Description
Дл отыскани у.есг замыканий на землю в трехфазных системах переменного тока или нарушени симметрии фаз примен ют трехфазныеэлектростатическиеThree phase electrostatic discharges are used to find out the ground fault circuits in three-phase AC systems or disrupting phase symmetry.
приборы, состо щие из ротора, выполненного из изол ционного материала , и системы неподвижных металлических электродов, расположенных иод углом 120 один относительно другого и присоединенных к проводам сети.devices consisting of a rotor made of an insulating material and a system of stationary metal electrodes located at an angle of 120 relative to each other and connected to the wires of the network.
Предлагаетс , согласно изобретению , использовать подобный прибор в качестве указател пор дка следовани фаз, что дает возможность непосредственно подключать его к сети высокого напр жени .According to the invention, it is proposed to use a similar device as an indicator of the order of the phases, which makes it possible to directly connect it to a high-voltage network.
На чертеже изображе} а принципиальна схема предлагаемого прибора.In the drawing, the image is a schematic diagram of the proposed device.
Прибор выполнен в виде системы неподвижных металлических электродов /, сдвинутых один относительно другого в пространстве на угол 120°, внутри которых расположен ротор 2 нз д 1электрика. Электроды 1 присоед11Н5:ютс к проводам трехфазной сети и создают вращающеес электрическое поле.The device is made in the form of a system of stationary metal electrodes /, which are displaced one relative to the other in space by an angle of 120 °, within which is located a rotor 2 ns d 1 of the electrician. Electrodes 1 connecting 11H5: they are connected to the wires of a three-phase network and create a rotating electric field.
При по влении такого нол на поверхности ротора 2 по вл ютс св занные зар ды, которые, взаимодейству с зар дами электродов, привод т ротор во вращение в сторону направлени пол . Если бы при вращении ротора не возникало трени о воздух и в подшипниках, то ютор в тащалс бы синхронно с полег.. Трение создает тормоз щий момент , и враи1ающеес поле «проскальзывает по поверхности ротора , вследствие чего он вращаетс аеинхронно с полем. Направление вращени ротора определ ет пор док чередовани фаз в сети.Upon the appearance of such a zero, associated charges appear on the surface of the rotor 2, which, interacting with the charges of the electrodes, cause the rotor to rotate in the direction of the field. If during the rotation of the rotor there was no friction against the air and in the bearings, the uter would drag in synchronization with the lag. The direction of rotation of the rotor determines the order of phase alternation in the network.
Предмет изобретени Subject invention
Применение многофазного элекростатичсского прибора, состо щего из статора с системой электродов , присоедин емых к фазным проводам электрической цепи и создающих вра1цаюн1,еес электрическое поле, и ротора, выполненного диэлектрика и приводимого ВО вращение указанным полем, в вани фаз в качестве указани пор дка следо- ческой цепи. многофазной электриThe use of a multi-phase electrostatic device, consisting of a stator with a system of electrodes, connected to the phase conductors of an electrical circuit and creating a virtual one, its electric field, and a rotor, made of a dielectric and driven by the indicated field, indicate the order of the next chesky chain. multiphase electric
