Definitions

  • the invention relates to a circuit arrangement according to the preamble of patent claim 1.
  • the known light blocking signal circuit has a circuit in which the individual light sources transmit Special, individually monitored lamp circuits and separate lamp transformers are supplied with many advantages, but bring no improvement with regard to several other problems which occur in the control and monitoring of light signals over longer positions. Above all, the influence of cable capacity, which makes reliable monitoring difficult and necessitates limiting the distance to 6.5 km and the use of expensive special relays, is not eliminated or reduced. The energy consumption of the signals is also unnecessarily high due to the need to use matching resistors.
  • the invention is based on the object of specifying a circuit arrangement of the type described above which enables the operation of all multi-term light signals commonly used in railway systems in a signal-safe manner and with a high level of operational reliability and at the same time has a lower energy requirement and the least possible outlay on cables and components.
  • all monitoring relays are arranged in secondary circuits of the supply transformer, ie that the supply circuit as well is monitored by a monitoring relay arranged in the signal insert and no longer in the signal box by means of a monitoring relay located in a secondary circuit of a special monitoring transformer.
  • diodes are provided as the subject matter of claim 2, which rectify the control and monitoring currents and thus prevent the flow of a capacitive reactive current when a monitoring circuit or a control circuit is interrupted. Any residual AC currents that occur do not influence the AC-sensitive signal relays or electronic circuits used to evaluate the track current component.
  • An embodiment of the circuit arrangement according to the invention reproduced in claim 3 makes it possible to keep the number of cable wires required low. For example, a three-concept light signal can be operated just as safely with just four cable wires as in today for conventional entry and exit signals, where six cable wires are required.
  • An embodiment of the invention described in claim 4, which provides for the operation of the light signal on the three-phase network with 380 V daily voltage, has particular advantages with regard to the required wire cross section and with regard to energy consumption.
  • Another development of the invention is the subject of claim 5 and enables the monitoring of all stop light sources that are not in operation and, according to claim 6, also other elements of the interlocking system located in the vicinity of the light signal, as far as they are functional, while the stop term (red light) is being displayed Are low impedance.
  • Claims 7 to 10 contain configurations of the circuit arrangement according to the invention which, by skillful multiple use of monitoring relays, keeps the required number of these relays as low as possible.
  • An embodiment of the invention described in claim 11, finally, enables a precise adaptation of the secondary voltages of the feed transformer to the operating voltage of the light sources, even with very different positions.
  • the circuit arrangement according to the invention is shown in an operating state which represents the signal term HpO. It consists of a part ST on the interlocking side and a part SE in the signaling area in the interlocking system, which are connected to each other via four cable wires K1 ... K4.
  • the circuit section in the interlocking outdoor area contains three light sources, in this case signal lamps for red, yellow and green light, each with a main thread rtH, geH, gnH and a secondary thread rtN, geN, gnN and for operation in secondary circuits of a common supply transformer TR can be switched.
  • the primary winding of the supply transformer is fed via two of the four cable cores, K1 and K2, from the signal box.
  • the cable wires are connected in the signal box with two phases R, S, of a three-phase network.
  • the various secondary circuits that form the operating circuits of the signal lamps are switched on by contacts of two control relays S1, S2 housed in the signal insert, the windings of which lie in control circuits which can be switched from the signal box.
  • three monitoring relays To monitor the status and function of the signal lamps, three monitoring relays, the red monitor RÜ, the main thread monitor HFÜ and the travel monitor J are provided in the signal insert, each of which has a series of contacts, some of which switch spare circuits in the event that a main thread breaks and that Corresponding secondary thread must be put into operation, some of which are arranged in monitoring circuits, which trigger an error message in the signal box if such a contact opens due to a fault. All control and monitoring circuits are connected on one side, in the signal application, to one of the phases (R) of the three-phase network connected to the primary winding of the supply transformer.
  • the required control current or monitoring current is taken from this phase and flows via the elements to be controlled or monitored and via one of the cable wires leading to the signal box to the neutral conductor or to the third phase of the three-phase network.
  • contacts changeover contacts SSO1, SSO2, ES11, ES12
  • RHÜ, GNÜ, RNÜ which with their windings are located in the individual monitoring circuits and report every interruption of a monitoring current to the signal box circuit.
  • the red main thread rtH is in operation.
  • the operating current flows - this is emphasized by a stronger pulling out of the connecting lines in the figure - from one of several center taps AM1 ... AM3 of the secondary winding of the feed transformer TR via contacts (break contacts S21 and changeover contact S11) of the control relays S2 and S1 and the winding of the Red monitor RÜ for the common connection of the red main thread and the red auxiliary thread, and from there via the red main thread rtH, the winding of the main thread monitor HFÜ, each one further opener S25, S13 of the control relays S2 and S1 for the secondary winding of the feed transformer TR.
  • the operating voltage can be set by selecting the taps AM1 ... AM3, AE1 ...
  • the taps are appropriately attached so that the secondary voltage in the area of the center taps AM1 ... AM3 from one tap to the next by about 10%, in the area of the taps attached near the secondary coil end, however, only by about 2% changes.
  • one of the phase R of the three-phase network connected via the cable core K1 for signal use runs via a current limiting resistor R1 and a diode D1, an NC contact HFÜ1 des Main thread monitor HFÜ, a changer RÜ1 of the red monitor RÜ, an opener S27 of the control relay S2, and the cable wire K3 to the signal box, there via a changer ES11 of a signal control relay, not shown, the so-called replacement signal controller, a changer of a first signal control relay, not shown, and the winding of one interlocking relay, the red main thread monitor RHÜ to the neutral conductor of the three-phase network.
