Description

本発明は、電気車制御装置に関する。 The present invention relates to an electric vehicle control device.

従来の電気車制御装置は、架線からパンタグラフを介して供給された交流電力を直流電力に変換するコンバータと、コンバータの交流側両端が充電接触器と接触器を介して、それぞれ２次巻線の両端に接続された変圧器と、この変圧器と前記パンタグラフの間に設けられた高速度遮断器と、コンバータの直流側に接続され直流電力を交流電力に変換するインバータと、このインバータの交流側に接続され前記インバータから供給される交流電力により駆動するモータと、コンバータの直流端子間に接続されたフィルタコンデンサと、コンバータの直流端子の一端に接続された電流検出器と、電流検出器により検出された電流値が所定値以上になった場合に、地絡検知信号を出力する地絡検知手段とを有し、地絡検知手段により地絡検知信号が入力された場合には、高速度遮断器、第１と第２の接触器の少なくともいずれかを開放する制御部とから構成されている。   The conventional electric vehicle control device includes a converter that converts AC power supplied from an overhead line via a pantograph into DC power, and both ends of the AC side of the converter are connected to the secondary winding via a charging contactor and a contactor, respectively. A transformer connected to both ends; a high-speed circuit breaker provided between the transformer and the pantograph; an inverter connected to the DC side of the converter for converting DC power to AC power; and the AC side of the inverter A motor driven by AC power supplied from the inverter, a filter capacitor connected between the DC terminals of the converter, a current detector connected to one end of the DC terminal of the converter, and detected by the current detector Ground fault detection means for outputting a ground fault detection signal when the measured current value exceeds a predetermined value, and the ground fault detection signal is output by the ground fault detection means. If it is force, high-speed circuit breaker, and a first control unit for opening at least one of the first contactor.

このように構成された従来の電気車制御装置は、コンバータの直流端子の一端に電流検出器設けているため、地絡を迅速に検知することが出来、地絡電流が流れ続けるのを防止することが出来た（特許文献１参照）。   Since the conventional electric vehicle control device configured in this way is provided with a current detector at one end of the DC terminal of the converter, it can detect a ground fault quickly and prevent the ground fault current from continuing to flow. (See Patent Document 1).

特開平１１−２３５０３９号公報Japanese Patent Laid-Open No. 11-235039

しかしながら、従来の電気車制御装置において、地絡を検出するための地絡検出手段は、電流検出器からの電流検出値を受け取るためのバッファ（受信部）や、電流検出値を比較するための比較部等が必要になる。バッファや比較部には、基本的に複数の半導体チップが必要になり、部品点数が多くなってしまうので、必然的に故障率が高くなる。   However, in the conventional electric vehicle control device, the ground fault detection means for detecting the ground fault is a buffer (receiver) for receiving the current detection value from the current detector, or for comparing the current detection value. A comparison unit is required. The buffer and the comparison unit basically require a plurality of semiconductor chips, and the number of parts increases, so the failure rate inevitably increases.

鉄道車両において地絡検知手段は、一般的に定期検修が２年に一回と定められているが、上述した電流検出器による地絡検知方式では、故障率が高いため、２年に一回の検修では品質上、不充分な可能性があった。 In a railway vehicle, the ground fault detection means is generally determined to have a periodic inspection once every two years. However, the above-mentioned ground fault detection method using a current detector has a high failure rate, so it is once every two years. There was a possibility of insufficient quality in the inspections of the times.

この課題を解決するために、定期検修の周期を短くするという方法も考えられるが、電気車制御装置の検修を行うためには、車両から機器を取り出し、試験を行う必要があり、大掛かりな作業が必要になるため、場所と人手の問題もあり、実務上難しいという問題があった。 In order to solve this problem, a method of shortening the periodic inspection period is also conceivable. However, in order to inspect the electric vehicle control device, it is necessary to take out the equipment from the vehicle and perform a test. Since it requires a lot of work, there was a problem of location and manpower, which was difficult in practice.

そこで、本発明は、地絡検知手段の検修作業を軽減し、検修周期を短くすることが可能な電気車制御装置を提供することを目的とする。 Therefore, an object of the present invention is to provide an electric vehicle control device capable of reducing the inspection work of the ground fault detection means and shortening the inspection cycle.

