Status identification device of breaker driving mechanism

Abstract

The invention relates to a status identification device of a breaker driving mechanism, which comprises a housing and a panel fixedly connected to the housing, wherein a main shaft connected with a transmission mechanism is arranged in the housing; one end of the main shaft is provided with a status identification disk; the panel is provided with a display window corresponding to the status identification disk; the other end of the main shaft is provided with a cam wheel provided with a roller wheel; the roller wheel is sheaved in a slider component slidingly matched on a linear guide in the housing; the status identification disk is provided with three kinds of status identification; and an electric signal collecting device matched with the cam wheel is arranged in the housing, and is connected with an electric display device arranged on the panel through a circuit. The invention can accurately identify the real time working status of the driving mechanism, and the switching on, the switching off and the releasing of the breaker. Users can conveniently analyse a circuit. The invention has the advantages of simple structure, reliable performance and small occupation space.

Description

technical field [0001] The invention relates to a driving mechanism of a circuit breaker, in particular to a state identification device of the driving mechanism of the circuit breaker. Background technique [0002] With the continuous development of the circuit breaker industry, molded case circuit breakers have gradually become the mainstream of current development. Molded case circuit breakers are often equipped with a driving mechanism to perform closing and opening actions. How to design identification components in a limited space to simultaneously convey the status of the driving mechanism and the circuit breaker while the design is developing in the direction of miniaturization and intelligence is very necessary. [0003] There are two types of state identification devices for the existing circuit breaker drive mechanism: one is a mechanical identification device, which includes a main shaft connected to the transmission mechanism, one end of the main shaft is provi...

AI Technical Summary

Problems solved by technology

The disadvantage of the mechanical identification device is that it is only suitable for short-distance display, and the status identification panel only identifies the closing and opening states of the circuit breaker, but when the circuit breaker switches from the closing state to the tripping state, the identification panel cannot be synchronized The information is fed back to the operator, which will affect the judgment result when analyzing the cause of the circuit; the other is an electronic identification device, which is suitable for long-distance display, and the status of the circuit breaker is marked by indicator lights of different colors

But when a circuit fault occurs, the status of the circuit breaker cannot be displayed

The above two identification devices cannot count the number of times the circuit breaker is used, which is not conducive to the user's timely understanding of the use and service life of the circuit breaker, thus affecting the repair and maintenance of the circuit breaker and the driving mechanism
