Embodiment Construction

[0012] see figure 1 , the insulated bucket arm truck lifting wire operation method of the present invention comprises the following steps:

[0013] Install the three go-a-go-one insulating pulley blocks 3 on the insulating arm 2 of the 26m bucket arm truck respectively, the distance between the three go-go-go-one insulating pulley blocks 3 is 1m, and then control the bucket arm car to adjust the insulating arm to the wire 1 2m above, install a guide insulating pulley block 4 composed of three insulating pulleys side by side on the metal arm 6m away from the top of the insulating arm, and pass the insulating tail rope 5 of the insulating pulley block 3 through the guide in turn. Insulated pulley block 4, the top of the insulating tail rope 5 is provided with a boom tackle; put an insulating sleeve on the place where the wire 1 is lifted, place the wire 1 in the boom tackle, close the safety, and pull down the insulation tail rope 5 The other end of the wire 1 is slowly lifted ...

Abstract

The invention relates to an operational method for lifting a 10kV-lead wire of an aerial lift device with an insulating arm. The method comprises the following steps of: installing an insulation pulley device and lifting the lead wire. The operational method of the invention has the characteristics of safety, reliability, clear and perspicuous steps, easy operation, suitable insulation and isolation measures in an operational process and high safe coefficient, solves the problems of turning off power for standing a pole in operation such as line capital construction, business expansion, overhauling, emergency repair and the like, greatly improves power supply reliability. The operational method has a very great practical value in enlarging live-wire work fields and improving power supply reliability in power industry technology progress growing today.

Description

technical field [0001] The invention relates to a live working method for a power distribution line, in particular to a working method for lifting a wire by an insulating arm truck. Background technique [0002] With the continuous growth of social electricity demand and the rapid development of distribution network, it is impossible to add new equipment to the line near the location where the user applies for electricity. If there is a power outage, the reliability of power supply will be affected. [0003] To add electric poles, blackout construction is necessary. The whole process takes a long time, and a large amount of power will be lost, which will affect the reliability of power supply. After the construction is completed, recommissioning operations are required, which increases the scheduling operation steps. If a branch line is drawn from a remote unequipped straight pole, or a cable is put into the house, the construction cost will be greatly increased. Content...
