The utility model has substantive distinguishing features and progress with respect to prior art, and specifically, this novel control module has following advantage:
1, the control module volume is less than 1/10th of the gravity safety type relay, thereby for having saved a large amount of device spaces in the railway machinery chamber;
2, owing to adopted the electronic switch that does not have mechanical contact to realize breaking current, thereby the signal make and break process can not produce spark;
3, to exceed 2 orders of magnitude of mechanical switch that the contact is arranged the serviceable life of electronic switch, adopt special small-sized safety relay that electronic switch is carried out the overvoltage protection of port in addition, thereby prolonged the serviceable life of equipment greatly;
4, use contactless electronic switch to carry out logic control, use has the special small-sized safety relay of contact to protect control, two kinds of switches of different nature complement one another, only use the form of switch with mechanical contact than existing equipment, action and State Control for railway signals equipment have significantly improved its safety, reliability;
5, because employed special miniaturization safety relay, its security is guaranteed by the phenomenon that " elastic force " this nature never disappears, and it is not subjected to the influence of putting position, thereby this control module both can also can be directly installed on the other use of railway signals equipment rail in the indoor use of railway machinery;
6, this control module dailyly need not maintenance, safeguards, cooperates peripheral intelligent control signal, can realize localization of fault and eliminating fast, and equipment failure is dropped to minimum to the influence of rail transportation efficiency.
Description of drawings
Fig. 1 is circuit theory diagrams of the present utility model;
Fig. 2 is an application synoptic diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
As depicted in figs. 1 and 2, a kind of novel control module of railway signals equipment, it comprises an electronic switch K1 and a safety relay J1, wherein, the end of the normally opened contact J1-1 of described safety relay J1 links to each other with the A of described electronic switch K1 end, the K end of described electronic switch K1 links to each other with the end of the normally opened contact J1-2 of described safety relay J1, the other end of the normally opened contact J1-1 of described safety relay J1 is the signal input part of this control module, the other end of the normally opened contact J1-2 of described safety relay J1 is the signal output part of this control module, and the G end of described electronic switch K1 and the line bag S of described safety relay J1 are respectively the electronic switch signal control end and the relay signal control end of this control module.
Described electronic switch K1 is a gate electrode capable of switching off type thyristor, and this thyristor is operated in the on off state that ends with saturation conduction, its on-state average current I
T (AV)Should be at 7.5A～10A, the repetitive peak off state voltage U of electronic switch K1
DRMWith repetitive peak reverse voltage U
RRMShould be greater than 1000V.
Described safety relay J1 comprises two groups of above normally opened contacts at least, and safety relay J1 should be suitable for welding use on the circuit board.
After applying control signal on the line bag S of described safety relay J1, normally opened contact J1-1 and normally opened contact J1-2 closure, after the control signal that applies on the line bag S disappears, normally opened contact J1-1 and normally opened contact J1-2 rely on elastic force to disconnect, and the normally opened contact J1-1 of safety relay J1 and the direct current breaking capacity of normally opened contact J1-2 should be greater than 8A.
The logic control whether described electronic switch K1 realization is communicated with the signal input and output, described safety relay J1 realizes the protection to described electronic switch K1, guarantees module self and controlled signal device security, and direct breaking current.
Special small-sized safety relay comprises wired bag S, two groups of normally opened contact J1-1 and normally opened contact J1-2, is electric insulation between control signal on the line bag S and the normally opened contact; When on this relay line bag S, not applying control signal, this special small-sized safety relay normally opened contact J1-1 and normally opened contact J1-2 is in off-state, when applying control signal on the line bag S at safety relay J1, because going up, line bag S produces electromagnetic attraction, make and the mechanical linkage action drive normally opened contact J1-1 and normally opened contact J1-2 closure.
As depicted in figs. 1 and 2, this Figure illustrates the utility model making a practical application of a principle in railway switch goat control circuit; The principle of work of railway switch is: the rotation of track switch has two positions, location and antiposition, the change of position can make train continue to advance to the another one track from an orbital transfer, point machine is actual to be a motor coil, powers up to motor coil, and goat is action just, switch with follow up movement has been realized from an evolution to the another one position simultaneously, when coil did not power up, goat was failure to actuate, and track switch remains on current location and maintains static.
This control module is exactly to realize the control that whether powers up for point machine, and concrete use-pattern is: the signal input part of control module inserts the positive control power supply KZ of point machine; The signal output part of control module is connected with one of point machine coil; The other end of point machine coil is connected KF with the negative control power supply; The control signal of the signal controlling termination outside of control module.
Based on foregoing description, when sending electricity for the point machine coil, the control signal of control module outside needs to send control signal for earlier the line bag S of safety relay J1, make safety relay J1 pick up, and then normally opened contact J1-1, normally opened contact J1-2 junction closure, the control signal of control module outside sends control signal for the G end of electronic switch K1 then, make electronic switch K1 saturation conduction, be that equivalent resistance is near 0 ohm between the A end of electronic switch K1 and the K end, and then the positive control power supply KZ of point machine has delivered on the point machine coil.
Based on foregoing description; when needs disconnect the power supply of point machine coil; the control signal of control module outside needs to disconnect earlier the G end control signal of electronic switch K1; make electronic switch K1 end; this moment, the point machine coil power was cut off; then; in order to realize of the protection of special small-sized safety relay for electronic switch K1; the control signal of control module outside need disconnect the control signal on the safety relay J1 line bag S, makes normally opened contact J1-1 and normally opened contact J1-2 contact disconnect.
Like this; just realized using that this control module is safe and reliable has controlled a railway signals equipment; be the operating state of point machine, and, prolonged the serviceable life of this control module greatly by of the protection of special small-sized safety relay for electronic switch K1.
