Oil-immersed Transformer Fiber Optic Temperature Measuring Probe Fixing Device

Abstract

The invention relates to the field of optical fiber temperature measuring equipment for oil-immersed transformers, and discloses a fixing device for an optical fiber temperature measuring probe of an oil-immersed transformer, which includes insulating pads arranged between transformer coils. The strip-shaped card slot hole adapted to the temperature probe assembly, the strip-shaped card slot hole is provided with a limiting round hole larger than the diameter of the card slot hole; the transmission optical fiber and the optical fiber temperature-sensing probe are sequentially clamped in the strip-shaped card slot In the hole, the part of the transmission optical fiber corresponding to the limiting round hole is provided with a limiting convex part adapted to the limiting circular hole, and the limiting convex part cooperates with the limiting circular hole to limit the optical fiber Axial movement of the temperature probe assembly. The optical fiber temperature measuring probe assembly of the present invention is firmly fixed with the insulating cardboard, avoiding the problem of axial shedding of the optical fiber probe, and ensuring that the optical fiber probe can perform long-term safety detection inside the oil-immersed transformer.

Description

technical field [0001] The invention relates to the field of optical fiber temperature measuring equipment for oil-immersed transformers, in particular to a fixing device for an optical fiber temperature measuring probe of an oil-immersed transformer. Background technique [0002] Power transformer is one of the core equipment of modern power system. The internal temperature of the transformer, especially the hot spot temperature of the winding, is directly related to the insulation performance and aging life of the transformer; Safe operation causes danger, and the temperature is too low, and the load capacity of the transformer cannot be fully utilized, thereby reducing the economic effect of the transformer. Therefore, it is of great significance to monitor the temperature of transformer windings to ensure the safety and reliability of transformers, economical operation and prolong service life. [0003] With the development of optical fiber technology and the vigorous p...
