본 발명은 전압 및 전류 측정을 통한 판토그래프와 전차선 접촉 모니터링 시스템 및 그 방법에 관한 것으로, 보다 상세하게는 철도 차량에 공급되는 전압 및 전류의 변화를 측정하여 판토그래프와 전차선의 집전상태를 검측함으로써, 전기적인 접촉의 계산을 통하여 좀 더 정확한 이선을 파악할 수 있는 전압 및 전류 측정을 통한 판토그래프와 전차선 접촉 모니터링 시스템 및 그 방법에 관한 것이다.
The present invention relates to a pantograph and a catenary contact monitoring system and a method through the measurement of voltage and current, and more particularly, by measuring the change in voltage and current supplied to a railroad vehicle by detecting the current collection state of the pantograph and the catenary. The present invention relates to a pantograph, a catenary contact monitoring system, and a method of measuring voltage and current through which electrical contact is calculated to obtain a more accurate two-wire.

일반적인 전기철도시스템은 선로에 공급되는 전기를 차량에 설치된 판토그래프를 이용하여 전차선으로부터 차량의 동력원에 전기를 공급하는 방법을 사용한다. 그러나, 가선의 처짐, 열차의 진동 및 바람에 의한 측풍 등으로 가선과 판토그래프의 이선의 발생으로 인해 원활한 전력 공급이 이루어지지 않는 경우가 종종 발생한다.A general electric railway system uses a method of supplying electricity to a power source of a vehicle from a catenary using a pantograph installed in a vehicle. However, in some cases, smooth power supply may not be achieved due to the occurrence of deflection of the overhead line, vibration of the train, side winds caused by wind, and the like.

종래의 이선을 측정하는 방법은 판토그래프가 가선에 미치는 압상력을 측정하여, 압상력이 어느 일정한 문턱값의 이하가 되었을 경우 이선이 발생한 것으로 판단하는 것이다. 그러나, 종래의 방법은 실제로 이선이 되지 않는 상황도 이선이라고 판단하는 오류를 범할 수 있으며, 전기적인 이선의 관점으로 보았을 때는 적절한 방법이라고 할 수 없다. 뿐만 아니라, 종래의 방법에서는 공력, 관성력 등을 고려하여 압상력을 계산하였다고 하더라도, 공력에 대한 부분이 부정확할 가능성이 높다. 압상력이 어느 문턱값의 이하인 경우로 계산하기 때문에, 앞서 설명한 바와 같이 실제로 이선이 되지 않았음에도 불구하고, 이선이 되었다고 판단할 수 있다.
The conventional method of measuring the two wires is to measure the rolling force applied to the false wire by the pantograph, and determine that the two wires have occurred when the rolling force falls below a certain threshold value. However, the conventional method can make an error that it is determined to be a second line even when the situation is not actually second line, and it cannot be said to be an appropriate method from the viewpoint of electric two lines. In addition, in the conventional method, even if the rolling force is calculated in consideration of aerodynamic force, inertia force, and the like, there is a high possibility that the portion of the aerodynamic force is inaccurate. Since the compressive force is calculated as the case below a certain threshold, it can be determined that the wire is in the wire even though the wire is not in the wire as described above.

도 3은 본 발명에 따른 판토그래프 전압에 따른 전류 파형의 예시도이다.3 is an exemplary view of a current waveform according to the pantograph voltage according to the present invention.

도 3을 참조하면, 판토그래프의 전압 변화에 따른 전류 파형을 볼 수 있다.Referring to FIG. 3, the current waveform according to the voltage change of the pantograph can be seen.

판토그래프를 통하여 유입되는 전압, 전류에 대한 등가 임피던스를 Zeq로 표현을 하면, Zeq는 인덕턴스 성분인 Leq, 저항성분인 Req, 커패시턴스 성분인 Ceq로 구성되어 있다. 가선에서의 전압이 일반적으로 AC 정현파인 25kv가 인가된다고 하였을 때, 이선이 발생하지 않은 경우에는 판토그래프에 인가되는 전압은 25kv이고, 전류는 등가 임피던스인 Zeq에 따라 흐르게 된다. 그러나, 이선이 발생하게 되면, 판토그래프에 인가되는 전압은 커패시턴스 성분 Ceq때문에 순간적으로 감소되지 않고, 유지하게 되나, 전류는 0으로 떨어지게 된다. 전류가 0으로 떨어진 부분에서, 어느 정도 일정시간이 지나면 가선전압과 판토그래프의 전압차가 일어나고, 그에 따른 방전전류가 흐르게 되고, 이의 형태는 펄스의 형태로 나타나게 된다. If the representation of an equivalent impedance for the voltage, the current that flows through the Pantograph as Z eq, Z eq is composed of an inductance component L eq, the resistance component of R eq, a capacitance component C in eq. When the voltage at the wiring generally hayeoteul that the AC sine wave is applied to 25kv, the case has not occurred yiseonyi has a voltage applied to the Pantograph is 25kv, current flows according to the equivalent impedance Z eq. However, when this line occurs, the voltage applied to the pantograph does not decrease instantaneously due to the capacitance component C eq , but is maintained, but the current drops to zero. In the part where the current has fallen to 0, after a certain time, the voltage difference between the line voltage and the pantograph occurs, and the discharge current flows according to the current, and the shape thereof is expressed in the form of a pulse.

따라서, 전압의 변화 및 전류의 형태로 판단을 하면, 판토그래프와 전차선의 집전상태를 검측할 수 있으며, 전기적인 접촉의 계산을 통해 좀 더 정확한 이선을 파악할 수 있는 것이다. 이런 방전전류의 값은 고조파에 의한 전류보다 훨씬 높은 고주파의 영역이므로, HF(HighPass Filter)를 이용하여 검측이 가능하다.
Therefore, when judging in the form of voltage change and current, it is possible to detect the current collection state of the pantograph and the tramline, and to determine a more accurate two-line through the calculation of the electrical contact. Since the value of this discharge current is a region of high frequency much higher than the current caused by harmonics, detection of the discharge current is possible using a high pass filter (HF).
