The low-frequency transformer automatic comprehensive test machine can be applied to the field of transformer testing devices.

Description

technical field [0001] The invention relates to a testing machine, in particular to a low-frequency transformer automatic comprehensive testing machine based on a PLC-controlled GROOVY data acquisition and analysis system. Background technique [0002] The routine items of power measurement for low-frequency transformers include no-load current, no-load loss, no-load voltage, load voltage, load current, power factor, insulation resistance, etc. In the testing of the above items, each transformer manufacturer currently uses customized The tooling connects the windings and related parts with the measuring instruments. Due to the wide variety of transformers, the windings, lead-out methods and package sizes are different from the technical requirements of the transformer itself, so that each item of each transformer requires a special tooling fixture to be used normally. In this way, not only the consumption of tooling is huge, but also in some special projects, fixtures need t...

[0002] The routine items of power measurement for low-frequency transformers include no-load current, no-load loss, no-load voltage, load voltage, load current, power factor, insulation resistance, etc. In the testing of the above items, each transformer manufacturer currently uses customized The tooling connects the windings and related parts with the measuring instruments. Due to the wide variety of transformers, the windings, lead-out methods and package sizes are different from the technical requirements of the transformer itself, so that each item of each transformer requires a special tooling fixture to be used normally. In this way, not only the consumption of tooling is huge, but also in some special projects, fixtures need to be replaced frequently according to technical requirements, which greatly reduces test efficiency and indirectly increases labor costs

[0003] Furthermore, the entire process of tooling and testing lines is now manually operated, with prominent human factors, and there is a risk of missed and wrong judgments, and now customers have strict requirements on the quality of transformers. How to effectively avoid the outflow of defective products is a problem that various transformer manufacturers continue to solve!
