Embodiment Construction

[0026] refer to figure 1 and 2 , the electric meter 1 of the present invention is used to measure the electric energy provided by the power distribution network located upstream of the electric meter 1 and consumed by the electrical facilities located downstream of the electric meter 1 . The electrical energy is delivered to the electrical installation through a wire having a live wire 2 and a neutral wire to which the meter 1 is connected.

[0027] The electricity meter 1 has a cutting element 3 connected to a live wire 2 inside the electricity meter 1 . The disconnecting element 3 is used to connect and disconnect the electrical installation from the distribution network selectively and under remote control.

[0028] The closed state of the cut-off element 3 (in figure 1 shown in ) and disconnected state (in figure 2 shown in ) can be set by the electricity supplier (or by the administrator of the network).

[0029] The disconnecting element 3 has a stationary metal co...

Abstract

An electricity meter comprising estimator means for estimating the closing and opening delays of a disconnection element (3), said estimator means comprising: a resonant inductive circuit (6) with a possible a coil (10) mounted by the moving contact (5); sending means arranged to send voltage pulses to said inductive circuit; detector means arranged to detect voltage from the output of the inductive circuit damping the oscillating voltage signal (So), and depending on the number of oscillations to detect the position of the movable contact (5) and thereby detect the actual opening or actual closing of the disconnecting element; and for measuring the opening command and detecting Measuring device for the time between the actual opening and the time between the closing command and the detection of the actual closing.

Description

technical field [0001] The invention relates to the field of electric meters. Background technique [0002] Modern electricity meters are so-called "smart" meters, which are of course adapted to measure the amount of electrical energy supplied by distributors to electrical installations via the distribution network, but are also able to perform a certain number of additional functions: management of tariffs by receiving commands; Meter for remote reading and programming; customer remote data, etc. [0003] These meters sometimes include disconnecting elements connected to the live wire and making possible remote action to selectively connect and disconnect electrical installations and distribution networks. [0004] Disconnecting elements are used inter alia to protect electrical installations by opening when the electrical installation is subjected to unexpected power surges from the distribution network and by acting to reclose after the unexpected power surges and at the...
