Design and Application of Insulation Monitoring Products for DC Systems
In order to improve the safety and stability of DC system operation,solve the problem of DC system insulation monitoring,design a new type of monitoring method of the product.The product is based on the design of unbalanced bridge circuit with high-precision external ADC sampling chip and STM32F401 chip,which can realize the demand of high-speed,high-precision,and high-voltage measurement.The product can be applied in DC systems,such as insulation monitoring of DC systems for energy storage DC side,substation DC panels,UPS DC power supply systems,electric vehicle DC charging devices,photovoltaic DC systems and so on.
