상기와 같은 설비에는 절연가스(SF6)가 충진되는데, 이러한 절연가스(SF6)가 외부로 새어 나올 경우 절연성능이 저하되어 폭발과 같은 심각한 문제를 야기할 수 있으며, 또한, 설비의 운용이 외부전원을 별도로 공급받아야 하기 때문에 전력소모에 따른 비용이 증가하게 되는 문제가 있다.The facility as described above is filled with insulating gas (SF6), and when this insulating gas (SF6) leaks out, the insulation performance is deteriorated, which can cause serious problems such as explosion. Since it must be supplied separately, there is a problem in that the cost according to power consumption increases.

도 2 내지 도 4를 참조하여 본 발명에 따른 전차선 전력공급을 위한 25Kv용 전력공급장치의 작용효과를 설명하면 다음과 같다.Referring to FIGS. 2 to 4, the effect of the 25Kv power supply device for catenary power supply according to the present invention will be described.

도 3을 참조하면, 일 예로, 제1외함(110)에 충진되어 있던 절연가스(SF6)가 연결부위를 통해 서서히 유출될 경우 제1외함(110)의 내압은 유출되는 절연가스(SF6)로 인해 압력강하가 일어나게 되는데, 이를 제1외함(110)의 내부에 설치된 제1압력센서(PS1)가 감지하여 제어부(1000)로 출력하게 되고, 제어부(1000)는 제1압력센서(PS1)로부터 압력값을 전달받아 기설정된 값과 상호 비교하게 되며, 만약 기설정된 값을 초과했다고 판단할 경우 제어부(1000)는 즉시 제1전자밸브(EV1)를 개방하면서 송신기(1100)를 동작제어하여 비상신호(현재 압력값)를 관리자가 상주하고 있는 중앙통제실로 출력하게 된다.Referring to FIG. 3 , for example, when the insulating gas SF6 filled in the first enclosure 110 flows out slowly through the connection portion, the internal pressure of the first enclosure 110 is reduced to the outflowing insulating gas SF6. As a result, a pressure drop occurs, which is detected by the first pressure sensor PS1 installed inside the first enclosure 110 and output to the control unit 1000, and the control unit 1000 receives the output from the first pressure sensor PS1. The pressure value is received and compared with a preset value, and if it is determined that the preset value is exceeded, the controller 1000 immediately opens the first solenoid valve EV1 and controls the transmitter 1100 to signal an emergency. (current pressure value) is output to the central control room where the manager resides.

상기 제1전자밸브(EV1)가 개방됨에 따라 제1변류기외함(210)의 내부에 충진된 절연가스(SF6)는 제1전자밸브(EV1)를 통해 제1외함(110)으로 유입되며, 이에 따라 절연성능이 떨어지는 문제를 해소할 수 있게 된다.As the first solenoid valve EV1 is opened, the insulating gas SF6 filled in the first current transformer enclosure 210 flows into the first enclosure 110 through the first solenoid valve EV1. Accordingly, the problem of poor insulation performance can be solved.

또한, 상기 송신기(1100)를 통해 비상신호(현재 압력 값)를 전달받은 관리자는 즉시 현장으로 출동하여 현재상태를 점검하게 된다.In addition, the manager who receives the emergency signal (current pressure value) through the transmitter 1100 immediately dispatches to the site and checks the current state.

한편, 상기 제어부(1000)는 제1외함(110)의 내압이 안전한 상태에 있다고 판단되면, 즉시 제1전자밸브(EV1)를 폐쇄하여 제1변류기외함(210)으로부터의 절연가스(SF6)에 유출을 차단하게 된다.Meanwhile, when it is determined that the internal pressure of the first enclosure 110 is in a safe state, the control unit 1000 immediately closes the first solenoid valve EV1 to allow the insulation gas SF6 from the first current transformer enclosure 210 to pass through. block outflow.

한편, 상기 제1변류기외함(210)으로부터 절연가스(SF6)를 공급받았음에도 불구하고 제1외함(110)의 내압이 계속 떨어지는 경우, 관리자는 본 발명에 따른 전력공급장치의 동작을 잠시 멈추고 해당 부분을 수리한 다음 절연가스(SF6)를 제1외함(110)으로 주입한다.On the other hand, if the internal pressure of the first enclosure 110 continues to drop even though the insulating gas (SF6) is supplied from the first current transformer enclosure 210, the manager temporarily stops the operation of the power supply device according to the present invention and After repairing the part, an insulating gas (SF6) is injected into the first enclosure (110).

