Description

Technical Field

[0001] The invention belongs to the technical field of automatic detection of insulating oil of a state-grid transformer, and in particular relates to a mobile laboratory system for automatic detection of insulating oil of a state-grid transformer. Background Art

[0002] Under the background of the current transformation and development of the new power system, domestic transformer insulating oil quality analysis experiments are facing new challenges and opportunities.

[0003] 1) Many areas in China are sparsely populated and the units are scattered, which is only suitable for mobile oil and water detection tests. The country is vast and the distribution of various power units and substations is relatively scattered, which makes the traditional centralized laboratory testing method inconvenient in terms of time and space.

[0004] 2) The temperature difference between day and night is large in China, and oil is not easy to preserve, so it is only suitable for mobile oil-water detection tests. The temperature difference between day and night is large in many areas of China. This climatic condition puts higher requirements on the preservation and transportation of transformer insulating oil. Traditional oil storage and transportation methods may cause changes in oil performance due to temperature changes, affecting the accuracy of the test results.

[0005] 3) The number of samples in a single experiment is small, and it is not suitable to be centralized in a laboratory for unified testing. Due to the scattered distribution of domestic power units, the number of samples collected from each point at a time may be relatively small. If these samples are centralized in a laboratory for unified testing, it will not only increase transportation costs and time, but also make it difficult to compare and analyze batches due to insufficient sample quantity. Summary of the invention

[0006] The purpose of the present invention is to provide a mobile laboratory system for automatic detection of transformer insulating oil of the State Grid, which can be freely moved so that the automatic detection experiment of transformer insulating oil is free from the restrictions of region, temperature and environment.

[0014] The first experimental instrument and the second experimental instrument can customize the testing content according to customer needs.
