Fn ( c ) - 12 type h . v . load switch and fuse box is basied on the fn7 - 12series h . v . load switch . with operating mechanism . make the installation more simpler . can meet orders needs 12型系列高压负荷开关及熔断器组合电器是在fn7 - 12系列高压负荷开关的基础上，增加侧面操作机构，使得安装更加简捷方便，能够满足广大用户的不同要求。
Therefore , a set of operating devices of the fuse tube , which works safely and reliably , and can be operated easily , has been the operator ' s cherished desire for a long time 因此，一套安全可靠、操作简便、动作灵敏准确的熔管分合操作机构自然而然地成为熔断器操作人员的莫大心愿，这也正是研制本实验装置的初衷所在。
Any special requirements such as gear operation , motor operation , hydraulic or pneumatic cylinder operation , anti - friction bearing yoke sleeve , by - pass of drain , etc . must also be specified on purchase orders 如果有特殊要求，如齿轮操作机构，马达执行机构，液动或气动缸体执行机构，耐摩擦轴承轭架套管，排泄旁路，等等，在订购时都必须特别注明。
The motion of ship is nonlinear . the operating machine has nonlinearity such as dead zone and relay . the dynamic characteristic of ship is related to the conditions of sail such as wind , wave , flow and so on 船舶运动呈非线性，操作机构有明显的死区、继电等非线性；船舶运动动态特性又与航行工况密切相关，受风、浪、流等各种干扰，所以船舶操纵是极其复杂的运动。
