青海省首套变压器智能保护装置进入实用阶段

Core Viewpoint - The introduction of an intelligent protection device for transformers in high-altitude areas marks a significant advancement in ensuring the reliability of power grids in challenging environments [1][2]. Group 1: Device Development and Features - The intelligent closed-type neutral point protection device for transformers has passed on-site acceptance, specifically designed for high-altitude regions [1]. - This device addresses issues such as large discharge gap variability and high false action rates associated with traditional air-insulated protection systems [1]. - The device incorporates a closed tank filled with insulating medium, which houses protection gaps, arc sensors, and fast switches, enhancing operational reliability [1]. Group 2: Technological Innovations - The device features intelligent upgrades, including real-time monitoring and diagnostic capabilities, facilitating a shift from periodic maintenance to condition-based maintenance in substations [1]. - It has been granted four patents and has two core journal papers published, indicating a strong foundation in research and development [2]. Group 3: Future Applications and Impact - The device is expected to be applied in similar environments such as the Qinghai-Tibet Plateau and Yunnan-Guizhou Plateau, strengthening the safety of the national energy corridor in the western region [2].
