The invention discloses a transmission mechanism in a tripper. The transmission mechanism comprises a base, a tripping transmission part, a tripping executing part, a first stopping part, an alarming transmission part, an alarming executing part and a second stopping part, wherein the tripping transmission part can be movably arranged on the base; a tripping triggering part is arranged on the tripping transmission part; the tripping executing part can be movably arranged on the base; a first elastic energy storage component is arranged between the tripping executing part and the base; one end of the first stopping part leans against the tripping transmission part; the other end of the first stopping part leans against the tripping executing part; under the action of the conflicting force of the tripping transmission part, the tripping executing part is driven to compress the first elastic energy storage part to storage energy; the alarming transmission part can be movably arranged on the base; the alarming triggering part is arranged on the alarming transmission part; the alarming executing part can be movably arranged on the base; a second elastic energy storage component is arranged between the alarming executing part and the base; one end of the second stopping part leans against the alarming transmission part; the other end of the second stopping part leans against the alarming executing part; and under the action force of the conflicting force of the alarming transmission part, the alarming executing part is driven to compress the second elastic energy storage component to storage energy.
Description
technical field [0001] The invention relates to a release device in a control and protection switching device, in particular to a transmission mechanism in the release device. Background technique [0002] The control and protection switching device is an electrical device that not only has a switching function, but also can automatically protect against voltage loss, undervoltage, overload and circuit breaker. Protect the power lines and motors, and can automatically cut off the circuit when they have severe overload, short circuit and undervoltage faults. [0003] For example, the existing patent document CN2472341Y discloses an integrated control and protection switching device, which includes a base, a main circuit contact group, an electromagnetic transmission mechanism, an operating mechanism, an isolation mechanism, an overcurrent release, an interlock mechanism, and a power detection relay. The differential mechanism of the overcurrent release has three bimetallic ...
