一种液压弹簧操动机构
摘要：
本发明涉及电开关的触点操作机构技术领域，特别涉及一种液压弹簧操动机构。该操动机构包括工作缸、弹簧储能装置、液压系统和发电活塞缸；操动机构在合闸和分闸过程中均具有缓冲行程；发电活塞缸包括发电活塞缸体以及活动装配在发电活塞缸体内的发电活塞，发电活塞连接有发电装置；发电活塞缸体的被发电活塞分隔的两个腔中，一个连通液压系统中的油箱，另一个在工作缸的上端部连通工作缸内腔；或者，发电活塞缸体的被发电活塞分隔的两个腔中，一个连通液压系统中的油箱，另一个在工作缸的下端部连通工作缸内腔。该操动机构用于解决现有技术中的操动机构在使用时造成的能量浪费和存在密封失效的安全隐患的问题。
摘要（英）：

The invention relates to the technical field of contact operating mechanisms of electric switches, and especially relates to a hydraulic spring operating mechanism. The operating mechanism comprises aworking cylinder, a spring energy storage device, a hydraulic system and a power generation piston cylinder. The operating mechanism has a buffer stroke in the closing and opening processes. The power generation piston cylinder comprises a power generation piston cylinder body and a power generation piston movably assembled in the power generation piston cylinder body, wherein the power generation piston is connected with a power generation device; one of the two cavities, which are separated by the power generation piston, of the power generation piston cylinder body is communicated with anoil tank in the hydraulic system, and the other is communicated with an inner cavity of a working cylinder at the upper end part of the working cylinder; or, one of the two cavities, which are separated by the power generation piston, of the power generation piston cylinder body is communicated with oil tank in the hydraulic system, and the other is communicated with the inner cavity of the working cylinder at the lower end part of the working cylinder. The operating mechanism is used for solving the problems of energy waste and potential safety hazard of sealing failure caused by the use of the operating mechanism in the prior art.
