Jieyang City recycles the second-hand transformer 10KV transformer at home. Transformers can be divided into power transformers, test transformers, instrument transformers and special-purpose transformers according to their uses. Power transformers are necessary equipment for power transmission and distribution and power distribution for power users. The test transformer is used to test the withstand voltage (boost voltage) of electrical equipment; Instrument transformer is used for electrical measurement and relay protection of distribution system (PT, CT); Special purpose transformers include electric furnace transformer for smelting, welding transformer, rectifier transformer for electrolysis, small voltage regulating transformer, etc. The commonly used cooling methods of power transformers are generally divided into three types: oil-immersed self-cooling, 油浸风冷,强制油循环。油浸自冷:是通过油的自然对流将热量带到罐壁和散热器管道,再通过空气的对流传导散热。它没有特殊的冷却设备。油浸风冷式:在油浸自冷的基础上,在油箱壁或散热器管上安装风扇,用鼓风机帮助冷却。安装风冷后,变压器容量可提高30%~35%。强制油循环冷却方式可分为强油风冷和强油水冷却。变压器中的油由油泵泵入油冷却器,然后返回油箱。油冷却器做成特殊形状,便于散热。介质通过风机吹风或循环水冷却, 热量被带走。变压器是一种用于转换交流电压和电流并传输交流电能的静态电气设备。
家里收藏二手变压器的两种方式下载方案一:使用RS-232C的com口2:USB口下载。plc上有两个接口,一个是圆形的九针口,一个是miniUSB口,如下图:黄线插入圆形口,蓝线插入小方口。程序编译完成后,如果RS232com口用的是黄色线,在PLC软件中,双击左上角电脑侧I/F行中的连接目标:SerialUSB,双击它:选择一个RS232C,选择com口,如果不知道是哪个com口,打开电脑设备管理器找到端口(com和LPT),就会出现有连接的com口。连接成功后,确认并单击确定。
最基本类型的变压器由两组用导线缠绕的线圈组成,它们以感应的方式相互结合。当一组线圈中流过交流电流(已知频率)时,另一组线圈中会感应出相同频率的交流电压,感应电压取决于两个线圈之间的耦合程度和磁交联程度。
10KV变压器,变压器回收可分为:配电变压器,电力变压器,全密封变压器,组合式变压器,干式变压器,油浸式变压器,单相变压器,电炉变压器,整流变压器等。
