摘要
BVAC.N99D主断路器在我国使用已久,范围大,开关频率高。因此需要经常检查检修。合闸性能、连锁触头状态和分合闸时间在检查该型号主断时十分重妾,设计一款便携式可以控制分合闸并测量分合闸时间的设备很有必妾。该设备电池供电,单片机控制MOS管开闭主断。采用逻辑芯片与单片机配合判断计算分合闸状态与时间,用数码管显示结果,用LED显示连锁开关状态。经过试验证明能安全的进行分合闸,准确的测量分合闸时间,准确的显示连锁状态。
BVAC.N99D mmin circuit breaker has been used for a long time in China with large range and if s action frequency very high.Therefore,regular inspection and maintenance are needed.Closing performanee,interlocking switch state and opening closing time are very important when checking the breaker.It is necessary to design a portable device which cmn control opening closing and measure opening closing time.The device is powered by battery,and the MOS tran sistor is con trolled by SoC.The logic chip and SoC are used to judge and calculate the opening and closing state and time,the digital tube is used to display the results,and the LED is used to display the in terlocking switch state.The test shows that it can safely open and close,accurately measure the openi ng and closing time,and accurately display the interlocking switches state.
