The charging current is discharged.

상기 감시카메라(3)는 상기 수배전반 내부의 이상유무를 감시하는 것으로서, 상기 감시카메라(3)에서 입력되는 데이터가 제어기(7)를 통하여 외부로 전달되는 것이 바람직하다.The surveillance camera 3 monitors the presence or absence of an abnormality in the switchboard, and the data input from the surveillance camera 3 is preferably transmitted to the outside through the controller 7.

상기 소화전(4)에는 압축 가스에 의해 분출될 수 있는 소화재가 내장되어 있으며, 상기 소화전(4)은 상기 수배전반의 내부에 발생된 화재를 진화하게 된다.The fire hydrant 4 has a built-in fire extinguishing material that can be ejected by the compressed gas, the fire hydrant 4 is to extinguish the fire generated inside the switchgear.

상기 도어록(6)은 전기적인 신호에 의해 상기 수배전반의 도어(11)를 록킹 또는 비록킹하는 것인 바, 상기 제어기(7)에서 출력되는 신호에 의해 작동되어 도어(11)를 록킹 또는 비록킹하게 된다.The door lock 6 locks or even locks the door 11 of the switchboard by an electrical signal, and is operated by a signal output from the controller 7 to lock or even lock the door 11. Done.

상기 제어기(7)는 상기 주차단기(1)와 접지스위치(2), 감시카메라(3), 소화전(4), 화재감지센서(5), 도어록(6)과 연결되어 상기 주차단기(1)와 접지스위치(2), 감시카메라(3), 화재감지센서(5)의 신호를 받아서 외부로 신호를 송출함과 아울러 상기 주차단기(1)와 접지스위치(2), 소화전(4), 도어록(6)을 제어하게 된다.The controller 7 is connected to the parking interrupter 1, the grounding switch 2, the monitoring camera 3, the fire hydrant (4), the fire detection sensor (5), the door lock (6) and the parking interrupter (1) And a signal from the ground switch (2), the surveillance camera (3), and the fire detection sensor (5) to send a signal to the outside, and the parking short (1), ground switch (2), fire hydrant (4), door lock (6) will be controlled.

즉 상기 제어기(7)는 상기 주차단기(1)의 오프 및 테스트위치 상태에서 접지스위치(2)를 온하고, 접지스위치(2)를 통하여 수배전반 내부의 충전 전류가 모두 방전되는 것을 산출한 뒤에 도어록(6)을 오프 상태로 작동시켜서 도어(11)를 개방 가능하게 하며, 상기 감시카메라(3)에서 출력되는 신호를 받아서 외부에 연결된 관리자의 디스플레이(미도시)로 수배전반 내부 상태를 확인하게 하며, 화재감지센서(5)의 신호를 받아서 소화전(4)을 개방하여 수배전반 내부에서 발생된 불을 진화 및 외부로 경보신호를 보내도록 하는 것이다.That is, the controller 7 turns on the ground switch 2 in the off and test position state of the parking terminal 1, and calculates that all the charging current in the switchboard is discharged through the ground switch 2, and then the door lock. Operate (6) in the off state to open the door 11, and receives the signal output from the surveillance camera (3) to check the internal state of the switchboard with a display (not shown) of the manager connected to the outside, Fire hydrant (4) is opened by receiving a signal from the fire sensor (5) to extinguish the fire generated inside the switchgear and send an alarm signal to the outside.

따라서 상기 제어기(7)에는 도 3에 도시한 바와 같이, 유선(또는 무선)으로 통신하는 유(무)선통신기가 구비됨이 바람직하다.Therefore, as shown in FIG. 3, the controller 7 preferably includes a wired (wireless) communication device that communicates by wire (or wireless).

더우기 상기 감시카메라(3)에는 상기 수배전반의 내부를 밝히는 조명등이 구비되어 있는 것이 바람직하다.Furthermore, it is preferable that the surveillance camera 3 is provided with a lamp that illuminates the interior of the switchboard.

이와 같이 이루어지는 본 발명에 의한 안전장치가 구비된 수배전반을 제어하는 방법은 다음과 같다.The method for controlling a switchgear equipped with a safety device according to the present invention made as described above is as follows.

우선 주차단기차단단계(S10)에서는 주차단기(1) 차단 후에 접지스위치(2)를 온(ON)하여 수배전반 내의 충전 전류를 방전하게 된다.First, in the parking short-circuit blocking step (S10), after the parking short-circuit 1 is blocked, the ground switch 2 is turned on to discharge the charging current in the switchboard.

