Description

Replacement device for supporting insulators

technical field

The utility model relates to the technical field of electric power construction, in particular to a replacement device for supporting insulators.

Background technique

At present, in open substations, the busbars with a voltage level above 110KV mostly use exposed tubular busbars, and the busbars are installed on fixed devices. Porcelain insulators are generally used for fixing devices, and porcelain insulators are usually called bus support insulators or bus support bottles. Porcelain insulators not only fix the busbar but also play the role of insulation. After the busbar support insulator is installed outdoors and has a long service life, the firmness and insulation strength of the busbar support insulator will decrease to a certain extent. In order to ensure the reliable and safe operation of the busbar, the supporting insulators of the busbar need to be replaced regularly.

In the prior art, in the process of replacing the supporting insulators of the busbars, considering that the busbars are deformed due to the loss of the support of the supporting insulators of the busbars, it is usually necessary to add an additional crane on site to support the busbars. If the safety distance between the crane and the adjacent live equipment does not meet the requirements, it is necessary to additionally cut off the adjacent equipment on the basis of a power outage on the bus, which expands the scope of the power outage and adds a lot of cumbersome operations.

In order to achieve the above object, the utility model provides a replacement device for supporting insulators, including: a frame; a boom, including a first boom matched with the busbar and a second boom matched with the supporting insulator, the first boom and Both booms are mounted on the frame.

Further, the frame includes a plurality of columns and a plurality of beams, at least one beam is arranged between two adjacent columns, and the boom is installed on the beams.

Further, the beam and the column are connected by welding.

Further, there are three beams between two adjacent columns, and the boom is detachably mounted on the three beams.

Further, the boom includes a vertical section, a horizontal section and an arc section, the horizontal section and the vertical section are connected through the arc section, and the vertical section is detachably connected to the beam.

Since the replacement device occupies a relatively small space, it satisfies the safety distance of live equipment in terms of safety, and effectively avoids damage to live equipment such as busbars. During the replacement process, only the busbars supported by the old supporting insulators need to be powered off, which greatly reduces the scope of power outages and the number of additional switching operations and corresponding time. In this way, the old support insulator can be hoisted smoothly, and then the new support insulator can be hoisted up, and the first boom is still supporting the busbar during the replacement process. During the replacement process of the bus support insulator, the work efficiency is improved, the scope of power outage is reduced, and the risk caused by too many power outage equipment to the power grid is reduced.
