Automatic switching device for intelligently controlling multiple transformers

Abstract

Disclosed is an automatic switching device for intelligently controlling multiple transformers. The automatic switching device is applicable to power supply networks of large and medium factories, capacity of a controlled system is preset to be 10MW, and primary side voltage of the transformers is 10kV. A chip 80C51, developed and produced by Intel Company, in a single chip microcomputer in a MSC-51 series is selected for a control unit of the automatic switching device, and novel setting of hardware, a clock program and a keyboard program is adopted.

Description

technical field [0001] The invention relates to an intelligent control device, in particular to an intelligent control device for automatic switching of multiple transformers. Background technique [0002] Since the power consumption of various departments of the enterprise is random, and the load is uneven day and night, and the operation mode of the transformer is different in different seasons, the transformer is often in a light-load or no-load operation state. As a result, the power factor of the transformer decreases and the current increases. When the current flows through the transformer and the line, a large power loss will occur, which not only increases the total active power loss of the factory power system, but also accelerates the insulation aging of the transformer. This intelligent control device for automatic switching of multiple transformers can reasonably control the number of transformers according to the change of factory load, so that the transformers ...
