What is a Load Isolation Switch Automatic Testing Line?<\/h2>\n

An automated load isolation switch testing machine is a special testing machine that will check the electrical and mechanical operation of low voltage load break switches and disconnectors in power distribution. Load break switch and disconnectors must comply with high standards for safety and reliability (IEC 60947-3, GB\/T 14048.3). Our automated tests are made up of up to ten sequential test stations: visual inspection; dimensional verification; mechanical stroke and operating torque measurement; contact resistance (micro-ohm) testing; dielectric withstanding (Hi-Pot) testing; temperature rise at rated current; electro-mechanical endurance (operating life); auxiliary contact\/interlock verification; final ON\/OFF verification; coding\/traceability. The testing machine uses servo actuators with high precision, programmable current sources; data is collected in real time. The recorded data is sent to MES for total traceability and SPC analysis. As a custom solution, the load isolation switch machine may be engineered specifically for your switch design, current rating (e.g., 16A-630A), pole configurations, and test specifications.<\/p>\n

Detailed 10\u2011Step Test Process<\/h2>\n
\n

The automated test line executes the following sequence:<\/p>\n

    \n
  1. Material loading<\/strong> \u2013 Automatic conveyor or robot loading of switches into test fixtures.<\/li>\n
  2. Appearance & dimensional inspection<\/strong> \u2013 Vision system checks for missing parts, deformation, and critical dimensions.<\/li>\n
  3. Mechanical motion \/ stroke & torque inspection<\/strong> \u2013 Measures operating force, stroke angle, and ON\/OFF torque.<\/li>\n
  4. Contact resistance \/ continuity test<\/strong> \u2013 Loop resistance measurement (\u226450\u03bc\u03a9) using 100A DC.<\/li>\n
  5. Insulation \/ withstand voltage (hi\u2011pot) test<\/strong> \u2013 Applies AC high voltage between phases and phase\u2011to\u2011ground; detects leakage.<\/li>\n
  6. Rated current \/ temperature rise test<\/strong> \u2013 Passes rated current for a defined period, monitors temperature increase.<\/li>\n
  7. Operating life \/ electromechanical durability test<\/strong> \u2013 Performs up to 10,000 mechanical cycles with real\u2011time monitoring.<\/li>\n
  8. Auxiliary \/ additional function test<\/strong> \u2013 Verifies auxiliary contacts, locking\/interlocking mechanisms.<\/li>\n
  9. Final function confirmation<\/strong> \u2013 Checks ON\/OFF indication and proper switching.<\/li>\n
  10. Coding \/ traceability + packaging inspection<\/strong> \u2013 Laser marking of serial number, barcode scanning, and final visual check before packaging.<\/li>\n<\/ol><\/div>\n

    \n
    \n

    High\u2011speed parallel & sequential testing<\/h4>\n

    The line is designed with multiple independent test stations that operate concurrently where possible (e.g., contact resistance, hi\u2011pot, mechanical life). This minimizes idle time and achieves a total cycle time of \u226428 seconds per unit.\n <\/p><\/div>\n

    \n

    Precision loop resistance measurement<\/h4>\n

    The loop resistance station uses a 100A DC test current (IEC 60947\u20113 requirement) with a four\u2011wire Kelvin connection, achieving \u00b12% accuracy. This ensures reliable detection of loose connections or undersized conductors.\n <\/p><\/div>\n

    \n

    Automated mechanical endurance with torque recording<\/h4>\n

    A servo actuator performs up to 10,000 ON\u2011OFF cycles at programmable speed and stroke. An integrated torque sensor records the operating force curve, identifying wear or binding before failure.\n <\/p><\/div>\n

    \n

    Full MES traceability for export certification<\/h4>\n

    Each test result (including raw curves for torque, temperature, and contact resistance) is linked to the unit\u2019s barcode. The system generates electronic test reports compliant with export certification requirements (e.g., CE, UL, IEC). SPC dashboards provide real\u2011time quality visibility.\n <\/p><\/div>\n<\/p><\/div>\n
