전동차용 팬터그래프 승강제어시스템 {Up-Down Control System of Pantograph for Electromotion Vehicle}Pan-graph lift control system for electric vehicles {Up-Down Control System of Pantograph for Electromotion Vehicle}

도 1은 본 발명에 따른 전동차용 팬터그래프 승강제어시스템의 일실시예를 적용한 전동차를 개념적으로 나타내는 측면도이다.1 is a side view conceptually showing an electric vehicle to which an embodiment of the pantograph elevating control system for an electric vehicle according to the present invention is applied.

도 2는 본 발명에 따른 전동차용 팬터그래프 승강제어시스템의 일실시예를 개략적으로 나타내는 회로도이다.2 is a circuit diagram schematically showing an embodiment of a pantograph elevating control system for an electric vehicle according to the present invention.

본 발명은 전동차용 팬터그래프 승강제어시스템에 관한 것으로서, 보다 상세하게는 전동차에 있어서 팬터그래프에서 문제가 발생한 경우 고장여부를 용이하게 판별하여 부동상태로 전환하여 운행하므로 지연시간을 최소화하는 것이 가능한 전동차용 팬터그래프 승강제어시스템에 관한 것이다.The present invention relates to a pantograph elevating control system for an electric vehicle, and more particularly, a pantograph for an electric vehicle capable of minimizing a delay time by easily determining whether a failure occurs in a pantograph and moving to a floating state. It relates to a lift control system.

일반적으로 전동차는 팬터그래프(pantograph)를 통하여 인가되는 전원을 이용하여 구동하는 차량으로, 운전실이 구비되어 있는 선두차가 앞쪽과 뒤쪽에 각각 배치되고, 추진장치가 장착된 동력차와 추진장치가 장착되지 않은 무동력차를 혼합하여 양쪽 선두차 사이에 배치하여 운행된다.In general, an electric vehicle is a vehicle driven by a power applied through a pantograph, and a front vehicle equipped with a cab is disposed at the front and the rear, respectively, a power vehicle equipped with a propulsion device and a non-propulsion device without a propulsion device. The cars are mixed and run between the two leading cars.

상기 동력차에 장착되는 추진장치로는 저항제어시스템, 쵸퍼제어시스템, 인버터제어시스템(VVVF) 등이 사용된다.As a propulsion device mounted on the power vehicle, a resistance control system, a chopper control system, an inverter control system (VVVF), and the like are used.

상기에서 팬터그래프는 동력차의 지붕에 1개이상이 설치되어 전력공급선(일반적으로 트롤리선 또는 트롤리바로 구성)으로부터 전력을 공급받는 장치로, 대략 마름모형상의 링크부재로 이루어지며, 공기압 및 탄성력 등을 이용하여 상승 및 하강하도록 구성된다.In the above, the pantograph is a device in which one or more are installed on the roof of the power vehicle to receive electric power from a power supply line (generally composed of a trolley line or a trolley bar). The pantograph is made of a substantially rhombic link member and uses air pressure and elastic force. To rise and fall.

종래 팬터그래프는 운전자가 팬터그래프 상승스위치(PanUS;Pantograph Up Switch)를 작동시킴에 따라 보조 컴프레서 모터 제어스위치(ACMCS;Auxiliary Compressor Motor Control Switch)가 작동하여 보조 컴프레서 모터(ACM;Auxiliary Compressor Motor)를 구동시키고, 보조 컴프레서 모터가 구동함에 따라 발생하는 공기압에 의하여 상승한다. 또 운전자가 팬터그래프 하강스위치(PanDS;Pantograph Down Switch)를 작동시킴에 따라 공기압이 배기되어 팬터그래프는 하강하게 된다.In the conventional pantograph, an auxiliary compressor motor control switch (ACMCS) is operated as a driver operates a pantograph up switch (PANUS) to drive an auxiliary compressor motor (ACM). As a result, the air pressure rises as the auxiliary compressor motor is driven. In addition, as the driver operates the Pantograph Down Switch (PanDS), the air pressure is exhausted and the pantograph is lowered.

상기에서 팬터그래프 상승스위치를 작동시키면 팬터그래프 제어회로의 팬터그래프 전자밸브(PanV;Pantograph magnet Valve)가 여자되어 공기를 가압시켜 팬터그래프를 상승시키게 되고, 팬터그래프 하강스위치를 작동시키면 팬터그래프 전자밸브가 소자되어 공기압을 배기시켜 팬터그래프를 하강시키게 된다.When the pantograph up switch is operated, the pantograph magnet valve (PanV) of the pantograph control circuit is excited to pressurize the air to raise the pantograph. This will lower the pantograph.

