For the electrical consumers 11 . 12 It is electrical consumers who only need a single-phase supply of electrical energy in the electrical consumers 13 and 14 These are three-phase consumers, ie these electrical consumers are operated in three-phase via a three-phase current. The power supply takes place via lines L, so that the electrical consumers 11 and 12 only one power supply line L, in the three-phase loads 13 and 14 However, three power supply lines L lead to the electrical load. These power supply lines L are taken from a power supply network, which in 1 not shown. Normally, a high-voltage power supply to a switching transformer or to a cabinet, via which then the individual electrical loads are secured via a contactor or a fuse supplied with power. In each of the power supply lines L, which conduct the electric power to the electric consumers, is a sensor unit 15 . 16 arranged. This is arranged in such a way that the sensor unit 15 . 16 has at least one sensor which is integrated in the power supply lines L, or clipped or plugged over this. The sensor unit determines this sensor 15 . 16 , what a 1 in the power supply lines L of the electrical consumers 11 . 12 . 13 and 14 Drawing involved in the electrical consumer 11 . 12 . 13 . 14 supplied current and the applied voltage. This detection takes place exactly at pre-settable time intervals. These time intervals can range from fractions of a second to several hours. In addition, a particular embodiment of the sensor unit is denoted by the reference numeral 16 represented, since this is an embodiment of the sensor unit 16 for three-phase connections. This is a sensor unit 16 executed such that a simultaneous detection of three-phase supplies to a three-phase machine is detected. Here, in turn, a sensor is present, which determines the electrical operating parameters such as voltage and current over the single phase of the three-phase current and this of the sensor unit 16 then provides. Each of the sensor units 15 . 16 has a microcomputer unit 17 on. This is in the sensor unit 15 . 16 integrated. This microcomputer unit 17 serves to separate from the sensors in the sensor units 15 . 16 stored electrical quantities stored in a buffer, which is also in the sensor unit 15 . 16 is arranged, as well as a communication via data lines D with a storage computer 18 to enable.

In an advantageous embodiment of the invention, the buffer is replaced by a removable storage medium. Alternatively, such an exchangeable storage medium is present in addition to the buffer. The removable storage medium is, for example, an SD memory card, a USB memory stick, a micro hard disk. It is in these embodiments an interface, provided in mechanical and electrical form, by means of which the removable storage medium can be connected and / or plugged in, so that a corresponding connection is made so that the data written to the removable storage medium or in / on this can be stored.

Each one of the sensor units 15 . 16 is assigned an identification number, so that the storage computer 18 the A individual data stored, exactly one of the sensor units 15 . 16 can assign.

To the storage computer 18 is an evaluation calculator 19 connected. The evaluation calculator 19 is used for evaluation in the storage computer 18 existing data. The storage computer 18 and the evaluation computer 19 are connectable via a data line, preferably a data bus.

In 2 are electrical consumers 21 shown. This is z. Example, a motor, preferably a three-phase motor or an electric machine, such as an injection molding machine for plastic parts, a soldering line or a lathe, electrical loads, such as lamps or bulbs or electrical equipment, such. As computers, printers, etc.

