Device for mounting high-voltage line T-type clamp in live-line working mode

Abstract

The invention discloses a device for mounting a high-voltage line T-type clamp in a live-line working mode. The device includes a lifting platform, a four-axis platform and a tail-end execution mechanism, wherein the four-axis platform and the tail-end execution mechanism are electrically conductive, the four-axis platform is fixedly mounted on the top of the lifting platform, an insulation layeris arranged between the four-axis platform and the lifting platform, the four-axis platform is movable in the X, Y, and Z directions and rotatable in the Z direction, the four-axis platform is provided with an equipotential mechanism capable of establishing the equipotential relationship with the high voltage bus, the tail-end execution mechanism is detachably fastened to the four-axis platform, and the tail-end execution mechanism is provided with a bolt tightening mechanism capable of moving in the X, Y, and Z directions. The device is advantaged in that the device replaces a manual live-live working mode, can enable an operator to stay away from the high-altitude and dangerous working environment, avoid accidents such as electric shock and falling from the high altitude, can mount the high-voltage line T-type clamp through the tail-end execution mechanism in the live-live working mode, avoid the negative impact of power outages, improve power supply reliability.

Description

technical field [0001] The invention belongs to the field of electric power maintenance engineering equipment, and in particular relates to a device for installing a T-shaped clamp for a high-voltage line in live work. Background technique [0002] The high-voltage lines of the substation are densely distributed with T-shaped clamps of high-voltage lines, and their function is to divert the high-voltage lines to various cities and towns. However, since the T-shaped clamp of the high-voltage line is exposed outdoors all the year round, it is easily affected by the weather and the environment. For example, snowfall and wind will cause the high-voltage line to vibrate, causing the bolts on the connecting plate to loosen and generate electric sparks, causing a disconnection accident; at the same time The bolts on the connection plate will also be severely corroded in harsh environments, and will form bonds with the connection plate, which will easily cause accidents. Therefore,...

Problems solved by technology

This method is based on manually performing live work on the T-clamp of the high-voltage line in the equipotential state. During the work, it will be limited by the distance of the live work, making it difficult for the operator to perform the action, thus causing the bolt tightening torque to fail to meet the national standard, or even There is a situation where the wrench socket cannot cover the bolt

In addition, artificial equipotential live work must be approved by the dispatching department, and the approval process is cumbersome, making it difficult to replace loose or corroded bolts in time, increasing the risk of accidents
