Description

Electricity meter with double tariff counter For the delivery of electrical Energy to medium-sized and small consumers comes according to the current state of the art three basic tariffs into consideration.

According to the one tariff, the electricity supply is charged for each a special electricity price for the use of light and power, possibly with a discount guarantee if a certain power consumption is exceeded (tariff according to purpose and graduated tariff).

According to the second tariff will be different at different times of the day high electricity prices for light and for power or charged for one of the two (Time double and time multiple tariff).

According to the third tariff, those who are independent of electricity generation so the fixed costs. to the pantograph regardless of his electricity consumption fixed rates are charged (basic fee tariff).

Each of these types of electricity billing has disadvantages can be avoided in a combination.

The object of the invention is to create a measuring device, which combines the second and third tariff types, while the graduated tariff after -, like before in the usual way mathematically, can be combined with it. An embodiment reproduces the drawing.

Let e be the voltage iron of a single-phase alternating current meter, i its Main stream iron, t the rotating disk, from its shaft in a known manner the switchable axis a1 of a double tariff counter 1, 11 is driven.

Such double tariff counters were previously used in ..the double tariff either from a timer (double time tariff) or from a main power or Wattrelais (block tariff) controlled.

The invention uses the double tar if counter for the connection of basic fee and double time tariff and is therefore used for switching from counter I to 1I and vice versa two control organs.

First of all, the counter I is driven from axis a via the gears zz. After delivery of a certain set watt-hour amount z. B. by means of the worm and the wheel counter set s, S., r, y and the lever h, and switch hl k ', a resistor w ,, which is in the circuit of a switching magnet in, short-circuited, thereby the magnet na, strongly excited and the axis a., with gear z at z, decoupled from meter I and connected to meter II via z.

The further power output beyond the set watt-hour amount is therefore measured on the II counter.

Up to this point, the facility provides a set-off based on the basic fee tariff which is not based on the connection value, meter size or number of rooms, the basic fee is chosen, but according to the easily recorded number of watt-hours that each consumer to has to relate to that part of the fixed costs plus the To pay generation costs for this number of watt-hours. Whether this number is a minor decrease Should be guaranteed, is the responsibility of the electricity supplier. The greater mobility those with the proposed basic fee key compared to the determination of the Basic charge is given according to connection value, meter size or number of rooms, does this not necessarily required.

The interchangeability of the wheels r, r, and the choice of where to start of lever 1z until switching is initiated by closing k, k ' the possibility of easily introducing tariff changes as required.

The electricity to be measured at the meter II only has the pure electricity generation costs plus reserve and profit.

The price for this can therefore be very high, regardless of the purpose should be set low. This means that there is a further division into daytime and night-time electricity not mandatory.

Only during the few hours of high factory load (blocking time) this very low electricity price is not acceptable for the plant.

The invention therefore provides for the counter to be reset for the blocking time from meter II to meter I before by z. B. by one of a timer in a known manner energized relay Y a switch located in the circuit wi m1 s switched from z to i and thereby .the circuit is opened. The during The amount of electricity delivered during the blocking period is therefore sent to the counter I for high tariffs and only the amount of electricity delivered outside of this time to the meter II for low Tariff measured.

The counter III indicated in the drawing gives the possibility of using a main current magnet or a wattrelais na, (block relay) via the drawn short-circuit device k2 k. k% to short-circuit the resistance w, of a relay circuit of the relay nz ". and thus measure the amount of electricity drawn above a predetermined wattage limit separately at the meter III and to charge it increased (block tariff). By choosing a shorter switching distance from z to z3 compared to the distance zz , counters I and II are out of operation; as long as counter III is switched on.

The electricity supplier is generally only interested in electricity consumption only to be limited upwards within a high factory load. In the rest. Time every level of electricity consumption is desirable to him, even at low prices. So only about m3 to keep energized during this time of high factory load (blocking time), the already mentioned switch s of the timer controlled relay y double-pole executed.

Outside the blocking period, the switch is open according to the drawing Contact 2 and 4 .. So it is m, energized, but ms not, and the total power consumption is therefore counted on counter II.

During the blocking period, the switch to i and 3 is closed by means of relay r. So it's ara, not excited, but m3. Up to the block boundary to which the Block relay m is set, so the current output to meter I, via this Block boundary measured at register III.

With the three counters, the drawing represents a counter, which combines the basic tariff, time double tariff and block tariff in a simple way.

The widely used and justified discount based on the amount of total consumption can be calculated and deducted after the end of the year (graduated tariff). If the electricity supplier wants to measure the electricity output separately after the predetermined amount of watt-hours has been given within the blocking period, a counter with three counters can be used for this purpose, in which, if m. Lt. W; the relay in is switched directly by the counter timer. The relay r with switch s is therefore not required here. The exemplary embodiment according to the drawing shows electrical relays for the counter works and as a control element of the time switch. Nothing stands in the way of making these switchovers completely or partially purely mechanical or, conversely, switching h, k, k ', by means of relays.

Claims (3)

PATENT CLAIMS: i. Electricity meter with double tariff counter, whose Switchover from meter I to meter II after a certain amount of watt-hour has been consumed takes place, characterized in that after reaching the predetermined watt-hour amount an organ controlled by a timer during one set by the electricity supplier Time (blocking time) back control to the counter I causes. 2. Electricity meter according to claim i, characterized in that a third counter is attached to the counter is, which by the actuated by the timer control element during the blocking time is switched on and counters I and II are switched off. 3. Electricity meter according to claim i, characterized in that a third meter is attached to the meter, which is switched on after a certain block limit is exceeded, with the count value, 1 and II. Q .. Electricity meter according to claim 3, characterized in that the switching on the counter III intended for exceeding the block boundary is only carried out at a blocking time selected by the electricity supplier.
