AI Technical Summary

Problems solved by technology

Due to the uneven force of manual operation, the lifting mechanism will be twisted, and the lifting mechanism needs to be adjusted, so the work efficiency is not high
At the same time, when temporarily adjusting, it is necessary to climb back to the lifting mechanism at high altitude, lift the cross arm, and then climb up to the cross arm for operation, which is very time-consuming and laborious

Embodiment Construction

[0043] The present invention will be described in detail below in conjunction with the accompanying drawings, but it should be pointed out that the implementation of the present invention is not limited to the following embodiments.

[0044] A method for changing a loaded linear rod into a tension rod, comprising the following steps:

[0045] 1) Two electricians wear insulating protective equipment respectively, then enter the insulating bucket, and hang the safety belt safety hook;

[0046] 2) Two electricians adjust the insulating bucket to the lower side of the cross-arm of the live wire, and use the electroscope to conduct an electric test on the insulator and the cross-arm to confirm that there is no leakage;

[0047] 3) 2# electrician insulates and shields all charged bodies and grounded bodies within the scope of work in accordance with the shielding principle of "from near to far, from bottom to top, charged body first and then grounded body";

[0048] 4) The 1# elect...

Abstract

The invention relates to a method for changing a strain power pole of a linear rod with loads. The method comprises the following steps that 1) two electricians respectively wear insulation protectiveappliances, enter an insulation bucket, and hang a safety belt and a safety hook; 2) the two electricians adjust the insulation bucket to the lower side of an electrified wire crossarm, and use an electroscope to conduct live part verification on an insulator and the crossarm to confirm that there are no electric leakage phenomenons; 3) the second electrician conducts insulation shielding on allelectrified bodies and grounding bodies in a working range according to a shielding principle of 'from near to far, from bottom to top, and from the electrified bodies to the grounding bodies'; 4) thefirst electrician and a ground electrician cooperate to install a 10kV horizontal overhead wire lifter firmly and stably on a pole; the method is suitable for changing the strain power pole of the 10kV horizontal overhead line linear rod with the loads, can be applied in an electrified state on both insulation lines and bare wire lines, and can ensure air gaps between wires and the crossarm.

Description

technical field [0001] The invention relates to a method for converting a loaded straight rod into a tension rod, in particular to a method for converting a straight rod into a tension rod for a 10kV loaded horizontal overhead line by using an electric 10kV overhead wire lifter. Background technique [0002] The 10kV overhead distribution line network with the largest coverage is responsible for the main connection between the transmission line network and various users. Due to the low insulation level of the voltage level line, it is prone to failure under the action of atmospheric overvoltage, pollution or other external factors, and because the distribution line facilities in some areas are old and aging, there are many hidden dangers in the equipment, coupled with the rapid development of social economy, The ever-increasing number of companies reporting for installation of electricity, and the relocation of 10kV overhead distribution lines caused by infrastructure constr...