이때, 상기 제1외함(110)으로 주입된 절연가스(SF6)는 제1체크밸브(CV1)를 통해 제1변류기외함(210)의 내부로 유입되면서 제1변류기외함(210)의 내부를 채우게 되며, 제1외함(110)의 내부를 절연가스(SF6)로 충분히 채웠을 때, 제1외함(110)과 제1변류기외함(210)의 내압은 동일한 내압상태를 유지하게 된다.At this time, the insulating gas SF6 injected into the first enclosure 110 flows into the inside of the first current transformer enclosure 210 through the first check valve CV1 and fills the inside of the first current transformer enclosure 210. When the inside of the first enclosure 110 is sufficiently filled with the insulating gas (SF6), the internal pressure of the first enclosure 110 and the first current transformer enclosure 210 maintain the same internal pressure state.

따라서, 상기 제1외함(110)의 내압상태(내압값)만으로 제1변류기외함(210)의 내압상태(내압값)를 측정해 보지 않고도 충분히 유추 가능하기 때문에 시설물관리의 편의성을 개선할 수 있게 된다.Therefore, since the internal pressure state (voltage value) of the first current transformer enclosure 210 can be sufficiently inferred without measuring the internal pressure state (voltage value) of the first enclosure 110, the convenience of facility management can be improved. do.

또한, 상기와 같은 방식으로 다른 외함들(310,510)도 제1·2변류기외함(210,410)를 통해 보충할 수 있어 운용측면에서 매우 편리해지는 이점이 있다.In addition, since the other enclosures 310 and 510 can be supplemented through the first and second current transformer enclosures 210 and 410 in the same manner as described above, there is an advantage in that it is very convenient in terms of operation.

한편, 상기 제1·2변류기(200,400)는 송전된 전력을 변류하는 과정에 열이 발생하게 되고, 이렇게 발생된 열은 내부에 절연가스(SF6)를 데워 팽창시키게 되며, 여기에 더하여 주변온도까지 더해질 경우 절연가스(SF6)의 팽창으로 인한 압력이 증가하게 되면서 절연성능이 저하되는 문제가 있을 수 있다.On the other hand, the first and second current transformers (200, 400) generate heat in the process of transforming the transmitted power, and the heat generated in this way heats and expands the insulating gas (SF6) inside, in addition to this, up to the ambient temperature. When added, the pressure due to the expansion of the insulating gas (SF6) increases, and there may be a problem of deteriorating insulation performance.

이에 본 실시 예에서는 제1·2변류기(200,400)를 온도를 감지 및 냉각할 수 있도록 제1·2온도센서(TS1,TS2)와 수냉각장치(900)를 마련하여 상기와 같은 문제를 해소하였다.Accordingly, in this embodiment, the first and second temperature sensors TS1 and TS2 and the water cooling device 900 are provided to sense and cool the temperature of the first and second current transformers 200 and 400, thereby solving the above problems. .

상기 제1·2온도센서(TS1,TS2)는 통상의 온도측정센서로, 본 실시 예의 경우 제1·2변류기(200,400)의 제1·2변류기외함(210,410)에 각각 설치되어 표면온도를 측정해 이를 제어부(1000)로 출력하는 역할을 한다.The first and second temperature sensors TS1 and TS2 are normal temperature measuring sensors, and in this embodiment are installed in the first and second current transformer enclosures 210 and 410 of the first and second current transformers 200 and 400, respectively, to measure the surface temperature. It serves to output the solution to the controller 1000.

상기 수냉각장치(900)는 수조(910)와 펌프(920) 및 분사관(930)으로 구성되며, 펌프(920) 및 분사관(930)은 배관을 통해 상호 연결된다.The water cooling device 900 is composed of a water tank 910, a pump 920, and a spray pipe 930, and the pump 920 and the spray pipe 930 are interconnected through pipes.

