Fixing device of optical fiber temperature sensor

Abstract

The invention relates to a fixing device of an optical fiber temperature sensor. The fixing device of the optical fiber temperature sensor comprises an insulating sheet, the optical fiber temperature sensor and pigtail. A groove is arranged in the insulating sheet. A connector of the pigtail is connected with a connecting end of the optical fiber temperature sensor. The optical fiber temperature sensor is fixedly arranged in the groove. A packaging boy made of a polytetrafluoroethylene material is wrapped on the surface of the pigtail. A protruding outer edge is arranged at the edge of the insulating sheet. The tail fiber is fixed with the insulating sheet provided with the protruding outer edge through the groove. A groove matched with the protruding outer edge is arranged in the surface of the packaging body. The fixing device of the optical fiber temperature sensor provided by the invention has the effect of protecting, installing and fixing the optical fiber temperature sensor. The fixing device of the optical fiber temperature sensor is very convenient to install, and can be fixed and protected by the special insulating sheet in the device in the common storage and conveying process of the optical fiber temperature sensor.

Description

technical field [0001] The invention relates to a sensor fixing device inside a transformer winding gap, in particular to a fiber optic temperature sensor fixing device. Background technique [0002] The power transformer is the most important electrical equipment in the power system, and the thermal effect is the decisive factor for the load capacity of the transformer. It is very important and necessary to monitor and study the thermal effect of transformers. [0003] For oil-immersed transformers, the winding temperature directly determines the operation safety and aging rate of the transformer, and the monitoring of winding temperature has always been an important and difficult point. The potential of the transformer winding is high, and the internal insulation requirements of the transformer are high. The traditional methods include indirect measurement and direct measurement. The real-time and accuracy of indirect measurement methods are not good. Traditional direct...

Problems solved by technology

However, the optical fiber itself is relatively fragile, and it cannot be protected by armor when used inside the transformer. The optical fiber sensor is small in size, which makes it inconvenient to use and install the optical fiber for temperature measurement and is easy to cause damage to the optical fiber.
