Ring main units RMUs Stud welding machine Assembly line

The ring main unit stud welding machine is a specialized equipment for welding studs on the gas chamber of a ring main unit, playing a crucial role in the power supply system, especially in ring main power supply equipment that enhances the reliability of electricity supply. The ring main unit, as a core switching device, requires the front part of the gas chamber enclosure to be fixed by welding studs for the installation of insulating sleeves and operating mechanisms.

There are various control methods for stud welding machines, including simple circuit control, circuit control with voltage detection, and more advanced microcontroller intelligent control. The microcontroller intelligent control offers a user-friendly interface, convenient operation, precise charging, and is unaffected by temperature, with automatic compensation for power loss.

Energy storage stud welding does not require gas protection, is simple to operate, and is suitable for the requirements of automated production lines, widely used in automotive welding production lines. The production rate of this technology depends on the charging speed of the capacitor, with manual welding reaching 8/min and automatic welding reaching 40/min. There are two types of energy storage stud welding: lifting type and pressure type. The lifting type is suitable for welding aluminum studs and brass studs, with a welding time of about 1 millisecond; the pressure type is suitable for welding M10 and below stainless steel studs and low-carbon steel copper-plated studs, as well as M6 and below aluminum studs, and brass or copper studs, with a welding time of about 3 milliseconds.

Additionally, there is an arc stud welding machine that completes the entire welding process by discharging the welding power supply and controlling the discharge time with thyristors, with a discharge time of 5-500 milliseconds. This welding method uses microcontroller intelligent control to set and control the parameters during the welding process more accurately.

In the field of ring main unit preparation technology, there are also innovative stud welding fixtures, such as a ring main unit gas chamber stud welding fixture, which simplifies the welding process and improves work efficiency, solving the problems of high welding difficulty and low efficiency in existing technologies. This fixture includes components such as a stud positioning plate, pre-positioning pieces, and a gas chamber mounting panel, making the installation of the stud welding fixture simple, greatly improving welding efficiency, and making installation and disassembly more convenient.

Furthermore, there is a gas-insulated ring main unit gas chamber stud welding fixture, which fixes the position of the gas-insulated ring main unit main body, then accurately adjusts the position of the gas chamber close to the welding position of the gas chamber on the main body, facilitating welding operations for workers, reducing labor, improving the accuracy of welding operations, and effectively improving the production and processing efficiency and quality of gas-insulated ring main units. This fixture includes a welding base, a gas chamber placement table, and a clamping plate base, etc., achieving precise position adjustment and efficient welding through the use of telescopic cylinders, a rotating worktable, and positioning rulers, etc.