그리고 상기 팬터그래프에는 상승된 상태에서 전력공급선에 접촉된 상태를 일정하게 유지하기 위하여 탄성력을 부여하는 스프링 등이 설치된다.And the pantograph is provided with a spring or the like to give an elastic force to maintain a constant contact with the power supply line in the elevated state.

종래 전동차에 있어서는 선두차의 운전실에서 모든 팬터그래프에 대하여 하나의 스위치로 제어하도록 구성되어 고장이 발생하는 경우 대처에 많은 시간이 소요된다.In the conventional electric vehicle, it is configured to control all pantographs with one switch in the cab of the head car, and therefore, a lot of time is required to cope with a failure.

즉 교류와 직류를 겸용하는 구간이 있는 경우에는 특고압계통의 고장(예를 들면 낙뢰나 직류 모진 등)이 발생하는 빈도가 매우 높으며, 어느 하나의 유니트에서 고장이 발생하는 경우 해당 유니트를 완전부동 상태로 취급하여야 한다. 그러나 승객이 많거나 전동차가 지하구간에 정차한 경우에는 조치시간이 과다하게 소요되며, 400m 정도를 승객 사이를 비집고 통과하여 조치를 행하여야 하는 경우도 발생한다.In other words, if there is a section where both AC and DC are used, the frequency of the special high-voltage system (for example, lightning or direct current high) is very high.In the event of a failure in any one unit, the unit is completely floating. Should be treated as is. However, when there are a lot of passengers or when the electric vehicle stops in the underground section, it takes too much time to take action, and there is a case where the action is to be taken by passing through about 400m between passengers.

종래 전동차에 있어서는 고장이 발생하면, 각 유니트의 분전함에서 개별적으로 팬터그래프의 상승과 하강을 행하면서 사령실과 교신을 행하여 동력의 공급이 이루어지지 않는 팬터그래프(고장 팬터그래프)를 찾아내는 작업을 행하여야 한다. 이 때 운전자는 각 팬터그래프가 설치된 분전함과 운전실을 계속하여 왕복이동하면서 사령실과의 교신을 행하고 팬터그래프의 상승과 하강을 행하여야 하므로, 고장을 찾아내는 데 장시간이 소요된다. 예를 들면 가장 멀리 있는 팬터그래프까지 이동하는 데 소요되는 시간은 대략 10여분이 되며, 각 팬터그래프까지 반복하여 왕복하므로, 고장을 찾아내는 데 1시간여가 소요되는 경우도 발생한다.In a conventional electric vehicle, when a failure occurs, it is necessary to perform a task of finding a pantograph (failed pantograph) in which power is not supplied by communicating with the command room while raising and lowering the pantograph separately in each distribution box of each unit. At this time, the driver must communicate with the command room while continuing to reciprocate the distribution box and the cab with each pantograph installed, and ascend and descend the pantograph, it takes a long time to find a fault. For example, it takes about 10 minutes to move to the farthest pantograph, and it takes about an hour to find a fault since it repeatedly reciprocates to each pantograph.

본 발명의 목적은 상기와 같은 문제점을 해결하기 위한 것으로서, 운전실에 서 팬터그래프를 각각 선택적으로 작동시켜 고장여부를 용이하게 짧은 시간내에 파악하는 것이 가능하고 고장이 발생한 팬터그래프 및 동력차를 완전부동(무작동 또는 무동력) 상태로 조치하여 전동차를 운행하는 것이 가능한 전동차용 팬터그래프 승강제어시스템을 제공하기 위한 것이다.An object of the present invention is to solve the problems described above, by operating the pantographs selectively in the cab, it is possible to easily determine whether the fault within a short time, and to fully float the pantograph and the power car that has failed (no operation) Or it is to provide a pantograph elevating control system for an electric vehicle capable of operating the electric vehicle in a state of no power).

Is installed on.

상기 팬터그래프 상승스위치(PanUS)에 관련된 회로는 일반적인 전동차의 팬터그래프 상승회로를 이용하여 실시하는 것이 가능하므로, 상세한 설명은 생략한다.The circuit related to the pantograph rise switch PanUS can be implemented using a pantograph rise circuit of a general electric vehicle, and thus detailed description thereof will be omitted.

