Description

Maintenance platform

technical field

The utility model relates to a support tool for installation and maintenance of current transformers in the electric power industry, specifically a maintenance platform.

Background technique

The main reason for the long disassembly and assembly time in the current transformer replacement operation in the existing electric power industry is that due to the limitation of the working space during the maintenance process, the current transformer must be supported by manpower during the operation to complete the replacement operation. In this way, multiple people are required to perform the replacement operation every time a current transformer is replaced, and during the operation, a maintenance personnel supports the current transformer manually for up to 40 minutes. It can be seen that replacing the three current transformers is a great challenge and test for the physical strength and endurance of the maintenance personnel. Such a time-consuming and laborious operation process reduces our maintenance efficiency, the maintenance time is longer, and the corresponding power outage time becomes longer. , affecting people's life and the company's production; because the workers' operation is more laborious during the replacement, in order to pay close attention to the installation, sometimes the installation requirements cannot be met, and the accuracy is reduced, so it is necessary to develop a tool to play a role in installing and replacing the transformer. The purpose of saving time and labor and high installation accuracy is achieved.
