Product Details

전류로 동작하는 유도형 회전력 평형식으로 동작Coil과 억제Coil과의 이개의 전자석요소를 부착시켰으며, 동일 회전원판에 대해서 역방향의 회전력을 보완시키고 있다. 두개의 억제Coil의 중성점에 동작Coil을 접속시키면 전자는 접점을 여는 방향으로 원판을 회전시키고 후자는 접점을 닫는 방향으로 회전한다. 상시에는 변류기의 이차전류는 평형 되어있으므로 동작Coil에 전류는 흐르지 않고 억제Coil에 흐르는 전류의 회전력에 의해서 접점이 열리게 된다.

내부고장일 때는 평형이 무너지고 동작Coil에 차전류가 흘러 일정치 이상이 되면 동작Coil의 회전력은 억제Coil에서 흘러 접점을 닫으므로, 계전기는 동작한다. 따라서 동작전류는 일정치는 아니고 회로전류에 비례하여 증가한다. 외부고장일 때는 억제Coil에 의한 접점을 개방된 변류기의 특성의 상위에 따라 약간의 차전류가 생기더라도 접점을 막지는 않습니다.

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.
