Abstract
Description
Technical Field
[0001] This utility model discloses a status indication structure, belonging to the technical field of molded case circuit breakers, specifically relating to a status indication structure for molded case circuit breakers. Background Technology
[0002] The main function of a molded case circuit breaker is to connect and disconnect the no-load and load current in a high-voltage circuit under normal conditions, and to quickly cut off the fault current when a system fault occurs, so as to prevent the accident from escalating and ensure the safe operation of the system.
[0003] As intelligent molded case circuit breakers become more and more common, the operating handle of traditional molded case circuit breakers has been abandoned or hidden inside the housing as a transmission component, which requires corresponding changes to the indication methods of the three states of the molded case circuit breaker: open, closed, and tripped. Utility Model Content
[0004] Purpose of the utility model: To provide a status indication structure for molded case circuit breakers, solving the problems mentioned above.
[0005] Technical solution: A status indication structure for a molded case circuit breaker, wherein the status indication structure is installed inside the molded case circuit breaker and comprises a bracket, a slider, an indicator, a spring, and several microswitches;
[0006] In a further embodiment, the bracket is fixed to the housing of the molded case circuit breaker, the slider is slidably installed inside the bracket, the indicator is installed on the slider, one end of the spring is fixed to the bracket and the other end is fixed to the slider, and the microswitches are all installed on the bracket and the levers of the microswitches are controlled by the slider.
[0007] In a further embodiment, the bracket is provided with a limiting groove, and the slider slides within the limiting groove of the bracket.
[0008] In a further embodiment, the slider is provided with a baffle, one end of the spring is restricted from moving by the bracket, and the other end is stuck in the limiting groove of the baffle.
[0009] In a further embodiment, the indicator is divided into three colors: red, white, and green. The indicator is attached or printed on the slider. Red corresponds to the closed state of the molded case circuit breaker, white corresponds to the tripped state of the molded case circuit breaker, and green corresponds to the open state of the molded case circuit breaker. The position of the indicator corresponds to the opening on the top cover of the molded case circuit breaker.
[0010] Beneficial effects: This utility model uses three-color indicators to display the working status of the circuit breaker in real time, which facilitates monitoring and fault diagnosis. By observing the status of the indicators, the closing, opening, and tripping status of the circuit breaker can be understood, thereby facilitating the discovery and handling of problems and ensuring the normal operation of the circuit. Red corresponds to the closing status of the molded case circuit breaker, white corresponds to the tripping status of the molded case circuit breaker, and green corresponds to the opening status of the molded case circuit breaker. By observing the status of these indicators, the operating condition of the circuit breaker can be quickly determined, and corresponding measures can be taken in a timely manner.
