An intelligent control method for strong oil air cooling of transformer

Abstract

The invention discloses an intelligent control method for strong oil air cooling of a transformer, which comprises the following steps: step a: the program starts, initializes, and then turns into a main program for circulating operation; B, sample and processing that upper oil temperature of the transform; C, judge that sampling temperature in the step b; Step d: if the oil temperature judged instep c is greater than the upper limit temperature, the fan automatically switches on and off subroutine 1; If the oil temperature judged in the step c is less than the upper limit temperature, the fan automatically switches on and off the subroutine 2; E, sending that temperature signal and the running program to a liquid crystal screen for display; (f) send that upper oil temperature of the current transformer and the operation condition of the fan to the upper compute through a remote communication program; Step g: End the current program and return to step b. The invention has the advantages that the problems that the prior art is not conducive to energy saving and effective utilization of equipment, and the air cooling device is frequently switched on and off are solved.

Description

technical field [0001] The invention relates to the technical field of transformer temperature control, in particular to an intelligent control method for strong oil air cooling of transformers. Background technique [0002] The number of strong oil circulation transformers in the power grid is increasing day by day, and they play an important role in the operation of the power grid. At present, the transformers in domestic 220kV and above substations generally adopt the cooling method of strong oil air cooling. Since the cooling efficiency is higher than that of the natural circulation oil-immersed air-cooled transformer, the transformer is small in size, saves materials and is economical, and it also provides convenience for the development of super-large-capacity transformers. [0003] At present, the configuration of air-cooling devices for large-scale power transformers in my country is: according to the size of the capacity, it is equipped with groups of air-cooling de...
