Problems solved by technology

[0002] Most of the old ordinary insulators used in 35KV and above substations need to be replaced with anti-pollution insulators, but this replacement requires a lot of work, and the power outage time of the equipment is short during the replacement process. The requirements are relatively high, but because the construction site of the substation is complex, there are many live equipment, and the working range is small, and the current single-piece fixture not only increases the labor intensity, reduces the work efficiency, but also requires a power outage during installation longer time

Embodiment Construction

[0008] exist figure 1 Among them, the present invention is a complete set of tools for replacing the strain-resistant insulator strings of the substation structure. Several horizontal bars 7 and longitudinal bars 8 are insulated epoxy resin tubes, and the horizontal bars 7 and longitudinal bars 8 are connected to the metal bracket 6 to form a stretcher shape, and the insulator strings are placed on the bottle rack. The two ends of the bottle holder are respectively equipped with a movable fixture 2 and a fixed fixture 3, the movable fixture 2 is an angle iron, and the fixed fixture 3 is a galvanized round steel, and the bottle holder is located on both sides of one end of the fixed fixture 3 There are ratchet hand hoists 4 respectively. The ratchet hand hoists 4 are 3T ratchet hand hoists. The two ratchet hand hoists 4 are connected with the movable fixture 2 by tightening the rope 5. The two ratchet hand hoists 4 drive the movable fixture 2 by tightening the rope 5. Movement...

Abstract

The invention discloses a tool set for replacing a strain insulator string of a substation framework. The tool set is provided with an insulator cradle, wherein the insulator string is placed on the insulator cradle, the two ends of the insulator cradle are provided with a movable clamp (2) and a fixed clamp (3) respectively, the two sides, arranged at one end of the fixed clamp (3), of the insulator cradle are respectively provided with a ratchet lever pulley block (4), the two ratchet lever pulley blocks (4) are connected with the movable clamp (2) through a tightening rope (5), and the two ratchet lever pulley blocks (4) drive the movable clamp (2) to move through the tightening rope (5). According to the tool set, the power outage time can be greatly shortened, the labor intensity can be reduced, and the labor efficiency is improved.

Description

technical field [0001] The invention relates to a complete set of tools for replacing the tension insulator strings of substation structures. Background technique [0002] Most of the old ordinary insulators used in 35KV and above substations need to be replaced with anti-pollution insulators, but this replacement requires a lot of work, and the power outage time of the equipment is short during the replacement process. The requirements are relatively high, but because the construction site of the substation is complex, there are many live equipment, and the working range is small, and the current single-piece fixture not only increases the labor intensity, reduces the work efficiency, but also requires a power outage during installation The time is relatively long. Contents of the invention [0003] The invention provides a complete set of tools for replacing the strain-resistant insulator strings of the substation structure, which not only can greatly shorten the power ...
