Abstract

The invention discloses a transformer service life estimation system. The transformer service life estimation system comprises a transformer monitoring data acquisition module which is used for acquiring transformer monitoring data, a thermal aging accelerating aging calculation module which is connected with the transformer monitoring data acquisition module and used for calculating a thermal aging accelerating aging factor, an electrothermal aging accelerating aging calculation module which is connected with the transformer monitoring data acquisition module and used for calculating an electrothermal aging accelerating aging factor, and a transformer service life calculation module which is connected with the thermal aging accelerating aging calculation module and the electrothermal aging accelerating aging calculation module and used for calculating the service life of a transformer. The expected service life of the transformer is calculated according to the data recorded by a transformer online monitoring device so that the basis is provided for maintenance personnel in making a maintenance plan, and thus the system has great application prospect and popularization value.

Description

technical field [0001] The invention belongs to the technical field of transformer condition maintenance, and in particular relates to a transformer service life estimation system. Background technique [0002] The power transformer is an important electrical equipment in the power system. In the links of power generation, transmission and distribution, it plays a key role in increasing the voltage to facilitate long-distance transmission of electric energy and reducing the voltage to meet the power supply. The large-capacity power transformer itself is also very expensive equipment. In the power system, not only a large number of transformers are required, but also good performance and reliable operation of the transformers are required. However, the utilization rate of each transformer in operation is not the same, and some transformers have higher utilization rate, while others have lower utilization rate. As a result, the insulation aging speed of the transformer is in...
