Definitions
- the invention relates to a method for
- Such a method and such a device are known, inter alia, from signal and wire (91) 3/99, page 34.
- Switch failures can cause time-consuming and costly operational disabilities. Such disabilities can largely be avoided today thanks to modern technology.
- Turnout diagnosis systems can often identify superstructure and safety-related faults in the area of a turnout as early as in the development phase; Preventive turnout diagnosis opens up the possibility to counteract the failure of a turnout in a targeted and metered manner through time-optimized maintenance.
- Preventive turnout diagnosis opens up the possibility to counteract the failure of a turnout in a targeted and metered manner through time-optimized maintenance.
- the turnout diagnostic device known from signal and wire consists of voltage transformers and through-current transformers, which tap the voltages and the currents when a turnout rotates on the feed lines of the drive motor. From these variables, a mini computer calculates the time profile of the active power consumed by the point drive motor. The active power increases linearly with the engine torque or the actuating force. The diagnostic system evaluates Information characteristics of the active power curve and their
- Diagnostic information is given by: the power during the unlocking stroke, the power during the tongue movement (positioning force), the power during the locking stroke, the voltage profiles and
- the turnout diagnosis system provides information about: the state of the turnout (residual tongue tension, stiffness of moving parts, jamming due to wear),
- Point machines are monitored in their end positions from the signal box '. There are over the feed lines, " ' the
- the object of the present invention is to provide a method for turnout diagnosis which can also be used in turnout drives which are monitored by extremely low monitoring currents. It is also an object of the invention to provide a corresponding switch diagnosis device.
- the turnout diagnostic device are separated on the input side from the feed lines of the drive, at least insofar as they are feed lines that lead to a current load on the monitoring circuit. This reduces the current consumption of the diagnostic device to the value zero within the times in which it is not effective anyway, so that the monitoring current is no longer influenced.
- the diagnostic device is preferably decoupled from the feed lines of a point machine by switches in the feed lines from the feed lines to the inputs of a detection or evaluation device that detect the supply voltages. Come as a switch especially relay contacts in question. The control of this
- Diagnostic device determines the current active power of the from the then recorded current and voltage values
- the diagnostic devices can be accommodated in the interlocking and preferably assigned to the actuating and monitoring devices of the individual drives. 'i-n- these be integrated. However, it is also possible to route the current and voltage values required for turnout diagnosis on site in the vicinity of the individual turnout drives to decentrally arranged modules, to preprocess the data obtained there, if necessary, and then to evaluate them in a diagnostic facility common to several turnout drives ,
- the data transmission to this common diagnostic device can be wired via copper lines or optical fibers or wirelessly by radio.
- the drawing shows the drive motor M of a switch drive, not shown, which is supplied with energy from the actuator ST of a distant signal box for circulation.
- the supply energy comes from a three-phase network and is fed to the drive via feed lines Ll, L2, L3 and N.
- the control switching means required for switching the motor M on and off are not shown in the drawing.
- the end positions of the drive motor are monitored by at least one monitoring circuit, which is connected to the drive, the motor windings and in the
- a point diagnosis device assigned to the relevant drive. This essentially consists of an evaluation device B from which the rank to the supply lines of the actuator can be tapped off electricity and • voltage values e ' ⁇ and J "rated either directly or downstream central evaluation means are fed.
- the statements of the monitored respectively on the operating behavior The drive takes place by determining the active power converted in the drive during the start-up and rotation of the drive, the respective determined active power curve being compared with corresponding stored reference values or reference value bands; from this, any deviations in terms of size, direction and tendency can be determined and used for need-based maintenance
- Current transformers SW1 to SW3 are used to receive the currents absorbed by the motor, which are designed as continuous current transformers and encompass the supply lines L1 to L3 cause voltages to the evaluation device which correspond to the feed currents flowing in the respectively monitored line.
- the feed lines are connected to the evaluation device via separate feed lines Z, with the feed lines
- Fuses SI can be inserted.
- feed lines which are only inductively coupled to the feed lines, for detecting feed current-dependent voltages do not burden the switch circuit, in particular not during the monitoring phase in which the feed lines are usually equipped with a
- At least those supply lines between the feed lines and the evaluation device, via which currents can flow into the evaluation device when the drive motor is switched off, are to be interrupted during the idle phase of the drive, that is to say the current consumption of the evaluation device from the feed lines during this time completely interrupted or at least reduced to an uncritical very low value.
- Control information for operating the switches can be obtained from the
- Signal box originate; but they can also be generated by the drive or by the evaluation device, which for this purpose via the
- the interlocking-side monitoring current is not or not significantly falsified by the leakage current of the evaluation device, so that the monitoring result of the interlocking is clearly the same corresponds to the respective state of the monitored point machine.
- the current and voltage values extracted from the supply circuits are preferably evaluated in an evaluation device which is arranged in the interlocking. However, it is also possible to carry out such an assessment on site in the vicinity of the point machines or at any point between the signal box and the point machines.
- the respective current and voltage values or the values of the active power formed therefrom can be temporarily stored on site and read out at predetermined intervals and wired or wirelessly to a common one for several point machines Evaluation device are transmitted, in which the diagnosis for a large number of point machines takes place.
- the drive motor of the point machine to be monitored is as
- the invention is not limited to the monitoring of three-phase drives, but can also be advantageously applied to any other point machine, for example, those that come from a single-phase network or from one
- the means for tapping quantities dependent on the supply current are to be designed, for example, as Hall generators.
