Automatic calibration line and method for intelligent type low-tension current transformers

Abstract

The invention discloses an automatic calibration line for intelligent type low-tension current transformers, comprising a warehouse in-out device, a loading and unloading device, an automatic identification device, a transmission device, an automatic line connecting and disconnecting device, a calibration device and a sorting and labeling device, wherein the warehouse in-out device realizes the automatic warehouse in-out of the intelligent type low-tension current transformers; the material loading and unloading device realizes the automatic loading and unloading of the intelligent type low-tension current transformers; the automatic identification device realizes the automatic identification of the intelligent type low-tension current transformers; the transmission device realizes the automatic transmission of the intelligent type low-tension current transformers; the automatic line connecting and disconnecting device realizes the automatic line connection of the intelligent type low-tension current transformers for the calibration by the calibration device and also realizes the automatic line disconnection of the intelligent type low-tension current transformers; and the sortingand labeling device realizes the automatic sorting of the intelligent type low-tension current transformers. The automatic calibration line is free from manually carrying out the warehouse in-out, the transmission, the identification, the sorting, the loading and unloading and the line connection and disconnection on the intelligent type low-tension current transformer when calibrating the intelligent type low-tension current transformer, and has the advantages of no personal error, high calibration efficiency, good automation degree and capability of automatically measuring multiple transformers. The invention also discloses an automatic calibration method of the intelligent type low-tension current transformer.

Description

technical field [0001] The invention relates to the field of electric power metering and testing, in particular to a system for verifying low-voltage current transformers for metering in electric power systems. Specifically, the invention relates to an intelligent low-voltage current transformer automatic verification line and an automatic verification method thereof. Background technique [0002] With the rapid development of my country's electric power industry, as one of the important components of electric energy metering devices, the use of metering transformers has also increased simultaneously, and these metering transformers must pass the verification of the transformer metering verification department before use. It can only be used, so that the transformer measurement and verification department, especially the provincial and municipal transformer measurement and verification department, also increases the transformer verification. At present, some provinces (such a...

AI Technical Summary

Problems solved by technology

[0005] 1) Manual actions will cause human errors, such as recognition errors, sorting errors, and wiring errors, which will seriously affect the verification process;

[0006] 2) Manual action limits the verification efficiency of the transformer verification device, and the daily verification quantity is usually 200;

[0007] 3) A series of manual actions do not form a systematic assembly line, and the degree of automation is poor

[0008] In addition, the transformer error verification device can only realize the error verification of the transformer, and the insulation resistance measurement, power frequency withstand voltage test, secondary winding turn-to-turn insulation strength test, and magnetic saturation margin measurement specified in the transformer verification regulations can only Manually test the transformers one by one, and there is no device for automatic measurement of multiple transformers at the same time
