Below with reference to shown in Fig. 1,4,6, have to the working principle of the indicating fault auxiliary contact of breaker of the present invention
Body explanation.
When breaker A is in normal "on" position, contact supports 5 to be supported the elastic force of reset spring 8 to act on by contact, touching
Head (15,16) closure, shows the normal "on" position of breaker.
It (overloads when breaker A is in malfunction, is under-voltage), the third poke rod 201 of activation lever 2 is by breaker
The effect of the operating mechanism of A rotates counterclockwise, and the triggering end arms 21 of activation lever 2 is pushed up to the first extension bar 51 and supported with moving contact
5 movements upwards export fault-signal so that normally open contact (15,16) disconnects；Meanwhile the operating mechanism of breaker A pushes failure
Second poke rod 14b of drive rod 14, failure drive rod 14 rotates, so that the failure on the indicating fault end 142 of the other end refers to
Show that face 14a is exposed to the underface of failure watch window 17, shows fault state of circuit breaker.
When the failure of breaker A is short trouble, while the push plate of breaker is moved towards X-direction, and push plate pushes first
Poke rod 13b, short-circuit drive rod 13 are moved along its rotary shaft 13a towards Y-direction, so that indicator gag lever post 113 and ontology limit
The spacing relation of bar 13c releases, and indicator 11 is moved towards Z-direction, and ontology gag lever post 13c is caught in limit in limiting groove 112 and refers to
