Description

Technical Field

[0001] The utility model relates to the technical field of releasers, in particular to a shunt releaser with auxiliary alarm. Background Art

[0002] Shunt release is a common device in electrical systems, mainly used to cut off the circuit when necessary to protect the safety of electrical equipment and systems. Traditional shunt releases usually only have basic opening and closing functions, and in some special application scenarios, such as when remote monitoring or alarm is required, traditional shunt releases are incapable of doing so. Existing auxiliary alarm mechanisms often have problems such as complex structure, inconvenient installation, and poor reliability. In addition, traditional shunt releases also have some shortcomings in terms of operating handles, contact connections, and drive mechanisms. The design of the operating handle is often not user-friendly and inconvenient to use. The contact connection part may be worn or have poor contact due to long-term use. The structure of the drive mechanism may also be inefficient or easily damaged due to unreasonable design. Utility Model Content

[0005] The beneficial effects of the above structure are: by arranging a mounting bracket in the shell and installing the shunt drive mechanism in the mounting cavity, the basic function of the shunt release is realized. At the same time, the auxiliary alarm function is realized by pivotally connecting the alarm contact, the closing auxiliary contact and the opening auxiliary contact, and arranging a micro switch that cooperates with the alarm contact. This integrated design makes the shunt release more comprehensive and meets the needs of various application scenarios. The mounting bracket is provided with an operating handle assembly between the closing auxiliary contact and the opening auxiliary contact and the shunt drive mechanism, so that the operator can conveniently perform opening and closing operations through the operating handle.

The coil support and the coil are directly fixed in the installation cavity through the installation method, which saves space and makes the structure of the whole shunt release more compact. At the same time, this installation method is also convenient for production and assembly, and improves production efficiency. The transmission rod is connected to the boss by bolts and fixed to the coil support, which ensures the stability of the transmission process. The matching connection between the waist-shaped groove and the positioning column not only ensures the flexible movement of the transmission rod, but also limits its range of movement, avoiding equipment damage or failure caused by excessive movement.

The operating handle assembly is pivotally connected between the outer shell and the cover through the connecting shaft, so that the operating handle assembly is fixed more firmly in the housing, and the housing adopts a split design of the outer shell and the cover, so that the structure of the entire housing is more modular.

[0008] The utility model is further configured such that the operating handle assembly includes a pivot seat connected to the connecting shaft, an operating handle is installed on one side of the pivot seat, a tension spring is arranged between the pivot seat and the operating handle, one end of the tension spring is connected to the pivot seat, and the other end is connected to the operating handle, and the housing is provided with an adaptable notch corresponding to the operating handle, and the operating handle extends out of the housing through the notch. The operating handle extends out of the housing through the notch, so that the operator can directly contact the operating handle to perform the opening and closing operations, making the operation more convenient, and a tension spring is arranged between the pivot seat and the operating handle, and the elastic force of the tension spring enables the operating handle to automatically reset to the initial position after the operation is completed. This automatic reset design not only ensures the normal operation of the equipment, but also avoids the safety hazards caused by the failure of the operating handle to reset.

[0009] The utility model is further configured that the housing is provided with an extension slot corresponding to the micro switch, and the micro switch extends out of the housing through the extension slot. By extending the micro switch out of the housing, it is easier to be triggered by an external mechanical force or signal. In the scenario where an external signal is required to trigger an alarm or other functions, this design can realize signal transmission and detection more directly and efficiently.
