Description

В насто щее врем  известны способы передачи энергии трехфазным переменным током по .системе „два провода- земл .At present, methods are known for transmitting energy by three-phase alternating current through a “two wire-to-ground” system.

Така  передача может быть применена только дл  линий низкого напр жени  не ответственного значени  и при сравнительно небольшой их нагрузке (линии сельскохоз йственного значени ).Such transmission can be applied only for low voltage lines of non-critical value and with their relatively small load (agricultural value lines).

Наиболее существенными недостатками передачи энерТии по системе „два провода-земл   вл ютс  несимметри  напр жений, наличие токов в земле, вредно вли ющие на работу телеграфных и телефонных линий и опасность частых выключений и перерывов в подаче энергии, так как вс кое заземление одного из двух проводов превращаетс  в двухфазное короткое замыкание.The most significant shortcomings of energy transfer through the system, the two wires-to-ground, are the asymmetry of voltages, the presence of currents in the earth, which adversely affect the operation of the telegraph and telephone lines and the danger of frequent shutdowns and interruptions in power supply, since the wire turns into a two-phase short circuit.

Дл  устранени  этих недостатков, согласно предлагаемому изобретению, над проводами прокладываетс  трос из электропроводного материала, который заземл етс  на каждой опоре или через р д опор, а перед входом ни подстанцию прокладываетс  в земле и присоедин етс  к одному из зажимов трансформатора .To eliminate these drawbacks, according to the present invention, a wire is laid above the wires of electrically conductive material, which is grounded on each support or through a series of supports, and in front of the entrance no substation is laid in the ground and connected to one of the transformer clamps.

Вследствие взаимной индукции между тросом и двум  проводами значительна  часть тока будет удерживатьс  в тросе (остальна  пойдет по земле), что соответственно уменьшает несимметрию на (371)Due to the mutual induction between the cable and the two wires, a significant part of the current will be held in the cable (the rest will go along the ground), which accordingly reduces asymmetry by (371)

пр жений и вли ние тока в земле на провода слабого тока.stresses and the effect of current in the ground on the wires of low current.

Наличие троса, расположенного выще проводов и притом заземленного, дает хорошую защиту от грозовых разр дов, а благодар  этому значительно уменьшаетс  число перекрытий на линии, а следовательно, и число аварийных выключений .The presence of a cable located above the wires and, moreover, grounded, provides good protection against lightning discharges, and due to this the number of overlaps on the line, and consequently, the number of emergency shutdowns, is significantly reduced.

Трос заземл етс  помощью наклонных отт жек, расположенных в плоскости троса и спускающихс  на столб на высоте 3-4 метров от уровн  земли. Это дает возможность почти целиком использовать изол цию дерева траверсы и вертикальные части столба выше места креплени  к нему отт жек. Во избежание прикосновени  к несущим рабочий ток отт жкам, последние должны быть закрыты сверху дерев нной планкой на высоте 3-4 метров от уровн  земли.The cable is grounded using inclined cables located in the plane of the cable and descending onto a pole at a height of 3-4 meters from ground level. This makes it possible to almost completely use the insulation of the traverse tree and the vertical parts of the pillar above the point of attachment to it. In order to avoid contact with the carrying current currents, the latter should be closed on top of the wooden plank at a height of 3-4 meters from ground level.

Изобретение должно позволить получить значительную экономию в цветных металлах, изол торах и дереве. Кроме того, ширина трассы уменьшаетс  примерно в полтора раза.The invention should allow significant savings in non-ferrous metals, insulators and wood. In addition, the path width is reduced by about one and a half.
