High Current Temperature Rise Test Equipment for Electrical Contact Resistance

Product Overview

The High Current Injection and Temperature Rise Testing System is developed for evaluating the thermal performance of electrical equipment under specified current loading conditions. Combining adjustable high-current output, digital measurement, multi-channel temperature acquisition, and intelligent test management, it provides a practical solution for electrical product testing and quality verification.

Advantages

1. Consistent Current Loading
   A high-capacity voltage regulator and high-permeability magnetic core transformer form the basis of the current output system. The output can be adjusted according to the selected equipment configuration and required test conditions.
2. Detailed Thermal Data Collection
   With selectable 12-, 24-, 48-, or 64-channel temperature acquisition, the system allows multiple locations to be monitored during the same test. This supports comparison of temperature changes across terminals, busbar joints, conductive connections, and other test points.
3. Clear Digital Test Monitoring
   The digital control interface provides access to key electrical measurements, temperature readings, and timing information, helping operators observe test progress and maintain consistent records.
4. Automatic Test Data Processing
   Automatic curve generation and standardized report generation help organize test results for technical review, product comparison, and quality documentation.
5. Flexible Operating Modes
   Manual and automatic operation modes accommodate different test procedures, from operator-controlled experiments to more standardized testing workflows.

FAQ

1. What is the difference between high-current injection testing and temperature rise testing?
   High-current injection testing applies a specified current to an electrical device for a defined purpose. Temperature rise testing focuses on monitoring and evaluating the resulting temperature changes under specified test conditions. The same system may support both applications when properly configured.
2. Can this system test circuit breakers and switchgear?
   It is designed for high-current and thermal testing of electrical equipment, including circuit breakers, switchgear, busbars, and related components. Suitability depends on the required current, voltage, test duration, and applicable test procedure.
3. Can multiple temperature points be measured simultaneously?
   Yes. The available configurations include 12, 24, 48, and 64 temperature measurement channels.
4. Is continuous operation supported?
   Continuous operating capability depends on the rated current, duty cycle, cooling design, and load conditions. Please specify the current and required test duration so that the operating capability can be confirmed.
5. Does the system support customized configurations?
   Yes. Output ratings, temperature measurement channels, cabinet structure, and control requirements can be discussed according to the intended application.
