13 熔断器检查与更换 Inspection and Replacement of Fuse 对于正常运行的熔断器, 其寿命可在 20 年以上, 若定期检修设备时, 可用测量熔断器内阻的变化来判断其是否变化, 内阻的变化范围在 ±10% 之内 在更换熔断器时必须非常小心, 因为限流熔断器在运行时有一个安全范围, 它不能保证每一个故障条件均在其安全范围内, 如开关装置的脱扣失灵, 或熔断器低于其最小分断电流下动作等 为安全起见, 至少要等待熔断器动作 10 分钟以后和电路被负荷开关隔离开, 且接地开关合闸, 熔断器二端均接地的条件下才能更换, 一定要保证熔断器在不带电的条件下更换 三工位隔离开关处于接地位置且负荷开关处于合闸状态 ( 接地 ) 时, 方可打开熔断器室门 在熔断器室门打开后, 用专用工具拧松螺钉, 即可按顺序取出熔断器, 在取出熔断器时, 需小心轻拿, 以免损坏装熔断器的壳体, 同时检查硅橡胶头有无损伤 在完成熔断器更换后, 在装入硅橡胶堵头之前, 需将熔断器筒与硅橡胶头接触部分用无水乙醇擦干净, 待干燥后, 插入熔断器组件并旋紧 The fuse at normal operation will have a service life for more than 20 years. If the equipment is maintained regularly, it can measure the changes of internal resistance of fuse to make judgment. Generally the change tolerance is within ±10%. A special attention must be paid in fuse replacement, because current-limiting fuse should operate safely within a range, which cannot ensure every fault falling within the range, i.e. tripping fault of switchgear, fuse operation below minimum breaking current etc. For the purpose of safety, the fuse can be replaced after it has operated for 10 minutes, the circuit is disconnected by load switch, the grounding switch is off and the two ends of fuse are grounded. Make sure the fuse is replaced without power supply. When the three-position disconnecting switch is at grounding position and the load switch is at OFF (grounding) position, the door of fuse cubicle can be opened. After the door is opened, loosen the screws with special tools and take out fuse in a good order. Handle with fuse carefully, and pay attention not to damage the fuse housing. Meanwhile, check the damage of silicone rubber head. After fuse installation and before silicone rubber plug insertion, the contact between fuse cylinder and silicone rubber should be cleaned with absolute ethyl alcohol. After drying, insert fuse assembly and tighten it. 验收试验及投入运行前的准备工作 Acceptance test and preparations before putting into operation 验收实验项目 Acceptance items a. 根据订货资料检查柜内安装的电气元件的型号 规格是否相符 ; b. 检查紧固件是否有松动, 发现有松的应予以拧紧 ; c. 手动操作隔离开关 熔断器 机械程序联锁 3~5 次, 应灵活无卡滞现象, 动作精确, 程序无误 ; d. 检查二次接线是否符合图纸要求, 在主回路不通电情况下对二次线路进行动作实验, 各种二次元件应符合设计要求, 各继电器动作应准确可靠 ; e. 主回路电阻测量, 测量方法采用直流压降法, 通以 100A 电流, 测其电压降 ; f. 二次回路绝缘强度试验, 在导体与外壳之间, 施加交流 50Hz 电流 2000V 历时 1min 应无击穿放电现象, 二次回路中有电子器件部分, 试验电压由制造厂与用户商定 ; g. 主回路工频绝缘电压试验, 在相对地和相间施加交流 50Hz, 根据开关设备的额定电压, 按 GB311.1 规定的 80% 历时 1min 应无击穿闪络现象 a.check the model and specification of electrical components installed in the cabinet according to ordering data; b.check the looseness of fasteners.
