Description
직류 철도는 그 전압 체계로 인해 그에 맞춰진 특수한 선로 설비에 국한되어 사용된다. 승객에게 가능한 한 쾌적한 여행 차편을 제공할 수 있도록 하기 위해, 다수의 체계에 맞춰질 수 있는 전동차가 점점 더 강하게 요구되고 있다. 그러한 유형의 전동차에 의하면, 상이한 전압 체계(상이한 세기의 직류 전압, 상이한 세기 및 주파수의 교류 전압)에서의 운전이 가능하다. 열차 또는 다수의 전동차를 나중에 추가의 전압 체계(제2 전압 체계)에 맞춰 개조하는 것은 대부분 매우 복잡하다. 그러한 개조 방안의 경제성은 필요로 하는 높은 개조 비용에 밀리기 일쑤이다..DC railroads are used exclusively for special rail installations due to their voltage regime. In order to be able to provide passengers with the most comfortable travel vehicle, there is an increasing demand for electric vehicles that can be adapted to multiple systems. With this type of electric vehicle, it is possible to operate in different voltage schemes (DC voltages of different intensities, AC voltages of different intensities and frequencies). Retrofitting a train or multiple trains later to an additional voltage scheme (second voltage scheme) is most often complex. The economics of such retrofits are often driven by the high cost of retrofitting.
선택적으로, 추가의 전압 체계(제2 전압 체계)에 적합한 기관차를 열차 또는 다수의 전동차에 연결하는 것이 가능하다. 그러나, 추가의 전압 체계(제2 전압 체계)를 위한 기관차가 연결된 열차 또는 전동차의 운전은 불리하게도 그에 의해 형성된 열차 무리가 원하는 주행 역학을 보이지 못하는 결과를 가져온다.Optionally, it is possible to connect a locomotive suitable for an additional voltage scheme (second voltage regime) to a train or multiple electric vehicles. However, the operation of a train or electric vehicle to which a locomotive for an additional voltage system (second voltage system) is connected disadvantageously results in that the group of trains formed thereby do not exhibit the desired driving dynamics.
본 발명은 전압 형태 및 전압 세기가 미리 주어진 제1 전압 체계용 구동 유닛을 구비한 열차 또는 다수의 전동차의 전기 에너지 공급 시스템에 관한 것이다.The present invention relates to an electrical energy supply system of a train or a plurality of electric vehicles having a drive unit for a first voltage scheme in which voltage form and voltage strength are given in advance.
이하, 본 발명을 첨부 도면에 도시된 실시예에 의거하여 더욱 상세히 설명하기로 한다. 첨부 도면 중에서,Hereinafter, the present invention will be described in more detail based on the embodiments shown in the accompanying drawings. Among the accompanying drawings,
도 1은 자체 운행이 가능한 에너지 공급 차량이 연결된 열차를 나타낸 도면이고,1 is a view showing a train connected to a self-driving energy supply vehicle,
도 2는 자체 운행이 불가능한 에너지 공급 차량이 연결된 열차를 나타낸 도면이다.FIG. 2 is a diagram illustrating a train to which an energy supply vehicle that is unable to operate itself is connected.
본 발명의 목적은 제1 전압 체계에서의 운전에 맞춰진 열차 또는 다수의 전동차의 전기 에너지 공급 시스템으로서, 추가의 전압 체계(제2 전압 체계)에서의 운전을 가능하게 하는 간단한 구조로 된 그러한 전기 에너지 공급 시스템을 제공하는 것이다.An object of the present invention is an electrical energy supply system of a train or a plurality of electric vehicles, which is adapted for operation in a first voltage scheme, such electrical energy having a simple structure that enables operation in an additional voltage scheme (second voltage scheme). To provide a supply system.
그러한 목적은 열차 또는 다수의 전동차에 기계적으로 및 전기적으로 연결되고, 전압 형태 및 전압 세기가 미리 주어진 하나 이상의 제2 전압 체계의 전기 에너지를 태핑(tapping)하여 제1 전압 체계의 전기 에너지로 전환하기 위한 유닛을 구비하는 별개의 에너지 공급 차량에 의해 달성된다.Such an object is mechanically and electrically connected to a train or a plurality of trains, and tapping the electrical energy of one or more second voltage schemes, given a voltage form and voltage strength in advance, to convert them into electrical energy of the first voltage scheme. Achieved by a separate energy supply vehicle having a unit for the same.
