| 我们一般指PT柜加装消谐器，是指安装在6-35kV电磁式电压互感器（简称压变）一次绕阻Yo结线中性点与地之间的非线性电阻器，起阻尼与限流的作用。在6-35kV发电、变电站，我们经常碰到的是电网中性点不接地，其母线上的Yo接线的电磁式压变一次绕组，成为中性点不接地电网对地的唯一金属通道，电网相对地电容的充、放电途径 必然通过压变一次绕组 We generally refer to the installation of harmonic eliminator in PT cabinet. It refers to the non-linear resistor installed between the neutral point of Yo junction and the ground of 6-35kV electromagnetic voltage transformer (VT), which plays the role of damping and current limiting. In 6-35kV power www.lhsilicone.cnwww.gzcucaoduyi.cn www.china-pipe.com.cnwww.chenyei2009.cnzhixuedai.71ix.compesuomo.37ix.com.cngeneration and substation, we often encounter that the neutral point of the power grid is not grounded. The electromagnetic voltage transformer primary winding of Yo connection on the bus becomes the only metal channel of the neutral point ungrounded power grid to the ground. The way of charging and discharging the relative ground capacitance of the power grid must be through the voltage transformer primary winding. |
