본 발명은 전기 철도 시스템에 관한 것으로서, 더욱 상세하게는 전기 철도 차량의 검수 및 정비 시 작업자의 안전성을 확보하기 위한 장치 및 시스템에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric railway system, and more particularly, to an apparatus and a system for ensuring the safety of a worker in inspection and maintenance of an electric railway vehicle.

전기 철도란 전기를 동력으로 하여 궤도 위의 차량을 운전하는 철도로서, 고속화 및 대용량화되어, 지하철, 고속 철도와 같이 점점 더 그 적용 범위를 확장하고 있다.Electric railway is a railway that drives a vehicle on an orbit by using electricity as a power source. It is increasing in speed and capacity, expanding its application range such as subway and high-speed railway.

일반적으로, 전기 철도에서는 차량을 차량 기지의 검수고에 입고시킨 후, 검 수자 또는 정비자가 직접 차량 위로 올라가 차량의 상태를 확인하는 방식으로 차량의 검수나 정비를 수행한다. Generally, in an electric railroad, after a vehicle is put in a check base of a vehicle base, a checker or a maintenance person directly ascends the vehicle and performs inspection or maintenance of the vehicle by checking the state of the vehicle.

도 1은 전기 철도 차량이 검수고 내에 입고되어 검수받는 종래의 상태를 도시한 개략적인 도면이다.1 is a schematic view showing a conventional state in which an electric railway vehicle is received and inspected in a check hall.

도 1에 도시된 바와 같이 차량을 검수하기 위해서는 먼저 기관사가 차량을 검수고에 입고 후, 차량 내에서 차량 집전 장치를 하강한다.As shown in FIG. 1, in order to inspect the vehicle, the engineer first puts the vehicle in the inspection gate, and then descends the vehicle current collector in the vehicle.

이어서, 전차선 조작반에서 집전 장치의 상태를 확인 후 단로기(10)를 개방한다. 단로기(disconnecting switch; 10)는 부하 전류를 제거한 후 회로를 격리하도록 하기 위한 장치를 말한다. 보통의 부하 전류는 개폐하지 않고, 송전선이나 변전소 등에서 차단기를 연 무부하 상태에서 주회로의 접속을 변경하기 위해 회로를 개폐한다. 단로기 양측에서 회로가 기계적으로 구분되므로 점검이나 수리 등에 편리하고 차단기와는 달리 극히 적은 전류만 통제하므로 구조가 간단하다.Then, the disconnecting device 10 is opened after confirming the state of the current collecting device in the electric cable control panel. Disconnecting switch 10 refers to a device for isolating a circuit after removing the load current. The circuit is opened or closed in order to change the connection of the main circuit in a no-load state with the circuit breaker in a transmission line or a substation without opening or closing the normal load current. Since the circuits are separated mechanically from both sides of the disconnector, it is convenient for inspection and repair, and the structure is simple because it controls only a very small amount of current unlike a breaker.

마지막으로, 검수고 직원이 차량의 상부를 점검하기 위하여 별도의 접지 장치(12)를 전차선에 걸어 충전 전압을 방전시킨 후, 차량의 검수를 수행한다. Finally, in order to inspect the upper part of the vehicle, the inspection staff hangs a separate grounding device (12) on the electric cable to discharge the charging voltage, and carries out inspection of the vehicle.

이와 같은 전기 철도 차량의 검수 시에 검수고 직원이 전차선 단로기(10)를 개방시키지 않고 접지 장치(11)를 설치하는 경우가 발생할 수 있는데, 이 경우 대전류 지락 사고가 발생하여 급전 차단기(미도시)의 손상이 발생될 뿐 아니라, 검수고 직원이 감전되는 사고가 발생한다.In this case, when the electric railway vehicle is inspected, the inspection staff may install the grounding unit 11 without opening the catenary disconnecting unit 10. In this case, a large-current ground fault occurs and a power supply interrupter (not shown) In addition to the damage caused by the inspection, the staff member is caught in an electric shock.

