Definitions
- the invention relates to a method for determining mechanical parameters of an electrical switching device exposed to environmental influences, the at least one energy store for providing a switching movement for switching on, at least one switching chamber with switching contacts, a contact force spring to be tensioned by the energy storage when switching on, and a drive device for transmitting a switching movement to the switching chamber.
- the invention is based on the object of designing a method of the type mentioned at the outset such that, on the basis of a simple test to be carried out after the completion of a switching device, a statement can be made as to whether the switching device is suitable for a specific intended use.
- a part of the drive device involved in the entire drive movement is equipped with a measuring sensor for determining the Provide part speed; a selected environmental influence is impressed on the switching device with a certain intensity; the dependence of the speed of the part on time is determined; the measurement is repeated at different values of the intensity of the selected environmental influence.
- the speed of the moving part of the drive device it is not necessary to determine the speed of the moving part of the drive device in a large number of times. Rather, it suffices to relate the speeds measured during a switching operation at at least two successive times during the movement of the part and to repeat this step for all measurements.
- the speed of the part is determined at the point in time in the course of the switching movement of the switching contacts of the switching chamber and the speed of the part becomes ⁇ means in which a latch securing the switch-on position takes effect. In this way, a statement is made as to whether sufficient residual energy is still available towards the end of the switching-on process in order to latch the drive device when the switching contacts of the switching device are properly closed.
- switching devices from ongoing production can now be checked in such a way that the switching devices are subjected to a measurement at a normal value of the selected environmental influence and the values determined for obtaining the permissible range of use of the switching device with reference values from measurements are compared with variable values of the selected environmental influence.
- Figure 1 shows schematically a vacuum circuit breaker as an example of switchgear to be examined.
- FIG. 2 A block diagram is shown in FIG. 2 in order to obtain the procedure for obtaining measured values for the properties of switching devices.
- FIG. 3 illustrates, likewise as a block diagram, the procedure for testing a switching device removed from ongoing production.
- FIG. 4 shows the dependence of the energy of the drive device of a switching device as a function of a particular influence of the environment as a diagram.
- Figure 5 is also a diagram showing the angle of rotation of a control shaft as a function of time.
- FIG. 1 shows a vacuum circuit breaker as an example of a type of switchgear to be examined, as is used in the voltage range from approximately 6 to 36 kV and for rated breaking currents up to approximately 50,000 A.
- FIG. 1 shows a vacuum interrupter 1 with a fixed connecting pin 2, a movable connecting pin 3 and connecting bars 4 connected to connecting pins 2 and 3, and a drive device designated as a whole by 5.
- the drive device 5 contains a closing spring 6 and a switch shaft 7, which absorbs the energy of the closing spring 6 and forwards it to one or more vacuum interrupters 1. Shown in FIG. 1 is the switch-off position of the circuit breaker, in which the switch shaft 7 is blocked by a switch pawl 10.
- Arrows E1, E2, E3 and En indicate any influences in the environment in FIG. 1 which act on the circuit breaker and can influence its mode of operation. Such influences can lead to a situation in the Figure 1 indicated, with the switch shaft 7 cooperating opening pawl 11 can not be effective, so that the closed position of the circuit breaker is not fully reached.
- the circuit breaker according to FIG. 1 is provided with a measuring device 14 which allows the speed of the switch shaft 7 to be recorded.
- the measuring device 14 can comprise an inductive displacement sensor, as is customary in experimental fields of electrical engineering.
- FIG. 2 illustrates that a number of power switches with the symbols S1, S2, S3, S4 and Sn are available.
- the designation Sn indicates that the number of circuit breakers to be examined may be arbitrary, but may not be too small to obtain sufficiently reliable results. This number of circuit breakers is exposed to environmental influences, each of which is activated to different degrees.
- a certain environmental influence El which can be, for example, the air pressure or the temperature, is brought into effect in different intensities II, 12, 13, 14 and In, whereby the Labeling indicates that the overall possible spectrum of intensities is provided with a desired or required fineness.
- the circuit breakers S1 to Sn are now examined by means of measuring devices assigned to them in accordance with the measuring device 14 in FIG.
- FIG. 3 shows a circuit breaker Sp corresponding to FIG. 1 with a measuring device 14 which is set up specifically for detecting the rotational speed of the switch shaft 7 at a time t1 and at a further time t2.
- the time t1 corresponds to the moment of contact of the switching contacts of the vacuum interrupter 1 in the course of the switch-on process and the time t2 corresponds to the engagement of the switch-off pawl 11.
- FIG. 3 shows that the circuit breaker Sp is operationally reliable up to the intensity 14 of the environmental influence El.
- FIG. 4 illustrates the energy balance of a circuit breaker of the type considered above as a function of the temperature as an example of one of the environmental influences that occur.
- the switching energy is plotted against the temperature in the diagram in such a way that low temperatures are marked with "- -" and higher temperatures with "+ +". "-", "0" and "+” are intermediate values.
- a straight line is drawn in the upper part of the diagram as a boundary line for the available energy supply. Furthermore, in the lower part of the diagram is also as
- FIG. 5 shows the angle of rotation of the switch shaft 7 of a circuit breaker according to FIG. 1 as a function of time.
- the curve shown in FIG. 5 crosses a reference line parallel to the time axis and approaches this reference line after one or more overshoots.
- Exceeding the reference line in this case marks the point in time at which the opening pawl 11 engages in FIG. 1. If there were no sufficient residual energy available at this point in time, the latching would not be effective and the circuit breaker would not reach its closing position safely.
- the point in time t 1 is entered in FIG. 5, which characterizes the point in time when the switching contacts of the vacuum interrupter 1 touch when switching on.
- the application of the invention is not to vacuum performance Switch limited, but is possible without a change in principle even in switching devices with switching chambers of another type, for. B. with sulfur hexafluoride or another extinguishing gas.
- the described method is also suitable for examining circuit breakers with drive devices which contain other energy stores instead of springs, e.g. B. Hydraulic or pneumatic based storage.
