Customer Case: Switchgear Gas Tank Testing, Helium Leak Detection, Welding Room and Handling Automation Line

switchgear gas tank helium leak testing station

Project Overview

This customer case presents a practical automation solution for medium-voltage switchgear and ring main unit gas tank manufacturing. The project covers mechanical characteristic and loop resistance testing, pneumatic balancing lifting, gas tank helium leak detection, offline lifting after leak testing, a controlled gas tank welding room, and automatic stud welding for gas tank sheet metal parts. These units are production tools designed to make the manufacturing process safer, more repeatable, easier to inspect, and more credible for overseas buyers.

For manufacturers of ring main units, gas insulated switchgear, compact substations, and power distribution equipment, the gas tank is a critical component. It must support structural accuracy, sealing reliability, pressure resistance, stable assembly, and long-term field performance. A small process variation in welding, handling, leak testing, or electrical inspection may create rework, delivery delay, or quality risk.

Challenges Before the Upgrade

Before the upgrade, the customer faced several typical challenges. Heavy or position-sensitive gas tank components had to be moved between different work areas. Operators needed to align parts manually, connect test cables, adjust tooling, and record results. Different product models required different fixtures and different handling methods. The production flow was workable, but it depended too much on skilled workers and informal experience.

Mechanical Characteristic and Loop Resistance Testing Station

The mechanical characteristic and loop resistance testing station is used for outgoing inspection of circuit breaker mechanisms, switchgear modules, and related electrical components. In medium-voltage switchgear production, stable movement performance and loop resistance data are important acceptance indicators. A professional testing station organizes workpiece positioning, cable routing, operation, observation, recording, and maintenance into a repeatable process. For export-oriented factories, this visible inspection process helps explain quality control to overseas buyers and supports stronger supplier evaluation documents.

Pneumatic Balancing Lifting Machine

The pneumatic balancing lifting machine supports safer transfer of gas tanks, cabinet structures, welded parts, and assembly modules. The value is not limited to lifting heavy objects. In switchgear gas tank manufacturing, many parts require stable posture, protected surfaces, and precise placement between stations. Yufeng evaluates product weight, size range, pickup direction, station layout, takt requirement, and worker position before designing the gripper and guiding structure. This reduces manual handling, surface damage, and repeated repositioning.

Gas Tank Helium Leak Testing Station

Helium leak testing is a key quality checkpoint for gas insulated switchgear and ring main unit gas tanks. Sealing reliability affects long-term operation, customer acceptance, and field service risk. A good helium leak testing station must balance detection accuracy, operation speed, and maintenance convenience. If the customer wants future traceability, the station can reserve interfaces for barcode scanning, test result storage, and quality data export.

Offline Lifting After Helium Leak Testing

After leak testing, the qualified gas tank still needs to move to assembly, buffering, or packaging. The offline lifting machine keeps the transfer stable and prevents the testing station from becoming a bottleneck. Yufeng plans the lifting device together with the testing equipment, buffer area, logistics route, and operator space so the station remains efficient and easy to use.

Controlled Gas Tank Welding Room

The gas tank welding room provides a more controlled and manageable environment for welding operations. Gas tank welding requires attention to weld quality, deformation control, fixture accuracy, ventilation, lighting, safety, and maintenance access. It can also reserve space for future robotic welding, electrical interfaces, air supply, safety fencing, and control cabinets.

Automatic Stud Welding Machine for Gas Tank Sheet Metal

The automatic stud welding machine improves consistency in the sheet metal preparation stage. Stud position, quantity, and welding quality influence later assembly efficiency and product stability. An automatic system can use a defined platform, programmable path, stable welding parameters, and repeatable positioning. For factories with several gas tank models, fast model change and parameter storage are important.

Integrated Production Logic

The value of this project comes from integration. Mechanical testing, loop resistance testing, helium leak detection, lifting, welding, and stud welding are connected by one manufacturing logic: stable positioning, safer handling, repeatable inspection, better process control, and stronger factory presentation. Each equipment unit solves a specific problem, but together they create a stronger production system for switchgear gas tank manufacturing.

Value for Overseas Buyers

Overseas buyers searching for a custom automation equipment manufacturer, switchgear assembly line supplier, RMU production line partner, or gas tank helium leak testing solution need evidence. They need to know whether the supplier understands the product, not only the machine. This customer case provides that evidence through real equipment categories and practical manufacturing details.

FAQ

Can this solution be purchased step by step?

Yes. A customer can start with the station that creates the most pressure, such as helium leak testing, lifting, or welding process control, and then expand to a more complete line.

What information is needed for a similar project quotation?

The buyer should provide product drawings, sample photos, weight range, annual output, target cycle time, current process videos, workshop layout, quality standards, and expected delivery schedule.
