Description

배전반 감시 시스템 및 그것의 동작방법Switchgear monitoring system and its operation method
본 발명은 배전반 감시에 관한 것으로, 보다 구체적으로는 원격에서 모니터링이 가능한 배전반 감시 시스템 및 그것의 동작방법에 관한 것이다.The present invention relates to a switchboard monitoring, and more particularly, to a switchboard monitoring system capable of monitoring remotely and a method for operating the same.
배전반 내에는 전력변환 및 전달, 계측을 위한 많은 전력기기들이 배치되어 있다. 그러나 이들 전력기기들은 전기적, 열적, 화학적 스트레스 및 진동, 환경적 요인 등에 의해 열화되거나 기구적 결속력이 약해져 절연이 파괴되고, 결국 사고로 치닫을 수 있다. 따라서, 배전반의 상태진단이 반드시 필요하다.Many power devices for power conversion, transmission and measurement are arranged in the switchboard. However, these power devices are deteriorated by electrical, thermal, chemical stress and vibration, environmental factors, etc., or mechanical binding is weakened, and insulation is destroyed, which can lead to accidents. Therefore, it is necessary to check the status of the switchboard.
종래의 배전반 상태진단을 위한 방법으로는 부분방전 센서 또는 온도센서 모듈을 단일로 취부하여 감시하고, 이를 이용하여 이상 여부를 감시하였다. As a conventional method for diagnosing the status of the switchboard, a partial discharge sensor or a temperature sensor module is mounted as a single unit and monitored for abnormality.
예를 들어, 배전반의 온도 감시를 위해 IR 온도센서, RS-485케이블, 배전급 DAU 및 HMI 디스플레이를 포함하여 배전반 감시 시스템이 이루어젼다. 이때에, IR 온도센서는 배전반의 내부에 설치 되는데, 온도 감시가 필요한 부스바 및 케이블의 정면에 위치 한다. 그리고, 측정된 데이터 값은 RS-485 케이블을 통해 배전급 DAU에 전달 된다. 배전급 DAU는 측정된 데이터를 배전반의 전면에 별도의 디스플레이 장치를 설치 하여 사용자가 확인 할 수 있다.For example, for monitoring the temperature of the switchboard, a switchboard monitoring system has been implemented, including an IR temperature sensor, an RS-485 cable, a power distribution DAU, and an HMI display. At this time, the IR temperature sensor is installed inside the switchboard, and is located in front of the busbar and cable that needs temperature monitoring. Then, the measured data value is transmitted to the distribution-grade DAU through the RS-485 cable. The distribution DAU can be checked by the user by installing a separate display device on the front of the switchboard.
한편, IR 온도 센서는 부스바, 케이블 등에서 일정한 절연거리를 확보한 위치에서 취부해야 한다. 따라서, 기존의 설치 현장에 IR 온도 센서를 적용하려면 설치 지그 설계 및 판넬 구조에 대한 수정 작업이 필요하다. 나아가, 판넬에 대한 절연 문제도 검토하여 재설계해야한다. 그리고, 측정한 데이터를 DAU에 전달 하기 위한 추가적인 배선 작업도 필요한데, 이는 기존 설치 현장에서는 상당히 어렵고 복잡하다. 또한, 추가로 부품이 취부 되고 배선작업을 하므로, 그러한 절연 설계로 인하여 배전반 사이즈도 커지게 된다. On the other hand, the IR temperature sensor should be installed at a location where a certain insulation distance is secured from the busbar, cable, etc. Therefore, to apply the IR temperature sensor to the existing installation site, it is necessary to modify the installation jig design and the panel structure. Furthermore, the insulation problem for the panel should also be reviewed and redesigned. In addition, additional wiring work is required to transfer the measured data to the DAU, which is quite difficult and complicated in the existing installation site. In addition, since additional components are installed and wiring is performed, the size of the switchboard is also increased due to the insulation design.
따라서 본 발명은, 기존의 배전반의 구조와 절연 설계를 다시 수행할 필요 없이 감시 데이터를 취득할 수 있고, 취득된 데이터를 처리 및 분석하여 이상 상태를 감시하고, 이상 상태시 적절한 솔루션을 빠르게 제공할 수 있는 배전반 감시 시스템 및 그것의 동작방법을 제공하는데 그 목적이 있다. Therefore, the present invention can acquire the monitoring data without having to perform the structure and insulation design of the existing switchboard again, process and analyze the acquired data to monitor the abnormal condition, and quickly provide an appropriate solution in the event of an abnormal condition It is an object of the present invention to provide a switchgear monitoring system and a method of operation thereof.
