Embodiment one
As shown in Fig. 1 to 3, breaker mechanical motion state is changed into electricity by a kind of vacuum circuit breaker signal feedback mechanism
Signal is transferred to train control system, specifically includes cylinder 1 and feedback component；The feedback component includes two sets, is symmetrically set
It is placed in 1 two sides of the bottom of cylinder.
The feedback component includes push plate 2, piston push rod 3, adjusts bolt 4, microswitch group 5, lobe plate 6, left branch
Seat 7 and right support abutment 8；Microswitch group 5 is fixed on the bottom of cylinder 1 by punching bolt by the left support abutment 7 and right support abutment 8
Portion, the fixed form of punching bolt are well known technologies, and which is not described herein again, and it is straight that with right support abutment 8 screw can be used in left support abutment 7
Connect the bottom for being fixed on cylinder 1.
Include piston 10 in the cylinder 1, controlled and moved up and down by compressed air, lobe plate 6 is set to microswitch group 5
Operating surface side, for controlling microswitch；Microswitch group 5 includes 4 microswitches, and microswitch is separately connected letter
Number output line 9, altogether exportable 8 road signal.
The microswitch that this example is selected, a microswitch have a pair of of normally opened contact and a pair of of normally-closed contact, contact both ends
Be connected to breaker connector by signal output line 9, the commutation of normally opened contact and normally-closed contact by its operating parts compression and
Release realizes that the commutation of microswitch itself normally opened contact and normally-closed contact can be realized by compressing and discharge operating parts.
The piston 10 of 3 one end of piston push rod connection cylinder 1, the other end connect push plate 2, specific push plate 2, piston
