Abstract
Description
Technical Field
[0001] The utility model relates to the field of relay testing, and particularly to an integrated testing device for train socket relays. Background Technique
[0002] Relays are the most widely used electrical components in train control systems. The occurrence of their failures affects the safe and punctual operation of trains. Therefore, the demand for relay testing is a routine task. The original relay testing methods mainly rely on manual operation and independent testing equipment. Such testing methods have various defects, which not only affect the testing efficiency but also may have an adverse impact on the accuracy of testing results.
[0003] First of all, in the original testing method, each relay needs to be independently installed and wired, which is a very cumbersome and time-consuming process. For large-scale relay testing, this one-by-one processing method greatly increases the testing cycle and reduces the work efficiency. At the same time, multiple independent wiring points also increase the probability of errors. Any wiring error may lead to test failure or inaccurate test results.
[0004] Secondly, the original testing method has a large error in testing the contact resistance value. Due to various factors such as manual operation, wiring quality, and testing environment during the testing process, the test data has large fluctuations and uncertainties. This not only affects the accuracy of the relay performance evaluation but also may bring potential risks to subsequent product quality and use safety.
[0005] In addition, there is no dedicated pin base for the relay quick plug-in and installation tooling currently. This means that after each test, a large amount of time and effort are required for the disassembly and reinstallation of the relay, which undoubtedly increases the complexity and time-consuming nature of the testing work. At the same time, due to the lack of standardized installation tooling, the operation difficulty and the possibility of errors are also increased.
[0006] To sum up, the original relay testing method has defects such as low work efficiency, high wiring error rate, poor testing accuracy, and complex operation. These problems limit the development and application scope of relay testing technology and also increase the testing cost and risk. Therefore, developing a new type of integrated testing device to overcome these defects has important practical significance and application value. Content of the Utility Model
