Description
Technical Field
The invention belongs to the technical field of electric power operation auxiliary tools, and particularly relates to a vertical arrangement type double-suspension vertical wire clamp temporary protection device and a pin supplementing pretreatment method.
Background
The vertically arranged double suspension clamps (hereinafter referred to as "clamps") are very common and indispensable important parts used on overhead power transmission lines, and the firmness of installation directly influences the operation safety of the overhead power transmission lines.
The specific structure of the wire clamp is shown in fig. 1, two wire clamps 100 clamp two wires 200 arranged in parallel up and down along the horizontal direction, so that the overhead transmission line is realized. In order to fix the two wire clamps 100 to each other, in fig. 1, screws 310 are provided at upper and lower ends of the wire clamp 100, the screws 310 sequentially penetrate through the two wire clamps 100, and two nuts 320 are provided on the shafts of the screws, so that the two wire clamps 100 are clamped; once the nut 320 is disengaged from the screw 310, the two clamps 100 will separate and the overhead conductor will fall off, causing immeasurable serious loss.
In order to ensure that the combination of the screw 310 and the nut 320 is stable, a cotter pin 400 is usually used to fix the screw in the prior art.
Specifically, a hole penetrating in the radial direction is provided on the screw 310 located outside the nut 320, the cotter 400 is inserted into the hole such that the head end and the open end of the cotter 400 are located at both sides of the screw 310, respectively, and then the open end is snapped to a horizontal state, thereby restricting the cotter 400 from moving in the axial direction of the hole, and the head end of the cotter 400 restricts the nut 320 from moving on the screw 310.
The cotter pin is easy to generate rust because the power transmission line is exposed in the natural environment for a long time when running and is attacked by various meteorological conditions (such as strong wind, ice and snow, temperature change, lightning stroke and the like) and other external adverse factors. The rusted cotter pin has low structural strength and is easy to break and fall off in operation, so that the power transmission line is disconnected and other faults are caused.
In the national power grid company 'overhead transmission line operation and maintenance management regulation', the missing of the cotter pin belongs to an emergency defect and needs to be supplemented in time. The existing pin supplementing methods are of two types, namely 'power failure pin supplementing' and 'electrified pin supplementing', and the two pin supplementing methods have the following advantages and disadvantages:
1. and (3) power failure pin repairing: through proposing the power failure application or combining the circuit maintenance plan that has a power failure, under the uncharged condition of circuit, the operating personnel carries out the benefit round pin operation to benefit round pin department along the insulator. The method does not need complicated preparation work, saves the operation time, and has no electricity in the operation and no electric shock hazard.
However, the power failure of the application line causes economic loss to the electricity consumers, and some lines even cannot be powered off. If the pin is repaired in the overhaul period, the discovered defects cannot be eliminated in time, and the pin repairing operators need to put down the wires to the end parts of the insulators, so that the process has certain dangerousness.
2. And (4) live pin repairing: under the condition that the line normally runs in a live mode, the operator climbs the insulating rope ladder to the pin supplementing position to supplement the pins while wearing the whole set of shielding clothes. The method has the advantages that the line does not need to be powered off, the loss of power utilization customers caused by power failure is avoided, and hidden dangers can be discovered at any time and eliminated at any time; the operating personnel directly connects to benefit round pin department through climbing the insulating ladder, need not to descend the wire.
However, the method has long preparation time before operation, low efficiency and needs more personnel for matching; just because the preparation time is overlength, there is the risk that the fastener drops, is unfavorable for using in the actual work.
Therefore, the advantages and disadvantages of comprehensive power failure pin supplement and live pin supplement in the prior art are needed, and the pretreatment device capable of preventing the wire clamp separation condition caused by the shedding of the split pin is provided, so that the power failure pin supplement can be carried out in reasonable time, the economic loss is reduced, and the safety of operators is ensured.
