Device certain special occasions using when need with overload-alarm non-tripping function, really to there is overload current in protecting circuit
When, alarm signal can be provided, while not allowing circuit breaker trip, keep circuit continued power.
Its principle is：When occurring overload current in circuit, electric current will be transmitted to thermo bimetal by thermal element, heat
Piece, the highly expanded face heated bending deformation of bimetal leaf, bimetal leaf are acted on by double golden adjusting screws to draw bar, and promotion is led
Draw bar overturning, microswitch is pushed by draw bar, so that the normally opened of microswitch is converted into normally closed, is then installed by user
Signal lamp or buzzer send out overload alarm signal.
However the microswitch of the overload-alarm non-tripping mechanism of present breaker is only mounted in the side of left side plate,
And lateral plate structure is complicated.
Utility model content
In order to overcome the shortcomings of that background technology, the utility model provide protected cut-out, mainly solve present open circuit
The microswitch of the overload-alarm non-tripping mechanism of device is only mounted in the side of left side plate and the problem of lateral plate structure complexity.
Technical solution used by the utility model is：
A kind of overload-alarm non-tripping mechanism for breaker, including shell, interior be equipped with of the shell can be along itself axis
The draw bar of line rotation, the draw bar peripheral outer wall are equipped with the baffle for being correspondingly arranged with bimetal leaf, further include structure
It is flat that the installation installed for microswitch is equipped on identical first plate and the second plate, first plate and second plate
Platform, the draw bar peripheral outer wall are additionally provided with swing arm, and the swing arm is opened for touching the fine motion when the draw bar rotates
It closes.
The utility model has the beneficial effects that：The utility model provides a kind of overload-alarm non-tripping machine for breaker
Structure, including identical first plate of structure and the second plate are designed with the installation installed for microswitch on the first plate and the second plate
Platform, worker installs optional arbitrary side plate installation when microswitch, simple in construction, easy to disassemble and assemble.
