Problems solved by technology
In the daily 27.5kV isolating switch assembly process, due to the lack of a systematic production system, each process can only be carried out step by step when assembling the isolating switch, which is time-consuming and laborious, and the production and assembly efficiency is low. Therefore, it is urgent to design a 27.5kV The production system assembled by kV isolating switch improves the efficiency of production and assembly

The invention discloses a production system suitable for 27.5 kV isolating switch assembly, which comprises two groups of fixed bracket assemblies, a plurality of groups of switch mounting trolleys, a movable bracket assembly, two groups of movable bracket trolleys and two groups of movable bracket positioning channel steels; the fixed bracket assemblies are fixed with the ground, and the switch mounting trolleys are placed on the fixed bracket assemblies to freely slide; the disconnecting switch is installed on a positioning hole reserved in the switch installation trolley, the movable bracket assembly is arranged between the two fixed bracket assemblies, and the movable bracket assembly and the two fixed bracket assemblies are connected in a fastened mode through the movable bracket positioning channel steel to form production equipment. The two groups of movable bracket trolleys are placed on the movable bracket assembly to freely slide, so that another isolation switch assembly production equipment formed by mounting in different procedures is formed. The beneficial effects of the invention are that simultaneous and ordered operation of all procedures is achieved during the assembly, so that the system saves a large amount of time, and effectively improves the work efficiency of a workshop worker during the assembly of the disconnecting switch.
Description
technical field [0001] The invention belongs to the technical field of high-voltage electrical equipment, and in particular relates to a production system suitable for assembling 27.5kV isolating switches. Background technique [0002] High-voltage isolating switch is the core component of power supply equipment in electrified railway system, and plays a very important role in modern railway transportation system. Its main function is to cut off the live part of the line from the part that needs to be powered off during the equipment maintenance of the railway power supply line, and ensure an effective safe distance, so as to ensure the personal safety of the staff during equipment maintenance. According to the different voltage levels, it can be roughly divided into GN2-27.5kV, GW4-27.5kV, GW4-126kV, GW4-252kV, and GW7-252kV types. Among them, the 27.5kV series isolating switch is widely used in railway catenary power supply and In the substation power supply system, the m...
