Description

모드별 철도차량용 게이트드라이브의 시험장치Test device for gate drive for railway vehicles by mode
발명은 모드별 철도차량용 게이트드라이브의 시험장치에 관한 것으로서, 더욱 상세하게는 철도차량용 게이트드라이브의 출력전압 및 출력파형을 측정하여 철도차량용 게이트드라이브의 양부 판정이 가능한 모드별 철도차량용 게이트드라이브의 시험장치에 관한 것이다.The present invention relates to a test apparatus for a gate drive for a railway vehicle for each mode, and more particularly, to a test apparatus for a gate drive for a railway vehicle for each mode capable of judging whether the gate drive for a railway vehicle is judged by measuring the output voltage and the output waveform of the gate drive for the railway vehicle. It is about.
최신 철도차량은 전기 전력을 동력의 공급원으로 하는 전기차량이 주종을 이루고 있으며, Modern railway vehicles are mainly composed of electric vehicles that use electric power as a power source.
첨단 반도체 기술의 발전으로 마이크로 프로세서의 전기전자 제어를 통해 철도차량의 운행에 필요한 동력 및 전력을 공급하기 위한 여러 가지 형태의 전력변환 장치가 사용되고 있다.With the development of advanced semiconductor technology, various types of power converters are being used to supply the power and power required for the operation of railroad cars through the electronic control of microprocessors.
그 중 가장 대표적인 장치는 대용량 추진제어장치로 제어 부품은 PCB형태의 모듈화된 장치로 이루어져 있으며, 자동차에서 엔진에 해당하는 장치로 철도차량의 핵심 주요장치 이다.Among them, the most representative device is a large-capacity propulsion control device, and the control part is composed of a modular device in the form of PCB.
전기철도차량이 주행하는데 필요한 전력을 변환시켜 견인전동기에 공급하는 추진제어장치는 콘트롤 유닛, 구동부, 대용량 전력반도체로 구성되어 있다.The propulsion control device that converts the electric power required to drive the electric railway vehicle and supplies it to the traction motor is composed of a control unit, a driving unit, and a large-capacity power semiconductor.
철도차량용 대용량 전력반도체는 ON/OFF의 스위칭을 통해 견인전동기를 제어하는데, 이를 구동시키기 위해서는 게이트를 매우 짧은 시간동안 고속 스위칭 ON/OFF 하는 구동부에 해당하는 게이트 드라이브라는 부품을 사용하며, 게이트 드라이브의 스위칭 작용 시 열발생으로 기계적, 전기적 특성변화가 일어나 기동 불가 등 차량의 성능과 영업운행 시 심각한 고장등의 영향을 미치게 된다.Large capacity power semiconductors for railway vehicles control traction motors by switching ON / OFF. To drive them, a part called gate drive corresponding to the driving part that switches the gate on and off at high speed for a very short time is used. Heat generated during switching action causes mechanical and electrical characteristics to change, affecting the performance of vehicles such as impossibility of starting and serious breakdowns during operation.
따라서 운행거리 및 시간에 따라 주기적으로 부품의 진단과 유지보수가 있어야만 안정적인 철도차량을 운행할 수 있어야 하는데, 운행중 우발적 고장에만 대응하는 것이 현실이다. Therefore, it is necessary to periodically diagnose and maintain parts according to the driving distance and time so that a stable railroad vehicle can be operated, and the reality is that it only responds to accidental failure during operation.
또한, 게이트 드라이브는 운행중 내 외부 온도환경에 의해 각종 오동작 및 열화적 고장이 발생하고 있으며, 이에 대한 유지보수자들의 대책은 원인규명과 열화진단을 하는데 많은 어려움이 있는 실정이며, 대부분의 게이트 드라이브는 차체 하부에 취부되어 노출된 박스형태의 모듈화를 이루고 있어 완전 밀폐가 어려워 환경적 영향을 에어컨이나 히터 등이 설치된 차량 내부보다 많이 받게 되는데, 이러한 고장유형이 우리나라와 같은 계절적 편차가 클 때에 따라 빈도수도 달라지는 경향이 있다.In addition, the gate drive causes various malfunctions and thermal failures due to the internal and external temperature environment during operation, and the countermeasures of the maintainers have many difficulties in determining the cause and diagnosing the degradation. As it is modular in the form of exposed box mounted on the lower part of the body, it is difficult to be completely sealed, so the environmental impact is more affected than the inside of a vehicle equipped with an air conditioner or a heater. It tends to be different.
아울러, 종래의 게이트드라이브 단품의 시험은 실시가 불가능하여, 컨버터나 인버터 내부에 취부되어 전체 동작을 테스트 하며, 운행 중 불량 발생 시 에도 별다른 진단 없이 신품을 단순교환 하는 것이 일반적인 유지보수 방식이다.In addition, it is impossible to carry out the conventional test of the gate drive alone, so it is installed inside the converter or inverter to test the whole operation, and in the case of a failure during operation, it is a general maintenance method to simply replace the new product without any diagnosis.
이를 해결하기 위해, 운행환경과 구성에 맞게 모드별로 시험이 가능하며, 주기적 유지보수를 보다 효율적으로 시행하기 위한 기술이 필요한 실정이다.In order to solve this problem, it is possible to test for each mode according to the operating environment and configuration, and technology for performing periodic maintenance more efficiently is required.