본 발명에 따른 전동차용 팬터그래프 승강제어시스템에 있어서는 팬터그래프 하강스위치(PanDS)에 관련된 제어신호선(22), (24), (26)을 각각의 동력차(M1)에 대응하여 복수로 병렬 배치하고 각각의 제어신호선(22), (24), (26)의 개폐를 행하는 작동스위치(12), (14), (16)를 제어반(10)에 설치하는 것이 특징이 있으므로, 이를 제외한 다른 구성은 일반적인 전동차의 구성을 적용하여 실시하는 것이 가능 하다.In the pantograph elevating control system for an electric vehicle according to the present invention, a plurality of control signal lines 22, 24, and 26 associated with the pantograph lowering switch PanDS are arranged in parallel in correspondence with each of the power vehicles M1, and Since the operation switch 12, 14, 16 for opening / closing the control signal lines 22, 24, and 26 is provided in the control panel 10, other configurations except this are common electric vehicles. It is possible to implement by applying the configuration of.

상기 팬터그래프 제어회로(20)에는 주회로 차단기(MCB;Main Circuit Braker), 팬터그래프 릴레이(PanR;Pantograph Relay), 팬터그래프 전자밸브(PanV;Pantograph magnet Valve) 등이 직렬 및/또는 병렬로 배열되어 설치된다.The pantograph control circuit 20 includes a main circuit breaker (MCB), a pantograph relay (PanR), a pantograph magnet valve (PanV), and the like arranged in series and / or in parallel. .

상기와 같이 구성되는 본 발명에 따른 전동차용 팬터그래프 승강제어시스템의 일실시예를 적용하여 구성한 전동차의 일예를 도 1에 나타낸다.1 shows an example of an electric vehicle constructed by applying an embodiment of the pantograph elevating control system for an electric vehicle according to the present invention configured as described above.

즉 맨 앞쪽과 뒤쪽에는 각각 선두차(TC)가 배치되고, 지붕에 팬터그래프(4)가 설치되는 동력차(M1)와 팬터그래프(4)가 설치되지 않는 보조동력차(M2), 추진장치(도면에 나타내지 않음)가 설치되지 않는 무동력차(T1), (T2)를 조합하여 배치하여 전동차를 구성한다.That is, the front car TC is disposed at the front and the rear, respectively, the power car M1 having the pantograph 4 installed on the roof, the auxiliary power car M2 without the pantograph 4 installed, and the propulsion device (not shown in the drawing). The electric vehicle is constructed by combining the non-powered vehicles T1 and T2, which are not installed.

상기에서 지붕에 팬터그래프(4)가 설치되는 동력차(M1) 및 보조동력차(M2)에는 추진장치와 견인전동기(TM)(도면에 나타내지 않음)가 장착된다. 따라서 동력차(M1) 및 보조동력차(M2)는 팬터그래프(4)를 통하여 전원을 인가받아 상기 추진장치가 구동되고, 전동차를 구동시키는 동력을 발생시킨다.In the above, the propulsion device and the traction motor TM (not shown) are mounted on the power vehicle M1 and the auxiliary power vehicle M2 on which the pantograph 4 is installed on the roof. Accordingly, the power vehicle M1 and the auxiliary power vehicle M2 receive power through the pantograph 4 to drive the propulsion device and generate power for driving the electric vehicle.

상기 무동력차(T1), (T2)는 추진장치가 설치되지 않으므로 상기 동력차(M1), (M2)의 구동력에 의하여 견인되어 이동하게 된다. 또, 도면에 나타내지 않았지만. 무동력차(T2)에는 보조전원장치(SIV)와 공기압축기(CM), 배터리 등이 장착된다.Since the propulsion device is not installed, the non-motor vehicle T1 and T2 are towed and moved by the driving force of the power vehicles M1 and M2. In addition, although not shown in the drawing. The non-powered vehicle T2 is equipped with an auxiliary power supply (SIV), an air compressor (CM), a battery, and the like.

상기 선두차(TC)에는 ATC/ATO 신호장치, 주간제어기, 열차정보장치, 열차무선장치, 방송장치, 보조전원장치(SIV), 공기압축기(CM), 배터리 등이 장착되고, 앞쪽에 배치되는 선두차(TC)에는 통상 운전자가 탑승하여 운전실로 운영되고, 뒤쪽에 배치되는 선두차(TC)에는 차장이 탑승하여 운전자를 보조하게 된다.The head vehicle TC is equipped with an ATC / ATO signal device, a daytime controller, a train information device, a train radio device, a broadcasting device, an auxiliary power supply device (SIV), an air compressor (CM), a battery, and the like, and are disposed in front of the vehicle. In general, a driver rides on the lead car TC and operates as a driver's cab, and a deputy commander rides on the lead car TC disposed behind to assist the driver.

상기 선두차(TC)는 무동력차(T1), (T2)와 마찬가지로 추진장치가 장착되지 않므로 구동력을 발생시키지 못한다.Since the lead vehicle TC is not equipped with a propulsion device like the non-powered vehicles T1 and T2, it does not generate a driving force.