Every electrical consumer 21 is connected via corresponding power supply cable L1, L2, L3 to the power grid and refers to its energy. To protect the electrical consumers 21 and the power supply lines, the power supply cables L1, L2, L3 are passed through fuse. The fuses are located in fuse boxes and have fuse holders 7 on. Such fuse holders 7 which are present in fuse boxes are in 2 shown schematically. About the fuse holder 7 The fuses or contactors are used to automatically break the power supply if there is a defect or inadmissible currents, ie overload. In or on or above each of the contactors or each of the fuses is a sensor unit 22 integrated. In this sensor unit 22 it is a measuring arrangement according to the invention, by means of which the electrical voltages and electrical currents, which via the power supply lines L1, L2, L3 of the electrical load 21 be supplied. The sensor unit 22 has, for example, a sensor in the form of a Hall sensor, which is slipped over the current-supplying power supply line L1, L2, L3 or clipped over this, so that this sensor both the electrical load 21 voltage applied as well as by the corresponding power supply line L1, L2, L3 of the electrical load 21 Inflowing current are continuously detected. These values, which are determined by the sensor unit 22 are detected by a microcomputer unit 23 with which the sensor unit 22 is stored in a cache. In an advantageous embodiment of the invention, the sensor unit 22 with the microcomputer 23 arranged in a housing together. In this case, then the other functionally necessary elements, such as, for. B. Buffer and display integrated. In order to enable a continuous time evaluation, a clock is available in addition; this is advantageously done by the microcomputer unit 23 displayed. This clock is a software routine in the microcomputer unit 23 implemented, preferably as a registered (embeded) program. This internal clock can be tuned to the second and also has a date function. Thus, from the microcomputer unit 23 Each individual measured value can be assigned an exact time with day, month, year, hour, minute, second. The collected data is stored in the buffer memory under the provision of a corresponding time stamp. In addition to these times and to the values determined, the microcomputer unit calculates 23 the other electrical operating parameters, such as power consumption, phase shift between current and voltage, reactive power, active power, apparent power, RMS voltage, RMS value of electrical current, peak voltage and peak current. These values are also saved precisely in time for the measurement.

The housing in which the microcomputer 23 is arranged, has an interface 24 on. About this interface 24 is this with a storage calculator 25 connected. In the storage computer 25 become the of the sensor units 22 retrieved data from the buffers and stored there. To now an exact assignment of the individual sensor units 22 and the respective electrical consumer 21 To allow, it is provided that each sensor unit 22 an exact name is assigned. This assignment can be made either mechanically by applying to each individual sensor unit 22 a predefinable number is adjustable. Alternatively, this can be done electronically via the arranged microcomputer unit 23 respectively. In that regard, a communication takes place between the storage computer 25 and one to the storage computer 25 connectable evaluation computer 26 , About the evaluation calculator 26 can the connected sensor units 22 be configured. In addition, via the evaluation calculator 25 the internal clock of the sensor units 22 can be set to a predetermined value, as far as can also be via the interface 24 an external time can be specified, so that all on the evaluation computer 26 or at the storage computer 25 connected sensor units 22 run synchronously.

The storage computer 25 continuously calls the data from the latches to the sensor units at predetermined time intervals 22 and stores them. The thus in the storage computer 25 present data on the electronic consumption values and time-accurate performance data, in particular electrical performance data of the electrical consumer 21 can via the evaluation calculator 26 be evaluated. This is in particular dere provided a long-term monitoring. The evaluation calculator 26 represents every single electrical consumer 21 If there are several, with its determined energy data and performance data. It can be done at the individual adjustable times at which the detection of the energy data, thus a graphical representation of the time course of the individual electrical parameters. Thus, based on the change in the electrical parameters, such as the applied voltage, the power consumption, the reactive power and the current intensity to individual parameters of the electrical load 21 getting closed. Thus, for example, it can be recognized whether individual elements, in particular mechanical elements, are working properly, for example if the currents during commissioning of the electrical consumer 21 significantly higher and longer. This would suggest that, for example, the electrical consumer 21 no longer works properly, for example, a bearing defect would be present etc.

Furthermore, by the long-term analysis and in particular the adaptation of the corresponding parameters of the electrical load 21 also an optimization of the electrical consumer 21 to electrical consumption values. In particular, it is essential that the energy data is sent clocked to the storage computer; this takes place at continuously fixed, permanent times. The energy data are stored in the storage computer for life, provided with date and time.

About the interfaces 24 The data can be used at any other time, including online, to the evaluation computer 26 be transmitted. The evaluation calculator 26 stands with the storage computer 25 via an interface, eg. As a USB interface, in conjunction. In the evaluation computer 26 it is in preferential execution to a standard PC or laptop.

