Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of guide rails, and more specifically to a reinforced guide rail for a 12kV switch cabinet. Background Art
[0002] A guide rail (VAVguide) is a device with grooves or ridges made of metal or other materials that can bear, fix, guide moving devices or equipment and reduce their friction. A guide rail, also known as a slide rail, linear guide rail, or linear slide rail, is an upgraded version of a linear bearing bracket used in linear reciprocating motion. It has a higher rated load than traditional linear bearings and can bear a certain torque. It can achieve high-precision linear motion under high load conditions. The longitudinal grooves or ridges on the surface of the guide rail are used to guide and fix linear bearings and other machine parts, special equipment, instruments, etc.
[0003] The shortcomings of the existing technology: At present, the guide rails for 12kV switch cabinets are usually made of aluminum alloy profile guide rails and iron guide rails. The positioning front ends of these two guide rails are designed as a rectangular structure with a length of 16mm×width of 3mm×thickness of 9mm, and the rectangular structure is inserted into the 20mm×3.2mm positioning hole of the contact box mounting plate 2.2. The strength of these two guide rail structures does not meet the requirements of the switch cabinet with a rated peak withstand current of 160kA. The melting point of aluminum alloy is about 650°, and the melting point of Q235 steel is about 1493°. The aluminum alloy profile guide rail has obvious disadvantages. For this reason, we propose a reinforced guide rail for 12kV switch cabinets. Utility Model Content