또한, 전차선 가압 상태에서 검수고 출입을 제한할 수 있는 별도의 장치가 없어서 검수고 직원이 무심코 전동차 상부에 접근하였다가 감전 사고를 당하는 경 우가 종종 발생하고 있다.In addition, there is no separate device that can restrict the entrance and exit of the inspection vessel under the pressure of the electric line, so that the inspection staff often unintentionally approach the upper part of the electric car and get an electric shock accident.

본 발명은 상술한 종래의 문제점을 해결하기 위해 안출된 것으로서, 전기 철도 차량의 검수 시, 검수자의 실수로 인한 대전류 지락 사고를 방지할 수 있는 전차선 단로기, 및 전차선 안전 관리 시스템을 제공하는 것을 목적으로 한다.SUMMARY OF THE INVENTION It is an object of the present invention to provide a catenary line disconnecting unit and a catenary line safety management system that can prevent a large-current ground fault due to a fault of an inspector when inspecting an electric railway vehicle do.

또한, 전차선의 가압시에 검수고의 출입을 제한하여 감전 사고를 방지할 수 있는 전차선 단로기, 및 전차선 안전 관리 시스템을 제공하는 것을 목적으로 한다.It is another object of the present invention to provide a catenary line disconnecting unit and a cable line safety management system that can prevent an electric shock accident by limiting entrance and exit of a checkout gate when a catenary line is pressed.

상기 목적을 달성하기 위해 본 발명에 따른 전차선 단로기는 단로부, 및 접지부를 포함한다. 단로부는 전차선을 개방하여 소정 부분의 전차선을 격리시키고, 접지부는 단로부에 의해 격리된 부분의 전차선을 접지한다.In order to achieve the above object, a catenary disconnecting device according to the present invention includes a disconnecting unit and a grounding unit. The disconnecting part opens the catenary line to isolate a predetermined part of the catenary line, and the grounding part grounds the catenary line of the part isolated by the disconnecting part.

이와 같이, 전차선 단로기가 전차선의 격리와 격리된 전차선의 접지를 동시에 수행함으로써, 전기 철도 차량의 검수 시, 검수자의 실수로 인한 대전류 지락 사고를 방지할 수 있게 된다.In this manner, the catenary disconnecting device simultaneously isolates the catenary line and grounds the isolated catenary line, thereby preventing a large-current grounding accident due to a fault of the inspector when inspecting the electric railway vehicle.

전차선 단로기는 접지부에 의해 소정 부분의 전차선이 접지되는 경우 소정의 안전 장치로 제어 신호를 출력하는 신호 출력부를 더 포함할 수 있다.The catenary disconnecting device may further include a signal output unit for outputting a control signal to a predetermined safety device when a predetermined portion of the catenary is grounded by the grounding unit.

격리된 전차선이 접지되는 경우에 소정의 안전 장치를 작동시킴으로써, 전차선의 가압시에만 검수고의 출입을 허용하여 감전 사고를 방지할 수 있게 된다.By operating the predetermined safety device when the isolated electric wire is grounded, it is possible to prevent the electric accident by allowing the entrance and exit of the inspection object only when the electric wire is pressed.

또한, 본 발명에 따른 전차선 안전 관리 시스템은 전차선을 개방하여 소정 부분의 전차선을 격리시키고, 격리된 부분의 전차선을 접지하는 단로기, 및 단로기에 의해 출력된 신호에 따라 소정의 안전 동작을 수행하는 안전 장치를 포함한다.Also, the present invention provides a system for safety management of a catenary line, comprising: a disconnector for opening a catenary line to isolate a predetermined part of a catenary line, a ground line for an isolated part of the catenary line, and a safety Device.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 설명한다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

도 2는 본 발명에 따른 전차선 단로기의 일 실시예의 개략적인 블록도이다.Figure 2 is a schematic block diagram of an embodiment of a catenary disconnector in accordance with the present invention.

도 2에서 전차선 단로기(100)는 단로부(110), 접지부(120), 및 신호 출력부(130)를 포함하고 있다.2, the catenary disconnecting device 100 includes a disconnecting unit 110, a grounding unit 120, and a signal output unit 130.

