An installation method and auxiliary adjustment tool for a closed busbar

Abstract

The invention discloses a method for installing an enclosed busbar and an auxiliary adjusting tool. The auxiliary adjusting tool is employed as a rigid support, which makes it easy to transport enclosed busbar pipe joints to other sites, and conduct detection and adjustment and also fitting-up and welding on the enclosed busbar pipe joints. Large amount of high altitude constructions are plumbed to ground horizontal construction, which meets high precision for installation and adjustment of the enclosed busbar. Simultaneous lifting of a permanent supporting crossbar and a temporary crossbar is employed, which helps to realize precise and safe lifting and installation of the entire three-phase busbar. According to the invention, the method and the auxiliary adjusting tool reduce large-area bent and air welding platform establishing, reduce safety hazards in construction, shorten installation construction period, and have the advantages of being economical, practical, and efficient.

Description

technical field [0001] The invention relates to the field of equipment installation, in particular to an installation method of a closed busbar and an auxiliary adjustment tool. Background technique [0002] The power station generator and the main transformer are usually connected by an isolated closed busbar, and the underground powerhouse often arranges the closed busbar in a dedicated busbar cavern at the same elevation as the generator floor. Closed busbars are often installed in the air to save space. Due to the height of the cavern and the installation space, large lifting equipment such as bridge cranes and cranes cannot enter the busbar cavern. The traditional method is to set up temporary bent frames and platforms, and install permanent supports first. For beams, single-section busbars are hoisted into the air one by one, butt joints are adjusted and welded. A large number of high-altitude operations make it difficult to ensure installation accuracy, high operating...

Problems solved by technology

Closed busbars are often installed in the air to save space. Due to the height of the cavern and the installation space, large lifting equipment such as bridge cranes and cranes cannot enter the busbar cavern. The traditional method is to set up temporary bent frames and platforms, and install permanent supports first. For beams, single-section busbars are hoisted into the air one by one, butt joints are adjusted and welded. A large number of high-altitude operations make it difficult to ensure installation accuracy, high operating risks, and low installation efficiency. Therefore, how to install busbars efficiently and with high quality has always question in mind
