According to numerical simulation and molten steel solidification mechanism , in the paper , the restrict relationship had been setup between casting speed and molten steel level and average mould tapping section thickness as well as its shell temperature at tapping spout 本文基于数值模拟和钢液凝固机理,建立起结晶器内钢液液位和铸坯拉速对其出钢口处钢液截面平均温度和坯壳温度的制约关系。
The analyzing result indicates that when the ambient temperature of compressor rises , the compressor works in an unfavorable ambient and the shell temperature and discharge temperature rise , while the performance and refrigeration capacity reduce . sealing the compressor can reduce the 分析结果表明:压缩机环境温度升高时压缩机工作在一个十分不利的环境中,环境温度的升高导致压缩机的壳温和排气温度升高,性能降低,制冷量减小。
On - line monitoring of hvcb is the precondition of predicting maintenance , is the key element of reliable run , and is the important supplement to the traditional off - line preventive maintenance in fact , the faults are made by hvcb , no matter in number or in times , is over 60 % of total faults so it has determinative importance for improving the reliability of power supply and this can greatly decrease the capital waste used by - dating overhaul in this paper , the inspecting way of hvcb mechanism characteristic is discussed the concept of sub - circuit protector is presented , the scheme that we offered has been combined with sub - circuit integrality monitoring theory , to ensure that it has the two functions as a whole according the shut - off times at rated short circuit given by hvcb manufacturer , the electricity longevity loss can be calculated in each operation , and the remained longevity can be forecast too an indirect way for calculating main touch ' s temperature by using breaker shell temperature , air circumference temperature and breaker ' s heat resistance is improved in this paper , and main touch resistance can be calculated if providing the load current msp430 , a new single chip microcomputer made by ti company , is engaged to develop the hardware system of the on - line monitoring device , and special problem brought by the lower supply voltage range of this chip is considered fully 高压断路器所造成的事故无论是在次数,还是在事故所造成的停电时间上都占据总量60以上。因此,及时了解断路器的工作状态对提高供电可靠性有决定性意义;并可以大大减少盲目定期检修带来的资金浪费。本文论述了断路器机械特性参数监测方法;提出了二次回路保护器的概念,并将跳、合闸线圈完整性监视和二次回路保护结合起来,给出具有完整性监视功能的二次回路保护器实现方案;根据断路器生产厂家提供的断路器额定短路电流分断次数,计算每次分闸对应的触头电寿命损耗,预测触头电寿命;提出根据断路器壳体温度和断路器周围空气温度结合断路器热阻来计算断路器主触头稳态温升的方法,并根据此时的负荷电流间接计算主触头回路的电阻;在硬件电路设计上,采用美国ti公司最新推出的一种功能强大的单片机msp430 ,并充分考虑该芯片的适用电压范围给设计带来的特殊问题;在通信模块的设计中,解决了不同工作电压芯片之间的接口问题,并给出了直接联接的接线方案。
