Definitions
- the invention relates to a monitoring method for a fluid enclosed in a container, in particular an electrically insulating fluid.
- a monitoring method can be found in patent DE 103 02 857 B3, for example. There it is proposed that the amount of insulating gas supplied or withdrawn from a container be recorded and balanced. Although this is a simple way of recording the filled and withdrawn insulating gas, the information is available relatively late. It is not possible with the known method to obtain information about tendencies that would allow possible action in advance.
- the object of the invention is therefore to provide a monitoring method which enables the condition of a fluid to be assessed earlier.
- the object is achieved in a method of the type mentioned at the outset in that first data, which map an amount of fluid present in a container, with second data, which one has introduced into the container
- map te / withdrawn fluid quantity be compared and a discrepancy between first data and second data is determined.
- Fluids are, for example, liquids or gases that can be used to electrically isolate a phase conductor.
- electrically insulating fluids in particular are used. If necessary, these fluids can also be used within the container under pressure can be set.
- the container in this case is called a pressure vessel.
- the insulation strength of the electrically isolating fluid can be further increased.
- volatilization of the same is additionally promoted due to an existing differential pressure. But even when using fluids free of differential pressure there is a risk of the fluid evaporating from the container.
- the fluid can, for example, wash around a phase conductor and thus effect electrical insulation of the same.
- a section between the phase conductor and the container or other phase conductors acts as an electrically insulating end due to the presence of an electrically insulating fluid.
- Sufficient insulation strength is necessary, in particular when pressure fluid insulation is present, since in this case the distances to produce sufficient electrical insulation can generally be reduced with increasing pressure.
- fluid losses lead to limitations in the insulation strength comparatively quickly.
- joints which must be sealed using appropriate Dichtun conditions to prevent a fluid from escaping, are subject to aging in the course of an operation, so that there is an undesirable leakage of fluid from the interior of the container z. B. can come into the environment. These losses are undesirable and should be diagnosed as early as possible.
- the first data were collected that depict the amount of fluid present in a container.
- An image of the amount of fluid present can preferably take place by measuring the density of the fluid enclosed in the container. The density is a suitable measure to represent the dielectric strength. About the volume given by the container and the density of what is in the volume Fluids, the amount of fluid can be determined. The amount of fluid can be specified, for example, in the form of a mass.
- the first data can thus directly or indirectly map the mass of the fluid enclosed in the container.
- the density of the fluid can increase with the incorporation of other substances into the fluid, for example by incorporating foreign gases or foreign liquids. Leakage of the fluid enclosed in the interior of the container generally leads to a reduction in density. Furthermore, the density can also be influenced by adding more fluid. For example, a loss of fluid by refilling can be compensated for. There is preferably the possibility of continuously recording the amount / mass of the fluid enclosed in the interior of the container and to map this information in the form of first data.
- the amount of fluid added or removed can be balanced.
- a measurement can be determined, for example, via flow measuring devices which are arranged, for example, in the course of filling lines, in particular on filling nozzles.
- the fluid quantities can be netted.
- a flow device can use a volumetric measurement method, for example. This should preferably be done with temperature compensation.
- the quantities supplied or removed can also be determined by weighing.
- the present first data and the present second data can, for example, be merged in a computer cloud (distributed computer system) and be subject to processing there.
- the Processing a discrepancy between the first data and the second data can be determined.
- the first data and the second data should contain the same information with regard to the fluid quantities if the container is sufficiently leakproof.
- a difference between the first and second data can be determined, which is an image, for example, of the loss of fluid from the container.
- the occurrence of an excess of fluid inside the container indicates contamination of the fluid.
- the acquisition of the first data can be carried out continuously, for example, in freely definable interval steps on an electrical energy transmission device.
- a filling or removal of a fluid into or from the container can generally be provided at times that are comparatively long apart.
- a plurality of measurements are carried out to determine the first data in an interval between the times provided for filling in the fluid or removing the fluid from the container.
- the number of data points contained in the first data should be greater than the number of data points contained in the second data.
