Description
Technical field
The invention belongs to low tension switch technical fields, are exactly specifically to be related to a kind of reliable conversion side of switch auxiliary contact
Formula ensure that the reliability of handoff procedure.
Background technology
Low tension switch usually requires electric accessories of the configuration auxiliary contact as switch, and " the dividing " of switch, " conjunction " state can
By the action of the normally-open normally-close transition response switch operating mechanism of auxiliary contact, to pass through electric signal instruction switch
" dividing ", " conjunction " state.
In traditional auxiliary contact handoff procedure, pass through the actuator on hard lever one end and switch operating mechanism more
Contact, the other end are contacted with the microswitch on auxiliary contact, to the division state of search switch, usually, in switch point
In place in a flash, the microswitch on auxiliary contact is converted to normally-closed contact to lock from normally opened contact, but traditional switch exists
There is the case where moving contact rebound when separating brake, causes microswitch to be converted to normally-closed contact from normally opened contact, then touched from normally closed
Point is converted to normally opened contact, cyclic switching, and until rebound stops, such words passes through the division shape of auxiliary contact acquisition switch
State signal occurs as soon as frequent switching, extremely inaccurate to the signal of client feedback, the electric appliance malfunction that is likely to result on circuit and
Larger loss.
The reason of causing above-mentioned phenomenon to occur, is switched during separating brake, and operating mechanism cantilever drive part driving auxiliary is touched
Hard lever, the microswitch on hard lever driving contact contact, make its it is normally opened with it is normally closed between switch.Due to operating mechanism
Drive moving contact together separating brake when, moving contact movement have certain initial velocity and quality, when separating brake encounters limit shaft in place,
Moving contact moves a distance by reaction force pull operation mechanism cantilever, then toward combined floodgate direction, is just struck against in place in separating brake
When limit shaft, contact is switched to normally-closed contact by normally opened contact, but encounters when moving a distance toward combined floodgate direction after limit shaft,
Contact is switched to normally opened contact by normally-closed contact, causes contact switching unreliable.
Chinese patent ZL200810244463.7 discloses a kind of auxiliary switch for circuit breaker, belongs to low-voltage electrical apparatus attachment technique
Field.Including a pair of shell being fitted to each other, the microswitch being located in the shell chamber of shell and the shell chamber for being similarly located at shell
In driving member, the first contact arm of the haptic element for being useful for activating the microswitch and composition are constituted on the driving member spy
For the second contact arm for activate for circuit breaker operation mechanism outside the shell, be characterized in that described in the first contact arm on constitute
It is useful for continuously touching the first, second working face of the haptic element of the microswitch, wherein, the first working face is formed in first and touches
On the upper surface of arm, and the second working face is formed in the auxiliary switch on the top end face of the first contact arm and has protected making for shield microswitch
Use the service life；Reliability of Microprocessor and the safety that microswitch can be improved, finally enable the reliability of auxiliary switch ensure.But
The auxiliary contact is the protection considered when circuit breaker operation mechanism generates overshoot phenomenon to microswitch, on solving
It states since the presence of moving contact rebound phenomena causes microswitch to be converted to normally-closed contact from normally opened contact, then turns from normally-closed contact
Normally opened contact cyclic switching is melted into make the technical barrier of signal inaccuracy.
