Clamp block for certification testing of electricity consumption meter |
摘要 |
The clamp block has at least one clamp arrangement (4), which has a current clamp (7,8) for connecting the meter to a lead of a phase of an electric supply network and for connecting a current path (2) of a measuring mechanism of the meter. The arrangement also has a voltage clamp (9) for connecting a voltage path of the measuring mechanism. The voltage clamp is connected to the current clamp via a releasable contact bridge. The contact bridge is accessible from the front side of the clamp block. The releasable contact bridge has at least one contact element formed as a spring. The free end of the spring preferably lies against a contact surface provided on a further contact element. One of the two contact elements is preferably connected to the current clamp while the other is connected to the voltage clamp.
