通过操作台远程变频起动风机。将风门开至全开位置,在变频器已受电并且允许运行的情况下,将起动转换开关转到“开”位置,风机起动,再次确认电机的运转方向。变频起动与工频起动的明显不同是看不到大的起动电流,而且在整个低速区的运行电流都相当小,在手动模式下,提高引风机速度可看到炉膛负压增大,提高送风机速度可看到炉膛负压减小。在自动模式下,引风机的升、降速按钮改变的是炉膛负压的设定值,改变设定值可看到炉膛负压的改变(引风机速度变化,送风机速度不变);而如果改变送风机速度,就可看到引风机速度随之改变,炉膛负压能保持恒定。
工频运行的引风机长期运行于100~120A电流之间,送风机长期运行于70~100A电流之间。变频运行后,变频器长期工作在10~30Hz之间,引风机电机侧的电流为70~120A,送风机电机侧的电流为50~80A.因为变频器输出侧的电压低于输入侧的电压,因此,变频器输入侧的电流要小于输出侧的电流,引风机电流为25~50A,送风机电流为10~30A.
风机变频运行后,电机的工作速度显著降低,电机和风机的噪声也明显降低,相关机械的寿命得以延长。由于可以取消风道闸门或将闸门开至全开位置,因此,由闸门振动引起的噪声将大为降低。
风机变频改造的工作量相对较少,一般只需安排3~5天的停炉时间即可完成全部工作量。风机变频运行显著的效果是节能,而节能是现代企业降低产品成本,提高产品竞争力的有效手段.
UPS已朝高频化发展,因为高频化结构的UPS具有很多优点,比如它比目前所谓高频机结构UPS的效率高、体积小、输入功率因数高、允许输入电压变化范围大、不需要输出隔离变压器和价格低等,是当前信息中心机房节能的理想选择。但由于高频机结构UPS相对于高频机UPS而言,制造困难,对制造工艺、生产手段要求较高,一般手工方式很难实现规模化和一致性。
因此,也就推迟了高频机UPS的“退休”时间,再加之高频机UPS不论对一般生产者还是一些用户而言都有些恋恋不舍。以手工为主要生产方式的厂家一时还很难上规模,再加之这两方面个别的也存在一些误解,使高频机UPS不能顺利代之以高频机UPS。比如对输出隔离变压器的误解就是一个例子。由于高频机结构UPS取消了用漆包线绕在矽钢片铁心上这种方式的隔离变压器,而高频机UPS就没取消,反而成了高频机结构UPS的优点。这就引出了好多不能取消这个变压器的说法,比如说这个变压器:
*可以在逆变器故障时切断直流电压到负载的通路,防止负载损坏,
*可以抗干扰,
*可以缓冲负载端的短路和突然变化,
*可以提高UPS的可靠性,
*可以耐电网电压的大范围变化,
二、高频机结构全桥逆变器UPS输出变压器的必要性
高频机UPS输出变压器的功能
在上个世纪七十年代,由于半导体器件的水平和品种所限,比如通流能力小和耐压能力差,不得不在输入端加一个降压变压器,经逆变器后再把电压升上去。这种早期的高频机UPS输入端是降压变压器,输出端是升压变压器;另一个特点是输入整流器和后面的逆变器都工作在工业频率,即50Hz(或60Hz)。在一些中小功率UPS中,输入整流器和充电器是分开的。这主要是因为在这些UPS中的输入整流器都是采用的没有任何调整能力的整流二极管,而电池电压的电平是稳定的,需要严格控制的,所以一般需另设具稳压功能的充电器电路。
在小功率中,早期的充电器一般用一个稳压块,到后来才采用了PWM开关电源,提高了充电速度和充电效率。由于中小功率UPS中采用的电池电压很低,所以输出还要加升压变压器。后来由于器件的发展才取消了输入降压变压器,成了今天的样子。
UPS变压器能提高UPS系统的可靠性和稳定性吗?
包括UPS在内的电子设备容易出故障的主要因素是高温。在高温下,器件的漏电流增大、耐压降低。据有阿累纽斯定律介绍,当环境温度在25?C的基础上,每上升10?C,元器件或设备的寿命就减半。当温度按照10?C的算术梯度上升时,元器件或设备的寿命就会按照1/(n=1,2,3…)的几何级数规律递减。而机内的温升来自机内各个电路环节的功耗,变压器是其中之一,如果没有变压器就可以少去这部分功耗。所以从这个意义上说,由于变压器的存在,在程度上降低了系统的可靠性。
