摘要
针对数字式继电保护装置测试中的模拟断路器动作时间不可控,进而影响到保护装置整组动作及其它功能的测试的问题,设计一种基于msp430单片机芯片并辅加简单外围电路所构成的模拟断路器。该装置可通过软件调整模拟断路器固有合闸与跳闸时间,并可方便地接收数字式继电保护装置发出的保护动作信号,显示断路器各相的状态。经测试,该模拟断路器可有效提高继电保护及安全自动装置的测试质量。
In the test of digital relay protection device, the operation time of simulated circuit breaker is not controllable, it will affect the whole group action test for digital relay protection device and other functional test. A software written by MSP430 microcontroller is designed by aided simple peripheral circuit to adjust the closing and tripping times of simulated circuit breaker. The simulated circuit breaker can receive the action signals of digital relay protection equipment, and display the state of circuit breaker. The simulated circuit breaker can effectively improve the quality of test of relay protection and automatic safety devices.
