description

Arrangement for an electricity meter with an audio frequency ripple control receiver integrated in the meter housing.

The invention relates to an electricity meter with an audio frequency ripple control receiver integrated in the meter housing, which influences bistable switching means for reversing the tariff facilities.

Such electricity meters are known, e.g. from DE-OS 23 02 754, in which an electricity meter is summarized with a ripple control receiver. This arrangement is used to switch a double tariff counter, saving space compared to conventional separate arrangements. The ripple control receiver can be retrofitted into any tariff meter.

For such counters, when installing the device at the energy consumer, it is necessary that the relay for switching the double tariff counter is set to the counting position that exists at that time.

To do this, the relay must be accessible. I.e. the counter must be opened in order to set it mechanically in the valid counting position.

Before installing an electricity meter at the energy consumer, each meter must be officially certified, i.e. the meter must be tested in the test center. In the case of the two tariff meter, both tariff meters must have registered a predefined consumption quantity, the maximum also runs for the maximum meter, and both maxima for the double double meter to check the exact registration. This check takes place at well-known test stations that draw energy from the grid and are therefore also accessible to the ripple control. However, it must be ensured that there is no tariff changeover during the test or the tariff changeover must not be effective for the meters to be checked in order to achieve exact test results. After such a check, the meters are provided with a so-called certification seal and are therefore no longer accessible.

• · · r 2 • »

With today's miniaturization of the components, it is possible to use an audio frequency ripple control receiver with a number of switching means required for the tariff circuits, e.g. bistable miniature relays, to be arranged on a module within the electricity meter. This makes it difficult to access the switchgear after the certification seal.

The invention was based on the object for electricity meters with an integrated audio frequency ripple control receiver to make the switching means accessible outside of the audio frequency control option for testing and installation purposes, even in the case of meters already provided with a certification seal.

This object is achieved by the invention as set out in the characterizing part of the first claim. The subclaims describe further advantageous measures.

The invention is explained in more detail below on the basis of a basic circuit diagram. The circuit diagram only shows the elements necessary for understanding the invention. The representation of the drive systems of the meter and their connection circuits are generally known and omitted for a better overview.

For electricity meters (Z) with an integrated audio frequency ripple control receiver (TF), n bistable switching means (R1 ... Rn) are provided to switch over n double or multiple tariff meters or maximum equipment (T1 ... Tn). These switching means (R1 ... Rn) are controlled by signaling via the power distribution network, the control signals (S) being fed to a signal decoding and command comparison device (DEC) via filters. This device (DEC) has the task of decoding the commands, comparing them with the stored data and forwarding the command, i.e. to control the assigned switching means (R1 ... Rn) in the desired position. The contacts (r1 ... rn) of the switching means then control the tariff devices (T1 ... Tn) of the meter via amplifiers (V1 ... Vn).

* · · 3 | Γ

In order to be able to influence the tariff devices (T1 ... Tn) for test purposes and to set them in the correct position when installing a meter, the control lines of the tariff devices (T1 ... Tn) are additionally connected via potential isolating modules (P1 .. .Pn) on free or additional terminals (K1 ... Kn) of the terminal block of the meter (Z). This means that the switching means (R1 ... Rn) and the tariff facilities (T1 ... Tn) are accessible electrically. Since the terminal block is sealed after the installation of a meter, manipulation is not possible.

By applying a voltage pulse to one of the terminals (K1 ... Kn), which is converted into a low-voltage switching pulse via the assigned potential isolating module (P1 ... Pn), the corresponding switching means (R1 ... Rn) is converted into the controlled another position and in parallel the connected tariff facility (T1 ... Tn) switched. The state achieved in this way is stored by the switching means (R1 ... Rn) or its contact (r1 ... rn) until the next control pulse is given.

In order to prevent the switching of the tariff devices (T1 ... Tn) by ripple control pulses of the energy distribution network during a metrological test of meters (Z), the signal decoding and command comparison device (DEC) is, for example, not connected to an inhibition link negated input, the control signals (S) of the ripple control are placed and its negated input is connected to another free terminal (Kn + 1). During the test of a counter, permanent potential is applied to this terminal (Kn + 1), which means that the ripple control receiver (TF) is switched practically insensitive.

Bistable card relays are preferably used as switching means (R1 ... Rn). When a pulse is given by mains voltage pulses to the terminals (K1 ... Kn), the relays (R1 ... Rn) each take the other switching position, i.e. their contacts (r1 ... rn) are open or closed. If the pulse length is increased considerably, so that over a period of e.g. greater than 5sec. Potential at the relays (R1 ... Rn), they are controlled in a defined starting position, which is characterized, for example, by * f t r * · »open contacts (r1 ... rn).

These two functions of relay control by means of different pulse lengths allow the tariff devices (T1 ... Tn) to be set when the meter is installed at the energy consumer and by applying long pulses as well as permanent potential to the audio frequency ripple control receiver (TF) known test stations.

The respective position of the relays (R1 ... Rn) or the tariff facilities (T1 ... Tn) are indicated by LEDs.

Instead of occupying additional or free terminals of the counter block, optical control by means of light pulses can also be implemented. In this case, preferably only one optical receiver is linked to the relays (R1 ... Rn) via corresponding conversion modules, a setting or test sequence for the individual tariff devices (T1 ... Tn) being controlled in a cyclical sequence. The advance to the individual relays can be controlled by giving impulses of different lengths and the relays can be set to the individual positions by coding.

A sealable flap or encryption based on data exchange between the command comparison memory or another device memory (DEC) and a light transmitter prevents deliberate manipulations.

Instead of leading the control lines out via terminals, a keyboard or a shift lever arrangement can also be used, which likewise guarantee the aforementioned criteria, the electrical access to the switching means controlling the tariff devices (T1 ... Tn). Such a keyboard or a shift lever arrangement is then also secured against tampering by a sealable cover.
