Description

Replacing tool and replacing method for replacing horizontally-arranged strain pole cross arm in electrified mode
Technical Field
The utility model relates to a relevant technical field of power equipment, specific saying so relates to a change instrument and change method of changing horizontal arrangement strain insulator pole cross arm with electricity.
Background
The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
At present, the cross arm or insulator string of a 10kV triangular tension pole has defects, and the commonly used operation method for replacing the tension insulator string and the cross arm in an electrified way is as follows: installing a new strain cross arm, a hardware fitting and an insulator string at a proper position above the original cross arm, completing the wire transfer work after insulation shielding, then removing the old insulator string and the cross arm, and completing the replacement work of the cross arm or the insulator string.
The inventor finds that when a strain pole cross arm or an insulator string arranged horizontally at 10kV has defects, if a new cross arm is additionally arranged above the original cross arm and is used as a force-bearing transferring tool for phase-by-phase transferring, enough interphase and phase-to-phase safety distance cannot be ensured, the danger coefficient is extremely high, and the space above the original cross arm is insufficient. Therefore, the operation is often performed in a power failure mode under the condition, so that the problems of wide power failure range, low operation efficiency and the like in work are caused, and the normal power supply of a client is influenced.
The scheme for replacing the cross arm and the insulator in the traditional mode is as follows:
the first scheme is as follows: and replacing the strain insulator string and the cross arm in an electrified way. After the working position is reached, the operator insulates and shields the live part and the grounding body which are possibly touched in the working process, installs a new strain cross arm, a hardware fitting and an insulator at a proper position above the original cross arm and insulates and shields the new strain cross arm, the hardware fitting and the insulator. After the preparation work before the wire transfer is finished, the connection between the wire and the original strain clamp is removed, the wire is hung on a new insulator string, the insulation tightener is slowly loosened to stress the new insulator string, whether each stress is normal or not is checked, the insulation shielding is recovered, other two-phase wires are hung on the new insulator string according to the same method, the insulation tightener is loosened, and the insulation tightener and a backup protection rope are removed after each stress is checked to be normal. And finally, removing the old insulator and the cross arm. The method has the defects that the requirement on the space distance above the original cross arm is extremely high, the danger coefficient is higher for the horizontally arranged electric poles, and the method is not used when the work is generally carried out.
Scheme II: and replacing the tension rod cross arm in a power failure mode. The power failure mode is a method for replacing a tension rod cross arm commonly used at present, namely a new cross arm is fixed above or below an original cross arm, a tension insulator string is temporarily replaced by a wire tightening tool to partially bear the force, the positions of the tension insulator strings are transferred to the new cross arm one by one, and after the transfer is finished and the tension insulator strings are firmly checked, the original cross arm is dismantled. The disadvantage of this solution is that it requires power failure to work, affecting the customer's power supply.
The third scheme is as follows: and the linear rod cross arm and the insulator are replaced in a live-line mode. The principle that the cross arm and the insulator replace facilities to transfer the stress of the overhead line is adopted, namely, two cranes or small suspension arms of an insulating bucket arm vehicle are respectively fixed with two side phase conductors which are subjected to insulation measures and bear the force, after a binding wire of the linear insulator is removed, the transmission lines on two sides are lifted to a proper height, the linear cross arm and the insulator are replaced by live working personnel, and finally the binding and fixing between the conductors and the insulator are recovered. The scheme is suitable for the work of replacing the straight pole cross arm and the insulator in an electrified way, and is not suitable for the work of replacing the tension-resisting pole cross arm in an electrified way.

The newly developed tool does not change the interphase distance of the line, increases the safety distance between the phase and the ground and between people and charged bodies, and realizes the charged replacement of the horizontally arranged strain pole cross arm and the insulator string.
