<p>The current operated circuit breaker (1) is located in a measuring compartment (a) of the meter, while in its terminal box (b) there is an actuator lever (12) of this switch. Its permanent terminal (15) is attached to the internal end of output terminal (b3), while the flexible terminal (16) is connected to the first end of the flexible, power conductive terminal panel (14), having its other end via a copper mesh (a2) connected to the first end of the current coil (a1) of the measurement system inside meter (A). The coil spring (17) pushes the flexible terminal (16) against the permanent terminal (15), while during shutdown the actuator lever (12) acts in the opposite sense upon an actuator rod (13) to terminal panel (14). The actuator rod (13) leads through an opening in the partitioning wall between the measurement area (a) and the terminal box (b). The current operated circuit breaker is made as a minimum version, so that the size of the meter remains unchanged. It is installed in such a way that it provides a long-term high level of cleanness on the terminal surfaces.</p> |
