Product Details

본 계전기는 한국전기공업협동조합 규격(KEMC1120)을 기준으로 설계 제작되었으며, OCR ×3, SGR×1, OVGR×1를 동시 내장하고 있어 비접지 고압 배전선로에 있어서 단락 및 과부하, 전기기기의 절연열화 또는 파괴, 전로와 대지간의 접촉사고에 의한 지락사고 발생 시 영상변류기 (ZCT)를 통한 영상전류와 접지 변압기(EVT) 3차측에서 유기, 검출되는 영상전압의 크기와 위상에 의해 동작하는 계전기로 사고 시 이를 검출하여 선로의 차단 또는 경보하여 기기 및 전로를 보호할 수 있는 Digital 계전기로서 다양한 동작시간, 정확한 동작 전압/전류의 정정을 쉽게 할 뿐만 아니라 고장 사고시의 Data를 저장하고 있어서 전선로의 신뢰성 향상에 큰 도움이 됩니다.

KYONGBO ELECTRIC is constantly striving to become a world-class power equipment company by supplying excellent quality power products to various fields that require power, including water and switchboards, power generation, transmission and transformation, shipbuilding, plants, railways and subways. Since its establishment in 1967, when the domestic power industry had a weak foundation, KYONGBO ELECTRIC has contributed to the development of the domestic power industry by steadily supplying a wide range of high-quality power products ranging from indicating electricity instruments, instrument transformers, power converters, protective relays, and leakage alarms necessary for power measurement, transformation, protection, and monitoring, and has grown into a leading company in the power equipment field. In particular, based on various know-how and technology accumulated over a long period of time, such as developing protective relays and 0.2% class power converters for the first time in Korea, we have acquired various quality certifications such as international standard quality management system (ISO9001), nuclear quality certification (KEPIC), CE certification, KS marking certification (KS C 1706, 1708, 60051-2,3,4,5), etc. However, we are not satisfied with this, and to achieve our long-term vision of becoming a "global powerhouse in the power industry," we will focus on investing available capital and resources in human resource development and technology development based on financial security, actively discovering and nurturing creative talents and conducting systematic education and training to maximize the capabilities of all employees, while striving to create customer value through the development of multi-functional and eco-friendly new products that combine advanced power technology with electronics and IT technology, and through quality and service innovation efforts. We will also strive to create an innovative corporate culture, enhance corporate value, and improve customer value by improving corporate activities, organization, and work processes more efficiently and sharing value among employees, so that the three will naturally synergize, and we will do our best to seek a path of win-win cooperation and lay the foundation for sustainable growth through support and cooperation with relevant suppliers.
