Abstract
The invention, which belongs to the technical field of the live-line work engineering of the distribution network line, discloses a live-line replacing method of a straight pole cross arm of a distribution network line. An insulated platform is used as a main insulation unit and the operating worker uses the set of individual insulation protection tools. With the insulating-glove-based direct working method, the worker uses the insulation shielding tool carries out associated shielding on electrification equipment and thus an electrified body is directly contacted to carry out replacement and installation work. And according to the insulating-bar-holding working method, the worker uses an insulating holding pole to fix and support the electrified body temporarily. Therefore, the normal power supplying of the distribution line in an operating mode can be guaranteed; the number of times of the main line can be reduced; and the power supply reliability can be ensured. The economic benefits of multiple power supply can be realized and the continuous power supply can be guaranteed; and more economic value can be created for the society.
