Problems solved by technology

[0004] Since the transformers are operated at high voltage, it is inconvenient to directly detect the cooling effect of the cooling equipment when designing the cooling equipment. It can only be calculated theoretically through simulation software, which will easily lead to certain problems when designing the cooling equipment. defect problem

Abstract

The embodiment of the present invention discloses a cooling verification method for power transformer cooling equipment, which includes establishing a temperature database of each part of the transformer when there is no cooling equipment, and then manufacturing a scaled-down heat sink model, and connecting it to the oil cooling cycle , preheating through the heating device, and using the temperature fine-tuning device to fine-tune the temperature of the oil cooling liquid according to the temperature database, and then install the cooling equipment that has been scaled down in proportion, start the cooling equipment to detect the temperature change of the heat sink, and store the collected temperature The change data is compared with the cooling simulation data, and the cooling verification is completed. The cooling equipment includes the heat dissipation pipe, the oil outlet pipe, the heating box for heating the oil cooling liquid, and the cooling device for circulating the oil cooling liquid. The booster pump and the oil inlet pipe use fine-tuning components to control the temperature difference between multiple heat sinks in actual use, so that the simulation can be more realistic.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a cooling verification method and verification device for power transformer cooling equipment. Background technique [0002] A transformer is a static electrical device that converts AC power of one voltage into AC power of another voltage with the same frequency through the application of electromagnetic induction. The main components are primary coil, secondary coil and iron core. [0003] There are many kinds of current transformers, which can be divided into dry-type transformers and oil-immersed transformers according to the cooling method. For oil-immersed transformers, oil can be used as the cooling medium to achieve rapid cooling of the transformer during operation, but In the actual practical process, depending on the external environment, sometimes it is necessary to install a radiator on the oil-cooled heat sink to stabilize the temperature of the transformer with...
