Abstract

The invention belongs to the technical field of power transformers, and particularly relates to an intelligent power transformer dielectric loss factor and insulation resistance measuring device. In order to solve the problem that a worker is easily injured due to electric leakage in the measurement process of a power transformer because of humid air, when an existing power transformer is used formeasuring the dielectric loss factor and insulation resistance, the following scheme is proposed: the device comprises a bottom plate, fixed plates are fixedly connected to the two ends of the outerwall of the top of the bottom plate, and supporting plates are fixedly connected to the outer walls of the opposite sides of the two fixed plates. According to the invention, a heating plate, an electric heating wire, an air pump, an air pipe and a sealing cover are arranged, when the dielectric loss factor and the insulation resistance of the power transformer are measured, external air is guidedinto an air pipe through the air pump, the air is heated through the heating plate, the air sprayed out of air holes is hot air, the detected environment is dehumidified, and the safety in the detection process is ensured.

Description

technical field [0001] The invention relates to the technical field of power transformers, in particular to an intelligent power transformer dielectric loss factor and insulation resistance measuring device. Background technique [0002] A power transformer is a static electrical device that is used to change an AC voltage (current) of a certain value into another voltage (current) with the same frequency or several different values; a transformer is used to transform AC A static electrical device that transmits alternating current energy through voltage and current. It is based on the principle of electromagnetic induction to achieve electrical energy transfer. Transformers can be divided into power transformers, test transformers, instrument transformers and special-purpose transformers in terms of their uses: power transformers are necessary equipment for power transmission and distribution, and power distribution for power users; test transformers can withstand voltage ...
