Installation Tool for Switchgear Suspension Current Transformer

Abstract

The invention discloses a switch cabinet suspension type current transformer mounting tool. The mounting tool can automatically and flexibly ascend or descend in a narrow space, multi-angle fixed transformers can be stabilized in the working process, and one-person individual operation can be achieved. The mounting tool comprises a base assembly; a height adjusting assembly used for height adjustment is mounted on the base assembly; a lifting platform assembly is mounted on the height adjusting assembly; a rotary rail assembly is mounted on the lifting platform assembly; an inclined angle adjusting assembly used for adjusting an inclined angle relative to the horizontal plane is rotationally mounted on the rotary rail assembly; the height adjusting assembly comprises at least two groups ofX brackets hinged and mounted in the height direction; the lifting platform assembly is mounted on the X bracket at the top; the rotary rail assembly comprises a fixed inner ring fixedly mounted on the lifting platform assembly; a rotating outer ring is rotationally mounted outside a fixed inner cavity; the inclined angle adjusting assembly is mounted on the rotating outer ring, and comprises a bottom plate at the bottom; and two groups of expansion brackets of the same structure are mounted on the bottom plate.

Description

technical field [0001] The invention relates to a current transformer installation tool, which is particularly used for the installation, disassembly and maintenance of a switch cabinet suspension type current transformer. Background technique [0002] As the most important primary equipment of the substation, the current transformer is of great significance to the power system. Its safe and stable operation is of great significance to the power system. During the maintenance or replacement of the current transformer, due to the small space inside the switch cabinet, only one person can enter, and the installation is very laborious. In addition, a group of transformers are continuously replaced, and a single person is physically exhausted, and at least three people are required to work in rotation. The staff can only lie down or squat in a narrow space to hold up and install the current transformer, which brings great hidden danger to the personal safety of the staff and is ...

AI Technical Summary

Problems solved by technology

[0005] 1. The installation heights of different transformers in the cabinets of various manufacturers are not consistent

[0006] 2. Inconsistent layout design of the equipment in the cabinet leads to uneven design of the bottom of the cabinet of some manufacturers

[0007] 3. At present, sleepers are mostly used for installation, and it takes a long time to install due to the uneven cabinet space, height and bottom surface

The results of the novelty search show that the functions of the existing devices are significantly different from the subject of our research
