이와같이 구성한 본원발명은 도 1의 왼쪽 입력단은 전원공급(예를들어 한전측 전원 입력단(R,S,T))을 하고, 오른쪽 출력단(U,V,W)은 부하와 연결한다. 이 상태에서 부하측이 쇼트가 되면 단로기 기능의 휴즈(TB1,TB2, TB3)가 내장되어 있어 해당되는 상의 선로를 차단하여 전원공급 입력단을 보호한다.In the present invention configured as described above, the left input terminal of FIG. 1 supplies power (for example, KEPCO's power input terminals R, S, and T), and the right output terminals U, V, and W are connected to a load. In this state, when the load side becomes short, fuses (TB1, TB2, TB3) with disconnector function are built in to protect the power supply input terminal by cutting off the corresponding phase line.

경년 열화에 대해서 열폭주 기능으로 발화, 발열으로 인한 화재로부터 보호하도록, 발열시에는 발열시 녹아내리는 납땜(23)을 서지보호기(20)에 포함시켜, 납땜(23)이 녹아내리면 도 2 및 도 4 에 보인 서지보호기(20)의 티형해머(28)를 지탱하던 절곡단자(25)와 바리스터기판(22) 사이의 스토퍼가 없어지게 되어 스프링(27)의 탄성 복원력과 힌지축(26)을 중심으로 반시계 방향으로 회전하여 티형해머(28)가 이중접점스위치(29)의 접점을 반대로 작동시킨다. 이는 이중접점스위치(29)중 제 1스위치(SW1)는 도 5 와 같이 점등엘이디(61)를 점등시켜 서지보호기가 작동한 것임을 확인 토록 하고, 동시에 도 5 와 같이 전원 입력단과 분리된 제 2스위치(SW2)는 작동(턴 온) 사실을 엠시유(66)가 입력포트(I1,I2)를 통하여 확인토록 하고, 엠시유(66)는 출력포트(O1,O2)를 구동하여 대응 릴레이(65)를 자화시켜 내부접점이 온되고, 이를 엠시유(66)는 입력포트(I3,I4)에서 릴레이 작동으로 인식하여 통신포트(도시하지 않음)를 통한 전원선통신라인(송출라인)으로 선로발화와 같은 이상 상태를 외부 상위 전력 계통 체계에 유접점 신호로 통신(예를들어 RS-485 통신)하여 서지보호 장치 기능 상실 신호를 지속적으로 전송하고 이는 전원 입력단과 계통에서 분리되었기 때문이다. 본 발명은 또한 외부 상위 전력 계통 체계에 유접점 신호로 통신(예를들어 RS-485 통신) 하면 삽입(0.2dB이하),반사(20dB이상) 손실의 우수하고 통신 손실 없게된다.With respect to aging deterioration, to protect against fire due to ignition and heat with the function of thermal runaway, when the heat is generated, the solder 23 melted during heat generation is included in the surge protector 20, so that the solder 23 melts, FIGS. 4, the stopper between the bending terminal 25 and the varistor substrate 22 supporting the tee-shaped hammer 28 of the surge protector 20 disappears, and thus the elastic restoring force of the spring 27 and the hinge shaft 26 are centered. Rotating counterclockwise, the tee hammer 28 operates the contacts of the double contact switch 29 in reverse. This is to ensure that the first switch (SW1) of the double contact switch (29) turns on the lighting LED (61) as shown in FIG. 5 to confirm that the surge protector is operating, and at the same time, the second switch separated from the power input terminal as shown in FIG. (SW2) causes the operation (turn-on) of the fact that the MSI 66 checks through the input ports I1 and I2, and the MSI 66 drives the output ports O1 and O2 to correspond to the relay 65 ) Is magnetized to turn on the internal contact, and MSI 66 recognizes it as a relay operation at the input ports (I3, I4) and ignites the line to a power line communication line (transmission line) through a communication port (not shown). This is because the abnormal state as described above is communicated to the external upper power system system as a contact signal (for example, RS-485 communication), and the signal for loss of the surge protection device is continuously transmitted, which is separated from the power input terminal and the system. In addition, the present invention is excellent in communication loss (less than 0.2 dB) and reflection (more than 20 dB) loss and no communication loss when communicating (eg RS-485 communication) with an external high-power system system as a contact signal.

서지 보호 기능이 상실될 경우에도 외부 서지 대해서 가스방전관(GDT)을 사용하므로 과전류에 충분한 내성이 있다.Even when the surge protection function is lost, the gas discharge tube (GDT) is used for external surges, so it is sufficiently resistant to overcurrent.

본 발명은 조립식으로 상케이스(30)와 하케이스(40)와 서지보호기회호기판(10)을 그 사이에 설치하고, 상하케이스는 도시하지 않은 나사를 사용하여 나사공(44)을 통하여 조립하므로 조립이 용이하고 일부 부품 교체시에도 분해하여 교체 가능하고, 측면에 통기공(36)을 두어 서지 동작기능시 외부 환경에 신속하게 이상가스를 방출 할 수있도록 기구 측면에 벤트홀 기능을 수행하므로 발화시 가스 발생을 방지하여 안전사고를 예방토록 한다. In the present invention, the upper case 30 and the lower case 40 and the surge protection circuit board 10 are installed therebetween, and the upper and lower cases are assembled through a screw hole 44 using screws (not shown). Because it is easy to assemble and can be disassembled and replaced even when replacing some parts, vent holes 36 are placed on the side to perform vent holes on the side of the instrument to quickly release abnormal gas to the external environment during surge operation. Prevents gas accidents during ignition to prevent safety accidents.
