当变电站某条线路进行停电检修作业时，需要将相应间隔断路器已储满的能量泄掉，实现闭锁功能，从而防止断路器误动作。本文以液压弹簧操动机构的释压原理为理论基础，结合实际应用，介绍了一种断路器液压弹簧机构的远程泄压控制系统。该系统通过安装在液压弹簧机构的电动推杆顶压液压阀，电动推杆运动到位后，液压弹簧机构开始泄压，释放储能弹簧能量。液压机构只有在电动推杆恢复后，才能通过储能电机开始储能。该系统可以在断路器分闸后控制液压弹簧机构自动泄能，有效防止断路器误合事故的发生。本系统适用于无人值守变电站。%When a line of substation need to cut power for maintenance. The corresponding circuit breaker has been stocked need to release energy in order to achieve locking function to prevent the breaker malfunction and avoid accidents. The theoretical basis of this paper is the principle of release the pressure of hydraulic spring operating mechanism. Combined with practical application, it describes a remote control system for the relese energy of spring breakers hydraulic mechanism. The system is used putting electric to press Hydraulic valves which is installed in the hydraulic spring mechanism. When the electric putter movement to the energy release position, hydraulic spring mechanism start to relief then the energy of storage spring is released. Hydraulic mechanism only after electric putter back to original, charging motor can start work and store energy. you can control the hydraulic spring mechanism automatic release energy after circuit breaker opening, effectively prevent the circuit breaker closing mistakenly accident. The system is suitable for Unattended substation.
