    Product Detail

    Equipment Overview

    The Thermal Relay Delay Characteristic Test Bench is a specialized testing system used to evaluate the overload delay protection characteristics of thermal overload relays.
    Thermal relays play a critical role in motor protection by responding to prolonged overload conditions with a defined time delay, preventing motor damage caused by overheating.

    This test bench simulates continuous overload currents and precisely measures the tripping time of thermal relays under specified current multiples. It supports various relay types, current ranges, and trip classes, enabling accurate verification of relay performance.

    The system integrates stable current injection, precise timing measurement, and automated data recording, ensuring reliable and repeatable results. It fully complies with IEC 60947-4-1, making it suitable for production testing, quality control, and type testing laboratories.

    System Configuration

    The test bench typically consists of the following systems:

    • 🖥️ Control System Equipped with an advanced control system and intuitive operation panel, allowing flexible setting of fault modes, test current, and delay time parameters.
    • ⚡ Power Supply System Provides stable and adjustable voltage and current output to meet the testing requirements of different types and ratings of circuit breakers.
    • ⚠️ Fault Simulation System Simulates various fault conditions, including overload, short circuit, and grounding, with precise control of fault current and delay time.
    • 📊 Data Recording System Automatically records key parameters such as operating time, fault current, and delay cut-off time, generating clear and traceable test data for analysis and evaluation.
    • 🛡️ Safety Protection System Integrated with multiple safety protections, including overload, over-temperature, and short-circuit protection, ensuring safe operation during testing.
