Abstract

The invention relates to a method and a system for testing the high temperature tolerance and the compatibility of an optical fiber in transformer oil. On a basis of integrating and improving traditional optical-fiber high-temperature-resistant tests and oil compatibility tests, the invention provides a method and a system for testing the high temperature tolerance and the compatibility of the optical fiber in the oil. The method comprises the following steps of: keeping the state of a constant temperature of 105 DEG C and stabilizing for 164 h; and analyzing the high temperature tolerance and the compatibility of the optical fiber in the transformer oil by comparing the changes of the optical fiber sensing and the optical guide characteristic as well as the changes of the transformer oil chromatography and the oil characteristic. Compared with the prior art, the invention has the advantages of controllable test temperature, little external environment influence and simple and convenient operation.

Description

technical field [0001] The invention relates to a method and system for testing the high temperature resistance and compatibility of optical fibers in transformer oil, and belongs to the technical field of transformer operation measurement and protection in the electric power industry. Background technique [0002] Optical fiber sensing technology is more and more widely used in transformers. Optical fiber sensing requires optical fibers to be placed inside the transformer and immersed in transformer oil under high temperature conditions inside the transformer for a long time. When the optical fiber in the transformer oil is running, it will gradually deteriorate due to factors such as high temperature and oil erosion, which will affect the optical fiber sensing and light guiding characteristics; or the chemical reaction between the optical fiber and the transformer oil will deteriorate the insulation performance of the transformer oil. Therefore, special methods and devices...
