Problems solved by technology
[0004] 1. The existing power distribution switch adopts the master-slave distribution control mode. When the master fails, all the slave control switches will fail. At the same time, there is a possibility of misoperation of the control switch, which will cause a safety failure of the power grid.
[0005] 2. The switching time is long. The switching time of the current power switch is greater than 20ms, which will cause the reset of the electrical equipment, etc.

A power supply for providing electric energy for the three-phase automatic load adjusting system is also arranged in the switch housing. The phase-change switch type three-phase automatic load adjusting device adopts a neural network structure and a fuzzy algorithm, the safety and reliability problems of switches are solved on the aspect of system architecture, and thereliability of the switches is greatly improved.
Description
technical field [0001] The invention belongs to the field of power systems, and relates to a phase-change switch type three-phase load automatic adjustment device. Background technique [0002] With the improvement of people's lives, people's demand for electrical appliances continues to grow, resulting in a continuous increase in electrical loads, but civilian electricity is 220VAC single-phase electricity; we know that the voltage from 10KV or higher is transformed into 380VAC power through an isolation transformer Three-phase electricity, while 220VAC civilian electricity is composed of a power line and a neutral line, which has a natural structural defect. When the power of each power line is not equal, it will cause the output of the transformer to be unbalanced, resulting in increased The power loss of the line will increase the power loss of the distribution transformer, reduce the output of the distribution transformer, generate zero-sequence current from the distrib...
