Description

тропроводного материала (бетона, стекла, пластмасс и др.) с нанесением на ее внутреннюю поверхность электронроводного сло необходимой толщины. Электропроводный слой трубы 1 может быть выполнен в виде нескольких отдельных симметрично расположенных проводов, наход щихс в толщине стенки трубы.a conductive material (concrete, glass, plastics, etc.) with an electrically conducting layer of necessary thickness applied to its inner surface. The conductive layer of the pipe 1 can be made in the form of several separate symmetrically arranged wires located in the wall thickness of the pipe.

Центральный провоД 2 может быть выполнен расщепленным на два параллельных , так что оба проводника располагаютс в середине симметрично относительно осевой линии трубы 1 и плоскости рамки 5 приемника. При этом витки рамки 5 приемника энергии перекрещены в середине в виде восьмерки, а сама рамка 5 входит в трубу 1 на весь ее диаметр, что позвол ет при тех же габаритах (длине) увеличить напр жение на выходе витков приемника примерно в 2 раза.The central wire 2 can be made split into two parallel so that both conductors are located in the center symmetrically with respect to the center line of the pipe 1 and the plane of the frame 5 of the receiver. At the same time, the turns of the frame 5 of the energy receiver are crossed in the middle in the form of a figure eight, and the frame 5 itself enters the pipe 1 for its entire diameter, which allows, at the same dimensions (length), to increase the voltage at the output of the receiver coils by about 2 times.

В предлагаемой конструкции устройства напр женность электромагнитного пол вне габаритов трубы равна нулю (ноле отсутствует ), что исключает его воздействие на металлические тела, линии св зи, т. е. устран ет отмеченные выше недостатки. Устройство такой конструкции можно располагать как угодно близко к экипажу, рельсам, лини м св зи. Поскольку один из проводов закрыт, вс лини становитс более электробезопасной .In the proposed design of the device, the electromagnetic field strength outside the tube dimensions is zero (zero is absent), which excludes its effect on metallic bodies, communication lines, i.e., eliminates the disadvantages noted above. A device of this design can be positioned as close as possible to the crew, rails, lines of communication. As one of the wires is closed, the entire line becomes more electrically safe.

Отсутствие скольз щего электромеханического контакта позвол ет применить такие устройства дл передачи энергии на высокоскоростной подвижный состав рельсового типа (метрополитен, монорельсовые экипажи , экипажи на магнитном подвешивании и т. д.), а также на промышленные и шахтные электровозы, работающие в услови х искроопасных по пыли и газу.The absence of a sliding electromechanical contact allows the use of such devices for transmitting energy to high-speed rail-type rolling stock (underground, monorail crews, magnetic suspension crews, etc.), as well as to industrial and mine electric locomotives operating under dust and gas.
