In general, in order to determine whether there is a diagonal line or a live line when cutting an underground cable in a manhole, a phase-tracking determination equipment consisting of a transmitter (10), a receiver (20), a clamp sensor (30), and a TF sensor (40) is used as shown in FIG. Gi was used.

상기 상추적 판별기에 의한 진단방식은 도 2와 같이 발신기(10)에 의해 펄스가 지중케이블(50)의 도체에 가해지고 폐회로 내 펄스가 순환되면, 클램프 센서(30)가 펄스를 감지하고, 클램프 센서(30)와 연결된 TF 센서(40)를 통해 방향성(정방향 또는 역방향)을 확인하여 3상 확인하는 동작원리로 이루어진다. In the diagnosis method using the phase-tracking discriminator, as shown in FIG. 2, when a pulse is applied to the conductor of the underground cable 50 by the transmitter 10 and the pulse circulates in the closed circuit, the clamp sensor 30 detects the pulse, and the clamp It consists of an operating principle of confirming three phases by checking the directionality (forward or reverse) through the TF sensor 40 connected to the sensor 30.

그러나, 이와 같은 상추적 판별기를 사용하여 맨홀 내 지중케이블 절단작업 시 작업자 판단 실수에 의한 지중케이블 착오절단 고장을 예방하고 있으나, 현장 작업자의 상추적 판별기의 인식 부족, 작업 공간의 협소 및 현장 설치 등 활용에 장시간이 소요되는 이유로 상추적 판별기의 현장 활용도가 현저히 떨어진다는 문제점이 있었다. However, this type of vertical discriminator is used to prevent underground cable mis-cutting failures due to operator judgment errors when cutting underground cables in manholes. However, field workers lack awareness of the vertical discriminator, narrow work space, and on-site installation. There was a problem that the field usability of the lettuce discriminator was significantly reduced due to the long time it took to utilize it.

Referring to FIG. 6, the underground cable pulse detection method of the present invention includes the step (S300) of performing a load transfer on the target section of the underground cable 50 that requires three-phase confirmation and turning off the underground cable 50. ; A step (S310) of performing electric shock and discharge on the truce section of the underground cable (50); Installing several pulse detection lamp devices (100) on the load side of the target section of the underground cable (50) that requires three-phase confirmation (S320); Installing a transmitter (10) on the power side of the target section of the underground cable (50) for which three-phase confirmation is required and applying a pulse to the conductor (S330); A step (S340) of operating the pulse detection sensor 124 of the pulse detection lamp device 100 to detect a pulse applied to the conductor; And when the pulse is detected, the lamp 140 of the pulse detection lamp device 100 turns on to confirm the three phases (S350).

이 처럼, 본 발명은 기존 발신기(10)에서 해당 지중케이블(50)에 펄스가 보내지면, 지중케이블(50)에 끼워진 펄스감지 램프장치(100)의 펄스감지 센서(124)가 작동하여 펄스감지 램프장치(100)의 하우징(110) 내에 설치된 여러개의 램프(140)를 점등해 주는 지중케이블 펄스감지 램프장치 및 펄스감지방법이기 때문에 맨홀 내 지중케이블(50) 절단작업 시 사선·활선여부를 램프(140) 점등에 의해 시각적으로 즉시 판단할 수 있는 장점이 있다. As such, in the present invention, when a pulse is sent from the existing transmitter 10 to the corresponding underground cable 50, the pulse detection sensor 124 of the pulse detection lamp device 100 inserted into the underground cable 50 operates to detect the pulse. Because it is an underground cable pulse detection lamp device and pulse detection method that lights up several lamps 140 installed in the housing 110 of the lamp device 100, the lamp determines whether the cable is diagonal or live when cutting the underground cable 50 in the manhole. (140) It has the advantage of being able to be judged visually immediately by lighting.

또한, 지중케이블(50)에 끼워지는 펄스감지 램프장치(100)는 기존의 수신기(20)가 필요없는 결합형이기 때문에 맨홀 등 작업 협소공간에서 지중케이블(50)에 자유롭게 설치 및 철거가 용이할 뿐만 아니라 휴대 및 보관이 용이한 장점이 있다. In addition, since the pulse detection lamp device 100 inserted into the underground cable 50 is a combination type that does not require the existing receiver 20, it can be easily installed and removed from the underground cable 50 in narrow working spaces such as manholes. In addition, it has the advantage of being easy to carry and store.