上記課題は、架線からパンタグラフを介して供給された交流電力を直流電力に変換するコンバータと、前記コンバータの交流側両端が第１と第２の接触器を介して、それぞれ２次巻線の両端に接続された変圧器と、この変圧器と前記パンタグラフの間に設けられた高速度遮断器と、前記コンバータの直流側に接続され、直流電力を交流電力に変換するインバータと、このインバータの交流側に接続され、前記インバータから供給される交流電力により駆動するモータと、前記コンバータの直流端子間に接続されたフィルタコンデンサと、前記フィルタコンデンサーの中性点に接続された電流検出器と、前記電流検出器により検出された電流値が所定値以上になった場合に、地絡検知信号を出力する地絡検知手段と、前記コンバータと前記インバータの制御を行い、前記地絡検知手段により地絡検知信号が入力された場合には、前記高速度遮断器、第１と第２の接触器の少なくともいずれかを開放する制御部と、前記電流検出器の一次側に設けられ、検修用電流を流すことが可能な検修回路と、所定のタイミングで、前記検修回路を動作させ、前記電流検出器に検修用電流を流すことにより、前記地絡検地手段が正常に動作しているか否かを判別する検修判断手段とを備えたことにより達成することが出来る。   The above problem is that a converter that converts AC power supplied from an overhead wire through a pantograph to DC power, and both ends of the secondary winding are connected to both ends of the secondary winding via first and second contactors, respectively. A transformer connected to the transformer, a high-speed circuit breaker provided between the transformer and the pantograph, an inverter connected to the DC side of the converter and converting DC power to AC power, and an AC of the inverter A motor driven by AC power supplied from the inverter, a filter capacitor connected between DC terminals of the converter, a current detector connected to a neutral point of the filter capacitor, A ground fault detection means for outputting a ground fault detection signal when the current value detected by the current detector exceeds a predetermined value; And when the ground fault detection signal is input by the ground fault detection means, the high speed circuit breaker, a controller that opens at least one of the first and second contactors, A repair circuit provided on the primary side of the current detector and capable of flowing a repair current, and operating the repair circuit at a predetermined timing to pass a repair current to the current detector This can be achieved by providing repair judgment means for judging whether or not the ground fault checking means is operating normally.

本発明により、地絡検知手段の検修作業を軽減し、検修周期を短くすることが可能な電気車制御装置を提供することができる。 According to the present invention, it is possible to provide an electric vehicle control device capable of reducing the repair work of the ground fault detection means and shortening the repair cycle.

（第１の実施の形態）
本発明に基づく第１の実施の形態の電気車制御装置について、図を参照し詳細に説明する。図１は、本発明基づく第１の実施の形態の電気車制御装置の構成図である。 (First embodiment)
An electric vehicle control apparatus according to a first embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a configuration diagram of an electric vehicle control apparatus according to a first embodiment of the present invention.

本発明に基づく第１の実施の形態の電気車制御装置において、パンタグラフ１は、架線から交流電力を授受するために、車両の屋根に設けられている。高速度遮断器２は、電流の遮断を行うために設けられ、その一端がパンタグラフ１と接続され、他端は変圧器３の一次巻線と接続される。変圧器３は、電圧変換を行うために設けられ、２次巻線の両端には、第１の接触器４と第２の接触器５が各々接続されている。コンバータ６は、交流電力を直流電力を変換するために設けられ、第１の接触器５と第２の接触器６を介して、変圧器３の３次巻線に接続されている。コンバータ６の直流側には、直流電力を交流電力を変換するインバータ９が接続されている。コンバータ６の直流端子間には、第１のフィルタコンデンサ７と第２のフィルタコンデンサ８が接続されている。インバータ９の交流側には、モータ１０が接続されている。フィルタコンデンの中性点（第１のフィルタコンデンサ７と第２のフィルタコンデンサ８の間）に、抵抗１２と電流検出器１３とから構成される直列回路の一端が接続され、他端は接地されている。コンデンサ１１は、抵抗１２と電流検出器１３とから構成される直列回路に並列接続されている。電流検出器１３により検出された電流値は、制御部１４に入力される。電流検出器１３の一次側の一端には、抵抗２０、スイッチ２１、バッテリ２２からなる検修回路が接続され、他端は接地されている。   In the electric vehicle control apparatus according to the first embodiment of the present invention, the pantograph 1 is provided on the roof of the vehicle in order to exchange AC power from the overhead line. The high-speed circuit breaker 2 is provided for interrupting current, and one end thereof is connected to the pantograph 1 and the other end is connected to the primary winding of the transformer 3. The transformer 3 is provided for performing voltage conversion, and a first contactor 4 and a second contactor 5 are connected to both ends of the secondary winding. The converter 6 is provided to convert AC power into DC power, and is connected to the tertiary winding of the transformer 3 via the first contactor 5 and the second contactor 6. An inverter 9 for converting DC power to AC power is connected to the DC side of the converter 6. A first filter capacitor 7 and a second filter capacitor 8 are connected between the DC terminals of the converter 6. A motor 10 is connected to the AC side of the inverter 9. One end of a series circuit composed of a resistor 12 and a current detector 13 is connected to the neutral point of the filter capacitor (between the first filter capacitor 7 and the second filter capacitor 8), and the other end is grounded. ing. The capacitor 11 is connected in parallel to a series circuit including a resistor 12 and a current detector 13. The current value detected by the current detector 13 is input to the control unit 14. One end of the primary side of the current detector 13 is connected to a repair circuit including a resistor 20, a switch 21, and a battery 22, and the other end is grounded.

