1.
0 was applied to analyze the ZJ70D electric drilling machine powered by electric network at SK1 oil well.
0对ZJ70D电动钻机电网供电进行了仿真分析,分析表明变电站600V母线电压波形上的振荡是变压器漏感和滤波电容、晶闸管的寄生电容或电路上的分布电容的串联谐振引起的,据此提出了通过减小变压器漏感和加大滤波电容、加大谐振回路上的电感和电阻等措施来有效减小振荡。
6)  Power Supply
供配电

补充资料:不接地配电网
分子式:
CAS号:

性质:与大地没有电气连接的配电网。1~10kV高压配电网、煤矿井下低压配电网采用这种配电网。主要优点是单相接地电流较小、单相电击危险性较小、不容易受其他系统及地下杂散电流的影响。主要不足之处是过电压防护性能不好。国外还有一种经高阻抗接地的配电网。在不接地配电网和经高阻抗接地的配电网中,用电设备裸露的不带电导体应采取保护接地措施。
