Embodiment 1
[0048] Please refer to figure 1 , the life assessment methods of power transformers include:
[0049] Step S101, determining the economic life of the transformer according to the constructed transformer life cycle cost function.
[0050] In the embodiment of the present invention, the economic life of the transformer is reflected from the economic index of the transformer. In the early stage of transformer operation, the economic index decreases year by year. start to fall. The economic life of the transformer is considered to be reached when the economic index of the transformer appears an inflection point.
[0051]Optionally, step S101 is implemented by adding the initial investment cost of the transformer, the maintenance cost of the transformer, the power failure loss cost of the transformer, and the disposal cost of the transformer to construct a total cost of the transformer. life cycle cost function;
[0052] The operating time of the transformer when the value of t...
Embodiment 2
[0106] Such as image 3 As shown, a life evaluation device for a power transformer includes:
[0107] The first determination module 301 is configured to determine the economic life of the transformer according to the constructed transformer life cycle cost function;
[0108] A first obtaining module 302, configured to obtain the economic life cycle cost of the transformer according to the economic life;
[0109] The second determination module 303 is configured to determine the current operating life of the transformer according to the commissioning time of the transformer;
[0110] The second obtaining module 304 is configured to obtain the current operating life cycle cost of the transformer according to the current operating life;
[0111] The third determining module 305 is configured to determine the physical life of the transformer according to the health level index of the transformer and the current operating life;
[0112] A third obtaining module 306, configured ...