制御部１４は、コンバータ・インバータ制御手段１９と、地絡電流を検知し地絡検知信号を出力する地絡検知手段１５と、高速度遮断器２、接触器４と接触器５の開閉を制御する接触器制御手段１７とから構成されている。   The control unit 14 controls the switching of the converter / inverter control means 19, the ground fault detection means 15 that detects the ground fault current and outputs a ground fault detection signal, the high-speed circuit breaker 2, the contactor 4, and the contactor 5. The contactor control means 17 is configured.

地絡検知手段１５は、図示しないバッファを介して、電流検出器１３と接続された比較器１６と、比較器１６と接続された検修判断手段１８から構成されている。 The ground fault detection means 15 includes a comparator 16 connected to the current detector 13 and a repair determination means 18 connected to the comparator 16 via a buffer (not shown).

このように構成された電気車制御装置において、制御部１４の地絡検知手段１５は、電流検出器１６により検出された電流値を比較し、電流値が所定値以上であった場合には、地絡検知信号を接触器制御手段１７に入力する。接触器制御手段１７は、地絡検知信号が地絡検知手段１５から入力された場合に、接触器４、５を開き、所定時間以上、地絡検知信号が入力された場合には高速度遮断器２を開き電流を遮断させる。コンバータ・インバータ制御手段１９は、コンバータ６、インバータ９の素子のスイッチングを制御することにより、モータ１０に交流電力を供給する。   In the electric vehicle control device configured as described above, the ground fault detection means 15 of the control unit 14 compares the current value detected by the current detector 16, and if the current value is equal to or greater than a predetermined value, A ground fault detection signal is input to the contactor control means 17. The contactor control means 17 opens the contactors 4 and 5 when a ground fault detection signal is input from the ground fault detection means 15, and shuts off at a high speed when the ground fault detection signal is input for a predetermined time or more. Open the device 2 and cut off the current. The converter / inverter control means 19 supplies AC power to the motor 10 by controlling switching of the elements of the converter 6 and the inverter 9.

地絡検知手段１５に入力された電流値は、図示しないバッファを介して、比較器１６に入力され、入力された電流値を比較し、所定値以上であった場合には、地絡検知信号を出力する。地絡検知信号は、検修判断手段１８と接触器制御手段１７とコンバータ・インバータ制御手段１９に入力される。   The current value input to the ground fault detection means 15 is input to the comparator 16 through a buffer (not shown), and the input current value is compared. Is output. The ground fault detection signal is input to the repair determination means 18, the contactor control means 17, and the converter / inverter control means 19.

