Description

Module switchable dial device and test method for flexible testing of IED equipment

Technical field

The invention relates to the field of flexibility testing of IED equipment, in particular to a module switchable dial plate device and a testing method for the flexibility testing of IED equipment.

Background technique

The testing of existing power system intelligent equipment IED equipment is manual fixture plus semi-automated testing. Requires human intervention in the testing process. The vast majority of manufacturers now only carry out their own automatic production and testing of two products. Non-standardized products and small batches of multiple varieties are important reasons to confuse them all to start automatic production and testing. The closed loop test of the original technical foundation corresponds to different test equipment: during the specific implementation process, it was found that the products of different manufacturers, the same product and different series of the same product of the same company are very different. There is no uniform standard for products. It brings a lot of inconvenience to automatic testing, and needs to customize the test system and fixture separately, which is also the mainstream method in the industry. There are several problems with this mechanical design. The fixture is customized for a class of products and does not have reusability. The semi-automated test may cause personnel errors and make the test incomplete. In order to increase the integrity of the test and test coverage, we 2016 Adopting the switch mode of the dial, it has applied for a patent in 2016: a kind of interchangeable dial-type universal testing equipment. And in the application design of the universal test equipment with switchable dial, we found that the dial switch also has a certain scope of application. The structure of some IED devices does not have a fixed pattern of plate composition. The plates can be arbitrarily configured. The combination and arrangement of plug-ins may constitute 300 to 3,000 varieties of devices. Faced with such equipment, we need to make too many dials.