다음으로 상기와 같이 구성되는 본 발명에 따른 전동차용 팬터그래프 승강제어시스템의 작동과정을 설명한다.Next will be described the operation of the pantograph elevating control system for an electric vehicle according to the present invention configured as described above.

먼저 정상적인 전동차의 운행중에는 상기 팬터그래프 하강스위치(PanDS) 및 팬터그래프 상승스위치(PanUS)에 의하여 전체의 팬터그래프(4)에 대한 상승 및 하강을 제어한다.First, during the operation of the normal electric vehicle, the pantograph down switch PanDS and the pantograph up switch PanUS control the rising and falling of the entire pantograph 4.

그리고 전동차의 운행중에 낙뢰나 직류모진 등이 발생하여 동력의 공급이 원활하게 이루어지지 않는 경우(고장이 발생한 경우)에는 운전자는 상기 팬터그래프 하강스위치(PanDS)를 작동시켜 전체 팬터그래프(4)를 하강시킨 다음, 사령실과 교신하여 당해 전동차가 고장인지의 여부를 확인하고, 당해 전동차가 고장이 아닌 경우에는 사령실의 지시에 따라 다시 팬터그래프 상승스위치(PanUS)를 작동시켜 정상적인 운행을 수행한다.In the event that a lightning strike or direct current high occurs during the operation of the electric vehicle and the power is not supplied smoothly (when a failure occurs), the driver operates the pantograph lowering switch (PanDS) to lower the entire pantograph (4). Next, communication with the command room confirms whether or not the electric vehicle is out of order. If the electric car is not in fault, the pantograph up switch (PanUS) is operated again according to the command of the commander to perform normal operation.

상기에서 사령실과의 교신 결과 당해 전동차에서 고장이 발생한 경우에는 전체 팬터그래프(4)를 하강시킨 상태에서, 하나를 제외한 나머지 작동스위치(14), (16)를 온(on)시키고, 팬터그래프 상승스위치(PanUS)를 작동시킨다.When a failure occurs in the electric vehicle as a result of the communication with the command room as described above, all the operation switches 14 and 16 except for one are turned on while the pantograph 4 is lowered, and the pantograph up switch ( PanUS).

상기와 같이 작동스위치(12)는 오프(off)이고 작동스위치(14), (16)는 온(on)인 상태에서 팬터그래프 상승스위치(PanUS)를 작동시키면, 제어신호선(24), (26)에 연결된 2번째 및 3번째 동력차(M1)의 팬터그래프(4)는 하강한 상태가 유지되고, 제어신호선(22)에 연결된 1번째 동력차(M1)의 팬터그래프(4)만 상승하게 된다. 즉 제어신호선(24), (26)에 연결된 2번째 및 3번째 동력차(M1)의 팬터그래프(4)는 작동스위치(14), (16)가 온(on) 상태이므로, 팬터그래프에 대한 하강신호가 입력되어 하강상태를 유지하지만, 1번째 동력차(M1)의 팬터그래프(4)는 하강신호가 오프(off)인 상태이므로 팬터그래프 상승스위치(PanUS)에 연결된 상승신호가 입력되어 상승하게 된다.As described above, when the pantograph rising switch PanUS is operated while the operation switch 12 is off and the operation switches 14 and 16 are on, the control signal lines 24 and 26 are operated. The pantographs 4 of the second and third power vehicles M1 connected to the lowered state are maintained and only the pantographs 4 of the first power vehicle M1 connected to the control signal line 22 are raised. That is, since the operation switches 14 and 16 are on in the pantograph 4 of the second and third power vehicles M1 connected to the control signal lines 24 and 26, the falling signal for the pantograph is Although the input is maintained in the falling state, the pantograph 4 of the first power vehicle M1 has the falling signal turned off, so that the rising signal connected to the pantograph rising switch PanUS is inputted to rise.

상기와 같이 하나의 팬터그래프(4)만 상승한 상태에서 운전자는 사령실과 교신하여 전력이 공급되는 지를 확인하고, 전력이 공급되지 않는 경우에는 1번째 동력차(M1)의 팬터그래프(4)가 고장인 것으로 판별한다. 만약 정상적으로 전력이 공급된다면 1번째 동력차(M1)의 팬터그래프(4)는 정상인 것으로 판별한다.In the state where only one pantograph 4 is raised as described above, the driver communicates with the command room to check whether the electric power is supplied. If the electric power is not supplied, the driver determines that the pantograph 4 of the first power vehicle M1 has failed. do. If power is normally supplied, the pantograph 4 of the first power vehicle M1 is determined to be normal.
