摘要（英）：

The utility model provides a device for automatically disconnecting an operation power supply under low air pressure of an SF6 circuit breaker. The device is characterized in that the device power supply is respectively connected with the SF6 pressure gauge, the microprocessor and the controlled switch through device wires, the SF6 pressure gauge, the microprocessor and the controlled switch are sequentially connected through signal wires, and the operation loop power supply, the controlled switch and the circuit breaker operation loop are sequentially connected through operation loop wires. The device has the advantages that the SF6 circuit breaker operation power supply is automatically switched off when the SF6 pressure of the SF6 circuit breaker is lower than a locking value, manpoweris saved, the SF6 circuit breaker operation power supply can be switched off in time, and the device is novel in design and practical.
