본 고안은 철도 차량에 설치된 밧데리의 방전을 방지하는 장치에 관한 것으로, 특히 보조 전원 장치가 기동하지 못하면 BCDR(Battery Charging control Delay Relay)이 여자되어 팬터그래프 계전기를 트립시켜 팬터그래프(Pantograph)를 하강시킴으로서 밧데리의 방전을 방지하도록 된 장치에 관한 것이다.The present invention relates to a device for preventing the discharge of the battery installed in a railroad vehicle, and in particular, if the auxiliary power supply fails to start the battery charging control delay relay (BCDR) is excited to trip the pantograph relay to lower the pantograph (Pantograph) It relates to a device that is to prevent the discharge of.

일반적으로 철차의 운행을 마치고 철도차량의 기지나 역에 철차를 야간 주박시킬 때, 운전자가 철차의 전원을 끄지 않고 이동한 상태에서 가선 정전이 되면 철차에 내장된 밧데리는 방전되기 시작한다.In general, when the train is stationed at the base or station of the railway car at night after the operation of the railway, when the driver moves without turning off the railway, the built-in battery starts to discharge.

가선 정전이 되면 보조 전원 장치의 입력 전원이 없으므로 철차의 모든 AC 전원이 차단되고, 밧데리의 충전 전원이 없는 상태에서 DC 전원은 그대로 사용하고 있는 상황이므로 밧데리의 과방전을 통한 밧데리 소손이 발생한다.In case of power outage, all AC power of the vehicle is cut off because there is no input power of auxiliary power supply device, and DC power is used as it is without battery charging power, and battery burnout occurs due to over discharge of battery.

이와 같이, 종래에는 팬터그래터 상승 상태에서 가선 정전이 되었을 때 밧데리의 방전을 방지하는 회로가 구성되어 있지 않아서 밧데리의 과방전으로 인한 밧데리의 소손이 발생하는 문제점이 있다.As described above, there is a problem in that the burnout of the battery due to the overdischarge of the battery is not generated because a circuit for preventing the discharge of the battery is not configured when the power failure occurs in the pantographer up state.

이에 본 고안은 상기와 같은 종래의 문제점을 해결하기 위해, 가선 정전이 되었을 때 밧데리의 방전을 막도록 된 철차의 밧데리 보호 장치를 제공하는 것을 목적으로 한다.In order to solve the above problems, the present invention aims to provide a battery protection device for an electric vehicle which prevents battery discharge when a wire blackout occurs.

상기와 같은 목적을 달성하기 위한 본 고안의 철차의 밧데리 보호장치는,Battery protection device of the iron vehicle of the present invention for achieving the above object,

보조 전원 장치가 기동하지 못하면 동작하는 BCDR; 상기 BCDR 동작하여 소정의 시간이 지난 후 여자되면 트립(trip)되는 팬터그래프 계전기; 상기 팬터그래프 계전기가 트립되면 소자되는 밧데리 접촉기로 구성되는 것을 특징으로 한다.BCDR operating if the auxiliary power supply fails to start; A pantograph relay which trips when the BCDR is operated and is excited after a predetermined time elapses; The pantograph relay is characterized in that consisting of a battery contactor element that is tripped.

이하, 첨부된 도면을 참조하여 본 고안을 자세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described the present invention in detail.

제1도는 본 고안에 따른 밧데리 보호 회로의 블록도로서, 전원을 공급하는 보조 전원 장치부(10); 상기 보조 전원 장치부(10)가 기동하지 못하면 동작하는 BCDR(11); 상기 BCDR(11)이 동작하여 소정의 시간이 지난 후 여자되면 트립되는 팬터그래프 계전기(12); 상기 팬터그래프 계전기(12)가 트립되면 소자되는 밧데리 접촉기(13); 상기 밧데리 접촉기(13)가 소자되면 DC 전원을 방전하지 못하는 밧데리(14)로 구성된다.1 is a block diagram of a battery protection circuit according to the present invention, an auxiliary power supply unit 10 for supplying power; A BCDR 11 operating when the auxiliary power supply unit 10 fails to start; A pantograph relay 12 which trips when the BCDR 11 operates and is excited after a predetermined time has passed; A battery contactor element 13 which is elementd when the pantograph relay 12 is tripped; If the battery contactor 13 is a device is composed of a battery 14 that can not discharge the DC power.

