Abstract
The utility model discloses a circuit breaker with an online vacuum degree monitoring function. The circuit breaker comprises a vacuum sensor mounted inside a vacuum arc-extinguishing chamber; and the inside of the vacuum sensor is communicated with the inside of the vacuum arc-extinguishing chamber; a vacuum pressure signal inside the vacuum arc-extinguishing chamber is converted into an ion stream signal by the vacuum sensor through an ion column and the converted ion stream signal is transmitted to a monitoring display device so as to display the vacuum degree status inside the vacuum arc-extinguishing chamber in real time. A monitoring method comprises the following steps: when a power grid is energized, the vacuum sensor starts to work to convert the vacuum pressure signal into the ion stream signal; a high-pressure signal is grounded by the ion column to be converted into a low-pressure safety signal; and the low-pressure safety signal is processed by a control processor to monitor vacuum degree on line and display the pressure of gas in the vacuum arc-extinguishing chamber; and the pressure of gas is compared with a pre-set standard numerical value by the control processor so as to realize the corresponding alarming or trip-out action. The circuit breaker is convenient to use and can be used for saving a great amount of labor and materials, thereby reducing the production cost.
