Electrical life durability test system for relay switching devices

n With nearly 20 years of market accumulation of wenshun, we have cooperated with more than 500 + manufacturers and scientific research institutions. Through in-depth analysis and exploration of the switch relay and other controller parts industry, the application scenarios of a series of test products launched by wenshun company have covered the preliminary research and development of welding machine products, production inspection and finished product aging test, Provide switching device manufacturers with diversified test solutions for the whole process of products.

n Switching devices, AC relays, high-voltage DC contactors, AC and DC fuses are widely used in power equipment. Their reliability and related electrical performance parameters are important basis for engineers' product selection and application scheme. The performance test of relay switching products is an important test to measure and evaluate the reliability and performance of products. It is also helpful to analyze the causes of contactor failure and improve product quality.

Wenshun switching device automatic test system

Realize the monitoring of the switching state and the switching state of the electrical life system, the monitoring of the state of each test object, the input and recording of test parameters, the recording and editing of the test process (test times and progress, etc.), the intelligent control of the test process (effectively allocate the time of each test according to the load), and the monitoring of the test safety status, Alarm and record of abnormal test conditions, query of historical test records, etc. The test system is operated by touch screen or industrial computer. Users can and edit test data, and fool type full-automatic control in the test process. The system has two methods: automatic test and manual test, which only need to set simple test parameters. Equipped with USB port, it is easy to plug in USB flash disk, printer and other devices. During operation, you only need to set the test parameters, without manual monitoring, manual recording, curve drawing and other cumbersome labor, so as to reduce the labor intensity and improve the work efficiency. You can also read the data to the computer after the work.