이어서, 상기와 같이 동작하는 본 고안을 자세히 설명한다.Next, the present invention operating as described above will be described in detail.

철도 차량의 기지나 역에서 철차가 야간 주박할 때, 운전자가 철차의 전원을 끄지 않고 철차를 떠난 후 가선 정전이 되어 상기 보조 전원 장치부(10)가 기동하지 못해 전원을 공급하지 못하면, 상기 BCDR(11)이 동작하여 설정된 소정의 시간이 지난 후 여자된다. 상기 BCDR(11)이 여자되면 상기 팬터그래프 계전기(12)는 트립되며, 상기 팬터그래프 계전기(12)가 트립되면 상승 상태에 있던 팬터그래프는 하강되며, 상기 팬터그래프의 하강에 따라 상기 밧데리 접촉기(13)는 소자되고, 상기 밧데리 접촉기(13)가 소자되면 상기 밧데리(14)는 DC전원을 방전하지 못한다.When the train is cruising at the base or station of a railroad car at night, when the driver leaves the train without turning off the power of the railway, when the auxiliary power supply unit 10 fails to start the power supply due to a power outage, the BCDR (11) is operated and excited after the predetermined time set. When the BCDR 11 is excited, the pantograph relay 12 is tripped, and when the pantograph relay 12 is tripped, the pantograph that is in an up state is lowered, and the battery contactor 13 is in accordance with the descending of the pantograph. When the battery contactor 13 is elementary, the battery 14 does not discharge DC power.

상기와 같이 전원 장치가 전원을 공급하지 못하면 밧데리의 방전을 막는 장치가 설치된 철차에 있어서, 상기 철차에 사고가 발생하여 전원을 끊고 구원 운전할 경우에, 전원이 끊어짐에 따라 밧데리의 방전도 이루어지지 않아 철차내 라이트(light)가 모두 꺼져 운전자 및 승객이 불안하게 되는 문제점이 있으므로 전원을 끊고 운전을 하는 철차에 있어서 다음과 같은 회로를 첨가한다.As described above, in a train equipped with a device that prevents battery discharge when the power supply fails to supply power, when an accident occurs in the train and the power is cut off and saved, the battery is not discharged as the power is cut off. Since there is a problem that the driver and passengers are unstable because all of the lights in the train are turned off, the following circuit is added to the train that is turned off and driven.

제2도는 본 고안에 따른 구원 운전 회로의 블록도로서, 구원 운전시 턴온되는 ES(20); 상기 ES(20)가 턴온되면 여자되는 LCAR(21)로 구성된다.2 is a block diagram of the salvation driving circuit according to the present invention, ES 20 is turned on during the salvage operation; The ES 20 is composed of an LCAR 21 that is excited when turned on.

이어서, 상기와 같이 동작하는 본 고안을 자세히 설명한다.Next, the present invention operating as described above will be described in detail.

사고가 발생하여 철차가 구원 운전 될 때에 운전자가 상기 ES(Emergency Switch)(20)를 누르면, 상기 ES(20)는 턴온되면서 상기 LCAR(Load Control Auxiliary Relay)(21)가 여자된다. 상기 LCAR(21)은 상기 BCDR(11)과 교번적으로 턴온되게 구성되어 있기 때문에 상기 LCAR(21)가 여자되면 상기 BCDR(11)의 여자가 방지되므로 DC 전원이 차단되지 않는다.When the driver presses the Emergency Switch (ES) 20 when an accident occurs and the train is saved, the ES 20 is turned on and the Load Control Auxiliary Relay (LCAR) 21 is excited. Since the LCAR 21 is configured to be alternately turned on with the BCDR 11, when the LCAR 21 is excited, the excitation of the BCDR 11 is prevented, so that DC power is not cut off.

이상에서 설명한 바와 같이 본 고안은, 가선 정전이 되어 밧데리가 방전하면, 밧데리의 방전을 막아 밧데리가 소손되지 않는 효과가 있다.As described above, the present invention has the effect of preventing the battery from being burned out by preventing the battery from being discharged when the battery is discharged due to a wire blackout.
