Abstract
The utility model relates to a portable unequal-diameter insulation operating rod, which comprises a plurality of insulation rod segments sequentially connected. The top end of the upmost insulation rod segment is provided with a top member, the insulation rod segments are connected via connection members, and each insulation rod segments is a hollow rod with foam filled inside. According to the portable unequal-diameter insulation operating rod, characteristics of portability and convenient installation of an original insulation operating rod are kept; besides, the structure is more reasonable and the assembly is more flexible; and the portable unequal-diameter insulation operating rod can be applied to 750kV electric transmission lines.
Description
Technical field
The utility model belongs to the high-voltage electric device field, relates to a kind of insulating bar, the insulating bar that especially a kind of power industry ultra-high-tension power transmission line uses, and it is applicable to the 750kV electric pressure.
Background technology
750kV electric pressure network is not long in electric power system time of putting into operation, in the gradually expansion (comprising the work such as live line working) of work that the 750kV transmission line is carried out, needs exploitation and improve to be fit to the Work tool that uses.
Because the 750kV electric pressure is higher, the safe insulation of requirement distance is larger, be on the form basis of the insulating bar that original low voltage grade is used, and transform to develop and be adapted at the insulating bar that uses on the 750kV transmission line.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, a kind of portable not isometrical insulating bar is provided, the characteristics that this action bars had both kept the insulating bar of prior art to be easy to carry and to install, can satisfy again the 750kV electric pressure high, the requirement of line insulation size large (or far), and its structure distribution is more reasonable, assembles more flexible.
The purpose of this utility model solves by the following technical programs:
This portable not isometrical insulating bar comprises the some sections insulating bar sections that connect successively, is provided with top part on the top of the insulating bar section of the top, connects by link between each insulating bar section; Described each insulating bar section is the inner frothy hollow stem of filling.
Above-mentioned top part is the tubular cap that is set in insulating bar section top, the top, is provided with binaural connector in tubular cap upper end, offers through hole at binaural connector.
Above-mentioned link is comprised of sleeve member and insert; Described sleeve member is set in the front end of each insulating bar section, and described insert is connected to the tail end of each insulating bar section.
Above-mentioned sleeve member is comprised of cylinder cap, the cylinder cap connector that is connected to a cap rear end and the connecting cylinder that is set on the cap connector.
Portable not isometrical insulating bar of the present utility model both kept original insulating bar to be easy to carry and the characteristics of installing outside, make again its structure distribution more reasonable, assemble more flexible.Be adapted at using on the 750kV transmission line.

Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1 and Fig. 2, portable not isometrical insulating bar of the present utility model comprises the some sections insulating bar sections 1 that connect successively, is provided with top part 2 on the top of the insulating bar section 1 of the top, connects by link between each insulating bar section 1; Each insulating bar section 1 is the inner frothy hollow stem of filling.Described link is comprised of sleeve member 3 and insert 4; Sleeve member 3 is set in the front end of each insulating bar section 1, and insert 4 is connected to the tail end of each insulating bar section 1.
As shown in Figure 3: top part 2 is provided with binaural connector 2.2 for being set in the tubular cap 2.1 on insulating bar section 1 top, the top in tubular cap 2.1 upper ends, offer through hole 2.3 at binaural connector 2.2.
As shown in Figure 4: sleeve member 3 is comprised of cylinder cap 3.1, the cylinder cap connector 3.2 that is connected to a cap 3.1 rear ends and the connecting cylinder 3.3 that is set on the cap connector 3.2.
In most preferred embodiment of the present utility model, for guaranteeing effective insulation property of insulating tool, adopt the insulating material (expoxy glass fiber tube add internal foam filling) identical with the insulating bar that uses on other electric pressure, as main insulating material, each section link adopts stainless steel material.In order to be applicable to 750kV, insulating bar integral body is divided into six sections, and every segment length is about 1.8 meters (every section effective insulated lengths is 1.73 meters), and wherein: near 1 section, 2 sections, 3 sections of high-pressure sides (front end), the outer warp of bar is Φ 30mm; Near 4 sections, 5 sections, 6 sections of handheld terminals (rear end), the outer warp of bar is Φ 32mm.Every section insulating bar thickness of pipe 2mm, internal foam is filled, and six sections connect rear whole total length by the stainless steel link and are about 10.8 meters.
