AC Contactor Comprehensive Characteristic Test Bench
Equipment Overview
The AC Contactor Comprehensive Characteristic Test Bench is a multifunctional testing system used to evaluate the overall performance characteristics of AC contactors under various operating conditions.
It enables comprehensive verification of pickup and dropout voltage, operating time, contact resistance, electrical endurance, mechanical life, and temperature rise, ensuring that contactors meet both safety and performance requirements.
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.
