Description

온도변화 추세 비교분석을 통한 고장예측이 가능한 배전반Switchgear that can predict failures through temperature change trend comparative analysis
본 발명은 예측대상 배전반에 대한 온도변화 추세 비교분석을 통한 고장예측이 가능한 배전반에 관한 것으로, 구체적으로는 고압배전반, 저압배전반, 전동기제어반, 분전반 등 배전반 설비들의 환경 및 상태 정보 데이터를 기반으로 고장진단 및 고장사전예측 기능을 갖으며, 또한 다양한 지역에 분포하는 배전반 설비들에 대해 환경 및 상태 정보가 유사한 배전반 설비를 그룹화하고, 그룹화 내에서의 상대적 온도변화 추세 비교분석을 통해 정확하고 효율적인 고장진단 및 고장사전예측이 가능하고, 추가적으로 배전반 설비들에 대한 고장이력데이터 및 배전반 설비 정보들을 기반으로 배전반 설비의 고장사전예측은 물론 특히 변압기에 대한 노후화 예측 기능도 포함하는 온도변화 추세 비교분석을 통한 고장예측이 가능한 배전반에 관한 것이다. The present invention relates to a switchboard capable of predicting failure through a comparative analysis of a temperature change trend for a switchboard to be predicted. Specifically, a failure based on environmental and state information data of switchboard facilities such as high-voltage switchgear, low-voltage switchgear, motor control board, and switchboard It has diagnostic and failure prediction functions, and groups switchboard facilities with similar environmental and status information for switchboard facilities distributed in various regions, and performs accurate and efficient fault diagnosis through comparative analysis of the relative temperature change within the grouping. And failure prediction is possible, and failure through temperature change trend comparison analysis, which includes not only the failure prediction of switchboard facilities based on failure history data and switchboard facility information, but also the aging prediction function for transformers in addition It's about predictable switchboards.
발전소에서 생산된 전기는 수만V의 고압인 상태에서 송전선로를 통해 송배전이 되고, 수용가 측에서는 수만V 교류전압을 변압기 등의 배전반 설비를 통해 필요로 하는 전압으로 감압하여 각 수용가 또는 부하단에 전력을 공급하게 된다. 이 과정에서 필요한 것이 바로 폐쇄형 배전반 또는 배전반 설비라고 불리며, 표준 규격상으로는 고압배전반, 저압배전반, 전동기제어반, 분전반이 포함된다. The electricity produced in the power plant is transmitted and distributed through the power transmission line at a high voltage of tens of thousands of V, and on the consumer side, the tens of thousands of V AC voltage is reduced to the required voltage through a switchboard facility such as a transformer to supply power to each customer or load stage. will supply What is needed in this process is called a closed-type switchboard or switchboard facility, and the standard specification includes a high-voltage switchboard, a low-voltage switchboard, a motor control board, and a distribution board.
일반적으로 수용가의 전기실(배전반 설비)에서는, 공급받은 22.9kV의 전기를 변압기 등을 거쳐 380~220V로 변환되어, 저압배전반에서 분기되어 전동기 제어반이나 각 층 또는 각 실의 분전반을 통해 전기를 공급하게 된다. In general, in the consumer's electrical room (switchboard facility), the received 22.9kV electricity is converted to 380~220V through a transformer, etc. do.
이러한 과정에 사용되는 배전반 설비에 예상치 않은 고장이 발생하게 되면, 해당 고장요인이 수리될 때까지 전기가 공급되지 못하게 되거나 또는 변압기와 같이 고비용이 드는 설비의 경우 고장발생으로 변압기 전체를 교체해야 하는 비효율적인 유지보수가 이루어지는 문제점이 있었다. If an unexpected failure occurs in the switchboard equipment used in this process, electricity cannot be supplied until the cause of the failure is repaired, or in the case of a high-cost equipment such as a transformer, it is inefficient to replace the entire transformer due to a failure. There was a problem in which the maintenance was performed.
따라서, 이러한 문제점을 해결하기 위해, 배전반 설비 등에 대한 모니터링 등을 통해 고장을 사전에 진단하고 예측하고자 하는 시도들이 이루어지고 있으나, 기존의 고장예측 기술들의 경우 대부분 고장이 발생하는 시점에서 고장여부를 진단하는 정도에 그치고 있는 실정이며 또한, 고장을 예측하는데 사용하는 모니터링 정보 등도 관련 설비의 온도변화 등을 체크하는 수준에 머물러 있는 실정이다. Therefore, in order to solve this problem, attempts have been made to diagnose and predict failures in advance through monitoring of switchboard facilities, etc., but most of the existing failure prediction technologies diagnose failure at the time of failure. In addition, monitoring information used to predict failures remains at the level of checking temperature changes of related facilities.
