In this thesis, soft starter equipment realized by thyristors power transform circuit is studied. To improve equipment performance, we apply variable reactance technique to AC motor soft starter study. The high voltage AC working winding of reactance is in series with motor winding, while low voltage control winding and thyristors groupware with intelligent controller constitute close loop circuit. We adopt thyristor phase control voltage-regulator mode to control low voltage winding, then control the reactance of high voltage winding, and then arrive at the goal-control the current and voltage of motor AC to realize motor soft starting.

The default settings put in place in a few easy steps during the installation seem ideal for general purpose use, information and alerting is clear and helpful without ever seeming intrusive or scare-mongering, and detailed configuration is about as straightforward and painless as such things can be. With the user experience reduced to an installation process, and possibly the occasional alert as another attack is spotted and blocked effortlessly, the unobtrusiveness is further enhanced by the product's legendary lightning speed, miraculously unimpeded by the additional protection, keeping overheads to a level barely noticeable on modern high-powered systems.
默认设置落实到位,在几个简单的步骤,在安装过程中,似乎理想的,为一般用途使用,信息和告警是明确的很有帮助而不似侵扰或危言耸听,并详细配置,是因为直率,毫不费力,因为这样的事情可以随用户体验减少,使安装过程中,并可能偶尔警觉另一种攻击是被检举,并堵塞毫不费力, unobtrusiveness是进一步提高产品的富有传奇色彩的闪电速度,奇迹般地畅通所额外保护,同时间接到一定程度,几乎没有明显的现代高功率系统。

When proceeding pump testing, we collect a good many parameters, and figure out the pump gross head, pump shaft power, NPSH and other parameters. Different units of those parameters are used in different countries, and sometimes the customer asks for the test data of special media. Making a test of every medium of the same pump is not realistic, and the costs will be increase, so we convert the units of the data, and figure out the testing data according to different customer's special requirements. We reduced costs and got good remarks from the corporation through the application of unit conversion technology.
水泵试验时,要采集诸多参数,并且根据这些参数计算出扬程、轴功率、NPSH等数值,不同国家这些参数采用的单位不同,企业必须能够按照客户要求的单位提供试验数据;并且有时客户要求得到水泵在特殊介质下进行试验得出的试验数据,同一台泵在每种介质下都做一遍试验不太现实,而且会提高企业的生产成本,提出将采集的数据进行单位换算,根据不同国家或者客户的特殊要求求出泵的试验数据,在实际应用中节省了试验成本,得到了企业的好评。