즉 일 예로 도시된 도 1과 도 4와 같이, 주차단기(1)가 작업자가 수동으로 차단하거나 제어기(7)의 신호에 의해 차단될 때, 상기 제어기(7)가 주차단기(1)의 오프 상태 및 테스트 위치를 감지하면 접지스위치(2)에 신호를 보내서 인터록을 해제한 후 접지스위치(2)를 온(ON)하여 수배전반 내부의 충전 전류를 지면 등을 통하여 방전하게 된다. 그리고 본 발명의 화재진화단계(S20)에서는 수배전반 내부의 화재 감지시에 소화전(4)을 작동하여 수배전반 내부를 진화함과 동시에 경보 신호를 출력하고, 상기 주차단기차단단계(S10)로 진행시킨다.That is, as shown in FIGS. 1 and 4 shown as an example, when the parking breaker 1 is manually blocked by the operator or blocked by the signal of the controller 7, the controller 7 is turned off of the parking breaker 1. When the state and test position is detected, the ground switch 2 is signaled to release the interlock, and then the ground switch 2 is turned on to discharge the charging current inside the switchboard through the ground. And fire extinguishing step (S20) of the present invention operates the fire hydrant (4) when detecting the fire inside the switchgear and extinguish the inside of the switchgear and at the same time outputs an alarm signal, and proceeds to the parking short cut step (S10).

즉 도 2와 도 4에 도시한 바와 같이, 수배전반 내부에 화재가 발생되면 화재감지센서(5)에서 급격한 온도 상승 등을 감지하여 제어기(7)에 신호를 출력하면 제어기(7)에서 화재감지센서(5)로부터의 신호를 분석하여 수배전반 내부의 화재임을 판단하여 소화전(4)을 작동하고 경보신호를 출력하여 외부의 관리자에게 알리도록 하고, 주차단기(1)에 신호를 보내서 주차단기(1)를 오프(OFF) 상태로 변환시킨다. That is, as shown in Figures 2 and 4, when a fire occurs in the switchboard, the fire sensor 5 detects a sudden temperature rise and outputs a signal to the controller 7, the fire sensor 7 (5) analyzes the signal from the switchboard to determine the fire inside the switchboard to operate the fire hydrant (4) to output an alarm signal to inform the outside manager, and send a signal to the parking short (1) parking short (1) To the OFF state.

한편 본 발명에서는 수배전반 내부에 잔류된 충전 전류를 방전하기 전에 도어(11)를 개방하지 못하도록 함으로써 작업자가 전기로부터 안전하게 하는 것인 바, 도어록 작동단계(S30)에서는 상기 주차단기차단단계(S10)에서 수배전반 내의 충전 전류의 방전이 완료될 때에 도어록(6)을 비록킹 상태로 가변시킨다.On the other hand, in the present invention, by preventing the operator from opening the door 11 before discharging the charging current remaining in the switchgear bar, the worker is safe from electricity. In the door lock operation step (S30), the parking breaker blocking step (S10). When the discharge of the charging current in the switchgear is completed, the door lock 6 is changed to the locked state.

즉 작업자가 수배전반 내부를 점검 및 수리할 때에 수동으로 주차단기(1)를 차단하거나, 계통에서의 사고가 발생하거나 수배전반 내부의 화재 발생시 주차단기(1)가 차단되면 제어기(7)가 주차단기(1)의 오프 상태를 판단하여 접지스위치(2)를 온(ON)할 수 있도록 하여 수배전반 내의 충전 전류를 방전하게 된다.That is, when the operator inspects and repairs the interior of the switchboard, the parking unit 1 is manually shut off, or when the accident occurs in the system or the fire inside the switchboard, the parking unit 1 is blocked. By determining the OFF state of 1), the ground switch 2 can be turned ON to discharge the charging current in the switchgear.

그리고 접지스위치(2)를 통하여 충전 전류가 방전되면 제어기(7)가 충전 전류의 완전 방전 상태를 판단한 뒤에 도어록(6)을 오프하게 된다.When the charging current is discharged through the ground switch 2, the controller 7 determines the complete discharge state of the charging current and then turns off the door lock 6.

또한 전력이 공급되고 있는 충전상태에서 도어를 개방하고자 하면 도어에 설치된 출입자의 인식신호 장치에 의하여 출입자 관련정보를 수신 받아 개방할 수 있도록 하고 출입자 데이터를 관리하도록 한다.In addition, when the door is to be opened while the power is being supplied, the accessor information is received and opened by the recognition signal device of the accessor installed in the door, and the accessor data is managed.

이렇게 본 발명에서는 수배전반 내부에 작업자 또는 그 외의 사람이 접근하는 상태가 발생되면 아무나 도어를 개방 및 출입할 수 없도록 함으로써 작업자 등의 안전 사고를 미연에 방지할 수 있는 것이며, 수배전반 내부를 상시 감시하여 수배전반 내부의 사고를 예측하고 미리 예방할 수 있도록 하는 수배전반 내부감시단계(S40)에서 수배전반 내부를 상시 감시할 수 있도록 함으로써 수배전반 내부의 사고를 예측하고 미리 예방할 수 있도록 하는 것이다.Thus, in the present invention, when a worker or other people approach the inside of the switchgear, no one can open and enter the door, thereby preventing safety accidents such as a worker, and constantly monitoring the inside of the switchgear. By internally monitoring the switchboard in order to predict and prevent the internal accident in advance (S40) to monitor the inside of the switchboard at all times to predict and prevent accidents inside the switchboard.
