Description

大容量超高压合闸电阻
技术领域
本实用新型涉及超高压断路器技术领域，特别是一种大容量超高压合闸电阻。
背景技术
超高压合闸电阻是抑制高压断路器在电力系统中关合时所产生的操过电压的装置，根据电力系统的要求，超高压合闸电阻需要的阻值较大，通常在400Ω～1500Ω；由于受电阻片生产工艺限制，每片电阻片的阻值较小，因而需用的电阻片数量较多，其缺点是热容量比较小，合闸电压过高，不能够满足超高压断路器在电网中的多次连续关合的要求。
发明内容
本实用新型的目的是提供一种绝缘性能优良，阻值及热容量灵活可调，热容量大，能够满足超高压断路器在电网中的多次连续关合要求的大容量超高压合闸电阻。
本实用新型是这样实现的，它包括聚四氟乙烯绝缘板、合闸电阻片、导电片和两根绝缘杆，其特征是多片电阻串联构成合闸电阻片，合闸电阻片安装在两根绝缘杆上，两根绝缘杆上对应的合闸电阻片通过导电片串联。
本实用新型是通过多片合闸电阻片的串联装配方式实现电阻装置的大容量超高压性能，具有绝缘性能优良，阻值及热容量灵活可调，热容量大，能够满足超高压断路器在电网中的多次连续关合要求的优点，从而有效地降低合闸过电压。可以应用于550kV及以上的超高压电力系统的开关设备中。
附图说明
以下结合附图对本实用新型做进一步的描述；
图1是大容量超高压合闸电阻的结构示意图。
具体实施方式
如图1所示，该大容量超高压合闸电阻包括聚四氟乙烯绝缘板1、合闸电阻片2、导电片3和两根绝缘杆4，多片电阻串联构成合闸电阻片2，将合闸电阻片2安装在两根绝缘杆4上，同一根绝缘杆4上的合闸电阻片2之间是绝缘的，两根绝缘杆4上对应的合闸电阻片2通过导电片串联。
