Problems solved by technology

[0002] At present, insulation ladders are usually used in substation maintenance operations, but due to the narrow indoor space, it is difficult to place the existing standard insulation ladders behind the pipe busbars, and the surrounding space cannot place the insulation ladders in the working area of ​​the wall bushing , the insulation ladder can only be placed by multiple people after lifting the standard insulation ladder from the pipe bus, which is not only laborious and inconvenient to use, but also consumes manpower, increases power outage time, and causes power loss

Embodiment Construction

[0023] Such as Figure 1-Figure 2 As shown, the present invention relates to a substation indoor segmented insulation ladder, which is formed by sequentially connecting a multi-section combined lower ladder 1 and a single combined upper ladder 7 made of insulating materials to form a right-angled trapezoid. The combined ladder 1 includes an inclined ladder 2 arranged obliquely and a flat ladder 5 arranged horizontally. The inclined ladder 2 and the flat ladder 5 are respectively composed of two main pipes 3 and a plurality of pipes evenly distributed between the two main pipes 3. The cross bar 14 is formed, wherein the upper ends of the two main pipes 3 of the inclined ladder 2 and the outer ends of the two main pipes 3 of the flat ladder 5 are detachably connected by insulating clips 4, and the two main pipes 3 of the flat ladder 5 are kept away from the inclined ladder 2 by one Two branch pipes 11 are connected laterally symmetrically, and the upper ends of the two branch pi...

Abstract

The invention discloses an indoor sectional insulating ladder for a transformer substation. The indoor sectional insulating ladder is formed by sequentially connecting multiple combining lower ladders and a combining lower ladder, each combining lower ladder comprise an inclined ladder and a horizontal ladder, the upper ends of two main pipes of each inclined ladder are detachably connected with the outer ends of two main pipes of the corresponding horizontal ladder, two branched pipes are symmetrically connected on the main pipes of each horizontal ladder, horizontal distances from joints of the horizontal ladders and the inclined ladders to joints of the horizontal ladders and the branched pipes of the combining lower ladders from bottom to top sequentially decrease, a connecting sleeve is arranged on the lower portion of each of the main pipes and the branched pipes of each inclined ladder in a sleeved manner, and adjacent combining lower ladders are in mutual inserted connection through the main pipes and the branched pipes of the inclined ladders and locked through the connecting sleeves. The indoor sectional insulating ladder has the advantages that the indoor sectional insulating ladder can be assembled freely according to actual conditions in the transformer substation, can be assembled in various heights and is especially suitable for being mounted in narrow space for working; working safety of maintenance personnel can be ensured; the indoor sectional insulating ladder is quick, convenient, time saving and labor saving in demounting and mounting, so that operating efficiency can be improved, manpower can be saved, outage time can be shortened, and power loss can be reduced.

Description

technical field [0001] The invention relates to an insulating ladder, in particular to an indoor sectioned insulating ladder of a substation. Background technique [0002] At present, insulation ladders are usually used in substation maintenance operations, but due to the narrow indoor space, it is difficult to place the existing standard insulation ladders behind the pipe busbars, and the surrounding space cannot place the insulation ladders in the working area of ​​the wall bushing , the insulation ladder can only be placed after lifting the standard insulation ladder from the pipe busbar by multiple people, which is not only laborious and inconvenient to use, but also consumes manpower, increases power outage time, and causes power loss. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a substation indoor segmented insulating ladder which is easy to operate, saves time and effort, can save manpower, shorten pow...
