Definitions
- the invention relates to low-voltage circuit breakers arranged in the usual way on the lower connecting rails Iron converters for release purposes, optionally with a second converter for measuring functions can be equipped.
- Low-voltage circuit breakers are currently in the basic version with an iron converter with one for trip purposes sufficient accuracy, which is usually based on the lower connecting bar is arranged. It means that for a desired measuring function outside the circuit breaker separate transducers mounted on the busbar Need to become. It is also known in addition to the trigger function a measuring function using a combination converter to provide, such that an iron converter and a Rogowski converter can be arranged. It means that a Rogowski converter is generally required, even if no measuring function is required or that during manufacture already between switches with measuring function and those without Measurement function must be differentiated. But that means one significantly increased technological effort in Manufacturing area.
- the invention is therefore based on the problem of low-voltage circuit breakers to create the optional only with transducers for a trigger function or additionally with Transducers can be equipped for a measuring function without for this an additional manufacturing effort at the switch is required or the transducer outside the switch in the switchgear, e.g. mounted on the busbar must become.
- the low-voltage circuit breaker according to the invention contains only an iron converter in its basic version sufficient accuracy for triggering purposes. This is expediently in the usual way on the lower connecting rail arranged. If one measuring function is desired, a second one is used Converter, advantageously a Rogowski converter, with associated Evaluation electronics retrofitted, and also in Circuit breaker arranged.
- this second converter is on the same Connection rail of the circuit breaker arranged as the Tripping converter, the one previously provided for this Assembly room is designed accordingly enlarged.
- the second transducer as a transducer can also be useful on the other, usually upper, connecting rail be arranged, here a corresponding assembly room is provided.
- the one that is preferably designed as a Rogowski converter Transducer is with the associated evaluation electronics executed and required as an independent unit no calibration when installed in the circuit breaker.
- FIG. 1 shows schematically a low-voltage circuit breaker with the solution according to the invention of installing both Transducer on a connecting rail in section.
- FIG. 2 shows schematically a low-voltage circuit breaker with the inventive solution of installing the Transducer on different connecting rails in average.
- the low-voltage circuit breaker shown schematically in FIG. 1 1 contains one in its basic version Iron converter 2 with one sufficient for triggering purposes Accuracy. This is in the usual way on the lower one Connection rail 3 arranged. Via the electrical signal lines 4 is the iron converter 2 for triggering purposes with the normal protection module 5 of the circuit breaker connected. Of the The mounting space 6 provided for this converter 2 is so large trained that if necessary, another converter for a measuring function can be installed. Is that need given, a Rogowski converter 7 is on the same Connection rail 3 of the circuit breaker, such as the iron transformer 2 arranged for triggering purposes. This is for this intended mounting space 6, as mentioned, accordingly enlarged. The Rogowski converter 7 is via signal lines 8 connected to associated evaluation electronics 9.
- FIG. 2 shows a switch according to the invention, where the Rogowski converter 7 on the upper connecting rail 10 of the circuit breaker is arranged, for which purpose a corresponding Assembly room 11 on the upper connecting rail is provided.
- the converter 7 is by means of signal lines 8 connected to the associated evaluation electronics 9. Also at This type of installation is the Rogowski converter on the input rail when the switch for maintenance and Repair work without tension.
- the advantages of the invention are that only one basic switch for the installation of only one converter, as well what is needed for the installation of two transducers manufacturing technology simplifications. It can be decided at any time whether a converter is required for a measuring function and this can then be retrofitted without any problems.
