Abstract

Invention applies to the public electricity supply. The proposed new diagram and starting method of the electric generator allows the use of a low-power capacity electric motor, this way, saving expensive fuel and oils and at the same time securing the environment against pollutants. The proposed diagram of the electric generator includes the use of an alternating-current motor as an exciting motor and the connection of the exciting motor to the generator through a reduction gear. Besides, to the generator can be attached the second alternating-current motor, which through the second reduction gear may be connected to the second electric generator, one feeder of which through a knife switch is connected to the first alternating-current motor. To start the generator there can be used an additional energy source connecting it to the alternating-current motor or to the reduction gear coupling, directly to the electric generator itself.

Description

Išradimas susijęs su buitinės elektros energijos tiekimu.The invention relates to the supply of household electricity.

Žinomos elektros generatorių jungimo schemos (Politechninis žodynas (rusų kalba) M., 1989 m., 152 pusi.),kuriose generatoriaus paleidimui naudojamas dizelinis variklis.Known circuits for generating electrical generators (Polytechnical Dictionary (Russian), M., 1989, 152 pages), using a diesel engine to start the generator.

Elektros generatoriaus paleidimui naudojamas dizelinis variklis degina brangų kurą, tepalus, teršia aplinką.The diesel engine used to start the electric generator burns expensive fuel, lubricants and pollutes the environment.

Siūloma nauja elektros generatoriaus jungimo schema ir jo paleidimo būdas leidžia panaudoti mažo galingumo elektros variklį, tokiu būdu sutaupant brangų kurą ir tepalus ir, tuo pačiu, apsaugant aplinką nuo teršalų.The proposed new electric generator circuit diagram and its start-up method allow the use of a low-power electric motor, thus saving on expensive fuel and lubricants, while protecting the environment from pollutants.

Siūloma elektros generatoriaus jungimo schema apima kintamosios srovės variklio panaudojimą kaip žadinimo variklio, jo sujungimą per reduktorių su elektros generatoriumi. Be to, prie generatoriaus gali būti prijungtas antras kintamosios srovės variklis, kuris per antrą reduktorių sujungtas su antruoju elektros generatoriumi, kurio viena maitinimo linija per kirtiklį sujungta su pirmuoju kintamosios srovės varikliu.The proposed electrical generator connection scheme involves the use of an AC motor as an excitation motor, its connection via a gearbox to an electric generator. In addition, a second AC motor can be connected to the generator, which is connected via a second reducer to a second electric generator, one power line of which is connected via a cutter to the first AC motor.

Elektros generatoriaus paleidimo metu pirmąjį kintamosios srovės variklį išjungia iš elektros tinklo ir sujungia antrąjį elektros generatorių su pirmuoju kintamosios srovės varikliu. Be to, generatoriaus paleidimui galima panaudoti papildomą energijos šaltinį, prijungiant jį arba prie kintamosios srovės variklio, arba prie reduktoriaus, arba prie paties elektros generatoriaus tiesiogiai.During start-up of the generator, the first AC motor is disconnected from the mains and connects the second generator to the first AC motor. In addition, an additional power source can be used to start the generator by connecting it either directly to the AC motor, to the reducer or to the power generator itself.

Kintamosios srovės variklis 1 turi pajungimo į elektros tinklą 2 laidus, ir per reduktorių 3 sujungtas su elektros generatoriumi 4 (Fig.1). Jungiant elektros variklį, pvz.: 3 kW galingumo ir 3000 aps/min, su elektros generatoriumi per 3 kartus mažinantį reduktorių, elektros generatoriaus apsukos sumažėja iki 1000 aps/min, o galingumas padidėja 3 kartus.The AC motor 1 has wires for connection to the mains 2 and is connected to the power generator 4 via the gear unit 3 (Fig.1). When connecting an electric motor, for example: 3 kW and 3000 rpm, with a generator through a 3-fold reduction gearbox, the electric generator speed is reduced to 1000 rpm and the power is increased by 3 times.

Kitame generatoriaus jungimo variante elektros generatorius 4 prijungtas prie 5 antro elektros variklio Γ, o pirmas elektros variklis 1 per kirtiklį 5 sujungtas su elektros tinklu 2 ir antruoju generatoriumi 4’ (Fig.2). Pirmą elektros variklį 1 per kirtiklį 5 įjungus į elektros tinklą 2, paleidžiamas generatorius 4, kuris pradeda gaminti elektros energiją ir perduoda ją į antrą elektros variklį Γ, kuris per reduktorių 3’ išsuka antrąjį generatorių 4’. Pradėjus dirbti elektros generatoriams 4 ir 4’, kirtiklis 5 perjungiamas nuo tinklo į elektros generatorių 4’.In another embodiment of the generator connection, the electric generator 4 is connected to the second electric motor Γ, and the first electric motor 1 is connected via a cut-off 5 to the mains 2 and the second generator 4 '(Fig. 2). When the first electric motor 1 is connected to the mains 2 via the cut-off 5, the generator 4 is started, which starts generating electricity and transmits it to the second electric motor Γ, which drives the second generator 4 'through the reducer 3'. When the power generators 4 and 4 'start to operate, the switch 5 is switched from the mains to the power generator 4'.

Prie kintamosios srovės variklio 1,1’ gali būti prijungtas papildomas energijos šaltinis 6, 6’ (Fig.3). Taip pat šis energijos šaltinis 6,6’ gali būti prijungtas arba prie reduktoriaus 3, 3’, arba prie generatoriaus 4, 4’. Papildomos energijos šaltiniu 6, 6’ gali būti suspausto oro balionas (deguonies balionas) su padavimo mazgu, kurį sudaro uždarame korpuse 7 ant ašies 8 pasukamai įtvirtinta sparnuote 9. Korpuse 7 yra oro išėjimo anga 10 ir oro padavimo štuceris 11. Suspaustas oras paduotas per oro padavimo angą 12 į korpusą 7 suka spanuotę 9, kuri per ašį 8 perduoda sukimąsi elektros varikliui 1. Ašis 8 su guoliais izoliuota ribokšliu 13. Pradėjus dirbti generatoriui 4, oras atjungiamas. Sėkmingai gali būti panaudoti ir kiti papildomi energijos šaltiniai.An additional power source 6, 6 'may be connected to the AC motor 1,1' (Fig. 3). Also, this power source 6,6 'can be connected to either the reducer 3, 3' or the generator 4, 4 '. The additional energy source 6, 6 'may be a compressed air balloon (oxygen cylinder) with a feed unit consisting of a rotatable impeller 9 in a closed housing 7 on an axis 8, the housing 7 having an air outlet 10 and an air supply shaft 11. the air supply opening 12 is rotated in a housing 7 by means of a flange 9 which transmits the rotation to the electric motor 1 through the axis 8. The shaft 8 with bearings is insulated by a stop 13. Other additional energy sources can also be used successfully.

Siūlomo išradimo naudingumas tame, kad atsisakoma dizelinio variklio, naudojančio brangų kurą, tepalus, teršiančius aplinką. Panaudojus mažo galingumo elektros variklį generatoriaus įsukimui arba jungiant kelis generatorius ir variklius į schemą, gaunama didelė elektros energijos ekonomija.The usefulness of the present invention is the elimination of a diesel engine using expensive fuels, lubricants that pollute the environment. Using a low power electric motor to drive the generator, or connecting multiple generators and motors to the circuit, results in significant electricity savings.
