Summary: | The utility model relates to a locking system and in particular relates to a high/low-pressure loop locking system for a compressed air station. The utility model aims at providing a control system capable of achieving high/low-pressure loop locking of a pressure fan of the compressed air station. In order to solve the technical problem, according to the technical scheme disclosed by the utility model, the high/low-pressure loop locking system for the compressed air station comprises a high pressure cabinet and a pressure fan, wherein the high pressure cabinet comprises a control power supply; a control loop is arranged in the pressure fan and comprises a single core PC, a low-pressure loop and a tripping loop; the low-pressure loop and the tripping loop are respectively connected with the single core PC; the control power supply is connected with the single core PC; and an alternating current relay is arranged on the control loop and is connected in series with the tripping loop by virtue of a normally closed contact. |
