Test Bench for Medium-Voltage Switchgear Drives


Test bench for the mechanical testing of medium-voltage drives

task

Development and construction of a mechanical test rig for carrying out functional and load tests on medium-voltage drives.

The test rig was designed for flexible use in a variety of test scenarios and for small production runs. In addition to the mechanical design, particular emphasis was placed on ensuring that manual testing and loading procedures could be carried out safely.

Technical requirements

The design of the test bench was largely determined by the following constraints:

  • Small production runs: Due to the limited production volumes, a conscious decision was taken not to implement extensive automation.
  • High level of operator interaction: Loading and unloading, as well as various test steps, are carried out manually and require the test bench to be ergonomically designed.
  • Increased risk potential: High forces are generated during mechanical testing. The safety concept therefore had to take particular account of the need to protect operating personnel from crush injuries, impact injuries and other mechanically caused injuries.
  • Versatile application: The test bench was designed to be portable and versatile, and is mounted on a sturdy workbench.
  • Robust construction: The mechanical components have been designed to withstand the loads they are subjected to and are built to withstand repeated test cycles.

Our services

As part of the project, we were responsible for the complete technical implementation of the test bench:

  • Design and production of technical drawings
  • Preparation of electrical circuit diagrams and design documentation
  • Development and implementation of the security plan
  • Carrying out the risk assessment and drawing up the necessary CE conformity documentation in accordance with the Machinery Directive
  • Selection and procurement of the necessary components
  • Organisation of the manufacture of mechanical components via our manufacturing network
  • Mechanical assembly and electrical installation
  • Commissioning and quality control

Result

The result is a compact and robust test rig that enables the mechanical testing of medium-voltage drives under defined conditions. The combination of manual operation, flexible positioning and a safety concept tailored to the mechanical forces involved ensures cost-effective operation even for small production runs.
