Definitions

• the invention relates to an arrangement for the remote-controlled monitoring and influencing of an electronic overcurrent release of an electrical circuit breaker, the overcurrent release having an interface for outputting status reports and for receiving control commands and connecting the interface to a transmission line
• the invention has for its object to make the care of circuit breakers and overcurrent releases by a central control room much cheaper and technically simpler.
• the transmission line is part of a network connecting data processing devices and that the interface of the overcurrent release is set up for the exchange of data in accordance with the TCP / IP protocol series in HTML format.
• Switch is provided, which enables or blocks a change in Ausioser parameters by means of data transmission via the interface. In this way, access by the manufacturer can be discussed with the operator of the circuit breaker within a tight time frame, thus preventing unauthorized access.
• encryption algorithms, passwords or similar security features can be used, such as are also used in banking transactions on the Internet.
• the data processing scope of a page in HTML format is relatively small. This fact can be evaluated within the scope of the invention in such a way that at least one for a memory area of the overcurrent release
• the HTML page provided is saved. This has the advantage that the amount of data to be transferred can be limited as required. This results in a significant saving of storage space on average compared to the fact that a page required for the largest data record is used. It also has an advantageous effect if the memory area mentioned is designed to be readable and writable for calling up and storing at least one HTML page. In this case, the operator and manufacturer or maintenance service of the circuit breaker can store or replace customized HTML pages in the overcurrent release.
• the figure shows a circuit breaker LSI, a further circuit breaker LS2 and, with the omission of the immediately following order numbers, a further circuit breaker LSn.
• Each of these circuit breakers has an overcurrent release Ul, U2 or Un, which is equipped with an interface Sl, S2, Sn.
• the circuit breakers LSI, LS2 and LSn are connected to networks NW1, NW2, which are formed by local sections of the Internet.
• NW1 and NW2 are spatially far apart and can be located on different continents, for example.
• they are connected via antennas AI and A2 to a satellite S, which ensures the constant availability of the connection.
• Modem cards enable data exchange between a public telephone network that is accessible everywhere and the Internet.
• the case is considered that an operator of circuit breakers would like to commission the manufacturer to check the associated overcurrent release and to modify the setting of parameters, if this appears necessary.
• This can be done by the operator sending the manufacturer a written, telephone or transmitted message via the network NW1 or NW2.
• the operator specifies the period of time during which the maintenance work is to be carried out or agrees to make the overcurrent release accessible for data transmission via the network NW1 or NW2 at a certain time on request.
• the manufacturer now uses his data processing device, e.g. B. PCI, in the same way by entering an Internet address contact with the electrical system of the operator, as is the case with other information and data services on the Internet.
• the manufacturer By selecting the relevant overcurrent release Ul, U2 etc., the manufacturer now receives a screen display of the registered processes.
• the scope of this registration depends on the requirements of the operator and / or the manufacturer and requires the overcurrent release to be equipped with a data memory. Data of interest in the present context can in particular be tripping with indication of the overcurrent.
• the manufacturer can in the data processing device Data stored in PCI or an external database DB determine whether the trips are within a predetermined range or whether it is expedient to set changed trip parameters, taking into account the configuration of the operator's system. If this results, the
• the overcurrent release Ul can be set directly by transferring a changed set of parameters.
• the operator can carry out the
• Maintenance work on the data processing device PCI appears, is preferably at least one page in HTML format, which is stored in a memory area of the selected overcurrent release, such as memory area SP1 in the overcurrent release U1 of the circuit breaker LSI.
• This HTML page forms the framework and the user interface for reading and changing data. It can be provided that the user of the circuit breaker himself provides the HTML page and thus specifies which data is accessible as part of the maintenance.
• such a configuration can also be selected that the manufacturer of the circuit breaker or the commissioned maintenance service provides the HTML page and, if necessary, exchanges or changes in the course of the maintenance work. This is because of it possible that the memory area is writable and the write mode is enabled or can be enabled by password transmission.