On the evaluation computer 26 is an evaluation software installed. the interface 24 is in 2 as a USB interface exemplified. Thus, a USB memory stick can be connected to this interface 28 be connected and the data is stored on this.

In 3 is a concrete embodiment of the method according to the invention for monitoring an injection molding machine for plastic parts shown. The injection molding machine 31 has several electrical components. In the 3 are exemplary heating elements 32-1 to 32-5 shown, which heat and melt the plastic granules, which is supplied to the injection molding machine. Furthermore, a hydraulic pump 34 arranged, this is a supplied with three-phase hydraulic pump 34 , The hydraulic pump 34 is necessary to inject the molten plastic mass into the injection mold under pressure. In the injection molding machine 31 Of course, further electrical components are present, which are ignored in the concrete embodiment.

The heating elements 32-1 to 32-5 are each supplied via a phase, ie single-phase, with electricity / energy. In each phase lead L is a sensor unit 33-1 to 33-5 integrated, which monitors and stores the performance data, ie the energy data, every second or every minute and cycle. Thus, the performance of each heating element 32-1 to 32-5 be monitored. The following are the sensor units 38-1 to 38-3 arranged, which the power supply lines, that is, the three-phase supply lines, which the hydraulic pump 34 be supplied and monitor and select their performance data and write. With reference number 37 the storage computer is called, which contains the data of the sensor units 33-1 to 33-5 continuous in time from the individual sensor units 33-1 . 33-2 . 33-3 . 33-4 . 33-5 and 38-1 . 38-2 . 38-3 retrieves. The storage computer 37 can with an evaluation calculator 36 be connected via a data line. It is also possible to connect the storage computer to the Internet and thus provide the data via the Internet. The evaluation calculator 36 then analyzes the correspondingly provided data.

By the performance data monitoring can be determined in a timely manner now, for example, if the current consumption of the heating element 32-1 increases, for example, decreases the power consumption of the heating element 32-1 continuously over time too. This can be determined via the long-term evaluation. If monitoring would not take place, it would go unnoticed and eventually the machine would fail. Now, through the temporal monitoring of this creeping process of increased power consumption of the heating element 32-1 from the sensor unit 33-1 detected. In that regard, an error in the machine can be detected early.

Another form of monitoring and detection of errors results from the fact that, for example, one of the three-phase currents, that of the hydraulic pump 34 be fed continuously increases. This could be an indication that the hydraulic pump 34 Maintenance would be needed or replaced. Therefore, before a malfunction occurs, it can be predicted in advance on the basis of the long-term monitoring. The increased power consumption could also indicate that that lubrication of the hydraulic pump 34 is insufficient, so far would be an increased internal friction resistance. Again, this would not be noticed during normal operation of an electrical machine, an electrical consumer, without the monitoring of the invention. Only by monitoring in the described form can such errors be detected.

Another essential application of the method is that, for example, the temperatures of the heating elements 33-1 to 33-5 Stepped are controlled in their temperature, so that the temperature of the heating element 33-5 less than the temperature of the heating element 33-1 , In that regard, a temperature staircase can be laid. However, the effects of such activation are not energy-verifiable. However, this can be determined by the method according to the invention, since it is possible to visualize the effects on energy consumption over a long-term view. In that regard, by a clever control of the hydraulic pump 34 For example, the work cycles of the machine could be reduced by one percent, the impact on energy consumption can be directly determined and analyzed. In that regard, it is possible to make an optimization with respect to work performance and productivity of a machine in relation to the electrical energy used and the resulting costs by the inventive method.

Over a Long-term analysis is thus a prognosis over the running time of the machine and about the Maintenance types of the machine possible.

In a further advantageous embodiment of the invention, the Sensors or the sensor of the sensor unit arranged separately from the microcomputer become. The sensors are then connected by lines to the microcomputer connected. It can then from the microcomputer a free choice of Sensors are managed.
