Problems solved by technology

[0003] In order to ensure the normal use of oil-immersed transformers, the oil-immersed transformers are generally limited to work under rated loads. However, the transformers will suffer from aging and insulation capacity degradation during long-term use, resulting in a decrease in their load capacity. If the rated load on the transformer nameplate is used, there will be safety risks, so it is necessary to evaluate whether the load of the transformer is consistent with the factory standard

Abstract

The invention provides a transformer comprehensive load capacity evaluation system, an oil temperature detection mechanism, an evaluation module, an indicator light and several load modules. The oil temperature detection mechanism includes a first straight rod, a second straight rod, an adjustment rod, and a thermal bimetallic sheet And the push rod, after obtaining the rated load on the transformer nameplate and the upper limit of the insulating oil temperature, move the adjustment lever, and select the corresponding load module at the same time, the main control unit controls the load modules to connect to the transformer in turn, and after the transformer is running with load, The temperature of the internal insulating oil will rise, causing the heated bimetal to bend upwards, thereby driving the push rod to move upward. If all the load modules are connected to the transformer, the push rod can just move to the bottom of the adjustment rod and press the button Contact, the main control unit judges that the load status of the transformer is normal. If the button is triggered when the load modules are not fully connected, it means that the load status of the transformer does not match the calibration, and maintenance is required to prevent accidents.

Description

technical field [0001] The invention relates to the technical field of power equipment evaluation, in particular to a transformer comprehensive load capacity evaluation system. Background technique [0002] For modern society, safe, reliable and convenient electricity has become an essential component of social production and people's life. As an important power conversion equipment and connection device in the power system, large-scale power transformers are related to the safe and reliable operation of the system. The safety and reliability of power grid operation, the continuous and reliable supply and transmission of power are important factors for maintaining social stability, improving the quality of life of the people, and accelerating the production and development of the whole society. [0003] In order to ensure the normal use of oil-immersed transformers, the oil-immersed transformers are generally limited to work under rated loads. However, the transformers will ...
