Description

Device for comparing the count on the main knife in the Delivery plant and on the consumption meters for gas, water and electricity in distribution networks for gas, water, electricity etc. there is no possibility for the supplying works to to obtain a precisely accurate picture of the magnitude of the line losses that occur, although such knowledge is not only from the point of view of the company's profitability, but also in the interests of timely threat mitigation of far-reaching consequences Meaning is.

An exact loss determination can only be obtained if all consumption meters and the main knife can be read at the same time, both at the beginning as well as at the end of the period selected as the B, observation period. On the other hand, if you search to determine the line loss from those meter readings, which are determined by the meter reading officers admittedly next to each other in districts, but recorded one after the other in each district there is initially an arithmetical loss; but only part of this arithmetical loss is real loss, the other part is a sham, which is based on the mentioned non-simultaneity and is actually kept out would have to. 'To determine how large these two partial amounts are, for it there is no handle. So far, estimates have been used; but the scope for these estimates is so great in practice that one can see the real line losses can assume with the same degree of probability with zero or with 15%. There is also the fact that the reading errors occurring as a result of human weaknesses every l #, laughing test are inaccessible because the time to recheck the meter reading changed anyway.

The known automatically recording measuring devices can be used for do not use the aforementioned purpose, as on the one hand their acquisition costs are high are too high to be paid for at every customer. could set up such a device, and on the other hand the delicate mechanism of these apparatuses of careful maintenance requires a lot of staff.

According to the invention, a flawless and accurate determination the size of the line losses in a distribution network in a simple manner allows that on the main knife in the delivery plant. and on the consumption meters Pressure or voltage; g's: changes in the consumable, responsive pressure or Writing devices for automatic recording of the current meter reading can be provided, which are repeated at certain time intervals, or regularly arbitrarily, by changing the condition of the consumable (e.g. pressure wave, Current surge and the like) are put into action.

The simultaneous recording of the counters of several knives by action from a single point is known per se. however, in the known designs, this action takes place mechanically or electromagnetic i way. .

As a result: But these facilities are for the -inventive Purpose of use not usable.

A common mechanical release can at best be possible for several Carry out knives when they are close together, e.g. B. my laboratory, -a Factory space or the like are set up, but not for a large number of knives, which are set up so widely separated by streets and house walls, as it is the case with a city's consumption knife; the mechanical connections would get an almost impossible degree of foolishness.

A triggering of the knives' on elekbromagnetis: chem way comes therefore not considered for the present purpose, because then special control lines to the individual consumption meters. need to be relocated. D: he is necessary for this However, high costs can be achieved solely by the point of view of being worth striving for Monitoring of line losses cannot be economically justified.

These obstacles are overcome by the invention, which the VerbTauchsm @ ttel that is to be distributed is itself the carrier of the control effects. 'is, and any special lenunglen come to fruition. By the perfect -Simultaneous reading will be. furthermore, any reading shifts are avoided, so that a precise monitoring of the line losses in the entire network as well Nothing stands in the way of the individual cable strands. A wire will be downloaded in this way recognized as soon as it arises and can be stopped before it has reached dangerous proportions. In addition, reading errors are avoided the admission by the works officials prevented, since these numinehr only the automatically have to write off the record made and years: appropriate Records can be checked at any time: @Es is even the most useful Set up in such a way that the reading officers, who are also the Money lifters can be one at a time. Cards to a part designated for this purpose the counter is used on which then. later on the cut-off date from the knives the meter reading is automatically printed. The next time you pick up the Works officials only insert the printed cards, which @er replaces with fresh ones, whereupon the game repeats itself.

The processes in accordance with the invention on the main and consumption meters to be attached, to pressure waves or voltage surges or the like. Printing devices for recording the counter readings are without difficulty and can be manufactured at low cost. As switching elements are for example Pressure waves diaphragms and pistons, available during voltage surges relays displaceable writing or printing devices are known per se.

It is not just changes in voltage that are necessary for the purpose of actuating the Printing work can be superimposed on the normal river, but you can mine Direct current network the stewerungs; actions. with alternating current, in .an alternating current network the control; effects with direct current: give and at the place of use by known Facilities (capacitors, self-hiduction) ensure that every type of current only works in: the "for them specific I @ eitungsowcü; ge.
