摘要
直流开关设备是直流输电系统换流站的重要设备,主要用于直流输电系统运行方式的转换、故障的清除,以及检修隔离等目的,关系到输电系统的可靠性、可利用率、可维护性。笔者以相关国家标准、技术导则为技术支撑,根据直流输电系统不同运行方式和控制策略对直流开关设备结构的特定要求,综述了直流转换开关、隔离开关、接地开关及旁路开关的用途和分类;按照基本原理、结构类型、结构特点等方面对各类开关设备进行了分析比较,提出了设备研发的技术难点和发展方向,以供研发人员和工程设计者参考。
DC switchgear is the key device in the DC the commutation of various operate manner, clearance transmission system, which influences the rehability, transmission system convert station and is applied to of the fault, maintenance and disconnect in the DC availability and maintainability of the transmission system. According to the relative GB standards, technical guidelines and rules as theoretical support, on the basis of the specific requirement of various operate manner and control strategy in the DC transmission system for DC switchgear structure. The purpose and the class is discussed include DC transfer switches, disconnectors, earthing switches and by-pass switches. The analysis and contrast is carried out for DC switchgear based on the basic principle, structure type and characteristic. The technical difficulties and development trends of DC switchgear are put forward. This study provides a reference for the relative researchers and project designers.
