Adjusting device life
Simulate the frequency and amplitude of normal use, and then evaluate the strength of the regulating device/electrical mechanical connection, whether the insulation of the internal wiring is damaged, the degree of conductor fracture, and the voltage drop in the conductor
The lifespan test of regulating devices is an experimental method that simulates normal usage conditions to evaluate the durability, reliability, and safety of regulating devices or electrical and mechanical connection components. By simulating conditions such as frequency and amplitude of use, the performance changes of the testing device during long-term use are tested, including whether the insulation of the internal wiring is damaged, the degree of conductor fracture, and the voltage drop in the conductor. The following is a detailed description of the test:
Test purpose
Evaluate durability: Test the mechanical strength and electrical performance of the regulating device during long-term use.
Check insulation performance: Ensure that the insulation material of the internal wiring will not be damaged after long-term use.
Detecting conductor condition: evaluating whether the conductor is broken or whether the voltage drop is within the allowable range.
Verify safety: Ensure that the device will not cause safety issues due to mechanical or electrical failures during its lifecycle.
Test Standard
Common life testing standards for regulating devices include:
IEC 61058: Mechanical and electrical life testing applicable to electrical switches.
GB/T 15092: Chinese National Standard, equivalent to IEC 61058.
UL 61058: Underwriters Laboratories standard for life testing of electrical switches.
test equipment
Life testing machine:
Simulate the operating frequency and amplitude under normal usage conditions.
Electrical tester:
Measure the electrical performance of conductors, such as voltage drop and insulation resistance.
Mechanical testing device:
Evaluate the strength and durability of mechanical connections.
Environmental box (optional):
Simulate environmental conditions such as high temperature, low temperature, and humidity.
Test steps
Sample preparation:
Select a sample of the regulating device that meets the specifications to ensure it represents the actual usage conditions.
Set test parameters:
Set parameters such as operating frequency, amplitude, and number of cycles based on product specifications and usage scenarios.
For example, operate 10 times per minute and cycle test 10000 times.
Mechanical life test:
The service life testing machine simulates normal operation and records the wear, deformation, or fracture of mechanical components.
Electrical performance testing:
Measure the electrical performance of the conductor, such as voltage drop and insulation resistance, during or after the testing process.
Check if the insulation of the internal wiring is damaged.
Environmental testing (optional):
Test under high temperature, low temperature, or humidity conditions to evaluate the performance of the device in harsh environments.
Result evaluation:
Record the degree of wear of mechanical components, the fracture of conductors, changes in voltage drop, and changes in insulation performance.
Determine whether the device meets the lifespan requirements based on the test results.
Test points
Operating frequency and amplitude: Set according to actual usage conditions to ensure representative test results.
Electrical performance monitoring: Regularly measure voltage drop and insulation resistance to ensure that electrical performance is within the allowable range.
Environmental simulation: If the device is used in a special environment (such as high temperature, high humidity), corresponding environmental testing is required.
Data recording: Detailed recording of mechanical and electrical performance changes during the testing process.
result evaluation
Based on the test results, evaluating the lifespan and reliability of the regulating device typically includes the following indicators:
Mechanical properties:
Whether the mechanical components are worn, deformed, or broken.
Electrical performance:
Is the voltage drop of the conductor within the allowable range.
Does the insulation resistance meet the requirements.
safety
Whether there are safety hazards such as short circuit and leakage during the testing process of the device.
application
Household appliances: Test the lifespan of adjustment devices such as switches and knobs.
Industrial equipment: Evaluate the durability of components such as control panels and adjustment knobs.
Automotive industry: Testing the reliability of electrical and mechanical connection components inside vehicles.
By adjusting the device life test, the performance and safety of the device can be comprehensively evaluated in long-term use, providing a basis for product design and quality improvement.
