Abstract

The invention discloses a short-circuit cable clamp with characteristics of quick loading and unloading and a short-circuit implementation method thereof. A first wire slot with two open ends is formed in a bottom cover; and a plurality of glands arranged side by side are hinged to the bottom cover by a connecting shaft. A second wire slot with two open ends is formed in the surface of each gland.A mounting plate is fixedly connected to one end, away from the connecting shaft, of each gland; a through hole is formed in each mounting plate; the two ends of the mounting plates along the long axis directions of the second wire slots face limiting flanges respectively; the limiting flanges are fixedly connected with the bottom cover; and arc grooves with two open ends are formed in the surfaces of sides, deviating from the directions of the mounting plates, of the limiting flanges. In addition, connecting elements include limiting shaft rods, locking screw rods, and nuts; the two ends ofeach limiting shaft rod are arranged in the arc grooves of every two limiting flanges facing one mounting plate; the locking screw rods are fixed at the limiting shaft rods; and the nuts sleeve the locking screw rods. Therefore, a problem of long time consumed by high-altitude short circuit of the short-circuit cable clamp in the prior art is solved; and thus objectives of shortening the short-circuit connection working time and reducing the potential safety hazard are achieved.

Description

technical field [0001] The invention relates to the field of power grids, in particular to a quick-loading and dismounting short-circuit clip and a short-circuit method thereof. Background technique [0002] In recent years, with the intensification of climate change and the increase of extreme weather, the 110kV ~ 500kV power lines are very easy to be overloaded in winter and summer. Overloading the line will cause the connector to heat up or even burn out. Therefore, hot treatment of hot joints is one of the most common maintenance tasks in power systems. In order to ensure the normal power supply during the replacement of the connector, it is necessary to connect a bypass with a short-circuit wire at both ends of the connector to allow the current to flow through the short-circuit wire. This is the short-circuit wiring operation in the power industry. In the prior art, it is common to use such as attached figure 1 The stud-type T-clip shown is used as a short-terminal ...
