Fig. 1 is structural representation of the present invention.

Embodiment

Embodiment one, composition graphs 1 illustrate this embodiment, the Multifunctional trigger device of deformation based input, it comprises output rod 1, conducting block 2, trigger switch 4, normal working indicating 5, warning circuit 6, breaker circuit 7 and a conductive contact 31, No. two conductive contacts 32, No. three conductive contacts 33 and No. four conductive contacts 34;

Described conducting block 2 is fixed on and exports on excellent 1 body;

Operation principle: the new approaches of trigger equipment of a kind of deformation based input that what the present invention adopted is, utilize the change of displacement that the position of output rod is changed, thus the functional loop making the conductor conducting exported on rod different, thus realize multi-functional supervisory and control.

Be specially: the displacement signal of transmission line current information outputs to described output rod 1, first the described conducting block 2 exported on rod 1 can contact two conductive contacts on described normal work instruction loop 5, trigger described normal work instruction loop 5, this timer can indicate transmission line and drive unit normally to work; When ER effect is large, export excellent 1 displacement and continue to increase, until trigger described alarm circuit 6, this timer can indicate transmission line to power on to flow through large, sends alarm; When transmission line transships, export excellent 1 displacement and reach maximum, trigger described trigger switch 4, and open described circuit breaker loop 7, make circuit breaker carry out protection act.

The difference of the Multifunctional trigger device that the deformation based described in embodiment two, this embodiment and embodiment one inputs is, exports the output rod that rod 1 is insulation.