  • the other monitoring circuit also begins at phase R of the three-phase network, which is connected via the cable core K1 for signal use. It is also passed through a current limiting resistor R2 and a diode D2, but runs through a further resistor R3 for free connection of the red auxiliary thread rtN. From there, the monitoring current flows through all the filaments of the signal insert that are in and out of operation and the cable wire K4 to the signal box. Even the magnetic coil of an indusimagnet M can, as shown here, be included in the monitoring circuit.
  • the monitoring circuit - highlighted again in the figure by somewhat stronger solid connecting lines - runs in detail from the connection of the red secondary thread via red secondary thread rtN, red main thread rtH, yellow main thread geH, yellow secondary thread geN, two resistors R4, R5, green secondary thread gnN, green main thread gnH, indusimagnet M, one Changeover switch J1 of the travel monitor J an opener RÜ2 of the red monitor RÜ, all filaments of the replacement signal light sources ErS assigned to the light signal, an adjustable resistor R6 and an opener S17 of the control relay S1 to the cable core K4.
  • the monitoring current flows via a changeover contact ES12 of the substitute signal converter ES1, a changeover contact SS02 of the first signal setting relay and the winding of the signaling device-side signaling relay RNÜ, the so-called red auxiliary thread monitor, to the neutral conductor of the three-phase network.
  • the current in the monitoring circuit is limited to a few milliamperes, so that although the high-resistance winding of the red secondary thread monitor RNÜ responds to the monitoring current, the function of filaments and indusimagnets is not impaired.
  • the operating circuit for the red auxiliary thread rtN runs from a center tap AM1 ... 3 of the secondary winding of the feed transformer TR via the break contact S21 of the control relay S2, the changeover contact S11 of the control relay S1, the winding of the red monitor RÜ, the red auxiliary thread rtN, the resistor R3 and the Opener HFÜ2 of the main thread monitor HFÜ back to the secondary winding of the feed transformer.
  • the primary circuit of the supply transformer remains unchanged compared to FIG. 1.
  • the second monitoring circuit runs from the phase R connected via the cable core K1 to the primary winding of the supply transformer via the resistor R2, the diode D2 the opener HFÜ2 of the main thread monitor HFÜ to the opener S13 of the control relay S1 and from there further as described above in connection with FIG. 1.
  • the signal is to be set to run (HP1), this is done by actuating the signal control relay SS1.
  • the changeover SS10 in the primary circuit of the supply transformer is thereby changed and phase S of the three-phase network is separated from the cable core K2.
  • the red monitor RÜ falls back and its changeover contact RÜ1 and its make contact RÜ2 interrupt the monitoring circuits shown in FIG.
  • the result of this is that the two signaling relays in the RHÜ and RNÜ signal box fall back and a further signal setting relay, the so-called not shown in the figure Press the neutral signal actuator SS0.
  • main green thread gnH On the secondary side of the feed transformer in the signal insert, an operating circuit is now switched via the main green thread gnH, which has the following course: center tap of the secondary winding of the feed transformer AM1 ... 3, break contact S21 of control relay S2, changeover contact S11 of control relay S1, make contact S12 of control relay S1 , Winding the main thread monitor HFÜ, normally open contact S14 of the control relay S1, green main thread gnH, winding the travel monitor J, normally open contact S15 of the control relay S1, tap AE1 ... 5 of the secondary winding of the supply transformer.
  • the actuation of the travel monitor J causes the connection of a monitoring circuit via the cable core K2. This is done by the changeover contact J2, which is a circuit between phase R and the neutral of the three-phase network closes.
  • the monitoring current flows through the resistor R1, the diode D1, the changer J2 of the trip monitor, the cable core K2, the changer SS20 of the signal control relay SS2, the changer SS10 of the signal control relay SS1, a series resistor R6 and the winding of the signal relay GNÜ, the so-called green monitor to the neutral conductor.
  • the main green thread is switched on if the main green thread fails. This is triggered by an opener HFÜ3 of the main thread monitor HFÜ, which establishes a connection between the secondary green thread and the center tap of the feed transformer via a low-resistance resistor R4.
  • the restricted driving concept (HP2) is to be set, this is done similarly to the setting of the driving concept (HP1), except that the signal setting relay SS2 is actuated instead of the signal setting relay SS1. Due to the position of the contacts SS11 and SS22 of the two signal actuating relays SS1 and SS2, the cable core K3 is now connected to phase T of the three-phase network and the cable core K4 via diode D4 to the neutral conductor of the three-phase network. Thus, instead of control relay S1, control relay S2 picks up because it is now supplied with direct current. By means of its contacts S22, S23 and S24, the control relay S2 effects the connection of a secondary circuit which leads both via the main green thread gnH and over the main yellow thread.
  • a break in one of the main threads gnH, geH also leads to a drop in the main thread monitor HFÜ, whose contact HFÜ3 closes a spare circuit via the green secondary thread gnN, the resistor R4 and the yellow secondary thread geN.
  • the monitoring circuit leading over the cable core K2 remains practically unchanged from the position of the travel term shown in FIG. 3.
  • Figure 5 shows the connection of the light sources of the substitute signal ErS, e.g. in the event of total failure of the light signal.
  • ES11, ES12 of the substitute signal actuator ES1 Via change-over contacts ES11, ES12 of the substitute signal actuator ES1, a circuit from phase S in the signal box via the cable core K3, the opener S27 of the control relay S2, a capacitor C2, the light sources ErS of the substitute signal, an adjustable resistor R6, an opener S17 of the control relay S1 , the cable core K4 and a further signal relay GnÜ1 for phase R of the three-phase network.
  • the operating current for the replacement signal lamps partly flows through a diode D3 connected in parallel with the signal relay GnÜ1, which results in a direct current component for the signal relay.
