Description

Technical Field

[0001] This utility model relates to the field of circuit breaker structure, and in particular to a circuit breaker dual-indicator structure. Background Technology

[0002] Circuit breaker opening and closing indicators provide an intuitive status display. Operators, inspectors, or inspection robots can easily determine whether the circuit breaker is in the closed or open state by looking at the opening and closing indicators, thereby clearing the circuit's on / off status.

[0003] Secondly, it contributes to safety. Correct opening and closing indicators can prevent operator errors. If the indicators are incorrect, staff may mistakenly believe the circuit breaker is open when it is already closed, leading to incorrect operations that could damage electrical equipment, cause power outages, or even endanger personal safety.

[0004] Furthermore, it facilitates troubleshooting. When a circuit malfunctions, the circuit breaker's open / close indicator is an important clue for troubleshooting. If a short circuit or other fault occurs, checking the circuit breaker's open / close indicator status can help maintenance personnel initially determine whether the circuit breaker is operating normally, thereby narrowing down the scope of troubleshooting.

[0005] Traditional circuit breakers typically only have one indicator. When the indicator malfunctions, it can lead to misjudgment of the equipment. In addition, due to the product layout, a single indicator may be located in an unfavorable position for observation. Therefore, dual indicators are more in line with practical applications. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a dual-indicator structure for circuit breakers, which can solve the problem that general circuit breaker indication structures use a single indicator and are prone to misjudgment.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is: a circuit breaker dual-indicator structure, the innovation of which is: including an indicator nameplate, an indicator clip and an indicator pointer module;

[0008] The indicator nameplate is installed on the outer surface of the circuit breaker. The indicator nameplate has a dual-color indicator area, namely a green indicator area and a red indicator area. The green indicator area represents the circuit breaker being open, and the green indicator area has an O-shaped groove to indicate that the circuit breaker is open. The red indicator area represents the circuit breaker being closed, and the red indicator area has a straight groove to indicate that the circuit breaker is closed.

[0009] The indicator clamp is installed inside the circuit breaker and is fixed to the operating mechanism of the circuit breaker, moving with the operating mechanism;

[0010] The indicator module includes an indicator unit, which has a U-shaped or L-shaped structure. One end of the indicator unit is connected to the indicator clamp, and the other end of the indicator unit extends through the outer casing of the circuit breaker to the outer surface of the indicator nameplate. The operating mechanism of the circuit breaker drives the indicator unit to point to the green or red indicator area of ​​the indicator nameplate.

[0011] Furthermore, the indicator module may include a shift fork, a connecting rod, and a rotating pointer; one end of the shift fork is fixedly connected to the indicator clamp, and the other end of the shift fork is connected to the connecting rod; one end of the connecting rod has a circular hole for the end of the shift fork to pass through, and the other end of the connecting rod is connected to the rotating pointer through a fixed shaft, which is hinged to the circuit breaker; the connecting rod is located inside the circuit breaker, and the rotating pointer is located outside the circuit breaker; the shift fork is driven to move by the operating mechanism, and then the shift fork drives the connecting rod to rotate around the fixed shaft, thereby realizing the rotation of the rotating pointer so that the rotating pointer points to the green or red indicator area of ​​the indicator nameplate.

[0012] The advantages of this utility model are:

[0013] 1) In this utility model, green and red markings are set on the indicator nameplate to indicate the opening and closing of the circuit breaker. At the same time, the indicator nameplate is also set with the circuit breaker opening and closing indicator symbols. In addition, the indicator pointer module indicates the on / off area represented by the indicator nameplate on the circuit breaker, realizing dual indication of the circuit breaker opening and closing. By using different transmission schemes, a dual indication scheme is designed on the circuit breaker, thereby improving the reliability of product operation and facilitating on-site inspection and observation.