본 발명에 의해 얻어질 수 있는 장점은 제안된 바와 같이 열차 또는 다수의 전동차에 연결되는 별개의 에너지 공급 차량에 의해 기존 차량(열차 또는 다수의 전동차)에서의 개조 비용이 최소한으로 국한된다는데 있다. 단지 에너지 공급용 커플링만 설치되면 된다.An advantage that can be obtained by the present invention is that the cost of retrofitting in existing vehicles (trains or trains) is limited to a minimum by means of a separate energy supply vehicle which is connected to the train or trains as described. Only an energy supply coupling needs to be installed.
본 발명의 바람직한 구성은 종속 청구항들에 특징져 있다.Preferred configurations of the invention are characterized in the dependent claims.
제안된 바와 같은 열차 또는 다수의 전동차의 전기 에너지 공급 시스템의 또 다른 장점은 이후의 설명으로부터 확연해 질 것이다.Another advantage of the electric energy supply system of a train or a plurality of electric vehicles as proposed will be apparent from the following description.
도 1에는 자체 운행이 가능한 에너지 공급 차량이 연결된 열차가 도시되어 있다. 2대의 차량으로 이뤄진 열차(1)(또는 다수의 전동차(1))를 찾아볼 수 있는데, 그 경우에 각각의 차량은 구동 유닛(2)을 구비한다. 그러한 구동 유닛(2)은 전압 형태 및 전압 세기가 미리 주어진 제1 전압 체계(예컨대, 세기가 미리 주어진 직류 전압)에 맞춰 설계된 것이다. 열차(1) 또는 다수의 전동차에는 하나 이상의 별개의 에너지 공급 차량(3)이 기계적으로 및 전기적으로 연결된다.1 shows a train to which a self-driving energy supply vehicle is connected. A train 1 consisting of two vehicles (or a plurality of electric vehicles 1) can be found, in which case each vehicle has a drive unit 2. Such a drive unit 2 is designed for a first voltage scheme (eg a direct current voltage given a strength in advance) of a voltage type and voltage strength. One or more separate energy supply vehicles 3 are mechanically and electrically connected to the train 1 or to a plurality of electric vehicles.
하나 이상의 에너지 공급 차량(3)은 전압 형태 및 전압 세기가 미리 주어진 제2 전압 체계(예컨대, 주파수 및 세기가 미리 주어진 교류 전압)의 전기 에너지를 제1 전압 체계의 전기 에너지로 전환하기 위한 유닛(4)을 구비한다. 그러한 유닛(4)은 예컨대 전류 집전기(7)에 의해 접촉 전선(contact wire)(8)의 1차 교류 전압을 공급받아 인입 커넥터(6)에 2차 교류 전압을 제공하는 변압기(5)로 이뤄진다.The at least one energy supply vehicle 3 comprises a unit for converting electrical energy of a second voltage scheme (e.g., an alternating voltage with a predetermined frequency and intensity) into electrical energy of the first voltage scheme. 4) is provided. Such a unit 4 is for example a transformer 5 which receives the primary alternating voltage of the contact wire 8 by means of a current collector 7 and provides the secondary alternating voltage to the inlet connector 6. It is done.
인입 커넥터(6)로부터 제공되는 직류 전압은 모든 차량(1, 3)을 통과하여 마련된 열차 버스 바(bus bar)(11)에 공급되는데, 그 경우에 차량(1, 3) 사이의 전기 접속은 전기 커플링(10)에 의해 이뤄진다. 그와 동시에, 전기 커플링(10)은 차량(1, 3) 사이의 기계 커플링까지 포함할 수 있다. 그러한 기계 및 전기커플링(10)은 전자동으로 형성되어 인력의 투입이 없이 매우 간단하게 차량(1, 3) 사이의 연결이 가능하게 되도록 할 수 있는 것이 바람직하다.The direct current voltage provided from the inlet connector 6 is supplied to a train bus bar 11 provided through all the vehicles 1, 3, in which case the electrical connection between the vehicles 1, 3 is By electrical coupling 10. At the same time, the electrical coupling 10 can also comprise a mechanical coupling between the vehicles 1, 3. It is preferable that such mechanical and electrical couplings 10 can be formed fully automatically so that the connection between the vehicles 1, 3 can be made very simple without the input of manpower.
