直流稳压电源及漏电保护装置的设计

The Design of DC Regulated Power Supply and Electric Leakage Protection

本装置主要由稳压电源和漏电保护部分组成,直流稳压电源电路主要由调整管、放大器组成,漏电保护由电位器与电流表头组成,取样电阻采用锰铜丝电阻,具有很好的稳定性,继电器控制漏电动作与复位,显示、转换、动作电流的设定由单片机程序等实现。经多次调试改进,装置稳定可靠,能够完成设计要求。

The device is mainly composed of regulated power supply and leakage protection and DC regulated power supply circuit is mainly composed of a regulating tube and amplifier.The leakage protection consists of a potentiometer and a current meter.Using manganese copper resistance,the sampling resistance has good stability.The setting of relay control leakage's action and reset,display,conversion,action current is achieved by the MCU program.After repeated debugging and modification,the device is stable and reliable,able to complete the design requirements.
