Oil-immersed transformer and transformer temperature control system

Abstract

The invention provides an oil-immersed transformer and a transformer temperature control system, and the oil-immersed transformer comprises: a transformer body, the bottom of which is provided with a base assembly; a heat dissipation assembly is provided with a booster pump and a heat dissipation fan; by arranging an oil outlet pipe, the booster pump and an S-shaped heat dissipation pipe, oil in the oil-immersed transformer body can flow conveniently, in the oil flowing process, heat on the surface of the S-shaped heat dissipation pipe can be dissipated conveniently by arranging an air inlet pipe, the heat dissipation fan, a heat dissipation net and an air outlet, therefore the whole transformer has a rapid heat dissipation effect. According to the invention, the operation rule between the operation data value and the operation average value of the oil-immersed transformer can be configured by monitoring personnel according to the actual operation state on the basis of the requirement of a monitoring system. Calculation of each oil-immersed transformer can be processed in a unified mode in the system, it is guaranteed that conclusions have mutual reference values, and unified monitoring can be achieved.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an oil-immersed transformer and a transformer temperature control system. Background technique [0002] The distribution transformer is one of the important equipment in the power supply and distribution system of industrial and mining enterprises and civil buildings. It reduces the 10kV or 35kV network voltage to the 230 / 400V bus voltage used by users. These products are suitable for AC 50 (60) Hz, three-phase maximum rated capacity of 2500kVA, and can be used indoors or outdoors. [0003] Most of the existing distribution transformers use oil-immersed transformers. During the use of oil-immersed transformers, since the oil is sealed in a dedicated oil tank, the fluidity of the oil is poor, which is not conducive to the heat dissipation of oil-immersed transformers. [0004] Moreover, because the current monitoring form and heat dissipation method of oil-immersed transform...

Problems solved by technology

[0003]Most of the existing distribution transformers use oil-immersed transformers. During the use of oil-immersed transformers, the oil is sealed in a special oil tank, resulting in The fluidity of oil is poor, which is not conducive to the heat dissipation of oil-immersed transformers

[0004]Because the current monitoring form and heat dissipation method of oil-immersed transformers only monitor the transformer itself, that is, monitor the temperature state of the transformer body, if If the temperature is too high, the cooling process will be carried out. This monitoring method lacks the linkage monitoring of multiple distribution transformers in the distribution network. The temperature of the transformer body exceeds the threshold, which may have affected the entire power distribution network. At this time, measures such as cooling down may affect the normal power supply process.
