电力施工吊车接地装置的设计

Design of earthing device for power construction crane

针对电力施工吊车吊臂与邻近带电体不能保证安全距离,容易引起带电体放电,造成操作人员触电事故的问题,对现场作业环节进行深入分析,设计了一种使用灵活、结构简单,方便的电力施工吊车接地装置,并应用到35 k V及以下输电线路施工中。应用效果表明:该接地装置有效地避免了电力施工人员人身触电事故的发生,提高了吊车作业的安全系数,具有一定的实用价值。

Aiming at the problem that crane boom cannot guarantee the safe distance with nearby electrified body resulting in electrified body discharge and the operator electric shocking accident happening in electric construction, deeply analyzes site work links, designs a new type of crane earthing device for power construction, It has characteristices of flexility, simpleness and convenience, and can be that crane applied in 35 kV and below transmission lines construction. The application result shows earthing device effectively avoid the accident of personal electric shocking in electric construction, improve the safety coefficient of crane work and has practical application value.