- a dimensionless quantity can be used for the data, but masses, densities, dielectric strengths, pressures, etc. can also be compared with one another.
- the first or second data can be subjected to a corresponding normalization before or after processing.
- the first and second data can be related to the standard environment in order to eliminate external influences.
- a further advantageous embodiment of the method can provide that identifiers of measuring means are assigned to the first and / or second data.
- Corresponding measuring devices can be used to collect the first and second data.
- Measuring devices are, for example, density meters, flow meters, temperature-compensated pressure gauges, scales, etc.
- the measuring devices are assigned identifiers that can be transmitted with the data they determine or linked to this data .
- the identifiers can for example be serial numbers, registration numbers or other codes or the like.
- calibration records or calibration records can also serve as identifiers, by means of which a sufficient quality of the collected data can be ensured. This avoids, for example, the use of measuring devices of different qualities from complementing or compensating for measuring errors, which could limit the reliability of the monitoring method.
- the collection of the second data can take place at different times from different people with different measuring devices at different locations.
- a container is only given a pre-filling, for example for transport purposes, with the container being completely filled after delivery and installation.
- the amount of fluid remaining within the container is documented by balancing the amount of fluid supplied or any amount of fluid removed. This, in turn, can be compared with the measured values of the amount of fluid present in the form of the first data, thus providing proof of quality for the density of the container.
- a further advantageous embodiment can provide that time markers relating to the point in time at which the data was collected are assigned to the first and / or second data.
- Providing the data with time markers makes it possible to provide a time resolution of the data. This makes it possible to track changes or to create trends or forecasts.
- a prognosis can be made based on the amount of fluid present, which was measured and is mapped in the first data, and the behavior of the fluid during one or more intervals.
- a temporal classification of the filling and removal of fluids from the container using the second data in comparison to the measured first data can also be taken into account in such a forecast.
- Using the time markers it is also possible to look at different intervals if necessary.
- a time marker can, for example, be made available by a switching device or linked to the data, which has various interfaces, for example, in order to determine the measured values which are to be used first
- Such a switching device can be, for example, an "internet of things (IOT) gateway" which has various interfaces and can be connected to sensors, measuring equipment or the like.
- IOT Internet of things
- Using a switching device makes it possible to use inexpensive sensors (measuring probes, measuring equipment ) and to format their signals into standardized data forms via a connection to the switching device.
- analog measuring probes whose information is delivered to the switching device.
- advises for example, to be transmitted in a standardized data protocol.
- the data protocol can have a time marker. The time marker can be added to the data log.
- a time marker can be assigned as additional information to the fluid quantity mapped in the first data.
- further variables can also be added to the first data by means of the switching device. For example, it is possible to add a location coordinate, temperature information, etc. to the first data.
- the first data enriched in this way via the original information on the amount of fluid in the container can then be transferred by the switching device, for example, to a computer cloud, within which the first data, which depict the amount of fluid in the container, with second data, which is the in the Containers introduced or removed amount of fluid from, processed or compared.
- Part of the computer cloud can also be, for example, a portable device with which, in particular with wireless coupling, the information of the first or second data and a comparison resulting therefrom can be displayed.
- this portable device can also enable the graphical representation of the information in the first data or second data or the comparison that is established.
- a container usually has a leakage rate which, based on experience, occurs over many years of operation.
- a leak can be understood as a tolerance value, since it usually and typically occurs on a container.
- the tolerance value can be used to correct the determined deviation or the first data. It is thus possible, for example, that, as a function of the ongoing operation of the container, a determined deviation can be traced back to the aging of the container, for example. In the event of a deviation within a tolerance band, no activity is necessary. Thus, the use of a tolerance value makes it possible to prevent unnecessary actions such as repair measures and the like.
- the tolerance value can be designed to be dynamically variable. With an increase in the time spans of filling a container with a fluid, this tolerance can be increased in value (e.g.% loss per unit of time * period of time). The tolerance value can be reset by refilling the fluid.
- a further advantageous embodiment can provide that the first data and / or the second data and / or the determined discrepancy between the first and second data is / are documented in a manipulation-proof manner.
