Description

철도차량의 DC 리니어 추진시스템{DC linear propulsion system for a railway}DC linear propulsion system for a railway

본 발명은 철도차량의 DC 리니어 추진시스템에 관한 것으로, 특히 비점착 구동방식에 의해 가감속 성능을 향상시킬 수 있는 철도차량의 DC 리니어 추진시스템에 관한 것이다.
The present invention relates to a DC linear propulsion system of a railway vehicle, and more particularly, to a DC linear propulsion system of a railway vehicle capable of improving acceleration / deceleration performance by a non-adhesive driving method.

일반적으로 철도차량의 가감속 성능은 차량의 무게와 추진장치의 성능을 고려하여 설정되며, 정차역이 많은 우리나라의 경우에 가감속 성능 향상은 운행시격 및 전체 소요시간 단축에 핵심이 된다.In general, the acceleration / deceleration performance of a railway car is set considering the weight of the vehicle and the performance of the propulsion unit. In the case of the station having a lot of stopping stations, the acceleration / deceleration performance improvement is a key to the operation of the vehicle and the reduction of the total travel time.

일반 철도차량은 휠온레일(Wheel On Rail) 방식으로 점착 구동방식을 사용하므로 점착한계(약 430km/h) 이상으로는 속도의 한계가 있다.The general railway vehicle uses the wheel-on-rail type adhesive driving method, so there is a speed limit above the sticking limit (about 430 km / h).

전기 철도차량은 직류 또는 교류 전력을 공급받아서 주전원장치를 통해 견인전동기를 구동하게 되며, 보조전원장치(SIV)를 통하여 공조시스템, 전등, 통신 등의 차내에 필요한 전기를 공급하게 된다.Electric railway vehicles are supplied with direct current or alternating current power to drive the traction motor through the main power supply, and supply the necessary electricity in the vehicle such as air conditioning systems, lights, and communications through the auxiliary power supply (SIV).

견인전동기에서 발생된 토크는 감속기어를 통하여 고토크 저속의 기계적 에너지를 변환되며, 이는 열차의 바퀴와 레일 사이의 마찰력에 의해 추진력을 발생시키게 된다.The torque generated by the traction motor is converted to mechanical energy of high torque and low speed through the reduction gear, which generates the driving force by the friction between the wheels of the train and the rail.

특히, 가속 또는 감속 구간에서는 큰 토크와 제동력을 필요로 하지만 실주행 구간에서는 그 보다는 낮은 토크만을 필요로 하므로, 일반적으로 견인전동기는 실주행에 요구되는 연속정격으로 설계와 제작이 이루어지고 있다.In particular, a large torque and a braking force are required in the acceleration or deceleration section, but only a lower torque is required in the actual running section. Therefore, the traction motor is generally designed and manufactured at a continuous rating required for actual travel.

기동시는 견인전동기의 연속정격보다 많은 전류를 투입하여 견인력을 발생시키게 되지만 순시정격은 약 1.5 ~ 2배로 한계가 있다.When starting, it generates more traction by injecting more current than the continuous rating of the traction motor, but the instantaneous rating is limited to about 1.5 to 2 times.

따라서 종래의 전기 철도차량은 추진장치의 용량 한계, 차량의 중량, 전력공급의 한계, 점착 한계 등에 의한 가감속 성능 또는 초고속 주행 개선에 많은 어려움이 존재한다.Therefore, the conventional electric railway vehicle has a great difficulty in acceleration / deceleration performance due to the capacity limit of the propulsion device, the weight of the vehicle, the limit of the power supply, the adhesion limit, or the improvement of the high-speed driving.

예를 들어, 가감속 성능 향상을 위하여 큰 용량의 견인전동기를 사용할 수가 있으나, 가감속 구간 이외의 일반주행 구간에서는 차량의 중량 증가로 인하여 오히려 주행 효율을 떨어뜨리게 된다.For example, a large-capacity traction motor can be used to improve acceleration / deceleration performance, but the driving efficiency is lowered due to an increase in the weight of the vehicle in a normal driving section other than the acceleration / deceleration section.

이를 회피하기 위하여 출력밀도를 높인 견인전동기를 사용하는 경우에는 차량의 중량 증가 문제점은 해결될 수 있으나, 차량 내 전력공급의 한계와 전차선의 용량 증대로 인하여 현실적으로 적용하기는 어려움이 있다.In the case of using a traction motor having an increased output density to avoid this problem, the problem of increasing the weight of the vehicle can be solved, but it is difficult to apply the present invention due to the limitation of the power supply in the vehicle and the capacity of the catenary.

또한 초고속 주행 성능 향상을 위하여 큰 용량의 견인전동기를 적용하더라도 휠온레일 방식에서의 점착 한계로 인하여 바퀴가 미끄러지므로 초고속 주행이 불가한 문제점 등이 있다.In addition, even if a large-capacity traction motor is used to improve the super-high-speed driving performance, there is a problem that the super-high-speed driving is impossible because the wheels slide due to the adhesion limit in the wheel-

특히 본 발명에서 철도차량의 하부에 초전도 자석에 의해 제공되는 계자부는 단위 유니트로 모듈화되어 장착됨으로써 고장 시에 단위 유니트의 모듈 단위로 교체 또는 수리가 이루어질 수 있으므로 유지 및 관리가 용이하다.
In particular, in the present invention, the field portion provided by the superconducting magnet in the lower portion of the railroad vehicle is modularized and mounted in a unit unit, so that in case of failure, the field unit may be replaced or repaired by a unit of the unit, so that it is easy to maintain and manage.

