An optical fiber pre-embedded module, system and overall system for transformer temperature monitoring

Abstract

The embodiment of the invention discloses an optical fiber pre-embedded module for transformer temperature monitoring, an optical fiber pre-embedded system for transformer temperature monitoring and a general system for transformer temperature monitoring. Simultaneously monitor the temperature monitoring of multiple positions, and then can accurately find out the hot spot position of the transformer and measure the temperature of the hot spot position, which solves the problem that the existing technology is difficult to realize multi-point monitoring, cannot correctly reflect the temperature distribution in the transformer, and cannot be accurate Find out the technical problem that the measured hot spot temperature of the transformer winding is inaccurate due to the hot spot position of the transformer.

Description

technical field [0001] The invention relates to the technical field of transformer testing, in particular to an optical fiber pre-embedded module, system and overall system for transformer temperature monitoring. Background technique [0002] With the development of my country's urban and rural economies, rural electricity consumption has grown rapidly, and distribution transformers often experience a sharp increase in load during high temperatures in summer and around the Spring Festival in winter, resulting in severe overloading of distribution transformers in some areas. The high ignition point, flash point, and environmental friendliness of vegetable oil, as well as delaying the aging of paper and prolonging the insulation life of transformers, make the development of high-overload-resistant vegetable oil distribution transformers the best solution to this problem. When the transformer is running, the hot spot temperature of the winding is of great significance to the sa...
