Problems solved by technology
[0002] When testing capacitors on-site, you usually have to face multi-layer capacitor racks, which are huge in number, and they are tested one by one. The wiring of the test process is complicated, and testers need to frequently move the instrument. Higher capacitor racks require staff to climb to complete. Testing, on-site workload is heavy, testing efficiency is low and there are certain safety hazards

The invention discloses an anomaly screening test device for automatically switching parallel capacitors based on the Internet of Things. The anomaly screening test device comprises an industrial personal computer, a display, at least one local control capacitance measurement unit, at least one remote capacitance measurement unit, a capacitance acquisition unit, an execution unit and an alarm unit. According to the invention, capacitance data of a capacitor is read through a capacitance acquisition unit, a local control capacitance test unit or a remote capacitance measurement unit receives the capacitance data and carries out a capacitance data abnormity comparison test, test judgment data is transmitted to an industrial personal computer, and the industrial personal computer sends an instruction to an execution unit according to the judgment data. The execution unit controls the automatic switching of the multi-channel bus Internet of Things switch or the multi-channel wireless Internet of Things switch, the programmed control automatic switching is realized, the local or remote capacitance test unit can complete the rapid test of a plurality of capacitors only through one capacitance test module, and the abnormal test efficiency of the capacitance is improved.
Description
technical field [0001] The invention relates to the technical field of capacitor testing, in particular to an abnormal screening test device for automatically switching parallel capacitors based on the Internet of Things. Background technique [0002] When testing capacitors on-site, you usually have to face multi-layer capacitor racks, which are huge in number, and they are tested one by one. The wiring of the test process is complicated, and testers need to frequently move the instrument. Higher capacitor racks require staff to climb to complete. For testing, the on-site workload is heavy, the testing efficiency is low, and there are certain safety hazards. Contents of the invention [0003] The object of the present invention is: in order to solve the above-mentioned problems, the abnormal screening test device based on the Internet of Things for automatically switching parallel capacitors is proposed. [0004] In order to achieve the above object, the present inventio...
