Embodiment Construction

[0021] In order to better understand the technical content of the present invention, a specific embodiment is provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0022] see Figure 1 to Figure 3 , a transformer comprehensive load capacity evaluation system provided by the present invention includes an oil temperature detection mechanism, an evaluation module, an indicator light 1 and several load modules 2, and the oil temperature detection mechanism includes a first straight rod 3, a second straight rod 4. Adjusting rod 5, thermal bimetal 6 and push rod 7, said adjusting rod 5 is slidably arranged between the first straight rod 3 and the second straight rod 4, the two ends of said thermal bimetal 6 are connected with the first The straight bar 3 and the second straight bar 4 are connected to the side walls, and are positioned below the adjusting rod 5. The push rod 7 is arranged on the upper surface of the thermal bi...

Abstract

The invention provides a transformer comprehensive load capacity evaluation system, which comprises an oil temperature detection mechanism, an evaluation module, an indicating lamp and a plurality ofload modules. The oil temperature detection mechanism comprises a first straight rod, a second straight rod, an adjusting rod, a thermal bimetallic strip and a push rod. After the rated load of the transformer nameplate and the upper limit value of the insulating oil temperature are obtained, the adjusting rod is moved, meanwhile, the corresponding load modules are selected, the main control unitsequentially controls the load modules to be connected into the transformer, after the transformer operates with load, the temperature of the insulating oil in the transformer can rise, the thermal bimetallic strip is heated to be bent upwards, and therefore the push rod is driven to move upwards, and if all the load modules are connected into the transformer, the push rod can just move to the bottom of the adjusting rod and make contact with the pressing button, the main control unit judges that the load state of the transformer is normal, and if the pressing button is triggered when the loadmodule is not completely connected, it shows that the load state of the transformer does not conform to calibration, maintenance is needed, and accidents are prevented from happening.

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 ...
