煤矿井下高压开关综合保护单元的研制
|
摘要
煤矿井下工作环境特殊,空间狭窄,空气潮湿,负荷波动大,电气设备及供电线路绝缘容易老化,从而会造成漏电、短路、过载、过压、欠压等故障,如不及时发现和处理,将会造成严重后果,危及人身安全和生产安全[6]。
随着数字集成电路的应用与发展,为了适应电器工业不断发展的需求,配电设备与控制系统日益复杂化,对综合保护产品的性能与结构提出了更高的要求。同时,高性能的单片机RAM,数字处理DSP芯片、微机保护装置的不断发展,一些新的保护原理和方案,受到了越来越多的关注,并逐步得到实际应用。本文在分析了目前国内外高压馈电开关保护器的研究进展与现状的基础上,提出了一种新的综合保护器的设计方案。
本论文以TI公司的32位数字信号处理芯片TMS320F2812为核心处理器,研制了一种集多种保护、控制、显示、整定、通信功能为一体的矿用高压馈电开关保护系统。它具有漏电闭锁、短路、过载、欠压、过压等功能保护和故障查询功能,并且采用人机交互界面对电网运行状况及故障情况显示。软件编程采用了模块化结构,便于系统的升级,此外,针对系统可能遇到的各种干扰,在硬件、软件两方面进行了抗干扰设计。
论文最后对馈电开关保护器在实验室结合开发板与实验室设备进行了初步试验,试验结果表明:该保护器能准确地判断电网的各种故障并执行相应操作,性能较稳定,动作可靠,达到了预期设计目标。
The unique environment of coal mines under well and ground , as space limited , the humid air, load fluctuations, the electrical equipment and electrical wiring insulation is prone to aging, thereby causes earth leakage, short circuit, overload, phase failure, over-voltage, under-voltage and so on. If not promptly discovered and disposed of in time, will result in serious accidents. Endangering the personal safety and product safety [6].
With the development and application of digital integrated circuits, in order to meet the evolving needs of electrical industry, distribution equipment and control systems become increasingly complex, comprehensive protection for intelligent devices and structure of the product’s performance put a higher demand. At the same time, high-performance microcontroller RAM, digital signal processing DSP chip continues to emerge, the use of DSP chips as the core of the various coal Smart Protector device gradually applied to the scene.Based on analysis the Progress and Status of current domestic Power feeder switch protector, we design a new kind of intelligent feeder switch comprehensive motor protector.
The text carries on the 32 bits digital signal processing processor TMS320F2812 of Texa Instrument Company to the core of signal acquisition and processing. A new intelligent protective unit provided with protection, control, measuring, display, setting, self-diagnosis and communication function and so on has been developed. The device also has protective steps of leakage locking, short-circuit, and overload, phase-failure, under-voltage, and over-voltage and so on. And it also could display operation and fault complexion using liquid crystal display and it also could have the system for inquiring about fault and communication. Software programming has used modularization configuration for upgrading easily. Furthermore, in allusion to various disturbances that the system may face, this paper puts up the anti-jamming design in two aspects of hardware and software.
Finally,it has been proved by the results of tests in the laboratory that the protector can detect all the faults exactly, reliably and quickly, and execute the corresponding protection; each index meets the design requirements. At the same time, the friendly human-computer can save the time to identify the types of fault and get rid of the fault,which may improve the production efficiency.
