Description
Изобретение относится к устройств вам рудничного транспорта, в частности к энергоприемным устройствам бесконтактных электровозов переменного тока повышенной частоты.The invention relates to devices for mine transport, in particular to power receivers of non-contact electric locomotives of alternating current of increased frequency.
Известен энеогоприемник бескон- : тактного электровоза повышенной частоты, состоящий из многовитковой обмотки, уложенной в секции магнитопровода параллельно тяговой сети СП.The known power receiver is a non-contact : tact electric locomotive of increased frequency, consisting of a multi-turn winding laid in a section of the magnetic circuit parallel to the traction network of the joint venture.
Недостатком этого устройства явля- V ется наличие значительного магнитного потока многовитковой обмотки, замыкающегося через зазоры магнитной цепи и взаимодействующего с посторонними контурами рудничной среды, а также ’ низкие энергетические показатели вследствие потерь мощности в магнитопроводах, ферромагнитных элементах и наличия потокосцепления взаимной индукции между витками секции, что 21 повышает энергозатраты.The disadvantage of this device is the presence of a significant magnetic flux of a multi-turn winding, which closes through the gaps of the magnetic circuit and interacts with extraneous contours of the mine environment, as well as low energy performance due to power losses in the magnetic circuits, ferromagnetic elements and the presence of flux linkage of mutual induction between the turns of the section, which 21 increases energy costs.
Цель изобретения - снижение энергозатрат.The purpose of the invention is the reduction of energy consumption.
Поставленная цель достигается тем, +то обмотка выполнена из отдельных отрезков коаксиального провода, причем внутренний проводник каждого из отрезков в секции соединен с внешним проводником другого отрезка, а внешний и внутренний проводники отрезков одной секции соединены соответственно с внешним и внутренним проводниками отрезков другой секции.This goal is achieved by the fact that + the winding is made of separate pieces of coaxial wire, with the inner conductor of each of the sections in the section connected to the outer conductor of the other section, and the outer and inner conductors of the sections of one section connected respectively to the outer and inner conductors of the sections of another section.
На чертеже показан энергоприемник бесконтактного электровоза повышенной частоты.The drawing shows the power receiver of a contactless electric locomotive of increased frequency.
Энергоприемник бесконтактного электровоза повышенной частоты состоит из основания 1, на котором укреплены П-образные магнитопроводы 2, в которых параллельно кабелям тяговой линии 3 уложены последовательно соединенные в обмотку витки 4 из отрезков коаксиальных проводов, содержащих внешний 5 и внутренний 6 проводники.The power receiver of a non-contact electric locomotive of increased frequency consists of a base 1, on which U-shaped magnetic cores 2 are mounted, in which coils 4 from segments of coaxial wires containing external 5 and internal 6 conductors are laid in series with the cables of the traction line 3.
Устройство работает следующим образом.The device operates as follows.
Магнитное поле переменного тока повышенной частоты тяговой линии 3 наводит во внешних проводниках 5 каждого витка электродвижущую силу. Внешние проводники 5 экранируют внутренние проводники 6 витков от проникающего извне магнитного поля тока тяговой линии 3 (поверхностный эффект в проводящей среде). Электродвижущая сила обмотки равна сумме электродвижущих сил витков 4. Ток нагруженного энергоприемника, проте!кая противоположнонаправленро по внешнему и внутреннему проводникам 5 и 6 коаксиальной пары, не создает снаружи ее и всей обмотки магнитного поля. Полная индуктивность обмотки равна сумме индуктивностей витков.An alternating current magnetic field of increased frequency of the traction line 3 induces an electromotive force in the outer conductors 5 of each turn. The outer conductors 5 shield the inner conductors of 6 turns from an external magnetic field of the current of the traction line 3 (surface effect in a conductive medium). The electromotive force of the winding is equal to the sum of the electromotive forces of the turns 4. The current of the loaded energy receiver, flowing in the opposite direction along the outer and inner conductors 5 and 6 of the coaxial pair, does not create outside of it and the entire winding of the magnetic field. The total inductance of the winding is equal to the sum of the inductances of the turns.
Предлагаемый энергоприемник по сравнению с известным имеет преимущества. Отсутствие внешнего магнит·* ного поля витков и обмотки· исключает: потокосцепление с посторонними контурами рудничной среды (уменьшение опасности искрообразования и электротравматизма от наводимых в них ЭДС), воздействие магнитного поля на обслуживающей персонал - что обеспечивает безопасную эксплуатацию электровозов; повышает КПД энергоприемника на 18,7&’, уменьшает установленную реактивную мощность компенсирующих конденсаторов в число раз, пропорциональное числу витков в секции обмотки, и се5 чение магнитной цепи в число раз, равное числу витков обмотки, - что сокращает установленное на электровозе оборудование на сумму 9,68 тыс.р,The proposed energy receiver in comparison with the known has advantages. The absence of an external magnetic field * * of turns and windings · eliminates: flux linkage with extraneous contours of the mine environment (reducing the risk of sparking and electric injuries from EMF induced in them), the effect of a magnetic field on maintenance personnel - which ensures the safe operation of electric locomotives; increases the efficiency of the energy receiver by 18.7 & ', reduces the installed reactive power of the compensating capacitors by a factor proportional to the number of turns in the winding section, and the cross-section of the magnetic circuit by a factor equal to the number of turns of the winding, which reduces the amount of equipment installed on the electric locomotive by 9 , 68 thousand rubles,