- the first data or the second data or the determined deviation can be processed within a computing device.
- a computing device can, for example, be located in a computer cloud or also on a local computer.
- documentation or proof of these fluids is advantageous to third parties.
- a manipulation-proof documentation of the data or deviations gen make it possible to make this data available to third parties in a trust-building manner or to enable this data to be called up by the third party.
- the tamper-proof data can, for example, be stored on a separate system, for example of a trustee, and thus enable documentation of the whereabouts of a fluid.
- a third party can also directly access or initiate a determination of first data and / or second data as well as a comparison of the same.
- a further advantageous embodiment can provide that the first data and / or the second data and / or the determined discrepancy between the first and second data is / are made available to third parties.
- Third parties can be test organizations, for example, by means of which the condition of the container is monitored. Third parties can also be authorities, for example, which require proof of the whereabouts of the fluid. It can be made available in such a way that the third party has direct access to the first or second data as well as the comparison and / or access to measurement protocols. For this purpose, it can be provided that a separate memory area is used in order to temporarily store the results of the monitoring method there in a manner that is as tamper-proof as possible in a neutral location. However, this information can also be available locally. Different locations should be preferred in parallel can be used to store the same information and thus further reduce the possibility of manipulation. A "blockchain", for example, can be used for this purpose.
- a further advantageous embodiment can provide that the first data and / or the second data and / or the determined discrepancy between first and second data according to station and / or field and / or container and / or filling quantity and / or time marker and / or Fluid amount can be represented.
- the fluid or the container can be part of an electrical energy transmission device which has different containers. Different containers can in turn be part of a higher-level field, with the field again being part of a higher-level station. It is thus possible, depending on the hierarchy level, to provide different granularities in the representation of the first or second data or the determined deviation. Furthermore, information about the filling amount and the currently measured amount of fluid can be displayed within the container. Such a presentation can take place, for example, in graphic form.
- the first or second data or the determined deviation can be graphically represented in a time curve. If necessary, the time axes can have a shorter or longer interval, e.g. B. hours, days, weeks, months, years, etc. represent. If necessary, the first data and the second data as well as the determined deviation can be used for a prognosis in order to determine a trend from the measured data, on the basis of which any maintenance work etc. to be carried out can be triggered if necessary.
- Another object of the invention is to provide a suitable device which can efficiently use the above-mentioned method.
- An electrical energy transmission device is used to transmit electrical energy.
- an electrical current is conducted in a phase conductor.
- This phase conductor with its corresponding potential difference must be electrically isolated from its surroundings.
- the phase conductor can be arranged, for example, at least in sections within the container, where the electrically insulating fluid flows around it.
- the volume enclosed by a container can be assumed to be constant, which makes it possible to use the density of a fluid that is enclosed within the constant volume of the container to make statements about an increase or decrease in the amount of fluid (for example in a mass quantity measured) is possible.
- the density can be used to infer the mass of the current fluid present within the container, so that initial data can be mapped.
- the first data can be provided in a standardized form via a switching device of the electrical energy transmission device.
- the first data on the switching device can also be supplemented with location information, temperature information, etc., so that the first data can be present, for example, in a standardized form, for example a specific data protocol, so that these first data, for example, are also transmitted and evaluated accordingly .

- the first data 11, the second data 12 and the deviation 13 can preferably be stored in a secure memory and can be retrieved there in a manner protected against manipulation. Access to this memory area can also be granted to third parties, for example, by automatically sending these logs to the third party or by actively requesting them from third parties from the memory. Third parties can also directly access the data in raw or processed form, so that there is an uninterrupted chain the detection of the whereabouts of fluid from one of the containers la, lb, lc is given.
- monitoring can also take place by combining the information from several containers 1 a, 1 b, 1 c, a whole switch panel, several switch panels of a switching station.
- a selection can be made, for example, using location coordination, which can be assigned to the first data 11 and the second data 12.
- location coordination can be assigned to the first data 11 and the second data 12.
- data generated in close proximity to one another can be summarized and supplemented to form an overall statement.
