Performance detecting device for optical fiber type oil temperature sensor for transformer

Abstract

The invention provides a performance detecting device for an optical fiber type oil temperature sensor for a transformer. The detecting device comprises a transformer oil tank simulating device. The transformer oil tank simulating device comprises an oil tank filled with insulating oil, and a mercurial thermometer and the optical fiber type oil temperature sensor are installed on the oil tank. The mercurial thermometer and the optical fiber type oil temperature sensor are used for measuring the temperature of the insulating oil. The optical fiber type oil temperature sensor is connected with a temperature collecting system. By means of the detecting device in the technical scheme, the installation sealing performance, the temperature measurement accuracy, the fault alarming performance and the seismic resistance of the optical fiber type oil temperature sensor for the transformer can be detected, the defects that in the prior art, when an optical fiber type oil temperature measuring system is connected into a grid, detection calibration is not carried out, and performance and reliability can not be detected are overcome, and technical supports are provided for guaranteeing safe and reliable running of the transformer.

Description

technical field [0001] The invention relates to a detection device, in particular to a performance detection device of an optical fiber oil temperature sensor for a transformer, which belongs to the field of intelligent electric appliances. Background technique [0002] With the rapid increase of electricity consumption, the problem of unbalanced electricity consumption is particularly prominent, and many places are facing the problem of electricity shortage. In places where electricity is scarce, it is necessary to carry out grid interconnection and develop UHV strong and smart grids. The power grid has become the foundation and an important part of the development of an industrialized and informationized society; at the same time, the power grid is also constantly absorbing the achievements of industrialization and informatization, so that various advanced technologies can be integrated and applied in the primary equipment of power transmission and transformation, which gr...

Problems solved by technology

The optical fiber oil temperature sensor directly contacts the insulating oil and winding temperature, and its measurement data is more accurate and reliable. When it is transmitted in the substation, it is transmitted by optical fiber, and there is no signal interference. Some applications have been carried out in recent years, but the optical fiber oil temperature sensor The measurement system lacks detection and verification when it is connected to the network, and its performance and reliability verification is insufficient. If it is directly verified after on-site installation, it is difficult to replace and maintain if there is a problem
