基于DSP的高压断路器控制回路智能防烧模块的研制
|
摘要
高压断路器是电力系统最重要、使用最频繁的一次设备之一。特别是对于老式的断路器,断路器分、合闸线圈长期频繁故障,导致电网负荷损失,增加电网运行风险,降低供电可靠性,且由于断路器内部设计不合理等原因,对其进行检修异常费时费力。针对这一实际生产运行的情况,研发一种基于DSP的高压断路器控制回路智能防烧模块。新型装置不仅能通过程序智能判断断路器的运行状态,当断路器发生故障或者不满足分、合闸要求时,保护装置自动切换断路器的控制回路,以达到保护分、合闸线圈的目的。还能根据电流、电压等参数判断出断路器的工况,对断路器故障进行实时存储,并传输给决策专家库智能判断,实现了高压断路器从"事故检修"过渡到"状态检修"。
High voltage circuit breaker is one of the most important and frequently used primary equipments in power system. Especially for older circuit breakers,its opening/closing coil frequently failures in the long-term operation for power grid companies,which led to load loss,Increases the risk of power grid operation and reduces the power supply reliability. And because the internal design of the circuit break is unreasonable,the maintenance of the circuit breaker is time-consuming and labor-consuming. a high voltage circuit breaker based on DSP control circuit intelligent module is further researched and development for solving the actual production operation. new circuit breaker which adopts intelligent module can look the operation state through program. When the circuit breaker failures,or does not meet the requirements of opening/closing,the device switches control circuit intelligently in order to reach the purpose of protect the opening/closing coil. According to current/voltage and other parameters determine the operation state of circuit breaker,the module can real-time analysis of circuit breaker working condition. It can real-time storage of circuit breaker failure and through the decision-making expert judgment. it realizes the transition from " accident repair" to " maintenance".
