摘要:
水平伸縮式隔離開關主閘刀在分、合閘過程中存在重力矩的變化,爲了減少機構的輸出力矩且使主閘刀運行平穩,需在下導電管內配置合適的平衡彈簧以匹配主閘刀分、合閘過程中的重力矩變化。平衡彈簧的配置是否科學直接影響著整個主閘刀系統的平穩與否,文中以1 120 kV直流隔離開關爲研究對象,通過理論分析了整個主閘刀系統的機械運動特性,提出了平衡彈簧的一般設計方法。
Abstract:
There are gravitational torque changes of the horizontal retractable disconnector main blade during the opening and closing process. In order to reduce the output torque of the mechanism and make the main blade run smoothly, it is necessary to configure a suitable balance spring in the lower conductive tube to match the change of the gravitational torque of the main blade during the opening and closing process. The configuration of the balance spring directly affects the stability of the entire main blade system. The paper starts with the basic theoretical analysis, takes 1 120 kV DC disconnector as research object, discusses the mechanical motion characteristics of the entire main blade system, and proposes the general design method of the balance spring.
