Description

Simple tool for adjusting lead sag

Technical Field

The utility model relates to a transmission line fortune dimension, maintenance technical field especially relate to a simple and easy instrument that adjustment wire arc hangs down.

Background

In the operation and maintenance, overhaul and acceptance of newly-built lines of the traditional power transmission line, the sag of the conducting wire is easily unqualified and exceeds the specified value of the design standard (the sag of the conducting wire and the earth wire should not exceed the design allowable deviation, namely +6.0 percent and-2.5 percent of the line below 110kV, and +3.0 percent and-2.5 percent of the line above 220 kV). The wire sag is too large, so that the safety distance between the lowest point of the line and the ground or a crossed spanning object does not meet the design requirement, and the inter-phase short circuit is easy to occur under the action of strong wind; the sag of the wire is too small, the stress of the tension-resistant pole towers at two ends of the tension-resistant section is increased, and the accidents of wire breakage and tower falling are easy to occur under the conditions of lowest air temperature and ice coating. At present, the adjusting plates are arranged on the tension tower insulator string hardware fittings of the overhead transmission line and used for adjusting conductor sag, but the adjustment can only be carried out under the condition of line power failure due to the fact that no special tool is arranged, and in the adjusting process, tools and appliances are heavy and more in needed personnel. A simple tool for adjusting the arc sag of the wire is developed, and the adjusting plate can be adjusted under the condition that a circuit is electrified, so that the aim of adjusting the arc sag of the wire is fulfilled.

The connecting plate side fixture (1), the steel anchor fixture (2), the two connecting side fixture wire barrels (3), the left-handed screw rod (5) and the right-handed screw rod (6) form a quadrangle in a surrounding mode.

The utility model discloses a use method: when the device is used, an overhead worker disconnects the lower part of the steel anchor clamp from the bolt B at the connecting plate B, clamps the triangular connecting plate in the U-shaped clamping groove on the connecting plate side clamp, clamps the steel anchor at the steel anchor clamp, fastens the lower part of the steel anchor clamp with the bolt B at the connecting plate B, tightens the upper side and the lower side to be connected with the connecting side clamp wire barrel, and adjusts the position of the screw hole on the adjusting plate to enable the conductor sag to reach the specified range.

1. The connecting plate side fixture of the simple tool for adjusting the lead sag has the advantages that the clamping groove at the front end can tightly clamp the triangular connecting plate, so that the purpose of fixing the connecting plate side fixture is achieved, the installation is convenient, and the deflection and the sliding cannot occur after the lead sag is stressed;

2. a steel anchor clamp of the simple tool for adjusting the lead sag can penetrate into a steel anchor of the hydraulic strain clamp, and a bolt in the middle of the steel anchor clamp is fixed in a steel anchor circular ring;

the beneficial effects of the utility model reside in that: the development of the simple tool for adjusting the conductor sag ensures that the operation of adjusting the conductor sag can be completed under the condition of live line, the number of times of line power failure maintenance is reduced in the operation and maintenance and rush repair processes of the power transmission line, and the reliability of power supply is ensured. This simple and easy instrument of adjustment wire arc sag quality is light, intensity is big, the structure is retrencied, convenient to use, and the good reliability, the required personnel of operation significantly reduce has improved maintenance work efficiency, uses and need not train, and the later stage need not maintain.