단로부(110)는 전차선을 개방하여 소정 부분의 전차선을 격리시킨다. 여기서, 소정 부분의 전차선은 차량의 검수를 위해 격리될 미리 설정된 부분의 전차선을 말한다.The disconnecting unit 110 opens the catenary line to isolate the catenary line of a predetermined portion. Here, the predetermined portion of the catenary line refers to a predetermined portion of the catenary line to be isolated for inspection of the vehicle.

접지부(120)는 단로부(110)에 의해 격리된 부분의 전차선을 접지한다. 접지부(120)가 단로부(110)의 전차선의 격리와 동시에 격리된 전차선의 접지를 수행함으로써 전차선의 충전 전압을 방전시켜, 검수자가 별도로 접지를 수행하지 않아도 되므로, 검수자의 실수로 인한 대전류 지락 사고를 방지할 수 있게 된다.The grounding unit 120 grounds the electric wire of the portion isolated by the disconnecting unit 110. [ Since the grounding unit 120 grounds the isolated catenary line simultaneously with the isolation of the catenary line of the disconnecting unit 110, the charging voltage of the catenary line is discharged, and the inspecting person does not have to separately perform grounding. Therefore, It will prevent accidents.

신호 출력부(130)는 접지부(120)에 의해 소정 부분의 전차선이 접지되는 경우 소정의 안전 장치로 제어 신호를 출력한다. 여기서 소정의 안전 장치는 검수고 출입문의 잠금 장치나, 경보기, 디스플레이 화면을 비롯한 검수자가 검수고로 진입하는 것을 막을 수 있는 어떠한 장치로도 구현될 수 있다.The signal output unit 130 outputs a control signal to a predetermined safety device when the grounding unit 120 grounds a predetermined portion of the catenary. Here, the predetermined safeguarding device may be implemented by any device capable of preventing the inspectors including the locking device of the inspection entrance door, the alarm device, the display screen, and the like from entering the inspection hall.

안전 장치가 검수고 출입문 잠금 장치인 경우, 제어 신호는 잠금 장치의 해제 신호일 수 있고, 경보기인 경우 진입 가능 경보 발생 신호일 수 있으며, 디스플레이 화면인 경우에는 진입 가능 화면의 출력 신호일 수 있을 것이다.If the safety device is a checkout door lock device, the control signal may be a release signal of the lock device, an alarm signal for entering the alarm for the alarm, or an output signal for the entryable screen for the display screen.

격리된 전차선이 접지되는 경우에 소정의 안전 장치를 작동시킴으로써, 전차선의 가압시에만 검수고의 출입을 허용하여 작업자의 감전 사고를 방지할 수 있게 된다.By operating a predetermined safety device when the isolated electric wire is grounded, it is possible to prevent the electric shock of the worker by permitting the entrance and exit of the inspection wire only when the electric wire is pressed.

도 3은 본 발명에 따른 전차선 안전 관리 시스템의 일 실시예의 사용 상태를 개략적으로 도시한 도면이다.FIG. 3 is a view schematically showing a usage state of a catenary safety management system according to an embodiment of the present invention.

도 3에서 전차선 안전 관리 시스템(200)은 단로기(210), 및 안전 장치(220)를 포함한다. 단로기(210)는 다시, 단로부(212), 접지부(214), 및 신호 출력부(216)를 포함하며, 안전 장치(220)는 신호 수신부(212), 및 동작 수행부(214)를 포함하고 있다. In FIG. 3, the catenary safety management system 200 includes a disconnector 210, and a safety device 220. The isolator 210 further includes a disconnecting unit 212, a grounding unit 214 and a signal output unit 216.

단로부(212)는 전차선을 개방하여 소정 부분의 전차선을 격리시킨다. 소정 부분의 전차선은 차량의 검수를 위해 격리될 미리 설정된 부분의 전차선인 것은 이미 언급한 바와 같다.The disconnecting unit 212 opens the catenary line to isolate the catenary line of a predetermined portion. It is already mentioned that the predetermined part of the catenary is a predetermined part of the catenary to be isolated for inspection of the vehicle.