상기 수조(910)는 냉각수가 저장되고, 회수된 냉각수가 저장되는 통으로, 본 실시 예의 경우 제1·2변류기(200,400)와 동축상에 배열되도록 바닥에 설치된다. 이러한 수조(910)는 상부가 개방된 형태이며, 제1·2변류기(200,400)를 거치 냉각수의 낙수를 용이하게 받을 수 있게 상단부는 하부에 비해 상대적으로 넓은 형태를 이루고 있다.The water tank 910 is a container in which cooling water is stored and recovered cooling water is stored, and is installed on the floor so as to be arranged coaxially with the first and second current transformers 200 and 400 in the present embodiment. The water tank 910 has an open upper part, and the upper part has a relatively wider shape than the lower part so that the cooling water can be easily received through the first and second deflectors 200 and 400.

상기 펌프(920)는 제어부(1000)에 의해 동작제어되어 수조(910)의 냉각수를 분사관(930)까지 압송해주는 역할을 한다.The pump 920 is controlled by the control unit 1000 to pump the cooling water in the water tank 910 to the injection pipe 930.

상기 분사관(930)은 다수의 구멍이 형성된 배관으로, 본 실시 예의 경우 제1·2변류기(200,400)의 상부에 각각 배치되어 펌프(920)를 통해 냉각수를 공급받아 제1·2변류기(200,400)로 분사해 냉각하는 역할을 한다.The injection pipe 930 is a pipe formed with a plurality of holes, and in the case of the present embodiment, it is disposed above the first and second current transformers 200 and 400, respectively, and receives cooling water through the pump 920, and the first and second current transformers 200 and 400 ) to play a cooling role.

도 5를 참조하면, 일 예로, 상기 제1·2변류기(200,400)의 작동으로 인해 제1·2변류기외함(210,410)을 통해 발열이 일어나게 되면, 이를 제1·2온도센서(TS1,TS2)가 각각 감지(측정)하여 제어부(1000)로 출력하게 되고, 제어부(1000)는 기설정된 값과 상호 비교하여 기준값을 초과했다고 판단되면 즉시 펌프(920)를 동작제어하게 된다.Referring to FIG. 5, for example, when heat is generated through the first and second current transformer enclosures 210 and 410 due to the operation of the first and second current transformers 200 and 400, this is transmitted to the first and second temperature sensors TS1 and TS2. Each is sensed (measured) and outputted to the control unit 1000, and the control unit 1000 immediately controls the operation of the pump 920 when it is determined that the reference value is exceeded by mutual comparison with a preset value.

상기 펌프(920)의 동작으로 인해 수조(910) 내부에 냉각수는 압송되어 분사관(930)으로 전달되고, 분사관(930)으로 전달된 냉각수는 분사관(930)을 통해 분사되어 제1·2변류기외함(210,410)을 냉각시켜 주게 되며, 이때 제1·2변류기외함(210,410)을 거쳐 낙수되는 냉각수는 수조(910)에 떨어져 저장된다.Due to the operation of the pump 920, the cooling water is pumped inside the water tank 910 and delivered to the injection pipe 930, and the cooling water delivered to the injection pipe 930 is injected through the injection pipe 930 and The two current transformer enclosures 210 and 410 are cooled, and at this time, the cooling water falling through the first and second current transformer enclosures 210 and 410 falls into the water tank 910 and is stored.

이와 같이, 상기 제1·2변류기(200,400)의 작동으로 인해 열이 발생하더라도 수냉각장치(900)가 제1·2변류기외함(210,410)을 신속하게 냉각시켜 줌에 따라 제1·2변류기(200,400) 내부에 절연가스(SF6)가 열로 인해 팽창되어 압력이 증가되는 문제를 해소할 수 있으며, 이에 따라 절연성능이 저하되는 문제를 해소할 수 있는 이점이 있다.As such, even if heat is generated due to the operation of the first and second current transformers 200 and 400, the water cooling device 900 quickly cools the first and second current transformer enclosures 210 and 410, so that the first and second current transformers ( 200,400), it is possible to solve the problem of the pressure being increased due to the expansion of the insulating gas (SF6) inside due to heat, and thus, there is an advantage in that the problem of the insulation performance being lowered can be solved.
