Description
Išradimas priskiriamas elektros matavimų sričiai ir gali būti naudojamas nustatant suvartotos energijos kainą, t y. pinigų sumą, kurią turi sumokėti vartotojas už elektros energiją, tiekiamą keičiamu laiko bėgyje apmokėjimo tarifu, ypač kai grupė vartotojų išsidėstę geografiškai nedideliame plote.The invention is within the scope of electrical measurements and can be used to determine the cost of energy consumed, i.e.. the amount of money that a consumer has to pay for electricity supplied at a variable rate over time, especially when a group of consumers are spread over a geographically small area.
Žinomi daugiatarifiniai elektros energijos registravimo skaitikliai, sudaryti mažiausiai iš dviejų skirtingo jautrumo registratorių, kuriuos perjungia laikrodinio tipo mechanizmas (Šveicarijos patento CH679078 aprašymas,išradimo liudijimo SU 1765776 aprašymas). Tačiau šie skaitikliai sudėtingi, brangūs ir nepakankamai patikimi masiniam naudojimui. Be to, tokie skaitikliai turi konstrukcijos apibrėžtą tarifų skaičių. Taip pat žinomas elektros energijos, apmokamos keičiamais tarifais, kainos nustatymo įrenginys (SU 1821747), turintis vientarifinius elektroindukcinius skaitiklius, prie kurių įtampos kontaktų pajungiama vartotojo įtampa, o prie srovės kontaktų-tarifinio koeficiento keitiklio-srovės transformatoriaus apvijų, kurios turi po tris užtrumpinamas relėmis sekcijas, galai. Šiame įrenginyje pirmojo tarifo laike energija Ai matuojama su proporcingumo koeficientu lygiu 1, o energija kitais intervalais Ą - su koeficientu —, kur ą - tarifas tame laiko intervale.Known multi-tariff electricity recording meters comprising at least two sensors of different sensitivity, which are switched by a clock-type mechanism (Swiss patent specification CH679078, description of patent application SU 1765776). However, these meters are complex, expensive and not reliable enough for mass use. In addition, such meters have a design-defined number of tariffs. Also known is a variable-rate electricity pricing device (SU 1821747) having single-rate electro-inductance meters, to which the voltage contacts are connected to the consumer voltage, and to the current-to-rate converter-to-current transformer windings, each having three short-circuit relays. sections, ends. In this device, the energy Ai at the first tariff time is measured with a proportionality factor equal to 1 and the energy at other intervals ą with the factor - where ą is the tariff at that time interval.
Elektros energijos kaina B randama iš sąryšioThe cost of electricity B is obtained from the relation
B-ai(A,+A2+A3+...Ą), oB's (A, + A 2 + A 3 + ... +), o
A= At.A = A t .
kur At - tikrasis suvartotos energijos kiekis,where A t is the actual amount of energy consumed,
A, , Ao - sąlyginis energijos kiekis, registruojamas skaitiklio.A,, Ao is the relative amount of energy recorded by the meter.
įrenginyje naudojamo elektrinio skaitiklio judančioj! dalis yra metalinis diskas, mechaniškai sujungtas su skaitikliu. Diską suka elektroindukcinė sistema, sudaryta iš sroves I (nuoseklaus jungimo) ir įtampos U (lygiagretaus jungimo) apvijų. Sukamasis momentas Ms, kuris proporcingas skaitiklio parodymams, aprašomas sąryšiumoving meter of the electric meter used in the unit! part is a metal disk mechanically connected to the meter. The disk is rotated by an electro-inductive system consisting of current I (serial connection) and voltage U (parallel connection) windings. The torque M s , which is proportional to the meter reading, is described by the relationship
Ms= 01Φ1Φ2008φ1 = C2lUC0S<p2 kur Φ! ir Φ2 - srovės ir įtampos apvijų magnetiniai srautai,M s = 0 1 Φ 1 Φ 2 008φ 1 = C2lUC0S <p 2 where Φ! and Φ 2 is the magnetic flux of the current and voltage windings,

Tačiau šis įrenginys tinka tik ribotam, konstrukcijos apibrėžtam tarifų skaičiui, kuris negali būti keičiamas eksploatacijos melu, nepatogus centralizuotam daugelio vartotojų tarifo keitimui. Be to, įrenginio konstrukcija sudėtinga ir brangi, nes tarifinio koeficiento keitiklio funkcijai atlikti naudojam! specialūs srovės transformatoriai.However, this device is only suitable for a limited, design-defined number of tariffs, which cannot be replaced by service lies, inconvenient for centralized multi-user tariff changes. In addition, the construction of the unit is complicated and expensive, because we use the tariff coefficient converter function! special current transformers.
Išradimo uždavinys-užtikrinti galimybę keisti tarifų skaičių įrenginio eksploatacijos metu ir centralizuotai keisti grupės vartotojų tarifą automatiškai informuojant vartotoją, supaprastinti ir atpiginti įrenginio konstrukciją.The object of the invention is to ensure the possibility to change the number of tariffs during the operation of the equipment and to centrally change the tariff of the group users by automatically informing the user, to simplify and reduce the construction of the equipment.
Šį uždavinį išsprendžia elektros energijos, apmokamos keičiamais tarifais, kainos nustatymo įrenginys, kuriame kaina B nustatoma pagal išraiškąThis problem is solved by a variable-rate electricity pricing device, where price B is determined by the expression

Aj is the amount of energy consumed, a, ą - tariffs at time intervals, with single-rate electro-induction meters with a rate coefficient converter, in that the rate coefficient converter is a common voltage divider for all meters connected to the voltage winding of the meters by a tariff wire, which gives the condition U
