Intelligent test line and method for distribution transformer

Abstract

The invention relates to an intelligent test line and method for a distribution transformer. The test line comprises a conveying line, wherein the conveying line is provided with a loading slow-transfer zone, a test zone, a discharging slow-transfer zone and a unloading zone; the test zone is provided with a pick-and-place platform and a pick-and-place mechanical arm; an automatic knob device anda wiring clamp are placed on the pick-and-place platform; a height sensor is disposed in the loading slow-transfer zone; and a CCD visual sensor is disposed on the pick-and-place mechanical arm. The method comprises the steps of S1, moving a transformer to be tested into the loading slow-transfer zone; S2:, sensing the height of the transformer and moving the transformer to be tested into the testzone; S3, adjusting the capture sensing height, obtaining the model type and the position and yaw angle information of the transformer; S4, connecting the wiring clamp and the automatic knob device with a binding post and a knob; S5, carrying out an automatic test; S6, putting the wiring clamp and the automatic knob device back to the pick-and-place platform; and S7, moving the conveying line forunloading subsequent products. The intelligent test line is safe, reliable, and accurate in testing, saves cost and has high degree of automation.

Description

technical field [0001] The invention mainly relates to the technical field of power grid transformer testing, in particular to an intelligent testing line and testing method for distribution transformers. Background technique [0002] Transformers have always been the main equipment in the construction of modern power networks, and play a key role in every link of power generation, power transmission and transformation, and power distribution. In recent years, thanks to a large amount of infrastructure investment and the rapid development of the power industry, the scale of the transformer industry has expanded rapidly and its production capacity has increased significantly, but there are also problems such as low industry concentration and outdated technology. The adjustment of energy structure and the construction of smart grid have brought new development opportunities for the transformer industry, and also raised higher technical challenges: the maturity and further prom...

AI Technical Summary

Problems solved by technology

1. For transformers, large current and voltage are huge safety challenges for operators. Improper operation and failure of test equipment and protective equipment may cause major accidents and cause unnecessary personnel and property losses.

2. The human operation error caused by manual wiring may affect the test results, thus affecting the judgment of whether the transformer is actually in normal use
