and a disconnecting switch static contact base. At least one of the arc-extinguish chamber static-end outlet base, the arc-extinguish chamber moving-end outlet seat, the disconnecting switch moving contact base, and the disconnecting switch static contact base is provided with a temperature sensor. Therefore, whether a working sate of a circuit breaker is normal and whether a working state of the disconnecting switch is normal can be determined in real time; if a fault occurs at the circuit breaker or the disconnecting switch and thus a temperature rise phenomenon occurs at a connection part, the staff can get the information timely by the temperature sensor, so that frequent occurrence of accidents due to a fault of the circuit breaker or the disconnecting switch in the prior art can be avoided.