전기자부(120)는 지상의 궤도를 따라서 마련되며, 궤도와 인접하여 마련되는 전력변환장치(130)에 의해 전원 공급이 이루어져 계자부(110)와의 상호작용에 의해 철도차량의 주행에 필요한 구동력을 발생시킨다.The armature unit 120 is provided along a track of the ground, and is supplied with power by the power converter 130 provided adjacent to the track to generate a driving force necessary for traveling of the railway vehicle by interaction with the field unit 110.

도 3의 (a)(b)는 본 발명에 따른 철도차량의 DC 리니어 추진시스템의 구동예를 설명하기 위한 도면으로, 전기자부(120)는 지상 궤도를 따라서 일정 구간마다 꼬임이 있도록 권선되어 전력변환장치에 전원이 인가되며, 철도차량 하부에는 각각 N, S극을 갖는 초전도자석(211)(212)이 단위유니트로 모듈화되어 계자부(210)를 구성하고 있다. 본 실시예에서는 설명의 편의를 위하여 하나의 단위유니트만으로 구성된 전기자부로 설명한다.Figure 3 (a) (b) is a view for explaining the driving example of the DC linear propulsion system of the railway vehicle according to the present invention, the armature portion 120 is wound so as to be twisted every predetermined section along the ground track power Power is applied to the converter, and superconducting magnets 211 and 212 having N and S poles, respectively, are modularized into a unit unit in the lower portion of the railroad car to form the field unit 210. In the present embodiment, for convenience of description, it will be described as an armature unit consisting of only one unit unit.

이와 같이 구성된 본 발명의 철도차량의 DC 리니어 추진시스템은 전력변환장치를 통해 전기자부(120)에 직류 펄스 전류(또는 구형파의 교류 전류)가 인가되면, 이 전기자부(120)에 인가된 직류 펄스 전류는 이동자계를 발생시키며 이러한 이동자계는 계자부(210)와 동기화되어 인가되도록 제어됨으로써 철도차량의 추진력을 제공하게 된다.
In the DC linear propulsion system of the railway vehicle of the present invention configured as described above, when a DC pulse current (or an AC current of a square wave) is applied to the armature unit 120 through a power converter, the DC pulse applied to the armature unit 120. The current generates a moving magnetic field, and the moving magnetic field is controlled to be applied in synchronization with the field unit 210 to provide a driving force of the railway vehicle.

이와 같이 구성된 본 발명의 철도차량의 DC 리니어 추진시스템은 철도차량 하부에 계자부를 설치하며, 지상궤도 사이에 전기자부를 마련하여 비점착 구동력에 의해 철도차량의 추진력을 제공할 수 있으므로 등판 구간 또는 가감속 구간의 성능을 높일 수 있으며, 또한 휠온 방식의 철도차량에 적용되어 초고속 주행이 가능하다.The DC linear propulsion system of the railway vehicle of the present invention configured as described above is provided with a magnetic field portion under the railway vehicle, and an armature portion is provided between the ground tracks so that the driving force of the railway vehicle can be provided by the non-adhesive driving force, so that the climbing section or the ramp is added or lowered. It is possible to increase the performance of the speed section, and is also applied to the wheel-on railway cars, which enables ultra-high speed driving.

또한 종래의 전기 철도차량의 추진시스템에서와 같은 전차선 및 팬터그래프와 같은 전력공급장치와, 변압기, 컨버터, 인버터 등의 전력변환장치와 회전형 견인전동기 및 기어 등의 에너지 변환장치를 차량에 탑재할 필요없이 지상궤도의 전기자부에 직접 전력을 공급하여 철도차량의 주행이 이루어지므로 철도차량을 경량화하여 가감속 능력을 개선하고 초고속 주행 성능 개선을 도모할 수 있다. In addition, it is necessary to mount a power supply device such as a catenary and pantograph as in a propulsion system of a conventional electric railway vehicle, a power converter such as a transformer, a converter, an inverter, and an energy converter such as a rotary traction motor and a gear. Since the railroad car is driven by directly supplying electric power to the armature of the ground track, it is possible to reduce the weight of the railroad car to improve acceleration / deceleration capability and to improve ultra-high speed driving performance.

또한 종래의 선형동기 전동기 추진에 비하여 직류 또는 구형파 교류 전력을 사용하게 되므로 전력 손실을 줄일 수 있으며 지상에서의 전력변환장치의 구성을 간단히 할 수 있는 장점이 있다.
In addition, since the use of direct current or square wave AC power as compared to the conventional linear synchronous motor propulsion can reduce the power loss and has the advantage of simplifying the configuration of the power converter on the ground.

이상에서 설명한 본 발명은 전술한 실시예 및 첨부된 도면에 의해 한정되는 것이 아니고, 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 여러 가지 치환, 변형 및 변경이 가능함은 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에게 명백할 것이다.
