随着断路器产品技术和水平的日益提高,对于产品的EMC指标要求和测试环境要求更加严酷。在进行EMC抗辐射干扰旋转测试时,应力求达到有限空间内屏蔽性能好、连接接线方便以及外形美观等一系列要求。若将用于向被测产品输出大电流的测试电源放置于暗室内,则对测试结果造成一定影响。为满足要求,自主设计研发了一套大电流升降装置。利用这套装置可让被测产品与测试电源达到很好的隔离效果,减少了测试环境对测试结果的影响。
With the increasing technology and level of circuit breaker products, EMC requirements and test environment requirements for products are more stringent. In the EMC anti-radiation interference rotation test, we should strive to achieve shielding properties within a limited space, connecting the convenience of wiring and appearance and a series of requirements. If the test product used to output a large current to the product under test is placed in a dark room, the test result will be affected to some extent. In order to meet the requirements, independent design and development of a large current lifting device. This device can be used to test the product under test and the power supply to achieve a good isolation effect, reducing the impact of the test environment on the test results.
