The invention discloses an installation process and equipment for a high-voltage switchgear, which includes unpacking inspection, checking the specifications and models of the equipment body, accessories, and spare parts according to the equipment packing list; checking product qualification certificates, technical materials, and instructions; Hoisting to the transportation equipment, the transportation equipment moves the high-voltage switchgear to the designated position; the solid phase change block is placed under the high-voltage switchgear, and the transportation equipment is removed from the high-voltage switchgear; the phase change block changes from solid to liquid, and the high-voltage switchgear The height of the cabinet is gradually reduced until it touches the foundation steel; the switch cabinet is installed, and the high-voltage switch cabinet is placed in order according to the layout of the construction drawing. The invention has the effect of stably contacting the high-voltage switchgear with the basic section steel.
Description
technical field [0001] The invention relates to the field of high-voltage switchgear installation methods, in particular to a high-voltage switchgear installation process and equipment. Background technique [0002] High-voltage switchgear refers to equipment used for on-off, control or protection in power system generation, transmission, distribution, power conversion and consumption. [0003] At present, the installation method of the high-voltage switchgear is usually to place the high-voltage switchgear on the roller bar, push it manually, and use a crowbar to pry the switchgear into place, which may cause personal injury, The equipment is damaged, which cannot meet the construction requirements of lean substations. At the same time, the construction efficiency is low and a lot of manpower and material resources are wasted. [0004] The Chinese invention patent with the authorized notification number CN105870824B discloses a high-voltage switchgear positioning device, i...
