Abstract

Using totally enclosed type vortex compressor to drive environmental protective working medium, the method makes working medium circulate in independent close working loop. Based on different heat load on transformer, heat balance type expansion valve carries out automatic adjustment for flow rate of working medium dynamically, and intellective adjustment for refrigerating capacity output from heat sink so as to make transformer work at working temperature setup stably. Advantages are: high heat exchanger effectiveness; transformer oil works at stable state so as to raise work efficiency of transformer greatly, and raise service life of transformer oil and transformer as well as save energy sources.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a water-air double-condensation transformer oil circulation cooling method and a circulation cooling device. Background technique [0002] In public power grids and enterprise power grids, all electrical equipment connected to single-phase and three-phase AC power grids and working according to the principle of electromagnetic induction requires magnetizing current when establishing a magnetic field. A transformer is a typical device that not only absorbs active power from the power system, but also absorbs magnetizing energy to generate the alternating magnetic fields necessary for these normal operations. The magnetizing current does not participate in the energy conversion. The magnetizing current flows in a large amount in the system, which will increase the line loss and reduce the power quality, which will have adverse effects on the power generation, power supply, and...
