Product Details

GD31-AB15 계전기는 한국전력공사 345kV 변압기 보호 구매시방서에 따라 설계 제작된 345kV/154kV 변압기의 충격압력 계전기(96P)의 오동작 방지용 Digital 계전기 이고 GD31-AB16 계전기는 KEMC1120 규격에 따라 배전선로 Feeder 및 고압 Feeder, 분산전원 연계선로 등 3상 선로의 단락, 과부하 및 지락사고 등에 대한 방향성 보호에 적합하게 설계 제작 된 Digital 계전기 입니다.

GD31-AB15 계전기 내부에는 역전류 방지를 위해 대용량 Diode가 부착되어 있어 별도의 Diode를 장착할 필요가 없습니다. 이 2가지 계전기의 방향성 지락과전류 보호 시 EVT 3차측을 사용하지 않고 계전기 내부에서 연산을 통해 얻어진 영상전압을 이용해서도 보호가 가능합니다. 계측기능, Event사고파형 기록기능, 자기진단 기능, SCADA 연계통신기능도 갖추어져 있으며, 사고 분석과 설정 변경, 자료 취득 등을 쉽게 하도록 HMI 프로그램을 함께 제공합니다.

KYONGBO ELECTRIC
Power distribution equipment manufacturer, Indicating electric meter, Instrument transformer, Power converter, Protective relay and more
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.
