Equipment functions and practical features
1. Continuous and stepless adjustment of current, both small current terminals and large-sized busbars can be tested using the same equipment;
2. Multi channel thermocouples synchronously collect temperature data and monitor the temperature rise curve of the test sample in real-time at multiple points;
3. Preset the duration of the national standard temperature rise test, and automatically reduce the current and stop the machine when the set time is reached, without the need for manual supervision;
4. The current rise process is smooth without any impact current, avoiding instantaneous high current damage to the conductive contact surface of the test sample;
5. Air cooled cooling structure, with controllable body temperature for long-term full load testing, suitable for batch continuous testing.
Application Scenarios
1. High and low voltage switchgear factory: Batch testing of temperature rise of finished circuit breakers and bus ducts before leaving the factory;
2. Copper bar processing enterprises: high current busbar current carrying and heating performance testing;
3. Third party testing of power equipment: Temperature rise items for switchgear and isolating switch type tests;
Precautions
1. When opening the box, the electrical components and contact points should be checked for any transportation damage or poor contact.
2. Before use, check whether the contact of each electrical appliance is good, especially the contact of the voltage regulator carbon brush must be good.
3. Strictly follow the relevant operating procedures and strictly prohibit unauthorized use or use without the supervision of a safety officer.
4. The equipment should be stored in a well ventilated, dry, and non corrosive gas environment.
