The utility model discloses a high tension switchgear circuit breaker baffle, including fixed part, waist and head, the fixed part perpendicular to the waist, the head is located the top of waist, the head for the waist buckles 90, the head with there is the fillet between the waist, the thickness of fixed part and waist all is greater than 5mm. The utility model discloses a thickness of thickening baffle waist and fixed part improves its hardness, makes its difficult aversion warp to bending 90 with the baffle head, making the circuit breaker body block effectively under the ground sword combined floodgate condition that five prevent the tongue, the baffle can not be followed five and is prevented the tongue below and pass through under the ground sword combined floodgate condition, thereby makes the unable operating position that pushed of circuit breaker body, increases security, reliability and stability that the circuit breaker body moved.
