Live-line working method for changing double-circuit line triangularly-arranged straight pole into strain pole

Abstract

The invention relates to a live working method for changing a double-circuit line triangularly-arranged linear pole into a strain pole. Comprising the following steps of S1, performing electricity testing on an insulator and a cross arm, S2, performing insulation shielding on an electrified body and a grounding body, S3, removing a binding wire, S4, lifting a three-phase wire, S5, fixing an insulation drainage wire bracket, S6, fixing the three-phase wire on a strain cross arm shielding cover, S7, performing breaking work on a near-side phase wire, S8, performing connection work on a near-side phase wire lead, and S6, performing connection work on a near-side phase wire lead. S9, connecting and disconnecting a far-side-phase wire and a middle-phase wire and connecting a lead wire; S10, dismounting a tension-resistant cross arm shielding cover; S11, dismounting an insulating drainage bracket; S12, dismounting an insulating shield; the wire lifting device has the advantages that due to the fact that lifting of the three-phase wire is achieved in the S4, the air gap and the safety distance between the wire and the cross arm can be effectively controlled, the safety performance during operation is greatly improved, the wire lifting device is remotely controlled by a ground electrician, the labor intensity of operators can be lowered, and the labor burden is relieved.

Description

technical field [0001] The invention relates to a live working method for changing a double-circuit line triangularly-arranged linear rod into a tension rod. Background technique [0002] Most of the current distribution network lines are set up with double circuits, which usually have the following defects: there are few circuit breakers in the double-circuit delta arrangement, and the phenomenon of line crossing is prominent. In order to reduce the large-scale power outages caused by the above reasons, improve the reliability of power supply, reduce unnecessary power outage losses and the impact of power outages on customers, it is necessary to carry out bypass live work, and the bypass cable must be a tension rod. In order to solve this problem, it can be realized by changing the electrified linear pole into a tension pole, but at present, the method of changing the electrified linear pole into a tension pole is mostly by insulating gloves, and This kind of edge glove op...

Problems solved by technology

[0002] The current distribution network lines are mostly double-circuit erection, which usually has the following defects: the double-circuit triangular arrangement has fewer breaking switches, and the phenomenon of line crossing is prominent. Once the line needs to be repaired, it must cooperate with each other to cut off the power of the whole line, and the scope of influence is large.

In order to reduce the large-scale power outages caused by the above reasons, improve the reliability of power supply, reduce unnecessary power outage losses and the impact of power outages on customers, it is necessary to carry out bypass live work, and the bypass cable must be a tension rod. The actual work In China, straight rods are often encountered. Therefore, in order to solve this problem, it can be realized by changing the charged straight rods into tension rods. This kind of insulated glove operation method usually has the following problems: manual operation is used throughout the whole process, and the labor intensity of the operators is high; when replacing linear rod insulators and cross-arms, most of them use insulating cross-arms, and the installation of insulating cross-arms is inconvenient. Raising the height between the wire and the cross-arm will cause the distance between the wire and the cross-arm to be small, which requires skilled operators, and the operation is difficult