접지부(214)는 단로부(212)에 의해 격리된 부분의 전차선을 접지한다. 접지부(214)가 단로부(212)의 전차선의 격리와 동시에 격리된 전차선의 접지를 수행함으로써 전차선의 충전 전압을 방전시켜, 검수자가 별도로 접지를 수행하지 않아도 되므로, 검수자의 실수로 인한 대전류 지락 사고를 방지할 수 있게 된다.The grounding part 214 grounds the electric wire of the part isolated by the disconnecting part 212. [ Since the grounding unit 214 grounds the isolated catenary line simultaneously with the isolation of the catenary line of the disconnecting unit 212, the charging voltage of the catenary line is discharged, and the inspecting person does not have to separately perform grounding. Therefore, It will prevent accidents.

도 3에서 소정의 안전 장치(220)는 검수고 출입문의 잠금 장치로 구현되어 있으나, 안전 장치(220)는 경보기, 디스플레이 화면을 비롯한 검수자가 검수고로 진입하는 것을 막을 수 있는 어떠한 장치로도 구현될 수 있다.In FIG. 3, the predetermined safety device 220 is implemented as a locking device for the inspection entrance door. However, the safety device 220 may be implemented as any device capable of preventing the inspector, including the alarm screen and the display screen, .

신호 수신부(222)는 신호 출력부(216)로부터 전송된 제어 신호를 수신하고, 동작 수행부(214)는 신호 수신부(222)가 수신한 제어 신호에 따라 소정의 안전 동작을 수행한다.The signal receiving unit 222 receives the control signal transmitted from the signal output unit 216 and the operation performing unit 214 performs a predetermined safety operation according to the control signal received by the signal receiving unit 222.

도 3에서 신호 출력부(216)과 신호 수신부(222)는 무선으로 통신하도록 구현되었지만, 유선으로 통신하도록 구현될 수도 있음은 자명할 것이다. In FIG. 3, the signal output unit 216 and the signal receiving unit 222 are implemented to communicate wirelessly, but it will be apparent that they may be implemented to communicate by wire.

소정의 안전 동작은 안전 장치(220)가 검수고 출입문 잠금 장치인 경우, 제어 신호는 잠금 장치의 해제 신호일 수 있고, 경보기인 경우 진입 가능 경보 발생 신호일 수 있으며, 디스플레이 화면인 경우에는 진입 가능 화면의 출력 신호일 수 있다.If the safety device 220 is a security door lock device, the control signal may be a release signal of the lock device, the alarm signal may be an enterable alarm signal, and in the case of a display screen, Output signal.

이와 같이, 격리된 전차선이 접지되는 경우에 소정의 안전 장치를 작동시킴으로써, 전차선의 가압시에만 검수고의 출입을 허용하여 작업자의 감전 사고를 방지할 수 있게 된다.In this way, when the isolated electric wire is grounded, by operating a predetermined safety device, it is possible to prevent the electric shock of the worker by allowing the entrance and exit of the inspection tool only when the electric wire is pressed.

본 발명에 의하면, 전차선 단로기가 전차선의 격리와 격리된 전차선의 접지를 동시에 수행함으로써, 전기 철도 차량의 검수 시 검수자의 실수로 인한 대전류 지락 사고를 방지할 수 있게 된다.According to the present invention, since the catenary disconnecting device simultaneously isolates the catenary line and grounds the isolated catenary line, it is possible to prevent a large current grounding accident due to a mistake of the inspector in the inspection of the electric railway car.

또한, 격리된 전차선이 접지되는 경우에 소정의 안전 장치를 작동시킴으로써, 전차선의 가압시에만 검수고의 출입을 허용하여 작업자의 감전 사고를 방지할 수 있게 된다.In addition, by operating a predetermined safety device when the isolated electric wire is grounded, it is possible to prevent the electric shock of the worker by allowing the entrance and exit of the inspection device only when the electric wire is pressed.
