Embodiment Construction

[0043] A thermal performance test system for a sheet radiator for a transformer

[0044] A thermal performance test system for a transformer fin radiator proposed in this embodiment includes a main oil tank 5, an oil circulation pipeline, a prototype connection unit, a heating unit and a control unit.

[0045] Both ends of the oil circulation pipeline are respectively connected to a circulation outlet 51 located at the lower end of the main oil tank 5 and a circulation inlet 52 located at the upper end of the main oil tank 5 . A circulation pump 3 is arranged on the oil circulation pipeline. When the circulation pump 3 is working and the oil circulation pipeline is conducting, the oil in the main oil tank 5 circulates through the oil circulation pipeline.

[0046] The heating part includes a plurality of heating units for heating the main oil tank 5 , and the plurality of heating units are distributed along the height direction of the main oil tank 5 . like figure 1 As show...

Abstract

A thermal performance test system for a finned radiator for a transformer comprises a main oil tank, an oil circulation pipeline, a prototype access part, a heating part and a control part. two ends of the oil circulation pipeline are respectively connected with a circulation outlet at the lower end of the main oil tank and a circulation inlet at the upper end of the main oil tank; a circulating pump is arranged on the oil circulating pipeline; when the circulating pump works and the oil circulating pipeline is in a conducting state, oil in the main oil tank circularly flows through the oil circulating pipeline; the heating part comprises a plurality of heating units used for heating the main oil tank, and the heating units are distributed in the height direction of the main oil tank; and the prototype access part is used for communicating the radiator prototype with the main oil tank, so that the main oil tank and the radiator prototype form a heat dissipation test loop. The invention provides a universal test system suitable for performance tests of various radiator prototypes.

Description

technical field [0001] The invention relates to the field of radiator testing, in particular to a thermal performance testing system and method for a sheet radiator for a transformer. Background technique [0002] Transformer is one of the important electrical equipment in power system. When the transformer is running, due to the existence of resistance and reluctance, the iron core, winding and steel structure will all produce heat loss, causing the temperature of the transformer to rise. Excessive temperature of the transformer not only increases the transmission loss, but also causes accelerated aging of the transformer insulation material, reduces the utilization rate of the transformer, and shortens the service life of the transformer. With the increase of transformer capacity, the problem of transformer overheating becomes more and more prominent. [0003] As the mainstream radiator of large oil-immersed transformers, chip radiator has the advantages of low cost, sim...