検修判断手段１８は、第１の接触器４と第２の接触器５が開放されている場合に、スイッチ２１をＯＮして、バッテリ２２から抵抗２０を介して電流検出器１３に、検修電流を流す。各機器が正常であれば、検修用電流が流れると、電流検出器１３により電流値が検出され、比較器１６により地絡検知信号が入力され地絡検知信号が検修判断手段１８に入力される。しかしながら、各機器が正常でない場合には、検修判断手段１８に地絡検知信号が入力されない。そのため、地絡検知手段１５は、所定の条件に基づき、スイッチ２１をＯＮした際に、地絡検知信号が入力されれば、電流検出器１３や地絡検知手段１５が正常とみなし、地絡検知信号が入力されなかった場合には、電流検出器１３や地絡検知手段１５が故障したものとみなし、図示しないモニタに故障信号を出力する。   The repair judgment means 18 turns on the switch 21 when the first contactor 4 and the second contactor 5 are opened, and detects the current from the battery 22 to the current detector 13 via the resistor 20. Apply the repair current. If each device is normal, when a repair current flows, the current value is detected by the current detector 13, the ground fault detection signal is input by the comparator 16, and the ground fault detection signal is input to the repair determination means 18. Is done. However, if each device is not normal, the ground fault detection signal is not input to the repair determination means 18. For this reason, if the ground fault detection signal is input when the switch 21 is turned on based on a predetermined condition, the ground fault detection means 15 regards the current detector 13 and the ground fault detection means 15 as normal, and the ground fault is detected. If no detection signal is input, it is assumed that the current detector 13 or the ground fault detection means 15 has failed, and a failure signal is output to a monitor (not shown).

このように構成された電気車制御装置は、検修回路（２０、２１、２２）を装置内に備えているため電流検出器が正常か否か判断をする場合であっても、電気車制御装置を車両から降ろす必要がない。また、所定のタイミングで、システム側で前記検修回路（２０、２１、２２）を動作させ、前記電流検出器１３に検修用電流を流し、電流検出器１３や地絡検地手段１５が正常に動作しているか否かを判別することができるため、検修周期を短くすることも、実運用上で可能になる。   Since the electric vehicle control device configured as described above includes the repair circuit (20, 21, 22) in the device, the electric vehicle control device can determine whether or not the current detector is normal. There is no need to remove the device from the vehicle. Further, at a predetermined timing, the repair circuit (20, 21, 22) is operated on the system side, a repair current is supplied to the current detector 13, and the current detector 13 and the ground fault checking means 15 are normal. Therefore, it is possible to shorten the inspection period in actual operation.

また、本実施の形態の電気車制御装置において、地絡した場合の電流は抵抗１２を介して地絡電流が流れるため、小電流を流せばよいので大型のバッテリを設ける必要がないので、検修回路（２０、２１、２２）を小型化することが出来、制御部１４への内臓が可能となる。そのため、従来の電気車制御装置への搭載も可能となるというメリットがある。   In addition, in the electric vehicle control apparatus of the present embodiment, since a ground fault current flows through the resistor 12 in the case of a ground fault, it is only necessary to pass a small current, so there is no need to provide a large battery. The repair circuit (20, 21, 22) can be reduced in size, and can be incorporated in the control unit 14. Therefore, there is an advantage that it can be mounted on a conventional electric vehicle control device.

本発明に基づく第２の実施の形態の電気車制御装置は、高速度遮断器２が開いていることを条件に、スイッチ２１をオンして、検修用電流を流す。検修判断手段１８は、検修用電流の電流値が、比較器１６により地絡検知信号が入力された場合には、地絡検知手段１５は正常とみなし、比較器１６により地絡検知信号が入力されなかった場合には、地絡検知手段１５が故障したものとみなし、図示しないモニタに故障信号を出力する。 In the electric vehicle control apparatus according to the second embodiment of the present invention, the switch 21 is turned on and a current for repairing is supplied on condition that the high-speed circuit breaker 2 is open. The repair determination means 18 assumes that the ground fault detection means 15 is normal when the current value of the repair current is input by the comparator 16 and the ground fault detection signal is detected by the comparator 16. Is not input, it is considered that the ground fault detection means 15 has failed, and a failure signal is output to a monitor (not shown).

このように構成された電気車制御装置は、地絡検知手段の検修作業を軽減し、検修周期を短くすることが出来る。 The electric vehicle control device configured as described above can reduce the repair work of the ground fault detection means and shorten the repair cycle.

On condition, the switch 21 is turned on and a current for repairing is made to flow. The repair determination means 18 assumes that the ground fault detection means 15 is normal when the current value of the repair current is input by the comparator 16 and the ground fault detection signal is detected by the comparator 16. Is not input, it is considered that the ground fault detection means 15 has failed, and a failure signal is output to a monitor (not shown).

このように構成された電気車制御装置は、地絡検知手段の検修作業を軽減し、検修周期を短くすることが出来る。 The electric vehicle control device configured as described above can reduce the repair work of the ground fault detection means and shorten the repair cycle.
