Research influencing of instability a supply voltage on operation the industrial equipment of microwave drying

Research has been carried out on large supply voltage instability influence on the functioning efficiency of microwave drying equipment, including all its units and assemblies. It has been determined that a 15-20% increase or decrease from the nominal value has little practical influence on the microwave drying equipment functioning and technical/economic parameters. However, its increase leads to accelerated wear and a decrease in reliability and operating life. It has been shown that the microwave drying equipment internal magnetron generators can be protected from circuit supply voltage increases by the use of input resistor block sections.