도 1에 따른 실시예의 경우, 하나 이상의 에너지 공급 차량(3)은 자체 운행이 가능하다. 즉, 열차 버스 바(11)에 접속된 구동 유닛(9) 및 자체 제동 설비를 구비한다. 물론, 하나 이상의 에너지 공급 차량(3)은 구동 및 제동 설비에 필요한 제반 제어 및 보조 장치도 구비한다.In the case of the embodiment according to FIG. 1, the one or more energy supply vehicles 3 are self-driving. That is, the drive unit 9 and self-braking facility connected to the train bus bar 11 are provided. Of course, the one or more energy supply vehicles 3 also have all the control and auxiliary devices required for the drive and braking installations.
도 2에는 자체 운행이 불가능한 에너지 공급 차량(3)이 연결된 열차가 도시되어 있다. 본 실시예는 도 1에 따른 실시예에 상응하는 것이지만, 다만 자체 구동 유닛(9)이 빠져 있다. 필요하다면, 제어 장치를 비롯한 제동 설비도 마련될 수 있다. 에너지 공급 차량은 에너지를 공급받은 전동차(1)(또는 열차)에 의해 이동된다.2 shows a train to which an energy supply vehicle 3 which is not self-driving is connected. This embodiment corresponds to the embodiment according to FIG. 1, but with its own drive unit 9 missing. If necessary, braking arrangements, including control devices, may also be provided. The energy supply vehicle is moved by the energized electric vehicle 1 (or train).
이미 전술된 설명으로부터 알 수 있는 바와 같이, 하나 이상의 에너지 공급 차량(3)은 필요한 제2 전압 체계에서의 운전에 맞춰 설계되어 있다. 그러한 하나 이상의 에너지 공급 차량(3)의 입력 회로는 그 하나 이상의 차량(3)이 차량 접합부에 있는 해당 전기 커플링(10)을 경유하여 연결 전동차(1)(또는 열차)에 전기 구동 에너지를 공급할 수 있도록 추가의 전압 체계에 맞춰 설계된다. 차량 접합부에 제공되는 전기 에너지는 전압 형태 및 전압 세기에 있어서 공급 대상 전동차(1)(또는 열차)의 제1 전압 체계에 해당된다. 차량은 통상적으로 Usmax= 1400 V로 운행된다; 커플링을 경유하여 전압을 전달할 경우에는 Us= 1600 V로 운전될 수도 있다. 그럼으로써, 에너지를 공급받는 전동차(1)(또는 열차)의 구동 유닛(2) 및 보조 유닛 군이 가용될 수 있게 된다. 에너지 공급 차량(3)을 부급전(negative feeding)이 가능하게 설계함으로써 에너지를 공급받는 전동차(1)(또는 열차)에도 부급전 가능성을 제공하는 것이 바람직하다.As can be seen from the foregoing description, one or more energy supply vehicles 3 are designed for operation in the required second voltage regime. The input circuit of one or more energy supplying vehicles 3 is such that the one or more vehicles 3 can supply electrical drive energy to the connecting electric vehicle 1 (or train) via the corresponding electrical coupling 10 at the vehicle junction. It is designed for additional voltage schemes. The electrical energy provided to the vehicle junction corresponds to the first voltage system of the electric vehicle 1 (or train) to be supplied in terms of voltage form and voltage intensity. The vehicle typically runs at U smax = 1400 V; In case of transferring voltage via the coupling, it may be operated at U s = 1600 V. Thereby, the drive unit 2 and the auxiliary unit group of the electric vehicle 1 (or train) to which energy is supplied can be made available. By designing the energy supply vehicle 3 to be capable of negative feeding, it is desirable to provide the possibility of secondary feeding to the electric vehicle 1 (or train) to which energy is supplied.
도면에는 단일의 에너지 공급 차량(3)이 도시되어 있지만, 에너지 공급 차량은 그와는 다르게 다수로 나눠진 열차일 수도 있다.Although a single energy supply vehicle 3 is shown in the figure, the energy supply vehicle may alternatively be a train divided into a plurality.
