绥化变压器的操作

绥化变压器的操作
    对小型绥化变压器，送电操作较简单，安装或检修工作完成后，按照电业安全工作规程作业，最后就可以送电，先合侧，将侧跌落绥化变压器一一送上，再送侧开关。绥化变压器送电后，应测量三相空载相电压和线电压，空载线电压应在390—410V范围内，否则应调节分接开关。三相空载电压不平衡度应不超过2.5%，否则应查明原因.才准正式投入使用。调节分接开关后，一般宜测量三相绕组的直流电阻，判断接触是否良好，位置是否正常。
 
Transformer operation
 
    Small distribution transformers, power transmission operation is relatively simple installation or repair work is complete, in accordance with electrical safety work
To make a point of order operations, and finally transmission, first close the high pressure side of the high-pressure side drops fuse 11 sent, sending low
Pressure side of the switch. Distribution transformer power transmission should be measured low-voltage three-phase no-load phase voltage and line voltage, no-load line voltage should be
390-410V range, otherwise adjust the tap. Three-phase no-load voltage unbalance should not exceed
2.5%, should otherwise identify the cause before they officially put into use. Adjust the tap, the general should be the measurement of three-phase
Voltage winding of the DC resistance, to determine the contact is good, location is normal.
